Clinical Trial Summary

The purpose of this research study is to evaluate a treatment regimen called IRD which will be given to participants after their stem cell transplant in an effort to help prolong the amount of time the participants are disease-free after transplant. IRD is a three-drug regimen consisting of ixazomib, lenalidomide (also called Revlimid), and dexamethasone. After 4 cycles of IRD, the participants will be randomized to receive maintenance therapy either with ixazomib or lenalidomide.

Description:

Based on the further need to improve progression-free survival and overall survival post-autologous stem cell transplantation (ASCT) for multiple myeloma and the benefits seen of consolidation/maintenance treatment with immunomodulatory drugs thalidomide and lenalidomide and the proteasome inhibitor bortezomib, the natural next step is to evaluate combination regimens of immunomodulatory drugs and proteasome inhibitors as consolidation/maintenance post-ASCT. The regimen consisting of ixazomib, lenalidomide, and dexamethasone (IRD) has been shown to have low toxicity, and the availability of an oral formulation of ixazomib allows for easier administration when compared to bortezomib. In this study, following consolidation with IRD, patients will be randomized to maintenance therapy with lenalidomide or ixazomib in order to collect pilot data comparing the toxicity and efficacy of maintenance therapy with immunomodulatory drugs and proteasome inhibitors. 09/23/2019: Upon review of the interim analysis, there will be no further randomizations into the maintenance portion of the trial. All patients will be enrolled into the lenalidomide arm with the exception of those who discontinue lenalidomide during the consolidation phase due to toxicity. Patients who discontinue lenalidomide may be enrolled into the ixazomib arm following approval from the principal investigator. 09/30/2021: Following analysis 4 in 2021, analysis of the primary endpoint, all patients receiving lenalidomide maintenance will be transitioned off-study. Patients receiving ixazomib may remain on trial until disease progression or unacceptable toxicity at the discretion of the treating physician and the site principal investigator.

• Women of childbearing potential must follow pregnancy testing requirements as outlined in the Revlimid REMS program material. This is defined as either committing to continued abstinence from heterosexual intercourse or beginning TWO acceptable methods of contraception (one highly effective method and one additional effective method AT THE SAME TIME) at least 28 days prior to the start of lenalidomide, for the duration of study participation, and for 28 days following the last dose of lenalidomide. Women of childbearing potential must also agree to ongoing pregnancy testing.
• Men must agree to use a latex condom during sexual contact with a woman of childbearing potential even if they have had a successful vasectomy.

Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
• All study participants must be registered into the mandatory Revlimind REMS program and be willing to comply with its requirements. Per standard Revlimid REMS program requirements, all physicians who prescribe lenalidomide for research subjects enrolled into this trial, must be registered in, and must comply with, all requirements of the Revlimid REMS program. Exclusion Criteria Patients meeting any of the following exclusion criteria are not to be enrolled in the

study:

• Female patients who are lactating or have a positive serum pregnancy test during the screening period
• Evidence of MM disease progression any time prior to enrollment. Progression from smoldering/asymptomatic MM to symptomatic MM is not exclusionary.
• Tandem autologous transplantation
• History of plasma cell leukemia or MM CNS involvement
• Administration or planned administration of any other concomitant chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy which would be considered a treatment of multiple myeloma until Day +28 post-transplant through discontinuation from study. Patients may be on corticosteroids if they are being given for disorders other than multiple myeloma (e.g., adrenal insufficiency, rheumatoid arthritis, etc.)
• Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
• Prior organ transplant requiring immunosuppressive therapy
• Active hepatitis A, B or C virus infection, or known human immunodeficiency virus (HIV) positive
• Known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent
• Known GI disease or GI procedure that could interfere with the oral absorption or tolerance of ixazomib
• Concurrent hematologic or non-hematologic malignancy requiring treatment (other than multiple myeloma and secondary amyloidosis)
• Cardiac syncope, uncompensated NYHA Class 3 or 4 congestive heart failure, myocardial infarction within the previous six months, unstable angina pectoris, clinically significant repetitive ventricular arrhythmias despite antiarrhythmic treatment, severe orthostatic hypotension, or clinically important autonomic disease
• Grade >= 3 peripheral neuropathy, or Grade 2 with pain on clinical examination during the screening period
• Major surgery within 14 days prior to enrollment
• Infection requiring systemic antibiotic therapy or other serious infection within 14 days prior to enrollment
• Participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days prior to enrollment and throughout the duration of this trial
