Phase I and Pharmacokinetic Trial of Phenylbutyrate Given as a Continuous Infusion in Pediatric Patients With Refractory Malignancy
This is a pharmacokinetic trial. Patients receive phenylbutyrate through a central venous catheter for each 28 day cycle. The first several days of drug administration should be inpatient. Cycles may be repeated if there is no tumor progression or dose limiting toxicities (DLT). There are no breaks between cycles.
Once a minimum of 3 patients have completed at least 4 weeks of therapy without DLT, new patients will be entered at the next dose level.

説明
Disease Characteristics:
Histologically proven cancer that is refractory to standard therapy.
Patients with neurofibromatosis having progressive inoperable plexiform neurofibromas with potential to cause significant morbidity are eligible.
Patients with brainstem gliomas histology may have histology requirements waived.
Patients without prior therapy are eligible if they have diseases with no available standard therapy.
Patients with evidence of bone marrow involvement by tumor, or a history of either bone marrow transplantation or extensive radiotherapy will be eligible, but inevaluable for hematologic toxicities.
Patients with greater than grade 2 neurocortical toxicity will be excluded.
PRIOR/CONCURRENT THERAPY:
