Invega (Paliperidone) for the Treatment of Mania in Children and Adolescents Ages 6-17 With Bipolar Disorder
This will be an 8-week open-label trial, using daily doses of paliperidone (Invega) in the treatment of children and adolescents who meet DSM-IV criteria of Bipolar I, Bipolar II, or Bipolar Spectrum Disorder. Specific hypotheses are as follows:
Hypothesis 1: Bipolar Disorder symptomatology in children and adolescents with DSM-IV Bipolar I, Bipolar II, or Bipolar Spectrum Disorder will be responsive to Invega treatment.
Hypothesis 2: Invega -associated improvement in bipolar disorder symptomatology in children and adolescents will translate into improved functional capacities (neuropsychological, social, and occupational), as well as an increased quality of life throughout treatment.
Hypothesis 2: Invega treatment will be safe and well tolerated as reflected by a low drop out rate and absence of major side effects.

- Change in Symptoms Measured by Young Mania Rating Scale (YMRS) [ Time Frame: Baseline and 8 weeks (or final study visit, if subjects completed the study before 8 weeks) ]The YMRS is an 11-item instrument used to assess the severity of mania in patients with a diagnosis of bipolar disorder. Four items are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven itemsare graded on a 0 to 4 scale. The maximum possible total score is 60 (worse outcome, severe symptoms), and the minimum possible total score is 0 (no symptoms).
- Change in Symptoms Measured by DSM-IV Mania Symptoms Checklist [ Time Frame: Baseline and 8 weeks (or final study visit, if subjects completed the study before 8 weeks) ]A 13-item clinician-rated symptom checklist developed by Massachusetts General Hospital to measure symptoms of mania. Each item is given a rating for frequency (1=less than 4 days, 2=greater than or equal to 4 days, 3=daily) and intensity (1=mild, 2=moderate, 3=severe), which are combined to yield a composite severity score ranging from 0 (least severe) to 3 (most severe). The composite severity scores from all 13 items are summed to yield a total measure score, with a minimum score of 0 (least severe) and a maximum score of 39 (most severe).

Other Name: Invega
Invega (paliperidone), a second generation antipsychotic (SGA), is a psychotropic agent belonging to the chemical class of benzisoxazole derivatives. Invega is approved by the FDA for the treatment of schizophrenia in adults. Initial data suggest a promising role for Invega in the treatment of bipolar disorder with minimal adverse events of weight gain. We propose to study the safety and efficacy of Invega therapy in children and adolescents with Bipolar I, Bipolar II, and Bipolar Spectrum Disorder. The study results will be used to generate hypotheses for a larger, randomized, controlled clinical trial with explicit hypotheses and sufficient statistical power.
The proposed study includes 1) use of a 8-week design to document the response rate, 2) assessment of the impact of Invega on functional capacities (quality of life, psychosocial function) and cognition, and 3) careful assessment of safety and tolerability.
