Brief Summary

This is an efficacy and safety study of 3 doses (2.5 mg, 5 mg and 10mg) of tanezumab administered subcutaneously versus placebo. This study will also compare a subcutaneous (SC) administration of 10 mg of tanezumab) with an intravenous (IV) administration of 10 mg of tanezumab. Each person will receive an IV infusion and a SC infusion. The study will last 16 weeks for those who wish to enter a 64-week extension study or 24 weeks for those who do not.

Detailed Description

This study was terminated on 08 Nov 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.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 16Baseline, Week 16

The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in the index knee in the past 48 hours. It is calculated as the mean of the scores from the 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.

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale Score at Week 16Baseline, Week 16

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

Change From Baseline in Patient's Global Assessment (PGA) of Osteoarthritis Score at Week 16Baseline, Week 16

Participants answered the question: "Considering all the ways your osteoarthritis in your knee affects you, how are you doing today?" Participants responded by using a 5-point scale 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 score indicated severe condition.

Change From Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Domain Scores at Week 16Baseline, Week 16

SF-36v2 is a standardized self-administered survey evaluating 8 aspects/domains of functional health and well-being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health.

Change From Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Physical and Mental Component Scores at Week 16Baseline, Week 16

SF-36v2: standardized self-administered survey evaluating 8 aspects of functional health and wellbeing (physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health). Total score for each aspect were scaled 0-100 (100=highest level of functioning). For obtaining physical and mental component scores, z-score for each scale=(observed score - mean score for general 1990 United States \[US\] population)/corresponding standard deviation. The 2 component scores were obtained by multiplying each aspect z-score by physical or mental factor score coefficient (1990 general US population) and summing the eight products. Component scores indicated how many standard deviations higher (in case of positive z-score \[better functioning\])/lower (in case of negative z-score \[worse functioning\]) participant's value was relative to the mean of the reference population.
