Overview

We are a New York City based clinical-stage biopharmaceutical company committed to advancing transformative therapies for the treatment of cancer and rare diseases. We were founded on the principle of applying modern scientific, regulatory or manufacturing advancements to established mechanisms in order to create new development opportunities. We prioritize creativity, diverse perspectives, integrity and tenacity to expedite our goal of bringing life-changing therapies to people with limited treatment options.

Our portfolio includes two development programs utilizing TARA-002, an investigational cell therapy based on the broad immunopotentiator, OK-432, which was originally granted marketing approval by the Japanese Ministry of Health and Welfare as an immunopotentiating cancer therapeutic agent. This cell therapy is currently approved in Japan and Taiwan for lymphatic malformations, or LMs, and multiple oncologic indications. We have secured worldwide rights to the asset excluding Japan and Taiwan and are exploring its use in oncology and rare disease indications. TARA-002 was developed from the same master cell bank of genetically distinct group A Streptococcus pyogenes as OK-432 (marketed as Picibanil® in Japan and Taiwan by Chugai Pharmaceutical Co., Ltd., or Chugai Pharmaceutical). We are currently developing TARA-002 in non-muscle invasive bladder cancer, or NMIBC, and in LMs.

Our lead oncology program is TARA-002 in NMIBC, which is cancer found in the tissue that lines the inner surface of the bladder that has not spread into the bladder muscle. Bladder cancer is the sixth most common cancer in the United States, with NMIBC representing approximately 80% of bladder cancer diagnoses. Approximately 65,000 patients are diagnosed with NMIBC in the United States each year. Very few new therapeutics have been approved for NMIBC since the 1990s and the current standard of care for NMIBC includes intravesical Bacillus Calmette–Guérin, or BCG. The mechanism of action of TARA-002 is similar in some ways to that of BCG. TARA-002 and BCG are both intravesically administered, elicit a Th1 type immune response and produce a generally similar array of locally activated cytokines and immune cells.

We are conducting a Phase 1 open-label clinical trial to evaluate TARA-002 in treatment-naïve and treatment-experienced NMIBC patients with carcinoma in situ, or CIS, and high-grade papillary tumors, or Ta, known as the ADVANCED-1 trial. In the initial dose escalation phase of the trial, patients received six weekly intravesical doses of TARA-002, evaluating the 10KE, 20KE and 40KE doses (Klinische Einheit, or KE, is a German term indicating a specified weight of dried cells in vial). The primary objective of the trial is to evaluate the safety, tolerability and preliminary signs of anti-tumor activity of TARA-002, with the goal of establishing a recommended Phase 2 dose. In April 2023, we announced positive preliminary data from the Phase 1a dose escalation component of the ongoing ADVANCED-1 trial through the 40KE dose, in which TARA-002 indicated favorable tolerability and anti-tumor activity in NMIBC patients. A maximum tolerated dose was not determined, and dose escalation at the 80KE dose remains ongoing in an exploratory cohort.

Preliminary data from the ADVANCED-1 trial suggested that intravesical TARA-002 was generally well tolerated at the three dose levels evaluated in the initial phase of the trial, and no dose limiting toxicities were observed. The Company has selected the 40KE dose for use in subsequent clinical trials. The majority of reported adverse events were Grades 1 and 2 across all dose levels, and treatment emergent adverse events, as assessed by study investigators, were in line with typical responses to bacterial immunopotentiation and included fatigue, headache, fever and chills. The most common urinary symptoms were urinary urgency, urinary frequency, urinary tract pain/burning, incomplete emptying, and bladder spasm. Most bladder irritations resolved soon after administration, or in a few hours to a few days. A total of nine patients were enrolled in the dose escalation portion of the study through the 40KE dose. Of those, three patients with CIS, one of whom was a heavily pre-treated BCG-unresponsive patient, achieved a complete response, or CR, at the 20KE dose, and tumor regression was observed in the other two patients. Results from six patients with high-grade, non-invasive papillary, or HGTa, tumors showed five of six patients with high-grade recurrence free survival, or HGRFS, at week 12. The patient who did not achieve HGRFS was dosed at 10KE, the lowest dose of TARA-002 offered in the trial.

