Nuo Therapeutics, Inc.: Form 10-K for the period ended Dec 31, 2023

Corporate Overview

Nuo Therapeutics, Inc. is a Delaware corporation organized in 1998 under the name Informatix Holdings, Inc. In 1999, Autologous Wound Therapy, Inc., an Arkansas Corporation, merged with and into Informatix Holdings, Inc. and the name of the surviving corporation was changed to Autologous Wound Therapy, Inc. In 2000, Autologous Wound Therapy, Inc. changed its name to Cytomedix, Inc. (“Cytomedix”). In 2001, Cytomedix, filed for bankruptcy, from which it emerged in 2002 under a Plan of Reorganization. In September 2007, Cytomedix received 510(k) clearance for the Aurix System (“Aurix”), formerly known as the AutoloGel™ System, from the U. S. Food and Drug Administration (“FDA”). In April 2010, Cytomedix acquired the Angel Whole Blood Separation System from Sorin Group USA, Inc. In February 2012, Cytomedix, acquired Aldagen, Inc. (“Aldagen”), a privately held developmental cell-therapy company located in Durham, NC. In 2014, Cytomedix changed its name to Nuo Therapeutics, Inc. In 2016, Nuo filed for and emerged from bankruptcy under Chapter 11. Effective May 1, 2019, Nuo furloughed its remaining employees and ceased standard operational activities as it awaited developments concerning its reconsideration request with the Centers for Medicare & Medicaid Services (“CMS”) regarding Medicare coverage for Aurix. Based on a favorable National Coverage Determination (“NCD”) issued in April 2021, Nuo initiated restart activities for the business beginning in October 2021. Aldagen is a non-operational, wholly owned subsidiary of Nuo. Our principal offices are presently located in Houston, Texas.

Our Business

We are a regenerative therapies company focused on developing and marketing products for chronic wound care primarily within the U.S. We commercialize innovative cell-based technologies that harness the regenerative capacity of the human body to trigger natural healing. The use of autologous (i.e., from self, the patient’s own) biological therapies for tissue repair and regeneration is part of a clinical strategy designed to improve long-term recovery in inherently complex chronic conditions with significant unmet medical needs.

Our current commercial offering consists of a point of care technology for the safe and effective separation of autologous blood to produce a platelet-based therapy for the chronic wound care market. This offering is known as “Aurix” or the “Aurix System”. The FDA cleared the Aurix System for marketing in 2007 as a device under Section 510(k) of the Federal Food, Drug, and Cosmetic Act (“FDCA”). Aurix is one of two platelet derived products cleared by the FDA for chronic wound care use and is indicated for most exuding wounds. The advanced wound care market, within which Aurix competes, is composed of advanced wound care dressings, wound care devices, and wound care biologics, and is estimated to be an approximate $10.8 billion global market in 2021 with the North American market estimated at approximately $4.15 billion in 2020. Estimates remain that 1-2% of population in the developed countries will suffer from a chronic wound at least once in their lifetime. According to the National Institute of Health, treatment of diabetic foot ulcers cost an estimated $9-$13 billion annually in the U.S. alone. An aging population and the still increasing prevalence of diabetes suggests a continued increase in the patient population at risk of developing chronic, non-healing wounds.

The Aurix System produces a platelet rich plasma (“PRP”) gel at the point of care using the patient’s own platelets and plasma sourced from a small draw of peripheral blood. Aurix comprises a natural, endogenous complement of protein and non-protein signal molecules that contribute to effective healing. During treatment, the patient’s platelets are activated and release hundreds of growth factor proteins and other signaling molecules that form a biologically active hematogel. Aurix delivers concentrations of the natural complement of cytokines, growth factors and chemokines that are known to regulate angiogenesis (i.e., the development of new blood vessels), cell growth, and the formation of new tissue. Once applied to the prepared wound bed, the biologically active Aurix hematogel can restore the balance in the wound environment to transform a non-healing wound to a wound that heals naturally.

In 2012, a Medicare National Coverage Determination (“NCD”) from CMS reversed a twenty-year old non-coverage decision for autologous blood derived products used in wound care. This NCD allowed for Medicare coverage under the Coverage with Evidence Development (“CED”) program. CED programs have been employed for a selected number variety of other therapies, including transcatheter aortic valve repair and cochlear implantation. Under the CED program, CMS provides reimbursement for items or services on the condition that they be furnished in approved clinical protocols or in the collection of additional clinical data. Under the CED program, a facility treating a patient with Aurix was reimbursed by Medicare when health outcomes data were collected to inform future coverage decisions. The intent of the CED program was to evaluate the outcomes of Aurix therapy for the broader Medicare population when it is used in a “real world” continuum of care.

On May 17, 2019, we transmitted a letter memorandum to CMS’ Coverage and Analysis Group (“CAG”) in support of our complete formal request for reconsideration of the then existing national coverage determination based on clinical data collected and published under the CED program. The complete formal public request for reconsideration was made on May 8, 2019 in accordance with the applicable requirements.

On April 13, 2021, CMS issued a final coverage decision memo indicating that Medicare would nationally cover autologous PRP for the treatment of chronic non-healing diabetic wounds for a duration of 20 weeks under Section 1862(a)(1)(A) of the Social Security Act. This coverage applies when using devices whose FDA-cleared indications include the management of exuding cutaneous wounds, such as diabetic ulcers. Coverage of autologous PRP beyond 20 weeks for diabetic foot ulcers and for the treatment of all other chronic, non-diabetic, non-healing wounds will be determined by local Medicare Administrative Contractors.

Although FDA cleared the Aurix System for marketing in 2007 under Section 510(k) of the FDCA, CMS only established economically viable reimbursement for the product beginning in 2016. For 2022, the CMS national average reimbursement rate for the Aurix System is $1,749 per treatment, which we believe provides appropriate payment to facilities for product usage. We will market the Aurix System at an approximate cost of $800 per treatment to wound care providers in the hospital outpatient setting.

Our Strategy

Our current commercial focus is establishing engagement with providers treating chronic non-healing wounds to demonstrate the clinical benefits we believe result from the use of Aurix in the treatment of complex wounds. Increasing physician awareness of the differentiating attributes of Aurix will be key to establishing a base of product revenues upon which to grow. We anticipate developing these relationships with clinical providers and treatment facilities primarily by establishing a variety of distributor arrangements throughout the United States. Our commercial team consists of five senior employees who are leveraging their current and historical relationships to establish distributor arrangements. As of December 31, 2023, we had established contractual relationships with more than 200 individual distributor representatives including. a multi-state agreement with Pacific Medical, Inc. covering multiple large markets in the western United States. The number of distributor representatives may continue to expand modestly in the months ahead, but the current focus is establishing commercial customer relationships with wound care providers in primarily hospital outpatient wound care clinics and ensuring that the reimbursement mechanisms are appropriately administered by the local Medicare Administrative Contractors in support of the April 2021 NCD.

Commercially available Aurix product was first available in late May 2022 for demonstration and evaluation purposes. Through a growing distributor network, Aurix is presently being evaluated by various hospital/facility Value Analysis Committees (VACs) as part of the process of approving its clinical use. Limited initial commercial revenues were recorded during the second half of 2022, revenues increased to approximately $610,000 in 2023, and we expect revenues to exhibit continued growth in future periods.

The Science Underlying Aurix/Platelet Rich Plasma

Normal Wound Healing

The science underlying wound healing is well-established. An immediate early event critical for wound healing is the influx of platelets to the wound site. Platelets bind to elements within damaged tissue such as collagen fragments and endogenous thrombin molecules and are activated to release a diversity of growth factors and other biomolecules from their alpha and dense granules (Reed 2000, Nieswandt, 2003). These biomolecules provide signals essential for biological responses regulating hemostasis and effective tissue regeneration.

Chronic Wounds

Dysregulation of numerous cellular and biological responses contribute to the chronic wound phenotype. Chronic wounds have reduced levels of growth factors and concomitant decreases in cellular proliferation (Mast 1996). There is increased cellular senescence (Telgenhoff 2005), and there generally is a lack of perfusion that can inhibit the delivery of nutrients and cells required for regeneration (Guo 2010). As the body attempts to stave off infection, elevated concentrations of free radicals accumulate in the chronic wound and further damage surrounding tissue (Moseley 2004, James 2003).

Aurix Therapy

Aurix has been cleared by FDA as safe and effective with an indication for chronic wounds such as leg ulcers, pressure ulcers, and diabetic ulcers and other exuding wounds such as mechanically or surgically debrided wounds. The Aurix therapeutic is formed by mixing a sample of a patient’s platelets and plasma with pharmaceutical grade thrombin and ascorbic acid. The thrombin activates platelets while ascorbic acid drives the synthesis of high tensile strength collagen, clears damaging free radicals and controls gel consistency. The topical dermal application of Aurix gel bypasses the lack of local perfusion to provide immediate signals for new tissue formation and ultimately healing.

