    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 failed to meet the primary endpoint of complete remission. 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, Orphan Drug and Fast Track designations 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 early in the second quarter of 2021.

    About AML

    AML is the most common form of adult leukemia, with the highest incidence in patients aged 60 years and older. AML is characterized by proliferation of abnormal immature white blood cells that impairs production of normal blood cells. AML can develop de novo or may arise secondary to progression of other hematologic disorders or from chemotherapy or radiation treatment for a different, prior malignancy; secondary AML carries a worse prognosis than de novo AML. Mutations in TP53, which are associated with poor overall prognosis, occur in approximately 20% of patients with newly diagnosed AML, more than 30% of patients with therapy-related AML and approximately 70-80% of patients with complex karyotype.

Schade, Chairman and Chief Executive Officer of Aprea. "Our dedicated team remains committed to the clinical development of eprenetapopt and our next generation, oral p53 reactivator, APR-548, in hematological and solid tumor malignancies. In 2021, we look forward to sharing data from our current clinical studies as well as our plans to expand the clinical pipeline to include new indications."

    Business Operations Update: 

    The Company is conducting, supporting, and planning multiple clinical trials of eprenetapopt (APR-246) and APR-548:

    • Pivotal Phase 3 MDS Trial—In December 2020, the Company announced its pivotal Phase 3 randomized, controlled trial evaluating eprenetapopt with azacitidine as frontline therapy in HMA-naïve TP53 mutant myelodysplastic syndromes (MDS) patients failed to meet its predefined primary endpoint of complete remission (CR) rate. Analysis of the primary endpoint at this data cut demonstrated a 53% higher number of patients achieving a CR in the experimental arm receiving eprenetapopt with azacitidine versus the control arm receiving azacitidine alone but did not reach statistical significance. The Company is completing analysis from this Phase 3 clinical trial and expects to present additional information in the second quarter of 2021.
    • Phase 2 MDS/AML Post-Transplant Trial – The Company has completed enrollment of 33 patients in a single-arm, open-label Phase 2 clinical trial evaluating eprenetapopt with azacitidine as post-transplant maintenance therapy in TP53 mutant MDS and AML patients who have received an allogeneic stem cell transplant. The Company anticipates initial results from the primary endpoint of relapse-free survival at 12 months in the second quarter of 2021.
    • Phase 1/2 AML Trial – The Company is currently enrolling a Phase 1/2 clinical 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 33 additional frontline TP53 mutant AML patients with the combination of eprenetapopt, venetoclax and azacitidine. In the 19 frontline AML patients who are evaluable for efficacy with the triplet regimen, the Company has observed a 63% CR + CRi composite response rate and a 31% CR rate. The Company anticipates completion of enrollment in the triplet regimen expansion cohort during the second quarter of 2021 with availability of preliminary response rate data from the cohort also in the second quarter of 2021.
    • Phase 1 NHL Trial – The Company is currently enrolling 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. The first patient was enrolled in the first quarter of 2021. The Company is also planning to evaluate the combination of eprenetapopt with venetoclax in relapsed/refractory mantle cell lymphoma.
    • Phase 1/2 Solid Tumor Trial – The Company is currently enrolling a Phase 1/2 clinical trial in relapsed/refractory gastric, bladder and non-small cell lung cancers assessing eprenetapopt with anti-PD-1 therapy. The dose-escalation phase of the trial enrolled 6 patients with advanced solid tumors and no dose-limiting toxicities were observed. Based on these results, the Company is enrolling expansion cohorts for patients with advanced gastric, bladder and non-small cell lung cancers and has currently enrolled 8 patients across these expansion arms.
    • APR-548 -- The Company's second product candidate, APR-548, is a next-generation p53 reactivator that is being developed in an oral dosage form. The Company has planned a Phase 1 dose-escalation clinical trial evaluating the safety, tolerability, and preliminary efficacy of APR-548 with azacitidine in frontline and relapsed/refractory MDS patients. The Company anticipates the first patient to be enrolled early in the second quarter of 2021.

    Fourth Quarter Financial Results

    • Cash and cash equivalents:  As of December 31, 2020, the Company had $89.0 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 2021 to be between $30.0 million $35.0 million. The Company believes its cash and cash equivalents as of December 31, 2020 will be sufficient to meet its current projected operating requirements into 2023.  

    • Research and Development (R&D) expenses:  R&D expenses were $9.3 million for the quarter ended December 31, 2020, compared to $8.0 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; its pivotal Phase 3 clinical trial of eprenetapopt with azacitidine for frontline treatment of TP53 mutant MDS, its Phase 1/2 clinical trial for the treatment of TP53 mutant AML with venetoclax and azacitidine, its Phase 1/2 clinical trial in relapsed/refractory gastric, bladder and non-small cell lung cancers assessing eprenetapopt with anti-PD-1 therapy, its Phase 1 clinical trial in relapsed/refractory TP53 mutant chronic lymphoid leukemia (CLL) assessing eprenetapopt with venetoclax and rituximab, and eprenetapopt with ibrutinib and its Phase 2 post-transplant MDS/AML clinical trial.

    • General and Administrative (G&A) expenses:  G&A expenses were $4.9 million for the quarter ended December 31, 2020, compared to $3.9 million for the comparable period in 2019. The increase in G&A expenses was primarily due to increases in non-cash stock-based compensation, insurance expense and commercial development expense.

    • Net loss:  Net loss was $15.4 million, or $0.73 per share for the quarter ended December 31, 2020, compared to a net loss of $13.1 million, or $0.64 per share for the quarter ended December 31, 2019.   The Company had 21,186,827 shares of common stock outstanding as of December 31, 2020.

    • The trial failed to meet its primary endpoint of complete remission (CR) rate
    • CR rate was 53% higher in eprenetapopt with AZA arm compared to AZA alone, but did not reach statistical significance

    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).

    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.
