The primary objective of this study is to evaluate the analgesic efficacy of DMTS, compared with placebo, in subjects following abdominoplasty.

Study Overview

Status

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, double-blind, placebo-controlled, one-time application study of DMTS or matching placebo over a 4-day treatment period (Day 1 Time 0 occurs when the DMTS or matching placebo systems have been applied). Subjects scheduled for an abdominoplasty will be screened up to 28 days prior to surgery. Eligible subjects will be randomized equally to treatment with DMTS or matching placebo. An independent safety monitoring committee will periodically review unblinded safety data to confirm the safety/tolerability of the dose or recommend a dose reduction.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female, ≥ 18 years of age.
  • Scheduled to undergo a full abdominoplasty (including repair of small incidental abdominal hernias, but not including liposuction).
  • Have a physical status classification of 1 or 2 per the American Society of Anesthesiology.
  • Have a body weight > 58 kg, and body mass index of 20 to 38 kg/m2, inclusive.

Exclusion Criteria:

  • Known sensitivity to dexmedetomidine or any excipient in the DMTS/placebo or to any peri- or postoperative medication whose use is required in this study.

  • History of deep vein thrombosis or factor V Leiden deficiency.
  • History of syncope or other syncopal attacks.
  • Present and/or significant history of postural hypotension (determined through examination by the investigator or designee), or history of severe dizziness or fainting on standing in the opinion of the investigator.
  • Evidence of a clinically significant 12-lead ECG abnormality.

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
Measure Description
Time Frame
Time-interval weighted summed pain intensity (SPI) at designated time points
Time Frame: 5 to 96 hours following surgery
The SPI measured using the 11-point (0 to 10) numeric rating scale, where 0 is equal to no pain and 10 is equal to worst pain
5 to 96 hours following surgery

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
Measure Description
Time Frame
Time-interval weighted summed pain intensity (SPI) over various time intervals
Time Frame: 5 to 96 hours following surgery
The SPI measured using the 11-point (0 to 10) numeric rating scale, where 0 is equal to no pain and 10 is equal to worst pain, measured at rest over various time intervals
5 to 96 hours following surgery
Rescue Medication
Time Frame: Up to 96 hours post surgery
The proportion of subjects using rescue analgesic medication
Up to 96 hours post surgery
Rescue Medication units
Time Frame: Up to 96 hours post surgery
Total dose of rescue analgesic medication (in morphine-equivalent units)
Up to 96 hours post surgery
Integrated Pain score and Rescue Medication
Time Frame: Up to 96 hours post surgery
Integrated assessment of summed pain intensity (SPI) using the 11-point (0 to 10) numeric rating scale, where 0 is equal to no pain and 10 is equal to worst pain, at the time Rescue Medication was administered
