Brief Title: Tipifarnib in Treating Older Patients With Previously Untreated Acute Myeloid Leukemia
Official Title: A Phase II Study of Farnesyl Transferase Inhibitor R115777 (Zarnestra) (R115777 ( Zarnestra), Tipifarnib, R115777, NSC #702818) in Elderly Patients With Previously Untreated Poor-Risk Acute Myeloid Leukemia
Study ID: NCT00027872
Brief Summary: Tipifarnib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Phase II trial to study the effectiveness of tipifarnib in treating older patients who have previously untreated acute myeloid leukemia
Detailed Description: PRIMARY OBJECTIVES: I. To determine the complete response rate of R115777 (tipifarnib) in previously untreated acute myeloid leukemia (AML) in (a) elderly patients (age \>= 75) and (b) patients (age \>= 65) with AML preceded by myelodysplastic syndrome (MDS), using a chronic dosing schedule. SECONDARY OBJECTIVES: I. To determine progression-free and overall survival in patients with previously untreated AML treated with R115777, using a chronic dosing schedule. II. To determine the duration of response in patients with previously untreated AML treated with R115777, using a chronic dosing schedule. III. To determine the effect of R115777 on the phosphorylation of mitogen-activated protein kinase (MAPK) and phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PI3K) in leukemic cells. IV. To determine the effect of R115777 on processing of the farnesylated protein HDJ-2. V. To determine the toxicities of R115777 when given in a chronic dosing schedule. OUTLINE: This is a multicenter study. Patients receive oral tipifarnib twice daily on days 1-21. Patients with a complete or partial response, hematologic improvement, or stable disease continue treatment every 29-63 days in the absence of disease progression or unacceptable toxicity. Patients with a complete response after the second course of therapy receive 2 additional courses of therapy. Patients are followed for survival. PROJECTED ACCRUAL: A total of 125 patients will be accrued for this study within 11-17 months.
