    • The trial failed to meet its primary endpoint of complete remission (CR) rate

    BOSTON, Dec. 28, 2020 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (NASDAQ:APRE), a biopharmaceutical company focused on developing and commercializing novel cancer therapeutics that reactivate the mutant tumor suppressor protein, p53, today announced results of the primary data cut from its Phase 3 clinical trial evaluating the safety and efficacy of eprenetapopt with azacitidine (AZA) versus AZA alone in TP53 mutant myelodysplastic syndromes (MDS). The trial did not meet the predefined primary endpoint of complete remission (CR) rate.   Analysis of the primary endpoint at this data cut demonstrated a higher CR rate in the experimental arm receiving eprenetapopt with AZA versus the control arm receiving AZA alone, but did not reach statistical significance. In the intention-to-treat population of 154 patients, the CR rate in the eprenetapopt with AZA arm was 33.3% (95% CI: 23.1% - 44.9%) compared to 22.4% (95% CI: 13.6% - 33.4%) in the AZA alone arm (P = 0.13).

    While analysis of certain secondary endpoints (ORR and duration of responses) appears to favor the experimental arm at this data cut, they are not significantly different. The median duration of overall survival at the primary data cut was similar between the arms. Additional patients in the study who have not achieved a CR remain on study treatment and the data will be analyzed at future pre-specified timepoints as set forth in the statistical analysis plan. The combination of eprenetapopt with AZA appeared well-tolerated, with an adverse event profile that was similar to the Company's prior Phase 2 clinical trials. Subsequent analyses of the trial data, including secondary endpoints, will be conducted as the duration of patient follow-up increases. The Company expects to present the data at a future scientific conference.

    "Though we are disappointed the topline results did not reach statistical significance, we continue to believe that eprenetapopt can offer clinical benefit to patients with TP53 mutant malignancies," said Dr. Eyal Attar, Chief Medical Officer of Aprea. "We will continue to analyze data as it matures and follow patients who are still receiving study treatment. Our other clinical trials continue to progress and we remain committed to pursuing our clinical development programs."

    About the Phase 3 Trial in TP53 Mutant MDS

    The Phase 3 trial enrolled 154 TP53 mutant MDS patients, randomized 1:1 to either the eprenetapopt with AZA arm or the AZA alone arm. Response criteria are those defined by International Working Group 2006 (IWG 2006) and include measures of peripheral blood counts and bone marrow blasts.

    About p53, eprenetapopt and APR-548

    The p53 tumor suppressor gene is the most frequently mutated gene in human cancer, occurring in approximately 50% of all human tumors. These mutations are often associated with resistance to anti-cancer drugs and poor overall survival, representing a major unmet medical need in the treatment of cancer.

    Eprenetapopt (APR-246) is a small molecule that has demonstrated reactivation of mutant and inactivated p53 protein – by restoring wild-type p53 conformation and function – thereby inducing programmed cell death in human cancer cells. Pre-clinical anti-tumor activity has been observed with eprenetapopt in a wide variety of solid and hematological cancers, including MDS, AML, and ovarian cancer, among others. Additionally, strong synergy has been seen with both traditional anti-cancer agents, such as chemotherapy, as well as newer mechanism-based anti-cancer drugs and immuno-oncology checkpoint inhibitors. In addition to pre-clinical testing, a Phase 1/2 clinical program with eprenetapopt has been completed, demonstrating a favorable safety profile and both biological and confirmed clinical responses in hematological malignancies and solid tumors with mutations in the TP53 gene.

    A pivotal Phase 3 clinical trial of eprenetapopt and azacitidine for frontline treatment of TP53 mutant MDS has been completed and additional clinical trials in hematologic malignancies and solid tumors are ongoing. Eprenetapopt has received Breakthrough Therapy, Orphan Drug and Fast Track designations from the FDA for MDS, Fast Track designation from the FDA for AML, and Orphan Drug designation from the European Medicines Agency for MDS, AML and ovarian cancer.

