Study Description

Brief Summary

This phase II trial studies how well ixazomib citrate works in treating patients with multiple myeloma that has returned after a period of improvement (relapsed) but is not resistant to bortezomib (refractory). Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVES:

To determine the confirmed overall response rate (>= partial response [PR]) of ixazomib [ixazomib citrate], used as a single agent in patients with relapsed multiple myeloma, who are proteasome inhibitor naive (including bortezomib) naive OR have received less than 6 cycles of therapy with bortezomib and had a better than PR with no progression at the time of discontinuation. (Arm A - Permanently closed to accrual as of Addendum 5) II. To determine the confirmed overall response rate (>= PR) of ixazomib at a 4 mg dose level in combination with dexamethasone in patients with relapsed multiple myeloma, who are proteasome inhibitor naive (including bortezomib) naive OR have received less than 6 cycles of therapy with bortezomib and had a better than PR with no progression at the time of discontinuation. (Arm

1. To determine the confirmed overall response rate (>= PR) of ixazomib at a 5.5 mg dose level in combination with dexamethasone in patients with relapsed multiple myeloma, who are proteasome inhibitor naive (including bortezomib) naive OR have received less than 6 cycles of therapy with bortezomib and had a better than PR with no progression at the time of discontinuation. (Arm C) IV. To determine the confirmed overall response rate (>= PR) of ixazomib in combination with cyclophosphamide and dexamethasone in patients with relapsed multiple myeloma, who are proteasome inhibitor naive (including bortezomib) naive OR have received less than 6 cycles of therapy with bortezomib and had a better than PR with no progression at the time of discontinuation.

To determine the event free survival and overall survival among patients with relapsed myeloma following treatment with ixazomib in combination with cyclophosphamide, daratumumab, and dexamethasone. (Arm E)

OUTLINE: Patients are randomized to 1 of 4 treatment arms (Arm A permanently closed to accrual as of Addendum 5).

ARM A: Patients receive ixazomib citrate orally (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: 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: Patients receive higher dose 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: 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: 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 intravenously (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.

After completion of study treatment, patients are followed up every 6 or 12 months for 2 years.

Outcome Measures

Primary Outcome Measures

Proportion of confirmed responses with ixazomib citrate alone (Arm A [closed]), ixazomib citrate with dexamethasone (Arms B + C), or with dexamethasone and cyclophosphamide (Arm D), or with dexamethasone, cyclophosphamide, daratumumab (Arm E) [Up to 2.5 years]
A confirmed response is defined as stringent complete response, complete response (CR), very good partial response, or partial response (PR) noted as the objective status on 2 separate evaluations while receiving ixazomib citrate with or without dexamethasone. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. 95% confidence intervals for the true success proportion will be calculated by the exact binomial method.

Secondary Outcome Measures

Confirmed response rate with the addition of dexamethasone (Arm A only) [Up to 2.5 years]
Estimated by the number of patients who achieve a confirmed response at any time (with single agent ixazomib citrate or ixazomib citrate plus dexamethasone) divided by the number of evaluable patients. 95% confidence intervals for the true confirmed response rate will be calculated by the exact binomial method.
Overall survival [From registration to death due to any cause, assessed up to 2.5 years]
The distribution of survival time will be estimated using the method of Kaplan-Meier.
Event-free survival [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]
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.
Incidence of adverse events [Up to 30 days after the last day of study drug treatment]
Graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. The maximum grade for each type of adverse event, regardless of causality, will be recorded and reported for each patient, and frequency tables will be reviewed to determine adverse event patterns.
