This phase II trial studies how well proteasome inhibitor MLN9708 works in treating patients with relapsed multiple myeloma that is not refractory to bortezomib. Proteasome inhibitor MLN9708 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Primary Outcome Measures:
  • Proportion of confirmed response (stringent complete response [sCR], CR, very good partial response [VGPR], PR) with single agent proteasome inhibitor MLN9708 [ Time Frame: up to 4 months ] [ Designated as safety issue: No ]
    A confirmed response is defined as sCR, CR, VGPR, or PR noted as the objective status on 2 separate evaluations while receiving single agent proteasome inhibitor MLN9708. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients.

Secondary Outcome Measures:
  • Overall response rate of MLN9708 in combination with dexamethasone by bone marrow aspirate and biopsy, myeloma FISH, metaphase cytogenetics, PCLI, and flow cytometry at 2 and 4 months. [ Time Frame: no longer than 2 years ] [ Designated as safety issue: No ]
  • Survival out to 2 years [ Time Frame: Every 6 months for 2 years ] [ Designated as safety issue: No ]
  • Disease-free survival [ Time Frame: Every 6 months for 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 103
Study Start Date: January 2012
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (enzyme inhibitor, dexamethasone)
Patients receive MLN9708 PO on days 1, 8 and 15. Patients with lack of minor response by the end of the second course or lack of partial response by the end of the fourth course also receive dexamethasone PO on days 1, 2, 8, 9, 15, and 16. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Detailed Description:


I. To determine the confirmed overall response rate (>= partial response [PR]) of MLN9708 (proteasome inhibitor MLN9708), 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.


I. To determine the overall response rate of MLN9708 in combination with dexamethasone, when dexamethasone is added to MLN9708 for lack of response or for progression.

II. To determine the event free survival and overall survival among patients with relapsed myeloma following treatment with MLN9708 with dexamethasone added for lack of response or progression.


Patients receive MLN9708 orally (PO) on days 1, 8 and 15. Patients with lack of minor response by the end of the second course or lack of partial response by the end of the fourth course also receive dexamethasone PO on days 1, 2, 8, 9, 15, and 16. Courses 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.
