E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary efficacy objective of the study is to evaluate the relationship between best bone marrow blast response and overall survival in MDS patients with excess blasts (5-30%) progressing on or after treatment with azacitidine or decitabine. Bone marrow blast response is defined as BM complete response (BMCR), ≥ 50% BM blast decrease from pretreatment value, or stable BM response (no progression) according to the International Working Group (IWG) 2006 criteria. |
|
E.2.2 | Secondary objectives of the trial |
• Overall response (complete remission [CR], partial remission [PR], bone marrow complete response [BMCR], and stable disease [SD]) according to 2006 IWG criteria;
• Hematological improvements (erythroid response [ER], platelet response [PLR] and neutrophil response [NR]) according to 2006 IWG criteria;
• Improvements of cytogenetics as evaluated by the change in aneuploidy in BM according to 2006 IWG criteria;
• Progression-free survival;
• Transition time to AML, where AML is defined as follows:
- Increase of at least 50% BMBL, and more than 20% BMBL for RAEB-1 and RAEB-2 and CMML patients;
- Increase of at least 50% BMBL for RAEB-t patients;
• Quality-of-life (QOL) scores (using EORTC Quality of Life Questionnaire [QLQ]-C30 version 3;
• Incidence of infections requiring treatment with IV antimicrobials and of bleeding episodes.
• Population pharmacokinetics. |
