Zibotentan and Dapagliflozin in Patients With Type 2 Diabetes and Elevated Albuminuria
Zibotentan and Dapagliflozin in Patients With Type 2 Diabetes and Elevated Albuminuria

NCT05570305

CompletedPhase 2

Sponsor: University Medical Center Groningen

Conditions: Chronic Kidney Diseases

Interventions: Zibotentan, Dapagliflozin, Placebo, Dapagliflozin and Zibotentan

Countries: United States, Canada, Denmark, Netherlands, United Kingdom

The aim of this study is to test the hypothesis that the effects on albuminuria of combination treatment with the endothelin receptor antagonist zibotentan and SGLT2i dapagliflozin are complimentary and additive while the fluid retaining effects of zibotentan can be mitigated by dapagliflozin.

  * Evidence of urinary obstruction or difficulty in voiding at screening
* Severe hepatic impairment
* History of epilepsy syndrome
* History of severe hypersensitivity or contraindications to dapagliflozin
