Outcome Measures
Primary Outcomes (1)
Neuropathic Pain in Subjects With Peripheral Neuropathic Pain Conditions During the Double-blind Phase
Pain score end of Double-Blind treatment = mean of last 7 available pain scores from daily pain diary while on Double-Blind treatment. A Daily Pain Rating Score : 11- point numerical scale ranging from 0 ("no pain") to 10 ("worst possible pain").
9 weeks
Secondary Outcomes (18)
Weekly Mean Pain Scores During the Single-blind Treatment Phase
0 and 4 weeks
Weekly Mean Pain Scores During the Double Blind Treatment Phase
Week 4 - 9
Change in Pain Scores During Double Blind Treatment Phase

Number of Subjects With >= 30% Reduction in Mean Pain Score During Single-blind Treatment
Week 4 (end of single-blind treatment phase)
Mean Pain Score for Responders at End of Single-blind Treatment Phase. Change From Baseline of Mean of Last 7 Available Pain Scores From Daily Pain Diary While on Single-blind Treatment.

Eligibility Criteria
You may qualify if:
- Subjects presenting a diagnosis of peripheral neuropathic pain, defined as pain caused by a lesion of the peripheral nervous system manifesting with sensory symptoms and signs, for at least 6 months at screening.
- At baseline, subjects must have completed at least 4 daily pain diaries and must have a mean weekly pain score equal or greater than 4.
You may not qualify if:
- Presence of any of the following diagnoses: Cervical or lumbo-sacral radiculopathy; Operated or non-operated chronic low back pain Carpal tunnel syndrome or any other entrapment-related neuropathic pain (defined as pain associated with focal nerve lesion produced by constriction or mechanical distortion of the nerve, within a fibrous or fibro-osseous tunnel, or by a fibrous band) ; Complex regional pain syndrome (type 1 and 2); Fibromyalgia.
