#1418 Phase II dose-selection, randomised, controlled trial of ASi BI 690517 with and without EMPA in CKD: subgroup analysis by T2D status
Abstract
High aldosterone levels accelerate chronic kidney disease (CKD) progression. BI 690517 is a highly selective aldosterone synthase inhibitor (ASi) in clinical development for CKD treatment. ASi may reduce deleterious haemodynamic, inflammatory, and fibrotic actions of aldosterone. Coadministration of BI 690517 with a sodium-glucose cotransporter-2 inhibitor may also mitigate the risk of hyperkalaemia. This multinational, randomised, dose-finding, Phase II trial (NCT05182840) investigated the efficacy and safety of BI 690517, given either alone or in combination with empagliflozin (EMPA), in people who had CKD with or without type 2 diabetes (T2D) [1, 2]. Here, we present an analysis by T2D status (pooled for background randomizedon to EMPA or placebo [PBOEMPA]).
Adults with CKD receiving a maximally tolerated dose of a renin-angiotensin system inhibitor were randomized (R1) 1:1 to an 8-week run-in to receive background EMPA 10 mg or PBOEMPA, then randomized again (R2) 1:1:1:1 to receive BI 690517 (3 mg, 10 mg, or 20 mg) or PBOASI for 14 weeks. The primary endpoint was the change from R2 baseline in urine albumin:creatinine ratio (UACR) in the first morning void of urine at Week 14. A secondary endpoint was UACR response (≥30% reduction from R2 baseline in UACR at Week 14). Changes in systolic blood pressure (SBP) and estimated glomerular filtration rate (eGFR) from R2 baseline to Week 14 were also assessed, as were safety outcomes.
Of 586 people randomized at R2, 414 (70.6%)…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 586 participants or records.
