What was measured

OS was defined as the time from the first dose to death due to any cause. OS is presented from product limit (Kaplan-Meier) method for censored data (censored at the last assessment).

Analysis population: The analysis population included all participants who received at least one dose of study medication (pembrolizumab).

Groups in this outcome

Pembrolizumab: Relapsed or Refractory Primary Mediastinal Large B-cell Lymphoma (rrPMBCL)

Pembrolizumab 200 mg every 3 weeks (Q3W), intravenous infusion (IV) on Day 1 of each 3-week cycle for up to 35 administrations (approximately 2 years).

Pembrolizumab: Relapsed or Refractory Richter Syndrome (rrRS)

Pembrolizumab 200 mg Q3W, IV on Day 1 of each 3-week cycle for up to 35 administrations (approximately 2 years).
