Outcome Measures

Primary Outcomes (1)

  • Daily Pain Numeric Rating Scale (NRS)

    The endpoint average pain score, based on the mean of the last 7 days' daily pain numeric rating scale (NRS) scores at (NRS is an 11-point scale where 0 = no pain and 10 = worst possible pain) from the daily pain diaries while receiving study medication during the treatment period.

    Baseline, Week 1, Week 2, Week 3 and Week 4

Secondary Outcomes (17)

  • Responder Rate Based on a 30% Improvement in Mean Pain Response Using the Daily Pain NRS Score

    Baseline, Week 1, Week 2, Week 3 and Week 4

  • Responder Rate Based on a 50% Improvement in Mean Pain Response Using the Daily Pain NRS Score

    Baseline, Week 1, Week 2, Week 3, and Week 4

  • Neuropathic Pain Symptom Inventory (NPSI) - Burning (Superficial) Spontaneous Pain

    Baseline, Week 2, and Week 4

  • Neuropathic Pain Symptom Inventory (NPSI) - Pressing (Deep) Spontaneous Pain

    Baseline, Week 2 and Week 4

  • Neuropathic Pain Symptom Inventory (NPSI) - Paroxysmal Pain

    Baseline, Week 2, and Week 4

  • +12 more secondary outcomes

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women aged 18 years to 80 years.
