Lamotrigine for the Treatment of Mania in Youth Ages 6-17 With Bipolar Disorder
The main objective of this study is to assess the effectiveness and safety of lamotrigine in the treatment of youth with bipolar and bipolar spectrum disorder. This is an exploratory, 12-week, open-label treatment period, pilot study, of youth ages 6-17, who meet the DSM-IV diagnostic criteria for bipolar I, bipolar II, or bipolar spectrum disorder. The study results will be used to generate hypotheses for a larger randomized controlled clinical trial. Based on the available literature in adults with bipolar disorder, we hypothesized that lamotrigine will be efficacious and well tolerated in youth with pediatric bipolar and bipolar spectrum disorders.

|Official Title:||A Pilot Open Study of the Safety and Effectiveness of Lamotrigine for the Treatment of Mania in Youth Ages 6-17 With Bipolar I, Bipolar II, and Bipolar Spectrum Disorders|
- Change of Mania Symptoms Assessed by Young Mania Rating Scale (YMRS) [ Time Frame: baseline to 12 weeks ] [ Designated as safety issue: No ]Mean reduction in YMRS score at endpoint/LOCF. This is a scale to measure symptoms of mania in children and adolescents. 11 items are rated from 0-4 (7 items) or 0-8 (4 items). The minimum (least severe) total score is 0, and maximum (most severe) total score is 60.

Open-label, flexible-dose, BID treatment of lamotrigine (Lamictal). For children <12 years, dosing began at 0.35 mg/kg/day, divided in 2 doses, rounded down to nearest 5mg, to be increased weekly depending on response and tolerability to maintenance dose of 5-15 mg/kg/day (maximum 400 mg/day in 2 divided doses). For children ≥12 years, dose began at 25 mg/day in 1 dose, to be increased weekly depending on response and tolerability to maintenance dose of 300-500 mg/day in 2 divided doses.
Other Name: Lamictal
Lamotrigine is a new generation antiepileptic drug, approved by the FDA in 2003 for the maintenance treatment of adults with Bipolar I disorder to delay the time to occurrence of mood episodes (depression, mania, hypomania,& mixed episodes) in patients treated for acute mood episodes with standard therapy. Recent studies have shown that Lamotrigine maintenance treatment was more robust in bipolar depression.
The study includes 1) use of a 12-week design to document the response rate 2) assessment of the impact of Lamotrigine on functional capacities and cognition, 3) careful assessment of safety and tolerability.
