Group E: End-stage renal disease
Subjects who have normal renal function (CLcr >80 mL/min/1.73 m^2). Subjects will be orally administered Levetiracetam (LEV) 500 mg once. After LEV administration, safety assessments and blood and urine samplings will be taken through to Day 4 during the Treatment Period, and safety follow-up assessments will be performed on Day 8 according to the schedule of study assessments. Blood samples for Pharmacokinetics (PK): Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 hours postdose Urine samples for PK: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72 hours postdose
Patients who have mild renal impairment (50<CLcr <80 mL/min/1.73 m^2). Subjects will be orally administered (Levetiracetam) LEV 500 mg once. After LEV administration, safety assessments and blood and urine samplings will be conducted through Day 5 during the Treatment Period, and safety follow-up assessments will be performed on Day 8 according to the schedule of study assessments. Blood samples for Pharmacokinetics (PK): Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96 hours postdose Urine samples for PK: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72, 72 - 96 hours postdose
Patients who have moderate renal impairment (30<CLcr < 50 mL/min/1.73 m^2). Subjects will be orally administered Levetiracetam (LEV) 250 mg once. After LEV administration, safety assessments and blood and urine samplings will be conducted through Day 6 during the Treatment Period, and safety follow-up assessments will be performed on Day 8 according to the schedule of study assessments. Blood samples for Pharmacokinetics (PK): Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours postdose Urine samples for PK: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72, 72 - 96, 96 -120 hours postdose
Patients who have severe renal impairment (CLcr <30 mL/min/1.73 m^2). Subjects will be orally administered Levetiracetam (LEV) 250 mg once. After LEV administration, safety assessments and blood and urine samplings will be conducted through Day 7 during the Treatment Period, and safety follow-up assessments will be performed on Day 8 according to the schedule of study assessments. Blood samples for Pharmacokinetics (PK): Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144 hours postdose Urine samples for PK: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72, 72 - 96, 96 -120, 120 - 144 hours postdose
Group E will receive Levetiracetam (LEV) 500 mg on Day 1, 44 hours (h) before the first hemodialysis. As a supplementary dose LEV 250 mg will be administered 1 h after the end of the first hemodialysis on Day 3. The 4-h Hemodialysis are scheduled as follows: Dialysis: 44 h to 48 h after the first dose (Day 3) Dialysis: 92 h to 96 h after the first dose (Day 5) Dialysis: 140 h after the first dose (Day 7) Safety assessments and blood samplings will be conducted until Day 7. Safety follow-up assessments will be performed on Day 10. Blood samples for Pharmacokinetics (PK): Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 30, 44*, 44.25*, 44.5*, 45*, 46*, 47*, 48*, 49, 49.5, 50, 51, 53, 55, 57, 61, 73, 92, 96, 120, 140 hours post first dosing. 49 h-sample should be taken before the additional dose. The 44 h, 92 h, and 140 h sample should be taken before the start of the hemodialysis. *Inflow blood, outflow blood, and dialysate fluid will be collected.