The ongoing open-label expansion trial, or ADVANCED-1EXP, is evaluating intravesical TARA-002 at the 40KE dose in up to 12 CIS patients, including BCG-naïve, BCG-unresponsive, and BCG-inadequately treated patients. In April 2024, we announced positive data from three-month evaluable NMIBC patients with CIS pooled across our clinical studies, including ADVANCED-1 Phase 1a, ADVANCED-1 EXP Phase 1b and ADVANCED-2 Phase 2 trials of TARA-002 in patients with high-risk NMIBC, including BCG-Unresponsive, BCG-Experienced and BCG-Naïve patients. The overall three-month CR rate prior to reinduction for the 16 evaluable patients was 38%, with a CR rate of 63% in CIS-only patients and 13% in patients with CIS +Ta/T1 (T1 is defined as carcinoma invading the lamina propria). A 43% CR rate was observed in BCG-Unresponsive/Experienced patients. TARA-002 demonstrated a favorable safety and tolerability profile. The majority of reported adverse events were Grades 1 and 2 across all dose levels, and there were no Grade 3 or higher treatment emergent adverse events, or TEAEs. TEAEs as assessed by study investigators, were in line with typical responses to bacterial immunopotentiation, and included fatigue, headache, fever, and chills. The most common urinary symptoms were urinary urgency, urinary frequency, urinary tract pain/burning, incomplete emptying, and bladder spasm. Most bladder irritations resolved in a few hours to a few days. Additional details regarding the data, which support the potential for TARA-002 in treating high risk patients can be found in the following table:

We expect to share preliminary results from a pre-planned risk-benefit analysis of the ongoing Phase 2 open-label ADVANCED-2 trial in the second half of 2024. The analysis is expected to include approximately 10 patients who are six-month evaluable. The ongoing ADVANCED-2 trial is assessing intravesical TARA-002 in NMIBC patients with CIS (± Ta/T1) who are BCG-Naïve (n=27) and BCG-Unresponsive (n=75-100). The BCG-Unresponsive cohort has been designed to be registrational aligned with the United States Food and Drug Administration’s, or FDA’s, 2018 BCG-Unresponsive Non-muscle Invasive Bladder Cancer: Developing Drugs and Biologics for Treatment Guidance for Industry. Trial subjects will receive an induction course of six weekly intravesical instillations, and following mandatory biopsy at three months, will either receive a reinduction course of six weekly intravesical instillations of TARA-002, or the first maintenance course of three weekly installations every three months, for an additional 12 months.

In addition to the ADVANCED-2 trial, we intend to assess higher dosing at an 80KE dose and systemic priming prior to initiation of intravesical administration, in each case to assess anti-tumor activity, as well as the combination of TARA-002 with a checkpoint inhibitor in NMIBC patients with CIS.

In addition, we continue to conduct non-clinical studies on TARA-002 to better characterize the mechanism of action to help us understand how TARA-002 may perform in potential combinations with other agents used to treat NMIBC. We use non-clinical data to help us define other cancer targets for TARA-002, both within urothelial cancer and other types of cancer affecting different parts of the body.

We are also pursuing intravenous, or IV, Choline Chloride, an investigational phospholipid substrate replacement therapy, for patients receiving parenteral nutrition, or PN. Choline is a known important substrate for phospholipids that are critical for healthy liver function and also plays an important role in modulating gene expression, cell membrane signaling, brain development and neurotransmission, muscle function, and bone health. PN patients are unable to synthesize choline from enteral nutrition sources, and there are currently no available PN formulations containing choline. Approximately 80 percent of PN-dependent patients are choline-deficient and have some degree of liver damage, which can lead to hepatic failure. There are currently no available PN formulations containing choline. In the U.S. alone, there are approximately 40,000 patients on long-term PN who would benefit from an IV formulation of choline. IV Choline Chloride has the potential to become the first FDA approved IV choline formulation for PN patients.

