Summary
Brief summary
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.
