Study to Evaluate the Effect of Aprepitant in Children and Adolescents Receiving AML Remission Induction Chemotherapy


Brief description of study

The purpose of the study is to find out the efficacy of an anti-emetic drug, Aprepitant as an add-on therapy to prevent vomiting in children and adolescents receiving chemotherapy for leukemia (AML).

Children and adolescents admitted with confirmed diagnosis of AML will be assessed for eligibility criteria and enrolled in the study. Then they will be divided (randomized) into experimental and control groups.

Experimental group will receive Aprepitant capsules 1 h prior to chemotherapy on days 1-3 in addition to ondansetron. Patients will be required to swallow the whole capsule and opening of capsule will not be permitted. All three doses will be administered under supervision.

Control group will receive ondansetron (0.15 mg/kg) as an intravenous bolus 30 minutes before chemotherapy followed by every 8 hourly for 8 days. Metoclopramide will be used as a rescue agent.

The data will be collected from each patient in a proforma from day 1 to day 13 of chemotherapy. A Diary will be maintained for nausea and vomiting record.

Edmonton's symptom assessment criterion will be used in the diary for assessing severity of nausea. The NCI guidelines will be used to assess the severity of vomiting based on the data provided by the patient in the diary.

A modified intention-to-treat population (patients who receive chemotherapy, take one or more doses of study drug, and have one or more post treatment measurements) will be used for efficacy analysis. Proportion of patients with complete response will be compared between patients with or without aprepitant.

Detailed Study Description

Children and adolescents admitted with confirmed diagnosis of AML will be assessed for eligibility criteria and enrolled in the study. Subjects will be randomized into experimental and control groups using table of random numbers generated by computer.Experimental group will receive aprepitant capsules as an add-on therapy (Apretero; Hetero Laboratories, India) 1 h prior to chemotherapy on days 1-3 in addition to ondansetron.

The dose of aprepitant will be as per our previous study based on weight groups'

  • Weight 15-40 kg : Aprepitant 80 mg on days 1-3
  • Weight > 41kg: Aprepitant 125 mg on day 1 followed by 80 mg on days 2-3 Patients will be required to swallow the whole capsule and opening of capsule will not be permitted.

All three doses will be administered under supervision by the sister allocated. Control group will receive ondansetron (0.15 mg/kg) as an intravenous bolus 30 minutes before chemotherapy followed by every 8 hourly. Metoclopramide will be used as a rescue agent.

The data will be collected from each patient in a proforma from day 1 to day 13 of chemotherapy by the investigator during his/her stay as in-patient in the hospital. The Proforma will contain different items dealing with demographic and clinical characteristic of the subjects.A Diary will be maintained for nausea and vomiting record. It will help in collecting data regarding nausea, vomiting along with some additional variables likechemotherapy 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 and day 2 of chemotherapy. The diary will be given to the subjects on day 3 of the chemotherapy to record all the events (incidence and severity of nausea, vomiting, requirement of rescue medication and other toxicities).

Edmonton's symptom assessment criterion will be used in the diary for assessing severity of nausea. The NCI guidelines will be used to assess the severity of vomiting based on the data provided by the patient in the diary.Patients/attendant's will be explained about the filling of the diary and will maintain it for recording of vomiting under the investigator's supervision.

A modified intention-to-treat population (patients who receive chemotherapy, take one or more doses of study drug, and have one or more post treatment measurements) will be used for efficacy analysis.Proportion of patients with CR will be compared between patients with or without aprepitant.
