Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients with stage II-IV CKD or with stage I CKD with an albumin-to-creatinine ratio in a first morning spot urine specimen of 100 mg/mmol, while on ACE-inhibition or on ARBs. 2. Serum phosphate levels between 0.80-1.45 mmol/l. 3. Not taking any phosphate binder therapy. 4. Providing informed consent.
Exclusion criteria
Exclusion criteria: 1. Patients taking medications or having concomitant illnesses likely to confound endpoint assessments (e.g. phosphate binder therapy, antiarrhythmic agents or anticonvulsants). 2. Patients with albumin-to-creatinine ratio > 100 mg/mmol not receiving ACE-inhibitors or ARB. 3. Women, who are pregnant or breastfeeding. 4. Change in vitamin D dose 4 weeks prior to baseline. 5. History of parathyroidectomy. 6. Hyperparathyroidism (e.g. PTH levels >2.5 upper normal) 7. History of arrhythmia or seizures. 8. Patients who have bowel obstruction, or malabsorption. 9. Posttransplant patients. 10. Body mass index > 35
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in C-terminal FGF-23 (Immutopics) in the highest dose of sevelamer compared to baseline for the entire cohort. | — |
Secondary
| Measure | Time frame |
|---|---|
| * Dose response relationship between C-terminal FGF-23 and sevelamer dose of the entire cohort. * Explorative variables: plasma levels of creatinine, phosphate, albumin, calcium, 25(OH)2D and 1,25(OH)2D3 and PTH. Urine: 24 hours phosphate excretion, TmP/GFR and proteinuria. | — |
