Carfilzomib, Pomalidomide, and Dexamethasone in Treating Patients with High-Risk Multiple Myeloma
This phase II trial studies how well carfilzomib, pomalidomide, and dexamethasone work in treating patients with high-risk multiple myeloma. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as pomalidomide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving carfilzomib, pomalidomide, and dexamethasone may work better in treating patients with multiple myeloma.

Trial Objectives and Outline
I. To determine the >= complete response (CR) rates with carfilzomib, pomalidomide and dexamethasone (CPD) consolidation and maintenance.
I. To determine the improved progression free survival (PFS) with CPD consolidation and maintenance among high-risk patients.
II. To determine the best response rates (very good partial response rate [VGPR], stringent complete response [sCR] rate) with CPD consolidation and maintenance.
II. To evaluate the safety of the CPD combination as consolidative and maintenance regimen.
III. To characterize safety in subjects who receive CPD consolidation and maintenance.
IV. To evaluate the duration of response (DOR).
V. To evaluate the overall survival (OS) in high-risk patients.
VI. To evaluate the minimal residual disease (MRD) detection with CPD consolidation and maintenance.
CONSOLIDATION: Patients receive carfilzomib intravenously (IV) over 30 minutes on days 1, 2, 8, 9, 15, and 16, pomalidomide orally (PO) daily on days 1-21, and dexamethasone PO daily on days 1, 2, 8, 9, 15, and 16. Treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity.
MAINTENANCE: Patients receive carfilzomib IV over 30 minutes on days 1, 8, and 15, pomalidomide PO daily on days 1-21, and dexamethasone PO daily on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months.
