PAION receives UK MHRA approval of Byfavo® (remimazolam) for the induction and maintenance of general anesthesia in adults

Aachen (Germany), 31 August 2023 - PAION AG (ISIN DE000A3E5EG5; Frankfurt Stock Exchange, Prime Standard: PA8), a specialty pharmaceutical company with innovative compounds for use in outpatient and in-hospital sedation, anesthesia and intensive care, today announces that the UK Medicines & Healthcare products Regulatory Agency (MHRA) has approved Byfavo^® (remimazolam) for the induction and maintenance of general anesthesia in adults. The decision follows the approval of the European Commission in the EU (covering the European Economic Area (EEA) countries) from April 2023.

Gregor Siebert, CEO of PAION AG, commented: “We are excited that the MHRA has approved Byfavo^® for the induction and maintenance of general anesthesia in adults. This further expands the growth opportunities for PAION in the area of general anesthesia. We are currently preparing for the UK launch, which will take place during the 2023 AAGBI Annual Congress in Edinburgh, September 13-15, including a scientific symposium on Byfavo^® in general anesthesia on 14 September 2023. The UK is one of Europe’s strongest markets and we have good expectations for the uptake of Byfavo^® in this key market.”

The MHRA approval is based on the data from a comprehensive clinical program in general anesthesia. This demonstrated, among other things, a lower incidence of hemodynamic side effects compared with propofol. Byfavo^® was already approved in the EU, Japan, the Philippines and South Korea for general anesthesia.

About Byfavo^®

Byfavo^® (remimazolam) is an ultra-short-acting intravenous benzodiazepine sedative and anaesthetic. In humans, Byfavo^® is largely degraded to an inactive metabolite by hepatic esterases, a widely distributed type of enzyme, rather than by cytochrome-dependent degradation pathways in the liver. As with other benzodiazepines, an antidote is available in flumazenil for rapid reversal of the patient's sedation or anesthesia if needed. Data show that Byfavo^® has a rapid onset of action and a rapid recovery, with a favorable cardiorespiratory safety profile.

Byfavo^® is partnered in the USA (trade name BYFAVO^TM) with Eagle Pharmaceutical, in Japan (trade name Anerem^®) with Mundipharma, in South Korea (trade name Byfavo^TM) and Southeast Asia with Hana Pharm, in Latin America with Cristália and in Taiwan with TTY Biopharm. In addition, PAION has distribution partnerships with Viatris for Belgium, Poland, France and Romania as well as the Southern European countries Italy, Spain and Greece and in Eastern Europe (Estonia, Latvia and Lithuania, Czech Republic, Slovakia, Hungary, Croatia, Slovenia and Bulgaria) with Medis. These markets are currently not served by PAION itself.
