New hope for hair regrowth: High-Dose treatment trial for alopecia

NCT ID NCT06873945

Recruiting now Disease control Sponsor: Pfizer Source: ClinicalTrials.gov ↗

Summary

This study is testing whether a higher dose (100 mg) of the medication ritlecitinib is safe and works better than the standard 50 mg dose for treating severe alopecia areata, a condition that causes significant hair loss. It will involve about 550 participants aged 12 and older who have lost at least 50% of their scalp hair. Participants will be randomly assigned to take one of the two doses daily for about a year to compare hair regrowth results.
