E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Chronic Kidney Disease stages 3b to 5 with iron deficiency |
|
E.1.1.1 | Medical condition in easily understood language |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether IV iron supplementation in iron deficient non-anaemic CKD patients improves physical and functional status assessed by the 6MWT and questionnaires (KDQoL and MLHF). |
|
E.2.2 | Secondary objectives of the trial |
Improvement in cardiac structure and function. Monitoring of physiological aspects using pulse oximetry and cardiac harness for heart and respiratory rate.
Change in New York Heart association functional classification (NYHA)
To investigate cardiac iron loading based on MRI using T2* in a small cohort of patients in a single centre (10 patients)
To observe improvement in renal function as assessed with eGFR |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
In a separate sub-study, to be performed at Hull and East Yorkshire Hospitals NHS Trust 10 patients will undergo T2* imaging of the heart to assess iron loading of the heart immediately after iron infusion. This is not to examine Monofer® as a tracer substance but direct loading into cardiac myoctyes. Each patient’s baseline data will serve as a control. |
|
E.3 | Principal inclusion criteria |
Stage of CKD will be calculated by the 4 point MDRD equation. Patients must have a stable eGFR, as defined by <20% variation in eGFR in the preceding 3 months. It is estimated that approximately 30% of patients will have underlying ischaemic heart disease and be on aspirin therapy, which may contribute to iron deficiency. In both groups, BP will be controlled in participants in the trial to the target pressures outlined by the NICE Hypertension guideline (clinical guideline number 127) and NICE CKD guideline (clinical guideline number 73) (21, 22). The standard blood pressure targets will be used (<140/85mmHg)
Patients with established CKD (Stages 3b-5) (eGFR using MDRD <45ml/min/1.73m2), not on dialysis.
Clinically stable (principal investigator’s judgement)
Resting BP ≤ 160/90mmHg when measured in accordance with British Hypertension Society guidelines.
Men and women aged 18-80 years
Able to give a written and signed informed patient consent
Serum ferritin level less than 100 µg/L AND/OR transferrin saturation ≤20%
Patient must be in sinus rhythm to allow for accurate echo measurements
Haemoglobin greater or equal to 110g/L up to and including 150g/L
If deemed necessary all patients will have had faecal occult blood testing (FOBs) carried out as part of national recommendations to exclude bowel pathology.
|
|
E.4 | Principal exclusion criteria |
Pregnancy or breast feeding (To avoid pregnancy, women have to be postmenopausal, (at least 12 months must have elapsed since last menstruation), surgically sterile, or women of child bearing potential must use one of the following contraceptives during the whole study period and after the study has ended: Contraceptive pills, intrauterine devices (IUD) contraceptive depot injections (prolonged release gestagen), subdermal implantation, vaginal ring and transdermal patches.
Age < 18 years
Known allergy to iron therapy
Haemochromatosis or history of acquired iron overload
Parenteral iron therapy within the previous 6 weeks
Inability to co-operate with study protocol
CRP > 50 mg/L
Active infection
Symptomatic ischaemic heart disease
Current therapy with ESA agents
Patients with atrial fibrillation
Patients with potential confounding factors - cancer, (with exception of basal cell or squamous cell carcinoma of the skin, and cervical intraepithelial neoplasia)
Patients who are unable or do not wish to give consent.
Patients being investigated for potential blood loss
Patients who have received blood transfusions
Patients with known haemoglobinopathy, myelodysplasia, myeloma,
Patients with musculoskeletal disease, who the investigator deems unable to carry out the 6MWT.
Patients who have been involved in another medicinal trial (CTIMP) within the past four weeks
