Idasanutlin, Ixazomib Citrate, and Dexamethasone in Treating Patients With Relapsed Multiple Myeloma

• Status: Active, not recruiting
• Trial end date: 2022-08-15
• Target enrollment: 0
• Participant gender: All

Summary

This phase I/II trial studies the side effects and best dose of idasanutlin and ixazomib citrate when given together with dexamethasone in treating patients with multiple myeloma that has returned after a period of improvement. Drugs used in chemotherapy, such as idasanutlin and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving idasanutlin, ixazomib citrate, and dexamethasone together may work better in treating patients with multiple myeloma.

Exclusion Criteria:

• Other co-morbidity which would interfere with patient's ability to participate in trial, e.g. uncontrolled infection, uncompensated heart or lung disease

• Other concurrent chemotherapy, radiotherapy, or any ancillary therapy considered investigational

• NOTE: bisphosphonates are considered to be supportive care rather than therapy, and are thus allowed while on protocol treatment
