Daratumumab, Ixazomib, Pomalidomide, and Dexamethasone in Treating Patients with Multiple Myeloma That Has Come Back or Does Not Respond to Treatment

Status: Active


This phase II trial studies the side effects and best dose of daratumumab, ixazomib, pomalidomide, and dexamethasone, and how well they work in treating patients with multiple myeloma that has come back or does not respond to treatment. Drugs used in chemotherapy, such as daratumumab, ixazomib, pomalidomide, and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may work better in treating patients with multiple myeloma.

Trial Objectives and Outline


I. To determine the overall response rate (ORR) including stringent complete response (sCR), complete response (CR), very good partial response (VGPR), and partial response (PR) of daratumumab, ixazomib, pomalidomide, and dexamethasone (D-IPd) therapy based on International Myeloma Working Group (IMWG) criteria.

II. To evaluate the safety and tolerability of ixazomib in combination with daratumumab, pomalidomide and dexamethasone, which will include treatment-emergent Grade 2-5 adverse events (AEs) defined using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version (v) 4.03 toxicity criteria attributable to study therapy.


I. To determine the clinical benefit rate (CBR: minimal response + ORR).

II. To determine Progression Free Survival (PFS), Time to Progression (TTP) and Overall Survival (OS).

III. To determine the percent Minimal Residual Disease (MRD) negativity.

IV. To determine response rates and PFS of patients based on their risk cytogenetics/fluorescence in situ hybridization (FISH) (t[4;14]; t[14;16]; del 17p).

V. To assess the effects of D-IPd on quality of life (QOL) using Cancer Therapy Satisfaction Questionnaire and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Myeloma (MY) 20.


Patients receive daratumumab intravenously (IV) for 1.5 to 6.5 hours on days 1, 8, 15, and 22 of courses 1 and 2, on days 1 and 15 of courses 3-6, and on day 1 of subsequent courses, ixazomib orally (PO) on days 1, 8, and 15, pomalidomide PO once daily (QD) on days 1-21, and dexamethasone PO on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 1 year.