The Efficacy of Aurix Relates to Biological Activity Released by Platelets

Regenerative Capacity

More than 300 proteins are released by human platelets in response to thrombin activation (Coppinger 2004). Important examples include vascular endothelial cell growth factor (“VEGF”), platelet derived growth factor (“PDGF”), epidermal growth factor (“EGF”), fibroblast growth factor (“FGF”) and transforming growth factor-beta (“TGF-B”) (Eppley 2004, Everts 2006). These proteins are critical for organized wound healing, regulating responses such as vascularization, cell proliferation, cell differentiation, and deposition of new extracellular matrix (Goldman 2004). Platelets also release chemokines such as Interleukin-8 (“IL-8”), stromal cell derived factor-1 (“SDF-1”), and platelet factor-4 (“PF-4”) (Chatterjee 2011, Gear 2003) that control the mobilization and migration of stem cells and fibroblasts (Werner 2003 and Gillitzer 2001), which contribute to tissue regeneration.

Anti-infective Activity

Populations of bioburden in chronic wounds vary over time and wounds invariably retain or become re-infected with some level of bacteria that is detrimental to healing (Howell-Jones 2005). In addition to regenerative capacity, platelets release anti-microbial peptides effective against a broad range of pathogens including Methicillin Resistant Staphylococcus Aureus (“MRSA”) (Moojen 2007, Jia 2010, Tang 2002, Bielecki 2007).

Clinical Efficacy

Multiple efficacy and effectiveness studies have been published in peer reviewed journals documenting the impact of using Aurix to treat chronic wounds. Key data include:

• In the published study of the clinical data collected during the CED program for diabetic foot ulcers, Aurix demonstrated a significant time to heal advantage compared to wounds treated with usual and customary care (including any available advanced therapy). A higher percentage of healing was observed across all wound severities (Wagner Grade 1-4) and in a patient population with significant comorbidities. (Gude W, Hagan D, Abood F, Clausen P: Aurix Gel is an Effective Intervention for Chronic Diabetic Foot Ulcers: A Pragmatic Randomized Controlled Trial. Advances in Skin and Wound Care, 2019; 32(9): 416-426.)
• In a double blinded randomized controlled trial, 81% of the most common-sized diabetic foot ulcers healed with Aurix compared with 42% of control wounds. Mean time to healing was six weeks. (Driver V, Hanft J, Fylling, C et al.: A Prospective, Randomized, Controlled Trial of Autologous Platelet-Rich Plasma Gel for the Treatment of Diabetic Foot Ulcers. Ostomy Wound Management, 2006; 52(6): 68-87.)
• In 285 chronic wounds in 200 patients, 96.5% of the wounds had a positive response within an average of 2.2 weeks with an average of 2.8 Aurix treatments (de Leon J, Driver VR, Fylling CP, Carter MJ, Anderson C, Wilson J, et al.: The Clinical Relevance of Treating Chronic Wounds with an Enhanced Near-physiological Concentration of Platelet-Rich Plasma (PRP) Gel. Advances in Skin and Wound Care, 2011; 24(8), 357-368.)
• In a retrospective, longitudinal study of 40 Wagner grade II through IV diabetic foot ulcers, most with critical limb ischemia, wounds increased in size in the approximate 100 days prior to the initiation of comprehensive wound care treatment. Upon treatment with debridement, revascularization, antibiotics and off-loading, the wounds continued to increase in size over a subsequent 75-day period. Once they were then treated with Aurix, the wounds immediately changed healing trajectory and 83% of the wounds healed with an average of 6.1 Aurix treatments per wound (Sakata, J., Sasaki, S., Handa, K., et al. A Retrospective, Longitudinal Study to Evaluate Healing Lower Extremity Wounds in Patients with Diabetes Mellitus and Ischemia Using Standard Protocols of Care and Platelet-Rich Plasma Gel in a Japanese Wound Care Program. Ostomy Wound Management, 2012; 58(4):36-49.)

Customer Concentration

Our revenues are derived from the sale of the Aurix product to customers consisting of primarily hospital outpatient wound care clinics and other private practice physicians treating chronic wounds. The Aurix product became commercially available for sale again in mid-2022 with limited revenues generated during the balance of the year ended December 31, 2022. Product revenues increased to $610,000 for the year ended December 31, 2023.

Licenses and Property Rights

Nuo relies on a combination of trademarks, trade secrets, copyright laws as well as confidentiality agreements, contractual provisions, and other similar measures, to establish and protect its business interests.

Government Regulation

Government authorities in the U.S., Canada, the European Union, and other countries extensively regulate pharmaceutical products, biologics, and medical devices. The Company’s products and product candidates are subject to approval or clearance by the governing bodies prior to and during the marketing and distribution of a product. Regulatory requirements apply to, but are not limited to, research and development, safety and efficacy, clinical studies, manufacturing, labeling, distribution, advertising and marketing, and the import and export of products. Before a product candidate is approved by the governing bodies for commercial marketing, rigorous preclinical and human clinical testing may be necessary to determine the safety and efficacy or effectiveness of the product. If the Company fails to comply with the applicable laws and regulations at any time during the product development process, approval, or clearance process, or during commercialization, it may become subject to administrative and/or judicial sanctions. These sanctions may include, but are not limited to, refusal to approve or clear pending applications, withdrawals of approvals, clinical holds, warning letters, product recalls, product seizures, total or partial suspension of the Company’s operations, injunctions, fines, civil penalties and/or criminal prosecution. Any enforcement action could have a material adverse effect on the Company.

Medical Device Regulation

The Company reinitiated manufacture and available commercial distribution of the Aurix System in May 2022. As such, this and future products manufactured and/or distributed by the Company may be subject to regulations by the applicable governing bodies, including but not limited to, the FDA, Health Canada, the European Medicines Agency, the Japanese Ministry of Health & Welfare, and other regulatory agencies. The Company currently has no meaningful business development initiatives outside of the U.S. Each of the foreign governing bodies noted above serves a similar function as the FDA. As such, the Company and its products and product candidates are subject to the regulations enforced by the outside governing bodies. These regulations include, but are not limited to, product clearance, documentation requirements, good manufacturing practices and medical device reporting. Labeling and promotional activities are also subject to regulation by the U.S. Federal Trade Commission, in certain circumstances. Current enforcement policies prohibit the marketing of approved medical devices for unapproved uses. Each governing body reviews the labeling and advertising of medical devices to ensure that unapproved uses are not promoted. Before a new medical device can be introduced to the market, the manufacturer must obtain clearance or approval from the applicable regulatory agency, depending upon the device classification. In the U.S., medical devices are classified into one of three classes — Class I, II, or III. The regulations enforced by the FDA and/or the appropriate governing bodies to the medical device(s) provide reasonable assurance that the device is safe and effective. In the U.S., Class I devices are non-critical products that the FDA believes can be adequately regulated by “general controls” which include provisions relating to labeling, manufacturer registration, defect notification, records and reports, and current good manufacturing practices, or cGMP, based on the FDA’s Quality Systems Regulations. Most Class I devices are exempt from pre-market notification, and some are also exempt from cGMP requirements. Class II devices are products for which the general controls of Class I devices, by themselves, are not sufficient to assure safety and effectiveness and, therefore, require additional controls. Additional controls for Class II devices may include performance standards, post-market surveillance patient registries, and the use of FDA guidelines. Standards may include both design and performance requirements. Class III devices have the most restrictive controls and require pre-market approval by the FDA. Generally, Class III devices are limited to life-sustaining, life-supporting or implantable devices. All of the governing bodies with responsibility over the Company’s products have the ability to inspect medical device manufacturers, order recalls of medical devices in some circumstances, seize non-complying medical devices, and to pursue prosecution of either civil or criminal violations.

Section 510(k) of the Federal Food, Drug, and Cosmetic Act (“FDCA”) requires individuals or companies manufacturing medical devices intended for human use to file a notice with the FDA at least ninety days before intending to introduce the device into the market. This notice, commonly referred to as a 510(k) premarket notification, must identify the type of classified device into which the product falls, the class of that type, and a specific product already being marketed or cleared by the FDA and to which the product is “substantially equivalent.” In some instances, the 510(k) must include data from human clinical studies to establish “substantial equivalence.” The FDA must agree with the claim of “substantial equivalence” before the device can be marketed. The statutory time frame for clearance of a 510(k) is ninety days, though it often takes longer. Nuo currently only markets a product that is subject to 510(k) clearance.

