Study Summary

This study aims to evaluate safety, tolerance, and efficacy in subjects with over moderately subacute and chronic atopic dermatitis after an intravenous injection of autologous mesenchymal stem cells. The study is composed of two steps. Step 1 is to determine clinically proper dose capacity of the ADSTEM Inj. and step 2 is to evaluate exploratory efficacy of the ADSTEM Inj. at the proper dose.

Study Description

Atopic dermatitis (AD) is a type of inflammation of the skin. It results in itchy, swollen, red, and cracked skin. The symptoms typically start in childhood with changing severity over the years. The pathogenesis of AD is characterized by excessive type 2 helper T cell mediated inflammatory responses, resulting in B lymphocyte mediated increase in serum level of immunoglobulin E (IgE). Subsequent degranulation of mast cells by IgE releases various inflammatory mediators, which recruit the lymphocytes and eosinophils into the lesion.

Current clinical management of AD includes topical corticosteroids and systemic immunosuppressants. However, these drugs have been reported to carry the risk of side-effects and severe.

Several recent studies including ours have demonstrated that mesenchymal stem cells (MSCs) could suppress allergic responses in AD. MSCs have been known to interact with cell types of both innate and adaptive immune systems, which results in the suppressive effect on proliferation, differentiation, and activation of immune cells including T cells, B cells, dendritic cells, and natural killer cells. Indeed, a number of studies have reported that the immunomodulatory ability of MSCs can be usefully applied for the treatment of autoimmune and inflammation-related diseases such as asthma, rhinitis, and dermatitis. Therefore, MSCs has possibility as a new drug for AD.
