Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 16 |
WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis (OA). WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee or hip during past 48 hours. It is calculated as mean of the scores from 5 individual questions, each scored on a numerical rating scale (NRS) of 0 (no pain) to 10 (extreme pain), where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 (no pain) to 10 (extreme pain), where higher scores indicate higher pain. |

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale Score at Week 16 |
WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with OA. WOMAC physical function is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in index knee or hip during past 48 hours. It is calculated as mean of the scores from 17 individual questions, each scored on a NRS of 0 (no difficulty) to 10 (extreme difficulty), where higher scores indicate worse function. Total score range for WOMAC physical function subscale score is 0 (no difficulty) to 10 (extreme difficulty), where higher scores indicate worse function. Physical function refers to participant's ability to move around and perform usual activities of daily living. |

Change From Baseline in Patient Global Assessment (PGA) of Osteoarthritis Score at Week 16 |
Participants answered: "Considering all the ways your osteoarthritis in your index joint (knee/hip) affects you, how are you doing today?" Participants responded by using a 5-point Likert scale, where 1 = very good (asymptomatic 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 which are intolerable and inability to carry out all normal activities). Higher score indicated worst condition. |

Change From Baseline in Average Pain Score in the Index Knee or Hip at Weeks 1, 2, 3, 4, 6, 8, 10, 12, 16, 20, and 24 |
Participants were asked to assess index joint (knee/hip) pain during the past 24 hours on an 0-10 point integer scale ranging from 0 (no pain) to 10 (worst possible pain). Baseline score was calculated as the mean of the scores in the index joint over the 3 days days in the initial pain assessment period and a weekly mean was calculated using the daily pain scores in the index joint within each study week. The change from Baseline was calculated using the difference between each post-baseline weekly mean and the baseline mean score, where negative change indicated an improvement. |

SF-36v2 was a standardized survey evaluating 8 aspects of functional health and well-being: physical and social functioning, physical and role limitations due to emotional problems, bodily pain, general health, vitality, and mental health. The total score and the score for a section was an average of the individual question scores, which were scaled 0-100. Higher scores reflected better participant status and positive change indicated an improvement. |

Change From Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Physical and Mental Component Scores at Week 12 and 24 |
SF-36v2: standardized survey evaluating 8 aspects of functional health and wellbeing (physical and social functioning, role limitations due to physical and emotional problems, bodily pain, general health, vitality, mental health). Total score for each aspect were scaled 0-100. Higher scores reflect better participant status and positive change indicated an improvement. For obtaining physical and mental component scores, z-score for each scale=(observed score - mean score for general 1990 United States [US] population)/corresponding standard deviation. The 2 component scores were obtained by multiplying each aspect z-score by physical or mental factor score coefficient (1990 general US population) and summing the eight products. Component scores indicated how many standard deviations higher (in case of positive z-score [better functioning])/lower (in case of negative z-score [worse functioning]) participant's value was relative to the mean of the reference population. |

Change From Baseline in European Quality of Life - 5 Dimension (EQ-5D) Index Score at Week 24 |
EQ-5D was a standardized, participant-administered measure of health outcome. It provides a descriptive profile for 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), using 3 levels (no, moderate, or extreme dysfunction) and a single index value characterizing current health status using a visual analog scale with score ranging from 0 (worst) to 100 (best). EQ-5D summary index was obtained with a formula that weights each level of the dimensions. The index-based score was interpreted along a continuum of 0 (death) to 1 (perfect health). Negative change from baseline represented worsening. |

Baseline EQ-5D individual health state profile was determined as number of participants "no dysfunction, moderate or some dysfunction and extreme dysfunction" and change from baseline in EQ-5D individual health state profile was determined as number of participants "improved, no change or worsened". |
