Therapy of patients with relapsed and refractory classic Hodgkin lymphoma (r/r cHL) after PD-1 inhibitors failure remains an unresolved issue. The aim of this study was to evaluate the efficacy and safety of the combination of nivolumab with brentuximab vedotin (Nivo + BV) after nivolumab monotherapy failure.This study retrospectively analyzed 21 patients with r/r cHL who were treated with the combination of Nivo + BV after Nivo failure. The response was evaluated by PET-CT scan according to the LYRIC criteria. Adverse events (AEs) were assessed according to NCI CTCAE v.4.03.Median follow-up was 19 (9-47) months. The ORR was 57%. The median OS was not reached, 24 month OS was 80% (95% CI 50-93%). Median PFS was 12 months with 24 month PFS of 31% (95% CI 12-53%). Any grade AEs were observed in 12 patients (63%), 3-4 grade AEs in 2 patients (10%). Allogeneic hematopoietic stem cell transplantation (allo-HSCT) after Nivo + BV was performed in 8 (38%) patients. The median time between Nivo + BV and allo-HSCT was 8 (5-21) months.Combination of Nivo + BV in r/r cHL after nivolumab monotherapy failure is potentially an effective and safe approach.
