What was measured

Topotecan plasma concentration-time data are collected on day 1 of consolidation cycle 1 after a single IV dose. Individual estimates of topotecan clearance are obtained using post hoc analysis.

Analysis population: Eligible patients who received intravenous topotecan during consolidation cycle 1 and had PK samples collected were included in this analysis. Per protocol, low- and intermediate-risk patients did not receive topotecan during consolidation unless they experienced disease progression during induction. One such intermediate-risk patient was included.

Groups in this outcome

Intermediate-Risk Group

Patients with no evidence of metastatic disease (M0) medulloblastoma or nodular desmoplastic histology with less than a gross total resection (GTR), other histologic diagnoses with no metastatic disease

High-Risk Group

Patients with central nervous system (CNS) metastatic disease
