Lee's Pharmaceutical Holdings Limited is acquiring the Staccato® One Breath Technology® (OBT®) platform and related assets, including global rights as licensor and manufacturer for Staccato® alprazolam, as part of an expanded partnership with UCB. The Staccato® OBT® platform is a proprietary inhalation technology with applications in central nervous system and neurodegenerative disorders, already validated by the approved product Adasuve® and several late-stage development programs. This transaction will also integrate two Phase 2 clinical-stage CNS assets targeting Parkinson's disease and Cyclic Vomiting Syndrome into Lee's Pharm's portfolio. Upon completion, Lee's Pharm and its partner NPI stand to receive up to US$60.5 million in milestone payments, as well as tiered royalties and manufacturing revenue from global sales of Staccato® alprazolam. The transaction is expected to close by the end of 2025, subject to certain conditions.
