Multicenter Study of Decitabine Administered Daily for 5 Days Every 4 Weeks to Adults With Myelodysplastic Syndromes: The Alternative Dosing for Outpatient Treatment (ADOPT) Trial
Bibliographic record
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/m(2) 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/m(2) by IV infusion daily for 5 consecutive days every 4 weeks. Eligible patients were > or = 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 > or = 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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
