PAION was formed in 2000 in Aachen. Since its inception, the founders, Mariola Söhngen, MD and Wolfgang Söhngen, MD focused on the clinical development of CNS compounds.
PAION took over the development of Remimazolam as a pre-IND candidate in 2008 and has successfully developed it to a Phase III compound. Following successful funding activities (EUR 61 million) in 2014, a Phase III program has been initiated in 2015 EU and US global registration. In 2017 the remimazolam Phase III development program in the U.S. in procedural sedation has been completed. First market approval followed in 2020 first in Japan, followed by the U.S. and China.
Until 2008, PAION's focus was on stroke with Desmoteplase for which all remaining rights were sold to Lundbeck in 2012 in order to accelerate the development of Remimazolam.
