Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adjudicated Primary Composite Joint Safety Outcome | 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. | Baseline up to Week 80 | 
| Observation Time-Adjusted Event Rate of Participants With Adjudicated Primary Composite Joint Safety Outcome | 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. | Baseline up to Week 80 | 
| Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale 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. 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. | Baseline, Week 16 | 
| Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale 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. 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. | Baseline, Week 16 | 
| Change From Baseline in Patient's Global Assessment (PGA) of Osteoarthritis at Week 16 | 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. | Baseline, Week 16 |

ECG abnormalities included: 1) QT interval, QT interval corrected using Bazett's formula (QTcB) and QT interval corrected using Fridericia's formula (QTcF): increase from baseline greater than (>) 30 millisecond (ms) or 60 ms; absolute value > 450 ms, >480 ms and > 500 ms; 2) heart rate (HR) : absolute value <=50 bpm and decrease from baseline >=20 bpm; absolute value >=120 beats per minute (bpm) and increase from baseline >=20 bpm; 3) PR interval: absolute value >=220 ms and increase from baseline >=20 ms; 4) QRS interval: absolute value >= 120 ms. | Baseline, Weeks 56 and 80 | 
| Change From Baseline in Heart Rate (as Assessed by ECG) at Weeks 56 and 80 | Heart rate was measured at sitting position. | Baseline, Weeks 56 and 80 | 
| Number of Participants With Confirmed Orthostatic Hypotension | Orthostatic hypotension was defined as postural change (supine to standing) that met the following criteria: For systolic BP <=150 mmHg (mean supine): Reduction in systolic BP>=20 mmHg or reduction in diastolic BP>=10 mmHg at the 1 and/or 3 minute standing BP measurements. For systolic BP >150 mmHg (mean supine): Reduction in systolic BP>=30 mmHg or reduction in diastolic BP>=15 mmHg at the 1 and/or 3 minute standing BP measurements. If the 1 minute or 3 minute standing BP in a sequence met the orthostatic hypotension criteria, then that sequence was considered positive. If 2 of 2 or 2 of 3 sequences were positive, then orthostatic hypotension was considered confirmed. | Baseline, Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80 | 
| Change From Baseline in Survey of Autonomic Symptom (SAS) Scores at Weeks 24, 56 and 80 | The SAS is a 12 item (11 for females) questionnaire, from which the total number of symptoms (0-12 for males and 0-11 for females) is calculated. Each positive symptom is rated from 1 (not at all) to 5 (a lot). The total impact score was the sum of all symptom rating scores, with 0 assigned where the participant did not have the particular symptom. The range for the total impact score is 0-60 for males and 0-55 for females, higher scores indicating higher impact. | Baseline, Weeks 24, 56 and 80 | 
| Change From Baseline in Neuropathy Impairment Score (NIS) at Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80 | NIS is a standardized instrument used to evaluate participant for signs of peripheral neuropathy. NIS is the sum of scores of 37 items, from both the left and right side, where 24 items scored from 0 (normal) to 4 (paralysis), higher score indicated higher abnormality/impairment and 13 items scored from 0 (normal), 1 (decreased) and 2 (absent), higher score indicated higher impairment. NIS possible overall score ranged from 0 (no impairment) to 244 (maximum impairment), higher scores indicated increased impairment. | Baseline, Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80 | 
| Number of Participants With Anti-Tanezumab Antibodies | Human serum anti-drug antibody (ADA) samples were analyzed for the presence or absence of anti-tanezumab antibodies by using a semi quantitative enzyme linked immunosorbent assay (ELISA). | Baseline, Weeks 8, 16, 32, 48, 56, 64 and 80 |
