This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.This is a pediatric phase I trial of CC-5013 performed in children with recurrent or refractory brain tumors, to determine the MTD and safety profile of CC-5013. CC-5013 will be given orally once a day for 21 days of a 28-day course. It is similar to thalidomide and has a wide variety of pharmacologic, antiangiogenic and immunologic effects. Courses may continue for two years provided the subject does not develop unacceptable toxicity or disease progression. The objectives of this study are:To estimate the MTD of oral CC-5013 administered to children with recurrent or refractory primary CNS tumors once daily for 21 days of a 28 day courseTo describe the toxicity profile and define the dose-limiting toxicity of CC-5013 in children with recurrent or refractory primary CNS tumorsTo characterize the pharmacokinetics of CC-5013 in children and adolescentsTo evaluate changes in circulating endothelial cells (CECs) and circulating endothelial cell precursors (CEPs) in patients treated with CC-5013, and to investigate the correlation between changes in CECs and CEPs, plasma, serum and urine levels of proteins associated with angiogenesis including thrombospondin, b-FGF, TNF- , IL-12, IL-8 and VEGF, and correlate these changes with changes in MR perfusion and clinical outcome To evaluate changes in MR spectroscopy, MR perfusion and diffusion during treatment.
