Perampanel doses will be up-titrated in 2 mg steps at minimum weekly intervals starting at 2 mg daily and up-titrated to 12 mg daily (taken orally).
Other Name: Perampanel
- Mean Change From Baseline in Short Form-McGill Pain Questionnaire (SF-MPQ): Sensory and Affective Scores, From Baseline to Week 48. [ Time Frame: Baseline and Week 48 ]Mean change from baseline to open-label study endpoint and other study visits in SF-MPQ scores sensory and affective). SF-MPQ was completed to assess intensity of pain over the past 48 days for all 15 descriptors: throbbing, shooting, stabbing, sharp, cramping, gnawing, hot-burning, aching, heavy, tender, splitting,tiring-exhausting, sickening, fear-causing, punishing-cruel. Each descriptor was scored by participant on a 4-point intensity scale (0=none to 3=severe) and totaled in each subclass (sensory range 0-45); higher scores indicated higher intensity of pain.
- Mean Change From Baseline in SF-MPQ Visual Analog Scale (VAS): From Baseline to Week 48. [ Time Frame: Baseline and Week 48 ]SF-MPQ VAS consists of a line 0 to 100 millimeters (mm) in length; range is 0 (no pain) to 100 mm (worst possible pain). Subjects placed a mark indicating the intensity of their pain. Distance from left-hand end of line was measured and entered on Case Report Form (CRF) as score in mm. Higher score indicates greater level of pain.
- Mean Change From Baseline in SF-MPQ Current Pain Intensity (CPI): From Baseline to Week 48 [ Time Frame: Baseline and Week 48 ]Mean change from baseline in SF-MPQ (CPI) at study endpoint. Affective score ranges from 0-5. Higher scores indicate more severe pain (0=no pain, 1=mild, 2=discomforting, 3=distressing, 4=horrible, 5=excrutiating).
- Analysis of Patient Global Impression of Change (PGIC) at Week 48/End of Treatment (EOT) [ Time Frame: Baseline and Week 48 ]The PGIC asked subjects to evaluate the change in their overall status compared with the start of open-label treatment on a scale ranging from 1 (very much improved) to 7 (very much worse). [Please note high withdrawl rate during study].
- Mean Change From Baseline in Short Form 36 Item (SF-36) Health Survey: Physical and Mental Component Scores From Baseline to Week 48/EOT [ Time Frame: Baseline and Week 48 ]Mean change from baseline in SF-36 Item Health Survey Scores at study endpoint. Each component on the SF-36 Item Health Survey is scored from 0-100 with higher scores reflecting better subject status.
