The worst pain was assessed an 11-point NRS over the past 24 hours 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 pain intensity.

The worst pain was assessed on 11-point NRS over the past 24 hours where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine". The lower the value the lesser pain intensity.

BPI-sf: self-administered questionnaire developed to assess severity, impact of pain on daily functions, consisted of 5 questions. Questions 1-4 measured magnitude of pain at its worst, least, average, right now. BPI-sf average pain measured the severity of pain based on the average pain experienced over the past 24-hours and ranged from 0 (No Pain) to10 (Pain as bad as you can imagine), lower scores indicates lesser pain intensity. Question 5: 7 item subsets that measured level of interference of pain on daily functions on 11-point NRS at 0 (Does not interfere) to 10 (Completely interferes).

The average daily opioid consumption was calculated as the daily sum of total opioid dosage in milligrams. Opioid consumption on each day was converted to the morphine equivalent dosage (MED). Results were summarized for opioid dose adjust period, baseline assessment period and post-baseline period.

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%.

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. For each symptom levels of F, S and DoB scored as: 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'). 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

Participant-rated 11 point Likert rating scale ranging from 0 (does not interfere) to 10 (completely interferes) assessed interference of pain in functional activities (general activity, walking ability, and normal work) in past 24 hours. Measures were scored by individual item as well as function composite score (calculated by taking mean of individual interference scores), both (individual scores and composite scores) ranging from 0 to 10 with lower scores being indicative of less pain interference.

The Patient's Global Evaluation of Study Medication (PGESM) was a single item that assessed the participant's perception of his/her response to the study medication. It was a self-administered question that utilizes a 4-point Likert scale from 1="Poor" to 4="Excellent", where higher score represented better outcome.

The Patient's Global Assessment of Cancer Pain was a global evaluation that utilized a 5-point Likert scale with a score of 1 being the best (Very Good) and a score of 5 being the worst (Very Poor), where higher score represented more pain.

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.

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.

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.

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.

Respiration rate measured as number of breaths taken per minute.

Heart rate is the number of heart beats per minute.

Criteria for laboratory tests abnormalities included: hemoglobin, hematocrit (\<0.8\*lower limit of normal \[LLN\]); red blood cell count (\<0.8\*LLN); platelets (\<0.5\*LLN or \>1.75\* upper limit of normal \[ULN\]); leucocytes (\<0.6\*LLN or \>1.5\*ULN); lymphocytes, total neutrophils (\<0.8\*LLN or \>1.2\*ULN); basophils, eosinophils, monocytes (\>1.2\*ULN); total bilirubin (\>1.5\* ULN); aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase (\>3\*ULN); creatinine, blood urea nitrogen (\>1.3\*ULN); glucose (\<0.6\*LLN or \>1.5\*ULN); uric acid (\>1.2\*ULN); sodium (\<0.95\*LLN or 1.05\*ULN); potassium, calcium, chloride, bicarbonate (\<0.9\*LLN or 1.1\*ULN); albumin, total protein (\<0.8\*LLN or 1.2\*ULN); urine analysis. Total number of participants without regards to baseline abnormality was summarized.

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.

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 \[BF\]).

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.
