Pharmacokinetics Study of Oral 2-Deoxy-D-Glucose (2DG) in Subjects With a Confirmed Diagnosis of Epilepsy

The study will be conducted as a 1-day Monitored Dosing and Pharmacokinetics Period in an inpatient setting. Subjects will report to the hospital in a fasted state (since midnight) on the morning of the pharmacokinetics study. Subjects will continue to fast until one hour after the 2DG dose has been given. 2DG will be given as either a single oral dose (40 mg for Dose Level 1; 60 mg for dose level 2) or 60 mg bid (Dose Level 3). Blood for pharmacokinetic analysis will be drawn at time 0 (prior to drug administration), and then at 15, 30, 45, and 60 minutes and at 2, 4, 6, 12, and 24 hours after single dose 2DG administration. Blood for pharmacokinetic analysis will be drawn at time 0 (prior to drug administration) and then at 15, 30, 45, and 60 minutes and at 2, 4, 6, 12, and 24 hours after the last dose for Dose Level 3. Patients will be closely monitored for safety during and following dosing with 2DG.