The Company expects to market the Aurix System by May 2022, consisting of the Aurix Wound Dressing Kit, Aurix Reagent Kit, and Aurix System Centrifuge II. Each component of the Aurix System is a legally marketed product that has been cleared by FDA. The Aurix System Centrifuge II, when used with the Aurix Wound Dressing Kit and Aurix Reagent Kit, are suitable for use on exuding wounds such as leg ulcers, pressure ulcers and diabetic ulcers, and for the management of mechanically or surgically debrided wounds.

As a specification developer, manufacturer, and distributor of medical devices, the Company complies with other regulations and standards, such as the FDCA and implementing regulations set forth in 21 CFR et seq. and also ISO 13485. As a manufacturer and distributor of medical devices, the Company, and in some instances its subcontractors, is required to register its facilities and products manufactured annually with the appropriate governing bodies and certain state agencies. Additionally, the Company is subject to periodic inspections by the governing bodies to assess compliance with cGMP regulations. Facilities may also be subject to inspections by other federal, foreign, state, or local agencies. Accordingly, manufacturers such as the Company must continue to expend time, money, and effort around production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

Fraud and Abuse Laws

The Company may also be indirectly subject to federal and state anti-kickback and physician self-referral laws. Federal physician self-referral legislation (commonly known as the Stark Law) prohibits, subject to certain exceptions, physician referrals of Medicare and Medicaid patients to an entity providing certain designated health services (“DHS”) if the physician or an immediate family member has a financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral, and any person collecting any amounts in connection with an unlawful referral is obligated to refund such amounts. CMS has issued numerous regulations containing exceptions to the prohibitions of the Stark Law. If a physician and a DHS entity have financial relationship subject to the Stark Law, then an exception must be met or else the DHS entity cannot bill for the service. A person who engages in a scheme to circumvent the Stark Law’s referral prohibition may be fined up to $100,000 for each such arrangement or scheme. The penalties for violating the Stark Law also include civil monetary penalties of up to $15,000 per referral and possible exclusion from federal health care programs such as Medicare and Medicaid. Violations of the Stark Law have also been the basis for False Claims Act actions, discussed below. Various states have corollary laws to the Stark Law (so-called “baby Stark” laws), including laws that require physicians to disclose any financial interest they may have with a health care provider to their patients when referring patients to that provider. Both the scope and exception for such laws vary from state to state.

The Company may also be subject to federal and state anti-kickback laws. Section 1128B(b) of the Social Security Act, commonly referred to as the Anti-Kickback Law, prohibits persons from knowingly and willfully soliciting, receiving, offering or providing remuneration, directly or indirectly, in cash or in kind, to induce either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment may be made under a federal health care program, such as Medicare and Medicaid. The Anti-Kickback Law is broad, and it prohibits many arrangements and practices that are otherwise lawful in businesses outside of the health care industry. The Office of the Inspector General (“OIG”) of the U.S. Department of Health and Human Services (“DHHS”) has issued regulations, commonly known as “safe harbors” that set forth certain provisions which, if fully met, will assure health care providers and other parties that they will not be prosecuted under the federal Anti-Kickback Law. Although full compliance with these provisions ensures against prosecution under the Anti-Kickback Law, the failure of a transaction or arrangement to fit within a specific safe harbor does not necessarily mean that the transaction or arrangement is illegal or that prosecution under the federal Anti-Kickback Law will be pursued. As with the Stark Law, violations of the Anti-Kickback Law can result in a False Claims Act action. Many states have adopted laws similar to the federal Anti-Kickback Law, and some of these state prohibitions apply to patients for health care services reimbursed by any source, not only federal health care programs such as Medicare and Medicaid.

In addition, there are other U.S. health care fraud laws to which the Company may be subject that prohibit knowingly and willfully executing or attempting to execute a scheme or artifice to defraud any health care benefit program, including private payers (“fraud on a health benefit plan”) and that prohibit knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement or representation in connection with the delivery of or payment for health care benefits, items or services. These laws apply to any health benefit plan, not just Medicare and Medicaid.

The Company may also be subject to other U.S. laws that prohibit submitting, or causing to be submitted, claims for payment or causing such claims to be submitted that are false. Violation of these false claims’ statutes may lead to civil money penalties, criminal fines and imprisonment, and/or exclusion from participation in Medicare, Medicaid and other federally funded state health programs. These statutes include the federal False Claims Act, which prohibits the knowing filing of a false claim (or causing the submission of a false claim) or the knowing use of false statements to obtain payment from the U.S. federal government. Under provisions of the Affordable Care Act, the failure to report and refund an overpayment to the Medicare or Medicaid programs within 60 days of the identification of the overpayment may also be an obligation subjecting the defendant to a False Claims Act action. Finally, a recent U.S. Supreme Court case, Universal Health Services v. United States ex rel. Escobar, upheld the “implied false certification” theory under which a defendant submits a claim for payment that makes a specific representation about the goods or services provider, but fails to disclose the defendant’s noncompliance with a statutory, regulatory, or contractual requirement that would be material to the Government’s payment decision. When an entity is determined to have violated the False Claims Act, the entity must pay three times the actual damages sustained by the government, plus mandatory civil penalties. Suits filed under the False Claims Act can be brought by an individual on behalf of the government (a “qui tam action”). Such individuals (known as “qui tam relators”) may share in the amounts paid by the entity to the government in fines or settlement. In addition, certain states have enacted laws modeled after the False Claims Act. “Qui tam” actions have increased significantly in recent years causing greater numbers of health care companies to have to defend false claim actions, pay fines or be excluded from the Medicare, Medicaid or other federal or state health care programs as a result of an investigation arising out of such action.

Several states also have referral, fee splitting and other similar laws that may restrict the payment or receipt of remuneration in connection with the purchase or rental of medical equipment and supplies. State laws vary in scope and have been infrequently interpreted by courts and regulatory agencies but may apply to all health care products and services, regardless of whether Medicaid or Medicare funds are involved.

Employees

The Company had 9 full-time employees as of December 31, 2023 which are all compensated as salaried employees. None of the Company’s employees is covered by a collective bargaining agreement or represented by a labor union. The Company considers its employee relations to be good.

Research and Development

During the years ended December 31, 2023 and 2022, we incurred no significant costs for research and development activities.

Competition

While Aurix has limited competition in the chronic wound care market from any other FDA cleared platelet derived products, we face competition from pharmaceutical companies, biopharmaceutical companies, medical device companies, and other competitors in the areas of advanced wound care dressings, wound care devices, and wound care biologics. Leading companies in the advanced wound care market include Smith and Nephew, 3M, MoInlycke, and ConvaTec. Leading competitors in the wound care market that offer other biologic products such as tissue-based products include companies such as MiMedx, Organogenesis, Integra Life Sciences, as well as a significant number of smaller companies. While we believe that Aurix can compete favorably based on broad application across multiple wound etiologies, we expect that many physicians and allied professionals will continue to employ other treatment approaches and technologies, separately and in combination, in an attempt to treat chronic and hard-to heal wounds. The chronic wound market has many therapies that compete with Aurix that have established habitual use patterns and provider contracts to encourage standardized use. Furthermore, other companies have developed or are developing products that could be in direct future competition with our current product line. We may not be able to compete effectively against such companies. Many of these companies have substantially greater capital resources, larger marketing staff and more experience in commercializing products than we do. See “Item 1A. Risk Factors – Risks Relating to Our Business, Industry, and Regulatory Approval of Our Product - Our Product Has Existing Competition in the Marketplace.”

Raw Materials

A reagent, bovine thrombin (Thrombin JMI), used for our Aurix product is available exclusively through Pfizer. Pfizer may unilaterally raise the price for the reagent. If a temporary or permanent interruption in the supply of the reagent were to occur, or the manufacturing costs charged by Pfizer exceed what we can reasonably afford, it would have a material adverse effect on our business.

Available Information

We file annual, quarterly, and current reports, proxy statements and other information with the SEC. The SEC maintains an internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC at http://www.sec.gov. We also make available through our website at www.nuot.com (http://www.nuot.com) our Annual Report on Form 10-K, our quarterly reports on Form 10-Q and current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we have filed it electronically with, or furnished it to, the SEC. Information appearing on, and accessible through, our website is not part of this Annual Report.

An investment in the Company involves a high degree of risk. Before making an investment decision with respect to our common stock, you should consider the risks described below in addition to the cautionary statements and risks described elsewhere and the other information in this Annual Report and in our other filings with the SEC, including subsequent reports on Forms 10-Q and 8-K. The risks described below may not be the only risks the Company faces. Additional risks not yet known or currently believed to be immaterial may also impair our business. If any of these known or unknown risks or uncertainties actually occurs, our business, financial condition or results of operations could suffer and our common stock could be adversely impacted, resulting in a loss of part or all of your investment.

