Trial Outcomes & Findings for A Study to Evaluate Efficacy and Safety of VX-150 in Subjects With Acute Pain Following Bunionectomy (NCT NCT03206749)

NCT ID: NCT03206749

Last Updated: 2021-02-03

Results Overview

SPID was calculated as the sum of the product of time (in hours) elapsed since previous measurements and pain intensity difference. Pain intensity difference was calculated by subtracting the pain intensity score at given post-dose time points from the baseline pain intensity scores (using pain rating score range: 0 =no pain to 10 =worst possible pain). SPID24 was calculated from 0 to 24 hours and the score range was -240 (worst score) to 240 (best score).

PRIMARY outcome

Timeframe: 0 to 24 hours after the first dose

Population: Full Analysis Set (FAS) included all randomized participants who received at least 1 dose of study drug. As a standard-of-care reference arm, the "HB/APAP" arm was not intended for statistical comparisons to VX-150.

SPID was calculated as the sum of the product of time (in hours) elapsed since previous measurements and pain intensity difference. Pain intensity difference was calculated by subtracting the pain intensity score at given post-dose time points from the baseline pain intensity scores (using pain rating score range: 0 =no pain to 10 =worst possible pain). SPID24 was calculated from 0 to 24 hours and the score range was -240 (worst score) to 240 (best score).
