Researchers are looking for a better way to treat people who have non-diabetic chronic kidney disease (non-diabetic CKD). The trial treatment, finerenone, is being developed to help people who have long lasting kidney disease, also known as chronic kidney disease (CKD). It works by blocking a certain hormone called aldosterone that causes injury and inflammation in the heart and kidney which is known to play a role in CKD.

In this trial, the researchers want to learn if finerenone helps to slow down the worsening of the participants' non-diabetic CKD compared to a placebo. A placebo looks like a trial treatment but does not have any medicine in it. The trial will include about 1,580 men and women who are at least 18 years old.

The participants will take finerenone or a placebo once a day as tablets by mouth. All of the participants will also continue to take their current medicine for their CKD. The participants will be in the trial for up to about 50 months.

During the trial, the doctors will collect blood and urine samples and check the participants' health. The participants will also answer questions about how they are feeling and what adverse events they are having. An adverse event is a medical problem that happens during the trial. Doctors keep track of all adverse events that happen in trials, even if they do not think the adverse events might be related to the trial treatments.

Inclusion Criteria:

• A clinical diagnosis of chronic kidney disease and:

  • Urine albumin/creatinine ratio (UACR) of ≥ 200 but ≤ 3500 mg/g and estimated glomerular filtration rate (eGFR) ≥ 25 but < 90 mL/min/1.73m^2 at screening, and
  • Documentation of albuminuria/proteinuria in the participant's medical records at least 3 months prior to screening.

• Stable and maximum tolerated labeled dose of an Angiotensin-converting enzyme inhibitor (ACEI) or Angiotensin receptor blocker (ARB) for at least 4 weeks prior to screening

• K+ ≤ 4.8 mmol/L at screening

Exclusion Criteria:

• Established diagnosis of Type 1 or 2 Diabetes mellitus, or HbA1c ≥ 6.5% (48 mmol/mol)
• Autosomal dominant or autosomal recessive polycystic kidney disease
• Lupus nephritis or anti-neutrophilic cytoplasmic autoantibody (ANCA) -associated vasculitis or any other primary or secondary kidney disease requiring immunosuppressive therapy within 6 months prior to screening
• Symptomatic heart failure with reduced ejection fraction with class 1A indication for Mineralocorticoid receptor antagonists (MRAs)

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014. Interested researchers can use www.clinicalstudydatarequest.com to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research.
