NSAID

Any participant with incidence of an adjudicated outcome of primary osteonecrosis, rapidly progressive osteoarthritis (OA) type 1 or type 2, subchondral insufficiency fracture, or pathological fracture. Rapidly progressive OA type 1 events were those that the Adjudication Committee considered to have significant loss of joint space width (JSW) (greater than or equal to \[\>=\] 2 millimeters \[mm\]) within approximately 1 year without gross structural failure. Rapidly progressive OA type 2 events were those considered to have abnormal loss/destruction of bone including limited or total collapse of at least one subchondral surface (e.g., medial femoral condyle) that is not normally present in conventional end-stage OA.

Observation time was defined as the start day of first SC study medication until either the (i) date of completion of or withdrawal from study, if a participant did not have the event, or (ii) date of the event (earliest event within each participant in the case of multiple events). Primary joint safety outcome included participants with adjudicated outcome of primary osteonecrosis, rapidly progressive OA type 1 or type 2, subchondral insufficiency fracture, or pathological fracture. Event rate was calculated as the number of events per 1000 participant-years at risk.

WOMAC: Self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with 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, which may not be a whole (integer) number, 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.

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, which may not be a whole (integer) number, 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.

PGA of OA was assessed by asking a question from participants: "Considering all the ways your OA in your knee or hip (index joint) affects you, how are you doing today?" Participants responded on a scale ranging from 1-5, using Interactive Response Technology (IRT), 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.
