Brief summary

Open-label safety study of oral olanzapine treatment in adolescents, aged 13 to 17 years, with bipolar I disorder (manic or mixed episodes) or schizophrenia.

Interventions

DRUGOlanzapine

2.5 milligrams (mg) to 20 mg given orally, daily for 52 weeks

BEHAVIORALStandard behavioral weight intervention

One time counseling and basic counseling information on healthy eating and exercise habits at randomization visit only.

BEHAVIORALIntense behavioral weight intervention

Counseling provided at randomization and at all subsequent study visits by appropriately trained individual regarding healthy lifestyle habits. Participants also provided with simple tools to help enable healthy eating and exercise habits.
