Brief Summary:
This phase I/II trial studies the side effects and best dose of ixazomib and to see how well it works when given together with pomalidomide and dexamethasone in treating patients with relapsed or relapsed/refractory multiple myeloma. Ixazomib may stop the growth of cancer by interfering with proteasomes (the protein breakdown mechanism in the cells). Pomalidomide and dexamethasone can modify and regulate the immune system and may stop cancer cells from growing. Giving ixazomib with pomalidomide and dexamethasone may be an effective treatment for relapsed or relapsed/refractory multiple myeloma.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the recommended phase II dose (RP2D) of MLN9708 (ixazomib), when given in combination with pomalidomide and dexamethasone, in patients with relapsed or relapsed/refractory multiple myeloma. (Phase I) II. To estimate the response rate and to evaluate the antitumor activity of the three drug combination: MLN9708 (at the RP2D), pomalidomide and dexamethasone, in patients with relapsed or relapsed/refractory multiple myeloma. (Phase II)

SECONDARY OBJECTIVES:

I. To evaluate the safety of MLN9708 at each dose level when given as part of a three drug combination by assessing the following: type, frequency, severity, attribution, time course and duration of adverse events; and clinical laboratory tests at various points in the study. (Phase I) II. To characterize and evaluate toxicities, including type, frequency, severity, attribution, time course and duration, at the RP2D, for the three drug combination. (Phase II) III. To obtain estimates of response duration, depth of response, clinical benefit response, and survival (overall and progression-free), at the RP2D, for the three drug combination. (Phase II)

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

Patients receive ixazomib orally (PO) on days 1, 8, and 15; dexamethasone PO on days 1, 8, 15, and 22; and pomalidomide PO on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years.

Primary Outcome Measures :
  1. Toxicity graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events version 4.03 (Phase I) [ Time Frame: Up to 28 days ]
    The highest dose level that produces 1/6 dose-limiting toxicities (DLTs) in course 1 will be the maximum tolerated dose (MTD). The RP2D of ixazomib and pomalidomide will generally be the MTD, but it may be less than the MTD based on a review of available data/cumulative toxicities from phase I.

  2. Response rate (confirmed stringent complete remission [sCR]/complete remission [CR]/very good partial remission [VGPR] or partial remission [PR]), based on the IMWG criteria (Phase II) [ Time Frame: Up to 24 months ]
    Response rates (overall, clinical benefit) and depth of response will be calculated as the percent of evaluable patients that have confirmed sCR/CR/VGPR or PR (overall) or sCR/CR/VGPR/PR/minimal response (MR) or stable disease (SD) (clinical benefit), exact 95% confidence intervals will be calculated for these estimates. Response rates will also be evaluated based on number and type of prior therapy(ies).


Secondary Outcome Measures :
  1. Duration of response (Phase II) [ Time Frame: Time interval from the date of first documented response (sCR/CR/VGPR or PR) to documented disease relapse, progression or death whichever occurs first, up to 24 months ]
    This will be estimated using the product-limit method of Kaplan and Meier.

  2. Clinical benefit response, based on the IMWG criteria, calculated as the number of responders plus those with a minimal response (MR) or stable disease (SD) divided by the number of evaluable patients (Phase II) [ Time Frame: Up to 24 months ]
  3. Overall survival (Phase II) [ Time Frame: Date of first dose of study drug to date of death from any cause, up to 24 months ]
    This will be estimated using the product-limit method of Kaplan and Meier.

  4. Progression-free survival (Phase II) [ Time Frame: Date of first dose of study drug to first documented disease relapse, progression or death from any cause, whichever occurs first, up to 24 months ]
    This will be estimated using the product-limit method of Kaplan and Meier.
