A Study Of Tanezumab as Add-On Therapy to Opioid Medication In Patients With Pain Due To Cancer That Has Spread To Bone

Change From Baseline in Brief Pain Inventory-Short Form (BPI-sf) Average Pain Scores at Week 1, 2, 4, 6, 8, 12 and 16: LOCF

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) to 10 (Pain as bad as you can imagine), lower score indicates lesser pain intensity. Question 5: 7 item subsets that measured level of interference of pain on daily functions on 11-point numeric rating scale 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.

Time frame: Opioid Dose Adjust Period (Day-30 to Day-4), Baseline Assessment period (Day-3 to Day-1), Post Baseline Period (Day 1 to Week 16)

Number of Doses of Rescue Medication Required Per Week

Change From Baseline in Opioid-Related Symptom Distress Scale (OR-SDS) at Weeks 2, 4, 6, 12, and 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. 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

Number of Participants With Abnormal Neurological Examination

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.
