Multiple Myeloma Clinical Trial
Venetoclax, Ixazomib Citrate, and Dexamethasone in Treating Patients With Relapsed Multiple Myeloma
This phase I 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.
I. To determine the maximum tolerated dose (MTD) of venetoclax in combination with ixazomib citrate (ixazomib) and dexamethasone in patients with relapsed multiple myeloma (MM). (Phase 1)
I. To describe toxicities associated with venetoclax, in combination with ixazomib and dexamethasone in patients with relapsed MM. (Phase 1)
I. To explore levels of BCL-2 family member proteins (BCL-2, BCL-x, MCL-1) on bone marrow biopsies using ribonucleic acid sequencing (RNASeq) and immunohistochemistry.
OUTLINE: This is a phase I, dose-escalation study of venetoclax followed by a phase II study.
Patients receive venetoclax orally (PO) daily on days 1-28, ixazomib citrate PO once weekly on days 1, 8, and 15, and dexamethasone PO on days 1, 8, 15, and 22 for courses 1-12. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 or 6 months for 3 years.
Phase 1: Relapsed MM with at least one prior line of therapy and should have received a proteasome inhibitor and an immunomodulatory drug
Phase 2: 1-3 prior lines of therapy and should have received a proteasome inhibitor and an immunomodulatory drug

Provide written informed consent
Negative serum pregnancy test done =< 7 days prior to registration, for women of childbearing potential only
Willing to follow strict birth control measures as suggested by the study
Female patients: If they are of childbearing potential, must agree to one of the following:
Practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, AND must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, OR
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)
Male patients: even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following:
Agree to practice effective barrier contraception during the entire study treatment period and through 120 days after the last dose of study drug, OR
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)
Life expectancy >= 12 weeks
Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)
Willing to provide research bone marrow aspirate specimen
Diagnosed or treated for another malignancy =< 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease; NOTE: Patients with non-melanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection
Any of the following:
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
Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies) or active hepatitis
Administration of a strong or moderate CYP3A inhibitor or inducer =< 14 days prior to registration

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
