  Purpose
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.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment

Primary Outcome Measures:
  • The primary outcome measure is the change from baseline in the Visual Analog Scale score for the average pain during the previous 24 hours. [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • Change from baseline in Visual Analog Scale score for worst pain during the previous 24 hours, amount of rescue medication used to treat the target joint per day, and the patient global impression of change in the Likert Scale [ Time Frame: 12 weeks ]

Enrollment: 679
Study Start Date: June 2007
