A 104-Week Study of Ritlecitinib Oral Capsules in Adults With Nonsegmental Vitiligo (Active and Stable) Tranquillo 2
This research study is investigating an oral medicine, ritlecitinib, for vitiligo, a condition where the skin loses its colour in patches. The study aims to understand how safe and effective ritlecitinib is for adults with nonsegmental vitiligo, which can affect both sides of the body. Currently, there are no approved oral medications for this type of vitiligo. Participants will be randomly given ritlecitinib or a dummy capsule (placebo) in one part of the study, lasting about 26 months, or receive only ritlecitinib in another part, lasting about 14 months. The study will involve various health checks, questionnaires, and photographs to monitor progress and safety.
A colpo d'occhio
Di cosa tratta questo studio?
This study is called Tranquillo 2, and it's looking into a new oral medicine called ritlecitinib. The main goal is to find out if ritlecitinib is a safe and effective treatment for nonsegmental vitiligo in adults. Vitiligo is a skin condition where the cells that give your skin its colour are destroyed, leading to white patches. Nonsegmental means these patches can appear on both sides of your body, for example, on both knees or both hands.
Ritlecitinib has been tested in earlier studies and has shown a promising safety profile. It’s important to remember that at the moment, there aren't any approved medicines that you can take by mouth specifically to treat nonsegmental vitiligo. This study hopes to provide more information on whether ritlecitinib could fill this gap.
The study is divided into two main parts. In Part I, some participants will receive different doses of ritlecitinib, while others will receive a placebo – a capsule that looks like the study medicine but contains no active ingredient. This helps researchers compare the effects. In Part II, everyone will receive ritlecitinib. By comparing the experiences of people taking ritlecitinib with those who don't, the researchers can learn if the medicine is safe and if it helps improve vitiligo.

- Participants will either be given ritlecitinib or a placebo, or only ritlecitinib depending on the study part.
- The study lengths vary from about 14 to 26 months, with regular clinic visits.
- Various health checks, photos, and questionnaires will be part of the process.

Chi può essere idoneo?
This study is looking for adult volunteers, aged 18 or older. To be considered, you must have been diagnosed with nonsegmental vitiligo for at least three months.
Your vitiligo also needs to cover a certain amount of your body, including some areas on your face, but not include the palms of your hands or soles of your feet. You might have 'active' vitiligo (meaning it's currently changing or spreading) or 'stable' vitiligo (where it's not changing much).
If you're currently using other treatments for your vitiligo, you'll need to be ready to stop them if you join the study. The study team will be able to tell you if the study is right for you after checking all your health details.
Questo studio potrebbe fare al caso tuo?
Rispondi a queste domande rapide per vedere se potresti essere idoneo. Questo è solo una guida — il team di ricerca prende la decisione finale.
- Hai 18 anni o più?
- Have you been diagnosed with nonsegmental vitiligo for at least 3 months?
- Are you willing to stop any other vitiligo treatments?
- Does your vitiligo affect a certain amount of your body, including some on your face (but not just palms/soles)?
- Are you able to attend regular study visits for over a year (up to 26 months)?
Cosa comporta la partecipazione?
If you join the study, you'll be assigned by chance to one of the treatment groups – like drawing names from a hat. In Part I, you could receive one of two different doses of ritlecitinib or a dummy capsule (placebo) once a day. If you're in the placebo group and your vitiligo hasn't responded after 52 weeks, you'll then switch to taking ritlecitinib for the rest of the study. In Part II, all participants will receive a specific dose of ritlecitinib.
Participation in Part I will last about 26 months, involving at least 17 visits to the study site. If you're in Part II, it will be around 14 months with at least 11 visits. During these visits, you'll have various health checks, such as physical exams, blood tests, hearing tests, an X-ray, and an ECG (heart check). They'll also take photographs of your vitiligo patches and ask you to complete questionnaires about your condition.
