Phase 2 Haplotype Mismatched HSCT in Patients With Hematological Malignancies

March 12, 2018 updated by: Sherif S. Farag

A Phase II Trial of Haplotype Mismatched Hematopoietic Stem Cell Transplantation Using Highly Purified CD34 Cells in Patients With Hematological Malignancies

The purpose of this study is to determine if haplotype-mismatched HSCT is associated with an improvement in treatment-related mortality (TRM) rate at 6 months.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment-related Mortality (TRM) Rate at 6 Months After Transplantation
Time Frame: thru 6 months after transplant
To determine if haplotype-mismatched HSCT is associated with a ≤40% treatment-related mortality (TRM) rate at 6 months after transplantation; a TRM ≥60% being considered unacceptable. The percent of patients with the exact 95% confidence interval who had treatment-related mortality within 6 months of their transplant is presented.
thru 6 months after transplant

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to Platelet Engraftment
Time Frame: Transplant (Day 0) up to 1 year
Time to platelet engraftment will be analyzed by the Kaplan-Meier method. The time to engraftment of platelets is defined as the time from day 0 to the first of seven consecutive days after transplantation during which the platelet count is at least 20 x109/l without transfusion support. Only patients who achieved engraftment of platelets will be included in the analysis. The median and 95% confidence intervals will be provided.
Transplant (Day 0) up to 1 year
Regimen-related Toxicity
Time Frame: Up to 1 year
The number of unique patients who had adverse events that were possibly/probably/definitely related to treatment/regimen.
Up to 1 year
Time to Neutrophil Engraftment
Time Frame: Transplant (Day 0) up to 1 year
Time to neutrophil engraftment will be analyzed by the Kaplan-Meier method. The time to engraftment of neutrophil is defined as the time from transplant until absolute neutrophil count (ANC) > 500 uL for 3 consecutive days. The median and 95% confidence intervals will be provided.
Transplant (Day 0) up to 1 year
Acute Graft vs. Host Disease (GvHD)
Time Frame: Up to 1 year
Number of unique patients who had acute Graft vs. Host Disease (GvHD) diagnosed while on the study.
Up to 1 year
Chronic Graft vs. Host Disease (GvHD)
Time Frame: Up to 1 year
Number of unique patients who had chronic Graft vs. Host Disease (GvHD) diagnosed while on the study.
Up to 1 year
Frequency of Infection
Time Frame: Day 0 through 1 year post transplantation
Number of unique patients with bacterial and/or viral infections reported.
Day 0 through 1 year post transplantation