Choline is recommended for patients on PN by the American Society for Parenteral and Enteral Nutrition, or ASPEN, in their Recommendations for Changes in Commercially Available Parenteral Multivitamin and Multi–Trace Element Products, as well as by the European Society for Clinical Nutrition and Metabolism, or ESPEN, in their Guideline on Home Parenteral Nutrition. IV Choline Chloride has been granted Orphan Drug Designation by the FDA for the prevention of choline deficiency in PN patients. We have been issued a U.S. patent by the U.S. Patent and Trademark Office claiming a choline composition with a term expiring in 2041.

In April 2024, we announced alignment with the FDA on a registrational path forward for IV Choline Chloride in patients dependent on PN. Previously, we had been pursuing an indication in intestinal failure-associated liver disease, or IFALD, and following feedback from the FDA, are pursuing a broader indication in patients on PN who are or may become unable to synthesize choline from oral or enteral nutrition sources. Feedback from the FDA on our IV Choline Chloride program indicated that a single study with an endpoint of restoring choline levels in PN patients could serve as the basis for a regulatory filing for IV Choline Chloride. We intend to advance the development of IV Choline Chloride as a source of choline for adult and adolescent patients on long-term PN.

We are also pursuing TARA-002 in LMs, which are rare, non-malignant cysts of the lymphatic vascular system that primarily form in the head and neck region of children before the age of two. In July 2020, the FDA granted Rare Pediatric Disease designation for TARA-002 for the treatment of LMs and in May 2022 the European Medicines Agency granted orphan drug designation to TARA-002 for the treatment of LMs. In addition to the clinical experience in Japan, we have secured the rights to a dataset from one of the largest ever conducted Phase 2 trials in LMs, in which OK-432 was administered via a compassionate use program led by the University of Iowa to over 500 pediatric and adult patients. We have an investigational new drug application for LMs with the Vaccines and Related Products Division of the FDA, or Vaccines Division.

In October 2023, we initiated STARBORN-1, which is a Phase 2 single-arm, open-label, prospective clinical trial to evaluate the safety and efficacy of intracystic injection of TARA-002 for the treatment of macrocystic and mixed-cystic LMs (≥ 50% macrocystic disease) in participants six months to less than 18 years of age. Including an age de-escalation safety lead-in, the trial will enroll approximately 30 patients who will receive up to four injections of TARA-002 spaced approximately six weeks apart.

The primary endpoint of the trial is the proportion of participants with macrocystic LMs and mixed-cystic LMs who demonstrated clinical success, defined as having either a complete response (90% to 100% reduction from baseline in total LM volume) or substantial response (60% to less than 90% reduction in total LM volume) as measured by axial imaging.

We have devoted substantial efforts to the development of these programs and do not have any approved products and have not generated any revenue from product sales. Neither TARA-002 nor IV Choline Chloride have been approved for use for any indications. We do not expect to generate revenues in the near-term, and it is possible we may never generate revenues in the future. To finance our current strategic plans, including the conduct of ongoing and future clinical trials and further research and development costs, we will need to raise additional capital. See “—Liquidity and Capital Resources” for additional information about our liquidity and capital resource needs.

Since inception, we have incurred significant operating losses. As of March 31, 2024, we had an accumulated deficit of approximately $211.5 million. We expect to continue to incur significant and increasing expenses and operating losses for at least the next few years as we continue our development of, and seek marketing approvals for, our product candidates, prepare for and begin the commercialization of any approved products, and add infrastructure and personnel to support our product development efforts and operations as a public company in the United States.

As a clinical-stage company, our expenses and results of operations are likely to fluctuate significantly from quarter-to-quarter and year-to-year. We believe that our period-to-period comparisons of our results of operations should not be relied upon as indicative of our future performance.

As of March 31, 2024, we had approximately $55.2 million in cash, cash equivalents, and marketable debt securities. On April 10, 2024, we completed a private placement where we sold 9,143,380 shares of common stock and, for certain purchasers, pre-funded warrants to purchase an aggregate of 1,700,000 shares of common stock. In each case, the shares and pre-funded warrants were accompanied by warrants to purchase an aggregate of up to 10,843,380 shares of common stock at a price of $5.25. We received total net proceeds of approximately $42.0 million after deducting placement agent fees and offering expenses.

