About

Treatment with iron isomaltoside and ferric carboxymaltose in subjects with iron deficiency anaemia due to inflammatory bowel disease and comparison of the incidence of hypophosphatemia

Full description

Existing IV iron complexes differ in relation to the compounds capability to induce unintended hypophosphatemia to a degree defined as medical significant.

This trial is designed evaluate the effect of IV iron isomaltoside compared to IV ferric carboxymaltose on phosphate in subjects with IDA due to inflammatory bowel disease .

Enrollment: 97 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria include:

• Men or women ≥ 18 years

• S-phosphate > 2.5 mg/dL
• Oral iron preparations are ineffective or cannot be used or where there is a clinical need to de-liver iron rapidly
• Willingness to participate and signing the Informed Consent Form (ICF)

Exclusion Criteria include:

• Anaemia predominantly caused by factors other than IDA according to Investigator's judgment
• Hb ≥ 10 g/dL and body weight < 70 kg
• Hemochromatosis or other iron storage disorders
• Known hypersensitivity reaction to any component of iron isomaltoside or ferric carboxymaltose
• Previous serious hypersensitivity reactions to any IV iron compounds
• Treatment with IV iron within the last 30 days prior to screening
• Treatment with erythropoietin or erythropoietin-stimulation agents, red blood cell transfusion, radiotherapy, and/or chemotherapy within the last 30 days prior to screening
• Received an investigational drug within the last 30 days prior to screening

• Untreated hyperparathyroidism
• Kidney transplantation
• Conditions that interfere with the subject's ability to understand the requirements of the trial and/or presumable non-compliance
• Any other laboratory abnormality, medical condition, or psychiatric disorders which, in the opinion of the Investigator, will put the subject's disease management at risk or may result in the subject being unable to comply with the trial requirements
• Pregnant or nursing women.
