Trial overview
Official title: An Open-Label, Uncontrolled, Long-Term Study to Assess the Safety of LAMICTAL in Pediatric Subjects Previously Enrolled in Protocol LAM20006 and In LAMICTAL-naive subjects (1-24 months of age)
Trial description: This study will evaluate the long-term safety of LAMICTAL(lamotrigine)in subjects with partial seizures previously enrolled in protocol LAM20006 and in subjects 1-24 months of age who have never received LAMICTAL(LAMICTAL-naive). For LAMICTAL-naive subjects, LAMICTAL will be added to the subject's current epilepsy medications.
