Overview

Celcuity is a clinical-stage biotechnology company focused on the development of targeted therapies for oncology. The Company’s lead therapeutic candidate is gedatolisib, a pan-PI3K/mTOR inhibitor. Its mechanism of action and pharmacokinetic properties are highly differentiated from other currently approved and investigational therapies that target PI3K or mTOR alone or together. The Company initiated VIKTORIA-1, a Phase 3 study evaluating gedatolisib in patients with HR+/HER2- advanced breast cancer in 2022 and is currently enrolling patients. In addition to the Phase 3 study, the Company recently announced that it received U.S. Food and Drug Administration (“FDA”) clearance for its Investigational New Drug (IND) submission for the clinical development of gedatolisib in combination with Nubeqa® (darolutamide), for the treatment of patients with metastatic castration resistant prostate cancer (mCRPC). The Company initiated a Phase 1b/2 study, CELC-G-201, in the first quarter of 2024 and is currently enrolling patients. Its CELsignia companion diagnostic platform is uniquely able to analyze live patient tumor cells to identify new groups of cancer patients likely to benefit from already approved targeted therapies.

Gedatolisib, is a potent, well-tolerated, small molecule reversible dual inhibitor, administered intravenously, that selectively targets all Class I isoforms of PI3K and mammalian target of rapamycin (mTOR). In April 2021, we obtained exclusive global development and commercialization rights to gedatolisib under a license agreement with Pfizer, Inc. We believe gedatolisib’s unique mechanism of action, differentiated chemical structure, favorable pharmacokinetic properties, and intravenous formulation offer distinct advantages over currently approved and investigational therapies that target PI3K or mTOR alone or together.

• Overcomes limitations of therapies that only inhibit a single Class I PI3K isoform or only one mTOR kinase complex.

Gedatolisib is a pan-class I isoform PI3K inhibitor with low nanomolar potency for the p110α, p110β, p110γ, and p110δ isoforms and mTORC1 and mTORC2 complexes. Each PI3K isoform and mTOR complex is known to preferentially affect different signal transduction events that involve tumor cell survival, depending upon the aberrations associated with the linked pathway. When a therapy only inhibits a single Class 1 isoform (e.g., alpelisib, a PI3K-α inhibitor ) or only one mTOR kinase complex (e.g., everolimus, an mTORC1 inhibitor), numerous feedforward and feedback loops between the PI3K isoforms and mTOR complexes cross-activate the uninhibited sub-units. This, in turn, induces compensatory resistance that can reduce the efficacy of isoform specific PI3K or single mTOR kinase complex inhibitors. Inhibiting all four PI3K isoforms and both mTOR complexes, as gedatolisib does, thus prevents the confounding effect of isoform interaction that may occur with isoform-specific PI3K inhibitors and the confounding interaction between PI3K isoforms and mTOR.

• Better tolerated by patients than oral PI3K and mTOR drugs.

Gedatolisib is administered intravenously (IV) on a four-week cycle of three weeks-on, one week-off, in contrast to the orally administered pan-PI3K or dual PI3K/mTOR inhibitors that are no longer being clinically developed. Oral pan-PI3K or PI3K/mTOR inhibitors have repeatably been found to induce significant side effects that were not well tolerated by patients. This typically leads to a high proportion of patients requiring dose reductions or treatment discontinuation. The challenging toxicity profile of these drug candidates ultimately played a significant role in the decisions to halt their development, despite showing promising efficacy. By contrast, gedatolisib stabilizes at lower concentration levels in plasma compared to orally administered PI3K inhibitors, resulting in less toxicity, while maintaining concentrations sufficient to inhibit PI3K/mTOR signaling.

