BMT Autologous MSCs for GvHD

EPIC MSC2014-002 solution- Autologous Mesenchymal Stromal Cells expanded using pooled human platelet lysate,is made up of autologous marrow-derived mesenchymal stromal cells ex vivo expanded numerically for approximately 14 days using pooled human Platelet Lysate (phPL), harvested from culture on the day of infusion and suspended at a concentration of 4 million cells/ml in Plasmalyte A with 0.5% human serum albumin. This is a phase I dose-escalation, open label, non-randomized, non-placebo controlled, single group assignment study to evaluate the safety and tolerability of EPIC MSC2014-002. The product will be infused intravenously and will be administered at one of three dose levels: (Dose level 1): Single Cell infusion 2 x 10\^6 cells/kg, (Dose Level 2): Two weekly Cell infusions 2 x 10\^6 cells/kg , (Dose level 3): Four weekly Cell infusion 2 x 10\^6 cells/kg. This Phase I clinical trial will enroll 12-24 subjects with acute or chronic GVHD. The duration of this study for each patient is 1 year. The investigators anticipate that this study will be completed within 3 years of commencement. Objectives: * To determine the safety and tolerability of infusing escalating doses of autologous MSCs for patients with acute or chronic GVHD. * To assess the overall response rate of acute and chronic GVHD to autologous MSC infusion. These data will be used to plan future, larger clinical trials to evaluate the efficacy of autologous MSCs for the treatment of GVHD. * To determine the effect of MSC infusion on lymphocyte phenotype, inflammatory biomarkers and GVHD specific biomarker levels
