Brief Summary

Chemotherapy induced nausea and vomiting (CINV) is one of the most distressing toxicities of cancer treatment. It can occur up to 90% in case of highly emetogenic chemotherapy (HEC) use. It is important to effectively manage CINV for a number of reasons. Acute phase vomiting can lead to vomiting in the delayed phase. It causes poor compliance with further therapy. Quality of life is compromised. It is easier to prevent nausea/vomiting than to treat it. Though strategies for prevention of CINV have been improved, it is still a significant problem. Newer drugs were explored and studied. The complete response rates were further increased with usage of olanzapine, an FDA approved antipsychotic, which blocks multiple neurotransmitters in the central nervous system.

Olanzapine has been studied in multiple randomized trials in adults for its safety and efficacy in prevention of CINV. Various RCTs have demonstrated the superiority of olanzapine for prevention of CINV in patients receiving highly and moderately emetogenic chemotherapy. Olanzapine has been approved for prevention of CINV in adults.

Unfortunately there are no large randomized trials demonstrating the efficacy of olanzapine for CINV prevention in children receiving HEC. The positive experience with olanzapine reported in adult oncology patients has prompted some pediatric clinicians to prescribe olanzapine for individual children receiving chemotherapy. Olanzapine is frequently used for the treatment of schizophrenia and bipolar disorder in children and adolescents. Though various studies have demonstrated safety of olanzapine in children, data regarding the efficacy of olanzapine in children and adolescents for prevention of CINV is limited. There are many small studies describing the safety and efficacy of olanzapine for prevention of CINV. However, there are no large randomized trials. Olanzapine is available in generic form and is not an expensive drug. Therefore we would like to conduct a randomized trial to look for the efficacy of olanzapine in pediatric population for prevention of CINV

Detailed Description

Children and adolescents registered with confirmed diagnosis of cancer will be assessed for eligibility criteria and enrolled in the study. Subjects will be randomized into study and control groups using table of random numbers generated by computer. Sequentially numbered, opaque, sealed envelopes will be used for concealed allocation. After randomization, subjects will be interviewed 1 hour prior 1st dose of chemotherapy. Subjects will receive the antiemetic drugs for four days as per the allotted arm. All doses will be administered under supervision and 30 minutes before chemotherapy. The data will be collected from each patient from day 1 to day5 from the last dose of chemotherapy. The details will contain different items dealing with demographic and clinical characteristic of the subjects. A Diary will be maintained for nausea and vomiting episodes. It will help in collecting data regarding nausea, vomiting along with some additional variables like chemotherapy related toxicities, requirement of any rescue medication. The subjects will be given the diary for symptom assessment on day 1 and it will be filled up under the supervision of the investigator on day 1 till completion of chemotherapy. The diary will be given to the subjects following the completion of chemotherapy to record all the events (incidence and severity of nausea, vomiting, requirement of rescue medication and other toxicities ) and will be contacted by phone or in person by the investigator. Edmonton's symptom assessment criterion will be used in the diary for assessing severity of nausea. The NCI's CTCAEv4.03 criterion will be used to assess the severity of vomiting and adverse events based on the data provided by the patient in the diary. Patients/attendants will be explained about the filling of the diary and will maintain it for recording of vomiting. A modified intention-to-treat population will be used for efficacy analysis. Proportion of patients with CR during acute phase, delayed phase and overall period will be compared between the two arms.
