a study to learn how safe the study drug finerenone is and how well it works in indian people with long-term decrease in the kidneys' ability to work properly (chronic kidney disease) together with type 2 diabetes mellitus

Conditions: Chronic Kidney Disease; Type 2 Diabetes Mellitus

Summary: researchers are looking for a better way to treat people with chronic kidney disease (ckd), a progressive decrease in the kidneys' ability to work properly, and type 2 diabetes (t2d). in people with t2d, the body does not make enough of a hormone called insulin or does not use the insulin well enough. insulin's role is to regulate the amount of glucose (sugar) in the blood. too much blood sugar can cause damage to the kidneys over time. consequently, ckd can happen as one of the complications of t2d. the study treatment finerenone works by blocking a group of proteins, called mineralocorticoid receptor. an increased stimulation of the mineralocorticoid receptor is known to trigger injury and inflammation in the kidney and is therefore thought to play a role in ckd. finerenone is already available in several countries for doctors to prescribe to people with ckd and t2d. in addition, it was recently approved in india with a request to specifically gather information on finerenone therapy in indians. the main purpose of this study is to learn how safe finerenone is in indian people with ckd and t2d. for this, the researchers will count the number of participants who have: * medical problems after taking finerenone * abnormal high levels of potassium in the blood (called hyperkalemia). researcher will also count the number of participants in whom hyperkalemia: * leads to stop of finerenone treatment * requires treatment to filter wastes and water from the blood * leads to a hospital stay. doctors keep track of all medical problems that happen in studies, even if they do not think the medical problems might be related to the study treatments. in addition, the study team will collect more data about how well finerenone works in indian people with ckd and t2d under real world setting. working well means that the treatment can prevent the following from happening: * reduced kidney function over a period of at least 4 weeks * death from renal problems * death due to conditions affecting the heart and blood circulation * heart attack (blocked blood flow to the heart) * hospital stay due to a condition which occurs when the heart does not pump blood as well as it should * changes of the albumin and creatinine levels in urine. the participants will be in the study for approximately 20 months. they will take the study treatment once daily as a tablet by mouth for 18 months. in the study, 9 visits to the study site are planned. during the study, the study team will: * take blood and urine samples * do physical examinations * check the participants' overall health * do pregnancy tests * examine heart health using electrocardiogram ecg * check vital signs. about 30 days after the participants take their last treatment, the study doctors and their team will check worsening of reported underlying diseases: * damage to the blood vessels in the tissue of the retina at the back of the eye, as a result of diabetes mellitus * a long-term condition where the heart does not pump blood as well as it should with symptoms such as shortness of breath, tiredness and ankle swelling * heart attack (blocked blood flow to the heart) * death due to conditions affecting the heart and blood circulation or * hospital stay.


Eligibility criteria:
inclusion criteria: * participants capable of giving signed informed consent signed before any study-specific procedure and willing to comply with the study-related procedures. * diagnosis of chronic kidney disease (ckd) associated with type 2 diabetes (t2d). * participants who are drug naïve for finerenone or patients who have been initiated on finerenone therapy within 4 weeks before signing the informed consent. * participants with serum potassium level ≤ 4.8 mmol/l at the time of screening. if serum potassium level \> 4.8 to 5.0 mmol/l, participants may be enrolled in the study, but additional potassium samples may be required; the potassium level needs to be confirmed during screening. participants with potassium level \> 5.0 mmol/l are not allowed. the sample for potassium assessment for confirming eligibility shall be available before initiation of treatment with finerenone. * contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. exclusion criteria: * contraindications according to the local marketing authorization: 1. participants with egfr \< 25 ml/min/1.73 m\^2 (calculated based on the ckd-epi equation, using 2009 formula). egfr can be reassessed once within 48 hours. 2. participants with severe hepatic impairment (child-pugh c). 3. participants with known hypersensitivity to the study treatment (active substance or excipients). 4. participants with type 1 diabetes. 5. participants taking concomitant medications that are strong cyp3a4 inhibitors. 6. participants with addison's disease. * glycated hemoglobin \> 12% (17.5 mmol/l) at the screening visit. * participants treated with another mineralocorticoid receptor antagonist (mra), a renin inhibitor, potassium supplements, a potassium sparing diuretic, a potassium binder agent, or angiotensin receptor neprilysin inhibitor (arni) within 8 weeks prior to the screening visit and during finerenone treatment. * participation in another interventional clinical trial within 30 days prior to the screening visit and during finerenone treatment. * female participants who are pregnant or breast-feeding or plan to become pregnant or to breastfeed during the course of the study. * participants known for lack of compliance with clinic visits or prescribed medication.
