Brief Summary:

Researchers in this study want to learn more about the safety of the drug runcaciguat and how well it works when given at the highest dose as tolerated by the individual patient whose kidneys are not working properly and suffering at the same time from high blood sugar and/or high blood pressure and a disease of the heart and the blood vessels. Runcaciguat is a new drug under development for the improvement of kidney function. It works by activating proteins that helps to dilate blood vessels, including vessels in the kidneys. This can improve blood flow in kidney and may slow down the progression of kidney disease. This dilative effect can also influence the heart rate and blood pressure. Researchers also wants to find the best dose of the drug during the study.

Participants in this study will receive either runcaciguat or placebo tablets every morning for 8 weeks. A placebo looks like the study drug but does not have any active medicine in it. On a weekly basis, the dose of the runcaciguat will be increased step by step. In total, participants will visit the doctors about 10 times, and the observation will last for about 16 weeks. Blood and urine samples will collected from the participants.

Arm Intervention/treatment
Experimental: runcaciguat
Participant randomized to this arm will be up-titrated. A 30-day safety follow up will be performed after end of treatment or after early discontinuation from the study.
Drug: runcaciguat
Titrated dose of active dose 1, dose 2, dose 3, dose 4 of runcaciguat will be administered orally once a day.

Placebo Comparator: Placebo
Participant randomized to this arm will be sham-titrated. A 30-day safety follow up will be performed after end of treatment or after early discontinuation from the study.
Other: Placebo
Sham-titrated dose of matching placebo will be administered orally once a day.

Primary Outcome Measures :
  1. Mean change in urinary albumin-to-creatinine ratio (UACR) from baseline to the average of multiple time points during treatment [ Time Frame: From baseline up to day 57 (± 3) ]

Secondary Outcome Measures :
  1. Number of subjects with treatment emergent adverse event (TEAE) [ Time Frame: From first treatment administration up to end of follow up (Day 87±7) ]
  2. Number of subjects with early discontinuations [ Time Frame: From first treatment administration up to end of treatment (Day 57±3) ]

  • history of any of the following:

    • type 2 diabetes mellitus as defined by the American Diabetes Association (on treatment with glucose-lowering medications and/or insulin) for at least 2 years, and/or;
    • diagnosis of hypertension (defined as systolic blood pressure [BP] values ≥ 140 mmHg and/or diastolic BP values ≥90 mmHg) and on hypertension medication for at least 5 years;
  • established atherosclerotic cardiovascular disease (e.g. coronary artery disease, peripheral arterial disease, cerebrovascular disease) or heart failure;
  • a clinical diagnosis of chronic kidney disease (CKD) based on all of the following criteria:

    • (estimated) glomerular filtration rate (eGFR) ≥ 25 mL/min/1.73 m^2 but ≤ 60 mL/min/1.73 m^2 (acc. Percentage of decrease in eGFR [CKD EPI]);
    • persistent high albuminuria defined as urine albumin-to-creatinine ratio [UACR] of between 30 mg/g and 3000 mg/g in 2 first morning void samples (collected at least 1 week apart);
    • Stable treatment with angiotensin-converting enzyme inhibitor (ACEi) or angiotensin-receptor blocker (ARB) for the participant maximum tolerated labelled daily dose and otherwise stable antihypertensive treatment both for at least 3 months before randomization, without any adjustments to this therapy for at least 4 weeks prior to randomization;
  • Diabetes patients that are on SGLT2-inhibitor (SGLT: sodium glucose transport protein) have to be on stable treatment for at least 3 months before Screening visit.

Exclusion Criteria:

  • Known non-diabetic and non-hypertension related renal diseases as autosomal dominant polycystic kidney disease, bilateral clinically relevant renal artery stenosis, lupus nephritis, or ANCA-associated vasculitis, IgA nephropathy without hypertension, or any other secondary glomerulonephritis;
  • Clinical diagnoses of heart failure and persistent symptoms (New York Heart Association (NYHA class III - IV);
  • Uncontrolled hypertension indicated by >160 mmHg systolic BP or ≥ 100 mmHg diastolic BP;
  • History of secondary hypertension (i.e., renal artery stenosis, primary aldosteronism, or pheochromocytoma);
  • Stroke, transient ischemic cerebral attack, acute coronary syndrome, or hospitalization for worsening heart failure, in the last 3 months prior to the planned randomization;
