International Phase III Study of Durvalumab with Domvanalimab Versus Durvalumab with Placebo in Adults with Stage III Unresectable Non-Small Cell Lung Cancer After Platinum-Based Chemoradiation

What this Trial Is About

Researchers are evaluating the efficacy and safety of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced Stage III, unresectable non-small cell lung cancer NSCLC whose disease has not progressed after definitive platinum-based concurrent chemoradiotherapy cCRT. This Phase III, randomized, double-blind, placebo-controlled, international study aims to provide new insights into treatment options for this patient population. Participants will receive either durvalumab and domvanalimab or durvalumab plus placebo as intravenous infusions every four weeks, beginning on Day 1 and continuing for up to 12 months. The study includes two groups one receiving the combination of durvalumab and domvanalimab, and the other receiving durvalumab with a placebo. Both treatments are given through infusion to assess their effects on disease progression and safety. During the trial, participants will undergo regular assessments including monitoring progression-free survival for up to 8 years after randomization. Other measures include overall survival, response rates, duration of response, and various time-to-event outcomes related to disease progression and symptom deterioration. Researchers will also evaluate drug concentrations and immune responses approximately 12 weeks after the last dose. Participants can expect scheduled visits for infusions and evaluations as part of this long-term study.