Isoform-specific PI3K inhibitors administered orally were developed to reduce toxicities in patients. While the range of toxicities associated with isoform-specific inhibitors is narrower than oral pan-PI3K or PI3K/mTOR inhibitors, administering them orally on a continuous basis still leads to challenging toxicities. The experience with an FDA approved oral p110-α specific inhibitor, Piqray, illustrates the challenge. In its Phase 3 pivotal trial Piqray was found to induce a Grade 3 or 4 adverse event (AE) related to hyperglycemia in 39% of patients evaluated. In addition, 26% of patients discontinued alpelisib due to treatment related adverse events. By contrast, in the 103-patient dose expansion portion of the Phase 1b clinical trial with gedatolisib, only 7% of patients experienced Grade 3 or 4 hyperglycemia and less than 10% discontinued treatment.

As of March 31, 2024, 492 patients with solid tumors have received gedatolisib in eight clinical trials sponsored by Pfizer. Of the 492 patients, 129 were treated with gedatolisib as a single agent in three clinical trials. The remaining 363 patients received gedatolisib in combination with other anti-cancer agents in five clinical trials. Additional patients received gedatolisib in combination with other anti-cancer agents in nine investigator sponsored clinical trials.

A Phase 1b trial (B2151009) evaluating patients with HR+/HER2- metastatic breast cancer was initiated in 2016 and subsequently enrolled 138 patients. Four patients from this study continue to receive study treatment, as of March 31, 2024, each of whom have received study treatment for more than five years. The B2151009 clinical was an open label, multiple arm Phase 1b study that evaluated gedatolisib in combination with palbociclib (CDK4/6 inhibitor) and fulvestrant or letrozole in patients with HR+/HER2- advanced breast cancer. Thirty-five patients were enrolled in two dose escalation arms to evaluate the safety and tolerability and to determine the maximum tolerated dose (MTD) of gedatolisib when used in combination with the standard doses of palbociclib and endocrine therapy (letrozole or fulvestrant). The MTD was determined to be 180 mg administered intravenously once weekly. A total of 103 patients were subsequently enrolled in one of four expansion arms (A, B, C, D).

High objective overall response rates (ORR) were observed in all four expansion arms and were comparable in each arm for PIK3CA WT and PIK3CA MT patients. As of the data cut-off date, March 16, 2023, for treatment- naïve patients in Escalation Arm A and Expansion Arm A (n=41), median progression free survival (mPFS) was 48.6 months, median duration of response (mDOR) was 46.9 months, and ORR was 79%, respectively. This data compares favorably to published data for current first-line standard-of-care treatments for patients with HR+/HER2-advanced breast cancer. In patients who received prior hormonal therapy alone or in combination with a CDK4/6 inhibitor (Arms B, C, and D), ORR (including unconfirmed partial responses) ranged from 36% to 77%. Each arm achieved its primary endpoint target, which was reporting higher ORR in the study arm than ORR from either the PALOMA-2 (ORR=55%) study that evaluated palbociclib plus letrozole for Arm A or the PALOMA-3 study (ORR=25%) that evaluated palbociclib plus fulvestrant for Arms B, C, and D. For all enrolled patients, a clinical benefit rate (CBR) of ≥ 79% was observed. Median progression-free survival (PFS)was 12.9 months for patients who received a prior CDK4/6 inhibitor and were treated in the study with the Phase 3 dosing schedule (Arm D).

Gedatolisib combined with palbociclib and endocrine therapy demonstrated a favorable safety profile with manageable toxicity. The majority of treatment emergent adverse events were Grade 1 and 2. The most frequently observed adverse events included stomatitis/mucosal inflammation, the majority of which were Grade 1 and 2. The most common Grade 4 AEs were neutropenia and neutrophil count decrease, which were assessed as related to treatment with palbociclib. No grade 5 events were reported in this study.

