Detailed Description:

This study was terminated on 28 October 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.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Osteoarthritis of the knee or hip according to ACR criteria with Kellgren-Lawrence x-ray grade equal to, or greater than, 2.
  • Patients must be experiencing some benefit from their current stable dose regimen of oral NSAID therapy of either naproxen 500-1000 mg/day or celecoxib 200 mg/day (either 100 mg BID or 200 mg QD) and be tolerating their NSAID regimen.
