Olanzapine for Chemotherapy-Induced Vomiting in Children

This study is testing if adding olanzapine to standard anti-nausea medications can better control vomiting caused by chemotherapy in children. Many children receiving strong chemotherapy (highly emetogenic chemotherapy, HEC) still experience vomiting despite current treatments. Olanzapine has helped adults with similar issues and has been used safely in children for other conditions. This trial will compare olanzapine to a placebo (an inactive pill that looks like olanzapine) in about 200 children aged 30 months to 18 years who are receiving HEC. The main goal is to see if olanzapine improves vomiting control during the first 8 days of chemotherapy. The study's current status is unclear.
