PAION REPORTS POSITIVE HEADLINE DATA IN U.S. PHASE III TRIAL WITH REMIMAZOLAM FOR PROCEDURAL SEDATION UNDERGOING BRONCHOSCOPY
DGAP-News: PAION AG / Key word(s): Research Update PAION REPORTS POSITIVE HEADLINE DATA IN U.S. PHASE III TRIAL WITH REMIMAZOLAM FOR PROCEDURAL SEDATION UNDERGOING BRONCHOSCOPY – Primary efficacy endpoint successfully achieved – Phase III program successfully completed – Excellent safety profile of remimazolam confirmed – Conference call on remimazolam headline data on Thursday, 29 June 2017 at 2:00 p.m. CEST (1:00 p.m. GMT/8:00 a.m. EDT)
Dr. Wolfgang Söhngen, CEO of PAION AG, commented: “I would like to warmly thank the patients and clinicians who participated in the study. We are very excited about the remimazolam results announced today. With the successful completion of the bronchoscopy trial, we have achieved a significant milestone in PAION’s history and on the way to market approval for remimazolam.” This Phase III clinical trial – conducted at 15 sites throughout the U.S. – was a prospective, double-blind, randomized, placebo-controlled study with an open label midazolam arm in 446 patients (of which 431 received study medication) undergoing bronchoscopy for diagnostic or therapeutic reasons. The study was continuously supervised by an independent Data Monitoring Committee (DMC). In this trial 162 patients (37.6%) were ASA III patients (American Society of Anesthesiologists classification; ASA III: patients with severe systemic disease) and the average age of all patients was 62.3 years as compared to 6.6% ASA III patients and an average age of 54.9 years of all patients in the previously reported pivotal Phase III colonoscopy trial. Patients were randomized to receive either remimazolam, midazolam, or placebo in combination with fentanyl for pain control in order to achieve adequate sedation to start and perform the procedure. In order to ensure the performance of the scheduled bronchoscopy, midazolam was available for all patients as rescue medication for non-responders. The primary outcome measure was a composite endpoint defined as: no need for rescue medication, completion of the procedure and no more than 5 doses within any 15-minute window for remimazolam/placebo and no more than 3 doses within any 12-minute window for midazolam. The primary endpoint was reached in 82.5% of the patients treated in the remimazolam arm and 3.4% in the placebo arm (p-value of <0.0001). Important secondary endpoints included median time from start of medication to start of procedure (5.0 minutes in the remimazolam arm versus 17.0 minutes for placebo) and median time from end of procedure to return to full alertness (remimazolam 6.0 minutes versus placebo 14.0 minutes). Additionally, the patients’ subjective impression of time from last dose to “back to normal” was a median of 404 minutes for remimazolam versus 935 minutes for placebo. In the open label midazolam arm, procedural success was achieved in 34.8% of patients. Midazolam patients showed a median time from start of medication to start of procedure of 16.0 minutes and a median time from end of procedure to return to full alertness of 12.0 minutes. Additionally, time from last dose to “back to normal” as reported by patients on midazolam was a median of 478.5 minutes. Overview procedural results:
Overall adverse events, treatment-emergent adverse events and, in particular, incidents of hypotension and bradycardia occurred less frequently with remimazolam compared to midazolam. Hypotension was the most frequently reported adverse event occurring in 41.9% of patients treated with remimazolam, 62.7% with placebo and 49.3% with midazolam. Hypoxia occurred in 21.8% of patients given remimazolam, 20.3% in the placebo arm and 18.8% in the midazolam arm. As expected, patients enrolled in this trial were of overall poorer health compared to those enrolled in the pivotal colonoscopy trial. Twenty-one patients across all treatment groups experienced a total of 26 treatment-emergent serious adverse events (“SAE”). Out of these 26 SAEs, only two were considered related to treatment (remimazolam) and occurred in a single patient after administration of fentanyl at twice the dose allowed by the study protocol. “The study results suggest that remimazolam, the first drug in many years to be tested for use in providing procedural sedation in the bronchoscopy lab has the potential to enhance the options for bronchoscopy patients allowing for a more efficient procedure“, Gerard A. Silvestri M.D., M.S, Professor of Medicine, Medical University of South Carolina, Charleston, South Carolina, U.S., commented. “Remimazolam may be an ideal agent for patients who require bronchoscopy because it is safe, ultra-short-acting, has excellent sedative effects, and allows patients to more quickly wake to an alert state. The results of the trial are under further evaluation but already demonstrate that remimazolam is likely to have a place in providing adequate sedation to patients undergoing bronchoscopy.”

In clinical studies, remimazolam demonstrated efficacy and safety in over 1,500 volunteers and patients. Data so far indicate that remimazolam has a rapid onset and offset of action combined with a favorable cardio-respiratory safety profile. Remimazolam is currently in clinical Phase III development for procedural sedation in the U.S. After completion of the ongoing development, the implementation of a pediatric development plan already agreed with the FDA is planned. A full clinical development program for general anesthesia was completed in Japan, and a Phase II study in general anesthesia was completed in the EU. Based on the positive results of a Phase II study, development for ICU sedation beyond 24 hours is another attractive indication. About PAION PAION’s vision is to become an acknowledged “PAIONeer” in sedation and anesthesia. Contact Disclaimer:
