A Multicenter In-class Transition Study of Ixazomib Combined With Pomalidomide and Dexamethasone or With Lenalidomide and Dexamethasone in Adults With Relapsed/Refractory Multiple Myeloma — US MM-7  

Multiple Myeloma Clinical Trial

Official title: An Open-Label, Non-Comparative, Two-Cohort, Multicenter Study to Evaluate the Effectiveness and Safety of Ixazomib (NINLARO®) in Combination With Pomalidomide and Dexamethasone (IPd, Cohort A) or With Lenalidomide and Dexamethasone (IRd, Cohort B) in Patients With Relapsed/Refractory Multiple Myeloma Previously Receiving a Parenteral Proteasome Inhibitor-based Treatment Regimen (US MM-7)

Status Withdrawn

Clinical Trial Summary

The main aim is to show that long-term use of ixazomib can improve symptoms of multiple myeloma and provide an effective long-term alternative treatment.

Participants will take ixazomib orally (by mouth) with pomalidomide and dexamethasone or lenalidomide and dexamethasone in 28-day treatment cycles. Participants will be treated for a maximum of 39 cycles but may continue to receive ixazomib beyond 39 cycles if they are benefiting from it. A follow-up study visit will occur 30 days after the last dose of ixazomib. Participants will be monitored for up to 3 years.

Clinical Trial Description

The main objective is to determine whether an in-class transition (iCT) from a parenteral proteasome inhibitor (PI) regimen to an all-oral ixazomib(NINLARO) regimen can improve outcomes and provide an effective long-term alternative treatment for participants with relapsed and/or refractory multiple myeloma.

The drug being tested in this study is called ixazomib (NINLARO). Ixazomib is being tested to treat people who have relapsed and/or refractory multiple myeloma (R/R MM). This study will look at the efficacy and safety of ixazomib in participants with R/R MM who were previously receiving parenteral proteasome inhibitor (PI)-based therapy in combination with pomalidomide or with lenalidomide, and who undergo in-class transition to an oral ixazomib-based combination containing either pomalidomide (cohort A) or lenalidomide (cohort B).

The study will enroll approximately 140 patients. Participants will be enrolled to one of the two treatment groups, depending on whether they are transitioning from a pomalidomide- or lenalidomide- based regimen:

• Cohort A: Ixazomib 4 mg + Pomalidomide 4 mg + Dexamethasone 40 mg

• Cohort B: Ixazomib 4 mg + Lenalidomide 25 mg + Dexamethasone 40 mg

Participants who are >75 years of age at time of enrollment will be instructed to take 20 mg dexamethasone. For participants with moderate or severe hepatic impairment, severe renal impairment, or end-stage renal disease requiring dialysis, the recommended starting dose of ixazomib is 3 mg which can be further reduced to 2.3 mg at investigator's discretion.

This multi-center trial will be conducted at approximately 30 study centers across the United States. The overall duration of this study is approximately 5 years or until all participants have died, have been lost to follow-up, or completion of the study by the sponsor, whichever occurs first. ;
