Detailed Description
JAK inhibitors are a group of small molecules, recently emerging as an appealing class of immune modifiers in dermatology. These are antagonists of the various members of the JAK enzymes family, which consists of JAK1, JAK2, JAK3, and tyrosine kinase-2 (TYK2). JAKs enable the binding and activation of the transducer and activator of transcription (STAT), by phosphorylating the cytoplasmic domain of multiple cytokine receptors. This results in translocation of the STAT into the nucleus, which greatly affects transcription. JAK antagonism therefore blocks this signaling through STAT activation, targeting Th1/IFN-γ as well as common γc cytokines (shared between IL-2, IL-4, IL-9, IL-7, IL-15 and IL-21), and TYK2 also adds an IL-23 capability. Therefore PF-06700841, a dual inhibitor of JAK1 and TYK2, currently being investigated for a number of indications including psoriasis, Crohn's disease, ulcerative colitis, psoriatic arthritis, atopic dermatitis, psoriasis, systemic lupus erythematosus and AA, and which has been shown to be safe and well tolerated, with good safety profile, was chosen for this protocol.
The study team will evaluate scalp and blood markers of inflammation, hair keratins and fibrosis, and our ultimate goal would be to elucidate the relations between inflammation and tissue scarring. While the study design is specifically powered to detect mechanistic tissue effects of PF-06700841, drug safety and tolerability in this patient population will also be closely monitored.
The study team's research proposal is novel in that the team proposes to investigate the immune profile of CA patients in skin and blood, at baseline, as well as during treatment with PF-06700841. In addition to the much-needed, prospective investigation of a new treatment modality for these diseases, the study team also aims to better characterize these diseases molecularly, and attempt to determine the effects of the inflammatory process on the resultant fibrosis. These findings will help to identify new treatment targets as well as direct further investigation for the development of new therapies for these disfiguring diseases.

A history of additional risk factors for Torsades de Pointes (TdP) (e.g. heart failure, hypokalemia, family history of long QT syndrome).
- If QTcF exceeds 450 mS, or QRS exceeds 120 mS, the ECG should be repeated 2 more times and the average of 3 QTc or QRS values should be used to determine the participants' eligibility.
