About

RATIONALE: 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.

PURPOSE: This phase II trial is studying how well azacitidine works in treating patients with acute myeloid leukemia who are unsuitable for treatment with intensive chemotherapy.

Full description

OBJECTIVES:

Primary

• To evaluate the efficacy of azacitidine in patients with newly diagnosed or untreated acute myeloid leukemia who are unsuitable for induction type chemotherapy because of age or relevant comorbidities.

Secondary

• To evaluate survival and adverse events.

OUTLINE: This is a multicenter study.

Patients receive azacitidine subcutaneously on days 1-5. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months for 1 year.

Enrollment: 47 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
