About
The study aims to determine the short-term efficacy, mechanisms and safety of 12 weeks of dapagliflozin and semaglutide combination therapy in 20 KTR, with and without T2D.
Full description
Kidney transplantation improves survival and quality of life for patients with kidney failure. However, treatment options to protect the heart and the kidney in transplant recipients are lacking. Sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RA) are novel anti-diabetic drugs which not only lower blood sugar, but also lower blood pressure in the kidney's individual filtering units and protect kidney function in the long term. It is unclear if the protective mechanisms of these drugs also occur in people with a kidney transplant. Several smaller studies have shown that SGLT2 inhibitors or GLP-1RA used alone are safe in people with kidney transplants. No studies have yet to look at the combined use of SGLT2 inhibitors and GLP-1RA in kidney transplant recipients (KTR).
The purpose of the HALLMARK study is to determine the mechanisms and safety of the combination use of semaglutide, a GLP-1RA, and dapagliflozin, a SGLT2 inhibitor. To investigate this, 20 kidney transplant recipients with and without diabetes will be treated with both semaglutide or dapagliflozin for 12 weeks followed by a combination of semaglutide and dapagliflozin for 12 weeks. The study will measure salt and water removal as well as the effect on blood pressure, kidney function, heart function, liver stiffness as well as the safety of these agents.
