Evaluate the Analgesic Efficacy and Safety of VVZ-149 Injection for Post-operative Pain Following Gastrectomy

• Status: Completed
• Trial end date: 2016-02-01
• Target enrollment: 0
• Participant gender: All

Summary

VVZ-149 is a novel analgesic drug candidate that shows a potential analgesic activity inhibiting GlyT2 and 5HT2A simultaneously. These target receptors have been known to play important roles in induction and transmission of pain signals. There have been many efforts to develop selective drugs to treat pain, but usually unsuccessful due to the lack of efficacy or limitations of single-target approach for new drug discovery. VVZ-149 is expected to be a dual-target drug, demonstrated having a potential synergism between GlyT2 and 5HT2A to maximize an antinociceptive effect in the in vivo animal models. In Phase 1 conducted among healthy subjects, safety and tolerability were confirmed. Phase 2 was designed as a randomized, double-blind, parallel-group, placebo-controlled trial to evaluate the efficacy and safety of the analgesic drug VVZ-149 injection.
