Summary
Brief summary
The purpose of this study is to compare efficacy of coformulated favezelimab/pembrolizumab
(MK-4280A) with physician's choice chemotherapy of bendamustine or gemcitabine in
participants with PD-(L)1-refractory, relapsed or refractory classical Hodgkin Lymphoma. The
study will also assess the safety and tolerability of coformulated favezelimab/pembrolizumab.
The primary study hypotheses are that coformulated favezelimab/pembrolizumab is superior to
physician's choice chemotherapy with respect to progression-free survival (PFS) and overall
survival (OS).
