What was measured

Volume of distribution at steady state (Vss) of sorefenib administered orally as tablets, BID approximately every 12 hours for cycles of 28 days with no rest period between cycles to children with refractory solid tumors, leukemia, or AML and FLT3-ITD mutation.

Analysis population: Data was and never will be collected

Groups in this outcome

STRATUM I (REFRACTORY SOLID TUMOR

Patients receive oral sorafenib twice daily on days 1-28. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of sorafenib until the maximum-tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity (DLT). Once the MTD is determined, up to 6 additional patients under 12 years of age may be treated at the MTD. The MTD dose level is also expanded to enroll up to 6 patients with refractory leukemia.

STRATUM II (REFRACTORY LEUKEMIA)

A cohort of 3-6 patients with leukemia receives treatment as in stratum 1 at the MTD determined in stratum 1. If 2 of 3 or 2 of 6 patients experience a DLT at the solid tumor MTD, sorafenib is reduced by one dose level. The leukemia MTD is defined as the dose at which \< 1/3 of patients experience DLT during course 1 of treatment

STRATUM III (ACUTE MYELOID LEUKEMIA AND FLT3-ITD MUTATION)

Patients receive sorafenib as in stratum 1 at the MTD determined in stratum 2. Patients undergo blood sample collection for pharmacokinetics, pharmacodynamics (in leukemia blasts only), circulating endothelial cells (CEC), circulating CEC precursors (CECP), VEGF and VEGF-2 , gene expression, proteomic profile, ERK phosphorylation, and FLT3 phosphorylation activity. Tumor tissue samples may also be analyzed for the presence of ras, raf, or FLT3.
