Brief summary

The main goal of this study is to help answer the following research question(s) and not to treat the child's illness. * Can this study drug make children with bipolar depression feel better? * Does this study drug work better than a placebo (sugar pill)? * Does this study drug cause side effects in children who take it? * Is this drug safe to use in children? (The study drug is a mixture of olanzapine and fluoxetine)

Interventions

Change From Baseline in the Children's Depression Rating Scale Revised (CDRS-R) Total Score at Week 8Baseline, Week 8CDRS-R Total score measures the presence and severity of depression in children. The scale consists of 17 items scored on a 1-to-5- or 1-to-7-point scale. A rating of 1 indicates normal functioning. Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. Least Square (LS) mean was adjusted for baseline, country, treatment, visit, and treatment times (\*) visit interaction.

Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. Least Square (LS) mean was adjusted for baseline, country, treatment, visit, and treatment times (\*) visit interaction.

CDRS-R is a 17-item scale measuring presence/severity of depression in children and is scored on a 1-to-5- or 1-to-7-point scale. Rating of 1 indicates normal function. Scores range: 17 to 113. Scores \<20 indicate an absence of depression, scores 20 to 30 indicate borderline depression, scores 40 to 60 indicate moderate depression. The YMRS is an 11-item scale measuring severity of manic episodes; 4 items are rated on a scale from 0 (symptoms not present) to 8 (symptom extremely severe) with remaining items rated on a scale from 0 (symptoms not present) to 4 (symptom extremely severe). YMRS score ranges from 0 to 60. CGI-BP measures participant's overall severity of bipolar symptoms. Scores range: 1 (normal, not at all ill ) to 7 (among the most extremely ill participants).

Time frame: Baseline up to Week 8

Population: Population analyzed was the M-ITT Population: all randomized participants who took at least 1 dose of study drug and excluding participants from 2 GCP noncompliant sites and who had both the CDRS-R, YMRS and CGI-BP total scores at baseline and at least 1 post-baseline measurement; Last Observation Carried Forward (LOCF)

Percentage of Participants With Response Up to Week 8

Response is defined as a CDRS-R total score greater than or equal to (≥)50% reduction from baseline and YMRS elevated mood score ≤2. CDRS-R Total score measure the presence and severity of depression in children. The scale consists of 17 items scored on a 1-to-5- or 1-to-7-point scale. Rating of 1 indicates normal function. Scores range: 17 to 113. In general, \<20 indicate an absence of depression, scores 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. YMRS is an 11-item scale that measures the severity of manic episodes. Four items are rated on a scale from 0 (symptoms not present) to 8 (symptom extremely severe). The remaining items are rated on a scale from 0 (symptoms not present) to 4 (symptom extremely severe). The YMRS total score ranges from 0 to 60.

Percentage of Participants With at Least One Treatment-Emergent Incident of Dyskinesia Up to Week 8

Dyskinesia was measured using the Abnormal Involuntary Movement Scale (AIMS) a 12-item scale designed to record the occurrence of dyskinetic movements. Items 1 through 10 are rated on a 5-point scale: 0 (no dyskinetic movements) to 4 (severe dyskinetic movements). Items 11 and 12 are yes/no questions regarding the dental condition of a patient. Total score (0-40) is obtained by adding the scores of the first 10 items. An abnormal result is defined as having a score ≥3 for at least 1 of the first 7 items or a score ≥2 for at least two of the first 7 items.
