- Number of Subjects With Adverse Events (AEs) Reported Spontaneously by the Subject or Observed by the Investigator. [ Time Frame: Throughout the study up to a maximum study period of 2.8 years ]Number of subjects with adverse events (AEs) reported spontaneously by the subject or observed by the investigator (serious and non-serious).

[ Time Frame: Baseline to end of entire treatment phase (maximum study period of 2.8 years). ]Change from Baseline in average daily pain score using an 11-point Likert scale (0-10). On Likert scale, 0=no pain and 10=worst possible pain.
- Change From Baseline in Average Pain Score as Measured by a 100mm Visual Analogue Scale (VAS). [ Time Frame: Baseline to end of entire treatment phase (maximum study period of 2.8 years). ]Change from Baseline in average pain score as measured by a 100mm Visual Analogue Scale (VAS). On VAS 0mm=no pain and 100mm=worst possible pain.
- Patient's Global Impression of Change (PGIC) From Baseline in Pain. [ Time Frame: Baseline to Termination Visit ]Patient's Global Impression of Change (PGIC) from Baseline in Pain. Original categorical responses are much worse, moderately worse, mildly worst, no change, mildly better, moderately better, and much better. Reported results are presented as Better (sum of mildly, moderately, or much better), No Change, or Worse (sum of mildly, moderately, or much worse).
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Intensity. [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) for intensity of pain where 0=no pain and 10=most intense pain sensation imaginable.
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Sharpness [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) for sharpness of pain where 0=not sharp and 10=most sharp sensation imaginable ("like a knife").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Heat [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with heat sensation where 0=not hot and 10=the most hot sensation imaginable ("on fire").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Dullness [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with dullness of pain where 0=not dull and 10=most dull sensation imaginable.
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Cold [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with cold sensation where 0=not cold and 10=most cold sensation imaginable ("freezing").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Sensitivity [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with sensitivity of pain where 0=not sensitive and 10=most sensitive sensation imaginable ("raw skin").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Itchiness [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with itchiness where 0=not itchy and 10=most itchy sensation imaginable ("like poison oak").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Unpleasantness [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with unpleasantness where 0=not pleasant and 10=most unpleasant sensation imaginable ("intolerable").
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Deep Pain [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with deep pain where 0=no deep pain and 10=most intense deep pain sensation imaginable.
- Within-subject Change in Neuropathic Pain Using the Neuropathic Pain Scale (NPS) - Surface Pain [ Time Frame: Baseline to Termination Visit ]Within-subject change in neuropathic pain using the Neuropathic Pain Scale (NPS) with surface pain where 0=no surface pain and 10=most intense surface pain imaginable.
- Change From Baseline in Average Pain Interference With Sleep (11-point Likert Scale) [ Time Frame: Baseline to end of entire treatment phase visit ]Change from Baseline in average pain interference with sleep (11-point Likert scale) where 0=no interference with sleep and 10=worst possible interference with sleep.
- Change From Baseline in Average Pain Interference With Activity (11-point Likert Scale) [ Time Frame: Baseline to end of entire treatment phase visit ]Change from Baseline in average pain interference with activity (11-point Likert scale) where 0=no interfence with activity and 10=worst possible interference with activity.
- Change From Baseline in Quality of Life Using the SF-36 Health Survey - Physical Component Summary (PCS) [ Time Frame: Baseline to Termination Visit ]Change from Baseline in quality of life using the SF-36 Health Survey - Physical Component Summary (PCS). Values range from 0 to 100 with high values indicating a good condition. Positive change in baseline values indicate improvement in quality of life.
- Change From Baseline in Quality of Life Using the SF-36 Health Survey - Mental Component Summary (MCS) [ Time Frame: Baseline to Termination Visit ]Change from Baseline in quality of life using the SF-36 Health Survey - Mental Component Summary (MCS). Values range from 0 to 100 with high values indicating a good condition. Positive change in baseline values indicate improvement in quality of life.
