Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The diagnosis of hip OA, which was having hip pain and meeting criteria for at least 2 of the following: a. Westergren erythrocyte sedimentation rate of \< 20 mm/hr; b. radiographic femoral or acetabular osteophytes or c. radiographic joint space narrowing
  • Knee OA diagnosis required diagnosing (by modified American College of Rheumatology criteria) OA of the knee with pain plus at least one of the following: a. Age\> 50 years old, b. Stiffness \< 30 minutes, c. crepitus on active motion and radiographic evidence of OA of the knee, defined as presence of osteophytes or joint space narrowing
  • Symptomatic OA of the knee or hip was determined at the Baseline Visit, if the Patient's Assessment of Arthritis Pain was at least 40 mm VAS, Patient's and the Physician's Global Assessment of Arthritis was "poor" or "very poor"

You may not qualify if:

  • Use of NSAIDs or analgesics within 2 days (within 4 days for subjects taking oxaprozin, piroxicam or full dose aspirin) before baseline arthritis assessments
