NCT06435858 | RECRUITING | Autosomal Dominant Polycystic Kidney Disease

Short-term Effects of an SGLT2 Inhibitor on Divalent Ions in Autosomal Dominant Polycystic Kidney Disease
Sponsor:

Cantonal Hospital Graubuenden

Information provided by (Responsible Party):

Patrick Hofmann

Brief Summary:

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.

Condition or disease

Autosomal Dominant Polycystic Kidney Disease

Intervention/treatment

Empagliflozin

Placebo

Phase

PHASE4

Detailed Description:

This investigator-initiated randomised, single-blind, placebo-controlled cross-over study aims to better understand tubular electrolyte handling of divalent ions in patients with autosomal dominant polycystic kidney disease treated with the SGLT2 inhibitor Empagliflozin. After randomization, at week 0, participants collect 24-hour urine sample and a patient visit to assess vitals and blood tests takes place. After this visit, period 1 starts with a 2-week treatment of either Empagliflozin 10mg or Placebo. At week 2, the second 24-hour-urine sample and 2. patient visit and blood test take place. After this visit, wash-out period for 2 weeks starts where no study drug will be administered At week 4, the period 2, the crossover-period starts for an additional 2 weeks. At week 6; a final and third 24-hour urine sample, clinical visit and blood test takes place. At week 3 \& 7, a phone consultation will assess safety.
