Sotagliflozin vs Dapagliflozin: A Systematic Review Comparing Cardiovascular Mortality.

After the debut of the results of the effect of Sotagliflozin on Cardiovascular Events in Patients with Type 2 Diabetes Post Worsening Heart Failure (SOLOIST-WHF) and Sotagliflozin in Patients With Chronic Kidney Disease and Type 2 Diabetes (SCORED) trials at the American Heart Association's 2020 Scientific session, sotagliflozin became the first drug and the third sodium glucose co-transporter-2 (SGLT-2) inhibitor to be approved for heart failure (HF) across the spectrum of ejection fraction (EF). In light of this recent major U.S. Food and Drug Administration (FDA) approval of sotagliflozin, we conducted a systematic review to compare the cardiovascular mortality rates between sotagliflozin and dapagliflozin in patients with HF. To find relevant articles, we extensively searched major research literature databases and search engines such as PubMed, MEDLINE, PubMed Central, Google Scholar, Embase, and Cochrane Library. We compared the results of significant trials involving sotagliflozin with the trials studying dapagliflozin to provide comprehensive mortality results of both drugs. The results showed that the timely initiation of sotagliflozin in HF cases significantly reduces cardiovascular mortality, hospitalizations, and urgent HF visits. Comparative trials with dapagliflozin indicate enhanced mortality reduction associated with greater initial symptom burden. The results of these major trials cannot be overlooked due to the large size of the combined trials, the randomized design, and the high standards with which they were conducted. The pathophysiology behind the cardioprotection offered by these agents is complex and multifactorial, but it is believed that due to the diuretic-like function, SGLT-2 inhibitors reduce glycemic-related toxicity, promote ketogenesis, and exert antihypertrophic, antifibrotic, and anti-remodeling properties. The benefits of dapagliflozin on cardiovascular death and worsening HF in patients with mildly reduced or preserved EF appeared especially pronounced in those with a greater degree of symptomatic impairment at baseline. Sotagliflozin led to a rise in the count of days patients were alive and not hospitalized (DAOH), which offers an extra patient-centered measure to assess the impact of the disease burden. The data in our article will help future researchers conduct large-scale trials with sotagliflozin to identify and implement it in the treatment of patients with HF as a mortality-reducing drug and to improve the quality of life for patients with HF.
