Outcome Measures
Primary Outcomes (16)
Change From Baseline to Study Endpoint in Mean Weekly Pain Scores
Change from baseline: Score at study endpoint minus score at baseline. Study endpoint is defined as the mean of the last seven entries of the daily pain diary using the 11-point numerical rating scale 0(no pain) to 10(worst possible pain) while on study medication up to and including day after last dose.
From baseline to Week 13 or up to study discontinuation (Study Endpoint)
Change From Baseline to Study Endpoint in Mean Weekly Pain Scores by Groups of Subjects With Expected Similar Plasma Concentrations
Change from baseline: Score at study endpoint minus score at baseline. Study endpoint is defined as the mean of the last seven entries of the daily pain diary using the 11-point numerical rating scale 0(no pain) to 10(worst possible pain) while on study medication up to and including day after last dose. Subjects are classified by exposure to pregabalin, which is estimated by creatinine clearance (CLcr).
From baseline to Week 13 or up to study discontinuation (Study Endpoint)
Number of Responders
A responder is defined as a subject with a 50% reduction in weekly mean pain score from baseline to study endpoint.
From baseline to Week 13 or up to study discontinuation (Study Endpoint)
