A Survival Study in Patients With High Risk Myelodysplastic Syndromes Comparing Azacitidine Versus Conventional Care

An NCI or FDA source cites this study. A citation does not establish that it applies to an individual diagnosis.

Phase: PHASE3
Status at capture: COMPLETED
Registry last update: 2019-10-29

The purpose of this study is to determine whether patients with high-risk myelodysplastic syndromes (MDS) treated with azacitidine have improved survival compared to conventional care treatments. The study will also assess the effect of treatments on response, duration of response, and transformation to acute myeloid leukemia (AML). The study will continue for 12 months following last patient enrolled. See study AZA PH GL 2003 CL 001 E for information about the extension to this study.

Azacitidine
description
Azacitidine was injected subcutaneously (SC) at an initial dose of 75mg/m\^2/day for 7 days. The 7-day dosing was repeated every 28 days with dose adjustment based on predefined hematology and renal laboratory results. Number of cycles: Azacitidine treatment was to be continued until the end of the study unless treatment was discontinued due to unacceptable toxicity, relapse after complete or partial response, transformation to AML or disease progression.

Physician Choice was one of three options: * Best supportive care (BSC) alone, * Low-dose cytarabine subcutaneously for 14 days every 28 to 42 days, or * Standard chemotherapy administered for induction as a continuous intravenous infusion of cytarabine over 7 days plus an anthracycline (daunorubicin, idarubicin, or mitoxantrone) on Days 1, 2, and 3; and, for those eligible, 1 or 2 consolidation cycles administered as continuous intravenous infusions of cytarabine for 3 to 7 days with the same anthracycline that was used at induction on Days 1 and 2 (each cycle between 28 to 70 days from the start of the previous cycle).

Full study description

brief Summary: The purpose of this study is to determine whether patients with high-risk myelodysplastic syndromes (MDS) treated with azacitidine have improved survival compared to conventional care treatments. The study will also assess the effect of treatments on response, duration of response, and transformation to acute myeloid leukemia (AML). The study will continue for 12 months following last patient enrolled. See study AZA PH GL 2003 CL 001 E for information about the extension to this study.
detailed Description: Comparison/Control Interventions offered the physician three options: * Best supportive care (BSC) alone, * Low-dose cytarabine subcutaneously for 14 days every 28 to 42 days, or * Standard chemotherapy administered for induction as a continuous intravenous infusion of cytarabine over 7 days plus an anthracycline (daunorubicin, idarubicin, or mitoxantrone) on Days 1, 2, and 3; and, for those eligible, 1 or 2 consolidation cycles administered as continuous intravenous infusions of cytarabine for 3 to 7 days with the same anthracycline that was used at induction on Days 1 and 2 (each cycle between 28 to 70 days from the start of the previous cycle). All three options included best supportive care. Neither the experimental group (azacitidine) nor any of the comparison/control options allowed use of erythropoietin. Duration of Intervention: Patients will be treated until death, withdrawal, unacceptable toxicity or conclusion of the study.
