A Phase II Study of Topotecan in Children With Recurrent Wilms Tumor
Topotecan administered intravenously over 30 minutes daily for 5 consecutive days for 2
consecutive weeks, with a two-day rest given in between the five-day treatment blocks. The
topotecan dose started at 1.8 mg/m2/dosage and adjusted to attain a target systemic exposure
of 80 plus or minus 10 ng-hr/ml.each cycle consists of 28 days and subsequent cycles can be
administered upon hematological recovery. Patients with a CR, PR, or SD, can continue to
receive up to a total of six cycles. Patients with PD are removed from the study.
Secondary Objectives include:
- To describe the anti-tumor activity of topotecan in children with recurrent Wilms tumor
of anaplastic histology.
- To assess the relation between CYP3A4/5 genotype and the pharmacokinetics and
pharmacodynamics of topotecan.
- To assess the relation between ABCG2 genotype and the pharmacokinetics and
pharmacodynamics of topotecan.
