  Description
Painful Diabetic Neuropathy (PDN): Prior Treatment of Placebo All subjects in this study received open-label perampanel, up-titrated in 2-mg increments from 2 mg/day to 12 mg/day. Subjects took 1 to 4 tablets orally once daily (QD), depending upon the subject's dose at that time. All subjects in this study previously completed a double-blind, placebo-controlled studies for PDN or PHN.
PDN: Prior Treatment of Perampanel All subjects in this study received open-label perampanel, up-titrated in 2-mg increments from 2 mg/day to 12 mg/day. Subjects took 1 to 4 tablets orally QD, depending upon the subject's dose at that time. All subjects in this study previously completed a double-blind, placebo-controlled studies for PDN or PHN.
Post Herpetic Neuralgia (PHN): Prior Treatment of Placebo All subjects in this study received open-label perampanel, up-titrated in 2-mg increments from 2 mg/day to 12 mg/day. Subjects took 1 to 4 tablets orally QD, depending upon the subject's dose at that time. All subjects in this study previously completed a double-blind, placebo-controlled studies for PDN or PHN.
PHN: Prior Treatment of Perampanel All subjects in this study received open-label perampanel, up-titrated in 2-mg increments from 2 mg/day to 12 mg/day. Subjects took 1 to 4 tablets orally QD, depending upon the subject's dose at that time. All subjects in this study previously completed a double-blind, placebo-controlled studies for PDN or PHN.
