---

Brief description of study

This study will evaluate the safety and efficacy of MK-4280 in combination with pembrolizumab (MK-3475) in participants with hematological malignancies:

• classical Hodgkin lymphoma (cHL)
• diffuse large B-cell lymphoma (DLBCL)
• indolent non-Hodgkin lymphoma (iNHL) The study will have 2 phases: a safety lead-in and an efficacy expansion phase. The recommended Phase 2 dose (RPTD) will be determined in the safety lead-in phase by evaluating dose-limiting toxicities.
