ADMSP: Safety and Efficacy of Expanded Allogeneic AD-MSCs in Patients With Moderate to Severe Psoriasis
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety and efficacy of Adipose-derived Mesenchymal Stem Cells (AD-MSCs) with moderate to severe psoriasis. Any adverse events related to AD-MSCs infusion will be monitored. Safety is assessed using incidence of Adverse Events(AEs) and Serious Adverse Events (SAEs). Efficacy is assessed via the proportion of the improvement of PASI (Psoriasis Area and Severity Index), relapse rate in treatment period, changes in PASI score and BSA, as well as DLQI.

Detailed Description
Psoriasis is an immune-mediated, genetic disease manifesting in the skin or joints or both. Numerous topical and systemic therapies are available for the treatment of psoriasis. Treatment modalities are chosen on the basis of disease severity, relevant comorbidities, patient preference. For moderate to severe psoriasis, phototherapy, systemic therapy and biologic immune modifying agents are recommended, but all of them have some drawbacks or limitations. Until now, no curative treatment is available. Therefore, it is important to find new treatment for psoriasis.
Mesenchymal stem cells (MSCs) are a kind of adult stem cells that can differentiate into bone, cartilage and adipose cells. Adipos-derived Mesenchymal Stem Cells(AD-MSCs) were isolated from fat tissues and were reported to treat moderate to severe psoriasis vulgaris and psoriasis arthritis successfully by case reports. For the mechanism of the disease, involvement of the immune system in psoriasis is now widely accepted. Mesenchymal stem cells (MSCs) are found to have the function of immunomodulation, migration to skin lesions, limitation of autoimmunity. Therefore, investigators supposed that the injection of AD-MSCs could be beneficial for treatment of moderate to severe psoriasis.
