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.

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 |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change of hepatic iron | Change of hepatic iron from the baseline according to baseline hepatic iron level: For patients with baseline LIC =5 mg/g dry weight (dw) ± 1.5 mg/g dw. For patients with baseline LIC >5 mg/g dw ±20% | 1 year | |
Secondary | Definition of iron overload | The baseline iron status of MDS patients at the beginning of their transfusion story is today unknown. This study is the first unbiased and direct measurement of iron stress and oxidative stress in MDS patients at the beginning of the transfusion story.
Baseline iron status will be described by classical iron markers: serum ferritin (ng/ml), transferritin saturation (%), liver and pancreas iron concentration by MRI (mg/g dry weight). Total body iron stores will be calculated (mg/kg) with the published formula (N Engl J Med 2000; 343:327-331). Tissue reactive oxygen species will be measured in the patient's plasma as follows: non-transferrin bound iron= micromoles/L, Labile Plasma Iron= micromoles/L. Oxidative stress will be measured by Malonildialdehyde (MDA). Levels in plasmas= micromoles/L. |

Secondary | Efficacy of treatment | Absolute change in hepatic iron concentration EOS versus baseline. | 1 year | |
Secondary | Evolution of iron overload serologic markers | Absolute and relative changes in serum ferritin and transferrin saturation from baseline to every visit during the whole treatment period | 1 year | |
Secondary | Evolution of toxic serum iron forms | Presence and quantitative evolution of toxic serum iron forms (iron tissue reactive species) under low dose DFX therapy | 1 year | |
Secondary | Relationship between NTBI and LPI with serum ferritin and liver and pancreas iron overload | Prevention of iron overload will be studied by the difference iron parameters end of therapy - baseline by liver iron concentration (mg/g dry weight), pancreas iron concentration (mg/g dry weight), total body iron stores (mg/kg) calculated the N Engl J med 2000 343:327-331 formula = liver iron concentration x 10.6.
Serum ferritin = ng/ml. Relationship between suppression of tissue iron species and prevention of iron accumulation (observational study) will be measured by the: NTBI/LPI values (micromoles/L), Differences end of study - baseline quantitative parameters of iron loading (liver and pancreas iron concentration and total body iron stores). |

Secondary | Costs analysis | Treatment cost will be compared with standard approach cost (14 mg/kg/day. DFX-FCT after 20 units of packed red cells units and serum ferritin> 1000 ng/ml over one year of treatment). For comparison literature and matched FISM registry data will be used. Unit of measurement will be 2019 USD and Euros. | 1 year | |
Secondary | Study of biological cellular damage | Biological cellular damage will be measured by presence and level of oxidative stress determined at baseline, during and at end of study and compared with ongoing treatment by: Malonildialdehyde (MDA) plasma levels (micromoles/L). | 1 year |
