Naive T Cell Deplete Grafts for GVHD Prevention in Non-Malignant Diseases
A Phase II Prospective Study Evaluating Selective Depletion of CD45RA+ (Naïve) T Cells (TND) From Peripheral Blood Stem Cell (PBSC) Grafts for Prevention of Graft Versus Host Disease (GVHD) in Non-Malignant Diseases (NMDs)
연구 개요
상태
상세 설명
OUTLINE: Patients will receive CD34+ enriched CD45RA-depleted donor T-lymphocytes IV on day 0. For conditioning, patients receive cyclophosphamide by IV on day -8, fludarabine by IV on day -7 to day -3, thiotepa IV on day -7 and day -6, and undergo total-body irradiation (TBI) for 2 doses on day -2 and day -1.
GVHD Prophylaxis:
All patients also receive tacrolimus IV continuously starting on day -1, and mycophenolate mofetil (MMF) starting day 0 through day 35. If there is no evidence of grade II-IV acute GVHD on or prior to day 100, tacrolimus is tapered.
All patients also undergo bone marrow aspiration/biopsy and collection of blood samples throughout the trial.
After completion of study treatment, patients are followed up at days 7, 14, 21, 28, 56, 80, 180, and 270 and at 1, 1.5, and 2 years.

Graft failure
기간: Day 42 post-transplant
|
Graft failure defined as failure to achieve an ANC ≥ 0.5 × 109/L before death or second HCT, or decrease to ANC <0.1 × 109/L for 14 consecutive days (date of graft failure defined as the 14th day) after an established donor graft despite daily administration of G-CSF (SC or IV) and ≤ average 20% bone marrow cellularity on bone marrow aspirate or biopsy any time in the first 2 years following HCT.
If a patient dies from organ toxicity and/or infection prior to day 28 without ANC ≥ 0.5 × 109/L this will not be considered graft failure.
If the graft failure is attributed to viral infection, multi-organ failure or drug effect it will still be considered graft failure if it meets the definition of graft failure specified above.
