E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to evaluate and compare the effect of IV iron isomaltoside to a fixed dose of oral iron administered as tablet ferrous fumarate with ascorbic acid as avoidance of developing/having IDA throughout the duration of the trial in pregnant women who have ID after 4 weeks of standard oral treatment. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to compare the effect of IV iron isomaltoside and oral ferrous fumarate with ascorbic acid on: • Hb and other haemathological indices of IDA in maternal blood • Maternal fatigue • Maternal Quality of Life (QoL) • RLS • Need for an additional IV iron isomaltoside dose rescue medication with IV iron or rescue red blood cell (RBC) transfusion
The safety objective is to compare the safety of iron isomaltoside to oral iron.

E.4 | Principal exclusion criteria |
1. History of anaemia caused by e.g. thalassemia, hypersplenism or haemolytic anaemia (known haematologic disorder other than iron deficiency) 2.

Known hypersensitivity to any excipients in the investigational drug products 5. History of active asthma within the last 5 years 6. History of multiple allergies 7. Known decompensated liver cirrhosis or active hepatitis 8. Active acute or chronic infections (assessed by clinical judgement) 9. Rheumatoid arthritis with symptoms or signs of active inflammation 10. Treated with IV iron products or blood transfusion within 4 weeks prior to inclusion 11. Treated with erythropoietin (EPO) within 4 weeks prior to inclusion 12. Participation in any other interventional trial where the trial drug has not passed 5 half-lives prior to inclusion 13. Any other medical condition that, in the opinion of the Investigator, may cause the subject to be unsuitable for the completion of the trial or place the subject at potential risk from being in the trial 14. Meeting RBC-transfusion criteria (Hb ≤6.9 g/dL= 4.3 mmol/L with intolerable symptoms of anaemia like severe palpitations, severe dizziness, shortness of breath at rest or syncope or an Hb ≤ 6.4 g/dL (4.0 mmol/L) without intolerable symptoms of anaemia) 15. Multiple pregnancies 16. Inability to read and understand the Danish language

E.5 End points |
E.5.1 | Primary end point(s) |
• Achievement of an Hb ≥11.0 g/dL (≥ 6.8 mmol/L) at all post-baseline time points |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Any time within 18 weeks after beginning of treatment. |
|
E.5.2 | Secondary end point(s) |
• Hb ≥11.0 g/dL (≥6.8 mmol/L) at T3w, T6w, T12w, and T18w • Change in Hb, reticulocytes, reticulocyte haemoglobin content (CHr), s-ferritin, s-transferrin, s-iron, hepcidin, and calculated transferrin saturation (TSAT) from baseline to T3w, T6w, T12w, and T18w • Incidence of hypophosphatemia (defined as serum [s] phosphate <2 mg/dL) at any time post-baseline to T18w) • Change in fatigue (FACIT-fatigue scale) from baseline to T3w, T6w, T12w, and T18w • Change in QoL (Short Form (SF) -12) from baseline to T3w, T6w, T12w, and T18w • Presence of RLS (using four diagnostic criteria) at T3w, T6w, T12w, and T18w • Number of subjects who receive an additional IV iron isomaltoside dose at T6w and/or T12w • Reason for the additional IV iron isomaltoside dose (non-compliance, lack of effect) • Number of subjects who received 1 or more allogenic RBC-transfusions and the number of units of RBC-transfused per transfused subject from baseline to final subject visit • Type and incidence of AEs including adverse drug reactions (ADRs) and any suspected unexpected serious adverse events (SUSAR) • Serious or severe hypersensitivity reaction starting on or after the first dose of randomized treatment (i.e. treatment emergent). The hypersensitivity terms are defined as standardised Medical Dictionary for Regulatory Activities query (SMQ) terms (including four additional terms). • AEs of special interest: constipation, diarrhoea, flatulence, nausea, vomiting, abdominal pain, dyspepsia, dysguesia, and stool discoloration • Number of subjects who discontinue from the trial because of lack of response or intolerance of investigational drugs • Foetal bradycardia related to an additional IV iron isomaltoside infusion at or after GA 26 • Change in biochemical safety parameters from baseline to T3w, T6w, T12w, and T18w • Compliance to treatment: at baseline in the IV group and by pill-count at T6w and T18w in oral group
In addition, physical examinations and measurements of vital signs, height, weight, and safety laboratory parameters will be measured as part of standard safety assessments. |
