E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to evaluate deferasirox and placebo with regard to event-free survival (a
composite primary endpoint including death and non-fatal events related
to cardiac and liver function and transformation to AML) in low and int-1
risk MDS patients with transfusional iron overload.. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate:
• Hematologic improvement (HI) in terms of erythroid response
• Overall survival
• Change in endocrine function (thyroid and glycemic control)
• Disease progression (which includes MDS progression and progression
to AML)
• Change in serum ferritin level
• Change in cardiac function
• Frequency of infections requiring intravenous antimicrobials
• Safety, in particular to assess the levels of increased risk for prespecified
adverse events (renal dysfunction, neutropenia,
thrombocytopenia, gastrointestinal bleeding, and laboratory
abnormalities) that would be clinically unacceptable in the context of the
level of benefit that is likely to be provided by iron chelation using
deferasirox in MDS patients with iron overload (see Fleming 2008 for
general approach) |

the central reading assessment

uncontrolled hypertension, cardiovascular, renal, hepatic(including
Child-Pugh Class B and C) , metabolic,
etc.)

(HBsAg in the absence of HBsAb OR HCV Ab positive with HCV RNA
positive)

investigational drug within 7 days of study start
• ALT or AST > 3.5 × ULN at screening

• Diagnosis of liver cirrhosis (either established diagnosis or diagnosis
by liver biopsy or central ultrasound reading)
• Patients participating in another clinical trial other than an
observational registry study
• Patients with a history of another malignancy within the past five
years, with the exception of basal skin carcinoma or cervical carcinoma
in situ or completely resected colonic polyps carcinoma in situ.
• History of non-compliance to medical regimens, or patients who are
considered potentially unreliable and/or not cooperative
• Presence of a surgical or medical condition which might significantly
alter the absorption, distribution, metabolism or excretion of study drug
• Pregnant, or breast-feeding patients, or patients of child-bearing
potential not employing an effective method of birth control (see
Women of child-bearing potential, below, for further details regarding
effective methods of birth control).
• History of drug or alcohol abuse within the 12 months prior to
enrollment |
