Spots Global Cancer Trial Database for Testing the Addition of Ixazomib/Placebo to Lenalidomide in Patients With Evidence of Residual Multiple Myeloma, OPTIMUM Trial

Study Description

Brief Summary: This phase III trial studies how well lenalidomide in combination with ixazomib works compared to lenalidomide alone in treating patients with evidence of residual multiple myeloma after stem cell transplantation. Lenalidomide may help shrink or slow the growth of multiple myeloma. Ixazomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving lenalidomide and ixazomib together may work better than giving lenalidomide alone in treating patients with evidence of residual multiple myeloma after a stem cell transplantation.

Detailed Description: PRIMARY OBJECTIVE: I. To evaluate whether escalating maintenance therapy with the addition of ixazomib citrate (ixazomib) to lenalidomide improves overall survival (OS) among patients who are minimal residual disease (MRD) positive after approximately 1 year of lenalidomide maintenance following an early stem cell transplant (=\< 12 months from diagnosis). SECONDARY OBJECTIVES: I. To establish whether progression-free survival (PFS) is superior with the addition of ixazomib to lenalidomide maintenance. II. To evaluate best response on treatment and compare response rates between arms. III. To evaluate the safety profile of ixazomib added to lenalidomide and compare toxicity rates between arms. EXPLORATORY OBJECTIVES: I. To measure treatment exposure and adherence. II. To estimate treatment duration, duration of response and time to progression. PATIENT-REPORTED OUTCOMES (PRO) OBJECTIVES: I. To quantify the extent to which the addition of ixazomib to lenalidomide maintenance contributes to neuropathy and associated physical and functional impairments. (Primary) II. To assess the impact of the addition of ixazomib to lenalidomide maintenance on disease control and associated physical and functional well-being. (Primary) III. To evaluate time to worsening and recovery rate related to neuropathy. (Secondary) IV. To evaluate time to improvement and response rate related to disease control. (Secondary) V. To evaluate attributes of select patient reported treatment-emergent symptomatic adverse events (Patient-Reported Outcomes - Common Terminology Criteria for Adverse Events \[PRO-CTCAE\]) longitudinally and compare responses with provider-reported adverse events. (Exploratory) VI. To measure the likelihood of medication adherence and examine the relationship with treatment exposure. (Exploratory) VII. To assess correlation among patient reported outcome measures and association with clinical outcomes. (Exploratory) VIII. To tabulate PRO compliance and completion rates. (Exploratory) IMAGING OBJECTIVES: I. To evaluate the association between baseline fludeoxyglucose F-18 (18F-FDG)-positron emission tomography (PET)/computed tomography (CT) and patient outcomes. II. To compare overall survival (OS) with the addition of ixazomib to lenalidomide among baseline 18F-FDG PET/CT-positive and 18F-FDG PET/CT -negative subgroups. III. To compare the change in quantitative 18F-FDG PET/CT parameters over time with the addition of ixazomib to lenalidomide. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-28 and ixazomib citrate PO on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspirate and/or biopsy and positron emission tomography (PET) and computed tomography (CT) scan at screening and on study as well as undergo collection of blood samples throughout the trial. ARM B: Patients receive lenalidomide PO QD on days 1-28 and a placebo PO on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspirate and/or biopsy and PET and CT scan at screening and on study as well as undergo collection of blood samples throughout the trial. After completion of study treatment, patients are followed up every 3 months if \< 2 years from study entry, every 6 months if 2-5 years from study entry, then every 12 months for up to 10 years from study entry.
