简要总结
Investigate the efficacy and safety of DS-5565 in subjects with Post-Herpetic Neuralgia (PHN) in comparison to placebo
详细描述
[Double Blind Phase] The primary objective is to compare change in the Average Daily Pain Score (ADPS) from baseline to Week 14 in Asian subjects with PHN receiving DS-5565 versus placebo.
[Open Extension Phase] The objective is to assess the long-term safety and efficacy of DS-5565 in subjects with PHN.

结局指标
主要结局
Change in the Average Daily Pain Score (ADPS) From Baseline to Week 14 Following Oral Administration of DS-5565 in Asian Participants With Post-herpetic Neuralgia
时间窗: Baseline to Week 14
Each participant recorded a pain score in the electronic patient diary once daily from the day after the screening visit (Visit 1) to the end of treatment/early termination visit (Visit 10). Prior to taking the study drug each morning, the participant selected the number that best described his or her pain over the past 24 hours on a scale of 0 (no pain) to 10 (worst possible pain). Higher ADPS scores indicated worse outcome. ADPS was the weekly average pain score based on the pain scores from the electronic patient diaries (Pain diary). In this outcome, the change from baseline in ADPS is being reported with negative values representing improvements in average daily pain. The larger the negative value (ie. improvement), the greater the improvement in average daily pain.
次要结局
