E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1) To demonstrate superiority of i.v. iron substitution with Polyglucoferron compared to oral iron therapy with Ferrous sulfate in focus on proportion of patients who achieve normalized Hb-levels (according to WHO definition) or increased Hb-level with at least 1.5 g/dl 28 days at visit 4 compared to BL
2) To demonstrate superiority in short term safety assessed of statistically significant lower levels of volume-corrected urine iron, estimated by the difference in v.c. iron urine measured before and after i.v. administration (first urine after the end of i.v. administration) of Polyglucoferron compared to Ferric Carboxymaltose |
|
E.2.2 | Secondary objectives of the trial |
•Treatment effects on changes in haematologic and serologic iron parameters (Hb,TSAT,s-iron,s-transferrin,s-ferritin) from BL until V4 •Proportion of patients with normalization (WHO) of Hb at V4 •Treatment effects of Polyglucoferron i.v. and Ferric Carboxymaltose i.v. on s-phosphate levels at V4 •Overall tolerability and number, incidence, seriousness, severity and relationship of AEs/SAEs until 30d after last IMP •Changes in laboratory parameters, vital signs and physical exam on each visit incl. blood pressure and heart rate •AEs related to injection/infusion site reactions (i.v. groups) and hypersensitivity reactions •All-cause mortality until V4 •The need of allogenic RBC transfusion (number of units and number of patients) from BL until V4 •Treatment effect on change in Quality of Life (SF-36) at V4 compared to BL •Duration of hospital stay (days) until V4 •Analysis of total iron levels in plasma at BL after end of iron administration (for i.v. safety analysis group) |

Exclusion criteria related to Ferrous sulfate: • according to SmPC • hypersensitivity to any ingredient in the formulation • concomitant parenteral iron • haemochromatosis, and other iron overload syndromes
Exclusion criteria related to Ferric Carboxymaltose: • according to SmPC • hypersensitivity to the active substance, to Ferric Carboxymaltose or any of its excipients • known serious hypersensitivity to other parenteral iron products • anaemia not attributed to iron deficiency • evidence of iron overload or disturbances in the utilisation of iron
Exclusion criteria related to Polyglucoferron: • hypersensitivity to any ingredient in the formulation • known serious hypersensitivity to other parenteral iron products • anaemia not attributed to iron deficiency • evidence of iron overload or disturbances in the utilisation of iron |

E.5 End points |
E.5.1 | Primary end point(s) |
1) Proportion of patients who achieve normalized Hb-levels or increased Hb of at least 1.5 g/dl in the Polyglucoferron i.v. arm compared to oral iron substitution with Ferrous sulfate at visit 4 compared to BL
2) Pre-post difference of volume-corrected urine iron levels measured before and in the first urine after the end of i.v. administration, defined as short term safety surrogate marker after administration of the i.v. treatments, compared between Polyglucoferron and Ferric Carboxymaltose (volume corrected iron urine is defined as the ratio between urine iron and urine creatinine). |
