Brief summary
Ketoprofen in a topical patch formulation has been demonstrated to be effective for treating mild to moderate pain caused by various musculoskeletal disorders.
Detailed description
The objective of this study is to demonstrate the short-term multiple dose efficacy and safety of HKT-500 in subjects with pain caused by mild to moderate osteoarthritis of the knee. The goal of the study is to gather additional information about the analgesic efficacy and safety of repeated, 24-hour applications of 2 HKT-500 patches per knee for a total of 28 days in subjects with pain caused by mild to moderate osteoarthritis of the knee.
