What's the purpose of this trial?

The main purpose of this study is to find out whether inobrodib, when given with pomalidomide and dexamethasone, works better than standard treatment for people whose multiple myeloma has come back or has not improved after previous treatment. 

This trial is currently open and accepting patients.

What will happen during the trial?

The study will look at how long people taking part in the study ("Participants") live without their myeloma getting worse, and how many people's myeloma improves (responds) following treatment. The study will also look at how long participants live overall, how quickly treatment works, how long the response lasts, whether very small amounts of myeloma can still be found after a good response, quality of life, side effects, and the amount of inobrodib in the blood. Participants receive treatment in 28-day cycles. One group receives inobrodib by mouth twice a day for 4 days, followed by 3 days without inobrodib each week; pomalidomide by mouth once a day on Days 1 to 21 of each cycle; and dexamethasone once each week. The other group receives 1 standard treatment chosen by the study doctor from the following treatment options: daratumumab, pomalidomide, and dexamethasone; elotuzumab, pomalidomide, and dexamethasone; or carfilzomib and dexamethasone. Some standard treatments are given by injection or infusion at the study site. Other medicines, such as tablets or capsules, may be taken by mouth as instructed by the study team. Study checks include questions about symptoms and side effects, review of other medicines, physical checks, blood pressure and other vital sign checks, heart tracing tests, blood and urine tests, scans where needed, bone marrow samples, and questionnaires about symptoms and daily life. Participants in the inobrodib group will have extra blood samples to measure the amount of inobrodib in the blood. Some participants may also have extra research blood samples at selected visits.

This is a Phase 3, multicenter, open-label, randomized study to evaluate inobrodib in combination with pomalidomide and dexamethasone (InoPd) versus standard available therapy (SAT), defined as Investigator's choice of daratumumab or elotuzumab in combination with pomalidomide and dexamethasone (DPd and EPd, respectively) or carfilzomib in combination with dexamethasone (Kd), in participants with relapsed or refractory multiple myeloma (RRMM).

Participants must be 18 years or older and have received 1 to 4 prior lines of therapy only.

Approximately 450 participants will be randomized 1:1 to be treated with either InoPd (Arm A) or Investigator's choice of SAT (Arm B), which includes DPd, EPd and Kd.

Study treatment should be continued until disease progression, initiation of new anticancer therapy, unacceptable toxicity or the participant meets any criteria for withdrawal from the study.

The dual primary objectives are to compare the efficacy of InoPd with Investigator's choice of SAT in terms of progression-free survival (PFS) and objective response rate (ORR) by Blinded Independent Central Review (BICR) in participants receiving InoPd versus participants receiving SAT.

The study will use a Steering Committee, consisting of selected participating Principal Investigators, Contract Research Organization (CRO) and Sponsor representatives, and an Independent Data Monitoring Committee (IDMC), for the purposes of conduct and oversight of the study.
