DOYLESTOWN, Pa., March 30, 2023 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (Nasdaq: APRE) (“Aprea”, or the “Company”), a clinical stage biopharmaceutical company focused on developing novel synthetic lethality-based cancer therapeutics targeting DNA damage response (DDR) pathways, today reported financial results for the three months and year ended December 31, 2022 and provided a business update.

“2022 has been another transformational year for Aprea with progress on multiple fronts,” said Oren Gilad, Ph.D., President and Chief Executive Officer of Aprea. “With the initiation of the Phase 1/2a clinical trial of our ATR inhibitor, ATRN-119, we remain on track to provide an update on clinical data later this year. Following this important achievement, we further strengthened our cash position with the closing of a public offering pursuant to which we received approximately $5.5 million in gross proceeds, allowing us to extend our cash runway into the third quarter of 2024. We believe our current cash runway will allow us to cross meaningful clinical milestones for our two lead programs. Additionally, we announced a non-dilutive SBIR award from the National Cancer Institute and welcomed John Hamill to the Aprea team. We look forward to his contribution as Chief Financial Officer as we advance our clinical pipeline of synthetic lethality-based cancer therapeutics targeting DDR pathways.”

Key Business and Financial Updates

• ATR inhibitor program: ATRN-119 – Significant progress made on the development of our lead ATR inhibitor program. Our lead clinical candidate, ATRN-119, is a potential best-in-class oral ATR inhibitor for treatment of advanced solid tumors harboring defined mutations in DDR pathways. The Phase 1/2a trial continues to enroll patients with biomarkers related to DDR mutations. ATRN-119 is an orally bioavailable, potent and selective macrocyclic small molecule inhibitor of ATR, a protein with key roles in response to DNA damage. The primary endpoint of the Phase 1 dose escalation part of the study is to assess safety/tolerability, pharmacokinetics and recommended Phase 2 dose. The Phase 2a expansion part of the study is designed to further evaluate tolerability and preliminary efficacy of ATRN-119 monotherapy in advanced solid tumors.
• WEE1 inhibitor program: ATRN-1051 – ATRN-1051 is an orally-bioavailable, highly potent and selective small molecule inhibitor of WEE1, a key regulator of multiple phases of the cell cycle. The Company believes that preclinical findings show potentially favorable drug selectivity and exposure. IND-enabling studies with ATRN-1051 are under way and the Company anticipates filing of an IND with the FDA by the end of 2023.
• An abstract on combination of ATRN-119 and ATRN-1051 was selected for presentation as a poster at the American Association for Cancer Research (AACR) 2023 Annual Meeting, being held April 14-19, 2023, in Orlando, Florida.
• Obtained non-dilutive funding via a research grant from the National Cancer Institute (NCI) supporting development of DDR inhibitors. The Company announced that it received an award notification from the NCI for the development of a first-in-class combination of DNA damage response inhibitors for the treatment of high-grade serous ovarian cancer (HGSOC). HGSOC is a devastating disease responsible for the deaths of about 125,000 women worldwide each year and has low survival rates.
• Announced the Company had regained compliance with Nasdaq’s minimum bid price requirement for continued listing on the Nasdaq Global Select Market.
• Closed an underwritten public offering in Q1 of 2023 pursuant to which we received approximately $5.5 million in gross proceeds. The net proceeds received from the public offering will enable the Company to continue developing its clinical asset, ATRN-119, its pre-clinical asset ATRN-1051 and for general corporate purposes.

Select Financial Results for the Fourth Quarter ended December 31, 2022

• As of December 31, 2022, the Company reported cash and cash equivalents of $28.8 million.
• For the fourth quarter ended December 31, 2022, the Company reported an operating loss of $2.7 million, compared to an operating loss of $7.8 million in the fourth quarter of 2021.
• Research and Development (R&D) expenses were $0.5 million for the quarter ended December 31, 2022, compared to $4.5 million for the fourth quarter of 2021. The decrease in R&D expense was primarily related to the wrap up and close out of legacy Aprea clinical trials which were largely completed by the fourth quarter 2022. Aprea only had one active clinical trial in the 4^th quarter of 2022 compared to six active clinical trials in the 4^th quarter of 2021.
• General and Administrative (G&A) expenses were $2.1 million for the quarter ended December 31, 2022, compared to $3.4 million for the comparable period in 2021.  The decrease in G&A expenses was primarily due to a decrease in non-cash stock-based compensation.
• The Company reported a net loss of $2.4 million ($0.92 per basic share) on approximately 2.6 million weighted-average common shares outstanding for the quarter ended December 31, 2022, compared to a net loss of $7.8 million ($7.20 per basic share) on approximately 1.1 million weighted average common shares outstanding for the comparable period in 2021.

Select Financial Results for the Year ended December 31, 2022

• As of December 31, 2022, the Company reported cash and cash equivalents of $28.8 million compared to $53.1 million as of December 31, 2021. The Company believes its cash and cash equivalents as of December 31, 2022, combined with the gross proceeds received from the Company’s $5.5 million public offering of common stock in February 2023 will be sufficient to meet its current projected operating requirements into the third quarter of 2024.
• For the year ended December 31, 2022, the Company reported an operating loss of $113.4 million, which include $76.0 million for acquired in-process research and development, compared to an operating loss of $37.4 million for the year ended December 31, 2021.
• Research and Development (R&D) expenses were $16.4 million for the year ended December 31, 2022, compared to $23.9 million for the year ended December 31, 2021. The decrease in R&D expense was primarily related to the wrap up and close out of legacy Aprea clinical trials which were largely completed by the fourth quarter of 2022.
• General and Administrative (G&A) expenses were $21.0 million for the year ended December 31, 2022, compared to $13.6 million for the year ended December 31, 2021. The increase in G&A expenses was primarily due to an increase in non-cash stock-based compensation from the acceleration of vesting of all outstanding stock options and restricted stock units in connection with the acquisition of Atrin Pharmaceuticals Inc. in May 2022.
• The Company reported a net loss was of $112.7 million ($67.99 per basic share) on approximately 1.7 million weighted-average common shares outstanding for the year ended December 31, 2022, compared to a net loss of $37.1 million ($34.88 per basic share) on approximately 1.1 million weighted average common shares outstanding for the same period in 2021.
