Phase 1: Carfilzomib will be administered as a 30-minute intravenous (IV) infusion on Days 1, 8, and 15 of each 28-day cycle. On only Day 1 of Cycle 1, all patients will receive carfilzomib at 20 mg/m2. All subsequent carfilzomib doses (45, 56, 70 or 88 mg/m2) will be administered according to the dose assignment for each cohort.
Phase 2: using the MTD established for carfilzomib from the Phase 1 portion of the study (except on Cycle 1 Day 1 the carfilzomib dose will be 20 mg/m2); this arm will be administered drug on the same schedule as in Phase 1.
This Phase 1/2 study in patients with progressive multiple myeloma is designed to achieve the following: to determine the MTD of carfilzomib and dexamethasone administered once weekly (Cd-qw) for 3 consecutive weeks in a 28-day cycle and to determine the magnitude of responses achieved in patients treated with the MTD.
The Cd-qw dosing schedule proposed in this protocol may be beneficial from a patient convenience perspective compared to the twice-weekly dosing schedule, however, as the clinical benefit and safety of weekly carfilzomib administration has not been assessed in multiple myeloma patients, patients who progress on weekly carfilzomib will be allowed 1 attempt to recapture response by increasing the dose frequency to the twice-weekly carfilzomib dosing schedule that has demonstrated efficacy and tolerability. This information will be valuable in assessing the dose intensity impact on the suppression of multiple myeloma in the relapsed setting.
Finally, this protocol will eliminate the requirement for fluid administration with carfilzomib after Cycle 1 and will reduce the time that is required to treat the patient in clinic. This modification will be studied for its effect on the carfilzomib safety profile.
