Tipifarnib, Cytarabine, and Daunorubicin in Treating Older Patients With Acute Myeloid Leukemia

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine and daunorubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving tipifarnib together with cytarabine and daunorubicin may kill more cancer cells.

PURPOSE: This phase I trial is studying the side effects and best dose of tipifarnib when given with cytarabine and daunorubicin in treating older patients with acute myeloid leukemia.
