Clinical Trial With MSC for Graft Versus Host Disease Treatment

Study Overview
=================
Brief Summary
-----------------
Sequential administration of MSCs obtained from adipose tissue is an effective and safe treatment for acute graft versus host disease refractory to first-line treatment. Furthermore the infusion of these cells produces a biological pattern in patients that relates to the clinical response.

Detailed Description
-----------------
Multicenter, open, non -controlled clinical trial. It is a phase I-II trial to assess the safety and efficacy of sequential infusion of allogeneic MSCs from adipose tissue, expanded in vitro platelet lysate in the treatment of patients undergoing hematopoietic stem cell trasplantation, who have developed a refractory graft versus host disease to first line of treatment. This is a prospective, multicenter, open to patients undergoing allogeneic transplantation in Spanish hospitals, with one cohort of patients who receive four sequential doses of MSC.

The source may have been bone marrow cells or peripheral blood (PB) and coming from a family member or unrelated donor. Having been transplanted with myeloablative or non-myeloablative conditioning. normal cardiac function (EF ≥ 40%) without evidence of uncontrolled hypertension, congestive heart failure, angina pectoris or myocardial infarction within 6 months prior to the process Lung function without evidence of severe obstructive or restrictive lung disease. Age between 18 and 65 years. Women of childbearing age considered until one year after the last menstrual period and which have not undergone a surgical sterilization must obtain a negative pregnancy test at the time of inclusion in the study and commit to use a medically approved birth control while on study. normal cardiac function (EF ≥ 40%) without evidence of uncontrolled hypertension, congestive heart failure, angina pectoris or myocardial infarction within 6 months prior to the process.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Allogeneic Mesenchymal Cells<br>All patients will receive Adult Allogeneic Mesenchymal Cell from adipose tissue. It is not considered ethical the inclusion of a control group. | Drug: Adult Allogeneic Mesenchymal cells from adipose tissue.<br>* Study treatment consists of Mesenchymal Stem Cell (MSC) derived from donors adipose tissue and expanded in vitro in a specific medium with platelet lysate without addition of animal derived products. Subjects will receive four sequential IV dose of Mesenchymal stem cells.
