Combining ERAs with sodium-glucose cotransporter 2 (SGLT2) inhibitors, which have diuretic effects, offers a promising strategy to mitigate fluid retention. In this post-hoc analysis of the ZENITH-CKD trial, we assessed fluid dynamics in patients with CKD treated with the ERA zibotentan alone, and in combination with the SGLT2 inhibitor dapagliflozin.</p><p><strong>Methods: </strong>In ZENITH-CKD, 508 patients with CKD (estimated glomerular filtration rate ≥ 20 mL/min/1.73m2 and a urinary albumin-to-creatinine ratio of 150-5000 mg/g) were randomized to treatment with placebo, dapagliflozin 10 mg plus placebo, zibotentan (0.25, 1.5 or 5 mg) plus dapagliflozin 10 mg and zibotentan 5 mg plus placebo. We evaluated correlations between changes in fluid retention markers and bioimpedance-measured extracellular fluid (ECF) in response to zibotentan treatment.

Higher doses of zibotentan were associated with significantly higher risk of fluid retention compared to dapagliflozin alone (zibotentan 5 mg HR 8.50 (95%CI 3.40, 21.30).
