About this trial

This study aims to better understand electrolyte handling in patients with autosomal dominant polycystic kidney disease treated with the SGLT2 inhibitor Empagliflozin.

Patients will be randomized into two groups and take Empagliflozin or a Placebo for 2 weeks with a wash-out period of 2 weeks. The primary outcome is tubular handling of the divalent ions calcium, phosphate and magnesium. Secondary outcomes include diuresis, safety and tolerability.

Trial outcomes

Primary outcomes

1

Primary Outcome

\- Calcium, phosphate, magnesium excretion

Time frame
After a two week intervention

Secondary outcomes

1

Secondary Outcome

\- diuresis (24-hour urine volume, 24-hour creatinine, ketonuria, osmolarity, urinary pH) - tubular handling of other electrolytes (Na, K, Cl) - inflammation metabolism (CRP, hemoglobin?) - kidney function (creatinine, uric acid, urea, hemoglobin?) - effect on standardized blood pressure (assessed every two weeks) - bone metabolism (FGF23, PTH, 25-(OH)-D3) - tolerability (patient-reported side effects (nycturia, urinary urgency, lightheadedness, syncope) - safety (bacteriuria, urinary tract infection requiring antibiotic treatment, genital mycosis)

Time frame
After a two week intervention
