iron isomaltoside 1000 (monofer®) administered by a high dosing regimen in subjects with inflammatory bowel disease

Conditions: Inflammatory Bowel Disease

Summary: the study is a prospective, non-controlled, open-label multi-centre pilot safety study of iron isomaltoside 1000 (monofer®) administered to subjects with anaemia and inflammatory bowel disease (ibd). based upon haemoglobin (hb) level, the subjects are divided into two treatment groups, a and b. depending on the body weight, subjects in treatment group a will receive a total dose of 1,500 mg or 2,000 mg iv iron isomaltoside 1000 as a single infusion, whereas subjects in treatment group b will receive a total dose of 2,500 mg or 3,000 mg iv iron isomaltoside 1000 divided into two administrations.

subjects with a diagnosis of ibd (crohn's disease or ulcerative colitis) and ida ( iron deficiency anaemia) with or without concomi-tant inflammation will be enrolled to receive a high dose of iv iron isomaltoside 1000.
