Study to Evaluate the Safety and Efficacy of a Combination of Favezelimab (MK-4280) and Pembrolizumab (MK-3475) in Participants With Hematologic Malignancies (MK-4280-003)
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- Percentage of Participants Experiencing a Dose-limiting Toxicity (DLT) [Cycle 1 (up to 21 days)]
DLT will be defined as any drug-related adverse event (AE) observed during the DLT evaluation period (Cycle 1) that results in a change to a given dose or a delay in initiating the next cycle and reported as the percentage of participants experiencing a DLT defined by the National Cancer Institute Common Terminology for Adverse Events version 4.0.
- Percentage of Participants Experiencing an Adverse Event (AE) [From time of signing informed consent form (ICF) until the end of follow-up (up to approximately 27 months)]
Percentage of participants experiencing an AE defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study therapy and irrespective of causality to study treatment
- Percentage of Participants with Treatment Discontinuations Due to an AE [From time of signing informed consent form (ICF) until the end of study treatment (up to approximately 24 months)]
Percentage of participants discontinuing study treatment due to an AE
Secondary Outcome Measures
- Objective Response Rate (ORR) [Up to approximately 24 months]
ORR is defined as the percentage of participants in the analysis population who had a Complete Response or a Partial Response per lymphoma disease response criteria (Cheson et. al., 2007) as assessed by the investigator.
- Serum Concentration of Favezelimab [At designated time points (Up to approximately 25 months)]
Blood samples will be collected at designated time points for the determination of the serum concentration of favezelimab. For Cycles 1 and 8: Day 1 at predose, end of infusion, and 4 hours postdose; Days 8 and 15 at any time. Cycles 2 through 7, Cycles 9 through 16 and every 4 cycles thereafter: Day 1 at predose. Blood samples will also be collected at the 30-day follow-up visit.
- Serum Concentration of Pembrolizumab [At designated time points (Up to approximately 25 months)]
Blood samples will be collected at designated time points for the determination of the serum concentration of pembrolizumab. For Cycles 1 and 8: Day 1 at predose, end of infusion, and 4 hours postdose; Days 8 and 15 at any time. Cycles 2 through 7, Cycles 9 through 16 and every 4 cycles thereafter: Day 1 at predose. Blood samples will also be collected at the 30-day follow-up visit.
