Aldosterone Synthase Inhibition With Lorundrostat for Uncontrolled Hypertension

JAMAPublished

  • Randomised controlled trial
  • placebo-controlled
  • dose-ranging

Randomised July 2021–June 2022; final follow-up September 2022

Authors' conclusion

Among individuals with uncontrolled hypertension, use of lorundrostat was effective at lowering blood pressure compared with placebo, which will require further confirmatory studies.

Study context

Population
Adults with uncontrolled hypertension taking ≥2 antihypertensive medications; initial cohort with suppressed plasma renin (PRA ≤1.0 ng/mL/h) and elevated plasma aldosterone (≥1.0 ng/dL), second cohort with PRA >1.0 ng/mL/h163 suppressed PRA + 37 not
Participants
200 adults
Comparison
Lorundrostat vs placebo
Primary endpoint
Change in automated office SBP from baseline
Follow-up
Week 8
