Introduction
In a significant breakthrough for dermatological treatments, Sun Pharmaceutical Industries Ltd. has secured legal clearance to launch its much-anticipated drug Leqselvi™ (deuruxolitinib) in the United States. Initially approved by the U.S. Food and Drug Administration (FDA) in mid-2024 for treating severe alopecia areata, Leqselvi’s commercial release was held back due to patent disputes with Incyte Corporation. However, with a recent ruling from the U.S. Court of Appeals, the path has now been cleared for Sun Pharma to make Leqselvi available to American patients. This move is poised to not only strengthen Sun Pharma’s global footprint but also bring hope to thousands suffering from autoimmune-related hair loss.
What is Leqselvi and How Does It Work?
Leqselvi is a JAK inhibitor, scientifically known as deuruxolitinib, designed to treat alopecia areata, an autoimmune condition causing hair loss on the scalp and body. The drug works by selectively inhibiting Janus kinase (JAK) enzymes, which play a key role in inflammatory signaling pathways.
Clinical trials under the THRIVE-AA1 and THRIVE-AA2 studies showed promising results. After 24 weeks of treatment, over 30% of patients achieved at least 80% scalp hair regrowth. These outcomes mark a revolutionary step forward for patients with moderate to severe alopecia, a condition that affects around 700,000 people in the U.S., including 300,000 with extensive symptoms.
Regulatory Hurdles and Legal Challenges
Although the FDA gave the green light for Leqselvi in July 2024, Sun Pharma faced legal resistance from Incyte Corporation, which holds a patent on a competing treatment. In November 2024, the U.S. District Court of New Jersey issued an injunction, halting the drug’s commercial launch.
However, Sun Pharma appealed the ruling, and on April 9, 2025, the U.S. Court of Appeals for the Federal Circuit overturned the injunction. This decision enables the company to move forward with its launch strategy, marking a major legal win for the Indian pharma giant.

Sun Pharma’s Expansion Strategy in the U.S.
Sun Pharma is India’s largest pharmaceutical company and has steadily been expanding its footprint in the U.S., which is one of the world’s largest drug markets. The successful launch of Leqselvi could be a game changer for the company’s U.S. dermatology portfolio.
The company has stated it will soon reveal a structured launch plan for Leqselvi, which could include partnerships with dermatologists, awareness campaigns, and support programs for patients. This expansion aligns with Sun Pharma’s long-term vision to become a global leader in specialty therapies.
A New Hope for Alopecia Areata Patients
Alopecia areata can have a deep psychological impact on patients, often leading to stress, anxiety, and low self-esteem. Until recently, treatment options were limited, with inconsistent results.
Leqselvi’s entry into the U.S. market offers a targeted and effective solution, potentially transforming the standard of care for alopecia patients. For many, this is more than just a drug launch—it represents a chance to reclaim confidence and quality of life.
What’s Next for Leqselvi and Sun Pharma?
With the legal barriers out of the way, all eyes are now on Sun Pharma’s launch timeline and pricing strategy for Leqselvi. Experts suggest the company might opt for a competitive pricing model to quickly gain market traction and patient adoption.
In the coming months, we can expect further announcements about availability, insurance coverage, and physician engagement programs, as Sun Pharma looks to establish Leqselvi as a go-to treatment in the alopecia segment.
Conclusion
The FDA approval and recent court ruling mark a turning point for Sun Pharma and patients battling alopecia areata. Leqselvi stands out not only as a medical advancement but also as a symbol of determination in overcoming legal and regulatory obstacles. As Sun Pharma prepares for a strategic rollout, the U.S. pharmaceutical landscape is set to witness a promising addition in the field of dermatology.
