- Brief Summary
Evaluate safety and efficacy of iron isomaltoside/ferric derisomaltose (Monofer®/Monoferric®) compared with iron sucrose (Venofer®), in subjects diagnosed with IDA.
- Detailed Description
IDA is highly prevalent condition in subjects with cancer and gastrointestinal diseases such as inflammatory bowel diseases, menstruating or pregnant women, and subjects who have undergone bariatric procedure or surgery. IDA can have a substantial medical and quality of life (QoL) burden. Treatment of subjects diagnosed with IDA includes controlling the bleeding and replenishing lost iron.
This study was designed to evaluate the safety and efficacy of iron isomaltoside/ferric derisomaltose compared with iron sucrose in subjects diagnosed with IDA. In a subfraction of 35 subjects treated with iron isomaltoside/ferric derisomaltose, ECG and iron will be frequently measured.
The study subjects received either a single intravenous (IV) dose of iron isomaltoside/ferric derisomaltose (1000 mg at baseline) or iron sucrose (200 mg IV injections at baseline and repeated according to standard practice or physician choice up to a maximum of five times within the first two weeks starting at baseline; a cumulative dose of 1000 mg was recommended). The study subjects were monitored for up to 8 weeks from baseline.

- Primary Outcome Measures
Name Time Method Change in Hemoglobin (Hb) From Baseline to Week 8 Baseline to week 8 Efficacy
Evaluate the effect on the hemoglobin (Hb) level following treatment with iron isomaltoside/ferric derisomaltose vs iron sucrose in subjects with iron deficiency anaemia (IDA) .
Response was defined as change from baseline in hemoglobin (Hb) to week 8, i.e. ability to increase Hb in subjects with IDA, when oral iron preparations were ineffective or could not be used or in whom the screening Hb measurement in Investigators' opinion were sufficiently low to require rapid repletion of iron stores.Incidence of Protocol-defined Serious or Severe Hypersensitivity Reactions Baseline to week 8 Safety
For this endpoint, the number of participants with serious or severe hypersensitivity reactions were evaluated. The hypersensitivity reactions that were included in the analysis were those that started on or after the first dose of randomised treatment (i.e. treatment emergent). The terms used to define hypersensitivity were those specified by the Standardised MedDRA Queries (SMQ) for hypersensitivity, plus four additional terms: loss of consciousness, seizure, syncope, unresponsiveness.
The potential hypersensitivity AEs were adjudicated in a blinded fashion by an independent Clinical Endpoint Adjudication Committee (CEAC).
Results show only those participants that had adjudicated and confirmed serious or severe hypersensitivity reactions.
- Secondary Outcome Measures
Name Time Method S-phosphate <2 mg/dL at Any Time From Baseline to Week 1, 2, 4, and 8 Baseline, week 1, 2, 4, and 8 Safety
Results show the number of subjects who had s-phosphate \<2 mg/dL at any time from baseline to week 1, 2, 4, or 8.Composite Cardiovascular Adverse Events (AEs) Baseline, week 1, 2, and 8 Safety
Results show the composite cardiovascular adverse events (AEs), that started on or after the first dose of randomised treatment (i.e. treatment emergent) up to week 8.
The reported potential cardiovascular AEs were adjudicated in a blinded fashion by an independent Clinical Endpoint Adjudication Committee (CEAC).
The potential cardiovascular AEs included the following:
* Death due to any cause
* Non-fatal myocardial infarction
* Non-fatal stroke
* Unstable angina requiring hospitalisation
* Congestive heart failure requiring hospitalisation or medical intervention
* Arrhythmias
* Hypertension
* Hypotension
Results show only those participants that had adjudicated and confirmed treatment-emergent composite cardiovascular AEs.Time to First Composite Cardiovascular Safety AE Baseline, week 1, 2, 4, and 8 Safety
Time to first composite cardiovascular AE was defined as the actual time in days from first dose of treatment until the date of the composite cardiovascular AE. For subjects not reporting a composite cardiovascular AE, the time was censored at the date of the last attended visit. Only the adjudicated and confirmed composite cardiovascular safety AEs, as judged by the CEAC, were considered for this endpoint.
Time to first composite cardiovascular AE was defined as the actual time in days from first dose of treatment until the date of the composite cardiovascular AE. For subjects not reporting a composite cardiovascular AE, the time was censored at the date of the last attended visit.S-Ferritin Concentration of ≥100 ng/mL and Transferrin Saturation (TSAT) of 20-50% at Any Time From Week 1 to Week 8 Week 1 to week 8 Efficacy
Proportion of subjects reaching the composite endpoint of s-ferritin concentration ≥100 ng/mL and TSAT of 20-50% at any time from week 1 to 8.Change in Hb Concentration From Baseline to Week 1, 2, and 4 Baseline, week 1, 2, and 4 Efficacy
Change in Hb concentration from baseline to week 1, 2, and 4.Change in S-ferritin Concentration From Baseline to Weeks 1, 2, 4, and 8 Baseline, week 1, 2, 4, and 8 Efficacy
Change in s-ferritin concentration from baseline to weeks 1, 2, 4, and 8.Change in Transferrin Saturation (TSAT) From Baseline to Week 1, 2, 4, and 8 Baseline, week 1, 2, 4, and 8 Efficacy
Changes in transferrin saturation (TSAT) from baseline to week 1, 2, 4, and 8.
TSAT is the value of serum iron divided by the total iron-binding capacity and the unit is %, which referrers to % of iron-binding sites of transferrin being occupied by iron.Change in Concentrations of Serum Iron (S-iron) From Baseline to Week 1, 2, 4, and 8 Baseline, week 1, 2, 4, and 8 Efficacy
Changes in the concentrations of serum iron (s-iron) from baseline to week 1, 2, 4, and 8.Hb Concentration Increase of ≥2 g/dL From Baseline to Week 1, 2, 4, and 8 Baseline, week 1, 2, 4, and 8 Efficacy
Results show responders to the treatment. A subject was considered a Hb responder to a certain week if an increase in Hb of at least 2 g/dL from baseline to the week in question was observed (week 1, 2, 4, and 8).Time to Change in Hb Concentration ≥2 g/dL Baseline, week 1, 2, 4, and 8 Efficacy
Time to change in Hb concentration ≥2 g/dL. Subjects who achieved Hb concentration increase of ≥2 g/dL (from baseline to week 1, 2, 4, or 8).
For responders, time to Hb response was defined as the scheduled time from baseline until the visit where the first Hb response was measured.Hb Concentration of >12 g/dL at Any Time From Week 1 to Week 8 Week 1 to week 8 Efficacy
Hb concentration of \>12 g/dL at any time from week 1 to week 8.

Results show the number of participants who achieved Hb concentration increase of ≥2 g/dL at any time from week 1 to week 8.Change in Fatigue Symptoms From Baseline to Week 1, 2, and 8 Baseline, week 1, 2, and 8 Efficacy
Change in fatigue symptoms from baseline to week 1, 2, and 8 was measured by the Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Scale.
The Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Scale consisted of 13 items ranging from 0 (not at all) to 4 (very much), except items #7 and #8 which are reversed scored. The total score range is 0-52.
A score of less than 30 indicated severe fatigue, and the higher the score, the better outcome/quality of life (QoL). If more than 50% of the items for a subject at a given visit were missing, the total score was not calculated.
Total score was calculated as shown below:
Total score= Sum of individual scores x 13 / Number of items answeredIntervals in Screening for Diabetic Retinopathy (ISDR) Questionnaire, Cost of Public Transport/Taxi And Parking Baseline Pharmacoeconomics
