Summary
This is a multi-center, uncontrolled, open-label study conducted in Japan and South Korea to
evaluate the efficacy and safety of lamotrigine monotherapy in subjects with newly diagnosed
epilepsy and those with recurrent epilepsy (currently untreated).
The study is composed of baseline, escalation phase, maintenance phase, taper phase and post
study examination. During the escalation phase, the investigational product is administered
orally at 25 mg/day for 2 weeks, then 50 mg/day for 2 weeks and finally 100 mg/day for 2
weeks. During the maintenance phase, 200 mg/day is administered orally for 24 weeks. However,
the dose can be decreased to 100 mg/day if there are safety concerns. Also, if it is
confirmed that the seizures cannot be controlled at the dose of 200 mg/day, the dose can be
gradually increased up to 400 mg/day by 50-100 mg/day at intervals of at least 1 week. As a
rule, lamotrigine should be administered once daily (in the evening), but the dose exceeding
200 mg/day can be administered in two divided doses (in the morning and evening). After the
completion of maintenance phase, Japanese subjects who have responded to lamotrigine without
tolerability issues are eligible to enter an extension phase of the study if indicated, until
either approval of this indication (monotherapy in epilepsy) or after 24 months after LSLV
(Last Subject's Last Visit) of the maintenance phase, whichever is sooner.
