Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
An intervention will be used, as per the protocol document (also described below).

The population being studied is all female athletes with iron deficiency, half of whom will be randomised to treatment of their iron deficiency. The comparators will be the interventions before and after randomisation of treatment.

Intervention description: Iron treatment (single injection; ~90 minutes).

Participants who conform to all eligibility criteria and have provided written informed consent will be randomised to receive either intravenous iron or placebo.

Intervention will take place at the WA Iron Centre (374 Belgravia street, Cloverdale), under the clinical care of Dr. Pradeep Jayasuriya (AHPRA: MED0001577032; Provider number: 002079AY).

Administration will be given in a registered clinic (as described above) with appropriate resuscitation facility and staff available in the event of an emergency. Participants will be administered the study medication by the unblinded person. For the drug administration the patient will have an intravenous line sited. Following this it is advised that the skin along the donor vein will be wiped using an iodine swab to help maintain the blind. The patient is to be shielded from seeing preparation of the study drug, drug administration, disconnection and removal of the intravenous line. Participants should be closely monitored as per clinic protocols throughout administration of the treatment.

1. Monofer group: 1000 mg of iron isomaltoside will be administered as an intravenous infusion (100ml n/saline) over a minimum of 15 minutes using a black infusion kit.

2. Placebo group: Normal saline will be administered as an IV infusion (100ml n/saline) over a minimum of 15 minutes using a black infusion kit.

Adverse events occurring in connection with the administration of study medication will be recorded. In the event of a patient having an allergic reaction or signs of intolerance during study drug administration, the investigator must follow local protocols. If appropriate, the investigator should complete and submit a serious adverse event (SAE) report as per trial protocol. It should be noted that adverse events will not be assessed as an outcome for the current study.

If the treatment is stopped for other reasons and the patient is willing, then treatment can be restarted where possible (as per local practice).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
We use an online randomisation and allocation system.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A commonly used independent internet-based service (www.sealedenvelope.com) will assign participants randomly to either IV iron or placebo in a 1:1 ratio. Staff involved in recruiting participants will access the system using a password and PIN code.

There will be no minimisation or stratification protocol planned as numbers in this study are small.

Statistical methods / analysis
Statistical analysis will be performed using the Statistical Package for the Social Sciences (SPSS) version 25.0 (IBM, Inc., New York, NY). A multivariate analysis of variance (MANOVA-treatment and time) will be used to detect any significant changes in iron status and exercise-test performance. In the event of a significant main effect, a post hoc independent t-test will be used to analyse between- group differences. ANCOVA analysis will also be used to detect any significant changes in the outcome variables (both primary and secondary). Covariates will include training load and menstrual cycle. Results will be expressed as mean and standard deviation unless otherwise stated. Significance will be considered as p < 0.05.
