Hyloris announces potential registration date for Maxigesic® IV in the US

• PDUFA goal date set for 17 October 2023 by U.S. Food & Drug Administration
• Exclusive commercial partner for Maxigesic® IV in the U.S. is Hikma Pharmaceuticals, a leading supplier of complex, injectable hospital products

Liège, Belgium – 2 May 2023 – 7AM CET – Non-regulated information - Hyloris Pharmaceuticals SA (Euronext Brussels: HYL), a specialty biopharma company committed to addressing unmet medical needs through reinventing existing medications, today announces the US Food & Drug Administration has set 17 October 2023 as the date by which it expects to respond to the application regarding Maxigesic® IV.

The US regulatory body confirmed it has received a complete response in relation to its questions on extractables and leachables from Maxigesic® IV’s primary packaging – the glass vial and the stopper in which the drug product is stored. The FDA requested additional data in July 2022.

Hyloris’ partner AFT Pharmaceuticals ("AFT”) submitted the additional data to the FDA on 17 April 2023. The Prescription Drug User Fee Act (PDUFA) goal date of 17 October 2023 set by the FDA confirms the anticipated review period of 6 months, and a potential registration of Maxigesic® IV for the US market before the end of 2023.

Sales could follow soon after, with an exclusive license and distribution agreement already signed between AFT and Hikma Pharmaceuticals ("Hikma”). Hikma is a leading supplier of complex, injectable hospital products in the U.S.

Under the terms of the development collaboration agreement between Hyloris and AFT, Hyloris is eligible to receive a share on any product-related revenues, such as license fees, royalties, milestone payments, received by AFT.

About Maxigesic® IV

Maxigesic® IV is a novel, dual mode-of-action, non-opioid pain treatment for use post-operatively in hospitals or when patients cannot take medicine orally. It is a unique combination of 1000mg paracetamol with 300mg ibuprofen solution for infusion, thereby reducing both pain and inflammation.

Results from a randomized, placebo-controlled Phase 3 trial demonstrated that Maxigesic® IV was well-tolerated and had a faster onset of action, offered higher pain relief, and provided the potential to reduce the use of opioids compared to ibuprofen IV or paracetamol IV alone in the same doses. Further exposure studies have demonstrated the drug’s efficacy and safety in an expanded population group over a longer treatment period. Maxigesic® IV is protected by several granted and pending patent applications.
