Outcome Measures
Primary Outcomes (1)
Change From Baseline in Weekly Average of Average Daily Knee Pain Intensity Using Numeric Rating Scale at Week 12
Change from Baseline in knee pain due to Osteoarthritis were reported by weekly average of average daily pain numeric rating scale (NRS) at Week 12. The pain NRS is an 11-point scale (ranging from 0-10) for self-reporting of average daily knee pain where 0 indicates no pain, and 10 indicates the worst possible pain. For each participant, the weekly average of average daily pain score was calculated using the mean value of available daily pain scores falling in the assessment window for each week. A negative change from baseline indicates an improvement in pain. Participants were asked to complete the pain NRS questionnaire at the same time in the evening each day. Baseline scores were assigned based on an average of 7 days prior to day 1 dosing visit. Posterior mean change from baseline, 95 percent (%) credible interval (CI) was derived using Bayesian mixed model repeated measures. The data presented are the posterior mean with 95% confidence interval refers to 95% credible interval.

- Alanine transaminase (ALT) \>1.5 times upper limit of normal (ULN).
- Bilirubin \>1.5 times ULN (isolated bilirubin \>1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin \< 35 percent (%)
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
- Evidence of renal insufficiency, indicated by estimated creatinine clearance \< 60 milliliter/ minute (mL/min)/1.73 square meter (m\^2) at screening.
- Sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates participation in the study.
