Brief Summary

The purpose of this study is to determine the overall response rate of patients with Multiple Myeloma to the combination of Daratumumab, Ixazomib, Pomalidomide and Dexamethasone.

Detailed Description

The purpose of this study is to determine the overall response rate of patients with Multiple Myeloma to the combination of Daratumumab, Ixazomib, Pomalidomide and Dexamethasone.

The drugs being used in this study are daratumumab ixazomib, pomalidomide, and dexamethasone. Ixazomib may stop the growth of cancer by interfering with proteasomes (the protein breakdown mechanism in the cells). Pomalidomide, and dexamethasone are standard drugs that can change and regulate the immune system and may stop cancer cells from growing. Both Ixazomib and Daratumumab are approved for use in Multiple Myeloma, but not in this combination.

Conditions

Relapsed/Refractory Multiple Myeloma

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP

Study Groups

ixazomib, daratumumab, pomalidomide and dexamethasone

Daratumumab will be administered at 16mg/kg IV weekly x 8 weeks, biweekly x 8 weeks, then monthly. Pomalidomide 4mg will be administered orally daily for days 1-21. Patients ≤ age 75 will receive a 40mg dose of dexamethasone, and those over the age of 75 may receive a 20mg dose of dexamethasone orally on days 1, 8, 15, and 22 (weekly). Ixazomib will be administered 4mg orally on days 1, 8 and 15.
