Recruiting studies in California
- NCT06990867RecruitingPhase 2/Phase 3
Improving blood flow recovery after stroke
This trial tests a new approach to restore blood flow in the brain after a stroke. It aims to improve recovery and brain function in people with a blocked large artery.
Long Beach, CaliforniaAges 18–90 - NCT06870812Recruiting
Quick removal of brain bleed clot study
This trial tests a rapid procedure to remove a blood clot in the brain after a specific type of stroke. It might help people with a moderate-sized bleed in the front part of the brain if treatment can start within 24 hours.
Palo Alto, CaliforniaAges 18–70 - NCT06605014Recruiting
Body alignment after stroke or mini-stroke
This study looks at how a stroke or mini-stroke affects the body's natural movement and alignment (called somatic dysfunction). Researchers want to see if there are common patterns of tightness or imbalance after a stroke, which could help guide future treatments.
Sacramento, CaliforniaAges 18 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT06368648Recruiting
Study of a new forehead sensor for brain pressure monitoring
This study tests a new sensor that measures brain pressure from outside the head. It is for people who are already in the hospital getting their brain pressure and blood pressure monitored continuously.
Sacramento, CaliforniaAges 18 years+ - NCT06289985Recruiting
Expanding clot removal for medium vessel strokes
This trial tests a new approach to see if removing clots from medium-sized brain blood vessels can help more patients recover from stroke. It aims to expand the use of a standard clot-removal procedure to people with less severe symptoms or blockages in smaller vessels.
La Jolla, CaliforniaAges 18 years+ - NCT06039176Recruiting
Learning from the HeartMate 3 device
This study looks at information from the HeartMate 3 LVAD device to learn more about how it works and what it can tell us about the future. It may help people with advanced heart failure who need this specific device.
San Francisco, CaliforniaAges 18–100 - NCT06029491Recruiting
Studying a new suction device for stroke treatment
This trial tests a new device that removes blood clots in the brain using suction. It is for people having a large-vessel ischemic stroke who can be treated within 8 hours of symptoms starting.
Torrance, CaliforniaAges 18–80 - NCT05963698Recruiting
Closing off a heart pouch to prevent stroke
This study tests a procedure that seals off the left atrial appendage (a small heart pouch) to help prevent stroke in people with atrial fibrillation. You may be considered if your stroke risk is high and you are already on blood-thinner medicine.
Fountain Valley, CaliforniaAges 18 years+ - NCT05868525RecruitingPhase 4
Compare two aspirin doses after blunt vessel injury
This trial tests whether taking a lower-dose aspirin (81 mg) works as well as a higher-dose aspirin (325 mg) to prevent stroke after a blunt injury that affects blood vessels in the neck/head. It may help some patients lower their stroke risk with the simplest, safest dose.
Loma Linda, CaliforniaAges 18 years+ - NCT05531461Recruiting
Imaging study after clot removal with Tigertriever device
This study looks at brain images and thinking (cognition) after treatment to remove a large artery blood clot using the Tigertriever. It may help doctors understand how well the procedure works and how it affects long-term brain function.
Los Angeles, CaliforniaAges 18–75 - NCT04144972Recruiting
Closed-loop deep brain stimulation for long-lasting nerve pain
This trial tests a “smart” deep brain stimulation device that senses your brain signals and adjusts treatment to reduce severe, long-lasting pain. It may help people whose pain has not improved with multiple pain medicines and surgery cannot fix the cause.
San Francisco, CaliforniaAges 22–80 - NCT04045665RecruitingPhase 3
Blood thinner vs usual care for new heart rhythm after bypass surgery
This trial tests whether using a blood thinner in people with new, temporary atrial fibrillation after CABG (heart bypass surgery) can reduce harmful outcomes compared with standard treatment. It may help prevent stroke or other complications if your rhythm problem fits the trial’s timing and risk profile.
Los Angeles, CaliforniaAges 18 years+ - NCT03907046RecruitingPhase 3
Blood thinner study to prevent stroke after brain bleed
This Phase 3 study tests whether a blood thinner (apixaban) can help prevent another stroke and support recovery after you’ve had a brain bleed. You would be assigned to a treatment group, and the study checks safety and whether strokes can be reduced without causing dangerous bleeding.
Castro Valley, CaliforniaAges 18 years+ - NCT03698149Recruiting
Brain-signal training for hand and speech control after disability
This study tests whether recording brain signals can help people regain better control of movements in the arms and help with speech. It may be an option for people with significant disability from certain nerve and brain conditions who can safely take part in brain-monitoring procedures.
San Francisco, CaliforniaAges 21 years+ - NCT02638701RecruitingPhase 1/Phase 2
Infliximab for hard-to-treat brain blood vessel aneurysms
This Phase 1/2 trial tests infliximab, a medicine that calms inflammation, for dolichoectactic aneurysms in the vertebral/basilar brain blood vessels that usually cannot be treated with standard surgery or procedures. The goal is to see if it can improve safety and how the aneurysm behaves over time.

What taking part in a stroke 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 stroke clinical trials in California?
- Yes. We're currently tracking 64 recruiting stroke 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 stroke 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 stroke 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?
New stroke studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
