简要总结
Given the increased number of HLA-mismatched haploidentical transplantation with post-transplant cyclophosphamide performed each year and the high risk of infectious complications associated with this type of transplant, the investigators suggest that GM-CSF administration post-infusion of T-replete haploidentical stem cells and post-transplant cyclophosphamide can yield similar count recovery rates to G-CSF with a potential of lowering risk of infectious complications.

研究组 & 干预措施
GM-CSF post-transplant
Sargramostim (GM-CSF) will start on Day +5 and continue until ANC >1000 x3 days or >1500 x1 day. GM-CSF will be administered not less than 24 hours after the last dose of cyclophosphamide and will be given at a dose of 250mcg/m2/day as an infusion over 2 hours.
干预措施: Control Arm (Other)

结局指标
主要结局
The number of patients who achieved neutrophil engraftment at 20 days after the initiation of treatment.
时间窗: 3 months after initial treatment
The aim of the study is to establish equivalent effectiveness of Sargramostim to a matched control cohort of G-CSF treated patients in time to achieve neutrophil (ANC \>500 x3 days) post infusion of HLA-mismatched peripheral blood haploidentical stem cells with post-transplant cyclophosphamide. Patients will be followed for 3 months following the initiation of treatment to see engraftment numbers at 20 days after initial treatment.
次要结局
- How many patients have not relapsed measured by relapse rates at 12 months following the initiation of treatment.(12 months following initiation of treatment)
- Number of patients achieving platelet engraftment as measured by platelets reaching 20,000 without transfusion for 7 days(12 months following initiation of treatment)
- How many patients died due to infections measured by the incidence and type of infections at 12 months following initiation of treatment(12 months following initiation of treatment)
- How many patients died due to a treatment-related adverse events grade 2 or greater as assessed by CTCAE v.4.0(12 months following initiation of treatment)
- Number of patients to achieve full donor chimerisms at Days 30, 50, 100, and 6 months post-transplant as measured by donor chimerism data(12 months following initiation of treatment)
- Number of patients that acquired an infection in the first 100-days post-transplant as measured by the incidence of infections(12 months following initiation of treatment)
- How many patients are still alive measured by overall survival at 12 months following the initiation of treatment.(12 months following initiation of treatment)
- How many patients develop graft-versus-host-disease (GVHD) measured by the incidence of GVHD at 12 months following initiation of treatment(12 months following initiation of treatment)
- How many patients have not relapsed measured by progression-free survival at 12 months following the initiation of treatment(12 months following initiation of treatment)
