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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Subjects of any gender, age 18 years or older, at the time of informed consent at Screening
* Subjects who are willing and able to adhere to the study visit schedule and comply with protocol requirements.
* Subject self-reports active CA (LPP/FFA or CCCA). for at least 6 months from screening visit. Diagnosis will be confirmed clinically at screening visit.
* Subject has a negative Tuberculin purified protein derivative (PPD) or QuantiFERON TB-Gold test (QFT) at screening.
* Subject is judged to be in otherwise good overall health following a detailed medical and medication history, physical examination, and laboratory testing.
Exclusion Criteria:
* Subject's cause of hair loss is indeterminable and/or they have concomitant causes of alopecia, such pregnancy-related, drug-induced, telogen effluvium, or advanced androgenetic alopecia.
* Subject has a history of CA for ≥ 7 years since their disease onset, severe fibrosing disease, or very rapid hair loss.
* Subject has a history of moderate to severe keloids on the scalp, as determined by clinical examination at screening.
* Other scalp disease that may impact assessment (eg, scalp psoriasis, dermatitis, etc).
* Subject is pregnant or breastfeeding. Female subjects of childbearing potential must agree to use two effective methods (one of which is a highly effective method) of contraception throughout the study and for at least 28 days after the last dose of investigational product. Women of childbearing…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
