Study Description

Brief Summary

This clinical trial studies the side effects of gemtuzumab ozogamicin and how well it works in treating patients with acute myeloid leukemia. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them

Detailed Description

PRIMARY OBJECTIVES:

To study safety and efficacy single agent Gemtuzumab Ozogamicin (Mylotarg®) as induction therapy for patients with Acute Myeloid Leukemia (AML) who have relapsed after standard treatments or who are not candidates for standard consolidation treatment after Daunorubicin and cytosine arabinoside.

SECONDARY OBJECTIVES:

To correlate morbidity and mortality with the use of gemtuzumab (gemtuzumab ozogamicin) to specific subtypes of leukemia.
To correlate gemtuzumab response to degree of cluster of differentiation (CD) 33 positivity.
To correlate FMS-Related Tyrosine Kinase 3 (FLT 3)/nucleophosmin (NPM) status and CD 33 positivity to gemtuzumab response.
To document incidence of sinusoidal obstruction syndrome with the use of gemtuzumab.

OUTLINE:

Patients receive gemtuzumab ozogamicin intravenously (IV) over 2 hours on days 1 and 15. Treatment continues for 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up monthly for 1 year.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Patients must have confirmed relapsed or refractory acute myeloid leukemia and not a candidate for standard induction treatment after daunorubicin and cytosine arabinoside OR acute promyelocytic leukemia relapsed after all-trans retinoic acid (ATRA) or Arsenic trioxide therapy
Patients must have an initial diagnosis of acute myeloid leukemia or biphenotypic acute leukemia
Patients must have CD33 positivity of >= 30%
Eastern Cooperative Oncology Group (ECOG) performance status =< 3
Karnofsky > 60%
Total bilirubin within normal institutional limits
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase [SGPT]) =< 2 X institutional upper limit of normal
Creatinine within normal institutional limits OR creatinine clearance >= 30 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
The effects of Mylotarg on the developing human fetus are unknown; for this reason and because Mylotarg class agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

Patients may not be receiving any other investigational agents for leukemia
Patients with known untreated Hepatitis C because veno-occlusive disease and liver enzyme abnormalities have been associated with Mylotarg
Uncontrolled intercurrent illness including, but not limited to active liver disease, ongoing or active sepsis requiring vasopressors or mechanical ventilation, symptomatic congestive heart failure, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant women are excluded from this study because Mylotarg is a Class D agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with Mylotarg, breastfeeding should be discontinued if the mother is treated with Mylotarg
Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with Mylotarg; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
Congestive Heart Failure (CHF) with an ejection fraction < 30%
Glomerular filtration rate (GFR) < 30ml/min
Active central nervous system (CNS) involvement of leukemia
Philadelphia chromosome + acute lymphoblastic leukemia (ALL)
Prior hematopoietic transplant in last 3 months
