Study Summary

This study is open to adults who have kidney disease that is not caused by diabetes. The purpose of the study is to find out whether a medicine called avenciguat (BI 685509) improves kidney function. Three different doses of avenciguat are tested in this study. Participants get either one of the three doses of avenciguat or placebo. It is decided by chance who gets which avenciguat dose and who gets placebo. Participants take avenciguat or placebo as tablets 3 times a day. Placebo tablets look like avenciguat tablets but do not contain any medicine. Participants continue taking their usual medicine for kidney disease throughout the study. Participants are in the study for about 7 months. During this time, they visit the study site about 11 times. Where possible, about 6 of the 11 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Kidney function is assessed based on the analysis of urine samples, which participants collect at home. At the end of the trial the results are compared between the different doses of avenciguat and placebo. During the study, the doctors also regularly check the general health of the participants.

Primary Outcome

Change from baseline in log transformed Urine Albumin Creatinine Ratio (UACR) measured in 10-hour urine after 20 weeks of trial treatment is reported. Least Squares Mean (Standard error) were estimated by restricted maximum likelihood (REML)-based mixed-effect model for repeated measures (MMRM) including the fixed, categorical effects of treatment at each visit (baseline, Week 6, Week 12, and Week 20), and the continuous effect of baseline at each visit (Week 6, Week 12, and Week 20) as well as
