An Effectiveness and Safety Study of Decitabine in Patients With Myelodysplastic Syndrome
- Conditions
- Myelodysplastic Syndrome
- Interventions
- Registration Number
- NCT01751867
- Lead Sponsor
- Xian-Janssen Pharmaceutical Ltd.
- 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.

Group Intervention Description 3-Day Dose schedule Decitabine at 15 mg/m2 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. 5-Day Dose schedule Decitabine at 20 mg/m2 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.
- Primary Outcome Measures
Name Time Method Overall Response Rate (ORR): Number of Participants Who Achieved Either Complete Remission (CR), Partial Remission (PR), or Marrow Complete Remission (mCR) - International Working Group (IWG) 2006 Response Criteria From the date of first dose until 30 to 42 days after the last dose of the 2 years treatment period, or at time of discontinuation IWG 2006 response criteria - CR: bone marrow evaluation shows less than or equal to (\<=) 5% blasts; normal maturation of all cells lines (mCR), peripheral blood evaluation shows hemoglobin \>= 11 gram per deciliter (g/dL), neutrophils \>= 1000/mL, platelets \>= 100,000/mL, 0% blasts; PR: Same as CR, except blasts decrease by \>=50%, still greater than 5% in bone marrow.
- Secondary Outcome Measures
Name Time Method Mean Percentage of Duration of Hospitalization (Relative to Days on Study Treatment) Up to 2 years Duration of hospitalization was calculated as, total number of days a participant stayed in hospital during study treatment divided by the study treatment duration
Overall Survival Rate: Percentage of Participants Who Survived During 6 Months and 12 Months of Treatment. From the date of dosing until death or lost to follow-up for up to 2.5 years after last patient was enrolled Mean Change From Baseline to End of Treatment in Scores of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ C-30) Physical Functioning Scale Baseline to end of treatment (approximately up to 2 years) EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients. It is composed of 30 items, multi-item measure (28 items) and 2 single-item measures. For the multiple item measure, 4-point scale is used and the score for each item range from "1 = not at all" to "4 = very much". Higher scores indicate worsening. The 2 single-item measure involves question about the overall health and overall quality of life which will be rated on a 7-point scale ranging from "1 = very poor" to "7 = excellent". Lower scores indicate worsening. Scores are averaged, and transformed to 0-100 scale; higher score=better level of physical functioning.
Hematological Improvement Rate: Number of Participants Who Achieved Complete Remission (CR), Partial Remission (PR) and Hematologic Improvement (HI) - International Working Group (IWG) 2006 Response Criteria From the date of first dose until 30 to 42 days after the last dose of the 2 years treatment period, or at time of discontinuation IWG 2006 response criteria - CR: bone marrow evaluation shows \<= 5% blasts; normal maturation of all cells lines (mCR), peripheral blood evaluation shows hemoglobin \>= 11 g/dL, neutrophils \>= 1000/mL, platelets \>= 100,000/mL, 0% blasts; PR: Same as CR, except blasts decrease by \>= 50%, still greater than 5% in bone marrow; HI: hemoglobin increase of \>= 1.5 g/dL, platelet increase of \>= 30,000/mL (starting with \> 20,000/mL), neutrophils increase of \>= 100% and \> 500/μL.
Transfusion Independence: Number of Participants Who Were Transfusion Independent Baseline; up to 2 years A participant was considered to be transfusion independent, if the participant had no transfusions of Red Blood Cells (RBCs) or platelets for 8 consecutive weeks or more.
Cytogenetic Response Rate: Percentage of Participants Who Achieved Cytogenetic Response (Complete+Partial) by Status of Clinical Overall Response - International Working Group (IWG) 2006 Response Criteria From the date of first dose until 30 to 42 days after the last dose of the 2 years treatment period, or at time of discontinuation As per IWG 2006 response criteria - Complete cytogenetic response: disappearance of the chromosomal abnormality without appearance of new ones; Partial cytogenetic response: At least 50% reduction of the chromosomal abnormality. Status of Clinical response - complete remission (CR); marrow CR (mCR); partial remission (PR).
