Pfizer Reports Positive P-III Results for LITFULO in Nonsegmental Vitiligo (NSV)
Shots:
- Pfizer reported positive topline results from the pivotal P-III TRANQUILLO and TRANQUILLO 2 studies evaluating LITFULO (ritlecitinib) in pts. with NSV. Both studies (n=2,174 pts) met their co-primary endpoints, demonstrating statistically significant improvements in facial and total body repigmentation vs. PBO at 52 wks. across 271 sites globally
- TRANQUILLO (n=607, ≥12yrs.) evaluated 50mg LITFULO and TRANQUILLO 2 (n=1567, ≥18yrs.) evaluated 50 or 100 mg LITFULO. Both the studies achieved F-VASI75 (≥75% improvement in Facial Vitiligo Area Scoring Index) and T-VASI50 (≥50% improvement in Total Vitiligo Area Scoring Index) with a consistent safety profile
- Based on these findings, Pfizer plans to pursue global regulatory filings for LITFULO as a potential oral systemic treatment for adults with NSV and initiate a pivotal 2026 study in moderate alopecia areata.
