About

The primary purpose of this study is to determine the effectiveness and safety of azacitidine in the treatment of Taiwanese subjects with higher-risk Myelodysplastic Syndrome (MDS).

Full description

The study has 3 phases which include the Screening Phase, the Treatment Phase, and the Post-Treatment Phase and outlined as follows:

Screening Phase:

Subjects will provide informed consent prior to undergoing any study-related procedures. Screening procedures are to take place within 28 days prior to the initiation of azacitidine treatment (Day 1, Cycle 1). Subject eligibility will be based on central pathology review. Bone marrow aspirate and bone marrow biopsy will be collected at screening and sent for morphological assessment by a central pathology reviewer prior to the subject receiving IP. The central pathology reviewer will document the MDS classification according to the FAB and WHO criteria (Appendix A and B, respectively).

A standard cytogenetic metaphase preparation will be prepared from the bone marrow aspirate and sent to the local or central laboratory (for sites without local analysis capability) for the cytogenetic analysis prior to receiving IP.

The IPSS score will be calculated using the central reviewer's pathology report for bone marrow blast percentage, local cytogenetic assessment for karyotype, and central laboratory report for number of cytopenias (Appendix D).

Treatment Phase:

The first dose of azacitidine for each subject begins on Day 1 of Cycle 1. All subjects will receive azacitidine 75 mg/m2/day SC for 7 days every 28 days for up to 6 cycles, unless they are discontinued from treatment. Visits during the treatment phase are to be scheduled weekly for the first 2 cycles, then every other week for all subsequent cycles throughout the rest of the study. Safety and efficacy measures are to be performed weekly, every other week, every 4 weeks, or at 24 weeks, depending on the procedure.

Post-Treatment Phase:

All discontinued subjects, regardless of reason for discontinuation, should undergo end-of-study procedures at the time of study discontinuation. Subjects will have a follow-up visit for the collection of adverse events up to 28 days after last IP dose.
