Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decline in renal function assessed by changes in eGFR (CKD-EPI equation) and change in serum bicarbonate assessed by a venous blood sample from baseline (Bs) and monthly to the end of the study (EOS) (12 months) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. All-cause mortality measured using patient records at the end of the study 2. ESRD measured using a blood sample for CKD-EPI Equation for Glomerular Filtration Rate (GFR) at baseline (Bs) and monthly to the end of the study (EOS). 3. Urinary albumin/creatinine ratio (RAC) measured from a spot urine sample at baseline (Bs) and monthly to the end of the study (EOS). 4. Serum albumin measured using blood sample at baseline (Bs) and monthly to the end of the study (EOS). 5. Serum soluble plasminogen activator urokinase receptor (suPAR) measured from a venous blood sample at baseline (Bs) and monthly to the end of the study (EOS). 6. Arterial stiffness measured by sphygmoCor technology (pulse wave analysis) at baseline (Bs) and monthly to the end of the study (EOS). Safety endpoints Percentage of patients who develop during the study: 1. Blood pressure >140/90 mmHg measured using a manual sphygmomanometer 2. Hypervolemia - peripheral edema or dyspnea with crackles (appreciated clinically and on auscultation with a stethoscope) or high blood pressure needing initiation or escalation of antihypertensive medication or diuretics measured using a manual sphygmomanometer 3. Hypokalemia 28 mEq/L measured using a blood sample 5. Calciphylaxis diagnosed by clinical presentation 6. Digestive symptoms (nausea, vomiting) by self report | — |