Financial Overview

Research and Development

Research and development expenses consist primarily of costs incurred for the development of TARA-002 and IV Choline Chloride, which include personnel-related expenses, including salaries, benefits, travel and stock-based compensation expense, expenses incurred under agreements with clinical research organizations, or CROs, contract development and manufacturing organizations, or CDMOs, the cost of acquiring, developing and manufacturing clinical trial materials, clinical and non-clinical related costs, costs associated with regulatory operations and facilities, depreciation and other expenses, which include expenses for rent and maintenance of facilities and other supplies.

General and Administrative

General and administrative expenses consist principally of personnel-related expenses, including salaries, benefits, travel and stock-based compensation expense, in executive and other administrative functions. Other general and administrative expenses also include professional fees for legal, intellectual property matters, consulting and accounting services, facility related costs, as well as expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with our Nasdaq listing and SEC requirements, director and officer liability insurance premiums and investor relations costs associated with being a public company.

Other Income (Expense), net

Interest and investment income consists of interest and dividend income on our cash, cash equivalents and marketable debt securities and amortization of premiums and/or accretion of discounts.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial position and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and other market-specific or other relevant assumptions that we believe to be reasonable under the circumstances. Actual results may differ materially from those estimates or assumptions.

Our critical accounting policy is the accounting for accrued research and development expenses. We record accruals for estimated costs of research, preclinical, clinical and manufacturing development within accrued expenses which are significant components of research and development expenses. A substantial portion of our ongoing research and development activities are conducted by third-party service providers. We accrue costs incurred under these third-party arrangements based on estimates of actual work completed in accordance with the respective agreements. We determine the estimated costs to accrue through discussions with internal personnel and our external service providers as to the percentage of completion of the services and the agreed-upon fees to be paid for such services. Payments made to third parties under these arrangements in advance of performance of the related services are recorded as prepaid expenses until the services are rendered.

It is important that the discussion of our operating results that follow be read in conjunction with these critical accounting policies which have been disclosed in our Annual Report on Form 10-K filed with the SEC on March 13, 2024.

Results of Operations

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

The following table summarizes our results of operations for the three months ended March 31, 2024 and 2023 (in thousands):

Research and development expenses. During the three months ended March 31, 2024, our research and development expenses were approximately $7.7 million, which represented an increase of approximately $2.6 million as compared to the three months ended March 31, 2023. This increase was primarily due to an increase in expenses related to clinical trial and non-clinical activities for TARA-002 of $1.8 million as well as an increase of $1.1 million in personnel-related expenses partially offset by a reduction in clinical development activities for Choline of $0.3 million.

General and administrative expenses. During the three months ended March 31, 2024, our general and administrative expenses were approximately $4.1 million, which represented a decrease of approximately $0.5 million as compared to the three months ended March 31, 2023. This decrease was primarily due to a reduction of $0.5 million in personnel-related expenses (inclusive of $0.3 million of stock-based compensation).

Other income (expense), net. During the three months ended March 31, 2024, our other income (expense), net was approximately $0.8 million, which represented an increase of approximately $0.1 million as compared to the three months ended March 31, 2023, due primarily to higher market interest rates obtained from money market funds. 

Liquidity and Capital Resources

Overview

As of March 31, 2024 and December 31, 2023, our cash, cash equivalents, and marketable debt securities were $55.2 million and $65.6 million, respectively. We have not generated revenues since our inception and have incurred net losses of $11.1 million and $9.0 million for the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, we had working capital of $52.4 million and stockholder’s equity of $58.4 million. During the three months ended March 31, 2024, net cash flows used in operating activities were $10.4 million, consisting primarily of a net loss of $11.1 million including non-cash expenses of $1.5 million, as well as working capital adjustments of $0.7 million. Since inception, we have met our liquidity requirements principally through the sale of our common stock and preferred stock in private placements. More recently, on April 10, 2024, we completed a private placement where we sold 9,143,380 shares of common stock and, for certain purchasers, pre-funded warrants to purchase an aggregate of 1,700,000 shares of common stock. In each case, the shares and pre-funded warrants were accompanied by warrants to purchase an aggregate of up to 10,843,380 shares of common stock at a price of $5.25. We received total net proceeds of approximately $42.0 million after deducting placement agent fees and offering expenses.

