Business Overview and Chronology
Aprea Therapeutics, Inc. (NASDAQ:APRE) is a clinical-stage biopharmaceutical company at the forefront of precision oncology, leveraging the power of synthetic lethality to develop groundbreaking cancer therapies. With a focus on DNA damage response (DDR) pathways, Aprea has assembled a promising pipeline of novel product candidates poised to transform the treatment landscape for patients battling a wide range of malignancies.
Aprea Therapeutics was originally incorporated in 2002 and commenced principal operations in 2006. Initially, the company focused on developing cancer therapeutics that reactivate the mutant p53 tumor suppressor protein. However, a significant shift occurred in December 2020 when Aprea announced that its pivotal Phase 3 myelodysplastic syndromes trial failed to meet its predefined primary endpoint of complete remission rate. This setback, combined with FDA feedback and the high costs associated with continuing the APR-246 development program, led to a strategic pivot.
In May 2022, Aprea acquired Atrin Pharmaceuticals Inc., marking a transformative moment for the company. This acquisition brought new assets and redirected Aprea’s focus towards the discovery and development of molecules targeting DNA damage response (DDR) pathways in oncology through synthetic lethality. This strategic move has since defined the company’s core business.
The company’s two lead clinical programs, which form the cornerstone of its synthetic lethality-based cancer therapeutics pipeline, are ATRN-119, a novel oral macrocyclic ATR inhibitor, and APR-1051, a next-generation oral inhibitor of the WEE1 kinase. Both of these programs were internally discovered, developed, and evaluated by Aprea’s dedicated team of chemists, scientists, and clinicians, showcasing the company’s in-house expertise and capabilities.
It’s worth noting that Aprea no longer has any significant ongoing preclinical studies or clinical trials involving APR-246, its previous reactivator of mutant p53 program. The company has primarily financed its operations through the net proceeds received from the initial public offering of its common stock and subsequent sales of common stock through public and private offerings since 2019.
Financial Snapshot
As of September 30, 2024, Aprea reported $26.2 million in cash and cash equivalents, providing a cash runway for at least twelve months. This cash position reflects the company’s successful $16 million private placement financing in March 2024, which included the issuance of common stock, pre-funded warrants, and tranche A and B warrants.
For the nine months ended September 30, 2024, Aprea reported revenue of $1.30 million, primarily derived from grant funding. However, the company has not yet generated any commercial revenue, as its lead product candidates remain in clinical development. During this period, Aprea incurred a net loss of $10.06 million, with research and development expenses of $7.00 million and general and administrative expenses of $5.39 million.
The company’s financial performance has been marked by consistent losses, as is typical for a clinical-stage biopharmaceutical firm. Aprea’s accumulated deficit stood at $318.15 million as of September 30, 2024, reflecting the significant investments required to advance its pipeline.
For the most recent fiscal year (2023), Aprea reported a net loss of $14,286,756. In the most recent quarter (Q3 2024), the company reported no revenue and a net loss of $3,783,769. The operating cash flow for Q3 2024 was -$2,468,302, which was also equal to its free cash flow for the period.
Liquidity
Aprea’s liquidity position is critical for its ongoing operations and clinical development activities. The $26.2 million in cash and cash equivalents reported as of September 30, 2024, provides the company with a runway of at least twelve months. This liquidity was bolstered by the $16 million private placement financing in March 2024, which included the issuance of various securities.
The company’s ability to maintain adequate liquidity is crucial for advancing its pipeline and supporting ongoing research and development efforts. As Aprea continues to progress its clinical programs, it may need to seek additional financing through various means, such as public or private equity offerings, debt financing, or strategic collaborations.
Aprea’s financial position is characterized by a debt-to-equity ratio of 0, as the company has no debt. The current ratio and quick ratio both stand at 7.28, indicating a strong short-term liquidity position. These ratios suggest that Aprea has sufficient current assets to cover its short-term liabilities.
Pipeline and Clinical Progress
ATRN-119: Aprea’s lead product candidate, ATRN-119, is a clinical-stage oral small molecule inhibitor of the ATR kinase, a master regulator of the DNA damage response. The company is currently enrolling patients into the ABOYA-119 Phase 1/2a clinical trial to evaluate ATRN-119 under an investigational new drug (IND) application. The primary endpoint of the Phase 1 portion is to assess the tolerability and pharmacokinetics of ATRN-119 when administered orally on a continuous, once-daily schedule.
Preliminary data from the ongoing ABOYA-119 trial have demonstrated ATRN-119’s ability to be safe and well-tolerated, with no dose-limiting toxicities and no signs of significant hematological toxicity reported. Based on these interim results, Aprea has amended the study protocol to add additional patient cohorts, including a higher dose level and an evaluation of the effect of food on ATRN-119 absorption and drug exposure. The company anticipates potential efficacy data readout from this trial in the second half of 2025. Additionally, Aprea is evaluating a twice-daily dosing regimen and a higher once-daily dose level under the new protocol.
APR-1051: Aprea’s second clinical program is APR-1051, an orally bioavailable, highly potent, and selective small molecule inhibitor of the WEE1 kinase. In March 2024, the FDA cleared Aprea’s IND application for APR-1051, and the company subsequently enrolled the first patient into the ACESOT-1051 Phase 1 dose-escalation study.
Preliminary results from the ACESOT-1051 trial indicate that APR-1051 is safe and well-tolerated, with no hematologic toxicity and only one possible treatment-related Grade 1 adverse event observed at the dose levels assessed thus far. Active enrollment is ongoing at three sites in the U.S., and Aprea expects to report open-label safety and efficacy data from this trial in the first half of 2025. As of November 4, 2024, Aprea is enrolling the fourth cohort of the study to evaluate a subtherapeutic 50 mg once-daily dose.
In addition to the development of these drug candidates as single agents, Aprea is also evaluating potential combination opportunities, including a preclinical research program on the combination of ATRN-119 and APR-1051 supported by a Phase II SBIR grant from the National Cancer Institute. The company also has an early preclinical research program targeting an undisclosed DNA damage response (DDR) pathway.
