Phase 3
Completed
Conditions
Post-herpetic neuralgia
Registration Number

Brief Summary

In this study, DS-5565 was administered at doses of 15 mg QD, 10 mg BID, or 15 mg BID for 14 weeks, including the titration period, to evaluate the efficacy and safety of DS-5565 in Asian patients with PHN. The mean changes from baseline in ADPS at Week 14 were greater as the daily dose of DS-5565 was increased, and the differences versus placebo were statistically significant in all DS-5565 treatment group.
