Brief Summary:

The purpose of this study is to investigate the efficacy and safety of autologous transplantation of Adipose Tissue derived Mesenchymal stem cells (MSCs) in patient with Buerger's disease.

Condition or disease	Intervention/treatment	Phase
Buerger's Disease	Biological: RNL-Vascostem®	Phase 1; Phase 2

Detailed Description:

Buerger's disease, also known as thromboangiitis obliterans, is a rare disorder that, in most cases, affects young or middle-aged male cigarette smokers. It is characterized by narrowing or blockage (occlusion) of the veins and arteries of the extremities, resulting in reduced blood flow to these areas (peripheral vascular disease). The exact cause of Buerger's disease is not known; however, most affected individuals are heavy tobacco users.

This drug is an autologous cell treatment for necrosis in the legs of patients with Beurger's diseases to improve symptoms through vascular regeneration.
