Indivior PLC a leading addiction treatment company, announced that it has gained exclusive global rights to develop, manufacture, and commercialize Alar Pharmaceuticals Inc.'s ("Alar") portfolio of long-acting injectable formulations that release a prodrug1 of buprenorphine at varying durations, including its lead long-acting injectable ("LAI") candidate, ALA-1000.
ALA-1000 is a sustained-release LAI prodrug of buprenorphine. With dosage intervals of potentially up to four times per year, ALA-1000 could address unmet opioid use disorder ("OUD") patient needs with a longer duration of treatment, which could provide an option for patients seeking a less frequent maintenance therapy regimen, for patients living in remote areas without easy access to care, and for high-risk patients, such as those transitioning from the Justice system.
Under the agreement with Alar, Indivior will pay $10 million to secure exclusive global rights to develop, manufacture and commercialize ALA-1000 and Alar's future buprenorphine-based LAI product candidates. The $10 million payment is in addition to an initial $5 million option payment made by Indivior to Alar in Q1. Alar is entitled to potential milestone payments if various developmental, regulatory, and commercial goals are achieved.
"Alar provides Indivior with a unique opportunity to further address unmet patient needs in the treatment of OUD with potentially the first three-month buprenorphine LAI," said Christian Heidbreder, Chief Scientific Officer. "By providing a therapeutic option for patients who might benefit from less frequent dosing, ALA-1000 has the potential to broaden the spectrum of care for OUD treatment as well as enhance the addressable patient population."
ALA-1000 is an investigational drug and is positioned to be the first three-month buprenorphine administered subcutaneously entering the clinical stage. Results from a single-ascending dose ("SAD") study, announced by Alar in January 2022, demonstrated the safety, tolerability and sustained release profile of ALA-1000 over 12 weeks in patients with OUD2. Alar has been granted composition of matter and formulation patents for ALA-1000 covering sustained-release buprenorphine formulations with expiry in 2037 and 2039.
Based in Taichung, Taiwan, Alar is a drug development company which focuses on developing long-acting drug products for central nervous system ("CNS") disorders and chronic diseases, utilizing its proprietary depot technology. Compared with other long-acting subcutaneous injection technologies, its proprietary platform has been associated with distinctive characteristics such as low viscosity solution, small injection volume and sustained drug release profile.
The transaction is not expected to have a material impact on the Group's FY 2023 adjusted results.
