Primary Outcome Measures :
  1. Change From Baseline in Daily Average Pain Intensity Numeric Rating Scale (NRS) Score at Week 6 [ Time Frame: Baseline, Week 6 ]
    Daily average pain was assessed on an 11-point NRS over the past 24 hours (before each specified visit), where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine". Lower the score, lesser the pain intensity.


Secondary Outcome Measures :

Results were summarized for opioid dose adjust period, baseline assessment period and post-baseline period.

  11. Number of Doses of Rescue Medication Required Per Week [ Time Frame: Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 ]
    Participants received immediate release (IR) opioid as rescue medication as needed for breakthrough pain from Day 1-113 at the dose determined during the pre-treatment phase, provided the average total daily dose of opioids between study visits does not exceed the baseline total daily opioid dose by more than 10%.

  12. Change From Baseline in Opioid-Related Symptom Distress Scale (OR-SDS) at Weeks 2, 4, 6, 12, and 16 [ Time Frame: Baseline, Week 2, 4, 6, 12, 16 ]
    OR-SDS: participant-rated levels of frequency (F), severity (S), degree of bother (DoB) for 10 symptoms: fatigue, drowsiness, concentration, confusion, nausea, dizziness, constipation, itching, difficulty with urination, retching/vomiting.

Mean of F, S and DoB was calculated for each symptom to derive composite scores/multi-domain average (MDA) scores which ranges from 0 to 4.33. Higher MDA=worse symptom. Composite scores for frequency (FCS), severity (SCS), degree of bother, and MDA were calculated as mean of these scores across 10 symptoms and had same ranges as individual scores frequency (0 to 4:'did not have' to 'almost constantly'), severity (0 to 4:'did not have' to 'very severe'), degree of bother (0 to 5:'did not have' to 'very much'); higher scores=more distress

    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 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 113 days that were absent before treatment or that worsened relative to pretreatment state.

  21. Number of Participants With Physical Examination Abnormalities [ Time Frame: Baseline up to Week 16 or Early Termination (up to 113 days) ]
    Physical examinations included general appearance (skin, neck, eyes, ears, nose, throat), cardiovascular system (including rhythm and presence of other cardiac abnormalities, such as gallops, murmurs, and cardiomegaly), respiratory system, gastrointestinal system, genitourinary system, musculoskeletal system, and any additional assessments necessary to establish baseline status or evaluate symptoms or adverse experiences. Abnormalities in physical examination was based on investigator's discretion.

  22. Number of Participants With Abnormal Neurological Examination [ Time Frame: Week 2, 4, 6, 12, 16, Early Termination (up to 113 days) ]
    Neurological examinations 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 finger and great toes in order to complete the neuropathy impairment score (NIS). 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) for muscle strength, higher score indicated higher abnormality/impairment, and 13 items scored from 0 (normal), 1 (decreased) and 2 (absent) for sensation, higher score indicated higher impairment. NIS possible overall score ranged from 0 (no impairment) to 244 (maximum impairment), higher scores indicated increased impairment.

  23. Vital Sign Examination: Body Temperature [ Time Frame: Baseline (Day 1 0H), Week 2, 4, 6, 12, 16, Early Termination (up to 113 days) ]

    Systolic BP: the measurement of the pressure when the heart is contracted (systole). The systolic pressure indicates the maximum amount of work/force the heart has to perform with each stroke in order to move blood through the arteries. Diastolic BP: the pressure in the large arteries during the relaxation of the left ventricle. The diastolic pressure indicates the amount of pressure the heart must overcome in order to generate the next beat.

    Human serum samples were analyzed using electrochemiluminescent (ECL) immunoassay for the presence of anti-tanezumab antibodies. Same participant may have positive (titer value >=4.32) anti-tanezumab antibodies result at more than 1 time point.

  30. Electrocardiogram Examination [ Time Frame: Baseline (Pre-dose and 1 hour Post-dose), Week 4, 16, Early Termination (up to 113 days) ]
    ECG intervals included: RR (the time interval between consecutive heart beats), PR (time between the onset of atrial depolarization and the onset of ventricular depolarization), QRS (represented ventricular depolarization) and QT (time corresponding to the beginning of depolarization to repolarization of the ventricles), QTcF (QT interval corrected using Fridericia's formula [FF]), QTcB interval (QT interval corrected using Bazett's formula [BF]).

  31. Electrocardiogram Examination: Heart Rate [ Time Frame: Baseline (Pre-dose and 1 hour Post-dose), Week 4, 16, Early Termination (up to 113 days) ]
    Standard 12-lead ECG performed after participant had rested quietly for at least 10 minutes in a supine position was measured. The time interval between consecutive heart beats [RR interval] (in beats per minute [bpm]) was used to calculate heart rate.