We are currently enrolling patients in a Phase 3, open-label, randomized clinical trial (VIKTORIA-1) to evaluate the efficacy and safety of two regimens in adults with HR+/HER2- advanced breast cancer whose disease has progressed after prior CDK4/6 therapy in combination with an aromatase inhibitor: 1) gedatolisib in combination with palbociclib and fulvestrant; and 2) gedatolisib in combination with fulvestrant. Approximately two hundred clinical sites in North America, Europe, South America, Asia, and Australia have been selected to participate in the study. The first clinical site was activated in the third quarter of 2022, and the first patient was dosed in December 2022.

The VIKTORIA-1 clinical trial will enable separate evaluation of subjects according to their PIK3CA status. Subjects who meet eligibility criteria and are PIK3CA WT will be randomly assigned (1:1:1) to receive a regimen of either gedatolisib, palbociclib, and fulvestrant (Arm A), gedatolisib and fulvestrant (Arm B), or fulvestrant (Arm C). Subjects who meet eligibility criteria and are PIK3CA MT will be randomly assigned (3:3:1) to receive a regimen of either gedatolisib, palbociclib, and fulvestrant (Arm D) or alpelisib and fulvestrant (Arm E), or gedatolisib and fulvestrant (Arm F).

We received approval from the FDA in mid-2023 to proceed with the clinical development of gedatolisib in combination with Nubeqa® (darolutamide), an approved androgen receptor inhibitor, for the treatment of patients with mCRPC. We have since initiated a Phase 1b/2 study (CELC-G-201) that will enroll up to 54 participants with mCRPC who progressed after treatment with an androgen receptor inhibitor. We dosed our first patient in this trial in February 2024.

In the Phase 1b portion of the study, Celcuity expects that 36 participants will be randomly assigned to receive 600 mg darolutamide combined with either 120 mg gedatolisib in Arm 1 or 180 mg gedatolisib in Arm 2. An additional 12 participants will then be enrolled in the Phase 2 portion of the study at the recommended phase 2 dose (RP2D) level to enable evaluation of 30 participants treated with the RP2D of gedatolisib.

The primary objectives of the Phase 1b portion of the trial include assessment of the safety and tolerability of gedatolisib in combination with darolutamide and determination of the recommended Phase 2 dose of gedatolisib. The primary objective of the Phase 2 portion of the trial is to assess the radiographic progression-free survival (rPFS) at six months of patients who received the RP2D.

Our proprietary CELsignia diagnostic platform is the only commercially ready technology we are aware of that uses a patient’s living tumor cells to identify the specific abnormal cellular process driving a patient’s cancer and the targeted therapy that best treats it. This enables us to identify patients whose tumors may respond to a targeted therapy, even though they lack a previously associated molecular mutation. By identifying cancer patients whose tumors lack an associated genetic mutation but have abnormal cellular activity a matching targeted therapeutic is designed to inhibit, CELsignia CDx can expand the markets for a number of already approved targeted therapies. Our current CDx identifies breast and ovarian cancer patients whose tumors have cancer drivers potentially responsive to treatment with human epidermal growth factor receptor 2-negative (HER2), mesenchymal-epithelial transition factor (c-MET), or phosphatidylinositol 3-kinases (PI3K) targeted therapeutics. While FDA approval or clearance is not currently required for CELsignia tests offered as a stand-alone laboratory developed test, if we are partnered with a drug company to launch a CELsignia test as a companion diagnostic for a new drug indication, we would be required to obtain premarket approval, or PMA, in conjunction with the pharmaceutical company seeking a new drug approval for the matching therapy.

We are supporting the advancement of new potential indications for three different targeted therapies, controlled by other pharmaceutical companies, that would rely on a CELsignia CDx to select patients. Three Phase 2 trials are underway to evaluate the efficacy and safety of these therapies in CELsignia selected patients. These patients are not currently eligible to receive these drugs and are not identifiable with a molecular test.

