Relative Efficacy of Sacubitril-Valsartan, Vericiguat, and SGLT2 Inhibitors in Heart Failure with Reduced Ejection Fraction: a Systematic Review and Network Meta-Analysis

Background: Sacubitril/valsartan, vericiguat, and the sodium-glucose co-transporter-2 inhibitors (SGLT2i) dapagliflozin and empagliflozin proved effective in phase 3 trials on heart failure with reduced ejection fraction (HFrEF). Methods: We compared the treatment arms (sacubitril/valsartan, vericiguat, and SGLT2i) with the respective control arms (standard-of-care [SOC]) through a network meta-analysis of the phase 3 trials (PARADIGM-HF, VICTORIA, DAPA-HF, EMPEROR-Reduced), a phase 2 trial on vericiguat and the HFrEF subgroup of DECLARE-TIMI 58. Results: There was a trend towards decreased risk of cardiovascular (CV) death or HF hospitalization with SGLT2i than sacubitril/valsartan (HR 0.92, 95% CI 0.81 to 1.05) and vericiguat (HR 0.83, 95% CI 0.73 to 0.94). A non-significant effect of SGLT2i on CV mortality compared to sacubitril/valsartan (HR 1.04, 95% CI 0.88 to 1.24) and vericiguat (HR 0.88, 95% CI 0.63 to 1.22) was found. SGLT2i demonstrated the greatest effect on HF hospitalization (HR 0.69, 95% CI 0.62 to 0.77) over the SOC, as well as a significant benefit over vericiguat (HR 0.77, 95% CI 0.66 to 0.89), but not over sacubitril/valsartan (HR 0.87, 95% CI 0.75 to 1.02). SGLT2i were ranked as the most effective therapy, followed by sacubitril/valsartan and vericiguat. Conclusions: Based on an indirect comparison, SGLT2i therapy is not associated with a significantly lower risk of CV death or HF hospitalization or CV death alone compared to sacubitril/valsartan or vericiguat. The risk of HF hospitalization does not differ significantly between patients on SGLT2i or sacubitril/valsartan, while dapagliflozin is superior to vericiguat. Registration Number: PROSPERO ID 186351.
