  1. Time-weighted Sum of Pain Intensity Difference (SPID) as Recorded on the Numeric Pain Rating Scale (NPRS) From 0 to 48 Hours (SPID48)

    Timeframe: From 0 to 48 Hours After the First Dose of Study Drug

  1. Proportion of Participants With Greater Than or Equal To (>=) 30 Percent (%) Reduction in NPRS at 48 Hours

    Timeframe: At 48 Hours After the First Dose of Study Drug

  2. Proportion of Participants With >=50% Reduction in NPRS at 48 Hours

    Timeframe: At 48 Hours After the First Dose of Study Drug

  3. Proportion of Participants With >=70% Reduction in NPRS at 48 Hours

    Timeframe: At 48 Hours After the First Dose of Study Drug

  4. Maximum Observed Plasma Concentration (Cmax) of VX-993 and its Metabolite

    Timeframe: Pre-dose to 12 Hours and 24 to 36 Hours After the First Dose of Study Drug

  5. Area Under the Concentration Versus Time Curve During a Dosing Interval (AUCtau) of VX-993 and its Metabolite

    Timeframe: Pre-dose to 12 Hours and 24 to 36 Hours After the First Dose of Study Drug

  6. Time to Reach Maximum Observed Plasma Concentration (Tmax) of VX-993 and its Metabolite

    Timeframe: Pre-dose to 12 Hours and 24 to 36 Hours After the First Dose of Study Drug

  7. Safety and Tolerability as Assessed by Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Timeframe: Day 1 up to Day 19
