DOYLESTOWN, Pa., May 13, 2026 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (Nasdaq: APRE) (“Aprea”, or the “Company”), a clinical-stage precision medicine oncology company focused on the discovery and development of targeted therapies for patients with biomarker-defined cancers, today reported financial results for the first quarter ended March 31, 2026, and provided a business update.
“We are very encouraged by the progress made across both our clinical and corporate priorities during the first quarter of 2026, including two partial responses observed in the ACESOT-1051 trial evaluating APR-1051. One of these has been confirmed at a second imaging assessment and this patient remains on study,” said Oren Gilad, Ph.D., President and Chief Executive Officer of Aprea. “These efficacy results, coupled with the encouraging tolerability, support our precision medicine strategy and reinforce the potential of targeted therapies for patients who have limited treatment options. We look forward to presenting an update from ACESOT-1051 at ASCO 2026 and providing additional insight into APR-1051’s emerging clinical profile. The recent
Key Business Updates and Upcoming Key Milestones
ACESOT-1051: A Biomarker Focused, Phase 1 Trial of Oral WEE1 inhibitor, APR-1051
- APR-1051 is a potent and selective, oral small molecule WEE1 inhibitor designed to potentially address therapeutic window limitations observed with earlier WEE1 programs. APR-1051 is being evaluated as monotherapy in uterine serous carcinoma patients regardless of mutation, cyclin E-overexpressing platinum-resistant ovarian cancer, advanced solid tumors harboring CCNE1, CCNE2, PPP2R1A or FBXW7 mutations, colorectal cancer harboring KRAS & TP53 mutations and HPV+ head and neck squamous cell carcinoma. These patient populations are associated with poor prognosis and limited effective treatment options.
- To date, two patients in ACESOT-1051 have achieved partial responses (“PR”). One uterine carcinosarcoma patient with PPP2R1A-mutation treated at the 220 mg dose level achieved a
50% reduction in target lesion size per RECIST v1.1 criteria and a significant reduction in CA-125 levels at the first imaging assessment. At the confirmatory, second imaging assessment, an additional9.5% reduction in target lesion size was observed, along with a further decline in CA-125 to 40.2 U/mL from 362 U/mL at baseline. This patient remains on study with an ongoing PR. There has also been an unconfirmed PR in a second patient with PPP2R1A-mutated uterine serous carcinoma, treated at the 150 mg dose level. - A total of 28 patients have been treated in ACESOT-1051 to date at doses ranging from 10 mg to 300 mg once daily. Six patients have achieved best overall response of stable disease, including patients with colorectal cancer, HPV+ head and neck squamous cell carcinoma, and endometrial cancer.
- Dose escalation is ongoing with enrollment currently underway in the 300 mg cohort (dose level 9). Additional eligible patients will be backfilled at 220 mg to further characterize safety, tolerability, and clinical activity, once dose level 9 is fully enrolled.
- APR-1051 has been shown to be well tolerated; the two most common adverse events have been Grade 1 or 2 nausea and fatigue. No treatment-related class-limiting toxicities, including severe myelosuppression or severe gastrointestinal toxicity, have been observed to date.
- Supported by the
$30 million financing that closed on March 31, 2026, Aprea is expanding enrollment in ACESOT-1051 to include at least 50 patients with uterine serous carcinoma (USC), as well as patients with cyclin E-overexpressing, platinum-resistant ovarian cancer (PROC). The expansion is intended to provide additional safety, tolerability and preliminary efficacy data to inform the future clinical path for APR-1051. Completion of dose escalation is anticipated in the second quarter of 2027. - Further clinical updates from ACESOT-1051 are expected during Q2 2026. An abstract entitled “Early results from the first-in-human phase 1 study of WEE1 inhibitor APR-1051 in patients with advanced solid tumors (ACESOT-1051)” has been accepted for the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting. The poster will be presented on May 30, 2026, 1:30 – 4:30pm CT.
- For more information on ACESOT-1051, refer to ClinicalTrials.gov NCT06260514.
ABOYA-119: Clinical Trial Evaluating ATR inhibitor, ATRN-119
- ATRN-119 is a potent and highly selective first-in-class macrocyclic ATR inhibitor, designed and developed to be used in patients with tumors harboring mutations in DDR-related genes. Cancers with mutations in DDR-related genes represent a high unmet medical need. These patients often have a poor prognosis and currently lack effective therapeutics options.
- During 2025 Aprea established 1,100 mg once daily as the recommended Phase 2 dose (RP2D) in the ABOYA-119 clinical trial. The Company strategically paused further enrollment and has started an orderly wind-down of certain clinical trial site activities associated with the monotherapy, as the Company explores ATRN-119 in potential combination approaches that may unlock greater clinical benefit. The Company is currently in discussions with leading academic institutions to evaluate ATRN-119 in combination with radiation in HPV+ head and neck cancer. Additional investigator-led studies evaluating ATRN-119 with immuno-oncology therapies and antibody-drug conjugates are also being explored.
- For more information on ABOYA-119, please refer to clinicaltrials.gov NCT04905914.
Corporate
- On March 31, 2026, the Company closed an oversubscribed private placement, raising gross proceeds of
$30 million . The private placement was led by Soleus Capital with participation from other new investors, including Vestal Point Capital and Squadron Capital Management, existing investors and certain insiders of the Company. Net proceeds will be used for general corporate purposes and research and development expenses, including the addition of more patients with USC (regardless of mutation status) into the ACESOT-1051 study and expansion into cyclin E-overexpressing PROC patients. - In February 2026, the Company appointed Eugene (Gene) Kennedy, MD, as Chief Medical Advisor. Dr. Kennedy is a highly accomplished physician scientist and biopharmaceutical executive with more than 20 years of experience spanning oncology clinical development, regulatory strategy, and senior corporate leadership across public and private biotechnology companies.
