Patients with myelodysplastic syndromes treated with azacitidine in clinical practice: the AVIDA^® registry

Abstract

The AVIDA registry evaluated azacitidine usage and effectiveness in unselected patients with myelodysplastic syndromes (MDS) in community practice. Treating physicians made all treatment decisions. Hematologic improvement (HI) and transfusion independence (TI) assessments used International Working Group (IWG) 2000 criteria. Enrolled were 421 patients with MDS (n = 228 International Prognostic Scoring System [IPSS] lower-risk, n = 106 higher-risk, 86 patients unclassified) from 105 US sites. Median follow-up was 7.6 months (range: 0.1–27.6). HI and red blood cell TI rates were similar regardless of administration route or dosing schedule. Safety and tolerability were consistent with previous reports. The AVIDA registry data support azacitidine effectiveness and safety in patients with lower- or higher-risk MDS treated in community practice.
