Outcome Measures
Primary Outcomes (1)
Change From Baseline in WOMAC Pain at Week 12 for TLC599 12 mg Versus Placebo
The WOMAC (Western Ontario \& McMaster Universities Osteoarthritis Index, Version 3.1) consists of 24 questions rated on a 0-4 Likert scale, totaling a score from 0-96, reflecting the previous 24 hours. Sub-scale scores for Pain (5 items, a 0-20 scale), Stiffness (2 items, a 0-8 scale), and Physical Function (17 items, a 0-68 scale) are summed to calculate the WOMAC Composite score. Both composite and sub-scale scores are normalized to a 0-4 scale for analysis, with higher scores indicating greater severity.
