What was measured

4-OH cyclophosphamide plasma concentration-time data are collected on day 1 of maintenance cycle A1. Individual estimates of 4-OH cyclophosphamide AUC0-24h (area under concentration curve from time 0 to 24 hours post-dose) are obtained using post hoc analysis.

Analysis population: Eligible patients who received cyclophosphamide during maintenance cycle A1 and had samples collected for PK analysis.

Groups in this outcome

Low-Risk Group

Patients with gross total resection (GTR)/no evidence of metastatic disease (M0) medulloblastoma, nodular desmoplastic histology, or high grade glioma

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
