A Phase 2a, Randomized, Double-Blind Placebo-controlled, Parallel-group Study to Assess the Analgesic Efficacy and Safety of ASP8062 in Subjects With Fibromyalgia

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.

palpation should be performed with an approximate force of 4 kg.

3-6 and SS scale score ≥ 9.

- Symptoms have been present at a similar level for at least 3 months.

- The subject does not have a disorder that would otherwise explain the pain.

- Subject has a pain score ≥ 4 on the revised fibromyalgia impact questionnaire (FIQR)
pain item at Screening.

- Subject is compliant with daily pain recordings during the Baseline Diary Run-In
period, as defined by the completion of a minimum of 5 of 7 daily average pain ratings
and agrees to complete daily diaries throughout the duration of the study.

- Subject has a mean daily average pain score ≥ 4 and ≤ 9 on an 11-point 0 to 10 NRS as
recorded in the subject e-diary during the Baseline Diary Run-In period, and meeting
pre-specified criteria for daily average pain scores.

- Subject agrees to use only acetaminophen as rescue medication for fibromyalgia pain
throughout the course of the trial (up to 1000 mg per dose and not to exceed 3000
mg/day).

- Subject agrees not to initiate or change any non-pharmacologic interventions
(including normal daily exercise routines, chiropractic care, physical therapy,

associated formulation components; known hypersensitivity to the formulation
components of ASP8062.

- Subject has pain due to diabetic peripheral neuropathy, post-herpetic neuralgia,

pain that would confound or interfere with the assessment of the subject's
fibromyalgia pain or require excluded therapies during the subject's study
participation.

ankylosing spondylitis, psoriatic arthritis, gout), autoimmune disease (for example,
systemic lupus erythematosus), or other widespread rheumatic disease other than