We are in the business of developing biopharmaceuticals and have no current or near-term revenues. We have incurred substantial clinical and other costs in our drug development efforts. We will need to raise additional capital in order to fully realize management’s plans. 

We believe that our current financial resources, as of the date of the issuance of our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, are sufficient to satisfy our estimated liquidity needs for at least twelve months from the date of filing this quarterly report on Form 10-Q.

As a result of volatility in the capital markets, economic conditions, general global economic uncertainty, political change, global pandemics, and other factors, we do not know whether additional capital will be available when needed, or that, if available, we will be able to obtain additional capital on reasonable terms. If we are unable to raise additional capital due to the volatile global financial markets, general economic uncertainty or other factors, we may need to curtail planned development activities. Specifically, higher, and potentially increasing interest rates could impact our access to capital, and could in the future negatively affect our liquidity. A recession or market correction, continued supply chain disruptions and/or inflation could materially affect our business and the value of our common stock. Further, recent rises in interest rates have had, and may continue to have, a negative effect on market prices for common stock of public companies, especially those in the pharmaceutical industry and those that have no current or near-term revenue.

Cash Flows

The following table summarizes our sources and uses of cash for the three months ended March 31, 2024 and 2023 (in thousands):

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

Net cash used in operating activities was $10.4 million for the three months ended March 31, 2024 compared to $12.9 million for the three months ended March 31, 2023. The decrease of $2.5 million in cash used in operating activities was primarily driven by a $5.0 million decrease in working capital adjustments, primarily related to changes in prepaid expenses and other current assets, accounts payable, and accrued expenses and other current liabilities resulting from the timing of payments to our service providers offset partially by an increase in net loss of $2.1 million which includes a $0.4 million decrease in non-cash items including stock-based compensation, operating lease right-of-use asset, depreciation, and amortization of premium on marketable debt securities.

Net cash provided by investing activities was $23.1 million for the three months ended March 31, 2024 compared to $9.9 million for the three months ended March 31, 2023. The increase of $13.2 million resulted primarily from an increase in proceeds from the maturity of marketable debt securities.

Net cash used in financing activities was approximately $0.1 million for the three months ended March 31, 2024 and 2023.

Contractual and Other Obligations

Operating lease obligations

Our operating lease obligations primarily consist of lease payments on our corporate headquarters in New York, New York, as well as lease payments for our development laboratory, a manufacturing facility and an additional manufacturing space, all located in North America which are described in further detail in Note 8 of our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. 

Other obligations

From time to time, we enter into certain types of contracts that contingently require us to indemnify parties against third-party claims, supply agreements, and agreements with directors and officers. The terms of such obligations vary by contract and in most instances a maximum dollar amount is not explicitly stated therein. Generally, amounts under these contracts cannot be reasonably estimated until a specific claim is asserted, thus no liabilities have been recorded for these obligations on our condensed consolidated balance sheet for the periods presented.

We enter into contracts in the normal course of business with CROs, CDMOs, and clinical sites for the conduct of clinical trials, non-clinical research studies, professional consultants for expert advice and other vendors for clinical supply manufacturing or other services. These contracts generally provide for termination on notice, and therefore are cancelable contracts.

Certain of these agreements require us to pay milestones to such third parties upon achievement of certain development, regulatory or commercial milestones as further described in Note 9 of our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful achievement of certain development, regulatory approval and commercial milestones, which may not be achieved.

We also have obligations to make future payments to third parties that become due and payable on the achievement of certain milestones, including future payments to third parties with whom we have entered into research, development and commercialization agreements. We have not included these commitments on our condensed consolidated balance sheet for the periods presented because the achievement and timing of these milestones is not fixed and determinable.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under the applicable regulations of the SEC.

Item 3. Qualitative and Quantitative Disclosures about Market Risk

Not applicable.

