Researchers are evaluating the efficacy and safety of volrustomig compared to observation in participants with unresected locally advanced head and neck squamous cell carcinoma LA-HNSCC who have not progressed after receiving definitive concurrent chemoradiotherapy cCRT. This phase III, randomized, open-label global study aims to assess whether volrustomig can improve outcomes in this patient population. Participants are randomly assigned to one of two groups those who receive volrustomig as sequential therapy, and those who undergo observation without additional treatment. The study compares these two approaches following prior curative concurrent chemoradiotherapy. The trial includes long-term follow-up to monitor patient outcomes. During the study, participants will be regularly assessed for progression-free survival, overall survival, physical functioning, and quality of life. Researchers will also monitor for the presence of anti-drug antibodies and adverse events related to volrustomig. Follow-up evaluations may continue for up to approximately eight years to fully understand the treatment impact and safety profile.
