Clinical Trial Summary

The purpose of this study is to evaluate the response rate of decitabine in previously treated and untreated Taiwanese participants with Myelodysplastic Syndrome (MDS - a disease associated with decreased production of blood cells, blood cells are produced but do not mature normally).

Description:

This is an open-label (a medical research study in which participants and researchers are told which treatments the participants are receiving, "unblinded"), multi-center (when more than 1 hospital or medical school team work on a medical research study), single-arm study of decitabine. The study will consist of 5 phases: Pre-treatment phase (before 30 days of first dose), Treatment phase (consist of 8 cycles, each cycle of 28 days), End-of-treatment phase (consist of 30-42 days after the last dose of cycle 8, or at time of discontinuation), Extension phase (1 cycle of 4 weeks) and Post-study phase or follow-up phase (every 2 months until 1 year, lost to follow-up or death). Participants who achieve a complete remission (when a medical problem gets better or goes away at least for a while) will be treated for at least 2 more cycles after first documentation of complete response (CR), after which treatment can be discontinued. Decitabine in a dose of 20 milligram per square meter (mg per m^2) will be administered intravenously over 1 hour infusion, 1 hour, once daily for 5 consecutive days of a 28 days cycle up to 8 cycles or continued until disease progression or unacceptable toxicity. The primary objective is to evaluate the best response rate (complete response and partial response). Participants' safety will be monitored throughout the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Response	Percentage of participants with response: complete response (CR) or partial response (PR) according to International Working Group (IWG) 2006 criteria was evaluated. CR in bone marrow is defined as<=to 5% myeloblasts with normal maturation of all cell lines and persistent dysplasia was noted in peripheral blood hemoglobin >=11 gram (g) per deciliter (dl), platelets >=100*10^9 liter (l), neutrophils >=1.0*10^9 l, Blasts 0%. Partial response is defined as all CR criteria if abnormal before treatment except: bone marrow blasts decreased by >=50% over pre-treatment but still >=5%.	Day 1 of Cycle 2, 4, 6, 8; each Cycle of 28 days and End of treatment (30-42 days after Cycle 8 or early withdrawal)	No
Secondary	Percentage of Participants With Hematologic Treatment Response	Hematologic treatment response was assessed as per IWG 2006 criteria. This is measured in erythroid(HI-E), platelet(HI-P) and neutrophil(HI-N) lineages. HI-E response(pre-treatment<11 gram per deciliter [g/dl]):hemoglobin increase by>=1.5 g/dl and relevant reduction in RBC transfusions by 4 RBC transfusions/8week. HI-P response (pre-treatment<100*109/l):absolute increase of >=30*10^9/l for participants starting with>20*10^9/l and increase from <20*10^9/l to>20*10^9/l and by at least 100%. HI-N response (pre-treatment<1.0*10^9/l): at least 100% increase and an absolute increase >0.5*10^9/l.	Day 1 of Cycle 1, 2, 3, 4, 5, 6, 7 and 8, each Cycle of 28 days and End of treatment (30-42 days after Cycle 8 or early withdrawal)	No
Secondary	Percentage of Participants With Cytogenetic Response	Cytogenetic responses was assessed as per IWG 2006 criteria which define complete response as disappearance of the chromosomal abnormality without appearance of new ones and partial response as at least 50 percent reduction of the chromosomal abnormality.	Day 1 of Cycle 2, 4, 6, 8; each Cycle of 28 days and End of treatment (30-42 days after Cycle 8 or early withdrawal)	No
Secondary	Time to Acute Myeloid Leukemia (AML) Progression or Death	Time to AML is defined as greater than 30 percent of blasts in bone marrow or the time to death was calculated from the date of treatment start until disease progression to AML or until death, which ever occurred first. Participants who were still alive and did not progress to AML were censored at the moment of last visit.	Start of treatment until disease progression or death (whichever occur first) or up to 736 days	No
Secondary	Overall Survival	Overall survival was defined as the time from the date of treatment start until death (whatever the cause). It was calculated from Kaplan-Meier estimates. Participants still alive were censored at the moment of last visit or contact.	Start of treatment until disease progression or death (whichever occur first) or up to 736 days	No
Secondary	Percentage of Participants With Transfusion Dependency	Transfusion requirements for both red blood cells as well as platelets were recorded for each participant.	8 weeks before first dose until disease progression or death (whichever occur first) or up to 736 days	No
Secondary	Percentage of Participants With Transfusion Independency	Transfusion independent participants were calculated from all the participants who required transfusion in the duration of 8 weeks before first dose until disease progression or death or up to 736 days. Transfusion independence was defined as lack of requirement for transfusions for at least 8 weeks.	8 weeks before first dose and 736 days of treatment	No
Secondary	Duration for Hospitalization	Duration of hospitalization was calculated for each participant, using the sum of all hospital days by subtracting the date of discharge from the date of admission.	Cycle 1 up to Cycle 8, each cycle of 28 days.	No
Secondary	Number of Events Which Led to Hospitalization	The events (reasons) for hospitalizations such as infection, transfusion, acute choleycystitis, allergic transfusion reaction, dyspnoea with right pleural effusion, febrile neutropenia, fever, for decitabine, Myelodysplastic Syndrome (MDS) hematuria, paronychia, pneumonia, heart failure, peri-anal abscess (PAA), pancytopenia,fluctuated neutropenia fever, right dorsal foot cellulitis, Right lower (Rt.Lw) lung pneumonia with impending respiratory (resp) failure, Serious adverse event (SAE)+schedule hospitalization for decitabine, septic shock and not available were reported.	Start of treatment until disease progression or death or up to Cycle 8, each cycle of 28 days	No
Secondary	Quality of Life Assessment	The quality of life was assessed by the questionnaire QLQ C-30 designed by European Organization for the Research and Treatment of Cancer (EORTC). EORTC QLQ-C30 is a 30-item questionnaire to assess the overall quality of life in cancer participants. Most questions used 4-point scale (1=Not at All' to 4=Very Much') and 2 questions: Q29 on overall health and Q30 on overall quality of life uses 7-point scale ranging from 1=Very Poor to 7=Excellent. Higher score indicates better quality of life.	Day 1 of Cycle 1 and Cycle 8 (each cycle of 28 days)	No
