Dose-Finding Safety Study Evaluating Remimazolam (CNS 7056) in Patients Undergoing Diagnostic Upper GI Endoscopy

Endoscopy Clinical Trial

Official title:
A Phase IIa, Randomized, Controlled, Double-Blind, Dose-Finding Study Evaluating the Safety and Pharmacodynamics of CNS 7056 in Patients Undergoing Diagnostic Upper GI Endoscopy

Clinical Trial Summary

The purpose of this study was to assess the safety and efficacy of CNS 7056 as a procedural sedative at three dose levels compared to midazolam during a diagnostic upper GI endoscopy.

Clinical Trial Description

This was a randomized, double-blind, parallel-group, dose-finding study assessing the safety and efficacy of three dose levels of CNS 7056 compared with midazolam in patients undergoing diagnostic upper GI endoscopy.

Patients who met all study entry criteria and completed screening procedures were randomly assigned to 1 of 4 treatment groups: CNS 7056 0.10 mg/kg,0.15 mg/kg, or 0.20 mg/kg; or midazolam 0.075 mg/kg. Patients received their assigned treatment administered as a single intravenous injection by a syringe driver over 1 minute. The endoscopy started when a Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score of ≤3 has been reached, but no earlier than 90 seconds after Time 0 (the start of study drug injection). Rescue with sedative medication (midazolam 1-2 mg) was be permitted at the discretion of the administering physician.

Efficacy assessments consisted of the MOAA/S scores, Aldrete scores, and drowsiness measures using a Visual Analogue Scale (VAS). Cognitive function was assessed by the Hopkins Verbal Learning Test-Revised™ (HVLT-R™) and memory for the procedure by the Brice Questionnaire.

Safety assessments included adverse events, physical examinations, vital signs, ECGs, pulse oximetry measurements, clinical laboratory tests, and pain on injection using a VAS. ;