Item 4. Controls and Procedures

Management’s Evaluation of our Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, or Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

As of March 31, 2024, our management, with the participation of our principal executive and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Our 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. Our principal executive and principal financial officer have concluded based upon the evaluation described above that, as of March 31, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.

We continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Changes in Internal Control Over Financial Reporting

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

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be subject to various legal proceedings and claims that arise in the ordinary course of our business activities. We are not currently a party to any legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors

In addition to the other information set forth in this Form 10-Q, including under the heading “Cautionary Note Regarding Forward-Looking Statements,” the risks and uncertainties which could adversely affect our business, financial condition, results of operations and future growth prospects that we believe are most important for you to consider are discussed in “Part II, Item 1A—Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 13, 2024. The risks described in our Annual Report on Form 10-K for the year ended December 31, 2023 are not the only risks we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. Except as set forth below, there are no material changes to the Risk Factors described in our Annual Report on Form 10-K for the year ended December 31, 2023.

We will need to raise additional financing in the future to fund our operations, which may not be available to us on favorable terms or at all.

We will require substantial additional funds to conduct the costly and time-consuming preclinical studies and clinical trials necessary to pursue regulatory approval of each potential product candidate and to continue the development of TARA-002 and IV Choline Chloride in new indications or uses. Our future capital requirements will depend upon a number of factors, including: the number and timing of future product candidates in the pipeline; progress with and results from preclinical testing and clinical trials; the ability to manufacture sufficient drug supplies to complete preclinical and clinical trials; the costs involved in preparing, filing, acquiring, prosecuting, maintaining and enforcing patent and other intellectual property claims; and the time and costs involved in obtaining regulatory approvals and favorable reimbursement or formulary acceptance. Raising additional capital may be costly or difficult to obtain and could significantly dilute stockholders’ ownership interests and divert our management’s focus on achieving our business objectives. As a result of economic conditions, general global economic uncertainty, U.S. and foreign political conditions, and other factors, we do not know whether additional capital will be available when needed, or that, if available, we will be able to obtain additional capital on reasonable terms. Further, rising inflation has, in part, caused a disruption in the capital markets and an increase in interest rates, which may lead to a recession or market correction that could impact our access to capital, increase the cost of capital, and could in the future negatively affect our liquidity. A recession or market correction, inflation and/or further increases in interest rates could materially affect our business and the value of our common stock.

In April 2024, we entered into a Subscription Agreement to sell (i) 9,143,380 shares of common stock, (ii) pre-funded warrants to purchase 1,700,000 shares of common stock (the “Pre-Funded Warrants”) and (iii) warrants to purchase an aggregate of 10,843,380 shares of common stock (the “Common Warrants”). The Pre-Funded Warrants are immediately exercisable upon issuance at an exercise price of $0.001 per share and do not expire. The Common Warrants are exercisable upon issuance at an exercise price of $5.25 per share and may be exercised at any time on or prior to the earlier of (i) April 10, 2027 and (ii) the date that is 90 days after the public announcement that the Company has demonstrated a six-month complete response rate of minimum 42% from at least 25 BCG-Unresponsive patients in the ADVANCED-2 (Cohort B) clinical trial. If we raise additional funds through public or private equity offerings, the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Further, to the extent that we raise additional capital through the sale of common stock or securities convertible or exchangeable into common stock, the ownership interests of our common stockholders will be diluted. In addition, any debt financing may subject us to fixed payment obligations and covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable intellectual property or other rights to our product candidates, technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. Even if we were to obtain sufficient funding, there can be no assurance that it will be available on terms acceptable to us or our stockholders.

The Common Warrants are speculative in nature.

The Common Warrants do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price for a limited period of time. Specifically, the Common Warrants are exercisable upon issuance at an exercise price of $5.25 per share and may be exercised at any time on or prior to the earlier of (i) April 10, 2027 and (ii) the date that is 90 days after the public announcement that the Company has demonstrated a six-month complete response rate of minimum 42% from at least 25 BCG-Unresponsive patients in the ADVANCED-2 (Cohort B) clinical trial. There can be no assurance that the market price of the common stock will ever equal or exceed the exercise price of the Common Warrants and consequently, whether it will ever be profitable for holders of the Common Warrants to exercise the warrants.

