In type 2 diabetes patients, the study did not indicate different clinical impacts of dual and single SGLT inhibition.
Germany: Inhibition of sodium-glucose cotransporters (SGLTs) improves cardiovascular and glycemic outcomes in type 2 diabetes (T2D) patients. Niklas Walther, Charité Research Organisation GmbH, Berlin, Germany, and colleagues investigated the differential impact of selective SGLT2 inhibition (empagliflozin) and dual SGLT1 and SGLT2 inhibition (sotagliflozin) on multiple parameters.
Based on their study, published in Diabetes Care, the research team did not find any significant differences between sotagliflozin and empagliflozin concerning overall BP and glycemic control or selected urinary, metabolic, and intestinal parameters.
SGLT2 inhibition is an established approach for blood sugar control in type 2 diabetes patients. It also reduces heart failure and major cardiovascular adverse events in patients irrespective of their diabetic status. SGLT2 is majorly expressed in the kidney, where its inhibition results in marked natriuresis and glycosuria, whereas SGLT1 is mainly present in the gastrointestinal tract, where it can exhibit the main effect of glucose inhibition.
SGLT1 and SGLT2 dual inhibition could offer additional advantages, at least for lowering blood glucose, yet the knowledge of the extent of any other pharmacodynamic effects remains incomplete. Sotagliflozin is a dual l SGLT1 and SGLT2 inhibitor approved in the European Union as an adjunct therapy to insulin in type 1 diabetes patients with a BMI ≥27 kg/m2.
The study included 40 patients with T2D and hypertension. Using a double-blind, parallel-group design, they were randomized to receive the selective SGLT2 inhibitor empagliflozin 25 mg or the dual SGLT1 and SGLT2 inhibitor sotagliflozin 400 mg, with preexisting antihypertensive treatment, for eight weeks. In an in-house testing test, many clinical and laboratory tests were used to determine intestinal, metabolic, urinary, and cardiovascular parameters over 24h.
The study led to the following findings:
“Changes from baseline in blood pressure and glycemic control, cardiovascular biomarkers, and other parameters were similar between sotagliflozin and empagliflozin,” the researchers wrote in their study. “However, sotagliflozin inhibited intestinal SGLT1 after breakfast as shown by larger changes in insulin, GIP, postprandial glucose, and GLP-1 AUCs, especially after breakfast.”
