Brief Title
Azacitidine and Gemtuzumab Ozogamicin in Treating Older Patients With Previously Untreated Acute Myeloid Leukemia
Official Title
A Phase II Trial of Azacitidine (NSC-102816) Plus Gemtuzumab Ozogamicin (NSC-720568) as Induction and Post-Remission Therapy in Patients of Age 60 and Older With Previously Untreated Non-M3 Acute Myeloid Leukemia
Brief Summary
This phase II trial is studying the side effects of giving azacitidine together with
gemtuzumab ozogamicin to see how well it works in treating older patients with previously
untreated acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in
different ways to stop the growth of cancer cells, either by killing the cells or by stopping
them from dividing. Azacitidine may also stop the growth of cancer cells by blocking some of
the enzymes needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin, can
block cancer growth in different ways. Some block the ability of cancer cells to grow and
spread. Others find cancer cells and help kill them or carry cancer-killing substances to
them. Giving azacitidine together with gemtuzumab ozogamicin may kill more cancer cells.
Detailed Description
PRIMARY OBJECTIVES:
I. To test whether outcomes of patients of age 60 or older with previously untreated non-M3
acute myeloid leukemia treated with azacitidine plus gemtuzumab ozogamicin are sufficient to
warrant phase III investigation.
II. To estimate the frequency and severity of toxicities of this regimen in the good- and
poor-risk groups of patients.
III. To investigate in a preliminary manner the disease-free survival of patients who achieve
complete remission and receive post-remission therapy on this study.
IV. To investigate in a preliminary manner the cytogenetic response rates of patients treated
with this regimen.
V. To investigate in a preliminary manner the effects of cytogenetic abnormalities, promoter
and global methylation changes, and multidrug resistance on overall survival and response to
azacitidine plus gemtuzumab ozogamicin therapy.
OUTLINE: Patients are stratified according to risk status (good [60-69 years of age OR Zubrod
performance status [PS] 0-1] vs poor [>= 70 years of age AND Zubrod PS 2-3]).
REMISSION INDUCTION THERAPY: Patients receive azacitidine intravenously (IV) over 10-40
minutes or subcutaneously (SC) once daily (QD) on days 1-7 and gemtuzumab ozogamicin IV over
2 hours on day 8. Patients with residual leukemia (blast count >= 5%) receive a second course
of induction therapy beginning between days 15-29. Patients achieving complete remission (CR)
or morphologic complete remission with incomplete blood count recovery (CRi) go on to receive
consolidation therapy.
CONSOLIDATION THERAPY: Patients receive one course of azacitidine and gemtuzumab ozogamicin
as in induction therapy (with azacitidine given SC only).
MAINTENANCE THERAPY: Patients receive azacitidine SC on days 1-7. Treatment repeats every 28
days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients
undergo bone marrow biopsies for cytogenetic studies at baseline, remission, and relapse or
progression (and at completion of treatment if it does not correspond to one of these time
points). Marrow and blood samples are submitted to correlatives studies and submitted to
Southwest Oncology Group (SWOG) acute lymphoblastic leukemia (ALL)/chronic lymphocytic
leukemia (CLL)/chronic myelogenous leukemia (CML) Repository in Seattle, WA.
After completion of study therapy, patients are followed every 2 months for 2 years, every 3
months for 1 year, every 4 months for 1 year, and then every 6 months thereafter.

Eligibility Criteria
Inclusion Criteria:
- Morphologically confirmed diagnosis of acute myeloid leukemia (AML) with
classification other than WHO acute promyelocytic leukemia (FAB M3), based on bone
marrow examination performed within 14 days prior to registration; patients with World
Health Organization (WHO) acute promyelocytic leukemia (FAB M3) or blastic
transformation of chronic myelogenous leukemia are not eligible
- Zubrod performance status 0-3
- No known hypersensitivity to azacitidine, mannitol, hydroxyurea, orgemtuzumab
ozogamicin
- No prior systemic chemotherapy for acute leukemia with the exception of hydroxyurea;
administration of hydroxyurea to control high white blood cell (WBC) count prior to
registration is permitted
- Patients with a history of prior myelodysplastic syndrome (MDS) are eligible according
to the following criteria:
- No prior treatment of MDS with AML induction-type chemotherapy or high-dose
chemotherapy with hematopoietic stem cell support
- Prior cytarabine allowed if dose < 100 mg/m^2/day
- Prior hematopoietic growth factors, thalidomide, lenalidomide, arsenic trioxide,
and signal transduction inhibitors for treatment of MDS allowed
- No prior treatment with azacitidine, decitabine, or gemtuzumab ozogamicin
- At least 30 days since prior therapy for MDS and recovered
- Bilirubin =< 2.0 x institutional upper limit of normal (IULN) within 14 days to
registration, unless the elevation is believed to be due to hepatic infiltration by
AML

secondary to Gilbert syndrome or hemolysis is allowed
