A Study of 2 Doses of Ritlecitinib in People 12 Years of Age and Older With Alopecia Areata
This study is investigating a medicine called ritlecitinib for treating alopecia areata, a condition causing hair loss. Ritlecitinib is already approved in some countries at a 50mg dose. This study will compare that dose with a higher 100mg dose to see if it's also safe and effective. Researchers want to find out if the 100mg dose helps hair grow back and if it has any side effects. Participants, aged 12 and older with significant scalp hair loss due to alopecia areata, will take part. They will be randomly assigned to receive one of the doses, or a dummy pill (placebo), and will be observed for about 13 months with regular check-ups.
En un coup d'œil
De quoi parle cette étude ?
Alopecia areata is a common condition where the immune system mistakenly attacks hair follicles, leading to hair loss on the scalp, face, and sometimes other parts of the body. While there are some treatments available, researchers are always looking for new and effective options.
This particular study is focusing on a medicine called ritlecitinib. It's designed to help calm down the immune system's overreaction that causes hair loss. A 50mg dose of ritlecitinib is already used in many countries for severe alopecia areata in people aged 12 and above. Now, doctors want to see if a higher 100mg dose might be even more effective, while still being safe.
The main goal of this study is to compare the 50mg and 100mg doses of ritlecitinib. They want to check how well both doses work in helping hair grow back, as well as keeping a close eye on any potential side effects. By carefully studying these two doses, researchers hope to better understand the best way to use ritlecitinib to help people living with alopecia areata.

Qui peut être éligible ?
To join this study, you need to be at least 12 years old and have a clear diagnosis of alopecia areata. This means your doctor has confirmed your hair loss is due to this specific condition, and not something else. You must also have lost at least half of the hair on your scalp.
It's important that your hair loss specifically due to alopecia areata and not another medical issue. Also, your current episode of hair loss shouldn't have started more than 10 years ago. You must be willing to stop any other alopecia areata treatments you're currently using while you're in the study.
There are also some reasons why you might not be able to join. For example, if you have other conditions that cause hair loss, a history of serious allergic reactions to similar medicines, or certain infections, you might not be eligible. The study team will discuss all these details with you thoroughly to make sure taking part is safe and suitable for you.

En quoi consiste la participation ?
If you join this study, you'll be involved for about 13 months. During this time, you'll be asked to visit the study clinic up to 9 times. When you join, you'll be randomly assigned, like drawing names out of a hat, to receive one of the two doses of ritlecitinib (50mg or 100mg), or a dummy pill called a placebo. You'll take your assigned medicine by mouth once a day.
During your visits, the study team will carry out several checks. These will include assessing your hair loss, having physical examinations, hearing tests, and blood tests. You might also have an X-ray and an ECG (a test that checks your heart's electrical activity). They'll take photographs of your scalp and eyes to track any changes. You'll also be asked to fill in some questionnaires about your alopecia areata and how you're feeling.
