Abstract

Purpose: Decitabine, a DNA-targeted hypomethylating agent, is approved by the United States Food and Drug Administration for treatment of patients with myelodysplastic syndromes (MDS) on a schedule of 15 mg/m2 administered via intravenous (IV) infusion every 8 hours for 3 days. This study assessed the efficacy and safety of an alternative dosing regimen administered on an outpatient basis in academic and community-based practices. Patients and Methods: Patients were treated with decitabine 20 mg/m2 by IV infusion daily for 5 consecutive days every 4 weeks. Eligible patients were ≥ 18 years of age and had MDS (de novo or secondary) of any French-American-British (FAB) subtype and an International Prognostic Scoring System (IPSS) score ≥ 0.5. The primary end point was the overall response rate (ORR) by International Working Group (IWG 2006) criteria; secondary end points included cytogenetic responses, hematologic improvement (HI), response duration, survival, and safety. Results: Ninety-nine patients were enrolled; the ORR was 32% (17 complete responses [CR] plus 15 marrow CRs [mCRs]), and the overall improvement rate was 51%, which included 18% HI. Similar response rates were observed in all FAB subtypes and IPSS risk categories. Among patients who improved, 82% demonstrated responses by the end of cycle 2. Among 33 patients assessable for a cytogenetic response, 17 (52%) experienced cytogenetic CR (n = 11) or partial response (n = 6). Conclusion: Decitabine given on a 5-day schedule provided meaningful clinical benefit for patients with MDS, with more than half demonstrating improvement. This suggests that decitabine can be administered in an outpatient setting with comparable efficacy and safety to the United States Food and Drug Administration-approved inpatient regimen.
