Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 135
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the effectiveness and safety of decitabine in the treatment of myelodysplastic syndrome (name of a group of conditions that occur when the blood-forming cells in the bone marrow are damaged) in Chinese patients.

Detailed description:
This is a prospective (look forward using periodic observations collected predominantly following patient enrollment), open-label (all people involved in the study know the identity of the assigned drug), Phase IIIb study to evaluate the efficacy and safety of decitabine in the treatment of myelodysplastic syndrome (MDS). Patients are randomized (study drug assigned by chance) in 1:1 ratio to receive treatment with decitabine either 3-day or 5-day course of therapy. When a minimum of 30 patients are reached for 3-day course of therapy, the rest of the patients will all be enrolled into 5-day course of therapy. Each patient in the study treated for a minimum of 4 cycles; however, a complete or partial response may take longer than 4 cycles. The entire study duration for each patient will be approximately two years. Safety will be evaluated for each patient by monitoring of adverse events, physical examinations, vital signs measurements, electrocardiogram, hematology and clinical chemistry testing.

Arms:
arm 1: Decitabine will be administered at a dose of 15 mg/m2 as a continuous intravenous infusion within a 3 hour period, repeated every 8 hours for 3 consecutive days. Cycles will be repeated every 6 weeks. arm 2: Decitabine will be administered at a dose of 20 mg/m2 as a intravenous infusion within 1 hour, once daily for 5 consecutive days. Cycles will be repeated every 4 weeks.

Interventions: intervention 1: Decitabine at 15 mg/m2 intervention 2: Decitabine at 20 mg/m2
Intervention descriptions: intervention 1: Decitabine will be given at a dose of 15 mg/m2 as a continuous intravenous infusion within a 3-hour intravenous infusion, repeated every 8 hours for 3 consecutive days.The total dose per day is 45 mg/m2; The total dose per course is 135 mg/m2. Cycles will be repeated every 6 weeks. intervention 2: Decitabine will be given at a dose of 20 mg/m2 as 1-hour IV infusion once daily on Days 1 through 5, of a 4-week treatment cycle.
