Participant Group / Arm

Intervention / Treatment

EXPERIMENTAL: Carfilzomib and Dexamethasone; Phase 1: Carfilzomib will be administered at an escalating dose with dexamethasone administered at 8mg. Phase 2: Carfilzomib will be administered at the MTD determined in phase 1. Maintenance: Carfilzomib and dexamethasone will be administered in the same fashion as the previous treatment cycles, but only on days 1, 2, 15, and 16.

Drug: Carfilzomib and Dexamethasone; Phase 1: Carfilzomib will be administered at an escalating dose by cohort as 60-minute IV infusion on Days 1, 2, 8, 9, 15, and 16 of a 28-day cycle. On Cycle 1 Days 1 and 2, carfilzomib will be given at 20 mg/m^2. For all subsequent doses, carfilzomib will be administered at the dose assigned to the cohort (56, 70, or 88 mg/m^2). Dexamethasone (8 mg IV or PO) will be administered prior to carfilzomib on Days 1, 2, 8, 9, 15, and 16. Phase 2: Carfilzomib will be administered at the MTD determined in phase 1. Maintenance: From Cycle 9 onward, carfilzomib and dexamethasone will be administered in the same fashion as during the previous treatment cycle, but only on days 1, 2, 15, and 16.; Other Names: Krypolis®

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Establish maximum tolerated dose (MTD)	Maximum tolerated dose will be established by the number of dose limiting toxicities and the overall safety and tolerability of the study drug. Safety and tolerability will be determined by the following: incidence and frequency of adverse events throughout the study; clinical laboratory test results at study visits; vital signs measurements at each study visits; medical history and physical examination findings; ECOG performance status at study visits; concomitant medication usage throughout the study	monthly, up to 24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Establish efficacy as assessed by the overall response rate	Response rate will be determined by the following: SPEP, UPEP, and quantification of immunoglobulins and immunofixation; bone marrow aspirates and biopsies to confirm CR; roentgenographic skeletal survey Response rate will be assessed by the following: Clinical benefit response rate; Progression-free survival; Time to progression; Duration of response; Overall survival; Pharmacodynamics	monthly, up to 24 months

Other Outcome Measures

Outcome Measure	Time Frame
Relationship of 60-minute infusion of carflizomib with pharmacodynamic markers	weekly for 2 months
