Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The trial was designed to evaluate the incidence of unintended hypophosphatemia (low level of phosphate in the blood) in subjects with iron deficiency anaemia (IDA).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This trial was designed to evaluate the effect of IV iron isomaltoside/ferric derisomaltose compared with IV ferric carboxymaltose on s-phosphate in subjects with IDA caused by different etiologies.

The subjects received either a single intravenous (IV) dose of iron isomaltoside/ferric derisomaltose (1000 mg at baseline) or two IV doses of ferric carboxymaltose (one dose 750 mg at baseline and a second dose 750 mg on day 7; cumulative dose: 1500 mg). The study subjects were monitored for up to 35 days from baseline.

Iron isomaltoside/ferric derisomaltose

Administered IV

Group Type EXPERIMENTAL

Iron isomaltoside/ferric derisomaltose

Intervention Type DRUG

Iron isomaltoside/ferric derisomaltose (Monofer®/Monoferric®; 100 mg/mL) was the test product in this trial.

The dose of iron isomaltoside/ferric derisomaltose for the individual subject was a single IV infusion of 1000 mg (10 mL containing 1000 mg iron isomaltoside/ferric derisomaltose diluted in 100 mL 0.9 % sodium chloride), given over approximately 20 minutes (50 mg iron/min) at baseline (cumulative dose: 1000 mg).

Ferric carboxymaltose

Administered IV

Group Type ACTIVE_COMPARATOR

Ferric carboxymaltose

Intervention Type DRUG

Ferric carboxymaltose (Injectafer®; 50 mg/mL) was the comparator in this trial. The dose of ferric carboxymaltose for the individual subject was 750 mg, infused over at least 15 minutes at baseline and on day 7 (cumulative dose: 1500 mg).
