An observational study in Type 2 Diabetes Mellitus and Diabetic Kidney Disease, sponsored by First Affiliated Hospital of Chongqing Medical University. Not yet recruiting. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-07-21.

This is a single-center prospective observational clinical study conducted at the First Affiliated Hospital of Chongqing Medical University. A total of 425 patients aged 18-75 years with type 2 diabetes mellitus-related chronic kidney disease will be enrolled from February 2026 to January 2029. All participants will receive standard finerenone treatment in accordance with clinical guidelines with a 4-month follow-up period. Blood and urine samples will be collected at screening, baseline, 1 month, 2 months and 4 months after treatment initiation for routine biochemistry, aldosterone/renin testing, captopril suppression test and multi-omics analysis.
Participants will be categorized into benefit group, partial benefit group and non-benefit group based on the reduction rate of urine albumin-to-creatinine ratio (UACR) at Month 4. We will combine demographic data, laboratory indicators and multi-omics profiles to identify key biomarkers predicting finerenone response, and construct a predictive model to realize precise individualized therapy for diabetic kidney disease.
All study-related laboratory tests are free of charge for subjects. A priority consultation channel is available during follow-up, and free professional consultation on diabetic nephropathy will be provided. Serum potassium and renal function will be closely monitored to manage safety risks such as hyperkalemia. All personal data and biological samples are anonymized and stored in encrypted systems with strict confidentiality protection. Subjects may withdraw from the study voluntarily at any time without interference to their routine clinical care.
This single-center prospective observational cohort study will recruit 425 eligible adult patients aged 18-75 years diagnosed with type 2 diabetes mellitus associated chronic kidney disease (T2DM-CKD) from the Chongqing Diabetes Registry, endocrine wards and outpatient clinics of the First Affiliated Hospital of Chongqing Medical University between February 2026 and January 2029. All enrolled subjects will receive guideline-directed finerenone oral therapy for a 4-month observation period, with dose adjusted based on baseline eGFR and serum potassium levels per drug instructions.
Serial blood and urine biospecimens will be collected at screening, baseline, month 1, month 2 and month 4 visits. Collected samples will be tested for routine biochemistry, electrolytes, renal function, HbA1c, plasma renin and aldosterone; captopril suppression test and multi-omics profiling will also be performed at designated time points.
According to the percentage reduction of urine albumin-to-creatinine ratio (UACR) at month 4, participants will be stratified into three subgroups: benefit group (UACR reduction ≥30%), partial benefit group (10% ≤ UACR reduction \<30%), and non-benefit group (UACR reduction \<10% or elevated UACR). Primary objective is to identify core biomarkers associated with finerenone therapeutic response. Secondary outcomes include serial changes in eGFR, UACR, serum potassium, aldosterone and renin across all follow-up time points.
Sample size calculation was performed using R pmsampsize package, accounting for a 10% anticipated loss to follow-up to reach the target sample of 425 subjects. All statistical analyses will be conducted via R and Python with machine learning algorithms to develop and validate a predictive model for finerenone efficacy.
Safety monitoring including serum potassium and renal function assessment will be conducted at every visit. Subjects with hyperkalemia or progressive renal impairment will suspend finerenone per predefined criteria. All study-related laboratory examinations are provided free of charge to participants, with priority medical consultation service available throughout follow-up. All personal clinical data and biological samples are anonymized and stored under encrypted management to protect participant privacy. Subjects may withdraw consent at any time without impact on routine clinical treatment. Study findings will be summarized and published in peer-reviewed journals after data collection is fully completed.

This is a prospective observational cohort study enrolling patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD) receiving finerenone therapy. Subjects will be recruited from the Chongqing Diabetes Registry (CDR), endocrine outpatient and inpatient departments of the First Affiliated Hospital of Chongqing Medical University, with a recruitment window from February 2026 to January 2029. A total of 425 eligible participants are planned to be enrolled.
A target sample size of 425 participants is determined using the R pmsampsize package for predictive model development. Key input parameters: C-statistic of 0.80, 10 candidate predictive variables, expected finerenone responder proportion of 53.2% derived from FIDELIO-DKD and FIGARO-DKD trials. The minimum required sample size to satisfy model stability and calibration criteria is 383 participants. A 10% attrition rate is accounted for, leading to the final enrolment target of 425 patients.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

All enrolled participants with type 2 diabetes mellitus-related chronic kidney disease receive guideline-standard oral finerenone therapy for a 4-month observation period. The finerenone dose is adjusted according to each subject's baseline eGFR and serum potassium level following the official drug instructions. Concomitant hypoglycemic, antihypertensive and lipid-lowering medications remain stable during the whole study period as required by inclusion criteria. Serial blood and urine biospecimens are collected at multiple follow-up time points for routine biochemical tests, captopril suppression test and multi-omics detection. After 4 months of treatment, subjects will be divided into three analytic subgroups based on UACR reduction rate to explore predictive biomarkers of finerenone efficacy.
Drug: Finerenone
Oral finerenone administered once daily for 4 months. Dosage is individualized based on baseline estimated glomerular filtration rate (eGFR) and serum potassium per drug labeling. Subjects maintain stable background hypoglycemic, antihypertensive and lipid-lowering therapies throughout the observational period. No additional study-specific drugs or experimental procedures are applied; only routine clinical finerenone treatment is observed with serial blood and urine sample collection for multi-omics and biomarker analysis.
