- Change from baseline in average daily sunlight exposure time (minutes) to first prodromal symptom (burning, tingling, itching, or stinging) associated with sunlight exposure between 1 hour post sunrise and 1 hour pre-sunset at Week 26. [ Time Frame: Baseline (Week 0) and 26 weeks ]
- Patient Global Impression of Change (PGIC). [ Time Frame: Week 26 ]PGIC: Scale from 1 to 7, where 7 is worse.
- Total number of sunlight-induced pain events with pain rating of 1-10 on the Likert scale during the 26-week double-blind treatment period. [ Time Frame: Baseline (Week 0) and Week 26 ]
- Change from baseline for total score in the domain of pain intensity in the PROMIS-57. [ Time Frame: Baseline (Week 0) and Week 26 ]Pain intensity: 0 to 10, where 10 is worst pain imaginable.
- The percentage of subjects who are responders based on average daily sunlight exposure time to first prodromal symptom associated with sunlight exposure between 1 hour post sunrise and 1 hour pre-sunset defined by within-subject meaningful change. [ Time Frame: Week 26 ]
- Change from baseline for total score in the domain of physical function in the PROMIS-57. [ Time Frame: Baseline (Week 0) and Week 26 ]Physical function: 1-5, where 5 is without any difficulty.
