Evaluation of the Dexmedetomidine Transdermal Systems for Postoperative Analgesia Following Abdominoplasty

Phase 2
Conditions
Pain, Postoperative
Interventions
Drug: DMTS Patch
Drug: Placebo Patch
Registration Number
NCT05412992
Lead Sponsor
Teikoku Pharma USA, Inc.
Brief Summary

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

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.

Primary Outcome Measures
NameTimeMethod
Time-interval weighted summed pain intensity (SPI) at designated time points5 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

Secondary Outcome Measures
NameTimeMethod
Time-interval weighted summed pain intensity (SPI) over various time intervals5 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

Rescue MedicationUp to 96 hours post surgery

The proportion of subjects using rescue analgesic medication

Rescue Medication unitsUp to 96 hours post surgery

Total dose of rescue analgesic medication (in morphine-equivalent units)

Integrated Pain score and Rescue MedicationUp 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