Further, if the Common Warrants are exercised in full, we would be entitled to receive the cash exercise price of $5.25 per warrant, or an aggregate of $56,927,745. We would be able to use these additional proceeds to fund our operations. To the extent the market price of our common stock does not equal or exceed the exercise price of the Common Warrants before they expire, we would not be entitled to these proceeds, and we may be required to pursue additional financing alternatives.

We will not receive a significant amount, or potentially any, additional funds upon the exercise of our Pre-Funded Warrants; however, any exercise would increase the number of shares eligible for future resale in the public market and result in substantial dilution to our stockholders.

In April 2024, we issued Pre-Funded Warrants to purchase a total of 1,700,000 shares of our common stock, all of which are outstanding as of the date of this report. Each Pre-Funded Warrant is exercisable for $0.001 per share of common stock underlying such Pre-Funded Warrant. Accordingly, we will not receive a significant amount of additional funds upon the exercise of the Pre-Funded Warrants. To the extent such Pre-Funded Warrants are exercised, additional shares of common stock will be issued for nominal consideration, which will result in dilution to the then existing holders of our common stock and will increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of the common stock, causing our stock price to decline.

The number of shares of common stock underlying our outstanding warrants is significant in relation to our currently outstanding common stock, which could have a negative effect on the market price of our common stock and make it more difficult for us to raise funds through future equity offerings. In addition, in connection with any merger, consolidation or sale of all or substantially all of our assets, holders of our outstanding warrants would be entitled to receive consideration in excess of their reported beneficial ownership of our common stock and this could adversely impact the consideration our other stockholders would receive.

In April 2024, we issued the Pre-Funded Warrants and the Common Warrants. Each Common Warrant is exercisable solely by means of a cash exercise, except that the Common Warrant is exercisable via cashless exercise if at the time of exercise, a registration statement registering the issuance of the shares of common stock underlying the common stock warrants under the Securities Act of 1933, as amended, is not then effective. The Common Warrants include certain rights upon “fundamental transactions” as described in the Common Warrants. Additionally, each holder of warrants will not be entitled to exercise any portion of any Pre-Funded Warrant or Common Warrant, which, upon giving effect to such exercise, would cause (i) the aggregate number of shares of our common stock beneficially owned by the holder (together with its affiliates) to exceed 9.99%, or for certain holders, 4.99%, of the number of shares of our common stock outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of our securities beneficially owned by the holder (together with its affiliates) to exceed 9.99% of the combined voting power of all of our securities then outstanding immediately after giving effect to the exercise. However, any holder may increase or decrease such percentage to any other percentage (not in excess of 19.99%) upon prior notice from the holder to us.

Although these warrants are subject to beneficial ownership limitations, upon exercise in full of the warrants, the shares issuable upon exercise would represent a significant portion of our outstanding common stock. As a result, the holders of these warrants may be able to exert substantial influence over our business. The concentration of voting power resulting from the exercise of the warrants could delay, defer or prevent a change of control, entrench our management and our board of directors or delay or prevent a merger, consolidation, takeover or other business combination involving us on terms that other stockholders may desire. In addition, conflicts of interest could arise in the future between us and the holders of these warrants concerning potential competitive business activities, business opportunities, the issuance of additional securities and other matters. In addition, sales of these shares could cause the market price of our common stock to decline significantly.

We will register the issuance of shares upon exercise of these warrants under a registration statement. As a result, the shares issuable upon exercise of these warrants can be freely sold in the public market upon issuance. Sales of these shares could cause the market price of our common stock to decline significantly. Furthermore, if our stock price rises, the holders of these warrants may be more likely to exercise their warrants and sell a large number of shares, which could negatively impact the market price of our common stock and reduce or eliminate any appreciation in our stock price that might otherwise occur.

Given the amount and terms of these warrants, we may find it more difficult to raise additional equity capital on favorable terms or at all while these warrants are outstanding.
