RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Thalidomide may stop the growth of cancer cells by blocking blood flow to the tumor. Giving combination chemotherapy together with carfilzomib and thalidomide may kill more cancer cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of carfilzomib when given together with cyclophosphamide, thalidomide, and dexamethasone in treating patients with newly diagnosed active multiple myeloma.

Detailed Description:


I. To establish the maximum tolerated dose of carfilzomib given in combination with oral cyclophosphamide and thalidomide and dexamethasone. (Phase I) II. In newly diagnosed myeloma to evaluate the response rate (CR, nCR, and VGPR) to carfilzomib given in combination with oral cyclophosphamide and thalidomide and dexamethasone after four 28 day cycles. (Phase II)


I. Determine the overall response rate (CR, nCR, PR) after 4, 8, 12 cycles. II. Determine the duration of progression-free and overall survival for patients receiving this regimen.

III. To evaluate the incidence of toxicities for this regimen. IV. To evaluate the ability to successfully collect peripheral blood stem cells following four months of combination therapy.

OUTLINE: This is a phase I, dose escalation study of carfilzomib followed by a phase II study.

Patients receive carfilzomib IV on days 1, 2, 8, 9, 15, and 16; oral cyclophosphamide on days 1, 8, and 15; oral dexamethasone on days 1, 8, 15, and 22; and oral thalidomide on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at 3 months, then every 3 months for 1 year, and then every 6 months for up to 3 years.
