Study of PF-07328948 for adults with heart failure
This trial tests a new medicine, PF-07328948, for adults with heart failure to see if it can improve symptoms and daily life. It is for people who have had heart failure for at least 3 months and can walk without too much difficulty.
Lake Forest, CaliforniaAges 18–79 - NCT06024746RecruitingPhase 3
Finerenone plus SGLT2i for hospitalized heart failure
This trial tests whether adding two heart medicines together (finerenone and an SGLT2 inhibitor) helps people who are in the hospital for heart failure recover better. It may be an option for you if you are currently hospitalized and your heart stress markers are high.
Chula Vista, CaliforniaAges 18 years+ - NCT04196842Recruiting
Heart failure precision medicine study using heart tests and blood tests
This study looks at how “personalized” (precision) treatment planning for heart failure may work, using results from heart imaging (echocardiogram) or a blood test called B-type natriuretic peptide. You may join if you have heart failure and can follow frequent study check-ins.
Sacramento, CaliforniaAges 21 years+ - NCT06935370RecruitingPhase 3
Testing vicadrostat with empagliflozin for heart failure with weak pump
This trial tests a new drug called vicadrostat combined with another drug, empagliflozin, for people with heart failure and a weak heart pump. It aims to see if this combination helps improve symptoms and outcomes.
Beverly Hills, CaliforniaAges 18 years+ - NCT07217366Enrolling by invitation
Speech-to-text tool for heart failure patients
This study tests a speech-to-text tool to help people with heart failure report their symptoms and health information more easily. It aims to see if using voice instead of typing can improve data collection.
Palo Alto, CaliforniaAges 18 years+ - NCT06307652RecruitingPhase 3
Testing a new heart failure and kidney treatment combo
This study tests a new combination of two medicines (balcinrenone and dapagliflozin) for people with heart failure and reduced kidney function. The goal is to see if this combination helps improve heart and kidney health better than current treatments.
Beverly Hills, CaliforniaAges 18–130 - NCT06979362RecruitingPhase 2
Testing a new medicine for heart failure with thickened heart muscle
This study tests an experimental medicine, CDR132L, to see if it can improve heart structure and function in people with a type of heart failure where the heart muscle is thickened. If you have heart failure with normal pumping function and thickened heart walls, this trial may offer access to a new potential treatment.
La Jolla, CaliforniaAges 40–84 - NCT07761117RecruitingPhase 3
Heart failure treatment study for people with preserved pumping function
This study tests an investigational medication called elecoglipron to see if it can improve heart and blood vessel outcomes in people with heart failure with preserved or mildly reduced ejection fraction. If you join, you will receive either the study drug or a placebo, and your heart health will be monitored over time.
San Diego, CaliforniaAges 18 years+ - NCT05996328Recruiting

What taking part in a heart failure 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.

Common questions
- Are there heart failure clinical trials in California?
- Yes. We're currently tracking 87 recruiting heart failure studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a heart failure study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a heart failure trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
