Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale at Week 24
Baseline, Week 24

WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis (OA). The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to OA of index joint (knee or hip) during past 48 hours. It was calculated as the mean of scores from 5 individual questions scored on a numerical rating scale (NRS). Scores for each question and WOMAC Pain subscale score on NRS ranged from 0 (no pain) to 10 (extreme pain), where higher scores indicated higher pain.

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale at Week 24
Baseline, Week 24

WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with OA. Physical function refers to participant's ability to move around and perform usual activities of daily living. The WOMAC physical function subscale is a 17-item questionnaire used to assess the degree of difficulty experienced due to OA in index joint (knee or hip) during past 48 hours. It was calculated as mean of the scores from 17 individual questions scored on a NRS. Scores for each question and WOMAC physical function subscale score on NRS ranged from 0 (no difficulty) to 10 (extreme difficulty), where higher scores indicated extreme difficulty/worse physical function.

Participants responded on a scale ranging from 1-5, where 1=very good (no symptom and no limitation of normal activities), 2= good (mild symptoms and no limitation of normal activities), 3= fair (moderate symptoms and limitation of some normal activities), 4= poor (severe symptoms and inability to carry out most normal activities), and 5= very poor (very severe symptoms and inability to carry out all normal activities). Higher scores indicated worsening of condition.

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Version 3.1 (WOMAC 3.1) Subscales Scores at Week 1
Baseline, Week 1 (Part 1 and 2)

WOMAC 3.1: participant assessed questionnaire consists of 24 questions divided into 3 domains; pain (5 questions), stiffness (2 questions), function (17 questions). Functional domain provided information of ability to perform activities of daily living. The participant performed test directly on electronic diary, using validated electronic VAS ranging from 0 to 100 (0 = none to 100 = extreme). Each domain scored by averaging VAS scores of component questions. Total subscale score for each of the 3 domains range from: 0 to 100, lower score indicated better daily living.

Change From Baseline in Daily Average Low Back Pain Intensity (LBPI) Score at Week 6
Baseline, Week 6

Daily average low back pain was assessed on an 11-point numeric rating scale (NRS). Participants described their average low back pain during the past 24 hours on a scale ranging from 0 (no pain) to 10 (worst possible pain). Baseline value was calculated as mean of the scores over 5-day prior to randomization (initial pain assessment period). Post-baseline weekly scores were calculated based on the mean of the scores over the 7 days prior to and including the day at the end of the corresponding week.
