Abstract

Objective: The aim of the present study was to compare the effects of nivolumab bridge to allogeneic hematopoietic stem cell transplantation (allo-SCT) on progression-free survival (PFS) and overall survival (OS) and toxicity profile. Patients and Methods: The study population consisted of relapsed/refractory cases of HL, who were treated with nivolumab for disease control and subsequently underwent allo- SCT at our institution. The control group consisted of HL patients who relapsed or refractory after multiple lines of therapy and underwent allo-SCT without nivolumab before transplantation as bridging therapy. Results: The incidence of acute and chronic graft vs. host disease (GVHD) was similar in both groups. The 100-day mortality occurred in 1 patient (10%) in the nivolumab group and 4 patients (16.7%) in the control group (p = 0.54). During 30-month follow-up, PFS was achieved in 60% of patients in the nivolumab group and 45.8% in the control group (p = 0.69). OS during 30-month follow-up was 80% in the nivolumab group and 41.7% in the control group, OS was superior in patients in the nivolumab group than in the control group (p = 0.04). Conclusions: Allo-SCT after bridging therapy with nivolumab provides a survival advantage over patients who underwent allo-SCT without the bridging. Therapy with nivolumab in combination with post-transplant cyclophosphamide does not appear to increase GVHD.
