|Refractory Brain Tumors||Drug: Busulfan||Phase 1|
Pediatric brain tumors remain among the most common malignancies in childhood, second only to leukemia, representing 20% of all childhood cancers in the United States (1). Although significant strides have been made in therapies for other pediatric malignancies, mortality for patients with brain tumors remains high. The mainstay of therapy for CNS tumors has been a combination of surgery, chemotherapy, and radiation. High dose chemotherapy with stem cell transplant has been proposed as an alternative to radiation, in very young children and for relapsed patients. Stem cell transplantation however is not without significant side effects as well as transplant related mortality.
Busulfan is an alkylating agent and is able to exert its cytotoxic effects through hydrolysis and subsequent production of carbonium ions, directly alkylating DNA, interfering with its replication, and ultimately leading to cell death (2). Busulfan readily crosses the blood barrier, allowing for CNS levels nearly equal to those of plasma levels (5,6).
To determine the maximum tolerated dose (MTD) of Busulfex ® in children with recurrent, progressive, or refractory primary brain tumors.
To obtain preliminary data regarding progression free survival (PFS) and event free survival (EFS) when Busulfex ® is used at submyeloablative doses in children with recurrent, progressive, or refractory primary brain tumors.
To describe the plasma pharmacokinetics of Busulfex ® in children with recurrent, progressive, or refractory primary brain tumors, using a continuous infusion.