Risks Related to Our Financial Position

Our Revenue Base Is Limited to a Single Product Seeking Market Adoption; We Need Substantial Additional Financing and Our Ability to Affect Such Financing Successfully Could Be Limited

Our current revenue base is limited to our Aurix product, and our Aurix revenue has been limited to date. We have a history of losses and are not currently profitable. For the year ended December 31, 2023, we incurred a net loss of approximately $3.2 million. Even if we succeed in raising substantial additional funds, we expect to incur losses and negative operating cash flows in the immediate future. We may never generate sufficient revenues to achieve and maintain profitability.

Historically, we have financed our operations through a combination of the sale of debt, equity and equity-linked securities, licensing, royalty, and product revenues. Until we can generate a sufficient amount of revenues to finance our cash requirements, which we may never do, we need to finance future cash needs. It is substantially uncertain whether we will be able to obtain such financing on satisfactory terms or at all.

If adequate capital cannot be obtained on a timely basis and on satisfactory terms, it would have a material adverse effect on our ability to implement our business plan, and our revenues and operations and the value of our common stock would be materially and negatively impacted, and we may be forced to curtail or cease our operations.

We Have a Limited Operating History and Limited Operating Experience

We only recently began re-implementing our commercialization strategy for Aurix in the second half of 2022. Thus, we have a very limited operating history. Continued operating losses, together with the risks associated with our ability to gain new customers for Aurix, may have a material adverse effect on our liquidity. We may also be forced to respond to unforeseen difficulties, such as decreased demand for our products and services, downward pricing trends, regulatory requirements, and unanticipated market pressures.

Our Financial Position Creates Doubt as to Whether We Will Continue as a Going Concern

The Company reestablished commercial operations in 2022 and generated limited revenues of approximately $112,000 for the year ended December 31, 2022. For the year ended December 31, 2023, product revenues increased to approximately $610,000. For the years ended December 31, 2023 and 2022, the Company had a net loss of approximately $3.2 million in each year. There can be no assurances that we will be able to achieve a level of revenues adequate to generate sufficient cash flow from operations or obtain funding from additional financing through private placements, public offerings and/or bank financing necessary to support our working capital requirements. It is uncertain whether we will be able to obtain such financing on satisfactory terms or at all. Our continuing losses and limited cash resources raise substantial doubt about our ability to continue as a going concern, and we need to raise substantial additional funds in order to continue to conduct our business. If we are unable to secure sufficient capital to fund our operating activities, we may be forced to delay the completion of, or significantly reduce the scope of, our current business plan, delay the pursuit of commercial insurance reimbursement for our wound treatment technologies, and postpone the hiring of new personnel.

We May Issue Additional Equity or Debt Securities Which Will Likely Dilute and May Materially and Adversely Affect the Price of Our Common Stock

Additional issuance of our common stock or other equity or convertible debt securities will likely dilute the ownership interests of our stockholders. Sales of substantial amounts of shares of our common stock in the public market, or the perception that those sales may occur, could negatively affect the market price of our common stock. We have used, and will likely continue to use, our common stock or securities convertible into or exchangeable for common stock to fund working capital needs or to acquire technology, product rights or businesses, or for other purposes. If additional equity and/or equity-linked securities are issued, particularly during times when our common stock is trading at relatively low-price levels, the price of our common stock may be materially and adversely affected.

We May Not Be Able to Timely and Accurately Report Our Financial Results or Prevent Fraud If We Are Unable to Maintain Effective Disclosure and Internal Controls

Effective disclosure controls and procedures and internal control over financial reporting is necessary for us to provide reliable financial reports in a timely manner. Our management concluded there was a material weakness in our internal control over financial reporting as of the period covered by this Form 10-K. Although we have taken steps to remediate such weakness, the material weakness cannot be considered remediated until the controls operate for a sufficient period of time and management concludes that our internal controls are operating effectively. While we believe that our intended remediation efforts will resolve the identified material weakness, there is no assurance that such efforts will be sufficient or that additional actions will not be necessary, which may undermine our ability to provide timely, accurate and reliable reports on our financial and operating results. Further, if we remediate our current material weakness but identify new material weaknesses in our internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports and the value of our common stock may be negatively affected. As a result of such failures, we could also become subject to investigations by the SEC, or other regulatory authorities, and become subject to litigation from investors and stockholders, which could harm our reputation, financial condition or divert financial and management resources from our business.

The Success of Aurix Is Dependent on Acceptance by the Medical Community

The commercial success of our product will depend upon the medical community and patients accepting the therapies as safe and effective. It will also depend on our success introducing the Aurix product within the broad chronic wound market and encouraging provider evaluation and adoption of Aurix in the context of pre-existing wound treatment clinical practice.

Furthermore, the willingness of the medical community to accept or evaluate our products and processes may be impacted by the medical community’s acceptance of the quality of the clinical information that was collected and published as a result of the CED process. If the medical community and patients do not ultimately accept the therapies as safe and effective, or we are unable to raise awareness of our products and processes, our ability to sell our product may be materially and adversely affected, and the results of our operations may be adversely affected.

The Successful Commercialization of the Aurix System Will Depend on Obtaining Reimbursement from Third-Party Payors

In the U.S., the market for any pharmaceutical or biologic product is affected by the availability of reimbursement from third party payors, such as government health administration authorities, private health insurers, health maintenance organizations and pharmacy benefit management companies. If we cannot demonstrate favorable outcomes or a cost-benefit relationship, we may have difficulty obtaining adequate coverage or reimbursement for our products from these payors. Third-party payors may also deny coverage for our product if they determine that the product is experimental, unnecessary, or inappropriate. Coverage and reimbursement are often determining factors in predicting a product’s success, with some physicians and patients strongly favoring only those products for which they will be reimbursed.

The Aurix System is marketed to healthcare providers. Some of these providers, in turn, seek reimbursement from third-party payors such as Medicare, Medicaid, and other private insurers. While we have established Medicare coverage of Aurix through the NCD reconsideration, we may not be successful with our complete reimbursement strategy, including, without limitation, obtaining any additional regulatory approvals.

Should we seek to expand our commercialization internationally, we would be subject to international regulations, where the pricing of prescription pharmaceutical products and services and the level of government reimbursement may be subject to governmental control. In some countries, pricing negotiations with governmental authorities can take six to twelve months or longer after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct one or more clinical trials that compare the cost effectiveness of our product or product candidates to other available therapies. Conducting one or more of these clinical trials would be expensive and result in delays in the commercialization of our current and future products.

Managing and reducing healthcare costs has become a major priority of federal and state governments in the U.S. As a result of healthcare reform efforts, we might become subject to future regulations or other cost-control initiatives that materially restrict the price we can receive for our current and future products. Third-party payors may also limit access and reimbursement for newly approved healthcare products generally or limit the indications for which they will reimburse providers or suppliers who use any products that we may develop. Cost control initiatives could decrease the price for any products that we may develop, which would result in lower product revenues to us.

A Disruption in Healthcare Provider Networks Could Have an Adverse Effect on Operations and Profitability

Our operations and future profitability are dependent, in large part, upon the ability to contract with healthcare providers on favorable terms. In any particular service area, healthcare providers could refuse to contract with us or take other actions that could result in higher healthcare costs or create difficulties in meeting our regulatory requirements. In some service areas, certain healthcare providers may have a significant market presence. If healthcare providers refuse to contract with us, use their market position to negotiate unfavorable contracts or place us at a competitive disadvantage, our ability to market services or to be profitable in those service areas could be adversely affected. Provider networks could also be disrupted by the financial insolvency of a large healthcare provider group. Any disruption in provider networks could adversely impact our business, results of operations and financial condition.

Liquidity Problems or Bankruptcy of our Key Customers or Collaborators Could Have a Significant Adverse Effect on our Business, Financial Condition and Results of Operations

Our sales to customers are typically made on credit without collateral. There is a risk that key customers will not pay, or that payment may be delayed, because of bankruptcy, contraction of credit availability to such customers, weak sales, or other factors beyond our control, which could increase our exposure to losses from bad debts. In addition, if our key customers were to cease doing business as a result of bankruptcy or significantly reduce their orders from us, it could have a significant adverse effect on our business, financial condition, and results of operations. In addition, if our collaborators face liquidity problems or file for bankruptcy, they may choose to divert resources away from their continued cooperation and engagement with us or otherwise choose or be forced to reduce operations, which could also have a significant adverse effect on our business, financial condition, and results of operation.

