Study of Carfilzomib for Multiple Myeloma Patients Who Are Relapsed/Refractory to Bortezomib-containing Treatments

Summary

This is a phase I/II multicenter, open label, nonrandomized study for patients with Multiple Myeloma (MM) who will receive treatment with carfilzomib in place of bortezomib using the same bortezomib-containing combination regimen to which a MM patient has progressed while receiving. This study will enroll 45 patients total. These patients will be resistant to bortezomib as demonstrated by progressive disease while on bortezomib or have relapsed within 12 weeks of the last dose of bortezomib in a combination regimen. Patients will be sub-divided into 2 groups in this study, treatments containing (Group A) or not containing immunomodulatory drugs (IMiDs) (Group B). Thirty patient will be enrolled into Group A and 15 patients into Group B for a total of 45 patients. Patients must have received 4 doses of a minimum of 1.0 mg/m\^2 of bortezomib in no more than 4 weeks per cycle. Patients must have received at least one cycle meeting this definition and have shown progressive disease to be considered eligible. Patients who have been refractory to or relapsed within 12 weeks of the last dose of bortezomib in their most recent bortezomib-containing regimen that does not include either thalidomide or lenalidomide are eligible regardless of when patients received that regimen, as long as they meet the above criteria.

Carfilzomib will subsequently replace bortezomib using the patient's most recent bortezomib-containing regimen to which the patient progressed while receiving. Patients will be eligible if they progressed from bortezomib with an alkylating agent (melphalan or cyclophosphamide), an anthracycline (doxorubicin or pegylated liposomal doxorubicin) and/or a glucocorticosteroid (prednisone, dexamethasone or medrol)and IMiD (thalidomide or lenalidomide). The study will consist of a screening period, followed by up to eight open label treatment cycles, a final assessment to occur 28 days after the end of the last treatment cycle, a follow-up period and maintenance cycles of single agent carfilzomib.

Patient who complete the combination treatment period without progressive disease will be eligible for maintenance therapy with single-agent carfilzomib. During maintenance therapy carfilzomib will be administered at the same dose given during the last cycle of combination treatment.

Conditions

• Multiple Myeloma

Interventions

DRUG

Group A: Carfilzomib & Non-IMiD Regimen

Carfilzomib will be administered intravenously starting at a dose of 20 mg/m\^2 over 30 minutes for the first cycle and will then be increased to 27, 36 and 45 mg/m2 during cycles 2-4, respectively. Doses will be administered IV once daily on days 1, 2, 8, 9, 15, and 16 of each cycle. Cycles will be 28 days in length. Combination non-IMiD drug is dosed on the identical schedule and dosage as patient was in previous bortezomib containing regimen. Maintenance regimen maybe administered if patient does not progress while on study.

DRUG

Group B: Carfilzomib & IMiD containing regimen.

Carfilzomib will be administered intravenously starting at a dose of 20 mg/m\^2 over 30 minutes for the first cycle and will then be increased to 27, 36 and 45 mg/m2 during cycles 2-4, respectively. Doses will be administered IV once daily on days 1, 2, 8, 9, 15, and 16 of each cycle. Cycles will be 28 days in length. Combination IMiD drug is dosed on the identical schedule and dosage as patient was in previous bortezomib containing regimen. Maintenance regimen maybe administered if patient does not progress while on study.
