Bakersfield, CaliforniaAges Any age - NCT07207811RecruitingPhase 3
Coramitug for heart failure caused by ATTR amyloidosis
This trial tests a new medicine called Coramitug for people with heart failure due to ATTR amyloidosis, a condition where abnormal proteins build up in the heart. The study aims to see if Coramitug can improve heart function and quality of life.
La Jolla, CaliforniaAges 18 years+ - NCT06812533Recruiting
Testing a new approach for heart failure with weak pump
This study tests a new device or procedure to help people with heart failure and a weak heart pump. If you have a low ejection fraction and are on standard medications, you may be able to join.
Los Angeles, CaliforniaAges 18 years+ - NCT05685303Recruiting
Testing a treatment for heart failure symptoms with normal pumping ability
This study is looking at a new treatment for people with heart failure where the heart’s pumping strength is not reduced much (HFpEF or HFmrEF), but pressure inside the heart is high during exercise. It may help relieve symptoms in people who still feel unwell during normal activity despite stable standard treatment.

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 83 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?
