New study reveals how diabetes drug semaglutide may protect kidneys
NCT ID NCT04865770
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how semaglutide, a diabetes medicine, affects the kidneys in people with type 2 diabetes and chronic kidney disease. 106 participants received either semaglutide or a placebo injection once a week for about a year. Researchers used MRI scans, blood and urine tests, and kidney biopsies to measure changes in kidney oxygen, blood flow, and inflammation.

Inclusion Criteria: * Male or female. * Age above or equal to 18 years at the time of signing informed consent. * Diagnosed with T2D (type 2 diabetes) greater than or equal to 180 days prior to the day of screening. * HbA1c (glycated haemoglobin) below or equal to 9.0 percent (below or equal to 75 mmol/mol). * Depending on biopsy/non-biopsy population: 1. For subjects in the non-biopsy population: Serum creatinine-based eGFR greater than or equal to 30 and below or equal to 75 mL/min/1.73 m\^2(CKD-EPI). 2. For subjects in the biopsy sub-population: Serum creatinine-based eGFR greater than or equal to 40 and below or equal to 75 mL/min/1.73 m\^2(CKD-EPI). * UACR ( Urinary albumin-to-creatinine ratio ) greater than or equal to 20 and below 5000 mg/g. * Treatment with maximum labelled or tolerated dose of a renin-angiotensin-aldosterone system (RAAS) blocking agent including an angiotensin converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB)) unless such treatment is contraindicated or not tolerated.Treatment dose must be stable for at least 28 days prior to screening. Exclusion Criteria: * Use of any glucagon-like peptide 1 receptor agonist (GLP-1 RA) within 30 days prior to screening. * A prior solid organ transplant or awaiting solid organ transplant. * Myocardial infarction, stroke, hospitalisation for unstable angina pectoris or transient ischaemic attack within 180 days prior to the day of screening. * Presence or history of malignant neoplasms (other than basal or squamous cell skin cancer, in situ carcinomas of the cervix, or in situ prostate cancer) within 5 years prior to the day of screening. * Congenital or hereditary kidney diseases including polycystic kidney disease, autoimmune kidney diseases including glomerulonephritis or congenital urinary tract malformations. * Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a fundus examination performed within the past 90 days prior to screening or in the period between screening and Visit 2. Pharmacological pupil-dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination. * Treatment with systemic anti-inflammatory or immunosuppressant drugs within 90 days prior to screening. Stable treatment with acetylsalicylic acid for prevention of cardiovascular events and occasional use of propionic acid derivatives drugs (e.g. ibuprofen) is allowed. * Any contraindication for MRI according to standard checklist used in clinical routine, including claustrophobia or metallic foreign bodies, metallic implants, internal electrical devices, or permanent makeup/tattoos that cannot be declared MR compatible. * Combination use of an ACE (angiotensin-converting enzyme) inhibitor and an ARB (angiotensin II receptor blockers).
