Objective: This review provides an overview of the pharmacology, efficacy, and safety of sotagliflozin, a dual inhibitor of sodium-glucose cotransporters 1 and 2 (SGLT1 and SGLT2), to reduce the risk of cardiovascular death and hospitalization in those with heart failure. Data sources: A search of Embase via Elsevier, PubMed, Web of Science-All Databases, and The Cochrane Library for clinical trials in CENTRAL, as well as the MedRxiv and BioRxiv pre-print servers, was conducted from inception through December 1, 2023. Search terms included sotagliflozin, lx 4211, lp 802034, sar 439954, and (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol. Study selection and data extraction: Published phase 1, phase 2, and phase 3 clinical trials, meta-analyses, and systematic reviews. Studies were included if they were published in English and evaluated sotagliflozin pharmacology, pharmacokinetics, efficacy, or safety. Data synthesis: The Sotagliflozin in Patients with Diabetes and Recent Worsening Heart Failure (SOLOIST-WHF) and Sotagliflozin on Cardiovascular and Renal Events in Patients with Type 2 Diabetes and Moderate Renal Impairment Who Are at Cardiovascular Risk (SCORED) phase 3 trials compared sotagliflozin with placebo in patients with type 2 diabetes mellitus. In both the SCORED and SOLOIST-WHF trials, treatment with sotagliflozin resulted in a statistically significant reduction in the primary composite outcome of death from cardiovascular causes, hospitalizations due to heart failure (HF), and urgent visits for HF. Conclusions: Dual SGLT1 and SGLT2 inhibition with sotagliflozin is efficacious in reducing myocardial infarction (MI), stroke, and HF hospitalizations and urgent visits in the SCORED and SOLOIST-WHF trials. However, its impact on reducing cardiovascular mortality remains uncertain due to premature study discontinuation. Owing to these factors and lack of generalizability, further studies are needed to establish its role in renal protection and cardiovascular mortality in broader populations. At this time, more evidence is warranted to definitively establish sotagliflozin in HF.
