730 Patients were randomized to receive daily oral aprocitentan or placebo, plus a fixed-dose combination of amlodipine, valsartan, and hydrochlorothiazide.
After 4 weeks, mean change in office systolic BP was 15 mm Hg with aprocitentan and 11 mm Hg with placebo; this 4 mm difference was statistically significant.
What is the cost? What is the long term effects? Why didn't they compare this to the standard of care spironolactone?