Supporting the development of a potential first-in-class targeted therapy for breast cancer, like gedatolisib, with our CELsignia platform is a natural extension of our strategy to use our CELsignia CDx to enable new indications for other companies’ targeted therapies. By combining companion diagnostics designed to enable proprietary new drug indications with targeted therapies that treat signaling dysregulation our CDx identifies, we believe we are uniquely positioned to improve the standard-of-care for many early and late-stage breast cancer patients. Our goal is to play a key role in the multiple treatment approaches required to treat breast cancer patients at various stages of their disease. With each program, we are:

• Leveraging the proprietary insights CELsignia provides into live patient tumor cell function
• Using a CELsignia CDx to identify new patients likely to respond to the paired targeted therapy
• Developing a new targeted therapeutic option for breast cancer patients
• Maximizing the probability of getting regulatory approval to market the targeted therapy indication

Recent Developments

On February 22, 2024, the Company announced that the first patient has been dosed in its Phase 1b/2 study (CELC-G-201) evaluating gedatolisib in combination with Nubeqa® (darolutamide), an approved androgen receptor inhibitor, for the treatment of patients with mCRPC.

Results of Operations

We have not generated any revenue from sales to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not and have never been profitable and have incurred losses in each period since our inception in 2012. For the three months ended March 31, 2024 and 2023, we reported a net loss of approximately $21.6 million and $11.9 million, respectively. As of March 31, 2024, we had an accumulated deficit of approximately $181.7 million. As of March 31, 2024, we had cash and cash equivalents and short-term investments of approximately $177.7 million.

Components of Operating Results

Revenue

To date, we have not generated any revenue. With the execution of the Pfizer license agreement in April 2021, whereby we acquired exclusive world-wide licensing rights to develop and commercialize gedatolisib, we initiated a Phase 3 clinical trial, VIKTORIA-1, in 2022 to support potential regulatory approval to market gedatolisib. In August 2023, we announced plans to proceed with the clinical development of gedatolisib in combination with Nubeqa® (darolutamide), an approved androgen receptor inhibitor, for the treatment of patients with mCRPC. If we obtain regulatory approvals to market gedatolisib, we expect to initially generate revenue from sales of the drug for the treatment of breast cancer patients. Additionally, we will seek to generate revenue from partnership agreements with pharmaceutical companies to provide companion diagnostics for such pharmaceutical partners’ existing or investigational targeted therapies. If a new drug indication is received that requires use of our companion diagnostic to identify eligible patients, we expect to generate revenues from sales of tests to treating physicians.

Research and Development

Since our inception, we have primarily focused on research and development of gedatolisib, a PI3K/mTOR targeted therapy and our CELsignia platform and corresponding tests. Research and development expenses primarily include:

• employee-related expenses related to our research and development activities, including salaries, benefits, recruiting, travel and stock-based compensation expenses;
• laboratory supplies;
• consulting fees paid to third parties;
• clinical trial costs;
• validation costs for gedatolisib;
• facilities expenses; and
• legal costs associated with patent applications.

Internal and external research and development costs are expensed as they are incurred. As we continue development of gedatolisib and manage studies and clinical trials, including the VIKTORIA-1 Phase 3 trial, the CELC-G-201 Phase 1b/2 trial, and other clinical trials to evaluate the efficacy of targeted therapies in cancer patients selected with one of our CELsignia tests, the proportion of research and development expenses allocated to external spending will grow at a faster rate than expenses allocated to internal expenses.

General and Administrative

General and administrative expenses consist primarily of salaries, benefits and stock-based compensation related to our executive, finance and support functions. Other general and administrative expenses include professional fees for auditing, tax, and legal services associated with being a public company, director and officer insurance, investor relations and travel expenses for our general and administrative personnel.

Sales and Marketing

Sales and marketing expenses consist primarily of professional and consulting fees related to these functions. To date, we have incurred immaterial sales and marketing expenses as we continue to focus primarily on the development of our first drug, gedatolisib, managing the VIKTORIA-1 Phase 3 and CELC-G-201 Phase 1b/2 trials, and developing our CELsignia platform and corresponding CELsignia tests. We would expect to begin to incur increased sales and marketing expenses in anticipation of the commercialization of our first drug, gedatolisib, and CELsignia tests. These increased expenses are expected to include employee-related and consulting costs.

