Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the safety and efficacy of autologous bone marrow stem cell implantation for the treatment of leg ulcer in adult patients with sickle cell disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Implantation of bone marrow mononuclear cells, including endothelial progenitor cells and mesenchymal stromal cells, into leg ulcers has been shown to improve wound healing.

In the present study the safety and efficacy of autologous bone marrow mononuclear cells implantation will be investigated in patients with chronic leg ulcers. Forty cases will be enrolled. Improvement in the pain, rate and extent of leg ulcer wound healing as measured by change in wound surface area will be evaluated until one year.

Stem Cell Injection

Intramuscular implantation of Autologous bone marrow-derived mononuclear cells

Group Type EXPERIMENTAL

Infusion of Autologous Bone Marrow Mononuclear Cells

Intervention Type BIOLOGICAL

Autologous bone marrow-derived mononuclear cells will be administered by intramuscular injection into and around the leg ulcer. The number of injected cells will be from 5x108 to 1x109 total number of cells on Study Day 1.
