Details and patient eligibility

About

The scientific rationale for this study is the evolving understanding that iron-induced tissue damage is not only a process of progressive bulking of organs through high-volumes iron deposition, but also a reactive iron species related "toxic" damage.

Iron mediated damage can occur prior reaching high iron storage thresholds derived from thalassemia major setting, free toxic iron species being already present when transferrin saturation >60-70% (25); therefore a timely early adoption of iron chelation may be of benefit before overt iron overload is seen.

Our hypothesis is that early and low dose DFX-FCT is better tolerated and is able to prevent iron accumulation and consequently tissue iron related damage, by consistently suppressing iron reactive oxygen species (NTBI and LPI).

If this hypothesis is confirmed this approach could contribute to an improvement of clinical practice of patients managements. Additionally this approach might also be a contribute in preventing future iron overloaded related complication, in this already frail and co-treated patient population.

Exclusion criteria

Patients aged <18 years old
Higher risk (revised IPSS) MDS (Intermediate 2, high)

Creatinine Clearance (CrCL): <60 ml/min. Patients with CrCl of 40-60ml/min will be included only individually if no other renal risk factors are present.
Serum creatinine >2 x ULN at screening. If borderline serum creatinine will be measured within 7-10 days and the mean value will be used for eligibility criteria.
Significant proteinuria as indicated by a urinary protein/creatinine ratio > 0.5 mg/mg in a non-first void urine sample (or alternatively in two of three samples obtained for screening).
ECOG performance status >2.
Left ventricular ejection fraction < 50% by echocardiography
A history of repeated hospitalization for congestive heart failure.
Systemic diseases that would prevent study treatment (e.g. uncontrolled hypertension, cardiovascular, renal, hepatic, metabolic, etc.)
Clinical or laboratory evidence of chronic Hepatitis B or Hepatitis C (definition of chronic hepatitis follows EASL 2017 criteria).
History of HIV positive test result (ELISA or Western blot).
Treatment with systemic investigational drug within 4 weeks or topical investigational drug within 7 days of study start.
ALT or AST over 3 times superior to ULN at screening.
ANC < 500/ microL
Platelets transfusion dependency
Total bilirubin over 1.5 times superior to ULN at screening (patients with Gilbert syndrome are allowed to enter the study)
Diagnosis of Child score C liver cirrhosis.
Patients participating in another clinical trial other than an observational registry study.
Patients with a history of another malignancy within the past 3 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, intending-to-become pregnant, or breast-feeding patients.
Women of potential maternity age who do not agree to practice effective contraceptive methods fo the entire study duration.
History of drug or alcohol abuse within the 12 months prior to enrollment.
Hypersensitivity to the active substance or to any of the excipients.
Inability to provide a valid informed consent
