This study was designed to assess the safety and efficacy of AQUAVAN® Injection in providing adequate sedation in patients undergoing colonoscopy. Prior to the procedure, patients received fentanyl citrate for pain management followed five minutes later by AQUAVAN® Injection for sedation. Throughout the procedure, study personnel assessed the patient's vital signs and depth of sedation. After the procedure, the patient, physician, and an evaluator were asked to complete satisfaction surveys.
Primary Outcome Measures:
- The primary efficacy objective was to determine the desired sedative dose/dose range and dosing paradigm of AQUAVAN, defined as one that consistently provided mild-to-moderate sedation (Modified OAA/S >=2 and <=4) in a majority of patients.
Secondary Outcome Measures:
- Efficacy variables included: time to sedation, time to Fully Alert, time to Fully Recovered, time to Ready for Discharge, Modified OAA/S scores over time, number of doses and amount of AQUAVAN, and Patient and Physician Satisfaction Surveys.

Randomized, open label, multi-center, adaptive dose ranging study, in which several dose levels of AQUAVAN® Injection and fentanyl citrate injection will be investigated to produce a desired sedation level in patients undergoing elective colonoscopy. A desired sedative dose/dose range and dosing paradigm will be identified based on pre-set criteria using the Modified Observer's Assessment of Alertness/Sedation (OAA/S). The desired sedative dose/dose range and dosing paradigm of AQUAVAN® Injection is defined as one that consistently provides mild to moderate sedation (Modified OAA/S between 2 and 4 inclusive) in a majority of patients who are pre-medicated with fentanyl citrate injection.