We May Be Unable to Attract a Strategic Partner for the Further Development of Potential Future Product Candidates

Even if positive clinical data is eventually achieved in any future clinical trials, we may not be able to enter into strategic partnerships, licensing, or other similar arrangements that we may consider necessary or appropriate to commercialize product candidates successfully, or even have the resources necessary to seek such arrangements. Furthermore, even if such a strategic relationship regarding any of our current and future products or product candidates is reached, development milestones, clinical data, or other such benchmarks may not be achieved. Therefore, our products and product candidates may never proceed toward commercialization or drive cash infusions for us, and we may ultimately not be able to monetize the patents, existing clinical data, and other intellectual property.

Our Efforts to Secure Commercial Partners May Not Be Successful

From time to time, we may engage in discussions with larger companies regarding potential strategic partnerships involving the broad commercialization of Aurix. The resources and expertise of such a partner would greatly facilitate the capture of market share within the wound care market but would require that the economic benefits of such a broad penetration would be shared with said partner. We may not be successful in securing such a partner. Furthermore, even if a partner is secured, the partnership may not attain the market penetration contemplated, and the profits ultimately realized by us, if any, may not be sufficient to allow us to execute our business strategy.

We May Use Third-Party Collaborators and Service Providers to Help Us Support, Develop or Commercialize Our Product Candidates, and Our Ability to Commercialize Such Candidates May Be Impaired or Delayed if such Collaborations or Engagements Are Unsuccessful

We may in the future selectively pursue strategic collaborations or engagements for, among other purposes, development, data collection, analysis, and/or commercialization of our product candidates, domestically or otherwise. There can be no assurance as to our ability to utilize the data from such engagements to their potential. Nor can there be any assurance, in general, that we will be able to identify future suitable collaborators or negotiate collaboration agreements on terms that are acceptable to us or at all. In any current or future third-party collaborations, we are and would be dependent upon the success of the collaborators in performing their responsibilities and their continued cooperation and engagement. For a variety of reasons outside of our control, our collaborators or third-party providers may not cooperate with us or perform their obligations under our agreements with them. We cannot control the amount and timing of our collaborators’ resources that will be devoted to performing their responsibilities under our agreements with them. Our collaborators may choose to pursue alternative technologies in preference to those being developed in collaboration with us. The development and commercialization of our product candidates will be delayed if collaborators fail to conduct their responsibilities in a timely manner or in accordance with applicable regulatory requirements or if they breach or terminate their collaboration agreements with us. Disputes with our collaborators could also result in product development delays, decreased revenues and litigation expenses.

If We Are Unable to Maintain and Expand Our Network of Distributors, We May Not Be Able To Generate Sales.

Our operating results are directly dependent upon the sales and marketing efforts of not only our employees, but also our independent distributors. We face significant challenges and risks in managing our geographically dispersed distribution network and retaining the individuals who make up that network. If certain of our distributors were to cease to do business with us, our sales could be adversely affected. Because of the intense competition for their services, we may be unable to recruit or retain additional qualified distributors. We may not be able to enter into agreements with them on favorable or commercially reasonable terms, if at all. Failure to hire or retain qualified distributors would prevent us from maintaining or expanding our business and generating sales.

Our Limited Number of Staff May Affect our Ability to Conduct our Operations and Other Functions Effectively

Our future success depends on our ability to attract, retain, and motivate highly skilled management, scientific and sales personnel. As of December 31, 2023, we had only nine full-time employees. Our ability to maintain and provide services to our customers and our ability to provide the necessary support as part of any collaborations depends upon our ability to hire and retain business development and scientific and technical personnel with the skills necessary to keep pace with continuing changes in regenerative biological therapy technologies. Our current liquidity situation makes it unlikely that we will be able to hire additional personnel in the immediate future. Even assuming that we can resolve our immediate liquidity concerns, competition for such personnel is intense; we compete with pharmaceutical, biotechnology and healthcare companies with greater access to resources. Our inability to hire qualified personnel may lead to higher recruiting, relocation, and compensation costs for such personnel. These increased costs may make hiring new key personnel impractical.

We Are Substantially Dependent Upon Our Executive Officers

Our success substantially depends on the continued service of key management, in particular David E. Jorden, our Chief Executive and Financial Officer, and Peter Clausen, our Chief Scientific and Operating Officer. We currently do not maintain key person insurance on, Mr. Jorden or Dr. Clausen. The loss of Mr. Jorden or Dr. Clausen, or other key employees or executive officers, could adversely impact our ability to continue operations unless and until a replacement is identified.

We Rely on a Single Supplier for the Reagent Used for Aurix and an Interruption in Our Supply Chain Could Have a Material Adverse Effect on Our Business

A reagent used for our Aurix product, bovine thrombin (Thrombin JMI), is available exclusively through Pfizer. Pfizer may unilaterally raise the prices for the reagent. If a temporary or permanent interruption in the supply of the reagent were to occur, or the manufacturing costs charged by Pfizer exceed what we can reasonably afford, we would have to seek alternative sources of supply. There is no assurance we would be able to identify a suitable second source of supply or do so without significant delay. Despite our efforts to maintain an adequate supply of inventory, the loss of Pfizer, or its inability to provide us with an adequate supply of a reagent, could cause delay in the manufacture of our product, thereby impairing our ability to meet the demand of our customers and causing significant harm to our business. Any disruption of this nature or increased expense could harm our commercialization efforts and adversely affect our operating results.

We Could Be Affected by Malpractice or Product Liability Claims

Providing medical care entails an inherent risk of professional malpractice and other claims. We do not control or direct the practice of medicine by physicians or health care providers who use our product and do not assume responsibility for compliance with regulatory and other requirements directly applicable to physicians. There is no assurance that claims, suits, or complaints relating to the use of our products, and treatment administered by physicians, will not be asserted against us in the future. The production, marketing and sale, and use of our product entails risks that product liability claims will be asserted against us. These risks cannot be eliminated, and we could be held liable for any damages that result from adverse reactions or infectious disease transmission. Such liability could materially and adversely affect our business, prospects, operating results, and financial condition. We currently maintain professional and product liability insurance coverage, but the coverage limits of this insurance may not be adequate to protect against all potential claims. We may not be able to obtain or maintain professional and product liability insurance in the future on acceptable terms or with adequate coverage against potential liabilities.

Our Product Has Existing Competition in the Marketplace and We May Not Be Able to Compete Effectively.

In the market for biotechnology products, we face competition from pharmaceutical companies, biopharmaceutical companies, medical device companies, and other competitors. The chronic wound market has many therapies that compete with Aurix that have established habitual use patterns and provider contracts to encourage standardized use. Furthermore, other companies have developed or are developing products that could be in direct future competition with our current product line. Biotechnology development projects are characterized by intense competition. Thus, we may not be the first to market with any newly developed products and we may not successfully be able to market these products. If we are not able to participate and compete in the regenerative biological therapy market, our financial condition will be materially and adversely affected. We may not be able to compete effectively against such companies in the future. Many of these companies have substantially greater capital resources, larger marketing staffs and more experience in commercializing products than we do. Recently developed technologies, or technologies that may be developed in the future, may be the basis for developments that will compete with our current and future products.

Risks Related to Government Regulations

Our Product Is Subject to Governmental Regulation

Our success is also impacted by factors outside of our control. Our current technology and products are subject to extensive regulation by numerous governmental authorities in the U.S., both federal and state, and in foreign countries by various regulatory agencies. Specifically, our product is subject to regulation by the U.S. Food and Drug Administration, or FDA, and state regulatory agencies. The FDA regulates drugs, medical devices, and biologics that move in interstate commerce and requires that such products receive clearance or pre-marketing approval based on evidence of safety and efficacy. The regulations of government health ministries in foreign countries are analogous to those of the FDA in both application and scope. In addition, any change in current regulatory interpretations by, or the positions of, state regulatory officials where our product is used could materially and adversely affect our ability to sell our product in those states. The FDA will require us to obtain clearance or approval of new or modified devices when used for treating specific wounds or marketed with specific wound-healing claims, or for other products under development.

We believe our current product for sale is legally marketed. As we expand and offer and/or develop additional products in the U.S. and in foreign countries, clearance or approval from the FDA and comparable foreign regulatory authorities prior to introduction of any such products into the market may be required. We provide no assurance that we will be able to obtain all necessary approvals from the FDA or comparable regulatory authorities in foreign countries for these products. Failure to obtain the required approvals would have a material adverse impact on our business and financial condition.

Compliance with FDA and other governmental requirements imposes significant costs and expenses. Further, our failure to comply with these requirements could result in sanctions, limitations on promotional or other business activities, or other adverse effects on our business. Further, recent efforts to control healthcare costs could negatively affect demand for our current and future products and services.

