AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
LITFULO (ritlecitinib) is an oral small-molecule JAK3 and TEC kinase inhibitor approved in June 2023 for multiple immune-mediated conditions including alopecia areata, vitiligo, chronic spontaneous urticaria, hidradenitis suppurativa, mycosis fungoides, sezary syndrome, keloid, type 1 diabetes, and celiac disease. The drug irreversibly blocks ATP binding at JAK3 and TEC kinase family members, inhibiting cytokine-driven STAT phosphorylation and immune receptor signaling. Ritlecitinib represents Pfizer's entry into the high-potential JAK/TEC inhibitor space with a novel kinase selectivity profile.
