The 24-question WOMAC Osteoarthritis Index assesses osteoarthritis (OA) symptoms using pain (5 questions), stiffness (2 questions) and physical function (17 questions) subscales. The WOMAC pain subscale was calculated for each participant at each time point for analysis as the mean score (range 0-100 millimeter [mm] VAS; 0=very good and 100=very poor) of all 5 questions related to pain. Bayesian posterior adjusted mean was calculated using a Bayesian Normal Dynamic Linear Model (NDLM) dose response model with baseline and pooled investigator site included as baseline covariates.

Full Analysis Set (FAS) is the number of randomized participants who received at least 1 dose of study drug and had at least 1 post-dose baseline efficacy assessment. N = participants in the full analysis set with an evaluable WOMAC assessment at weeks 2, 4, 6 or 8. The 95% Crl (Credible Interval) is reported, not confidence interval (CI).

The 24-question WOMAC Osteoarthritis Index assesses osteoarthritis symptoms using pain (5 questions), stiffness (2 questions) and physical function (17 questions) subscales. The WOMAC Osteoarthritis Index version 3.1 was administered according to the study schedule. The WOMAC physical function subscale was calculated for each participant at each time point for analysis as the mean score (range 0-100 mm VAS; 0=very good and 100=very poor) of all 17 questions related to physical function. Least Square Mean (LSM) was calculated using a mixed-effects model repeated measures (MMRM) approach with treatment, visit and the interaction of treatment and visit were fitted as fixed effects in the model and baseline and pooled investigator site as baseline covariates.

FAS: Randomized participants who received at least 1 dose of study drug and had at least 1 post-dose baseline efficacy assessment. N = participants in the full analysis set with an evaluable WOMAC assessment at weeks 2, 4, 6 or 8.

The PGA is a patient-rated instrument that measures their assessment of overall OA symptoms. It is based on the participant's response to the question "Considering all the ways your osteoarthritis affects you, how are you doing today?" using a 100 mm VAS (0=very good and 100=very poor). LSM mean was calculated using a mixed-effects model repeated measures (MMRM) approach with treatment, visit and the interaction of treatment and visit were fitted as fixed effects in the model and baseline and pooled investigator site as baseline covariates.

FAS: Randomized participants who received at least 1 dose of study drug and had at least 1 post-dose baseline efficacy assessment. N = participants in the full analysis set with an evaluable PGA assessment at weeks 2, 4, 6 or 8.

The responders according to OMERACT-OARSI criteria: participants with at least 50 % improvement in pain or in function scores, along with absolute improvement of 20 mm, were considered responders. Alternatively, participants were considered responders if they showed at least 20% improvement and absolute improvement of 10 mm in at least two of the following scores: pain, function and Patients Global Assessment (PGA) scores.

FAS: Randomized participants who received at least 1 dose of study drug and had at least one post-dose efficacy assessment. N= participants analyzed in the full analysis set with an evaluable response rate at week 8.

The 24-question WOMAC Osteoarthritis Index assesses osteoarthritis symptoms using pain (5 questions), stiffness (2 questions) and physical function (17 questions) subscales. The WOMAC stiffness subscale will be calculated for each participant at each time point for analysis as the mean score (range 0-100 mm VAS; 0=very good and 100=very poor) of 2 questions related to stiffness. LSM mean was calculated using a mixed-effects model repeated measures (MMRM) approach with treatment, visit and the interaction of treatment and visit were fitted as fixed effects in the model and baseline and pooled investigator site as baseline covariates.

The 24-question WOMAC Osteoarthritis Index assesses osteoarthritis symptoms using pain (5 questions), stiffness (2 questions) and physical function (17 questions) subscales.The WOMAC total score was calculated for each participant at each time point for analysis as the mean score (range 0-100 mm VAS; 0=very good and 100=very poor) of 24 questions. LSM mean was calculated using a mixed-effects model repeated measures (MMRM) approach with treatment, visit and the interaction of treatment and visit were fitted as fixed effects in the model and baseline and pooled investigator site as baseline covariates.
