Design outcomes

Primary

MeasureTime frame
Uremic toxins (IS/pCS) Outcomes are assessed at baseline (Visit 2) and at Weeks 12, 16 to 18, and 24 after initiation of activated charcoal (5 g/day) Protein bound uremic toxins indoxyl sulfate p-cresyl sulfate phenyl sulfate and imidazole propionate are measured in blood urine and feces using LCMSMS

Secondary

MeasureTime frame
eGFR eGFR are assessed at baseline (Visit 2) and at Weeks 12, 16 to 18, and 24 after initiation of activated charcoal (5 g/day) Renal function is assessed by eGFR (mL/min/1.73 m2), residual urine volume by 24-hour urine collection (mL/day), and uremic symptoms by questionnaires.
