Idarubicin, Cytarabine, and Tipifarnib in Treating Patients With Newly Diagnosed Myelodysplastic Syndromes or Acute Myeloid Leukemia

May 9, 2014 updated by: National Cancer Institute (NCI)

PHASE I-II STUDY OF IDARUBICIN, CYTARABINE AND R115777 (TIPIFARNIB, ZARNESTRA; 702818; IND 58359), A FARNESYLTRANSFERASE INHIBITOR, IN PATIENTS WITH HIGH-RISK MYELODYSPLASTIC SYNDROMES AND ACUTE MYELOID LEUKEMIAS

This phase I/II trial is studying the side effects and best dose of tipifarnib when given with idarubicin and cytarabine and to see how well it works in treating patients with newly diagnosed myelodysplastic syndromes or acute myeloid leukemia. Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Tipifarnib (Zarnestra) may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Giving idarubicin and cytarabine with tipifarnib may kill more cancer cells.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the tolerability of the combination of R115777 (Zarnestra™) and Idarubicin plus cytarabine by defining the DLT and MTD. (Phase I) II. To determine the efficacy of the combination of Idarubicin, cytarabine and ZARNESTRA in patients with high-risk MDS and AML. (Phase II)

OUTLINE: This is a dose-escalation study of tipifarnib. Patients are stratified according to age (< 50 versus ≥ 50) and, in patients ≥ 50 years of age, cytogenetics (diploid versus unfavorable).

INDUCTION THERAPY:

PHASE I: Patients receive cytarabine IV continuously on days 1-3 (or 1-4), idarubicin intravenous (IV) over 1 hour on days 1-3, and oral tipifarnib twice daily on days 1-21. Treatment repeats every 21 days for up to 2 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 6 patients receive escalating doses of tipifarnib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

PHASE II: Patients receive cytarabine, idarubicin, and tipifarnib as in phase I at the MTD.

Patients in both phases who respond to induction therapy proceed to consolidation maintenance therapy.

CONSOLIDATION MAINTENANCE THERAPY: Patients receive consolidation therapy comprising cytarabine IV continuously on days 1-3, idarubicin IV over 1 hour on days 1-2, and tipifarnib twice daily on days 1-14. Treatment repeats every 4-6 weeks for 5 courses in the absence of unacceptable toxicity.

Patients then begin maintenance therapy comprising oral tipifarnib twice daily on day 1-21. Treatment repeats every 4-6 weeks for 6 courses in the absence of unacceptable toxicity.

  • Patients must be chemo-naïve, i.e. not have received any prior chemotherapy (except hydrea) for AML or MDS; they could have received transfusions, hematopoietic growth factors or vitamins; temporary measures such as pheresis or hydrea (0.5 to 5g daily for up to 3 days) are allowed
  • ECOG PS of 0-1 at screening
  • Creatinine =< 2 mg/dl
  • Total bilirubin =< 2 mg/dL, unless increase is due to hemolysis

Exclusion Criteria:

  • Subjects with APL
  • Presence of active systemic infection
  • Any coexisting medical condition that in the judgment of the treating physician is likely to interfere with study procedures or results
  • Nursing women, women of childbearing potential with positive urine pregnancy test, or women of childbearing potential who are not willing to maintain adequate contraception (such as birth control pills, IUD, diaphragm, abstinence, or condoms by their partner) over the entire course of the study
  • Known allergy to imidazole drugs (such as clotrimazole, ketoconazole, miconazole, econazole, fenticonazole, isoconazole, sulconazole, tioconazole, terconazole)

Time Frame: 21 Day Cycle
Complete Response (CR) is required bone marrow blasts ≤5% and recovery of normal hematopoiesis with an absolute neutrophil count (ANC) of 1*10^9/L or more and platelet count of 100*10^9/L or more; and a complete response without platelets (CRp) is the same criteria as CR but with platelet counts from 20*10^9/L to less than 100*10^9/L.
