A Study of AQUAVAN® Injection Versus Midazolam HCl for Sedation in Patients Undergoing Elective Colonoscopy

November 6, 2008 updated by: Eisai Inc.

A Phase III, Randomized, Open-Label Study to Assess the Safety and Efficacy of AQUAVAN Injection Versus Midazolam HCl for Sedation in Patients Undergoing Colonoscopy Procedures

This study was designed to demonstrate that AQUAVAN® is effective in providing adequate sedation in patients undergoing colonoscopy as well as to assess the safety profile of AQUAVAN versus that of midazolam. 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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized, open-label study designed to assess the safety and efficacy of AQUAVAN® Injection versus midazolam HCl following pretreatment with an analgesic, fentanyl citrate injection, in producing sedation in patients undergoing colonoscopy. Randomization will be stratified by site. Following completion of pre-procedure sedation assessments, patients will be randomly assigned to 1 of the 2 i.v. treatment groups at a 3:1 (AQUAVAN® Injection: midazolam HCl) allocation ratio. All study patients, irrespective of treatment group assignment, will receive fentanyl citrate injection as an analgesic pretreatment. Supplemental doses of fentanyl citrate injection may be administered if the patient reports pain or if inadequate analgesia is present as demonstrated by increased heart rate and/or blood pressure in the presence of adequate sedation. At no time should fentanyl citrate injection be administered to increase sedation levels. AQUAVAN® Injection and midazolam HCl will be administered to induce a state of adequate sedation, defined as a Modified Observer's Assessment of Alertness / Sedation (OAA/S) score of 4 or less. Supplemental doses will be administered to increase depth or duration of sedation. Supplemental doses will not be administered if the Modified OAA/S score is 2 or less or if there is no purposeful response to stimulation. The depth of sedation will be measured by the Modified OAA/S scale, a validated measure. Patient and Investigator assessments will be used to confirm the depth of sedation provided met the goals of sedation, reduction of anxiet, and reduced awareness.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patient provided a signed/dated Informed Consent and HIPAA authorization after receiving a full explanation of the extent and nature of the study;
  • Patient, if female, were surgically sterile, postmenopausal or non-pregnant and non lactating using an acceptable method of birth control for at least 1 month prior to dosing, with a negative urine pregnancy test result at screening and predose periods; and
  • Patient met American Society of Anesthesiologists (ASA) Physical Status Classification System of I to III.

Exclusion Criteria:

  • Patient had a history of allergic reaction or hypersensitivity to any anesthetic agent, narcotic, or benzodiazepine;
  • Patient did not meet nils per os (NPO) status per ASA Guideline or institution's guideline.
  • Patient had condition(s) that, in the opinion of the Investigator, could interfere with appropriate airway management;
  • Patient participated in an investigational drug study within 1 month prior to study start;
  • Patient had a history of mental or visual impairment that would not permit successful measurement of cognitive evaluations;
  • Patient was unwilling to adhere to pre- and postprocedural instructions; or
  • Patient for whom the use of fentanyl or midazolam was contraindicated.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
The primary efficacy hypothesis was that AQUAVAN could sedate (≥3 consecutive Modified OAA/S scores ≤4) patients AND that they could complete the procedure successfully without requiring alternative sedative medication AND without requiring manual or

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Change from baseline DSST score over time during recovery period
Patient's rating at 24 hour post discharge telephone survey
Secondary Efficacy Endpoints
Time to Fully Recovered from end of procedure
Time to Fully Alert from end of procedure
Duration and percent of time when a patient's Modified OAA/S score is at each level between the first dose of study medications and Fully Alert, inclusive

Time to sedation
Number of procedure interruptions due to inadequate sedation
Patient's rating of experience after Fully Recovered
