Randomized Phase II, Open-label Efficacy and Safety Study of Second-line Durvalumab Plus Tremelimumab Versus Platinum-based Chemotherapy Alone in Patients With NSCLC and First-line Checkpoint-inhibitor Therapy (Re-Check)

• Status: Recruiting
• Trial end date: 2026-05-01

Summary

This is an open label, randomized, Phase II multicenter study designed to evaluate the safety and efficacy of two different second-line strategies: After failure of first line mono-immunotherapy with checkpoint inhibitors (anti-PD-1/PD-L1), and subsequent 2 cycles of standard of care platinum-based chemotherapy, 2 treatment arms will be compared: Arm A (Experimental Arm): After randomization, patients will receive a combination regimen featuring a single, priming dose of tremelimumab together with conventional durvalumab dosing. Durvalumab maintenance therapy will subsequently be continued as study treatment for up to 12 cycles.

Arm B: After randomization, patients will continue to receive another 2-4 cycles of platinum-based chemotherapy. Afterwards, patients will end treatment or receive maintenance pemetrexed therapy as per marketing authorization (depending on histology, maximum of 13 cycles) at the discretion of the investigator
