Brentuximab Vedotin, Cyclosporine, and Verapamil Hydrochloride in Treating Patients With Relapsed or Refractory Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
This phase I trial studies the side effects and best dose of brentuximab vedotin and cyclosporine when given together with verapamil hydrochloride in treating patients with Hodgkin lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Brentuximab vedotin is a monoclonal antibody, brentuximab, linked to a toxic agent called vedotin. Brentuximab attaches to CD30 positive cancer cells in a targeted way and delivers vedotin to kill them. Immunosuppressive therapies, such as cyclosporine, may improve bone marrow function and increase blood cell counts. Verapamil hydrochloride may increase the effectiveness of brentuximab vedotin by overcoming drug resistance of the cancer cells. Giving brentuximab vedotin, cyclosporine, and verapamil hydrochloride may work better in treating patients with Hodgkin lymphoma.

Detailed Description
-----------------
PRIMARY OBJECTIVE: I. Evaluate the safety and tolerability of the combination of brentuximab vedotin (BV) plus MDR1 inhibitors cyclosporine (CsA)/verapamil hydrochloride (verapamil [VRP]). SECONDARY OBJECTIVES: I. Obtain estimates of overall response rate (ORR), complete response (CR) rate, and response duration in patients treated with the combination of BV plus CsA/VRP. II. Estimate overall and progression-free survival in patients treated with the combination of BV plus CsA/VRP. III. Characterize pharmacokinetics of plasma monomethyl auristatin E (MMAE) in cycle 1 (for expansion cohort only). OUTLINE: This is a dose-escalation study of brentuximab vedotin and cyclosporine. Patients receive cyclosporine orally (PO) twice daily (BID) on days 1-5, verapamil hydrochloride PO four times daily (QID) on days 1-5, and brentuximab vedotin intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients who have not progressed are followed up every 6 months until disease progression, start of a new lymphoma therapy, 2 years post treatment, or study completion, whichever is earlier. Patients who progress are followed up periodically.
