    WOMAC: self-administered, disease-specific 24-item questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis of index joint (knee or hip). The WOMAC pain subscale was a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis of index joint (knee or hip) during past 48 hours. It was calculated as mean of the scores from 5 individual questions scored on a numerical rating scale (NRS) of 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain. Total score range for WOMAC pain subscale score was 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain.

  27. Change From Baseline in Percent Work Time Missed Due to Osteoarthritis at Week 24 Assessed Using Work Productivity and Activity Impairment Questionnaire- Specific Health Problem (WPAI-SHP): Baseline Observation Carried Forward (BOCF) [ Time Frame: Baseline, Week 24 ]
    The WPAI assesses work productivity and impairment. It is a 6-item questionnaire used to assess the degree to which a specified health problem affected work productivity and regular activities over the past 7 days. The questions (Q) are: Q1 = currently employed. Q2 = hours missed due to health problems. Q3 = hours missed other reasons. Q4 = hours actually worked. Q5 = degree health affected productivity while working (0-10 scale). Q6 = degree health affected regular activities (0-10 scale). Subscale scores are calculated: Percent work time missed due to health problem: Q2/(Q2+Q4). The computed percentage range for each sub-scale is 0-100, where higher numbers indicate greater impairment and less productivity.

    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Week 64 that were absent before treatment or that worsened relative to pre-treatment state.

  41. Change From Baseline in Neuropathy Impairment Score (NIS) at Weeks 2, 4, 8, 12, 16, 24, 32, 40, 48 and 56: Observed Data [ Time Frame: Baseline, Weeks 2, 4, 8, 12, 16, 24, 32, 40, 48, and 56 ]
    The Neuropathy Impairment Score is the sum of scores over all 37 items from both the left and right side. The neurological impairment score assessed strength of groups of muscles of the head and neck, upper limbs and lower limbs, deep tendon reflexes and sensation (tactile, vibration, joint position sense, and pin prick) of index fingers and great toes through neurological examination. NIS calculated scoring muscle weakness (0=normal, 1=25% weak, 2=50% weak, 3=75% week, 3.25= move against gravity, 3.5=movement gravity eliminated, 3.75= muscle flicker no movement, 4=paralysis), scoring reflexes (0=normal, 1=reduced. 2=absent), scoring sensation (0=normal, 1=decreased, 2=absent). For NIS possible overall score (combined of both left and right sides of each domain), ranged from 0 (no impairment) to 244 (maximum impairment), higher scores indicated increased/more neuropathic deficits.

    Human serum ADA samples were analyzed for the presence or absence of anti--tanezumab antibodies by using a semi quantitative enzyme -linked immunosorbent assay (ELISA). Participants tested positive for ADA response on at least one post-baseline visit were reported. Participants with ADA titer level >=4.32 for tanezumab were considered ADA positive.

  2. Number of Participants With Positive Urine or Serum Pregnancy Test [ Time Frame: Baseline up to Week 56 ]
    Female participants, who reported positive in urine or serum pregnancy test were reported.
