An Evaluation of the Effectiveness and Tolerability of Tapentadol Hydrochloride Prolonged Release, and Tapentadol Hydrochloride Immediate Release on Demand, in Subjects With Uncontrolled Severe Chronic Pain Due to Osteoarthritis of the Knee Taking Either WHO Step I or Step II Analgesics or no Regular Analgesics.
In Brief
A Phase 3 clinical trial evaluating Tapentadol for Chronic Pain and Osteoarthritis. Completed, enrolled 224 participants across 24 sites in 5 countries.
Detailed Summary
The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in participants suffering from severe chronic pain due to osteoarthritis of the knee who are taking either WHO Step I or Step II analgesics or no regular analgesics. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome. The trial will compare the effectiveness of previous analgesic treatment (either WHO Step I or Step II analgesics or no regular analgesics) with that of tapentadol hydrochloride prolonged release (PR) treatment during defined periods of evaluation.
