Determine the maximum tolerated dose of PSC-833 in combination with mitoxantrone and etoposide in children with refractory or relapsed acute leukemia.\n\nII. Determine the effects of PSC-833 on mitoxantrone and etoposide pharmacokinetics.\n\nIII. Quantify MDR1 gene expression and MDR1 P-glycoprotein expression and function in patient-derived leukemia cells.\n\nOUTLINE: This is a dose escalation study of PSC-833.\n\nPatients undergo induction therapy consisting of etoposide IV and mitoxantrone IV on days 1-5. Patients then receive PSC-833 IV over 124 hours beginning on day 2. A second course is administered no sooner than 21 days from the start of the first course if the marrow is hypocellular after the first course. Patients with persistent disease after 2 induction courses are removed from the study. Patients receive a total of 3 courses of etoposide/mitoxantrone.

Patients who achieve complete remission after 2 induction courses receive 1 course of etoposide/mitoxantrone with PSC-833 as consolidation.
