This study tests a new pill called vicadrostat taken with another medicine (empagliflozin) to see if it helps people with type 2 diabetes, high blood pressure, and heart disease. It may reduce the risk of heart problems, but you must not have had heart failure or use certain other heart medications.
Beverly Hills, CaliforniaAges 18 years+ - NCT07288398RecruitingPhase 3
Levosimendan for exercise limitation in PH-HFpEF
This trial tests if the drug levosimendan can help people with a specific type of pulmonary hypertension (PH-HFpEF) feel less tired and breathless during daily activities, and improve their exercise ability.
Sacramento, CaliforniaAges 18–85 - NCT06297291Recruiting
Long-term safety study for a kidney nerve treatment
This study tests a device that uses ultrasound to calm overactive kidney nerves, which may help lower blood pressure. It is for people with high blood pressure that is hard to control with medication.
Long Beach, CaliforniaAges 18 years+ - NCT06402968Recruiting
Clevidipine for treating high blood pressure after a brain bleed
This trial tests a blood pressure medicine called clevidipine given through an IV to people with a brain bleed (intracerebral hemorrhage). The goal is to see if quickly lowering blood pressure helps prevent more bleeding and improve recovery.
Irvine, CaliforniaAges 18–100 - NCT05843500Recruiting
CTEPD and CTEPH registry for long-term blood-clot lung disease
This study builds a registry to learn about people with chronic blood-clot lung disease (CTEPD/CTEPH) and what symptoms and test results look like over time. It may help clinicians better understand the condition and improve future care, since your participation supports data collection rather than a new drug.
San Francisco, CaliforniaAges 18 years+ - NCT07610278RecruitingPhase 2
Blood Pressure and Cholesterol Treatment Study
This study tests a combination of two new medications (QCZ484 and inclisiran) designed to lower both blood pressure and cholesterol levels. You may be a good fit if you have high blood pressure and high cholesterol that isn't fully controlled by current treatments.
Lincoln, CaliforniaAges 18–75 - NCT06274801RecruitingPhase 3
Long-term study of seralutinib for pulmonary arterial hypertension
This trial is for people with pulmonary arterial hypertension (PAH) who have already completed a previous study of the drug seralutinib. It offers continued access to the treatment so doctors can watch its safety and effects over a longer time.
Fresno, CaliforniaAges 18–75 - NCT06742723RecruitingPhase 3
Study of baxdrostat and dapagliflozin for kidney disease and high blood pressure

What taking part in a high blood pressure study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
