4-Week Randomized Multicenter DB, Placebo- and Active-controlled, Parallel-group, Forced-titration Phase 2B Study of Efficacy and Safety With CG5503 Prolonged Release (PR) to 233 mg BID and Oxycodone PR to 20 mg BID vs Placebo in Subjects With Moderate to Severe Chronic Pain of Knee Osteoarthritis

Brief Summary
The purpose of this study was to examine a low and high dose of tapentadol extended release tablet taken orally twice a day to reduce pain in subjects suffering from chronic moderate to severe pain due to osteoarthritis of the knee during a 4-week period. Subjects steadily increased their dose up to the low (100 mg) or high (200 mg) dose. Pain relief was compared to subjects taking placebo tablets or oxycodone extended release tablet, 20 mg. The serum concentrations and safety of tapentadol and oxycodone were also examined.
