This study is testing a medicine called baricitinib to see if it helps kids aged 6 to less than 18 who have severe hair loss, known as alopecia areata (AA). The study has four parts, starting with a 5-week screening to check if you can join, then 36 weeks where you might get the medicine or a fake pill (placebo) without knowing which, followed by about a 2-year period where everyone gets the medicine, and a final 4-week check-up.
To join, you need to have had severe AA for at least 1 year. You can't join if your hair loss is from other reasons, like a disease or being bedridden. Also, if you have certain health issues, like uncontrolled high blood pressure or infections like hepatitis or HIV, you can't join.
Key Points:- This study lasts for about 3 years in total.
- Participation involves taking medicine and regular doctor visits.
- You must have tried at least one other treatment for AA before.
