Umbilical Cord Derived Mesenchymal Stromal Cells For The Treatment of Severe Steroid-resistant Graft Versus Host Disease (PTC-UC-MSC)
Hematologic Malignancies
About this trial
This is an interventional treatment trial for Hematologic Malignancies
Eligibility Criteria
Inclusion Criteria:
Patients are required to meet the following inclusion criteria:
- Patients with steroid refractory grade III-IV classic acute graft versus host disease (GvHD)occurring within 100 days after transplant or induced by donor lymphocyte infusions (DLI) or T-cell add back. Steroid refractory graft versus host disease (GvHD)is defined according to Pidala and Anasetti10 as follows: a) progression of at least 1 overall grade within 3 days of optimal steroid treatment; b) failure to demonstrate any overall grade improvement over 5 to 7 days; c) incomplete response by 14 days of 2 mg/kg/day of steroid therapy.
- Patients with persistent, recurrent, or late acute graft versus host disease (GvHD) (features of acute graft versus host disease occurring beyond 100 days, often during withdrawal of immune suppression).
- Patients with an overlap syndrome in which diagnostic or distinctive features of chronic graft versus host disease (GvHD) and acute graft versus host disease (GvHD) appear together79.
Exclusion Criteria:
1. Inability to obtain written informed consent

Arm 1
Experimental
Umbilical Cord Mesenchymal stromal cells (UC-MSC)
Pentostatin will be given by intravenous infusion at a dose of 1 mg/m2 for 3 consecutive days. Thereafter, three Umbilical Cord Mesenchymal stromal cells (UC-MSC) infusions will be given at weekly interval starting from day 5. We will follow a dose escalating programme with progressively increasing doses of cells until the maximally tolerated dose (MTD) is achieved. The dose escalating design will be characterised by the administration of 1x106 /kg UC-MSC per dose per three doses for the first three patients (total up to 3x106/kg). The second three patients will receive 2x106/kg UC-MSC per dose per three doses (total up to 6x106/kg). The third three patients will receive 3x106/kg UC-MSC per dose per three doses (total up to 9x106 cells/kg). Since three dosages of cells are programmed for each group of 3 patients, a minimum of 9 patients should be studied, unless unacceptable acute infusion related toxicity is observed.
