Retrospective Observational Study in Patients With Relapsed / Refractory Primary Mediastinal Lymphoma Treated With Pembrolizumab or Nivolumab in Combination With Brentuximab Vedotin in a Real-life Context

Observational, Non-Interventional, Retrospective, Multicenter Study Focusing on the Efficacy and Safety of Pembrolizumab Monotherapy and Nivolumab in Combination With Brentuximab Vedotin in Clinical Practice Patients With Primary Mediastinal B Cell Lymphoma Relapsed/Refractory

Observational, non-interventional, retrospective, multicentre study focusing on the efficacy and safety of pembrolizumab as monotherapy and nivolumab in combination with brentuximab vedotin in daily clinical practice in patients with Primary Mediastinal B Cell Lymphoma Relapsed/Refractory. The study aims to retrospectively evaluate the efficacy in terms of overall response rate (ORR, sum of complete response rate [CR] and partial response rate [PR]) of pembrolizumab as a single agent and nivolumab in combination with brentuximab vedotin in patients with Primary Mediastinal B Cell Lymphoma Relapsed/RefractoryL treated in a real-life setting from November 2020 until November 2021.

Secondary objectives

• To assess efficacy, in terms of:
• Duration of response (DoR)
• Progression-free survival (PFS)
• Overall survival (OS)
• Disease-free survival (DFS)
• Best response rate (achieved at any time during treatment)
• To evaluate the safety and tolerability of pembrolizumab as a single agent and nivolumab in combination with brentuximab vedotin The study will include patients with Primary Mediastinal B Cell Lymphoma Relapsed/Refractory treated with pembrolizumab as a single agent and nivolumab in combination with brentuximab vedotin in a real-life setting from November 2020 until November 2021.