Interest Expense

Interest expense is primarily due to a Loan Agreement and finance lease obligations.

Interest Income

Interest income consists of interest income earned on our cash, cash equivalents, and investment balances.

Results of Operations

Comparison of the Three Months Ended March 31, 2024 and 2023

Research and Development

Our research and development expenses for the three months ended March 31, 2024 were approximately $20.7 million, representing an increase of approximately $9.4 million, or 83%, compared to the same period in 2023. Of the $9.4 million increase in research and development expense, $1.5 million was related to increased employee and consulting expenses. The remaining $7.9 million increase of research and development costs are primarily related to costs supporting activities for the VIKTORIA-1 and CELC-G-201 pivotal trials.

Conducting a significant amount of research and development is central to our business model. We plan to increase our research and development expenses for the foreseeable future as we seek to develop gedatolisib, manage the VIKTORIA-1 Phase 3 and the CELC-G-201 Phase 1b/2 trials, discover new cancer sub-types, and develop and validate additional CELsignia tests to diagnose such sub-types. We also expect to incur increased expenses to support companion diagnostic business development activities with pharmaceutical companies as we develop additional CELsignia tests and manage the clinical trials for gedatolisib.

General and Administrative

Our general and administrative expenses for the three months ended March 31, 2024 were approximately $1.8 million, representing an increase of approximately $0.5 million, or 45%, compared to the same period in 2023. Of the $0.5 million increase in general and administrative expense, $0.3 million was related to increased employee and consulting expenses. The remaining $0.2 million of the $0.5 million increase resulted from professional fees and other administrative expenses.

We anticipate that our general and administrative expenses will increase in future periods, reflecting both increased costs in connection with the potential future commercialization of gedatolisib and CELsignia tests, an expanding infrastructure, and increased professional fees associated with public company regulatory developments and other compliance matters.

Interest Expense

Interest expense for the three months ended March 31, 2024 was $1.4 million and represents an increase of $0.2 million compared to the same period in 2023. Interest expense is the result of a Loan Agreement that was executed in April 2021 and amended in August 2022 and March 2024. The increase is due to the increase in prime interest rates. The $1.4 million of interest expense includes $0.5 million of non-cash interest expense.

Interest Income

Interest income for the three months ended March 31, 2024 was $2.3 million and represents an increase of $0.4 million compared to the same period in 2023. The increase was primarily the result of higher market interest rates and the closing of additional financing activities, leading to higher cash, cash equivalents and short-term investment balances.

Liquidity and Capital Resources

Since our inception, we have incurred losses and cumulative negative cash flows from operations. Through March 31, 2024, we have funded our operations primarily through private placements and registered offerings of our equity securities and unsecured convertible notes, and borrowings under loan agreements. From inception through March 31, 2024, we raised an aggregate of approximately $303.7 million of net proceeds through sales of our securities, and as of March 31, 2024 had $35.0 million of borrowings under loan agreements. In March 2024, an investor exercised 1,739,080 warrants at an exercise price of $8.05, which generated approximately $14 million in cash. The warrants were issued pursuant to a previously reported private placement that closed and was funded on December 9, 2022. Subsequent to March 31, 2024, pursuant to an Open Market Sale AgreementSM with Jefferies LLC, as agent, the Company sold 435,414 shares of common stock at an average selling price of $ 17.55 per share, generating gross proceeds of $7.6 million before deducting commissions and other offering expenses of $0.2 million. As of March 31, 2024, our cash and cash equivalents and short-term investments were approximately $31.2 million and $146.5 million, respectively, and we had an accumulated deficit of approximately $181.7 million.

