Chronic Kidney Disease
Conditions
Brief 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.

Eligibility
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.

Participant flow
Recruitment details
This trial was a Phase II, randomised, placebo-controlled, double-blind (within dose groups), parallel, multicentre clinical trial in patients with non-diabetic kidney disease (non-DKD) to demonstrate the effectiveness and safety of avenciguat and to characterize the dose-response relationship for avenciguat in patients with non-DKD by assessing 3 doses and placebo.
Pre-assignment details
Patients underwent a screening period of up to 3 weeks from the time of informed consent. After confirmation of eligibility at screening, patients continued in a 2-week baseline run-in period. Patients who successfully completed the screening and baseline run-in periods and met the inclusion/exclusion criteria were randomised equally into 1 of 3 parallel dose groups, and in each dose group to treatment either with avenciguat or matching placebo in a 3:1 ratio.

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 random effects of patient. Log transformed UACR at Week 20 was log of (average of all available scheduled measurements between week 18 and week 20). The data in the Outcome Measure Data Table represent the Least Squares Mean (Standard error) at Week 20.
Time frame: 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.
Population: Full Analysis Set (FAS): included all patients who had at least one baseline measurement of UACR in Week -2, -1, or 0 and at least 1 post-baseline measurement after Week 6.
