Primary Outcome(s)

Secondary Objective: The secondary objectives include:
• Comparison of the effect of CG5503 IR on the time to the first rescue pain medication during the double-blind treatment period
• Evaluation of the effect of CG5503 IR versus placebo with the distribution of responder rates for each time point (at 12, 24, 48, and 72 hours)
• Evaluation of the efficacy of CG5503 IR by examining the total effect on pain relief and pain intensity over the 72-hour double-blind period.
• Assessment of the Patient Global Impression of Change (PGIC) at the end of the double-blind treatment period.
• Evaluation of the adverse event rates across treatment groups in the double-blind treatment period (especially nausea and vomiting)

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 48 hours compared to placebo, and to assess the safety and tolerability of multiple doses of CG5503 IR in subjects with acute pain following primary unilateral total hip replacement surgery over the double-blind period.

Primary end point(s): The primary efficacy endpoint for this study is the sum of pain intensity difference over 48 hours (SPID48). The SPID48 will be calculated as the weighted sum of the pain intensity difference (difference between baseline at qualifying period and current pain intensity) collected up to 48 hours.
