This study tested whether gimistotug in combination with other agents could help treat participants with non-small cell lung cancer (NSCLC) who were already treated with other anticancer agents, including anti-programmed cell death protein-1 (anti-PD-1) and anti-programmed cell death protein ligand-1 (anti-PD-L1) antibodies and platinum-based chemotherapy. The main goal of this study was to see if gimistotug could increase participant response to treatment, also called the overall response rate.
Only a portion of patients with advanced solid tumors have a durable response to currently available treatments. This represents an unmet medical need to develop improved therapeutic options. Combining immunotherapies with agents having different mechanism of action might improve outcomes for these patients.
This study was designed as a proof of concept to show that gimistotug-based combination treatment may be able to improve responses and clinical benefit in patients with NSCLC. Treatments in all cohorts was administered up to 36 cycles (approximately 2 years) until participants experienced no benefits, too many side effects, or withdrew consent.
