APG-157 in Locally Advanced Head and Neck Squamous Cell Carcinoma

22. června 2026 aktualizováno: Aveta Biomics, Inc.

A Multicenter, Randomized, Open-Label Phase 3 Study of APG-157 as Neoadjuvant Therapy or as Induction and Maintenance Therapy in Locally Advanced Head and Neck Squamous Cell Carcinoma

This Phase 3, multicenter, randomized, open-label study evaluates APG-157 in adults with newly diagnosed locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Two independently powered cohorts are enrolled based on treatment pathway. Cohort A evaluates APG-157 administered as neoadjuvant therapy before curative-intent surgery in participants with resectable oral cavity or oropharyngeal cancer who are medically ineligible for perioperative pembrolizumab. Cohort B evaluates APG-157 administered as induction therapy before definitive chemoradiotherapy and as maintenance therapy after chemoradiotherapy in participants with unresectable or medically inoperable disease. Participants are randomized 1:1 within each cohort to receive APG-157-based treatment or standard-of-care therapy. The primary hypothesis is that APG-157 given before definitive surgery followed by (chemo)radiotherapy improves event-free survival (EFS) compared to surgery and adjuvant (chemo)radiotherapy alone (Cohort A), and that APG-157 given as induction therapy prior to definitive chemoradiotherapy (CRT) followed by maintenance APG-157 improves EFS compared to definitive CRT alone (Cohort B).

Detailní popis

This Phase 3, multicenter, randomized, open-label study evaluates APG-157 in adults with newly diagnosed locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The study consists of two independently powered cohorts designed to evaluate APG-157 in distinct treatment settings. Cohort A enrolls participants with resectable oral cavity or oropharyngeal squamous cell carcinoma who are objectively medically ineligible for perioperative pembrolizumab according to protocol-defined criteria. Participants are randomized 1:1 to receive APG-157 administered orally at 600 mg/day for 6 weeks prior to curative-intent surgical resection followed by protocol-directed adjuvant therapy, or standard-of-care surgery followed by adjuvant therapy alone. Cohort B enrolls participants with unresectable or medically inoperable locally advanced oropharyngeal squamous cell carcinoma. Participants are randomized 1:1 to receive APG-157 induction therapy for 4 weeks before definitive chemoradiotherapy, followed by APG-157 maintenance therapy initated within 60 days after chemoradiotherapy and continued for up to 1 year, or standard-of-care definitive chemoradiotherapy alone.The primary objective is to determine whether APG-157-based treatment improves event-free survival compared with standard-of-care treatment. Key secondary objectives include overall survival, objective response, pathological response, ctDNA clearance, safety, treatment feasibility, and patient-reported outcomes.

Časové okno
Event-Free Survival (EFS)
Časové okno: From randomization until the first occurrence of a protocol-defined EFS event, death, withdrawal from study follow-up, or study completion, assessed for up to approximately 36 months.

EFS is defined as the time from randomization to the earliest occurrence of a protocol-defined EFS event, including radiographic and/or clinical disease progression that precludes initiation or completion of planned definitive curative-intent therapy; locoregional recurrence, progression, or distant metastasis following definitive treatment, confirmed by imaging, pathology, salvage intervention with viable tumor or other protocol-defined assessments, where applicable, or death from any cause.

EFS will be analyzed by blinded independent central review (BICR) using RECIST v1.1 and protocol-defined pathology criteria, as applicable. The primary analysis will be conducted in the intent-to-Treat ( ITT) population using stratified log-rank testing and Cox proportional hazards models.

From randomization until the first occurrence of a protocol-defined EFS event, death, withdrawal from study follow-up, or study completion, assessed for up to approximately 36 months.
