Trial Outcomes & Findings for Phase 3, Sciatic Nerve Block With EXPAREL for Subjects Undergoing Bunionectomy (NCT NCT05157841)

NCT ID: NCT05157841

Last Updated: 2025-06-26

Results Overview

The numeric rating scale pain intensity scores ranging from 0 to 10, where 0 equals no pain and 10 equals the worst possible pain, from 0 to 96 hours post-surgery. For each subject, the area under the curve was derived using the trapezoidal rule on the pain scores adjusted for opioid pain medication using the observed and imputed values. Area under the curve started with the first pain assessment obtained after surgery and use all subsequent pain assessments up to 96 hours post-surgery. Pain scores were taken at 5 interval point 0 hours, 24 hours, 48 hours, 72 hours, and 96 hours. There were also unscheduled pain scores measured before opioid consumption also included in the area under the curve calculation. The area under the curve ranged from 0 to 960. Higher scores represent a worse outcome.

Participant Flow

Participants were recruited based on physician referral at 6 sites between February 2022 and April 2022 for Part A and between April 2022 and July 2022 for Part B. The first participant was enrolled on February 15, 2022 and the last participant was enrolled on July 18, 2022.

Of 452 screened participants, 185 met inclusion criteria and were randomized to treatment in Part A (66 participants) or Part B (119 participants). Overall results are presented per treatment arm

PRIMARY outcome

Timeframe: 0- 96 hours post-surgery

Population: The analysis was performed on the efficacy analysis set which included all participants in the safety analysis set who underwent the planned surgery and had at least one post-drug administration NRS pain assessment.

The numeric rating scale pain intensity scores ranging from 0 to 10, where 0 equals no pain and 10 equals the worst possible pain, from 0 to 96 hours post-surgery. For each subject, the area under the curve was derived using the trapezoidal rule on the pain scores adjusted for opioid pain medication using the observed and imputed values. Area under the curve started with the first pain assessment obtained after surgery and use all subsequent pain assessments up to 96 hours post-surgery. Pain scores were taken at 5 interval point 0 hours, 24 hours, 48 hours, 72 hours, and 96 hours. There were also unscheduled pain scores measured before opioid consumption also included in the area under the curve calculation. The area under the curve ranged from 0 to 960. Higher scores represent a worse outcome.
