Outcomes

Primary Outcome Measures

Change in the Average Daily Pain Score (ADPS) From Baseline to Week 14 Following Administration of DS-5565 in Participants With Diabetic Peripheral Neuropathic Pain
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.

Secondary Outcome Measures

Change in Visual Analog Scale From Baseline (Week 14) to Week 66 Following Administration of DS-5565 in Participants With Diabetic Peripheral Neuropathic Pain
Visual Analog Scale (VAS) pain is a 10-point assessment tool to measure pain levels, where 0 is defined as 'no pain' and 10 is defined as 'worst possible pain'. Higher VAS pain scores indicate worse outcome. In this outcome, the change from baseline in VAS pain is being reported with negative values representing improvements in pain intensity. The larger the negative value (ie. improvement), the greater the improvement in pain intensity.

5. Study Description

Brief Summary
Investigate the efficacy and safety of DS-5565 in subjects with Diabetic Peripheral Neuropathic Pain (DPNP) in comparison to placebo
Detailed Description
[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 DPNP 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 DPNP.
