A Study of Brentuximab Vedotin Combined With Nivolumab for Relapsed or Refractory Hodgkin Lymphoma

This study will examine the safety profile and antitumor activity when brentuximab vedotin is combined with nivolumab. Patients will be treated for up to four 21-day cycles with brentuximab vedotin 1.8 mg/kg and nivolumab 3 mg/kg. There will be 3 parts to this study. In Part 1, the safety of combination treatment will be evaluated by a Safety Monitoring Committee (SMC) prior to expansion of enrollment to evaluate treatment effect in Part 2. Part 2 of the study will further characterize the safety and antitumor activity of brentuximab vedotin combined with nivolumab by enrolling patients at the recommended dose schedule determined in Part 1. Part 3 of the study will evaluate the safety and antitumor activity of combination treatment administered at an alternate dosing schedule determined by cumulative safety and activity data from Parts 1 and 2.
