What was measured

PFS was defined as the time from first dose of study treatment to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. PD was assessed according to the revised response criteria for malignant lymphoma per Cheson et al. 2007. PD was the appearance of any new lesion, \>50% increase in the sum of product diameters (SPD) of ≥1 lymph node, or a \>50% increase in the longest diameter of a previous lymph node, lesions positron emission tomography (PET) positive if 18F-fluorodeoxyglucose (FDG)-avid lymphoma or PET positive prior to therapy for lymph nodes; \>50% increase from nadir in the SPD of previous lesions in the liver and spleen; or new or recurrent involvement of the bone marrow. PFS was calculated from the Kaplan-Meier method for censored data. PFS as assessed by the investigator is presented.

Analysis population: All participants pooled from Cohort 5 (pembrolizumab + 20 or 25 mg doses of lenalidomide) with a baseline efficacy evaluation and at least 1 post-baseline efficacy evaluation. The analysis was pre-specified to be a pooled analysis of all participants grouped by disease cohort (DLBCL) and treatment combination (irrespective of dose); therefore data by individual dose were not analyzed.

Groups in this outcome

Pooled Cohort 5 (Pembrolizumab + 20 or 25 mg Doses of Lenalidomide)

Participants from the pooled Cohort 5 received pembrolizumab 200 mg by IV infusion on Day 1 of each 21-day cycle + lenalidomide 20 mg or 25 mg PO QD for 21 consecutive days with 7 days off within 28-day cycles.
