The primary objective of this randomized-withdrawal (randomized means study medication assigned to patients by chance and withdrawl means to stop using), multicenter, double-blind (neither patient nor investigator knows the study medication), placebo-controlled, Phase 3 study is to determine the effectiveness and safety of orally administrated Tapentadol (CG5503) extended release (ER) (base) at doses of 100-250 mg twice daily in patients with moderate to severe pain from diabetic peripheral neuropathy. The study is being conducted for registration and approval of CG5503 in the US and outside US. The trial will consist of two phases: Phase I is open-label and Phase 2 is double- blind. In the Open-Label Phase 1 there will be four periods: screening (to assess eligibility)
Titrate Tapentadol (CG5503) extended release (ER) 50 mg to patient's optimal dose ranging between 100mg and 250mg twice a day; Placebo (no active ingredients). All doses of trial treatment will be taken orally with or without food, for a maximum timeframe of 15 weeks.
