About this trial
This is an interventional treatment trial for Osteoarthritis focused on measuring knee, OA patients
Eligibility Criteria
Inclusion Criteria:
- Korean outpatients with symptomatic radiologic evidence of OA of the knee (diagnosed according to the modified American College Rheumatology criteria)
- Patient's Assessment of Arthritis Pain measurement of at least 40 mm on VAS
- Patients had not received any NSAIDs or analgesics within 2 days (within 4 days for subjects taking oxaprozin, piroxicam or full dose aspirin) prior to the Baseline Visit
Exclusion Criteria:
- Diagnosis of inflammatory arthritis, gout, pseudogout, Paget's disease, or any chronic pain syndrome that, in the Investigator's opinion, would interfere with the assessment of the Index Knee
- Symptomatic anserine bursitis or acute joint trauma of the Index Knee
- Arthroscopy performed on the Index Knee within the past 12 months
- Complete loss of articular cartilage of the Index Knee
- Administration of oral, or intramuscular, intravenous, or soft tissue injections of corticosterosteroids within 4 weeks prior to screening visit

5. Study Description
Brief Summary
This study was performed to demonstrate that treatment with valdecoxib 10 mg daily (QD) was at least as effective as with naproxen 500 mg twice daily (BID), a standard non-steroidal anti-inflammatory drug (NSAID), when taken for 6 weeks in Korean subjects with symptomatic osteoarthritis (OA) of the knee. Secondary objectives were to assess the overall safety and tolerability of valdecoxib 10 mg QD taken for 6 weeks in Korean subjects with symptomatic OA of the knee.
