Efficacy and Safety of Expanded UCMSCs On Patients With Moderate to Severe Psoriasis

Study Purpose

The purpose of this study is to evaluate the efficacy and safety of Expanded Umbilical Cord Mesenchymal Stem Cells on patients with moderate to severe psoriasis. Any adverse events related to UCMSCs infusion will be monitored.The primary outcome is the improvement rate of PASI(Psoriasis Area and Severity Index) and treatment response will be computed from PASI before and after UCMSCs infusion.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03745417
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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. Umbilical cord Mesenchymal Stem Cells were isolated from umbilical cord matrix 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 UCMSCs could be beneficial for treatment of moderate to severe psoriasis.
