简要总结
This pilot phase II trial studies how well high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil work in preventing graft versus host disease in patients with hematological malignancies undergoing myeloablative or reduced intensity donor stem cell transplant. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil after the transplant may stop this from happening.
详细描述
PRIMARY OBJECTIVES:
I. To estimate the graft versus host disease (GVHD)-free relapse/progression-free survival (GRFS) at one-year post hematopoietic cell transplantation (HCT) and to evaluate the clinical activity of post-transplant high dose cyclophosphamide (PTCy).
SECONDARY OBJECTIVES:
I. To summarize toxicities/complications/infections including type, frequency, severity, attribution, time course and duration through 100 days post-transplant.
II. To estimate the cumulative incidence (CI) of acute and chronic GVHD. III. To characterize the time course of neutrophil and platelet recovery/engraftment.

结局指标
主要结局
Graft-Versus-Host Disease-Free, Relapse-Free Survival (GRFS) at 1 Year
时间窗: From stem cell infusion to grade 3-4 acute graft versus host disease (GVHD), moderate-severe chronic GVHD, relapse, progression or death (from any cause), whichever occurs first, assessed for up to 1 year.
Estimates will be calculated using the Kaplan-Meier method, Greenwood formula will be used to calculate standard error (SE), and log-log transformation method will be used to construct 95% confidence intervals. Graft versus host disease (GVHD, acute and chronic), disease status and vital status will be monitored per clinical standard operating procedure. For this endpoint failure is defined as the first occurrence of grade 3 or 4 acute GVHD, or moderate/severe chronic GVHD, or disease relapse (for patients in complete remission at the start of conditioning) or disease progression (for patients with active disease at the start of conditioning) or death (from any cause). Patients not experiencing any of these will be censored at his/her date of last contact.
次要结局
- Overall Survival (OS) at 1 Year(From start of transplant to death, or last follow up, whichever occurs first, assessed for up to 1 year.)
- Acute Graft Versus Host Disease (aGVHD) of Grades 2-4 According to the Consensus Grading(Up to 100 days post-stem cell infusion)
