- Primary endpoint met: remimazolam demonstrated non-inferiority to propofol for anesthetic effect

- Key secondary endpoint met: remimazolam demonstrated superior hemodynamic stability compared to propofol

- EU Phase III program completed; data to serve as basis for MAA submission in general anesthesia

Aachen (Germany), 19 November 2020 - The Specialty Pharma Company PAION AG (ISIN DE000A0B65S3; Frankfurt Stock Exchange Prime Standard: PA8) today announces positive topline data from the pivotal remimazolam EU Phase III trial in general anesthesia. In the trial with 424 patients, remimazolam met both the primary and key secondary endpoints.

The randomized, single-blind, propofol-controlled, confirmatory Phase III trial enrolled 424 ASA III/IV patients (American Society of Anesthesiologists classification III to IV) undergoing planned surgery at more than 20 European sites.

The primary objective of the trial was to demonstrate non-inferiority of remimazolam compared to propofol for the induction and maintenance of general anesthesia during elective surgery. The primary efficacy endpoint was defined as the anesthetic effect of remimazolam and propofol assessed as a percentage of time of a Narcotrend (NCT) index below 60 (depth of anesthesia) during the maintenance phase of general anesthesia. In the final analysis, non-inferiority was demonstrated with an NCT index below 60 with 95.7% (n=235) of the time with remimazolam and 99.1% (n=92) with propofol at a significance level of p=0.0001.

The key secondary objective was to show improved hemodynamic stability compared to propofol. Hemodynamic stability is measured by avoidance of intraoperative drop in mean arterial blood pressure (MAP) between start of anesthesia and 15 minutes after the first skin incision, as well as usage of vasopressors. Although adjustments in the statistical testing were required based on the nature of the obtained data, a statistically significant superior hemodynamic stability of remimazolam compared to propofol could be shown with a number of hemodynamic events per patient of 62.62 ± 39.46 (n=270) with remimazolam and 71.03 ± 41.12 (n=95) with propofol at a significance level of p=0.0151.
