A Phase 3 Study of Tanezumab for Chronic Low Back Pain (TANGO)

February 6, 2020 updated by: Pfizer

A PHASE 3, RANDOMIZED, DOUBLE BLIND, PLACEBO AND ACTIVE-CONTROLLED, MULTICENTER, PARALLEL-GROUP STUDY OF THE ANALGESIC EFFICACY AND SAFETY OF TANEZUMAB IN ADULT SUBJECTS WITH CHRONIC LOW BACK PAIN

This study will investigate the efficacy and safety of tanezumab 5 mg and 10 mg administered by subcutaneous injection seven times at 8 week intervals (56 weeks). The primary objective of this study is to evaluate the effectiveness of tanezumab 10 mg and 5 mg compared to placebo for the treatment of chronic low back pain. Secondary objectives are to evaluate the long-term safety and effectiveness of tanezumab 10 mg and 5 mg compared to placebo for the treatment of chronic low back pain. In addition, the study will evaluate the effectiveness and long term safety profile of tanezumab treatment for chronic low back pain compared to tramadol Prolonged Release (PR), a medication commonly utilized for the treatment of chronic low back pain.

Study Overview

Detailed Description

This is a randomized, double blind, placebo and active controlled, multicenter, parallel group Phase 3 study of the efficacy and safety of tanezumab when administered by SC injection for up to 56 weeks in subjects with chronic low back pain. Approximately 1800 subjects will be randomized to 1 of 4 treatment groups in a 2:2:2:3 ratio (ie, 400 subjects per treatment group for the placebo, tanezumab 5 mg and tanezumab 10 mg treatment groups and 600 subjects in the tramadol PR treatment group). Treatment groups will include: 1.) Placebo administered SC at an 8 week interval plus placebo matching tramadol PR up to Week 16. At the Week 16 visit, subjects in this group who meet the efficacy responder criteria will be switched in a blinded fashion in a 1:1 ratio to either tanezumab 5 mg or tanezumab 10 mg administered SC at an 8 week interval plus placebo matching tramadol PR to Week 56; 2.)Tanezumab 5 mg SC administered at an 8 week interval plus placebo matching tramadol PR to Week 56; 3.) Tanezumab 10 mg SC administered at an 8 week interval plus placebo matching tramadol PR to Week 56; 4.) Oral tramadol PR plus placebo administered SC at an 8 week interval to Week 56. The study is designed with a total duration (post randomization) of up to 80 weeks and will consist of three periods: Screening (up to a maximum of 37 days; includes a Washout Period and an Initial Pain Assessment Period), a Double blind Treatment Period (comprised of a 16 week Primary Efficacy Phase and a 40 week Long Term Safety and Efficacy Phase), and a Follow up Period (24 weeks). The Screening Period (beginning up to 37 days prior to Randomization) includes a Washout Period (lasting 2 32 days), if required, and an Initial Pain Assessment Period (the 5 days prior to Randomization/Baseline). Prior to entering the study, subjects must have a documented history of previous inadequate treatment response to medications in 3 different categories of agents commonly used to treat and generally considered effective for the treatment of chronic low back pain.

For the Average Pain item of the BPI-sf scale (11 point NRS scale; range: 0 [no pain] to 10 [pain as bad as you can imagine]), participants were asked to rate their pain by marking an "X" in one of the boxes that best described their pain during 24 hours prior to evaluation, higher scores indicated greater pain severity. Question 5 (7-items) assessed level of pain interference on daily activities.

Time Frame: Baseline, Weeks 8, 16, 24, 40 and 56
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.

Number of Participants With Confirmed Orthostatic Hypotension
Time Frame: Baseline, Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80
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.

Change From Screening in Survey of Autonomic Symptom (SAS) Scores at Weeks 24, 56 and 80
Time Frame: Screening (up to maximum of 37 days prior to Baseline), Weeks 24, 56 and 80
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.

Time Frame: Baseline, Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80
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.
Baseline, Weeks 2, 4, 8, 16, 24, 32, 40, 48, 56, 64 and 80
Number of Participants With Anti Tanezumab Antibodies
Time Frame: Baseline, Weeks 8, 16, 32, 40, 48, 56, 64 and 80
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.
