研究概览
简要总结
This phase II trial studies the effect of nivolumab in combination with blinatumomab compared to blinatumomab alone in treating patients with B-cell acute lymphoblastic leukemia (B-ALL) that has come back (relapsed). Down syndrome patients with relapsed B-ALL are included in this study. Blinatumomab is an antibody, which is a protein that identifies and targets specific molecules in the body. Blinatumomab searches for and attaches itself to the cancer cell. Once attached, an immune response occurs which may kill the cancer cell. Nivolumab is a medicine that may boost a patient's immune system. Giving nivolumab in combination with blinatumomab may cause the cancer to stop growing for a period of time, and for some patients, it may lessen the symptoms, such as pain, that are caused by the cancer.
详细描述
PRIMARY OBJECTIVES:
I. To compare event free survival post reinduction (EFS PR) between blinatumomab vs. blinatumomab/nivolumab in Group 4 patients aged ≥ 1 to <31 years old with first relapse of CD19+ B ALL.
II. To compare EFS PR (EFS post-reinduction) between consolidation with blinatumomab vs. blinatumomab/nivolumab in Group 3 patients aged >= 1 to < 31 years old with first relapse of CD19+ B ALL.
SECONDARY OBJECTIVES:
I. To evaluate the safety and tolerability of blinatumomab/nivolumab in patients aged >= 1 to < 31 years old with first relapse of CD19+ B ALL.

- •Female patients of childbearing potential are not eligible unless a negative pregnancy test result has been obtained within 7 days prior to enrollment. Patients who are sexually active and of reproductive potential are not eligible unless they agree to use an effective contraceptive method for the duration of this study. Men with female partners of childbearing potential should use effective contraception during the duration of their treatment. The effect of blinatumomab on fertility has not been evaluated. Blinatumomab is not recommended for pregnant women or women of childbearing potential (WOCBP) not using contraception. Females of reproductive potential must use effective contraception during treatment and for at least 48 hours after the last dose of blinatumomab. Studies in animal models have shown that nivolumab can adversely impair pregnancy. Thus, nivolumab is expected to cause fetal harm during pregnancy. WOCBP receiving nivolumab must continue contraception for a period of at least 5 months after the last dose of nivolumab. It is unknown whether nivolumab is present in breast milk, thus breastfeeding should be discontinued while a patient is receiving nivolumab
- •Lactating females are not eligible unless they agree to not breastfeed their infants. It is unknown whether blinatumomab or its metabolites are excreted in human breast milk. Women are not permitted to breastfeed while receiving blinatumomab and for the last 48 hours after the last blinatumomab dose. Due to the potential for serious adverse reactions in the breastfed infant, women are not permitted to breastfeed during treatment and for 5 months after the last nivolumab dose

结局指标
主要结局
Minimal residual disease (MRD) negative second remission (Rem-2) rate with blinatumomab vs with blinatumomab + nivolumab (Group 1)
时间窗: Up to 2 cycles of therapy (each cycle = 36 days)
MRD negative Rem-2 be defined as Rem-2 (i.e., achievement of MRD \< 1% blasts by flow cytometry and resolution of extramedullary disease (for CNS disease, requires CNS 1) ) and bone marrow with MRD \< 0.01% by flow cytometry. MRD negative Rem-2 rate between Arm A vs Arm B will be compared using a one-sided Z test of proportions with Type I error of 0.10. Interim analysis will be conducted to monitor for futility. The futility boundaries are based on testing the alternative hypothesis at the 0.067 level.
Event-free survival post-reinduction (EFS PR) (Group 3)
时间窗: From date of randomization to date of treatment failure, relapse, disease progression, second malignancy (SMN) or death due to any cause, assessed up to 10 years after completion of enrollment.
Comparison of EFS post reinduction between Arm E versus Arm F will be based on a one-sided two-sample logrank test with Type I error of 0.10, to be conducted 3 years after completion of enrollment of Group 3. Interim analysis will be conducted to monitor for futility. The futility monitoring will be based on testing the alternative hypothesis at the 0.067 level. This alpha level corresponds to that which would cause futility stopping if the one-sided two-sample logrank test shows evidence of a hazard ratio \> 1.0 when half of the expected events are observed.
EFS PR (Group 4)
时间窗: From date of randomization to date of treatment failure, relapse, disease progression, second malignancy (SMN) or death due to any cause, assessed up to 10 years after completion of enrollment.
Comparison of EFS post reinduction between Arm H versus Arm I will be based on a one-sided two-sample logrank test with Type I error of 0.10, to be conducted 3 years after completion of enrollment of Group 3. Interim analysis will be conducted to monitor for futility. The futility monitoring will be based on testing the alternative hypothesis at the 0.067 level. This alpha level corresponds to that which would cause futility stopping if the one-sided two-sample logrank test shows evidence of a hazard ratio \> 1.0 when half of the expected events are observed.
Event-free survival post-reinduction (EFS PR) (Group 3)
时间窗: From date of randomization to date of treatment failure, relapse, second malignancy (SMN) or death due to any cause, assessed up to 10 years after completion of enrollment.
Comparison of EFS post reinduction between Arm E versus Arm F will be based on a one-sided two-sample logrank test with Type I error of 0.15, to be conducted 3 years after completion of enrollment of Group 3. Interim analysis will be conducted to monitor for futility. The futility monitoring will be based on testing the alternative hypothesis at the 0.092 level. This alpha level corresponds to that which would cause futility stopping if the one-sided two-sample logrank test shows evidence of a hazard ratio \> 1.0 when half of the expected events are observed.
EFS PR (Group 4)
时间窗: From date of randomization to date of treatment failure, relapse, second malignancy (SMN) or death due to any cause, assessed up to 10 years after completion of enrollment.
Comparison of EFS post reinduction between Arm H versus Arm I will be based on a one-sided two-sample logrank test with Type I error of 0.10, to be conducted 3 years after completion of enrollment of Group 3. Interim analysis will be conducted to monitor for futility. The futility monitoring will be based on testing the alternative hypothesis at the 0.092 level. This alpha level corresponds to that which would cause futility stopping if the one-sided two-sample logrank test shows evidence of a hazard ratio \> 1.0 when half of the expected events are observed.