    APR-548 is a next-generation small molecule p53 reactivator. APR-548 has demonstrated high oral bioavailability, enhanced potency relative to eprenetapopt in TP53 mutant cancer cell lines and has demonstrated in vivo tumor growth inhibition following oral dosing of tumor-bearing mice. Enrollment in a Phase 1 clinical trial of APR-548 is anticipated to begin in the first quarter of 2021.

    BOSTON, Nov. 05, 2020 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (NASDAQ:APRE), a biopharmaceutical company focused on developing and commercializing novel cancer therapeutics that reactivate the mutant tumor suppressor protein, p53, today reported financial results for the three and nine months ended September 30, 2020 and provided a business update.

    "We made solid progress during the third quarter across our development pipeline as we approach top-line data from the Phase 3 clinical trial evaluating eprenetapopt with azacitidine for the treatment of front-line TP53 mutant myelodysplastic syndromes (MDS) patients by year-end 2020" said Christian S. Schade, Chairman and Chief Executive Officer of Aprea.  "We continue to execute on our goal of expanding the clinical opportunities for our p53 reactivator programs, including expansion of our front-line AML clinical trials, enrollment of the first patients in our solid tumor trial, initiation of our lymphoma trial and clearance from FDA to proceed with the Phase 1 trial of our next-generation p53 reactivator, APR-548."

    Business Operations Update: 

    The Company is conducting, supporting, and planning multiple clinical trials of eprenetapopt (APR-246):

    • Pivotal Phase 3 MDS Trial—The Company has completed the full enrollment of 154 patients in its pivotal Phase 3 randomized, controlled trial evaluating eprenetapopt with azacitidine as frontline therapy in HMA-naïve TP53 mutant myelodysplastic syndromes (MDS) patients with a primary endpoint of complete remission (CR) rate. The Company remains confident it will have top-line data available by year-end 2020.



    • Phase 2 MDS/AML Post-Transplant Trial—The Company has completed the target enrollment of 31 patients in its single-arm, open-label Phase 2 trial evaluating eprenetapopt with azacitidine as post-transplant maintenance therapy in TP53 mutant MDS and acute myeloid leukemia (AML) patients who have received an allogeneic stem cell transplant.



    • Phase 1/2 AML Trial—The Company is currently enrolling its Phase 1/2 trial evaluating the safety, tolerability, and preliminary efficacy of eprenetapopt therapy in TP53 mutant AML patients. The lead-in portion of the trial evaluated the tolerability of eprenetapopt with venetoclax, with or without azacitidine, and no dose-limiting toxicities were observed in 12 patients receiving either regimen. Based on these results, the Company has expanded the trial to treat approximately 30 additional frontline TP53 mutant AML patients with the combination of eprenetapopt, venetoclax and azacitidine. The Company also plans to activate a separate cohort in the trial to evaluate the combination of eprenetapopt with azacitidine in approximately 30 frontline TP53 mutant AML patients.



    • Phase 1 NHL Trial—The Company has designed and plans to conduct a Phase 1 clinical trial in relapsed/refractory TP53 mutant chronic lymphoid leukemia (CLL) assessing eprenetapopt with venetoclax and rituximab, and eprenetapopt with ibrutinib in order to further assess eprenetapopt in hematological malignancies. A poster describing the clinical trial has been accepted for presentation at the 62nd American Society of Hematology (ASH) Annual Meeting (abstract # 1311) on December 5, 2020 from 10:00 am to 6:30 pm eastern time. The Company is targeting the first patient to be enrolled in the fourth quarter of 2020.



    • Phase 1/2 Solid Tumor Trial—Based on in vivo data suggesting synergistic activity between eprenetapopt and immuno-therapy agents including anti-PD-1 antibody, the Company has designed and is conducting Phase 1/2 clinical trials in relapsed/refractory gastric, bladder and non-small cell lung cancers assessing eprenetapopt with anti-PD-1 therapy. Five patients have been enrolled in the safety review cohort of this trial.