We Must Comply with the Physician Payment Sunshine Act

We are required to comply with the United States Physician Payment Sunshine Act, which requires certain manufacturers of drugs, medical devices, biologicals, and medical supplies that participate in U.S. federal healthcare programs to report certain payments and items of value given to physicians and teaching hospitals. Manufacturers are required to report this information annually to CMS. Manufacturers are required to report aggregate payment data to CMS by the 90th day of each subsequent calendar year. We cannot assure you that we will collect and report all data timely and accurately. If we fail to accurately and timely report this information, we could suffer severe penalties.

Any applicable manufacturer that fails to timely, accurately, or completely report the information required in accordance with the rules of the Sunshine Act is subject to a civil monetary penalty of not less than $1,000, but not more than $10,000, for each payment or other transfer of value or ownership or investment interest not reported timely, accurately, or completely (up to $150,000). For “knowing” failures to report, the penalties increase to not less than $10,000, but not more than $100,000, for each such failure (up to $1,000,000). The amount of civil monetary penalties imposed on each applicable manufacturer or applicable group purchasing organization is aggregated separately. Subject to separate aggregate totals, the maximum combined annual total is $1,150,000.

Several of the U.S. states have parallel reporting laws, sometimes accompanied with “gift bans” prohibiting manufacturers from making gifts or other remunerations to prescribers. Massachusetts and Vermont are two such states. There are various penalties associated with noncompliance with the state laws, as well.

Legislative and Administrative Action May Have an Adverse Effect on the Company

Political, economic, and regulatory influences are subjecting the health care industry in the U.S. to fundamental change. We cannot predict what other legislation relating to our business or to the health care industry may be enacted, including legislation relating to third-party reimbursement, or what effect such legislation may have on our business, prospects, operating results and financial condition. We expect federal and state legislators to continue to review and assess alternative health care delivery and payment systems, and possibly adopt legislation affecting further changes in the health care delivery system. Such laws may contain provisions that may change the operating environment for hospitals and managed care organizations. Health care industry participants may react to such legislation by curtailing or deferring expenditures and initiatives, including those relating to our current and future products. Future legislation could result in modifications to the existing public and private health care insurance systems that would have a material adverse effect on the reimbursement policies discussed above. With growing pressures on government budgets, government efforts to contain or reduce health care spending in some way or another are likely to continue. Any measures to restrict health care spending could result in decreased revenue from products and decrease potential returns from any future research and development initiatives. Furthermore, we may not be able to successfully neutralize any lobbying efforts against any initiatives we may have with governmental agencies. In addition to legislative initiatives, we may be subject to changes in current regulations and policies affecting coverage and reimbursement for our current and future products. Administrative agencies such as the Centers for Medicare and Medicaid Services have broad discretion to adopt or modify polices through rulemaking, and adoption of rules that curtail access to our products or limit reimbursement could have a material adverse effect on the adoption of our current and future products by health care providers, which would have a material adverse effect on our business.

Failure to Obtain Regulatory Approval in International Jurisdictions Would Prevent Us from Marketing Our Product Abroad

We may in the future seek to market some of our product candidates outside the U.S. In order to market our product candidates in the European Union and many other jurisdictions, we must submit clinical data concerning our product candidates and obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval from foreign regulators may be longer than the time required to obtain FDA approval. The regulatory approval process outside the U.S. may include all of the risks associated with obtaining FDA approval. In addition, in many countries outside the U.S., it is required that the product candidate be approved for reimbursement before it can be approved for sale in that country. In some cases, this may include approval of the price we intend to charge for our product, if approved. We may not obtain approvals from regulatory authorities outside the U.S. on a timely basis, or at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the U.S. does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA, but a failure or delay in obtaining regulatory approval in one country may negatively affect the regulatory process in other countries. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize any products in any market and therefore may not be able to generate sufficient revenues to support our business.

Risks Related to Our Intellectual Property and Cybersecurity

Our Intellectual Property Assets Are Critical to Our Success

We regard our trademarks, trade secrets and other intellectual property assets as critical to our success. We rely on a combination of trademarks, and trade secret and copyright laws, as well as confidentiality procedures, contractual provisions, and other similar measures, to establish and protect our intellectual property. We attempt to prevent disclosure of our trade secrets by restricting access to sensitive information and requiring employees, consultants, and other persons with access to our sensitive information to sign confidentiality agreements. Despite these efforts, we may not be able to prevent misappropriation of our technology or deter others from developing similar technology in the future. Furthermore, policing the unauthorized use of our intellectual property assets is difficult and expensive. Litigation could result in substantial costs and diversion of resources. We can provide no assurance that we will be successful in any litigation matter relating to our intellectual property assets. Any misappropriation of our intellectual property assets could have a material adverse effect on our ability to increase sales of our commercial product and/or continue the development of any future pipeline candidates.

If We Are Unable to Protect the Confidentiality of Our Proprietary Information and Know-how, Our Competitive Position Would Be Impaired

A significant amount of our technology, especially regarding manufacturing processes, is unpatented and is maintained by us as trade secrets. The background technologies used in the development of our product candidates are known in the scientific community, and it is possible to duplicate the methods we use to create our product candidates. In an effort to protect these trade secrets, we require our employees, consultants and contractors to execute confidentiality agreements with us. These agreements require that all confidential information developed by the individual or made known to the individual by us during the individual’s relationship with us be kept confidential and not disclosed to third parties. These agreements, however, may not provide us with adequate protection against improper use or disclosure of confidential information, and these agreements may be breached. Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. A breach of confidentiality could affect our competitive position. In addition, in some situations, these agreements may conflict with, or be subject to, the rights of third parties with whom our employees, consultants, collaborators or advisors have previous employment or consulting relationships. Also, others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets. The disclosure of our trade secrets would impair our competitive position.

If We Infringe, or Are Alleged to Infringe, Intellectual Property Rights of Third Parties, Our Business Could Be Harmed

Our research, development, and commercialization activities, including any product candidates resulting from these activities, may infringe, or be claimed to infringe, patents or other proprietary rights owned by third parties, and to which we do not hold licenses or other rights. There may be patent applications owned by third parties that have been filed but not published that, when issued, could be asserted against us. These third parties could bring claims against us that would cause us to incur substantial expenses and, if successful against us, could cause us to pay substantial damages.

Further, if a patent infringement suit were brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of the suit. We have not conducted an exhaustive search or analysis of third-party patent rights to determine whether our research, development, or commercialization activities, including any product candidates resulting from these activities, may infringe or be alleged to infringe any third-party patent rights. As a result of intellectual property infringement claims, or in order to avoid potential claims, we may choose or be required to seek a license from the third party. These licenses may not be available on acceptable terms, or at all. Even if we are able to obtain a license, the licensee would likely obligate us to pay license fees or royalties or both, and the rights granted to us might be nonexclusive, which could result in our competitors gaining access to the same intellectual property.

Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms. All of the issues described above could also affect our potential collaborators to the extent we have any collaborations then in place, which would also affect the success of the collaboration and therefore us. There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical and biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other proceedings, including inter partes review and/or interference proceedings declared by the U. S. Patent and Trademark Office and opposition proceedings in the European Patent Office, regarding intellectual property rights with respect to our product candidates and technology.

Our Business May Be Adversely Impacted by Information Systems Failures or Data Breaches

We rely on information systems to process transactions, communicate with customers, manage our business, and process and maintain data and other information. We are not aware of any material losses to our business or results of operations due to information system failures, data breaches, or cybersecurity incidents. However, threats to information systems are evolving and disruptions can be caused by a variety of events, such as viruses, malicious malware, unauthorized access attempts to data, or other types of cybersecurity incidents. Such events could produce disruptions that result in an unexpected delay in operations, loss of confidential or otherwise protected information, corruption of data, and expenses related to the repair or replacement of our computer systems. We cannot be certain that our information system and cybersecurity protocols are sufficient to withstand a cybersecurity incident. The inability to maintain proper function, security, and availability of our information systems and the data maintained in those systems could interrupt our operations and could result in loss of sales or legal or regulatory claims which could adversely affect our revenues and profits or damage our reputation. We also rely on numerous third-party providers for information technology services, and we face similar risks relating to these providers. While our general insurance coverage may, subject to policy terms and conditions including deductibles, cover specific aspects of information systems and cybersecurity risks, such insurance coverage may be insufficient to cover all losses. As information system and cybersecurity risks continue to evolve, we may be required to expend additional resources to continue to enhance our information system and cybersecurity measures and to investigate and remediate any information system and cybersecurity vulnerabilities.

Data Privacy Security Failures or Breaches Could Expose Us to Regulatory and Other Liability.

