Brief summary

ThermoProfen is a transdermal ketoprofen patch that is integrated with a long-lasting CHADD (Controlled Heat-Assisted Drug Delivery) unit for the treatment of chronic pain associated with osteoarthritis. This study will evaluate ThermoProfen for the treatment of mild to moderate pain associated with osteoarthritis of the knee in adults.

Detailed description

The primary objective of the study is to compare the efficacy of ThermoProfen™ against two other experimental treatments. The treatment may be ThermoProfen (Matrix Transdermal Ketoprofen Patch) or a patch that may or may not include ketoprofen and that may or may not provide heat.
