Official title
A Phase 1/Phase 2 Clinical Study to Evaluate the Safety and Efficacy of a Combination of MK-4280 and Pembrolizumab (MK-3475) in Participants With Hematologic Malignancies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate the safety and efficacy of favezelimab (MK-4280) in combination with pembrolizumab (MK-3475) using a non-randomized study design in participants with the following hematological malignancies: * classical Hodgkin lymphoma (cHL) * diffuse large B-cell lymphoma (DLBCL) * indolent non-Hodgkin lymphoma (iNHL) This study will also evaluate the safety and efficacy of pembrolizumab or favezelimab administered as monotherapy in participants with cHL using a 1:1 randomized study design. The study will have 2 phases: a safety lead-in and an efficacy expansion phase. The recommended Phase 2 dose (RP2D) will be determined in the safety lead-in phase by evaluating dose-limiting toxicities. There is no primary hypothesis for this study.
