About this study

Official title: Phase I/II Study of Bendamustine and IXAZOMIB (MLN9708) Plus Dexamethasone in Relapsed/Refractory Multiple Myeloma

This Phase I/II study is designed to first identify doses of MLN9708 and bendamustine that are associated with an acceptable adverse event profile when delivered together in 28-day cycles. Additionally, the study aims to assess the efficacy of the combination in patients with relapsed/refractory multiple myeloma. Responders (stable disease or more), will continue to receive up to eight cycles total in the absence of further progressive disease.

Read the detailed description

OVERVIEW: This Phase I/II study is designed to first identify doses of MLN9708 and bendamustine that are associated with an acceptable adverse event profile when delivered together in 28-day cycles. Additionally, the study aims to assess the efficacy of the combination in patients with relapsed/refractory multiple myeloma. Responders (stable disease or more),will continue to receive up to eight cycles total in the absence of further progressive disease.

OVERVIEW OF THE DOSE ESCALATION/DE-ESCALATION: This study aims to assess the combination's efficacy in patients with relapsed/refractory multiple myeloma. Responders (stable disease or more) will continue to receive up to eight cycles total in the absence of further progressive disease. The dose of MLN9708 will be fixed at 4 mg given on days 1, 8 and 15. Dexamethasone will be administered at 40 mg (oral) on Days 1, 8, 15 of each 28 day cycle. Dexamethasone administered as 40 mg oral on Days 1, 8, 15 of each 28 day cycle. Three doses of bendamustine will be evaluated (Dose 1: 70 mg/m^2, days 1 and 2; Dose 2: 80 mg/m^2. days 1 and 2; and Dose 3: 90 mg/m^2, days 1 and 2).

PHASE 1 DESIGN: A 3+3 design was employed. At each dose, three patients were initially evaluated. When no dose limiting toxicities were observed, the bendamustine dose will be increased.

PHASE 2 DESIGN: Design for Phase II portion of study: The MTD or a recommended phase 2 dose (RP2D) for the combination. The plan is to treat additional patients at that dose to assess efficacy and response to treatment. The investigators plan to enroll 19 patients (including those treated at the MTD in Phase I).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum Tolerated Dose of Bendamustine

    Maximum tolerated dose of bendamustine in combination with fixed doses of ixazomib (MLN9708) and dexamethasone will be determined from the incidence of dose limiting toxicities at each dosage.

    Measured: Six months for each dosing cohort

  2. Objective Response Rate

    Objective response rate was defined as the number of subjects achieving a complete response (CR) or partial response (PR) after at least four cycles of ixazomib (MLN9708) and bendamustine plus dexamethasone.

    Measured: 18 months

Secondary outcomes (5)
  1. Overall Survival (OS)

    Overall survival was determined as the average number of months subjects survived following enrollment.

    Measured: 36 months

  2. Progression Free Survival (PFS)

    This measure is the number of months participants remain free from evidence of disease.

    Measured: 18 months

  3. Cumulative Response Rates in Patients After Eight Cycles.

    Percentage of subject response rates at any point during the eight cycles.

    Measured: 18 months

  4. Duration of Response (DoR)

    Median time in months participants maintain CR, PR or stable disease.

    Measured: 36 months

  5. Number of Participants Experiencing Dose-Limiting Toxicity (DLT)

    A 3+3 design was employed. At each dose, three patients were initially evaluated. If no dose limiting toxicities were observed, the bendamustine dose was increased; if one dose limiting toxicity is observed, three additional patients were treated at that dose. A dose at which 2 DLTs were observed in 3 or 6 patients were judged to be too toxic and the lower dose was defined as the maximally tolerated dose (MTD).

    Measured: Six months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing MLN9708, Dexamethasone and Bendamustine (multiple dose levels) in people with Multiple Myeloma, run by Parameswaran Hari at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Tolerated Dose of Bendamustine (time frame: Six months for each dosing cohort). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2020.
