Brief Summary
This study will establish whether intravenous iron replacement has clinical benefit in idiopathic pulmonary arterial hypertension. A 24-week double-blind, randomised, placebo-controlled, crossover study will investigate whether a single dose of 1g of Ferinject® or CosmoFer improves cardiopulmonary haemodynamics, exercise capacity and quality of life and is well-tolerated.

Outcome Measures
Primary Outcomes (2)
Change in Exercise Capacity - Endurance
Time measured in seconds from start to end of the endurance bicycle cardiopulmonary exercise testing at 80% of the peak work rate. Peak work rate is determined by that achieved at the baseline incremental cardiopulmonary exercise test (CPET). Note that this was the primary end-point of the European study. Endurance CPET was not done in China.
12 Weeks post study treatment
Change in Resting Pulmonary Vascular Resistance (PVR)
To be measured by cardiac catheterisation in wood units.
12 weeks post study treatment
Secondary Outcomes (30)
Oxygen Consumption (VO2) Level at Peak 12 Weeks After Study Treatment
12 weeks post study treatment
Oxygen Consumption (VO2) at Metabolic Threshold
12 weeks post study treatment
Ventilation / Volume of Exhaled Carbon Dioxide (VE/VCO2 Slope)

Eligibility Criteria
You may not qualify if:
- Unable to provide informed consent.
- Clinically-significant renal disease (Creatinine clearance \< 30 ml/min per 1.73 m2 calculated from Chronic Kidney Disease-Epidemiology Collaboration (CKD-Epi) http://www.qxmed.com/renal/Calculate-CKD-EPI-GFR.php) or liver disease (including serum transaminases \> 3 times upper limit of normal).
- Haemoglobin concentration \<10 g/dl.
- Patients will be excluded if any single parameter (iron, ferritin or transferrin saturation) exceeds 1x upper limit of normal (ULN) in the local lab reference range.
- Patients with moderate to severe hypophosphatemia as defined as \<0.65mmol/L
- Known to have haemoglobinopathy e.g. sickle cell disease, thalassaemia.
- Admission to hospital related to PAH or change in PAH therapy within 1 month prior to Screening.
- Evidence of left ventricular disease or significant lung disease on high-resolution Computed Tomography (CT) scanning or lung function as judged by the investigator
- Acute or chronic infection or inflammation.
- Significant uncontrolled asthma as judged by the investigator, eczema or atopic allergies.
- Females who are lactating or pregnant.
- Individuals known to have Human Immunodeficiency Virus (HIV), Hepatitis B or C or Creutzfeld-Jakob disease.
- Known hypersensitivity to Ferinject® or any of its excipients.
- Evidence of disturbances in utilisation of iron.
- Significant blood loss (e.g. Gastro-intestinal bleed) within the last 3 months or history of menorrhagia.
