SECONDARY outcome

Timeframe: Baseline, Second Visit (Week ≥ 2), Final Visit (Week 4)

Population: Intent to treat (ITT) population: a subset of the safety population who underwent Baseline assessment, received study drug for at least 2 weeks, and had at least 1 follow-up visit. N = number of subjects with a Visual Analog Scale (VAS) pain score at Baseline Visit.

Change from Baseline in 10 cm VAS pain score; 10-point pain intensity ordinal rating system: 0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, 7-9 = severe pain, 10 = worst possible pain. Change = scores at second visit and final visit minus score at Baseline.

SECONDARY outcome

Timeframe: Second Visit (Week ≥ 2), Final Visit (Week 4)

Population: Intent to treat (ITT) population: a subset of the safety population who underwent Baseline assessment, received study drug for at least 2 weeks, and had at least 1 follow-up visit. N=number of subjects in ITT population.

Patient's Clinical Global Impression of treatment satisfaction. Treatment satisfaction item of CGI has a scale of five discrete points: excellent, very good, good, fair and poor. Shift table shows the number of subjects with each score point rating at the Final Visit by the number of subjects with each score point rating at the Second Visit.
