Zydus Lifesciences Subsidiary Sentynl Therapeutics Signs Option Agreement for Alvelestat in AATD-LD
Zydus Lifesciences' subsidiary, Sentynl Therapeutics, has an option and license agreement with Mereo BioPharma for alvelestat in AATD-LD. Sentynl can acquire U.S. commercial rights and global manufacturing rights. Mereo may receive up to $40 million in payments and double-digit royalties upon option exercise. Phase 3 development could start in early 2027.
This is a strategic partnership for a potential new drug in a rare disease segment. While positive, its impact will depend on the successful development and commercialization of alvelestat, which is still in the early stages (Phase 3 planning).
The agreement expands Sentynl's rare disease portfolio with a promising drug candidate, alvelestat, and offers potential financial benefits to Mereo BioPharma, indicating a positive development for both companies.
Zydus Lifesciences Limited announced that its wholly-owned subsidiary, Sentynl Therapeutics, Inc., has entered into an option and license agreement with Mereo BioPharma Group plc for the U.S. commercial and global manufacturing rights to alvelestat, a potential first-in-class oral treatment for Alpha-1 Antitrypsin Deficiency-Associated Lung Disease (AATD-LD).
Under the agreement, Sentynl has the exclusive right to acquire a license to commercialize alvelestat in the United States, while Mereo retains commercial rights in the rest of the world. Sentynl will also have global manufacturing rights for alvelestat. If the option is exercised, Sentynl will provide funding for the alvelestat Phase 3 development program, which could commence in early 2027. Mereo will receive a non-refundable option fee and, upon option exercise, is eligible for up to $40 million in upfront and R&D payments until NDA filing, along with double-digit tiered royalties on U.S. sales. Mereo will lead the global Phase 3 study and regulatory interactions until its completion.
Dr. Sharvil P. Patel, Managing Director of Zydus Lifesciences Limited, highlighted that this partnership significantly expands Sentynl’s rare disease portfolio with a promising candidate that addresses a substantial unmet need. Matt Heck, CEO of Sentynl Therapeutics, emphasized the agreement's role in expanding their focus to a larger rare disease population. Denise Scots-Knight, CEO of Mereo BioPharma, expressed enthusiasm for partnering with Sentynl to advance alvelestat, noting the companies' collaboration to refine the Phase 3 study design during the option period.
Alvelestat is a novel, oral small molecule designed to inhibit neutrophil elastase, a key enzyme involved in lung tissue inflammation and destruction. It has received Orphan Drug Designation and Fast Track designation from the FDA and the European Commission for AATD-LD. The estimated prevalence of AATD-LD in the United States is approximately 50,000-80,000 individuals. The companies will collaborate to refine the Phase 3 study design during the short option period.
