Brentuximab vedotin and bendamustine: an effective salvage therapy for relapsed or refractory Hodgkin lymphoma patients.

ABSTRACT

The prognosis is poor for relapsed or refractory (R/R) classical Hodgkin Lymphoma (cHL) patients. The brentuximab vedotin (Bv) and bendamustine (B) combination has been used as a preferable salvage regimen in R/R cHL patient trials. We retrospectively evaluated response rates, toxicities, and the survival in R/R cHL patients treated with the BvB combination. In a multi-centre real-life study, 61 R/R HL patients received intravenous doses of 1.8 mg/kg Bv on the first day plus 90 mg/m2 B on the first and second days of a 21-day cycle as a second-line or beyond-salvage regimen. Patients' median age at BvB initiation was 33 (range 18-76 years). BvB was given as median third-line treatment for a median of four cycles (range 2-11). The overall and complete response rates were 82% and 68.9%, respectively. After BvB initiation, the median follow-up was 14 months, and one- and two-year overall survival rates were 85% and 72%, respectively. Grade 3/4 toxicities included neutropenia (24.6%), lymphopenia (40%), thrombocytopenia (13%), anaemia (13%), infusion reactions (8.2%), neuropathy (6.5%), and others. The BvB combination could be given as salvage regimen aiming a bridge to autologous stem cell transplant (ASCT), in patients relapse after ASCT or to transplant-ineligible patients with manageable toxicity profiles.
