Brief Summary: 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
Detailed Description: Phenylbutyrate is an aromatic fatty acid that is converted to phenylacetate in vivo by mitochondrial beta-oxidation to phenylacetate Preclinical studies have shown that continuous exposure to phenylacetate or phenylbutyrate can induce tumor cytostasis and differentiation in a wide variety of cell lines including malignant gliomas and neuroblastomas However phenylbutyrate has been shown to be a more potent differentiating agent than phenylacetate in a variety of tumor cell lines In addition phenylbutyrate appears to have molecular activities that are distinct from phenylacetate The objective of this trial is to determine the maximum tolerated dose and the toxicities of phenylbutyrate administered as a continuous intravenous infusion for 28 days In addition the pharmacokinetics of phenylbutyrate and its metabolite phenylacetate will be studied using both model-dependent and model-independent parameters
