Study to Assess Safety and Efficacy of AQUAVAN® Injection for Sedation During Cardiac Catheterization

Angioplasty Clinical Trial

Official title: A Phase III, Randomized, Open-Label Study to Assess the Safety and Efficacy of AQUAVAN® Injection Versus Midazolam HCl for Sedation in Patients Undergoing Percutaneous Coronary (PC) Procedures

Status Completed

Clinical Trial Summary

The anticipation of pain and discomfort, a diagnosis, and other intrinsic unknowns make patients anxious both prior to and during a procedure. Therefore, the main goal of sedation with analgesia used during various diagnostic, therapeutic, or surgical procedures is to relieve this anxiety, discomfort, and pain, which are all interrelated. The optimal level of sedation for any given patient is one that allows the patient to tolerate the procedure and provides an appropriate safety margin. This was a study designed to examine the safety and efficacy of AQUAVAN® Injection versus a commonly used approved sedative drug, midazolam HCl following pretreatment with fentanyl citrate injection (for pain relief) in producing sedation in patients undergoing single cardiac catheterization procedures.

Clinical Trial Description

This was a randomized, open-label study designed to assess the safety and efficacy of AQUAVAN® Injection (hereafter referred to as AQUAVAN) versus the reference drug, midazolam HCl (hereafter referred to as midazolam) following pretreatment with fentanyl citrate injection (hereafter referred to as fentanyl) in producing sedation in male and female patients undergoing single PC procedures.

Screening assessments were done within 2 weeks of scheduled procedures. After completion of preprocedural sedation assessments, patients were randomly assigned to 1 of the 2 treatment groups at a 3:1 (AQUAVAN: midazolam) allocation ratio on the day of the scheduled procedure (Day 0) via an Interactive Voice Response System (IVRS). Randomization was stratified by site.

All patients, regardless of treatment group assignment, received fentanyl as an analgesic pretreatment. Supplemental doses of fentanyl could be administered if the patient reported pain or if analgesia was inadequate, as demonstrated by increased heart rate and/or blood pressure in the presence of adequate sedation. At no time was fentanyl to be administered to increase sedation levels.

AQUAVAN or midazolam was administered by intravenous (i.v.) bolus to induce a state of minimal-to-moderate (procedural) s sedation, defined as a score of ≤4 on the Modified Observer's Assessment of Alertness/Sedation (OAA/S) scale. Supplemental doses were administered, if necessary, to increase the depth or duration of sedation. Supplemental doses were not administered if the Modified OAA/S score was ≤2 or if there was no purposeful response to stimulation. Patient and Investigator assessments were used to confirm that the depth of sedation met the goals of sedation, reduced anxiety, and awareness.

Follow-up patient assessments were conducted in a telephone interview 24 hours following treatment and during a clinic visit 2 to 5 days following treatment. ;
