Sumario:BACKGROUND AND OBJECTIVE: Vericiguat is approved for the treatment of patients with heart failure with ejection fraction < 45%. Sildenafil, indicated for the treatment of erectile dysfunction, is a potential co-medication in male patients. This study investigated the safety and tolerability of co-administration of vericiguat and sildenafil in healthy volunteers. METHODS: This was a single-center, randomized, placebo-controlled, parallel-group study in 32 healthy white male volunteers. Participants received vericiguat 10 mg or placebo once daily for 16 days. Both groups received single doses of sildenafil (25 mg, 50 mg, and 100 mg) on days 13–15. Safety, hemodynamic changes, and pharmacokinetic effects were assessed. RESULTS: All subjects in the vericiguat group and seven (43.8%) in the placebo group reported one or more treatment-emergent adverse events, all of mild or moderate intensity. Decreases in seated blood pressure (≤ 5.4 mmHg) with the vericiguat-sildenafil combination compared with placebo-sildenafil were small and there was no evidence of a sildenafil dose-related effect. Standing blood pressure and standing and seated heart rate were similar between treatment groups. Co-administration of sildenafil did not affect vericiguat pharmacokinetics. A mild increase in sildenafil exposure (≤ 22%) when co-administered with vericiguat was observed. CONCLUSIONS: Adding single doses of sildenafil to vericiguat 10 mg once daily at steady state was well tolerated and produced a minimal reduction in seated blood pressure (≤ 5.4 mmHg) compared with administration of sildenafil alone. There was no effect of sildenafil on vericiguat pharmacokinetics, and an increase in sildenafil exposure with vericiguat co-administration was not clinically relevant.
