Combination therapy for advanced gastric cancer

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the efficacy of a combination treatment involving pembrolizumab, olaparib, and paclitaxel for patients with recurrent or advanced gastric and gastro-esophageal junction cancer. Pembrolizumab is an immunotherapy that targets the PD-1 receptor, while olaparib is a PARP inhibitor that works to prevent cancer cell repair. The study aims to evaluate the safety and effectiveness of this combination in patients who have not responded to previous treatments. Participants will be monitored for disease progression and response to therapy based on established criteria.