Private Placement. On December 9, 2022, we issued 6,182,574 shares of common stock, 1,120,873 shares of Series A Preferred Stock and warrants exercisable for 6,956,450 shares of common stock to certain institutional and other accredited investors pursuant to a securities purchase agreement entered into on May 15, 2022. Pursuant to the securities purchase agreement, the closing (funding) of the private placement occurred following dosage of the first patient in the Company’s Phase 3 study, VIKTORIA-1. Investors purchased shares of common stock and Series A Preferred Stock at a price of $5.75 per share (on an as converted to common stock basis), with forty percent (40%) warrant coverage (on an as converted to common stock basis) and customary resale registration rights. The warrants have an exercise price of $8.05 per share. The private placement generated gross proceeds of approximately $100 million before deducting placement agent fees and other offering expenses of $4.3 million.

Pre-funded Warrants On October 18, 2023, the Company entered into a securities purchase agreement to sell pre-funded warrants at a price of $8.70 per warrant, to purchase up to 5,747,787 shares of the Company’s common stock in a private placement. The closing of the private placement occurred on October 20, 2023, and resulted in gross proceeds of approximately $50 million, before deducting offering expenses of approximately $0.1 million.

Open Market Sale AgreementSM. On February 4, 2022, we entered into an Open Market Sale AgreementSM with Jefferies LLC, as agent, pursuant to which we may offer and sell, from time to time, through Jefferies, shares of our common stock having an aggregate offering price of up to $50,000,000. On December 1, 2023, pursuant to this agreement, the Company sold 1,034,500 shares of common stock in a single transaction at a price of $14.50 per share, generating gross proceeds of $15 million ($14.4 million net of commissions and offering expenses). At March 31, 2024, $29.8 million of common stock remains available for sale under the Jefferies agreement.

Innovatus Loan Agreement. On April 8, 2021, we entered into a Loan Agreement with Innovatus Life Sciences Lending Fund I, LP (“Innovatus”), under which Innovatus agreed to loan up to $25 million in three tranches consisting of (i) a $15.0 million non-contingent Term A loan that was funded on April 8, 2021, (ii) a $5 million Term B loan with a deadline of March 31, 2022, and (iii) a $5 million Term C loan to be funded upon our request, subject to our ability to achieve certain milestones, no later than March 31, 2023. On August 9, 2022, the Company amended the Loan Agreement with Innovatus to provide for up to $75 million in term loans. As of March 31, 2024, term loans totaling $35 million are outstanding under the Loan Agreement, including the initial Term A loan of $15 million which was funded on April 8, 2021, and a $20 million Term B loan which was funded on December 22, 2022 following the closing of the $100 million private placement described above. Additionally, the Company will be able to draw on two additional tranches of $10 million and one additional tranche of $20 million upon achievement of certain clinical trial milestones and satisfaction of certain financial covenants determined on a pro forma as-funded basis. Funding of these additional tranches is also subject to other customary conditions and limits on when the Company can request funding for such tranches. On March 29, 2024, the Company entered into a Second Amendment to Loan Agreement with Innovatus in order to extend the date through which the Company may draw on the Term C loan from April 1, 2024 to June 1, 2024. Other than as set forth in the Second Amendment to Loan Agreement, the amended Loan Agreement shall continue in full force and effect without alteration or amendment.

We expect that our research and development and general and administrative expenses will increase as we continue to develop gedatolisib, manage the VIKTORIA-1 Phase 3 and CELC-G-201 Phase 1b/2 trials, conduct research related to the discovery of new cancer sub-types, conduct other studies and clinical trials, and pursue other business development activities. We would also expect to incur sales and marketing expenses as we commercialize gedatolisib and our CELsignia tests. We expect to use cash on hand, together with the funds to be received under the debt and equity financings described above, to fund our research and development expenses, clinical trial costs, capital expenditures, working capital, sales and marketing expenses, and general corporate expenses.

