Nivolumab induced frequent responses with an acceptable safety profile for patients with classical Hodgkin lymphoma who progressed after both autologous hematopoietic stem cell transplantation (auto-HSCT) and brentuximab vedotin, according to a phase 2 study published in The Lancet Oncology.1

Researchers assessed the clinical benefit and safety of single-agent nivolumab for patients who failed both auto-HSCT and brentuximab vedotin in this single-arm study, in which 80 patients were enrolled. Participants received nivolumab at a dose of 3 mg/kg intravenously over 60 minutes every 2 weeks until disease progression, unacceptable toxicity, or death.

Results of the ongoing study showed that 66.3% (95% CI, 54.8-76.4) of the 80 patients achieved an objective response as assessed by an independent radiological review committee, at a median follow-up of 8.9 months.

The most common immunotherapy-related adverse events were fatigue (25%), infusion-related reaction (20%), and rash (16%). The most frequently reported grade 3 to 4 adverse events were neutropenia (5%) and increased lipase concentrations (5%); the most common serious adverse event was pyrexia (4%).

Although 3 patients died, no deaths were considered related to nivolumab therapy.
