Spots Global Cancer Trial Database for Testing Nivolumab to Prevent Disease From Coming Back After Treatment in Patients With Acute Myeloid Leukemia, REMAIN Trial

Study Description

Brief Summary: This phase II trial studies how well nivolumab works in eliminating any remaining cancer cells and preventing cancer from returning in patients with acute myeloid leukemia that had a decrease in or disappearance of signs and symptoms of cancer after receiving chemotherapy. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Detailed Description: PRIMARY OBJECTIVE: I. To evaluate and compare the progression free survival rate after randomization in the two treatment arms (nivolumab versus \[vs.\] observation). SECONDARY OBJECTIVES: I. To determine and compare the overall survival rates in the two arms. II. To determine and compare the incidence of non-relapse mortality in the two arms. III. To evaluate the toxicities of nivolumab as maintenance. EXPLORATORY OBJECTIVES: I. To analyze PD-L1 expression on acute myeloid leukemia (AML) cells from peripheral blood and/or bone marrow samples at diagnosis if available and at the time of study enrollment. II. To monitor AML minimal residual disease (MRD) by Wilms tumor 1 (WT1) polymerase chain reaction (PCR) at enrollment and at subsequent defined time points in the nivolumab-treated and control groups. III. To perform an exploratory analysis on the frequencies, absolute numbers and subsets of T cells (including regulatory T cells) in the nivolumab-treated and control groups with an emphasis on activation markers. IV. To perform deep sequencing of T cell receptor (TCR)-alpha and TCR-beta chains on polyclonal T cells at baseline and at subsequent time points in the nivolumab and control groups. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive nivolumab intravenously (IV) over 30 minutes once every 2 weeks. Treatment repeats every 2 weeks for 46 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow biopsy at screening, months 3, 6, and 12, as clinically indicated, and at the time off study. Patients also undergo collection of blood samples at screening, weeks 9, 13, 25, and 53, and during off-study evaluation or at time of clinically suspected relapse. Patients may undergo echocardiography (ECHO) as clinically indicated. ARM II: Patients undergo standard of care clinical observation for up to 2 years. Upon disease relapse, patients may cross-over to Arm I. Patients also undergo bone marrow biopsy at screening, months 3, 6, and 12, as clinically indicated, and during off-study evaluation. Patients also undergo collection of blood samples at screening, weeks 9, 13, 25, and 53, and during off-study evaluation or at time of clinically suspected relapse. Patients may undergo ECHO as clinically indicated. After completion of study treatment, patients are followed up periodically for 2 years, every 6 months for 1 year, and then yearly thereafter.
