A Study to Test the Effect of Different Doses of Avenciguat (BI 685509) on Kidney Function in People With Chronic Kidney Disease

Plain-language 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Signed and dated written informed consent in accordance with International Council on Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial.
* Male or female patients aged ≥18 years at time of consent.
* Estimated glomerular filtration rate (eGFR) (Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\] formula) ≥ 20 and \< 90 mL/min/1.73 m2 at Visit 1 by central laboratory analysis. eGFR must remain ≥20 mL/min/1.73 m2 after Visit 1 up to the start of Visit 3, measured by central or any local laboratory analysis.
* Urine albumin creatinine ratio (UACR) ≥ 200 and \< 3,500 mg/g in spot urine (midstream urine sample) by central laboratory analysis at Visit 1.
* Patients with macroalbuminuria (\>300 mg/g) should be treated with the highest tolerated dose of either Angiotensin Converting Enzyme inhibitor (ACEi) or Angiotensin Receptor Blocker (ARB) (but not both). For patients with microalbuminuria the use of ACEi or ARB is at the discretion of the Investigator. Treatment should be at a stable dose for ≥ 4 weeks before Visit 1 with no planned change of the therapy during the trial.
* If the patient is taking any of the following medications they should be on a stable dose at least 4 weeks prior to visit 1 until start of treatment, with no planned change of the therapy during the trial: anti-hypertensives, non-steroidal anti-inflammatory drugs (NSAIDs), endothelin receptor antagonists, systemic steroids or …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Change From Baseline in Log Transformed Urine Albumin Creatinine Ratio (UACR) Measured in 10-hour Urine After 20 Weeks of Trial Treatment
Timeframe: The MMRM model is a longitudinal analysis and it incorporated UACR measurements from baseline (Week -2, Week -1, Week 0 pre-dose) and Week 6, Week 12 and Week 20. The data represent the Least Squares Mean at Week 20.
