Phase 2
Active, not recruiting
Conditions
Multiple Myeloma
Interventions
Registration Number
NCT02253316
Lead Sponsor
Washington University School of Medicine
Brief Summary

The purpose of this research study is to evaluate a treatment regimen called IRD which will be given to participants after their stem cell transplant in an effort to help prolong the amount of time the participants are disease-free after transplant. IRD is a three-drug regimen consisting of ixazomib, lenalidomide (also called Revlimid), and dexamethasone. After 4 cycles of IRD, the participants will be randomized to receive maintenance therapy either with ixazomib or lenalidomide.

Detailed Description

Based on the further need to improve progression-free survival and overall survival post-autologous stem cell transplantation (ASCT) for multiple myeloma and the benefits seen of consolidation/maintenance treatment with immunomodulatory drugs thalidomide and lenalidomide and the proteasome inhibitor bortezomib, the natural next step is to evaluate combination regimens of immunomodulatory drugs and proteasome inhibitors as consolidation/maintenance post-ASCT. The regimen consisting of ixazomib, lenalidomide, and dexamethasone (IRD) has been shown to have low toxicity, and the availability of an oral formulation of ixazomib allows for easier administration when compared to bortezomib.

In this study, following consolidation with IRD, patients will be randomized to maintenance therapy with lenalidomide or ixazomib in order to collect pilot data comparing the toxicity and efficacy of maintenance therapy with immunomodulatory drugs and proteasome inhibitors.

09/23/2019: Upon review of the interim analysis, there will be no further randomizations into the maintenance portion of the trial. All patients will be enrolled into the lenalidomide arm with the exception of those who discontinue lenalidomide during the consolidation phase due to toxicity. Patients who discontinue lenalidomide may be enrolled into the ixazomib arm following approval from the principal investigator.

09/30/2021: Following analysis 4 in 2021, analysis of the primary endpoint, all patients receiving lenalidomide maintenance will be transitioned off-study. Patients receiving ixazomib may remain on trial until disease progression or unacceptable toxicity at the discretion of the treating physician and the site principal investigator.

Consolidation: Ixazomib, Lenalidomide, & DexamethasoneIxazomibConsolidation therapy will begin between Day 80 and Day 120 following ASCT and will consist of four 28-day cycles of IRD (ixazomib, lenalidomide, \& dexamethasone). Barring dose modifications for toxicity, 4 mg of ixazomib and 40 mg of dexamethasone will be administered on Days 1, 8, and 15, and 15 mg of lenalidomide will be administered on daily on Days 1-21.
Maintenance Arm 1: IxazomibIxazomibIxazomib will be administered on Days 1, 8, and 15 of a 28-day cycle at a starting dose of 4 mg until patient progresses or experiences an unacceptable toxicity.

Maintenance Arm 2: LenalidomideLenalidomideLenalidomide will be administered daily continuously for a 28-day cycle at a starting dose of 10 mg. If lenalidomide is tolerated well (i.e. no dose modification required) during the first three cycles, lenalidomide dose will be increased to 15 mg daily and will continue until patient progresses or experiences an unacceptable toxicity.
Primary Outcome Measures
NameTimeMethod
Number of Participants With Improvement in Minimal Residual Disease (MRD)After 4 cycles of IRD consolidation treatment (approximately Day 112 of consolidation treatment)

For the purposes of this study, a patient will be considered as having minimal residual disease if a positive result (1x10E06) is obtained using the Adaptive Clonoseq MRD testing.

Secondary Outcome Measures
NameTimeMethod
Compare Toxicity Between the Two Maintenance Arms30 days after the completion of maintenance treatment (estimated to be Day 1125 of maintenance treatment)

The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.

Compare Response Rate Between the Two Maintenance ArmsThrough completion of maintenance treatment (estimated to be day 1095 of maintenance treatment)

* Response will be determined by the International Myeloma Working Group (IMWG) Uniform Response Criteria. Response includes stringent complete response (sCR) and complete response (CR).

* sCR requires all of the following:

* CR as defined below

* Normal free light chain ratio (0.26-1.65)

* Absence of clonal cells in the bone marrow by immunohistochemistry or immunofluorescence

* CR requires all of the following:

* Disappearance of monoclonal protein by both protein electrophoresis and immunofixation studies from the blood and urine

* If serum and urine monoclonal protein are unmeasurable, Normal free light chain ratio (0.26-1.65)

* \<5% plasma cells in the bone marrow

* Disappearance of soft tissue plasmacytoma
