Brief Summary:
The purpose of this study is to assess the painkilling efficacy of ASP8477 relative to mock (placebo) in patients that have been diagnosed with painful diabetic peripheral neuropathy or postherpetic neuralgia determined by the change in the average daily pain intensity in patients that initially respond favorably to treatment with ASP8477.

Condition or disease Intervention/treatment Phase
Post-Herpetic Neuralgia (PHN) Neuropathic Pain Painful Diabetic Peripheral Neuropathy (PDPN) Drug: ASP8477 Drug: Placebo Phase 2

The study will consist of a Screening Period, Single-Blind Treatment Period, Double-Blind Randomized Withdrawal Period and Follow-up Period.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 132 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 2a Enriched Enrollment Randomized Withdrawal Study to Assess Analgesic Efficacy and Safety of ASP8477 in Subjects With Peripheral Neuropathic Pain
Actual Study Start Date : February 24, 2014

Arm Intervention/treatment
Placebo Comparator: Placebo
Drug: Placebo
Active Comparator: ASP8477
Drug: ASP8477

Primary Outcome Measures :
  1. Change in mean of 24-hour average pain intensity, Numeric pain rating scale (NPRS) [ Time Frame: Baseline of the double-blind randomized withdrawal period to the last 3 days of double-blind randomized withdrawal period ]

Secondary Outcome Measures :
  1. Time to treatment failure [ Time Frame: Date of randomization to first 3 consecutive days of double-blind period with an observed treatment failure ]
    Treatment failure is defined as mean 24 hour pain intensity was equal or more than 4 with at least a 30% increase in pain intensity relative to baseline of the double-blind randomized withdrawal period

  2. Responder rate to ASP8477 in the Single-Blind Period [ Time Frame: Baseline of the single-blind period (last 3 days of the placebo run-in period) to baseline of the double-blind period (last 3 days of the single-blind period ]
  3. Patient Global Impression of Change (PGIC) score [ Time Frame: From the baseline of the single-blind period to End of Treatment Visit (Day 49 or upon early discontinuation) ]
  4. Safety assessed by TEAE and SAE, laboratory tests, vital signs, C-SSRS, PWC and MWC scores, Bond-Lader score [ Time Frame: From Screening to End of Study Visit (13 weeks) ]
    TEAE=Treatment Emergent Adverse Events, SAE = Serious Adverse Event, C-SSRS = Columbia Suicide Severity Rating Scale, PWC = Physician Withdrawal Checklist, MWC = Marijuana Withdrawal Checklist

  5. Composite of pharmacokinetics of ASP8477 concentration: Trough concentration (Ctrough), observed maximum concentration (Cmax), Area under the curve (AUC)0-6 [ Time Frame: Day 14 ]