Based on our current business plan, we believe that our current cash, cash equivalents and short-term investments together with available borrowings under the Innovatus Loan Agreement will provide sufficient cash to finance our operations and pay obligations when due through at least 2025.

Our expectations as to how long our current capital resources will be sufficient to fund our operations are based on assumptions that may not be accurate, and we could use our current capital resources sooner than we currently expect. In addition, we may seek to raise additional capital to finance capital expenditures and operating expenses over the next several years as we launch our integrated therapeutic and companion diagnostic strategy and expand our infrastructure, commercial operations and research and development activities, and to take advantage of financing or other opportunities that we believe to be in the best interests of the Company and our stockholders. Additional capital may be raised through the sale of common or preferred equity or convertible debt securities, entry into debt facilities or other third-party funding arrangements. The sale of equity and convertible debt securities may result in dilution to our stockholders and those securities may have rights senior to those of our common shares. Agreements entered into in connection with such capital raising activities could contain covenants that would restrict our operations or require us to relinquish certain rights. Additional capital may not be available on reasonable terms, or not at all.

Cash Flows

The following table sets forth the primary sources and uses of cash for the three months ended March 31:

Operating Activities

Net cash used in operating activities was approximately $17.1 million for the three months ended March 31, 2024 and consisted primarily of a net loss of approximately $21.6 million, offset by working capital changes of $2.8 million and non-cash expense items of approximately $1.7 million. Non-cash expense items of approximately $1.7 million primarily consisted of $1.3 million of stock-based compensation expense and net non-cash interest of $0.4 million. The approximately $2.8 million of working capital changes was primarily due to increases in accrued expenses and accounts payable and a decrease in other current assets. The net cash used in operating activities was approximately $12.9 million for the three months ended March 31, 2023 and consisted primarily of a net loss of approximately $11.9 million and working capital changes of $1.0 million, offset by non-cash expense items of $0.1 million. Non-cash expense items of approximately $0.1 million primarily consisted of $1.3 million of stock-based compensation expense and non-cash interest expense of $0.5 million, offset by $1.7 million of non-cash interest income. The approximately $1.0 million of working capital changes was primarily due to a decrease in accrued expenses.

Investing Activities

Net cash provided by investing activities for the three months ended March 31, 2024 was approximately $3.5 million and consisted primarily of net proceeds from maturities of short-term investments in government securities (U.S. Treasury Bills), partially offset by $0.1 million purchases of property and equipment. Net cash provided by investing activities for the three months ended March 31, 2023 was approximately $21.9 million and consisted of net proceeds from maturities of short-term investments in government securities (U.S. Treasury Bills and U.S. government securities) and minimal purchases of property and equipment.

Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2024 was approximately $14.1 million and primarily consisted of proceeds from the exercise of common stock warrants and the exercise of employee stock options, slightly offset by payments for secondary registration costs. The net cash provided by financing activities for the three months ended March 31, 2023 was minimal and primarily consisted of the exercise of employee stock options offset by payments for secondary registration and debt issuance costs.

Recent Accounting Pronouncements

From time-to-time new accounting pronouncements are issued by the Financial Accounting Standards Board or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed in Note 2 to our unaudited condensed financial statements included in Item 1 of Part I of this Quarterly Report, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our unaudited condensed financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses during the reporting periods. These items are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances; the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ materially from these estimates.

Our significant accounting policies are more fully described in Note 2 to our unaudited condensed financial statements included in Item 1 of Part I of this Quarterly Report.

