Olanzapine/Fluoxetine Combination in Children and Adolescents With Bipolar I Depression: A Randomized, Double-Blind, Placebo-Controlled Trial
Bibliographic record
Abstract
OBJECTIVE: To assess the efficacy and safety of olanzapine/fluoxetine combination (OFC) for the acute treatment of bipolar depression in children and adolescents. METHOD: Patients 10 to 17 years of age with bipolar I disorder (BP-I), depressed episode, baseline Children's Depression Rating Scale-Revised (CDRS-R) total score ≥40, Young Mania Rating Scale (YMRS) total score ≤15, and YMRS-item 1 ≤2 were randomized to OFC (6/25-12/50 mg/day olanzapine/fluoxetine; n = 170) or placebo (n = 85) for up to 8 weeks of double-blind treatment. The primary efficacy measure was mean change in CDRS-R using mixed-model repeated-measures methodology. RESULTS: Baseline-to-week-8 least-squares mean change in CDRS-R total score was greater for OFC-treated patients than for placebo-treated patients (-28.4 versus -23.4, p = .003; effect size = .46), with between-group differences statistically significant at week 1 (p = .02) and all subsequent visits (all p < .01). Rates of and times to response and remission were statistically significantly greater for OFC- than for placebo-treated patients. The most frequent treatment-emergent adverse events in the OFC group were weight gain, increased appetite, and somnolence. Mean weight gain at patient's endpoint was significantly greater for OFC- than for placebo-treated patients (4.4 kg versus 0.5 kg, p < .001). Treatment-emergent hyperlipidemia was very common among OFC-treated patients. Abnormal increases in hepatic analytes, prolactin, and corrected QT interval (QTc) were also common or very common but generally not clinically significant. CONCLUSION: In this study, OFC was superior to placebo, and has been approved by the US Food and Drug Administration (FDA) for the acute treatment of bipolar I depression in patients 10 to 17 years of age. Benefits should be weighed against the risk of adverse events, particularly weight gain and hyperlipidemia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
