Time frame
From registration to disease progression while receiving ixazomib citrate and dexamethasone, death due to any cause, or subsequent treatment for multiple myeloma, assessed up to 2.5 years

What was measured

Date of progression will be defined as the date that the criteria for progressive disease were first met after initiation of dexamethasone. The distribution of event-free survival will be estimated using the method of Kaplan-Meier.

Groups in this outcome

Arm A (Ixazomib Citrate and Dexamethasone)

Patients receive ixazomib citrate PO on days 1, 8, and 15. Patients with lack of minor response by the end of the second cycle or lack of partial response by the end of the fourth cycle also receive dexamethasone PO on days 1, 2, 8, 9, 15, and 16. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Arm B (Ixazomib Citrate and Dexamethasone)

Patients receive ixazomib citrate PO on days 1, 8, and 15 and dexamethasone PO on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Arm C (Higher-dose Ixazomib Citrate and Dexamethasone)

Patients receive higher doses of ixazomib citrate PO on days 1, 8, and 15 and dexamethasone PO on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Arm D (Ixazomib Citrate, Dexamethasone, and Cyclophosphamide)

Patients receive ixazomib citrate PO on days 1, 8, and 15 and cyclophosphamide PO (cycles 1-18 only) and dexamethasone PO on days 1, 8, 15, and 22. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Arm E (Ixazomib Citrate, Cyclophosphamide, Daratumumab)

Patients receive ixazomib citrate PO on days 1, 8, and 15, cyclophosphamide PO (cycles 1-12 only) on days 1, 8, 15, 22, and daratumumab IV on days 1, 8, 15, 22 (cycles 1-2), days 1 and 15 (cycles 3-6), and day 1 in all subsequent cycles. Patients also receive dexamethasone IV or PO on days 1, 8, 15, and 22. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
