Brentuximab Vedotin and Pembrolizumab Combination in Patients with Relapsed/Refractory Hodgkin Lymphoma: A Single-Centre Retrospective Analysis

Classical Hodgkin lymphoma (HL) patients presenting a relapsed/refractory (R/R) disease are currently managed with salvage chemotherapy followed by autologous stem cell transplantation (ASCT). However, almost 25–30% of these patients fail to achieve a complete response (CR) with standard salvage regimens. In this retrospective study, we evaluated the efficacy of a combination of brentuximab vedotin (BV) and pembrolizumab in a series of HL patients presenting with a high-risk, multi-refractory disease. Patients achieving a Deauville score ≤4 proceeded to ASCT consolidation. After ASCT, patients received BV as maintenance for a total of 16 administrations. We collected data from 10 patients with a median age of 30.7 years. At a median follow-up of 16.5 months, we reported a complete metabolic remission (CMR) in eight patients (80%), with seven patients (70%) directly proceeding to ASCT (the other two patients in CMR are still undergoing treatment). BV consolidation was started in six patients and completed by three patients (one ongoing, two interruption). Two patients (20%) presented a progressive disease (PD) and subsequently died, while the others are still in CMR. The BV and pembrolizumab combination is a very effective bridge treatment to ASCT for high-risk R/R HL patients.
