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

• Status: Suspended
• Trial end date: 2022-03-02
• Target enrollment: 0
• Participant gender: All

Summary

This phase I/II trial studies the side effects and best dose of venetoclax when given together with ixazomib citrate and dexamethasone and to see how well they work in treating patients with multiple myeloma that has come back. Venetoclax and ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as 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. Giving venetoclax together with ixazomib citrate and dexamethasone may work better in treating patients with multiple myeloma.

• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

Exclusion Criteria:

• Any of the following:

• Pregnant women

• Nursing women

• Men or women of childbearing potential who are unwilling to employ adequate contraception

• 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 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

• Peripheral neuropathy >= grade 2 on clinical examination or grade 1 with pain during the screening period

• Major surgery =< 14 days prior to study registration

• History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject?s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator

• Failure to have fully recovered (i.e., =< grade 1 toxicity) from the reversible effects of prior chemotherapy

• Radiotherapy =< 14 days prior to registration; Note: If the involved field is small, 7 days will be considered a sufficient interval between treatment and administration of the ixazomib