    • APR-548 -- The Company's second product candidate, APR-548, is a pre-clinical, next-generation p53 reactivator with the potential for oral administration. APR-548 exhibits high oral bioavailability in preclinical testing and is being developed in an oral dosage form. The Company completed Investigational New Drug, or IND, enabling preclinical studies of APR-548 and filed an IND with the FDA. The Company received clearance from the FDA in October 2020 to initiate Phase 1 clinical trials for APR-548. The Company anticipates enrollment in the Phase 1 clinical trial to begin in the first quarter of 2021.

    Third Quarter Financial Results

    • Cash and cash equivalents:  As of September 30, 2020, the Company had $101.1 million of cash and cash equivalents compared to $130.1 million of cash and cash equivalents as of December 31, 2019. The Company expects cash burn for the full year 2020 to be between $35.0 million $40.0 million.  The Company believes its cash and cash equivalents as of September 30, 2020 will be sufficient to meet its current projected operating requirements into 2023.  



    • Research and Development (R&D) expenses:  R&D expenses were $8.8 million for the quarter ended September 30, 2020, compared to $4.9 million for the comparable period in 2019. The increase in R&D expenses was primarily related to the continued development of the Company's lead product candidate, eprenetapopt in the following ongoing clinical trials; our pivotal Phase 3 clinical trial of eprenetapopt with azacitidine for frontline treatment of TP53 mutant MDS, our Phase 1/2 clinical trials in relapsed/refractory gastric, bladder and non-small cell lung cancers assessing eprenetapopt with anti-PD-1 therapy, our Phase 1 clinical trial in relapsed/refractory TP53 mutant chronic lymphoid leukemia (CLL) assessing eprenetapopt with venetoclax and rituximab, and eprenetapopt with ibrutinib and our Phase 2 post-transplant MDS/AML clinical trial.

       
    • General and Administrative (G&A) expenses:  G&A expenses were $3.5 million for the quarter ended September 30, 2020, compared to $2.3 million for the comparable period in 2019.  The increase in G&A expenses was primarily due to increased non-cash stock-based compensation, increased insurance expense and increased commercial development expense.

       
    • Net loss:  Net loss was $12.3 million, or $0.58 per share for the quarter ended September 30, 2020, compared to a net loss of $6.2 million, or $5.29 per share for the quarter ended September 30, 2019. The Company had 21,186,827 shares of common stock outstanding as of September 30, 2020.

    About p53, eprenetapopt and APR-548

    The p53 tumor suppressor gene is the most frequently mutated gene in human cancer, occurring in approximately 50% of all human tumors.  These mutations are often associated with resistance to anti-cancer drugs and poor overall survival, representing a major unmet medical need in the treatment of cancer.

    Eprenetapopt (APR-246) is a small molecule that has demonstrated reactivation of mutant and inactivated p53 protein – by restoring wild-type p53 conformation and function – thereby inducing programmed cell death in human cancer cells.  Pre-clinical anti-tumor activity has been observed with eprenetapopt in a wide variety of solid and hematological cancers, including MDS, AML, and ovarian cancer, among others.  Additionally, strong synergy has been seen with both traditional anti-cancer agents, such as chemotherapy, as well as newer mechanism-based anti-cancer drugs and immuno-oncology checkpoint inhibitors. In addition to pre-clinical testing, a Phase 1/2 clinical program with eprenetapopt has been completed, demonstrating a favorable safety profile and both biological and confirmed clinical responses in hematological malignancies and solid tumors with mutations in the TP53 gene.

    A pivotal Phase 3 clinical trial of eprenetapopt and azacitidine for frontline treatment of TP53 mutant MDS is ongoing. Eprenetapopt has received Breakthrough Therapy, Orphan Drug and Fast Track designations from the FDA for MDS, and Orphan Drug designation from the European Medicines Agency for MDS, AML and ovarian cancer.

    APR-548 is a next-generation small molecule p53 reactivator. APR-548 has demonstrated high oral bioavailability, enhanced potency relative to eprenetapopt in TP53 mutant cancer cell lines and has demonstrated in vivo tumor growth inhibition following oral dosing of tumor-bearing mice. A Phase 1 clinical trial of APR-548 in TP53 MDS is planned.
