Study Endpoints
Primary Endpoints
Time-weighted Sum of the Pain Intensity Difference as Recorded on Numeric Pain Rating Scale (NPRS) 0 to 24 Hours (SPID24) After First Dose
0 to 24 Hours After First Dose

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).

Time-weighted Sum of the Pain Intensity Difference (SPID) Between VX-150 Versus Placebo as Recorded on a Numeric Pain Rating Scale (NPRS) 0 to 24 Hours After the First Dose
0 to 24 hours after the first dose

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).
