Clinical Application of Stem Cell Educator Therapy in Alopecia Areata
Study Details
Study Description
Brief Summary
Alopecia areata (AA) is a common autoimmune disease that results in loss of body hair in varying degrees. The condition is estimated to affect more than 6.5 million people in the United States alone (naaf.org), with a worldwide prevalence of 0.1% to 0.2% and calculated lifetime risk of 2%. AA is the most common form of the disease, in which areas of complete hair loss arise within normal hair-bearing skin. Other forms include alopecia totalis (AT), characterized by total loss of scalp hair, and alopecia universalis (AU), characterized by complete loss of body hair. AA and its variants can have devastating effects on patients' quality of life and social functioning. At present, curative therapy for AA does not exist. Therapeutic options are currently very limited, such as intralesional injections of glucocorticoids and induction of allergic contact dermatitis. These therapies are not effective for many patients and are generally impractical for patients with diffuse AA, AT or AU. Recently, Janus kinase (JAK) inhibitors were effective for the treatment of severe AA. However, for those patients who do respond, relapses are common after discontinuation of treatment, due to the existing of autoimmune memory T cells. Stem Cell Educator (SCE) therapy, which uses only autologous mononuclear cells that are externally exposed to cord blood stem cells, has previously been proven safe and effective in subjects for the improvement of type 1 diabetes (T1D), T2D and other autoimmune diseases such as alopecia areata. Minoxidil is the FDA approved drug for the treatment of androgenetic alopecia (AGA) in 1988. This trial will explore the therapeutic potential of Stem Cell Educator therapy for the treatment of AA in combined with oral minoxidil.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Haire regrowth by SCE AA subjects will receive Stem Cell Educator therapy combined with oral minoxidil. Hair regrowth will be evaluated during one-year follow-up studies. |
Combination Product: Stem Cell Educator therapy combined with minoxidil
AA subjects will be recruited and initially primed with oral minoxidil for 30 days, and followed by the treatment with SCE therapy.
|
| Experimental: Minoxidil therapy Control subjects will receive treatment with topical 5% minoxidil |
Combination Product: Stem Cell Educator therapy combined with minoxidil
AA subjects will be recruited and initially primed with oral minoxidil for 30 days, and followed by the treatment with SCE therapy.

Outcome Measures
Primary Outcome Measures
- The percentage change in scalp hair growth. [Hair regrowth will be evaluated at different time points post receiving Stem Cell Educator therapy in 1, 3, 6, 9, and 12 months.]
The primary endpoint was the percentage change in scalp hair growth, measured with the Severity of Alopecia Tool (SALT) score.
Secondary Outcome Measures
- Feasibility of SCE therapy combined with minoxidil [12 months]
The feasibility will be determined by the number of patients who were unable to complete SCE Therapy.
- Preliminary efficacy of SCE therapy combined with minoxidil [12 months]
This will be determined by the duration of maintaining hair growth following SCE therapy.
- Efficacy of modulation of autoimmune-related memory T-cell markers [12 months]
Measurements of immune markers' changes will be preformed by flow cytometry such as CD8+CD45RO+CCR7- effector memory T cells. Peripheral blood mononuclear cells (PBMC) will be collected at 1, 3, 6, 9, 12 month post the SCE therapy.
- Feasibility of SCE therapy combined with minoxidil [12 month]
The number of patients who are lost to follow-up prior to the 12-month follow-up visit.
