A Phase II Study of AZD2171 in the Treatment of Patients With Acute Leukemia and Myelodysplastic Syndrome

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


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).


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

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