About
The purpose of this study was to assess analgesic efficacy of ASP8062 relative to placebo as well as the safety and tolerability. This study also assessed the treatment differences in physical function as well the improvements in overall subject status (e.g., fibromyalgia symptoms, global functioning) of ASP8062 relative to placebo.
