E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of iv iron repletion on skeletal muscle oxidative capacity as quantified by PCr t1/2 and ADP t1/2 following gastrocnemius muscle exercise using 31-P MRS. |
|
E.2.2 | Secondary objectives of the trial |
To determine:
• Change in skeletal muscle ferritin, free iron content, and transferrin receptor levels from baseline to 2 weeks post
treatment.
• Change in skeletal muscle fibre type, immunohistochemistry, and aerobic enzyme levels from baseline to 2 weeks
post treatment.
• Change in distance walked in 6 minutes from baseline to 2 weeks post treatment.
• Change in symptom status from baseline to 2 weeks post treatment.
• Change in haematological and biochemical indices from baseline to 2 weeks post treatment.
• Number and incidence of adverse events; changes in liver function tests and renal function tests; changes in vital
parameters. |

• On optimal conventional therapy for at least 4 weeks prior to recruitment and without dose changes for at least 2 weeks.
• Screening Hb concentration < 12 g/dl in females and < 13 g/dL in males (anaemic group, 50% of study population) or ≥12 g/dL in females and ≥ 13 g/dL in males (non-anaemic group, 50% of study population).

• Known hypersensitivity to parental iron preparations or any of their excipients.
• Known active infection, bleeding, malignancy, haemolytic anaemia, and rheumatoid arthritis.
• History of chronic liver disease with alanine transaminase (ALT) or aspartate transaminase (AST) >3 times the upper limit of the normal range, severe chronic lung disease with FEV1 < 50% predicted, myelodysplastic disorder, and known HIV/AIDS disease.
• Coagulopathy or anticoagulation with warfarin or warfarin substitutes for a metallic valve or an LV thrombus diagnosed in the last 6 months.
• Contraindications to magnetic resonance imaging (pacemaker, cardiac resynchronization therapy device, internal cardiac defibrillator, metal prostheses, excessive claustrophobia)
• Recipient of immunosuppressive therapy or renal dialysis.
• Anticipated need for erythropoietin or a blood transfusion during the study.
• Unstable angina as judged by the investigator, severe uncorrected non-functional valvular disease or left ventricular outflow obstruction, obstructive cardiomyopathy, uncontrolled fast atrial fibrillation or flutter (>110 bpm), uncontrolled symptomatic brady- or tachyarrhythmias.
• Musculoskeletal limitation that, in the investigators judgement, would impair exercise testing.
