Difference in mean change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale score using an 11-point (0-10) numeric rating scale (NRS) between RTX-GRT7039 and placebo. The WOMAC pain subscale consists of 5 questions using an 11-point numeric rating scale (NRS, from 0 = no pain to 10 = pain as bad as you can imagine). The scores are averaged over the number of questions.
