Study of Brentuximab Vedotin as Therapy After Autologous Stem Cell Transplant in Cluster of Differentiation Antigen 30 (CD30) Positive Peripheral TCell Lymphomas

For participants with CD30 positive Mature T-cell lymphomas who have received brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone (A-CHP) as induction (4 to 6 cycles) and achieved complete response (CR) or chemo-sensitive partial response (PR) and deemed suitable for autologous stem cell transplant (ASCT) as consolidation, the investigators propose to add brentuximab vedotin after ASCT. There is currently no standard of care treatment to prevent relapse after upfront treatment or ASCT for CD30-positive peripheral T-cell lymphoma's (PTCL)s. An agent that could improve outcomes in this population would be a major contribution to the field and is likely to be practice changing. Therefore, in addition to studying the anti-lymphoma activity of A-CHP as induction therapy, for participants who respond to induction the investigators propose to add brentuximab vedotin consolidation after ASCT in participants treated with consolidative upfront ASCT.
