Master protocol: The main goal of this master clinical study is to evaluate the efficacy and safety of multiple novel combination therapies in participants with head and neck squamous cell carcinoma (HNSCC) in various substudies. Substudy-01 will evaluate the efficacy and safety of novel combination of treatment regimens, domvanalimab (DOM) and zimberelimab (ZIM) combined with chemotherapy vs ZIM combined with chemotherapy. The primary objective is to assess the efficacy of DOM and ZIM in combination with chemotherapy versus ZIM in combination with chemotherapy.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Gilead Sciences (GILD) is the sponsoring company for this trial. BiotechSign currently grades this company F (28/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
