Study of the Analgesic Efficacy and Safety of Subcutaneous Tanezumab in Subjects With Osteoarthritis of the Hip or Knee.

Tanezumab is a monoclonal antibody that binds to and inhibits the actions of nerve growth factor (NGF). The Nerve Growth Factor Inhibitor (NGFI) class may offer an important breakthrough in the treatment of chronic pain and is under clinical investigation for the treatment of pain associated with osteoarthritis or other chronic pain conditions.

The primary objective of this study is to demonstrate superior efficacy of tanezumab 5 mg and 2.5 mg administered subcutaneously (SC) every 8 weeks versus placebo at Week 24 in subjects with osteoarthritis of the knee or hip. The 2.5 mg dose was shown to provide efficacy benefits with a favorable safety profile when administered intravenously in previous Phase 3 clinical trials. The 5 mg dose is expected to provide added efficacy benefit over the 2.5 mg dose based on data from previous studies.

About this study

This is a randomized, double blind, placebo controlled, parallel group multicenter Phase 3 study of the efficacy and safety of tanezumab when administered by SC injection for 24 weeks compared to placebo in subjects with osteoarthritis of the knee or hip. A total of approximately 810 subjects will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (ie, 270/group). The randomization will be stratified by index joint (hip or knee), and most severe Kellgren-Lawrence grade (of any knee or hip joint) at study entry (grade 2, 3 or 4). Subjects will receive up to three SC doses of one of the following treatments at an 8-week interval between each injection:

  • tanezumab 2.5 mg;
  • tanezumab 5 mg;
  • Placebo to match tanezumab. The study is designed with a total (post-randomization) duration of 48 weeks and will consist of three periods: Screening (up to 37 days), Double-blind Treatment (24 weeks) and Safety Follow-up (24 weeks). The Screening Period (beginning up to 37 days prior to Randomization) includes a Washout Period (lasting a minimum of 2 days for all prohibited pain medications), if required, and an Initial Pain Assessment Period (the 7 days prior to Randomization/Baseline).

Week 24 is the landmark analysis in this study. Subjects who do not complete the Double-blind Treatment period will enter and complete the 24-week Early-termination follow-up period.

Primary outcomes

  1. Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale at Week 24

    Time frame: Baseline, Week 24

The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to OA of index joint (knee or hip) during past 48 hours. It was calculated as the mean of scores from 5 individual questions scored on a numerical rating scale (NRS). Scores for each question and WOMAC Pain subscale score on NRS ranged from 0 (no pain) to 10 (extreme pain), where higher scores indicated higher pain.

  2. Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale at Week 24

    Time frame: Baseline, Week 24

    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. 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 the five domains were used to calculate a single utility index (the Overall health utility score) where values are less than equal to (<=) 1. The 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 is reduced where a participant reports greater levels of problems across the five dimensions.
