Aprea Therapeutics Reports Second Quarter 2022 Financial Results and Provides Update on Business Operations

August 11, 2022

BOSTON, Aug. 11, 2022 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (Nasdaq: APRE), a biopharmaceutical company focused on developing and commercializing novel synthetic lethality-based cancer therapeutics targeting DNA damage response (DDR) pathways today reported financial results for the three and six months ended June 30, 2022 and provided a business update.

“This is an exciting time for Aprea as we advance our ATR program into clinical development this year, continue to progress our WEE1 program toward IND submission and leverage our unique discovery platform capabilities to build for future success,” said Oren Gilad, Ph.D., President and Chief Executive Officer of Aprea. “We believe our current cash resources will last through the end of 2023 and enable us to execute on our development plan to reach near term clinical milestones.”

Second Quarter Financial Results

  • Cash and cash equivalents: As of June 30, 2022, the Company had $39.1 million of cash and cash equivalents compared to $53.1 million of cash and cash equivalents as of December 31, 2021. The Company believes its cash and cash equivalents as of June 30, 2022 will be sufficient to meet its current projected operating requirements through the end of 2023.
  • Research and Development (R&D) expenses: R&D expenses were $6.8 million for the quarter ended June 30, 2022, compared to $6.7 million for the comparable period in 2021. R&D expenses for the quarter ended June 30, 2022 primarily represented close out costs for (i) the Company’s pivotal Phase 3 clinical trial of eprenetapopt with azacitidine for the frontline treatment of TP53 mutant MDS, (ii) the Company’s Phase 2 post-transplant MDS/AML clinical trial, (iii) the Company’s Phase 1 AML trial, and (iv) the Company’s Phase 1/2 solid tumor trial and the Company’s Phase 1 dose-escalation trial of APR-548.
  • General and Administrative (G&A) expenses: G&A expenses were $15.6 million for the quarter ended June 30, 2022, compared to $3.3 million for the comparable period in 2021.  The increase in G&A expenses was primarily due to an increase in non-cash stock-based compensation expense resulting from the acceleration of vesting of all outstanding stock options and restricted stock units in connection with the acquisition of Atrin in May 2022.
  • Acquired In-Process Research and Development (IPR&D) expenses: Acquired IPR&D expense was $76.0 million for the quarter ended June 30, 2022. Acquired IPR&D resulted from the Atrin Acquisition in May 2022 which was accounted for as an asset acquisition. The acquisition cost allocated to acquired IPR&D with no alternative future use was recorded as an expense as of the closing date.
  • Net loss: Net loss was $98.3 million, or $4.34 per share for the quarter ended June 30, 2022, compared to a net loss of $10.3 million, or $0.48 per share for the quarter ended June 30, 2021. The increase in net loss was primarily attributable to the acquired in process research and development of $76.0 million associated with the Atrin acquisition. The Company had 23,401,846 shares of common stock outstanding as of June 30, 2022.

Business Operations Update: 

On May 16, 2022 the Company completed the acquisition of Atrin Pharmaceuticals, Inc. (“Atrin”), a privately held biotechnology company focused on the discovery and development of novel therapeutics targeting proteins in the DDR, pathway in oncology through synthetic lethality. Following the Company’s Annual Meeting of Stockholders on July 28, 2022, Christian S. Schade transitioned to the role of Executive Chairman of the Board of Directors and Oren Gilad, Ph.D., assumed the role of Chief Executive Officer.

DDR Programs

ATRN-119 – ATRN-119 is an orally-bioavailable, highly potent and selective macrocyclic small molecule inhibitor of ATR, a protein with key roles in response to DNA damage. ATRN-119 has received FDA IND approval for a first-in-human clinical trial for cancer patients and this trial is expected to begin in the third quarter of 2022.

ATRN-W1051 – ATRN-W1051 is an orally-bioavailable, highly potent and selective small molecule inhibitor of WEE1, a key regulator of multiple phases of the cell cycle. ATRN-W1051 is currently in preclinical development and we anticipate commencing IND-enabling studies in the second half of 2022.

p53 Reactivator Programs

Eprenetapopt - APR-246, or eprenetapopt, is a small molecule p53 reactivator that has been tested in clinical trials for solid tumors and for hematologic malignancies. A manuscript describing the results of a Phase 2 clinical trial of eprenetapopt with azacitidine after allogeneic stem-cell transplantation in TP53 mutant acute myeloid leukemia and myelodyspastic syndromes has recently been published online in the Journal of Clinical Oncology and a manuscript describing results of a Phase 1b clinical trial of eprenetapopt with pembrolizumab in advanced solid tumors has been accepted for publication in ESMO Open. We currently have no ongoing clinical trials of eprenetapopt.

APR-548 - APR-548 is a second generation p53 reactivator that is a unique analog of eprenetapopt. APR-548 exhibits high oral bioavailability in preclinical testing and is being developed in an oral dosage form. We initiated a Phase 1 clinical trial testing APR-548 in relapsed/refractory MDS and AML. Enrollment in the first dosing cohort was completed. There are currently no patients receiving APR-548 in this trial and enrollment into the trial has been closed.
