Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To study the effects of FCM on exercise tolerance in iron-deficient kidney transplant recipients (KTR’s).;Secondary Objective: To study the effects of FCM on haematinic parameters, quality of life, cardiac function, muscle function, bone and mineral parameters, focus, microbiota, the immune system, the incidence of infections, allograft failure and mortality in iron-deficient kidney transplant recipients (KTR’s).;Primary end point(s): The main study endpoint of the EFFECT-KTx study is change in exercise tolerance, quantified by the six-minute walk test (6MWT);Timepoint(s) of evaluation of this end point: After a maximum of four dosages of ferric carboxymaltose compared to placebo. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary study endpoints of the EFFECT-KTx study are changes, between t=0 and t=24 weeks and between the intervention and the control group, in: • Haematinic and iron parameters: haemoglobin, haematocrit, mean corpuscular volume (MCV), free serum iron, serum ferritin, serum transferrin, serum hepcidin and C-reactive protein • Systolic and diastolic cardiac function analysed with a transthoracic echocardiography measuring left ventricular ejection fraction (LVEF), diastolic function and strain; serum NTproBNP and high-sensitive troponin-T • Quality of life, assessed by the Short-Form-36 (SF-36) questionnaire, the Kidney Disease Quality of Life Test (KDQOL-SF), the Checklist Individual Strength (CIS) and the 5Dimensial EuroQol (EQ-5D) instrument • Muscle strength, measured by neurological physical examination of the major muscle groups, the ‘Five-Times-Sit-to-Stand-test (FTSTS), the Timed-up-and-Go test (TUG) and a handgrip dynamometry • Cognitive performance, measured by: the dutch version of the National Adult Reading Test, the Digit Span which is a component of the Wechsler Adult Intelligence Scale, a dutch version of the Rey Auditory Verbal Learning Test, the Cognitive Screening Test, the Trial Making Test, the Clock Drawing Test, the Word Fluency subtest of the Groninger Intelligentietest, the Controlled Oral Word Association Test, the Symbol Digit Modalities Test and the Key Search Test • Parameters of phosphate and bone metabolism: - Serum: phosphate, calcium, vitamin D, vitamin D3, parathyroid hormone, total FGF23 and intact FGF23 - 24-hour urine: phosphate, calcium • Characteristics of the immune system: peripheral blood mononuclear cell (PBMC) count, macrophage count, T-lymfocyte count, B-cell count, neutrophil count and analysis of cytokines • Hepatic parameters: serum aspartate aminotransferase and alanine aminotransferase • Parameters of kidney function and injury: - Blood: creatinin - Urine: MCD1, CD163 | — |
