Outcome Measures
Primary Outcomes (1)
Time-weighted Sum of the Pain Intensity Difference as Recorded on Numeric Pain Rating Scale (NPRS) 0 to 24 Hours (SPID24) 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).
0 to 24 Hours After First Dose
Secondary Outcomes (9)
Time-weighted Sum of Pain Intensity Difference as Recorded on NPRS 0 to 48 Hours (SPID48) After First Dose
0 to 48 Hours After First Dose
Proportion of Participants With at Least 30 Percent (%) Reduction in NPRS at 24 Hours After First Dose of VX-150 Versus Placebo
From Baseline at 24 Hours After First Dose
Proportion of Participants With at Least 50% Reduction in NPRS at 24 Hours After the First Dose of VX-150 Versus Placebo
From Baseline at 24 Hours After First Dose
Proportion of Participants With at Least 70% Reduction in NPRS at 24 Hours After the First Dose of VX-150 Versus Placebo
From Baseline at 24 Hours After First Dose
Time to Onset of Confirmed Perceptible Pain Relief After First Dose of VX-150 Versus Placebo
Up to 6 hours After the First Dose

You may qualify if:
- Before surgery:
- Body mass index (BMI) of 18.0 to 38.0 kilogram per meter square (kg/m\^2)
- Be scheduled to undergo a primary unilateral first metatarsal bunionectomy repair, without collateral procedures, under regional anesthesia (Mayo and popliteal sciatic block) not to include base wedge procedure
- After surgery:
- Subject reported pain of greater than or equal to (\>=) 4 on Numeric Pain Rating Scale (NPRS) and moderate or severe pain on the Verbal Categorical Rating Scale (VRS) within 9 hours after removal of the popliteal sciatic block on Day 1
- Subject is lucid and able to follow commands
- All analgesic guidelines were followed during and after the bunionectomy
You may not qualify if:
- Before surgery:
- History in the past 10 years of malignancy, except for squamous cell skin cancer, basal cell skin cancer, and Stage 0 cervical carcinoma in situ
- History of cardiac dysrhythmias requiring anti-arrhythmia treatment(s)
- History of abnormal laboratory results \>=2.5\*upper limit of normal (ULN)
- History of peripheral neuropathy
- A known or clinically suspected infection with human immunodeficiency virus or hepatitis B or C viruses
- Prior medical history of bunionectomy or other foot surgery on the index foot
- History of peptic ulcer disease, or intolerance or unwillingness to receive ibuprofen
- After surgery:
- Subject had a type 3 deformity requiring a base wedge osteotomy or concomitant surgery
