简要总结

RATIONALE: PTC299 may stop the growth of tumor cells by blocking blood flow to the tumor.

PURPOSE: This phase I trial is studying the side effects and the best dose of PTC299 in treating young patients with recurrent or refractory primary central nervous system tumors.

详细描述

OBJECTIVES:

Primary

  • To estimate the maximum-tolerated dose and the recommended phase II dose of VEGF inhibitor PTC299 (PTC299) in pediatric patients with recurrent or progressive primary central nervous system (CNS) tumors.
  • To evaluate and characterize the adverse events associated with this regimen in these patients.
  • To evaluate and characterize the pharmacokinetics and pharmacodynamics of this regimen in these patients.

Secondary

  • To investigate the relationships between PTC299 plasma exposure and other outcomes measures.
  • To evaluate the antitumor activity of this regimen in these patients.
  • To evaluate changes in angiogenic and inflammatory markers in the blood and the relationship between these changes and other outcome measures.
  • To obtain preliminary evidence of biologic activity of PTC299 by using magnetic resonance diffusion to assess tumor cellularity.
