The purposee of this study is to determine the safety and dosing of Fenretinide when given continuously for 5 days, every 3 weeks, in pediatric patients with recurrent and/or resistant acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), and non-Hodgkin's lymphoma (NHL).
Fenretinide is a cytotoxic retinoid that has activity against a variety of cell lines in vitro in a dose-related manner. The exact mechanism of fenretinide cytotoxicity in leukemia and lymphoma cell lines is not known, but may include the de novo ceramide synthesis of ceramides and the generation of reactive oxygen species. The malignancy-specific nature of fenretinide-induced ceramides suggests that combinations of the drug with other ceramide modulating agents may have a favorable therapeutic index. In this study, the primary aims are to define the maximum tolerated dose, toxicity profile, and pharmacokinetics of IV fenretinide when given continuously in pediatric patients with ALL, AML, and NHL. The drug will be administered via a central venous or percutaneous indwelling central catheter in an inpatient hospital setting.

925 mg/m2 IV continuous infusion X 5 days for 6 cycles. Dose escalation will occur on a 3X3 basis.
dosing depending on age - will be administed intrathecally for all CNS negative subjects on day 0 and 15 of course 1, then on day 8 of each remaining cycle for CNS negative AML. For CNS positive ALL, NHL, and AML, will be administered alone on day 0 for and in combination with methotrexate and hydrocortisone on day 8, 15, 22 of cycle 1 and repeated on day 8 of each remaining cycle
Dose depends on subject age - for CNS positive patients, will be given in combination with cytarabine and hydrocortisone on days 8, 15, and 22 during course 1. For courses 2-6, will be administered intrathecally on day 8 for CNS negative ALL and NHL. For patients who are CNS positive, it will be given in combination with cytarabine and hydrocortisone on day 8 of courses 2-6.
