Purpose

This research study is evaluating a new drug called "ixazomib" as a possible treatment for Smoldering Multiple Myeloma.

Detailed Description

      This research study is a Phase II clinical trial, which tests the effectiveness of an
      investigational drug(s). The investigational drugs used in this research study are Ixazomib,
      Lenalidomide and Dexamethasone.

      "Investigational" means that the FDA (the U.S. Food and Drug Administration) has not approved
      the combination of Ixazomib, Lenalidomide and Dexamethasone as a treatment regimen for
      Smoldering Multiple Myeloma. The purpose of this research study is to learn whether the
      combination of Ixazomib, Lenalidomide, and Dexamethasone works in treating Smoldering
      Multiple Myeloma.

      Ixazomib is a drug that may kill or stop cancer cells from growing by blocking the proteasome
      within the cell, which is responsible for degrading or breaking down a variety of proteins.
      This type of drug is called a proteasome inhibitor. Lenalidomide is an immunomodulatory drug,
      meaning it modifies the participant immune system to help fight the participant disease.
      Dexamethasone is a steroid, which is usually combined with other drugs to enhance their
      effects to fight the participant disease.

      Ixazomib is approved by the FDA in combination with Lenalidomide and Dexamethasone for the
      treatment of Multiple Myeloma and is currently being evaluated for use in the treatment of
      several types of cancers. Both Lenalidomide and Dexamethasone have been previously approved
      by the FDA for the treatment of Multiple Myeloma, as well as several other cancers.

Primary Outcome Measures

Measure:Proportion Of High Risk SMM Patients Who Are Progression Free 2 Years After Receiving IRD Combination Therapy
Time Frame:2 years
Safety Issue:
Description:The proportion of patients who achieve progression free at 2 years will be compared to the rate published for the high risk SMM. By the Mayo Clinic model for risk factors, the median time to progression for patients with high risk SMM was only 1.9 years. Therefore, we assume that, a 2-years progression-free rate of 50% will not be considered promising and a true progression free rate of 75% or higher will be considered promising.

Secondary Outcome Measures

Measure:Progression Free Survival
Time Frame:Time from protocol therapy initiation to the disease progression or death from any cause, censored at date last known progression free for those who have not progressed or died, or up to 60 months post initiation of therapy
Safety Issue:
Description:Progression-free survival is defined as the time from protocol therapy initiation to the disease progression or death from any cause, censored at date last known progression free for those who have not progressed or died
Measure:Time To Progression
Time Frame:The time from protocol therapy initiation until documented progression, censored at date last known progression-free for those who have not progressed or up to 60 months post initiation of therapy
Safety Issue:
Description:Time to progression (TTP) is defined as the time from protocol therapy initiation until documented progression, censored at date last known progression-free for those who have not progressed.
Measure:Duration of Response
Time Frame:time from objective response to disease progression or death, or date last known progression-free and alive for those who have not progressed or died, or up to 60 months post initiation of therapy
Safety Issue:
Description:Duration of response is defined as the time from objective response to disease progression or death, or date last known progression-free and alive for those who have not progressed or died
Measure:Objective Response Rate
Time Frame:2 years
Safety Issue:
Description:The objective response rate is defined as partial response or better according to the modified IMWG criteria and the proportion of patients with a MRD, CR, PR or MR will be reported with 90% exact binominal confidence interval (CI)
Measure:Overall Survival
Time Frame:Time from protocol therapy initiation to death or date last known alive, or up to 60 months post initiation of treatment
Safety Issue:
Description:Overall survival is defined as the time from protocol therapy initiation to death or date last known alive
