Bortezomib in Treating Patients With High-Risk Acute Myeloid Leukemia in Remission

PRIMARY OBJECTIVES: I. To determine if bortezomib when given as maintenance therapy for six months post-remission can improve the progression-free survival (PFS) rate by 50% (or 4.5 months) in first remission patients with high-risk AML. SECONDARY OBJECTIVES: I. To determine the overall survival (OS) after maintenance therapy with bortezomib in first remission AML patients. II. To assess the safety and tolerability of subcutaneous (SC) administration of bortezomib given as maintenance therapy to first remission AML patients. OUTLINE: Patients receive bortezomib SC on days 1, 8, 15 and 22. Treatment repeats every 35 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 4 weeks, every 3 months for 2 years, and then annually for 3 years.
