A Phase 3 Study of Tanezumab for Chronic Low Back Pain

The RMDQ is a self-administered, widely used health status measure index of how well participants with low back pain (LBP) are able to function with regard to daily activities. It measures pain and function, using 24 items describing limitations to everyday life that can be caused by LBP. The total score of the RMDQ from the total number of items checked ranged from 0 (no disability) to 24 (maximum disability), where higher scores indicated greater disability.

Average LBP was assessed on an 11-point NRS captured through an IRT. Participants described their average LBP during the past 24 hours on a scale ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain.

Average LBP was assessed on an 11-point NRS captured through an IRT. The LBPI score was captured once daily from baseline up to week 16, and once weekly from week 16 to week 64. Participants described their average LBP during the past 24 hours on a scale ranging from 0 (no pain) to 10 (worst possible pain), where higher scores indicated higher pain. Pre-specified intent of study for efficacy data up to W16 was to analyze participants who received placebo from Day1 and then received tanezumab 5/10 mg at W16,together,in placebo arm.Data has been reported per four arms.

PGA of LBP was assessed by asking a question to participants: "Considering all the ways your low back pain affects you, how are you doing today?" Participants responded on a 5 point Likert scale ranging from 1-5, using IRT, where 1=very good (asymptomatic 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 which are intolerable and inability to carry out all normal activities). Higher scores indicated worsening of condition.

Chronic Low Back Pain Responder Index analysis is a composite endpoint of average low back pain intensity (aLBPI) score, PGA of Low Back Pain, and RMDQ total score. Participants were successful responders if they had: >=30 percent reduction in mean daily average LBPI from baseline to particular week; decrease of >=30 percent in PGA of low back pain from baseline to particular week or no worsening (increase) in RMDQ total score from baseline to particular week. Pre-specified intent of study for efficacy data up to W16 was to analyze participants who received placebo from Day1 and then received tanezumab 5/10 mg at W16,together,in placebo arm.Data has been reported per four arms. Also, intent of study was to compare tanezumab Vs placebo for data up to \& including W16 \& comparisons of tanezumab Vs tramadol for data up to \& including W56.

PGA of LBP assessed by asking question to participants:Considering all ways your low back pain affects you,how are you doing today? They responded on 5 point Likert scale ranging from 1-5, using IRT, where 1=very good (asymptomatic \& 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 \& inability to carry out most normal activities); \& 5=very poor (very severe symptoms which are intolerable and inability to carry out all normal activities). Higher scores indicated worsening of condition. % of participants with improvement of at least 2 points from baseline in PGA of LBP were reported. Missing data was imputed using BOCF/LOCF. Pre-specified intent of study for efficacy data up to W16 was to analyze participants who received placebo from Day1 and then received tanezumab 5/10 mg at W16,together,in placebo arm.Data has been reported per four arms.

EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Individual dimension scores ranged from 1.0 (least impairment of health state) to 5.0 (most impairment of health state). Each dimension has 5 levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems, and 5=extreme problems. The health utility score for a participant with no problems in all 5 items is 1 for all countries (except for Zimbabwe where it is 0.9), and is reduced where a participant reports greater levels of problems across the five dimensions.

Each dimension has 5 levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems, and 5=extreme problems.Responses from five domains were used to calculate a single utility index (Overall health utility score) where values are less than equal to (<=) 1.Overall health utility score for a participant with no problems in all 5 items is 1 for all countries (except for Zimbabwe where it is 0.9), and reduced where participant reports greater levels of problems across five dimensions.

WPAI: LBP is 6-question participant rated questionnaire that measures the effect of participant's chronic low back pain (CLBP) on general health and symptom severity on work productivity and regular activities. It yields 4 sub-scores: work time missed due to pain (absenteeism), impairment while working (presenteeism), overall work impairment (work productivity) and activity impairment (daily activity impairment). These sub-scores are expressed as an impairment percentage (range from 0 to 100), with higher numbers indicating greater impairment and less productivity. Pre-specified intent of study for efficacy data up to Week 16 was to analyze, participants who received placebo from Day 1 and received tanezumab 5/10 mg at week 16 in placebo arm, in pooled manner. Hence data have been reported per four arms.

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 were events between first dose of study drug and up to W56 that were absent before treatment or that worsened relative to pre-treatment state. Relatedness to study drug was assessed by the investigator. Pre-specified intent of study for summaries for the entire treatment period (up to week 56), data was summarized by 3 arms.

Measurement of BP included sitting systolic blood pressure (SBP) and diastolic blood pressure (DBP). Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

Heart rate was measured at sitting position. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

A 12-lead ECG was recorded after participants had rested for at least 5 minutes in the supine position in a quiet environment. All standard intervals {RR interval, PR interval, QRS interval, QT interval, QT interval corrected using Bazett's formula (QTcB) and QT interval corrected using Fridericia's formula (QTcF)} were collected. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

Heart rate was measured at sitting position. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

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. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms. Data not collected after W16 in placebo arm for this OM, as those who met criteria to continue, switched to active treatment with tanezumab after W16.

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. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

Incidence of participants with any of the joint safety adjudication outcomes of primary osteonecrosis, rapidly progressive OA (type 1 and type 2), subchondral insufficiency fracture (or SPONK), or pathological fracture.

Percentage of participants who underwent at least one total knee, hip or shoulder joint replacement surgery.

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. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.

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 listed as having anti-tanezumab antibodies had ADA titer level >=3.32. Less than 3.32 was considered below the limit of quantitation. Pre-specified intent of study for safety summaries until W80 was to summarize data by 4 arms.
