GSK is advancing both arms of the COSTAR Lung trial into phase III. The decision follows the recommendation of the Independent Data Monitoring Committee, given that the trial met its pre-specified expansion criteria per protocol

The COSTAR Lung phase III trial is a randomized, open label 3-arm trial comparing cobolimab, an investigational selective anti–TIM-3 monoclonal antibody, plus dostarlimab plus docetaxel to dostarlimab plus docetaxel to docetaxel alone in patients with advanced NSCLC who have progressed on prior anti-PD-(L)1 therapy and chemotherapy.

Hesham Abdullah, Senior Vice President, Global Head of Oncology Development, GSK said: “These trials support the ambition for dostarlimab to become the backbone of our ongoing immuno-oncology-based research and development programme when used alone and in combination with standard of care and future novel cancer therapies, particularly in patients with currently limited treatment options.”

The COSTAR Lung trial is a phase II/III global, randomized, open-label trial of 750 patients. The study evaluates the efficacy and safety of cobolimab plus dostarlimab plus docetaxel and dostarlimab plus docetaxel compared to docetaxel in patients with advanced non-squamous and squamous NSCLC whose disease had progressed on prior therapy with an anti-PD-(L)1 agent and a platinum doublet-based chemotherapy given in combination or in sequence. The study does not include patients with a known sensitizing epidermal growth factor receptor, anaplastic lymphoma kinase, or receptor tyrosine kinase-1 mutation, for which an approved targeted therapy is available. The primary endpoint is overall survival.
