Brief Summary

This is an open-label, multi-center, single arm, phase II study to assess the anti-tumor activity and safety of bemcentinib in combination with pembrolizumab in up to 106 participants with previously treated, advanced adenocarcinoma of the lung. The study will enrol three cohorts of participants with previously treated, advanced adenocarcinoma of the lung. Cohort A will consist of participants who received a maximum of 1 prior line of platinum-containing chemotherapy and no prior immunotherapy. Cohort B will consist of participants who received a maximum of one prior line of an anti-programmed death receptor (PD)-(L)1 therapy (monotherapy). Cohort C will consist of participants who received a maximum of one prior line of therapy with an anti-PD-(L)1 therapy in combination with a platinum-containing chemotherapy. The primary objective is to assess the anti-tumor activity of bemcentinib in combination with pembrolizumab.
