The purpose of this study is to evaluate the safety profile of CG5503 PR at doses 100 mg - 250 mg administered twice daily over a maximum one year period to patients with at least 3-month history of low back pain, or pain caused by knee or hip osteoarthritis.

Official Title: | A One-Year, Randomized, Open-Label, Parallel-Arm, Phase 3 Long-Term Safety Trial, With Controlled Adjustment of Dose, of Multiple Doses of CG5503 PR and Oxycodone CR in Subjects With Chronic Pain |
Estimated Enrollment: | 1075 |
Study Start Date: | October 2006 |
CG5503 is a centrally active pain-relieving drug being investigated for the treatment of acute and chronic pain. This study is a randomized (patients are assigned different treatments based on chance), open-label (both the Investigator and the patient know what medication is allocated), active-controlled, parallel-group, multicenter study. It is designed to investigate the long-term safety (side effects during up to one year of administration) and effectiveness (level of pain control) of CG5503 PR compared to oxycodone (an opioid commonly used for relief of moderate to severe pain). The doses of both of these medications will be adjusted to give the best therapeutic benefit for the patient. Approximately 1075 patients will be screened. Safety evaluations include monitoring of adverse events, physical examinations, and clinical laboratory tests. Assessments of pain relief include the pain intensity numeric rating scale, and patient global impression of change scale (PGIC). Venous blood samples will be collected for the determination of serum concentrations of CG5503 and oxycodone.
Patients will start taking CG5503 PR 50 mg BID or oxycodone CR 10 mg. After 3 days (6 consecutive doses), the dose will be increased: CG5503 to 100 mg BID, oxycodone to 20 mg. The patient will remain on this dose for the next 4 days.During maintinance phase, upward titration may occur at a minimum of 3 day-intervals in increments of CG5503 PR 50 mg BID or oxycodone 10 mg BID. The maximum doses are CG5503 PR 250 mg BID or oxycodone 50 mg BID.