We are subject to various federal and state laws governing privacy and security of personally identifiable information. Despite safeguards by us, a data privacy security failure or breach could occur as a result of unintentional or deliberate acts to obtain unauthorized access to information, or to destroy, manipulate, or sabotage data. Information system threats, failures breaches, or incidents also could result in the loss or release of personally identifiable information. A privacy or cybersecurity failure or breach could cause a loss of business, regulatory enforcement, substantial legal liability, and reputational harm. Further, the adoption of new privacy and cybersecurity laws at the federal and state level could require us to incur significant compliance costs.

Risks Related to Our Common Stock

A Retail Trading Market for Our Common Stock May Not Actively Develop.

Shares of our common stock currently resumed trading on the OTCQB on August 22, 2022. Prior to then, due to a prior lack of current and publicly available information about the Company, trading in shares of our common stock was eligible only for unsolicited quotes on the “Expert Market” of the OTC Markets Group. Because quotations in Expert Market securities are restricted from public viewing, the designation severely limits the number of buyers of, and effectively prevents the development of an active trading market in, designated securities. Even though shares of our common stock now trade on the OTCQB, there can be no assurance as to whether OTC Markets Group will continue to enable shares of our common stock to be quoted on a retail market or whether shares of our common stock can successfully be traded on other trading platforms. As a result, any limited trading of shares of our common stock subject to having a higher risk of wider spreads, increased volatility, and price dislocations.

Trading on an Over-the-Counter Market Could Adversely Affect the Liquidity of Our Common Stock.

Trading in our common stock on the OTCQB since August 22, 2022 has been very limited and we cannot make any assurances that the trading volume will increase, or, if and when it increases, that it will be sustained at any level. Over-the-counter markets are generally considered to be less efficient than, and not as broad as, a stock exchange. Stockholders may have difficulties reselling significant numbers of shares of common stock at any particular time and may not be able to resell their shares of common stock at or above the price paid for such shares. As a result, stockholders may be required to hold shares of common stock for an indefinite period of time. In addition, sales of substantial amounts of common stock could lower the prevailing market price of our common stock.

U.S. Broker-Dealers May Be Discouraged from Effecting Transactions in Shares of our Common Stock.

Our Common Stock may be deemed a “penny stock” under SEC rules. As a result, trading in our common stock may be subject to the requirements of SEC rules that require additional disclosure by broker-dealers in connection with any trades involving a stock defined as a penny stock (generally, any non-exchange listed equity security that has a market price share of less than $5.00 per share, subject to certain exceptions) and a two business day “cooling off period” before broker and dealers can effect transactions in penny stocks. For these types of transactions, the broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transaction before the sale. The broker-dealer also must disclose the commissions payable to the broker-dealer, current bid and offer quotations for the penny stock and, if the broker-dealer is the sole market-maker, the broker-dealer must disclose this fact and the broker-dealer’s presumed control over the market. These, and the other burdens imposed upon broker-dealers by the penny stock requirements, could discourage broker-dealers from effecting transactions in our common stock, which could severely limit the market liquidity of our common stock and the ability of holders of our common stock to sell it.

The Compliance and Reporting Requirements of Being a Public Reporting Company Can Be Expensive.

We are a public reporting company and, accordingly, are subject to the information and reporting requirements of the Exchange Act, and other federal securities laws, including compliance with the Sarbanes-Oxley Act. Preparing and filing annual and quarterly reports, proxy statements and other information with the SEC and furnishing audited reports to stockholders is costly. In addition, we may face time consuming and costly effects to develop and implement internal controls and reporting procedures required by the Sarbanes-Oxley Act.

Our Officers, Directors and Principal Stockholders Can Exert Significant Influence Over Us and May Make Decisions That Are Not in the Best Interests of All Stockholders

As of March 15, 2024, our officers and directors beneficially owned approximately 21.1% of our shares of common stock, while four other principal stockholders beneficially owned in the aggregate an additional approximately 47.0% of our shares of common stock. As a result, our officers, directors, and certain principal holders of common stock are able to affect the outcome of, or exert significant influence over, all matters requiring stockholder approval, including the election and removal of directors. This concentration of ownership of our common stock could have the effect of delaying or preventing a change of control of us or otherwise discouraging or preventing a potential acquirer from attempting to obtain control of us. This, in turn, could have a negative effect on the market price of our common stock, if and when it commences trading. It could also prevent our stockholders from realizing a premium over the market prices for their shares of common stock. Moreover, the interests of this concentration of ownership may not always coincide with our interests or the interests of other stockholders, and accordingly, they could cause us to enter into transactions or agreements that we would not otherwise consider.

Transactions Engaged in by Our Largest Stockholders, Our Directors or Officers Involving Our Common Stock May Have an Adverse Effect on the Value of Our Common Stock

Sales of our common stock by our officers, directors and principal stockholders could have the effect of lowering the price or value of our common stock. The perceived risk associated with the possible sale of a large number of shares of common stock by those stockholders could cause some of our stockholders to sell their stock, thus adversely affecting the value of our common. Our largest stockholders, directors and executive officers may sell a significant number of shares for a variety of reasons unrelated to the performance of our business. Our stockholders may perceive these sales as a reflection of management’s view of the business, which may result in some stockholders selling their shares of our common stock. These sales also could adversely affect the value of our common stock.

Volatility of Our Stock Price Could Adversely Affect Current and Future Stockholders

The market price of our common stock is likely to fluctuate widely in response to various factors which are beyond our control. The price of our common stock is not necessarily indicative of our operating performance or long-term business prospects. In addition, the securities markets have from time-to-time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock. Factors that could cause the market price to fluctuate substantially include, among others:

• our ability or inability to execute our business plan;
• the dilutive effect or perceived dilutive effect of additional equity financings;
• investor perception of our company and of the industry;
• the success of competitive products or technologies;
• regulatory developments in the U.S. or overseas;
• developments or disputes concerning patents or other proprietary rights;
• the recruitment or departure of key personnel; or
• general economic, political and market conditions.

The stock market in general can often experience extreme price and volume fluctuations. Any such market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility could be worse if the trading volume of our common stock is low.

Our management recognizes the importance of assessing, identifying, and managing material risks associated with cybersecurity threats. These risks include, among other things: operational risks, intellectual property theft, fraud, extortion, harm to employees or customers, and violation of data privacy or similar security laws.

We have implemented an information security management system in accordance with our risk profile and business that is designed to protect the Company from cybersecurity threats. As our business operations grow, we plan to develop a more robust and detailed strategy for cybersecurity in alignment with nationally accepted standards.

We have not identified any cybersecurity incidents or threats that have materially affected us or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition. However, like other companies in our industry, we and our third-party vendors have from time-to-time experienced threats and cybersecurity incidents that could affect our information or systems,

The Board of Directors and Audit Committee oversee the management of risks by the Company’s management. The Audit Committee is responsible for reviewing the Company’s cybersecurity program and risks, as identified by our management, and the steps that our management has taken to protect against threats to the Company’s assets including information systems and data security.

Our principal executive offices are located in a leased space at 8285 El Rio Street, Suite 190, Houston, TX 77054.

The Company does not own any real property and does not intend to invest in any real property in the foreseeable future.

There are currently no claims or actions pending against us, the ultimate disposition of which could have a material adverse effect on our results of operations, financial condition, or cash flows.

The following discussion and analysis of the Company’s financial condition and results of operations should be read in conjunction with the financial statements and related notes appearing elsewhere in this Annual Report. The discussion in this section regarding the Company’s business and operations includes “forward-looking statements”. See “Special Note Regarding Forward-Looking Statements” at the beginning of this Annual Report.

The use of autologous (i.e., from self or the patient’s own) biological therapies for tissue repair and regeneration is part of a transformative clinical strategy designed to improve long term recovery in complex chronic conditions with significant unmet medical needs.

Our only current commercial offering consists of point of care technology for the safe and effective separation of autologous blood to produce a platelet-based therapy for the chronic wound care market (the "Aurix System"). The Company ceased normal operating activities effective May 1, 2019, as it awaited developments concerning Medicare coverage of the Aurix System under its National Coverage Decision (“NCD”) reconsideration request. Product sales were reinitiated in mid-2022 after the favorable NCD determination was issued in April 2021, the Aurix System supply chain was re-established, and equity capital was accessed in December 2021 via the early exercise of warrants under a warrant modification agreement.

The revenue amounts presented in these comparison sections are rounded to the nearest thousand.

Comparison of the Years Ended December 31, 2023 and 2022

Revenue and Gross Profit

Product revenues for the year ended December 31, 2023 totaled approximately $610,000 with approximately $482,000 of associated gross profit and a resulting gross margin of approximately 79%. Product revenues for the year ended December 31, 2022 totaled approximately 112,000 as re-initiation of commercial sales activity for the Aurix product began during the three months ended September 30, 2022. Gross profit for the year ended December 31, 2022 was approximately $93,000 and a resulting gross margin of 83%.

