A Multiple Dose Pharmacokinetic Study of Perampanel in Korean Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
This study will consist of 2 phases: Pretreatment Phase and Treatment Phase. The Pretreatment Phase will have 2 time points: Screening and Baseline. Subjects will be admitted to the clinical study ward the day before starting the study drug administration (Day -1) for PK and safety assessments during Treatment Phase, and discharged at Day 33 (group A) and Day 47 (group B). Post-test will be done at Day 37 (+/-1), Day 42 (+3) (group A) and Day 51 (+/-1), Day 56 (+3) (group B). Study medication will be administered with 240 mL of room temperature water

No sperm donation is allowed during the study period and for 30 days after study drug discontinuation Provide written informed consent Willing and able to comply with all aspects of the protocol Exclusion Criteria Subjects who meet any of the following criteria will be excluded from participation in the study: Clinically significant illness that requires medical treatment within 8 weeks or a clinically significant infection that requires medical treatment within 4 weeks of dosing Evidence of disease that may influence the outcome of the study within 4 weeks prior to dosing; e.g., psychiatric disorders and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system, or subjects who have a congenital abnormality in metabolism Any history of gastrointestinal surgery that may affect PK profiles of perampanel, e.g., hepatectomy, nephrotomy, digestive organ resection at Screening and Baseline Evidence of clinically significant organ dysfunction or any clinically significant deviation from normal in physical examination, vital signs, ECG, or clinical laboratory determinations. Subjects whose liver enzyme values are outside of the acceptable normal limits will be excluded A prolonged QT/QTc interval (QTc greater than 450 ms) demonstrated on ECG at Screening or Baseline Any suicidal ideation with intent with or without a plan at Screening or within 6 months of Screening Any lifetime suicidal behavior Known history of clinically significant drug allergy at Screening and Baseline Known history of food allergies or presently experiencing significant seasonal or perennial allergy at Screening and Baseline Known to be human immunodeficiency virus (HIV) positive at Screening Active viral hepatitis (A, B or C) as demonstrated by positive serology at Screening History of drug or alcohol dependency or abuse within the 2 years prior to Screening, or those who have a positive urine drug test or breath (or urine) alcohol test at Screening or Baseline Intake of caffeinated beverages or food within 72 hours prior to dosing Intake of nutritional supplements, juice, and herbal preparations or other foods or beverages that may affect CYP (e.g., alcohol, grapefruit, grapefruit juice, grapefruit-containing beverages, apple or orange juice, vegetables from the mustard green family [e.g., kale, broccoli, watercress, collard greens, kohlrabi, brussel sprouts, mustard], and charbroiled meats) within 1 week prior to dosing Intake of herbal preparations containing St. John's Wort within 4 weeks prior to dosing Use of prescription drugs within 4 weeks prior to dosing Intake of over-the-counter (OTC) medications within 2 weeks prior to dosing Currently enrolled in another clinical trial or used any investigational drug or device within 30 days or 5x the half-life, whichever is longer preceding informed consent Receipt of blood products within 4 weeks, or donation of blood within 8 weeks, or donation of plasma within one week of dosing Engagement in strenuous exercise within 2 weeks prior to check-in (e.g., marathon runners, weight lifters, etc.)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics (PK) of perampanel in Korean healthy male subjects | PK analysis will be performed on PK Analysis Set using plasma concentrations of perampanel. Plasma concentrations will be tabulated by nominal sampling time and summarized using summary statistics. | Approximately 56 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and tolerability of perampanel | Safety will be assessed by monitoring and recording all adverse events (AEs) and serious adverse events (SAEs), regular monitoring of hematology, blood chemistry and urine values, regular measurement of vital signs, weight, physical examinations and electrocardiograms (ECGs). | Approximately 56 days |