This Quarterly Report contains forward-looking statements that involve risks and uncertainties including, but not limited to, (i) our clinical trial plans and the estimated costs for such trials; (ii) our expectations with respect to our competitive advantages, including the potential efficacy of gedatolisib in various patient types alone or in combination with other treatments; (iii) our expectations regarding the timeline of patient enrollment and results from clinical trials, including our existing Phase 3 VIKTORIA-1 clinical trial and Phase 1b/2 study and clinical trial for gedatolisib; (iv) our expectations regarding our ability to obtain FDA approval to commercialize gedatolisib; (v) our expectations with respect to the development, validation, required approvals, costs and timelines of gedatolisib and our CELsignia tests; (vi) our plans with respect to research and development and related expenses for the foreseeable future; (vii) our beliefs about our ability to capitalize on the exclusive global development and commercialization rights obtained from our license agreement with Pfizer with respect to gedatolisib; (viii) the future payments that may be owed to Pfizer under the license agreement; (ix) our beliefs related to the perceived advantages of our CELsignia tests compared to traditional molecular or other diagnostic tests; (x) our revenue expectations; (xi) our expectations regarding business development activities, including collaborations with pharmaceutical companies; (xii) our expectations as to the use of proceeds from our recent financing activities; (xiii) our beliefs regarding the ability of our cash on hand to fund our research and development expenses, capital expenditures, working capital, sales and marketing expenses, and general corporate expenses, as well as the increased costs associated with being a public company; and (xiv) our plans with respect to potentially raising capital.

In some cases, you can identify forward-looking statements by the following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would,” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on our management’s beliefs and assumptions, which in turn are based on their interpretation of currently available information.

These statements involve known and unknown risks, uncertainties and other factors that may cause our results or our industry’s actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Certain risks, uncertainties and other factors include, but are not limited to, our limited operating history; our potential inability to develop, validate and commercialize gedatolisib on a timely basis or at all; the uncertainties and costs associated with clinical studies and with developing and commercializing biopharmaceuticals; the complexity and difficulty of demonstrating the safety and sufficient magnitude of benefit to support regulatory approval of gedatolisib and other products we may develop; challenges we may face in developing and maintaining relationships with pharmaceutical company partners; the complexity and timeline for development of CELsignia tests; the uncertainty and costs associated with clinical trials; the uncertainty regarding market acceptance by physicians, patients, third-party payors and others in the medical community, and with the size of market opportunities available to us; the pricing of molecular and other diagnostic products and services that compete with us; uncertainty with insurance coverage and reimbursement for our CELsignia tests; difficulties we may face in managing growth, such as hiring and retaining a qualified sales force and attracting and retaining key personnel; changes in government regulations; tightening credit markets and limitations on access to capital; and obtaining and maintaining intellectual property protection for our technology and time and expense associated with defending third-party claims of intellectual property infringement, investigations or litigation threatened or initiated against us. These and additional risks, uncertainties and other factors are described more fully in our Annual Report on Form 10-K for the year ended December 31, 2023 and elsewhere in this Quarterly Report. Copies of filings made with the SEC are available through the SEC’s electronic data gathering analysis and retrieval system (EDGAR) at www.sec.gov (http://www.sec.gov).

You should read the cautionary statements made in this Quarterly Report as being applicable to all related forward-looking statements wherever they appear in this Quarterly Report. We cannot assure you that the forward-looking statements in this Quarterly Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. You should read this Quarterly Report completely. Other than as required by law, we undertake no obligation to update these forward-looking statements, even though our situation may change in the future.

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer, referred to collectively herein as the Certifying Officers, are responsible for establishing and maintaining our disclosure controls and procedures. The Certifying Officers have reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of March 31, 2024. Based on that review and evaluation, the Certifying Officers have concluded that, as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures, as designed and implemented, are effective and provide reasonable assurance that information required to be disclosed by us in the periodic and current reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the periods specified by the SEC’s rules and forms.

Changes in Internal Control Over Financial Reporting.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As a smaller reporting company, we are not required to provide disclosure pursuant to this item. However, in addition to other information set forth in this Quarterly Report, including the important information in the section entitled “Private Securities Litigation Reform Act,” you should carefully consider the “Risk Factors” discussed in our Annual Report on Form 10-K for the year ended December 31, 2023, for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in this Quarterly Report. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial might materially adversely affect our actual business, financial condition and/or operating results.
