Phase II Trial of Vorinostat (Suberoylanilide Hydroxamic Acid or SAHA; Zolinza?) in Combination With Gemtuzumab Ozogamicin (Mylotarg?) as Induction and Post-Remission Therapy in Older Patients With Previously Untreated Non-M3 Acute Myeloid Leukemia
RATIONALE: Vorinostat may stop the growth of cancer cells by interfering with various proteins needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin (GO), can block cancer growth in different ways. GO finds cancer cells and helps kill them by carrying a cancer-killing substance to them. Giving vorinostat together with gemtuzumab ozogamicin may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving vorinostat together with gemtuzumab ozogamicin works in treating older patients with previously untreated acute myeloid leukemia.
Stanford is not currently accepting new patients for this trial. You may want to check clinicaltrials.gov to see if other locations are recruiting.

Phase: Phase 2
Ages Eligible For Study:
- Morphological diagnosis of AML other then acute promyelocytic leukemia (FAB M3) according to WHO diagnostic criteria; diagnosis of AML must be based on bone marrow or peripheral blood studies obtained within 28 days prior to study registration or start of hydroxyurea (for patients presenting with WBC >= 10,000/uL), and no potentially anti-leukemic therapy (with the exception of hydroxyurea) must have been given between AML diagnosis and study registration; a bone marrow biopsy is not routinely required but should be obtained if the aspirate is dilute, hypocellular, or inaspirable; outside bone marrows performed within the stipulated time period are acceptable as long as the slides are reviewed at a study institution - Cytogenetic analysis on bone marrow or peripheral blood specimen is available; based on the result from the first interim analysis, patients stratified into the good-risk group are only eligible if their AML has favorable cytogenetics (core-binding factor AML) or has a normal karyotype; patients stratified into the poor-risk group are eligible independent of the cytogenetic analysis - Pretreatment bone marrow and peripheral blood specimens for correlative studies are available; if bone marrow was performed at an outside facility, submission of peripheral blood only is acceptable as long as the peripheral blast count is > 5,000/uL and > 50% of total WBC - Patients with a history of antecedent MDS are eligible, if prior treatment did not include intensive chemotherapy; patients may have received hematopoietic growth factors, thalidomide/lenalidomide, 5-azacytidine/decitabine, arsenic trioxide, signal transduction inhibitors, or low dose cytarabine (< 100 mg/m2/day) for treatment of MDS; patients must be off prior therapy for MDS at least 30 days prior to study registration, and all non-hematologic toxicities must have resolved to < grade 2 - ECOG/WHO/Zubrod performance status of 0-3 - Bilirubin =< 2.5 x Institutional Upper Limit of Normal (IULN) unless elevation is thought to be due to hepatic infiltration by AML, Gilbert's syndrome, or hemolysis (assessed within 14 days prior to registration) - SGOT (AST) and SPGT (ALT) =< 1.5 x IULN unless elevation is thought to be due to hepatic infiltration by AML (assessed within 14 days prior to registration) - Serum creatinine =< 1.5 x IULN (assessed within 14 days prior to registration) - Left ventricular ejection fraction >= 40% and no clinical evidence of congestive heart failure (assessed within 28 days prior to registration, e.g. by MUGA scan or echocardiography) - Men of reproductive potential must use an effective contraceptive method throughout the study and for a period of at least 3 months after the study - Women must be postmenopausal; a postmenopausal woman is defined as a woman who has experienced amenorrhea > 12 consecutive months or a woman on hormone replacement therapy with documented FSH level > 35 mIU/mL (women of childbearing potential must have a pregnancy test within 28 days prior to registration, and must use an adequate method of contraception to avoid pregnancy throughout the study and for a period of at least 3 months after the study) - Provide signed written informed consent - Willingness to undergo bone marrow examination on day 8 of first induction cycle - WBC < 10,000/uL (patients with WBC >= 10,000/uL must undergo cytoreduction with hydroxyurea prior to enrollment and will not be enrolled if the WBC remains >= 10,000/uL (of note, patients with symptoms/signs of hyperleukocytosis or WBC > 100,000/uL can be treated with leukapheresis prior to enrollment)
