Products containing IR opioid analgesics taken 4 days each week or less are allowed • Products containing IR opioid analgesics must be discontinued prior to the run-in period. The non-opioid component of combination products may be continued during the study. • History of malignancy within the past 2 years, with the exception of basal cell carcinoma • Concomitant autoimmune inflammatory conditions involving the target joint • Acute crystal-induced arthropathy within the past 6 months before screening • Systemic steroid therapy, excluding inhalers, within 4 weeks before screening • Presence of any of the following: – Major trauma to the target joint in the 6 months preceding study screening – Infection in the target joint in the 6 months preceding study screening – Apparent avascular necrosis in the target joint in the 6 months preceding study screening – Intra-articular injections of corticosteroids or hyaluronan injections in the target joint in the 3 months preceding study entry • Women who plan to become pregnant during the study, or who are breast feeding • Laboratory values reflecting moderate or severe renal insufficiency • Moderately or severely impaired hepatic function, or subjects with alanine aminotransaminase (ALT) or aspartate aminotransferase (AST) greater than 3 times the upper limit of normal (ULN) • Contraindication to, or history of allergy to, or hypersensitivity to CG5503, oxycodone, or their excipients • Plan to undergo surgery or other procedures during the course of the study • Has a clinically significant disease that in the investigator's opinion may affect efficacy or safety assessments • Employees of the investigator or study center, with involvement in the proposed study or other studies under the direction of that investigator or study center, including family members of the employees or the investigator

Primary Outcome(s)
|
Secondary Objective: The secondary objectives include: • Compare the effect of CG5503 IR with placebo in time to the first rescue pain medication during the double blind treatment period • Evaluate the effect of CG5503 IR with the distribution of responder rates based on percent change from baseline in pain intensity (PI) for each of the time point (Day 2, 5, and 10) • Demonstrate the efficacy of CG5503 IR using total pain relief (TOTPAR) and sum of total pain relief and sum of pain intensity difference (SPRID) over 2, 5, and 10 days; and SPID over 2 and 10 days • Evaluate patient global impression of change (PGIC) of study treatment at the end of the double blind treatment period • Evaluate the adverse event rates across treatment groups (especially nausea and vomiting) • Explore sleep quality and bowel movement using questionnaires • Explore the efficacy of oxycodone IR in comparison with CG5503 IR and placebo
|
Main Objective: The primary objective of this study is to determine the efficacy of CG5503 immediate-release (IR) using the sum of pain intensity difference (SPID) over 5 days compared with placebo, and to assess the safety and tolerability of multiple doses of CG5503 IR in subjects who are eligible for elective primary total or partial joint replacement of the hip or knee due to chronic osteoarthritis. The null hypothesis is that all CG5503 IR dosage efficacy results are equal to placebo based on 5 day SPID in the treatment of chronic pain from end-stage degenerative joint disease of the hip or knee. The alternative hypothesis is that at least one CG5503 IR dose effect will be different from placebo effect.

Primary end point(s): The measurements used for the efficacy evaluations in this study include PI, pain relief, and the PGIC. The details are presented below. • Pain Intensity – 11 Point Numerical Rating Scale The subject will indicate the current PI on a 11-point (0 to 10) NRS in response to the following question: “What is your pain level for the past 12 hours?” • Pain Relief – 5-Point Numerical Rating Scale The subject will indicate their pain relief on a 5-point (0 to 4) NRS at the same time points as PI in response to the following question: “How much relief have you had from your starting pain?” • Patient Global Impression of Change The subjects will indicate their response (1 to 7) to the following statement: "Since I began study medication, my overall status is:" The primary efficacy variable is the 5-day SPID. • Pain Intensity Difference The pain intensity difference (PID) will be calculated at each assessment time point, using the following formula: PID=Baseline PI-Current PI, where baseline PI is the mean PI collected during the last 3 days of pain assessments during the run-in period. • Sum of Pain Intensity Difference The SPID will be calculated over 5, days using the following formula: SPID=?Wi*PIDi; where the sum includes all observations collected from baseline to the end of Day 5 and Wi is the time elapsed from the previous observation (PIDi-1) to the current observation (PIDi).
