Brentuximab Vedotin and Lenalidomide in Patients With Relapsed/ Refractory T-cell Lymphoma or Hodgkin Lymphoma

This study is investigating the combination of Brentuximab vedotin and lenalidomide in the treatment of relapsed/refractory peripheral T cell lymphoma or cutaneous T cell lymphoma or Hodgkin lymphoma. It is hypothesised that lenalidomide may augment the actions of Brentuximab vedotin in these patient groups. The primary objective of the study is to determine the maximum tolerated dose of the combination treatment, which can be used in subsequent studies. The study will also investigate disease response and survival. Participants will receive Brentuximab vedotin (once every 21 days i.e. 1 cycle) and lenalidomide (daily from day 1 -14 of each cycle) for a maximum of 48 weeks and will be followed for a subsequent 6 months after the end of treatment.
