Study summary

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

Read the detailed 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 .

Inclusion criteria

  • Men or women ≥ 18 years
  • Subjects diagnosed with IBD
  • \< 13 g/dL
  • Body weight ≥ 50 kg
  • S-ferritin \<100 ng/mL
  • ≥ 65 mL/min/1.73 m2
  • 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 Form (ICF)

Exclusion criteria

Exclusion Criteria include:

  • Anaemia predominantly caused by factors other than IDA according to Investigator's judgment
  • ≥ 10 g/dL and body weight \< 70 kg
  • Hemochromatosis or other iron storage disorders
  • Known 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 drug within the last 30 days prior to screening
  • Planned surgical procedure within the trial period
  • hepatic enzymes > 3 times
  • Surgery under general anaesthesia within the last 30 days prior to screening
  • Any non-viral infection within the last 30 days prior to screening
  • Alcohol or drug abuse within the past 6 months
  • 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.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 21, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
