Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients are recruited from the Heart Failure Clinic at Concord Hospital. Patients with iron deficiency will be approached by the investigator regarding their interest in participation and informed consent will be obtained prior to their enrollment. Participating patients will present to the Concord Hospital Cardiovascular Outpatient department on the day of their infusion, where an independent clinical trial pharmacist will randomize the patient using a computer software program to iron or placebo. The investigators will not know which treatment is allocated to the patient
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
At randomization, the pharmacist will use a computer software to randomize the patient to either iron or placebo, stratified by their NYHA class (I vs II and III). The details on which treatment the patient received will be entered into a separate database that will not be made available to the investigators, ensuring they are blinded to what treatment the patients are having
Masking / blinding

Other design features
Ferric carboyxmaltose is easily distinguished from normal saline due to its distinctive brown color. To ensure blinding of the patient, the treatment is administered with a curtain shielding the patient's view. To ensure blinding of the investigators, the treatment is administered by an independent nurse not involved in data analysis.
Phase
Phase 2
Type of endpoint/s
Efficacy
Statistical methods / analysis
The primary outcome is an improvement in 2 week change in KCCQ score greater or equal to 5, which is considered a clinically significant change. Assuming a standard deviation of change in KCCQ of 8, a sample size of 82 patients (41 treatment, 41 placebo) will have 80% power to detect a between group change in KCCQ score of 5 or greater. We will also arrange for an outside statistician to conduct a blinded interim analysis after 20 patients per group have been enrolled to revise the sample size requirement and ensure that we have the power to show a clinically significant difference of 5 points between groups is statistically significant. We will analyze the outcomes with an ANCOVA model on the change in KCCQ score, PHQ-9 score, BNP, ST2 at 2 weeks. A repeated measures mix model will be used for changes in 6-minute walk test, hand grip strength, cardiac output, cardiac index, and stroke volume. We have pre-specified subgroups including NYHA class (I vs II/III), left ventricular ejection fraction (normal vs reduced), gender, anaemia (haemoglobin greater or equal to 12g/dL vs <12g/dL), diabetes, and estimated glomerular filtration rate (greater or equal to 60ml/min/1.73m2 vs <60 ml/min/1.73m2) for further analysis to identify interactions.
