Efficacy and safety of sacubitril/allisartan for the treatment of primary hypertension: a phase 2 randomized, double-blind study


This randomized, double-blind phase 2 study assessed the efficacy and safety of sacubitril/allisartan, an angiotensin receptor neprilysin inhibitor, compared with placebo in Chinese patients with mild to moderate hypertension. Eligible patients aged 18–75 years (n = 235) with mild to moderate hypertension were randomized to receive sacubitril/allisartan 120 mg (n = 52), sacubitril/allisartan 240 mg (n = 52), sacubitril/allisartan 480 mg (n = 52), placebo (n = 26) or olmesartan 20 mg (n = 53) once daily for 8 weeks. The primary end point was a reduction in clinic systolic blood pressure from baseline with different doses of sacubitril/allisartan versus placebo at 8 weeks. Secondary efficacy variables included clinic diastolic blood pressure and 24-h ambulatory blood pressure for the comparison between sacubitril/allisartan and placebo at 8 weeks. Safety assessments included all adverse events and serious adverse events. Sacubitril/allisartan 480 mg/day provided a significantly greater reduction in clinic systolic blood pressure than placebo at 8 weeks (between-treatment difference: −9.1 mmHg [95% confidence interval −1.6 to −16.6 mmHg], P = 0.02). There were also significant reductions in 24-h, daytime and nighttime systolic and diastolic blood pressure for sacubitril/allisartan 480 mg/day compared with placebo (P ≤ 0.03). Similarly, a greater reduction in daytime systolic blood pressure was observed for sacubitril/allisartan 240 mg/day compared with placebo (between-treatment difference: −7.3 mmHg [95% confidence interval −0.5 to −14.0 mmHg], P = 0.04). Sacubitril/allisartan was well tolerated, and no cases of angioedema were reported. Sacubitril/allisartan is effective for the treatment of hypertension in Chinese patients and is well tolerated.