Operating Expenses

Total operating expenses increased approximately $237,000 to approximately $3,650,000 comparing the year ended December 31, 2023 to the prior full year 2022 period. The increase was attributable to increases of (i) approximately $274,000 in compensation and benefits expense as employee headcount was not constant for the two years and employees were added during the 2022 period in preparation for re-commercialization, (ii) approximately $90,000 of distributor commissions due to increased revenues, and (iii) $160,000 bad debt provision. These increases were partially offset by a decrease of approximately $277,000 in third-party professional fees.

Interest Expense, net

Interest expense, net for the years ended December 31, 2023 and December 31, 2022 of approximately $3,200 and $2,100, respectively, represents interest expense from the financing of insurance premiums.

Other Income (Expense)

Other income for the year ended December 31, 2022 primarily represents the gain of approximately $146,000 realized from the negotiated settlement of legacy accounts payable with third-party vendors including the full release of any ongoing payment liability.

Liquidity and Capital Resources

Overview

As of December 31, 2023, we had cash and cash equivalents of approximately $0.9 million, total current assets of approximately $1.6 million and total current liabilities of approximately $0.7 million. We have a history of losses and are not currently profitable. For the years ended December 31, 2023 and 2022, we incurred net losses of approximately $3.2 million in each year. As of December 31, 2023, our accumulated deficit was approximately $29.9 million and our stockholders’ equity was approximately $1.0 million.

We maintain our cash deposits primarily in financial institutions, which may at times exceed amounts covered by insurance provided by the U.S. Federal Deposit Insurance Corporation (“FDIC”). We have not experienced any losses related to amounts in excess of FDIC limits.

Financing Activities

In 2022, we sold 3,957,757 shares of common stock to certain accredited investors pursuant to Securities Purchase Agreements in two private placements which closed in April and May 2022 for proceeds of $3,957,757.

Additionally, in August 2022, we entered into a Common Stock and Warrant Purchase Agreement with Pacific Medical, Inc. (“Pacific Med”) for the sale and issuance of shares of common stock and warrants to purchase shares of common stock. Pursuant to the Common Stock and Warrant Purchase Agreement, Pacific Med purchased 500,000 shares of the Company’s common stock for $500,000 in September 2022.

In 2023, we sold 2,442,500 shares of common stock to certain accredited investors pursuant to Securities Purchase Agreements in two private placements which closed in August and December 2023 for proceeds of $1,997,500.

Additionally, effective January 1, 2024, pursuant to the provisions of the August 2022 Common Stock and Warrant Purchase Agreement described above, we issued to Pacific Med a warrant to purchase up to 500,000 shares of common stock at a price equal to the lower of $2.00 per share or $0.56, the 20-day volume weighted average closing price per share of our common stock ending December 31, 2023. The warrant is exercisable until June 30, 2024.

Going Concern

Our continuing losses and limited cash resources raise substantial doubt about our ability to continue as a going concern, and we need to raise substantial additional funds in order to continue to conduct our business. If we are unable to secure sufficient capital to fund our operating activities, we may be forced to delay further the completion of, or significantly reduce the scope of, our current business plan. It is uncertain whether we will be able to obtain such financing on satisfactory terms or at all. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We may not be able to obtain additional capital as required to finance our efforts, through equity or debt financing or any combination thereof, on satisfactory terms or at all. Additionally, any such financing, if at all obtained, may not be adequate to meet our capital needs and to support our operations.

Cash Flows

Net cash provided by (used in) operating, investing, and financing activities for the periods presented were as follows:

Critical Accounting Policies

This Management's Discussion and Analysis of Financial Condition and Results of Operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. A summary of our significant accounting policies is included in Note 2 to the accompanying consolidated financial statements.

A “critical accounting policy” is one that is both important to the portrayal of our financial condition and results of operations and that requires management’s most difficult, subjective, or complex judgments. Such judgments are often the result of a need to make estimates about the effect of matters that are inherently uncertain. We have identified the following accounting policies as critical:

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, recoverability and depreciable lives of long-lived assets, deferred taxes and associated valuation allowance, and allowances for inventory obsolescence and doubtful accounts. Actual results could differ from those estimates.

Revenue Recognition

We analyze our revenue arrangements to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers; (ii) identification of distinct performance obligations in the contract; (iii) determination of contract transaction price; (iv) allocation of contract transaction price to the performance obligations; and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation. We recognize revenues upon the satisfaction of its performance obligations (upon transfer of control of promised goods or services to customers) in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

We provide for the sale of our products, including disposable processing sets and supplies to customers. Revenue from the sale of products is recognized upon shipment of products to the customers. We do not maintain a reserve for returned products, as in the past those returns have not been material and are not expected to be material in the future.

Stock-Based Compensation

We recognize expense in the consolidated statements of operations for the fair value of all stock-based compensation to key employees, non-employee directors and advisors, generally in the form of stock options and stock awards. We use the Black-Scholes option valuation model to estimate the fair value of stock options on the grant date. Compensation cost is amortized on a straight-line basis over the vesting period for each respective award. We account for any forfeitures as they occur.

Basic and Diluted Earnings (Loss) per Share

In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive.

For periods of net income, diluted earnings per share is computed using the more dilutive of the “treasury method” or “two class method.” Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted- average number of shares outstanding plus the dilutive impact of all potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method, and convertible notes using the if-converted method. Because none of the Company’s equity-linked financial instruments contain non-forfeitable rights to dividends, the “two class” method results in the same diluted earnings per share as the “treasury method.”

Recent Accounting Pronouncements Not Yet Adopted

The Company does not believe that any recently issued effective standards, or standards issued but not yet effective, if adopted, would have a material effect on the accompanying consolidated financial statements.

Disclosure Controls and Procedures

Under the supervision of and with the participation of our management, including our Chief Executive Officer, who is our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Form 10-K. The term “disclosure controls and procedures,” as set forth in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this Form 10-K, we concluded that, as of such dates, our disclosure controls and procedures were not effective due to the existence of the material weaknesses in the Company’s internal control over financial reporting described below under “Material Weaknesses” and “Remediation Plan.”

Notwithstanding the conclusion that our disclosure controls and procedures as of the end of the period covered by this Form 10-K were not effective, and notwithstanding the material weaknesses in our internal control over financial reporting described below, management believes that the consolidated financial statements and related financial information included in this Form 10-K fairly present in all material respects our financial condition, results of operations and cash flows as of the dates presented, and for the periods ended on such dates, in conformity with GAAP.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Our management conducted an assessment of our internal control over financial reporting as set forth in Item 308(a) of Regulation S-K promulgated under the Exchange Act and Section 404 of the Sarbanes-Oxley Act as of the end of the end of the period covered by this Form 10-K. Based on this assessment, our management concluded that our internal control over financial reporting was ineffective due to the continuing material weakness in our internal control over financial reporting described below under “Material Weaknesses” and “Remediation Plan.”

Material Weaknesses

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. In connection with the preparation of this Form 10-K and the consolidated financial statements and related disclosures herein, management identified the following material weaknesses.

Beginning in mid-2019, we ceased ongoing operational activities and terminated all our financial accounting and reporting resources as we worked to reach a favorable outcome to Medicare reimbursement coverage for the Aurix System. When we re-started commercial operations in 2022 and as disclosed in Annual Report on Form 10-K for the fiscal year ended December 31, 2022, the Company had not hired and did not maintain a sufficient complement of accounting and financial reporting resources. The lack of sufficient accounting and financial reporting resources also prevented the Company from maintaining appropriately designed, and monitoring the effectiveness of, internal control over financial reporting.

Remediation Plan

Beginning in 2022, the Company engaged outside consultants to assist with various accounting and financial reporting matters and will continue assessing the need for hiring additional internal accounting and third-party financial reporting resources. As we continue to obtain additional financial resources and as we continue to increase our operating activity, management, under the oversight of the Audit Committee of the Board of Directors, will continue to implement measures designed to improve our internal control over financial reporting to remediate the identified material weaknesses, namely, to identify and engage, through internal hiring and the use of external third parties, a sufficient complement of accounting and financial reporting resources and to periodically assess the design and operating effectiveness of our internal controls.

While we believe that these efforts will improve our internal control over financial reporting, the implementation of these measures is ongoing and will continue to require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles. We cannot assure you that the measures we have taken to date, or that we may take in the future, will be sufficient to remediate the material weaknesses we have identified or avoid potential future material weaknesses.

Changes in Internal Control over Financial Reporting

Other than as described above, there were no changes in our internal control over financial reporting during the year ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
