Study Details

Study Description

Brief Summary

This is a Phase I/II study using the combination of twice weekly ixazomib plus pomalidomide and dexamethasone in relapsed and or refractory multiple myeloma (RRMM) patients.

Detailed Description

This is a Phase I/II clinical trial. A Phase I clinical trial tests the safety of an investigational drug and tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied.

The FDA has approved both pomalidomide and ixazomib individually for the treatment of multiple myeloma. Dexamethasone, also FDA approved, is a type of steroid and is usually combined with other chemotherapy for the treatment of blood cancers, such as myeloma and leukemias.

  • Ixazomib targets a part of cells called proteasomes. It works by slowing down or blocking proteasomes from doing their job of digesting proteins. In myeloma cells, there is a greater need for proteasomes to digest proteins; the buildup of excess proteins causes cell death.

  • Pomalidomide has also been shown to cause tumor cell deaths. Dexamethasone can stop white blood cells from traveling to areas myeloma cells are causing damage. When combined with myeloma drugs, it sometimes makes those drugs work better.

In this research study, the investigators are:
  • Testing the safety of ixazomib when given with pomalidomide and dexamethasone

  • Pomalidomide and ixazomib are given individually for the treatment of multiple myeloma. Dexamethasone is also given for multiple myeloma

  • Ixazomib when combined with pomalidomide and dexamethasone may help control the disease

  • Ixazomib is FDA approved to treat multiple myeloma

  • The investigators are looking for the highest dose of ixazomib that can be given safely in combination with pomalidomide and dexamethasone

Arms and Interventions

ArmIntervention/Treatment
Experimental: ixazomib plus pomalidomide and dexamethasone

The study drugs will be administered within a 21-day cycle Phase I will follow a standard "3 +3" dose escalation design: Starting with the first cohort, 3 to 6 patients will be treated at this and each subsequent dose level. The Phase II portion of the study will be a single-arm open-label enrollment with dosing based on the MTD determination in the Phase I portion of the study

    1. Number of participants with dose limiting toxicity [21 Days]

      3 - 24 safety evaluable patients will be enrolled in up to 4 dose levels of ixazomib, pomalidomide and dexamethasone.

    2. Overall Response Rate [28 days]

      Response will be evaluated using a Simon optimal two-stage design

    Secondary Outcome Measures

    1. Time to Progression [time from first dose of study drug to progression, censored at date last known progression-free for those who have not progressed, whichever came first, assessed up to 60 months]

      Estimated using the method of Kaplan-Meier.

    2. Progression Free Survival [time from first dose of study drug to the disease progression or death from any cause, censored at date last known progression-free for those who have not progressed or died, whichever came first, assessed up to 60 months]

      Estimated using the method of Kaplan-Meier.

    3. Duration of Response [time from response to disease progression or death, or date last known progression-free and alive for those who have not progressed or died, whichever came first, assessed up to 60 months]

      Estimated using the method of Kaplan-Meier.

    4. Overall Survival [time from first dose of study drug to death or date last known alive, whichever came first, assessed up to 60 months]

      Estimated using the method of Kaplan-Meier.
