Outcomes

Primary Outcome Measures

Incidence of Hypophosphatemia (S-phosphate Level <2 mg/dL)
Safety The incidence of hypophosphatemia (defined as s-phosphate <2 mg/dL) at any time from baseline up to day 35.

The time with hypophosphatemia was calculated as the actual number of days from the first day where s-phosphate was <2 mg/dL until the first day when s-phosphate was ≥2 mg/dL. If the subject did not reach s-phosphate ≥2 mg/dL, the subject was regarded as censored on day 35.

5. Study Description

Brief Summary
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
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.
