Effect of Avenciguat on Albuminuria in Patients with CKD:… : Journal of the American Society of Nephrology
d trials of identical design. Adults with CKD (eGFR ≥20 and <90 mL/min/1.73 m2, urine albumin-to-creatinine ratio [UACR] ≥200 and <3500 mg/g) were randomized to 20 weeks of placebo or avenciguat 1, 2, or 3 mg three times daily (TID; adjunctive to angiotensin-converting–enzyme inhibitor or angiotensin receptor blocker. Primary endpoint: change from baseline in UACR in 10-hour urine at week 20, analyzed per protocol. Secondary endpoint: UACR change from baseline in first morning void urine at week 20. Safety was monitored throughout. Results: Overall 500 patients (mean age 62 years [SD 13]; mean eGFR 44 mL/min/1.73 m2 [SD 18] and median 10-hour UACR 719 [interquartile range 379–1285] mg/g ) received placebo (n=122) or avenciguat 1 mg (n=125), 2 mg (n=126), or 3 mg (n=127) TID. All 243 patients in study one and 27/261 patients in study two had diabetes. Avenciguat 1, 2, and 3 mg TID reduced UACR in 10-hour and first morning void urine versus placebo throughout the treatment period. At wee
