  Purpose

Oral non-steroidal anti-inflammatory drugs (NSAIDs) are a recommended treatment for the symptoms of osteoarthritis of the knee. However, NSAIDs may cause a range of negative side effects, including stomach pain, heartburn, bleeding stomach ulcer, and liver or kidney abnormality. A topical NSAID may relieve pain and other symptoms of osteoarthritis of the knee, while minimizing the side effects common to oral NSAIDs. The purpose of this study is to determine the safety and effectiveness of a topical NSAID when used alone or when combined with an oral NSAID in the treatment of osteoarthritis of the knee.

Primary Outcome Measures:
  • pain
  • physical function
  • patient overall health assessment

Secondary Outcome Measures:
  • stiffness
  • patient global assessment

Estimated Enrollment: 750
Study Start Date: February 2004
Estimated Study Completion Date: September 2005
Detailed Description:

During this 12-week study, patients will visit the study clinic 5 times. At the screening visit, the patient's demographic information, medical and medication history will be recorded and a physical examination performed. After washout of all NSAIDs/other analgesic medication, the patient will return for the baseline visit. During the treatment phase of the study, the patient will apply a topical solution to his/her osteoarthritic knee and take an oral study tablet. The patient may randomly receive active treatment with topical diclofenac, oral diclofenac, both, or neither (placebo). Follow-up clinic visits are conducted at 4, 8 and 12 weeks. Routine laboratory analyses are done at baseline, 4 and 12 weeks.
