A Pilot Study to Assess Safety and Biomarker Responses of the Dual JAK1/TYK2 Inhibitor for Cicatricial Alopecia

In Brief

A Phase 2 clinical trial evaluating PF-06700841 and Placebo for Cicatricial Alopecia. Completed, enrolled 51 participants across 1 site.

Detailed Summary

Alopecia could be subdivided into two main groups of diseases: non-scarring alopecia, such as male pattern baldness, or alopecia areata (AA), in which hair follicles are preserved, yet quiescent, and scarring alopecia, also known as cicatricial alopecia (CA), in which hair follicles are irreversibly destroyed. CA leads to scarred areas, most commonly on the scalp, that cannot re-grow hair. Despite being a long-term condition, that often has significant impact on patients' well-being, available effective treatments for these diseases are lacking. In addition, the molecular abnormalities causing CA are largely unknown. The study team's research involves administrating patients a new investigational drug (a combined TYK/JAK inhibitor) which has been shown to be safe and well tolerated in clinical studies to date, and is being investigated in other conditions, such as AA. CA patients will be asked to provide small samples of skin and blood throughout the treatment period, to find out how they respond to the drug, and to attempt to better understand these diseases.
