Idiopathic Pulmonary Arterial HypertensionNCT00372346
Safety and Efficacy Study of Transplantation of EPCs to Treat Idiopathic Pulmonary Arterial Hypertension
A study testing Transplantation of autologous endothelial progenitor cells in people with Idiopathic Pulmonary Arterial Hypertension, run by Zhejiang University at 1 site in China.
Trial summary
Experimental data suggest that transplantation of endothelial progenitor cells (EPCs) attenuates monocrotaline-induced pulmonary hypertension in rats and dogs. In addition, clinical studies suggest that autogolous progenitor cells transplantation is feasible and safe in patients with ischemic disease. Read more about this study

About this study
Experimental data suggest that transplantation of endothelial progenitor cells (EPCs) attenuates monocrotaline-induced pulmonary hypertension in rats and dogs. In addition, clinical studies suggest that autogolous progenitor cells transplantation is feasible and safe in patients with ischemic disease. This study will investigate the feasibility, safety, and initial clinical outcome of intravenous infusion of autologous EPCs in patients with idiopathic pulmonary arterial hypertension.
