Registration Number
NCT00994890
Lead Sponsor
Pfizer
Brief Summary

This study will investigate the safety of three fixed dose levels of tanezumab (2.5 mg, 5 mg, and 10 mg) administered at an 8-week interval by subcutaneous injection multiple (7) times during the study treatment period.

Detailed Description

Safety study of tanezumab in relief of osteoarthritis pain This study was terminated on 6 December 2010 following a US FDA clinical hold for tanezumab osteoarthritis clinical studies which halted dosing and enrollment of patients on 23 June 2010 for potential safety issues.

WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee or index hip during past 48 hours. It is calculated as mean of the scores from 5 individual questions scored on a numerical rating scale (NRS) of 0 to 10, where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 to 10, where higher scores indicate higher pain. Participants with specified reduction (as percent) from baseline at Week 16 are reported.

WOMAC physical function subscale is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in index joint and index hip during past 48 hours. It was calculated as mean of the scores from 17 individual questions scored on NRS of 0 to 10, with higher scores indicated worse function. Total score range for WOMAC physical function subscale score was 0 to 10, where higher scores indicated worse function.

WOMAC stiffness subscale is a 2-item questionnaire used to assess the amount of stiffness experienced due to osteoarthritis in index knee or index hip during past 48 hours. It is calculated as mean of the scores from 2 individual questions scored on NRS of 0 to 10, with higher scores indicate higher stiffness. Total score range for WOMAC stiffness subscale score is 0 to 10, where higher scores indicate higher stiffness. Stiffness is defined as a sensation of decreased ease in movement of knee or hip.

Percentage of participants with at least 30%, 50%, 70% and 90% reduction from baseline in WOMAC pain subscale score are reported. WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee or index hip during past 48 hours. It was calculated as mean of the scores from the 5 individual questions scored on a 0 to 10 NRS, where higher scores indicated higher pain. Total score range for WOMAC pain subscale score is 0 to 10, where higher scores indicated higher pain.

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Average Score at Week 2, 4, 8, 16, 24, 32, 40, 48 and 56Baseline, Week 2, 4, 8, 16, 24, 32, 40, 48, 56

WOMAC: self-administered, disease-specific 24-item questionnaire which assesses clinically important, participant-relevant symptoms for pain (5 items), stiffness (2 items) and physical function (17 items) in participants with osteoarthritis of knee or hip. Each item was scored on a 0 to 10 NRS scale, where higher scores indicated higher pain/stiffness or worse function. WOMAC average score was the mean of WOMAC pain, physical function and stiffness subscale scores and ranged from 0 to 10, where higher score indicated worse response.
