Litfulo (ritlecitinib) met coprimary endpoints in two phase 3 studies, demonstrating clinically meaningful improvements in nonsegmental vitiligo on the face and body for adults and adolescents aged 12 and older, according to a Pfizer press release issued following the TRANQUILLO clinical development program.
The recent topline data from Pfizer’s phase 3 clinical trials offer a look at how ritlecitinib might be used for both adult and adolescent patient populations.
In Plain English: The Clinical Takeaway
- What was tested: A once-daily dose of ritlecitinib (marketed as Litfulo) was evaluated in phase 3 trials for nonsegmental vitiligo affecting the face and body.
- Who is affected: The studies included adults and adolescents aged 12 years and older.
- What happens next: Backed by these positive topline results from the TRANQUILLO program, Pfizer plans to submit global regulatory filings for ritlecitinib (Litfulo) as a treatment for nonsegmental vitiligo.
