Summary

The main objective of this trial is to demonstrate the efficacy and safety of multiple-dose application of oral application of CG5503 IR 75mg compared to placebo and to assess safety and tolerability of CG5503 IR 75mg in subjects following bunionectomy. This trial was performed based on a previously performed double-blind, placebo-controlled, multiple-dose trial in the same indication investigating 3 dose strengths CG5503 IR (50, 75 and 100 mg) published under PMID: 18851776.
