ClinConnect Summary

The ZENITH High Proteinuria study is looking at two treatments for people with chronic kidney disease (CKD) who have high levels of protein in their urine, a condition known as high proteinuria. Specifically, the trial will compare the effects of a combination medication called zibotentan/dapagliflozin to dapagliflozin alone. This research aims to find out which treatment is more effective and to assess their safety and how well patients tolerate them.

To participate, you need to be 18 years or older with a diagnosis of CKD that meets certain criteria. You should also be stable on specific heart medications for at least four weeks. If you join the study, you will receive either of the treatments and be monitored closely for any side effects or changes in your condition. It's important to note that certain health issues or recent hospitalizations may exclude you from participating, so it's best to discuss with your doctor if you're interested. This trial is actively recruiting participants, and your involvement could help improve treatment options for CKD in the future.

  • Exclusion Criteria:
  • 1. Participants with NYHA class III or class IV Congestive HF at the time of enrolment.
  • 2. Participants hospitalised for HF during the last 6 month prior to screening.
  • 3. Evidence of rales or jugular venous distention on physical examination.
  • 4. Participants with type 1 diabetes mellitus.

  • 6. Blood pressure above 160 mmHg systolic.
  • 7. Blood pressure below 90 mmHg systolic.
  • 8. Participants hospitalised for heart disease or cardiac procedures or for COVID-19 during the last 3 months prior to screening.
  • 9. History of solid organ transplantation or bone marrow transplant.
  • 10. History or ongoing allergy/hypersensitivity, as judged by the Investigator, to SGLT2i therapy (eg, dapagliflozin, canagliflozin, empagliflozin or other SGLT2 inhibitors) or Endothelin Receptor Antagonists (eg, ambrisentan, atrasentan, bosentan, or other).
  • 11. Any condition with a life expectancy of less than 2 years based on investigator´s clinical judgment.
