Brief Summary

This phase II trial is studying how well cediranib maleate works in treating patients with relapsed, refractory, or untreated acute myeloid leukemia or high-risk myelodysplastic syndrome. Cediranib maleate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. Evaluate the objective response rate in patients with relapsed, refractory, or untreated acute myeloid leukemia or high-risk myelodysplastic syndromes treated with AZD2171 (cediranib maleate).

SECONDARY OBJECTIVES:

I. Determine the toxicity of this drug in these patients. II. Determine the response duration, event-free survival, and overall survival of patients treated with this drug.

III. Determine the hematological response rate in patients treated with this drug.

OUTLINE: This is a multicenter study. Patients are stratified according to disease (acute myeloid leukemia vs myelodysplastic syndromes).

Patients receive oral cediranib maleate once daily (QD) on days 1-28. Treatment repeats every 28 days for up to 26 courses in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow biopsy at baseline and on day 28 for correlative studies. Samples are analyzed for circulating endothelial cells, VEGF receptor expression, and leukemic blasts via flow cytometry and microvessel density via histopathological techniques.

After completion of study treatment, patients are followed up at 3 months and then every 6 months for up to 2 years.

Arm && Interventions

Treatment (enzyme inhibitor therapy)	laboratory biomarker analysis	Patients receive oral cediranib maleate QD on days 1-28. Treatment repeats every 28 days for up to 26 courses in the absence of disease progression or unacceptable toxicity.
Treatment (enzyme inhibitor therapy)	cediranib maleate	Patients receive oral cediranib maleate QD on days 1-28. Treatment repeats every 28 days for up to 26 courses in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
The Number of Confirmed Disease Response: Complete Response (CR), Partial Response (PR), and Hematologic Improvement (HI). A Confirmed Response is Defined to be an Objective Status of CR, PR, or HI Noted on 2 Consecutive Evaluations.	At the end of cycles 1 and 3 and every 3 cycles thereafter up to 26 cycles	Complete Response (CR) requires a repeat bone marrow with \< 5% myeloblasts, hemoglobin ≥ 11 g/dl, neutrophils ≥ 1000/mm3, platelets ≥ 100,000/mm3, and no circulating blasts.; Partial Response (PR) requires a bone marrow blast reduction of 50% or more, hemoglobin ≥ 11 g/dl, neutrophils ≥ 1000/mm3, platelets ≥ 100,000/mm3, and no circulating blasts.; Hematologic Improvement (HI) requires one of the following: 1. RBC transfusion independent participants are required to have \>1.5 g/dL increase in hemoglobin,; 2. RBC transfusion-dependent participants are required to be transfusion independent,; 3. A 100% increase, and an absolute increase over 500mm\^3 in Absolute Neutrophil Count,; 4. Participants with a pretreatment platelet count over 20,000/mm3 require an absolute increase of 30,000/mm\^3 or more,; 5. Participants with platelet count below 20,000/mm3 require an increase over 20,000/mm\^3 and by at least 100%.

Secondary Outcome Measures

Name	Time	Method
Overall Survival	Every cycle during treatment and every 6 months for up to 2 years after completion of study treatment	Defined as the time from date of registration to date of death due to any cause or date last known alive. The distribution of survival time will be estimated using the method of Kaplan-Meier.
Progression-free Survival	Every 3 courses during treatment and then at 3 months and every 6 months for up to 2 years after completion of study treatment	Defined as the time from date of registration to date that disease progression was documented, death, or last date that progression-free status was documented, whichever comes first. Estimated using the method of Kaplan-Meier.; Disease progression is defined as one of the following: * A ≥ 50% increase in bone marrow blasts from the best response, or; * A 50% or greater decrement from maximum remission/response levels in neutrophils or platelets, or; * A reduction in hemoglobin concentration by at least 1.5 g/dl, or; * Transfusion dependence (without alternative explanation and sustained for at least 2 weeks).
Duration of Response	Every 3 courses up to 26 courses	Measured from the time criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented. Estimated using the method of Kaplan-Meier.
The Number of Patients That Report Adverse Events Possibly, Probably, or Definitely Related to AZD2171.	Continuously during treatment up to 26 courses	Graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. All adverse events determined to be possibly, probably, or definately related to AZD2171 are included in this analysis.
