Experimental: Arm I
Patients will receive an infusion of bortezomib twice a week for 2 weeks. They will also receive tipifarnib by mouth twice a day for 2 weeks.

I. Determine the dose-limiting toxicity and maximum tolerated dose of tipifarnib and bortezomib in patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myeloid leukemia in blast phase.
I. Determine the effect of this regimen on farnesyltransferase and proteasome inhibition in peripheral blood mononuclear cells in these patients.
II. Determine the clinical efficacy of this regimen in these patients.
OUTLINE: This is a dose-escalation study.
Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11 and oral tipifarnib twice daily on days 1-14. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients with partial response or stable disease may continue therapy beyond 6 courses at the discretion of the investigator.
Cohorts of 3-6 patients receive escalating doses of bortezomib and tipifarnib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Blood is collected periodically for protein expression studies. Bone marrow aspirates obtained at baseline are examined by immunohistochemistry for Ki-67 activity.
