Baxdrostat for High Blood Pressure (BaxHTN Trial)
Phase 3
Recruiting
Research Sponsored by AstraZeneca
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Male or female participants must be ≥ 18 years old
- uHTN subpopulation: have a stable regimen of 2 antihypertensive medications, from different therapeutic classes (at least one should be a diuretic), at maximum tolerated dose in the judgement of the Investigator

Follow Up up to week 54
Awards & highlights
Pivotal Trial
Summary
This trial tests Baxdrostat, a pill taken regularly, in adults with high blood pressure that isn't controlled by their current medications. Baxdrostat works by lowering the force of blood against artery walls.
Who is the study for?
This trial is for adults with high blood pressure not controlled by at least two medications, including a diuretic. Participants must have certain levels of potassium and kidney function. It's not for those with extremely high blood pressure or secondary causes like thyroid issues or specific heart conditions.
What is being tested?
The study tests Baxdrostat (1 or 2 mg daily) against a placebo in reducing systolic blood pressure. It's a Phase III trial where participants are randomly assigned to either the drug or placebo group without knowing which one they're receiving.
What are the potential side effects?
While the side effects aren't listed here, typical ones may include dizziness, headache, fatigue, and potential electrolyte imbalances due to its effect on blood pressure and kidney function.

Other Research
Common treatments for high blood pressure include diuretics, which help the kidneys remove excess sodium and water, reducing blood volume; ACE inhibitors and ARBs, which relax blood vessels by inhibiting the renin-angiotensin-aldosterone system; beta-blockers, which reduce heart rate and the force of contraction; and calcium channel blockers, which relax blood vessel walls. Aldosterone antagonists, like spironolactone, block the effects of aldosterone, reducing sodium retention and blood pressure.
Baxdrostat, an aldosterone synthase inhibitor, works by directly inhibiting the production of aldosterone, offering a targeted approach to reduce blood pressure. These mechanisms are crucial for managing high blood pressure, as they address different pathways that contribute to elevated blood pressure, providing comprehensive control and reducing the risk of cardiovascular events.
