1. FDA Approval: Sun Pharmaceutical Industries has received approval from the US Food and Drug Administration (FDA) for Leqselvi, an oral Janus kinase (JAK) inhibitor for the treatment of severe alopecia areata.
2. Alopecia Areata: Alopecia areata is an autoimmune disorder characterized by the immune system targeting hair follicles, leading to sudden and patchy hair loss.
3. JAK Inhibitor Mechanism: Leqselvi functions by inhibiting the activity of Janus kinase enzymes, which regulate inflammation and immune responses.

5. Market Competition: Leqselvi is the third FDA-approved alopecia areata drug, following Eli Lilly's Olumiant and Pfizer's JAK inhibitor.
6. Safety Concerns: Leqselvi carries a boxed warning regarding severe adverse events, including malignancies, major cardiovascular events, and thrombosis.
7. Revenue Projections: Leqselvi is expected to generate $253 million by 2030, according to GlobalData's Intelligence Center.
8. Dermatology Sector: The approval marks a significant expansion of Sun Pharma's dermatology sector, offering a new treatment option for patients with severe alopecia areata.
