Uppsala, Sweden – December 15, 2024 – Orexo AB (publ.), (STO:ORX) (OTCQX:ORXOY), today announces that it has entered into a settlement agreement with Sun to resolve the patent litigation regarding Zubsolv® (buprenorphine and naloxone) sublingual tablet (CIII), for the treatment of opioid use disorder in the US.

The agreement resolves the patent litigation commenced in 2020 by Orexo following Sun’s filing of an Abbreviated New Drug Application (“ANDA”) seeking approval to market generic versions of Zubsolv in the US prior to the expiration of Orexo’s patents listed in FDA’s Orange Book for Zubsolv.

The agreement allows Sun to enter the US market with its generic versions of Zubsolv in September 2030. Zubsolv is protected by ten patents in the US with expiration dates ranging from 2027 to 2032. This settlement agreement does not implicate its patent protection.
