简要总结
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.
详细描述
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.

入选标准
- •AML patients in first complete remission (CR) (CR1) or first complete remission with incomplete blood count recovery (CRi) after induction and/or consolidation chemotherapy; except young (< 60 years) AML patients in European LeukemiaNet favorable group; (Since young AML patients in the European LeukemiaNet favorable group have excellent 2 year progression free survival [PFS] at around 64%, further maintenance therapy might not provide additional benefit; thus the current trial will exclude young favorable group AML patients), patients could receive any cycle consolidation or no consolidation per the discretion by the treating physician
- •Within 60 days after bone marrow biopsy confirmed remission after the patients recover from their last course of chemotherapy, the goal to consent the eligible patient prior to the remission confirmation bone marrow biopsy at the end of the planned chemotherapy); ideally, the research samples will be collected during the bone marrow biopsy, and the patient will be enrolled to the study within 2 weeks of the bone marrow biopsy; if there is delay to enroll the patient after the bone marrow biopsy and research sample collection, it is ok not to repeat bone marrow biopsy within 4 weeks, after the last bone marrow biopsy, if there is no sign of disease relapse; a repeat bone marrow biopsy should be done if the delay of enrollment is more than 4 weeks after the last bone marrow biopsy; patients with confirmed remission within 60 days after the last bone marrow biopsy, without research samples collection, should have a repeat bone marrow biopsy conducted within two weeks prior to enrolling on the study
- •Patient is not a candidate for stem cell transplant due to advanced age or co-morbidities; or the enrollee does not have donor available; or the enrollee declines stem cell transplant due to personal belief; or stem cell transplant is not standard of care based on the risk category of disease
- •Age >= 18 years. Because no dosing or adverse event data are currently available on the use of nivolumab in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials
- •Eastern Cooperative Oncology Group (ECOG)/Karnofsky performance status of 0 or 1 (Karnofsky >= 70%)
- •Life expectancy of greater than 6 months
- •Leukocytes >= 1,500/mcL

- •Serum creatinine =< 1.5 x ULN OR creatinine clearance (CrCl) >= 50 mL/min (if using the Cockcroft-Gault formula)
- •The effects of nivolumab on the developing human fetus are unknown; for this reason, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; WOCBP should use an adequate method to avoid pregnancy for 23 weeks after the last dose of investigational drug nivolumab; women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the start of nivolumab; women must not be breastfeeding; men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year; men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 31 weeks after the last dose of investigational product; women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception
- •Women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal; menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes; in addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level less than 40 mIU/mL
- •WOCBP receiving nivolumab will be instructed to adhere to contraception for a period of 23 weeks after the last dose of investigational product; men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 31 weeks after the last dose of investigational product; these durations have been calculated using the upper limit of the half-life for nivolumab (25 days) and are based on the protocol requirement that WOCBP use contraception for 5 half-lives plus 30 days and men who are sexually active with WOCBP use contraception for 5 half-lives plus 90 days
- •Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she (or the participating partner) should inform the treating physician immediately
- •Ability to understand and the willingness to sign a written informed consent document
排除标准
- •Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events (AEs) due to agents administered more than 4 weeks earlier
- •Patients who are receiving any other investigational agents
- •Patients should be excluded if they have had prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways
- •Patients with known central nervous system (CNS) involvement may be excluded because of poor prognosis and concerns regarding progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; however, if CNS disease is cleared before the treatment with nivolumab, patients could be allowed if no permanent CNS damage
