Clinical Trial: Idarubicin and Cytarabine With or Without Bevacizumab in Treating Patients With Newly Diagnosed Acute Myeloid Leukemia

Study Status: Terminated
Recruit Status: Terminated
Study Type: Interventional

Official Title: Randomized Phase II Trial of Idarubicin + Ara-C +/- Bevacizumab in Patients Age < 60 With Untreated Acute Myeloid Leukemia

Brief Summary: 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. Bevacizumab may stop the growth of cancer by stopping blood flow to the leukemic cells in the bone marrow. Giving idarubicin and cytarabine with bevacizumab may kill more cancer cells. It is not yet know whether giving idarubicin together with cytarabine is more effective with or without bevacizumab in treating acute myeloid leukemia. This randomized phase II trial is studying how well giving idarubicin and cytarabine together with bevacizumab works compared to idarubicin and cytarabine alone in treating patients with newly diagnosed acute myeloid leukemia

Detailed Summary:

PRIMARY OBJECTIVES:

I. Compare the activity of idarubicin and cytarabine with or without bevacizumab in patients with newly diagnosed acute myeloid leukemia.

II. Compare the proportion of patients who survive and remain in first complete remission (CR) one year from achieving CR after treatment with these regimens.

SECONDARY OBJECTIVES:

I. Compare the safety of these regimens in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age (< 45 vs 45 to 59), cytogenetics (normal vs -5/-7 vs other), flt 3 status (normal vs mutated), and type of acute myeloid leukemia (AML) (de novo vs secondary [arising after cytotoxic therapy or after an antecedent hematologic disorder, defined as a documented abnormality in blood count for >= 3 months before diagnosis of AML]. Patients who require treatment before cytogenetics or flt 3 status is known (e.g., patients with WBC > 50,000 OR with organ dysfunction thought to be due to blast infiltration) are stratified only according to age and type of AML. Induction therapy: Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive idarubicin IV over 1 hour on days 1-3 and cytarabine IV continuously over 24 hours on days 1-4.

Arm II: Patients receive idarubicin and cytarabine as in arm I. Patients also receive bevacizumab* IV over 30-90 minutes on day 1. Patients who do not achieve complete remission (CR) after the first induction course may receive a second induction course approximately 28 days* later. Patients who do not achieve CR after 2 courses are removed from the study
Sponsor: National Cancer Institute (NCI)

Current Primary Outcome: Proportion of patients who remain alive in the first complete remission (CR) 1 year from achievement of CR assessed every 3 weeks for 1 year [ Time Frame: 13 months from registration ]

Fisher's exact test will be used to compare the proportion of patients alive in CR 13 months from registration date. The test has approximately 89% power to detect an absolute increase of 20% in this proportion, testing at the one-sided 0.15 significance level.


Original Primary Outcome:

Current Secondary Outcome: Safety of idarubicin+cytarabine+bevacizumab by AdEERS, CBC and chem. [ Time Frame: Up to 2 years after study completion ]
