Recruiting studies in California
- NCT05948566RecruitingPhase 2
Improving response to stroke treatment with an antibody drug
This Phase 2 trial tests an antibody treatment (TS23) given to people with a suspected acute ischemic stroke to improve how well they respond to stroke care. You may qualify if your stroke scan shows the right pattern of injured brain tissue and if the study drug can be given within a short time window after symptoms start.
Los Angeles, CaliforniaAges 18 years+ - NCT06116630Recruiting
Brain health after stroke risk factors study
This study looks at how well the brain works after a stroke or in people with stroke risk factors. It uses a special MRI scan to understand brain changes that may affect thinking and memory.
Palo Alto, CaliforniaAges 45–90 - NCT06226493Recruiting
Vagus Nerve Stimulation for Stroke Recovery
This early-stage study tests if putting a mild electrical pulse on the vagus nerve (a nerve in the neck) can help the brain heal after a first-time stroke. It looks for changes in brain activity and certain DNA markers to understand how the treatment works.
Pomona, CaliforniaAges 18–80 - NCT06226805RecruitingPhase 2
Testing BB-031 for recent ischemic stroke
This study tests an experimental drug called BB-031 to see if it can safely help people who have had a recent ischemic stroke (a clot that blocks blood flow to the brain). The trial is for people who can get to the hospital within 24 hours of their first symptoms and have a moderate to severe stroke.
Burlingame, CaliforniaAges 18 years+ - NCT06386874Recruiting
Magnetic field therapy for arm recovery after stroke
This study tests a new magnetic device applied to the head to help improve arm function after a stroke. You will use the device while doing exercises, and a caregiver will support you with a mobile app and video calls.
Downey, CaliforniaAges 22–80 - NCT06440707RecruitingPhase 2
Brain stimulation for recent stroke recovery
This trial tests a safe, non-invasive brain stimulation technique called tDCS to help people recover from a recent stroke. It's for people who cannot have the standard clot-removal procedure and who can start treatment within 24 hours of their stroke.
Los Angeles, CaliforniaAges 18 years+ - NCT06672107Recruiting
Driving simulator training after stroke
This study tests if using a driving simulator can help improve driving skills in veterans who have had a stroke. If you are a veteran who had a stroke at least 3 months ago and are between 40 and 80 years old, this program might help you get back behind the wheel safely.
Sacramento, CaliforniaAges 40–80 - NCT06682429Recruiting
Home rehab program after stroke
This study tests a home-based therapy program delivered by video calls to help people recovering from a stroke improve arm function. It is designed for those with moderate arm weakness about 4 months after their stroke.
Downey, CaliforniaAges 18–80 - NCT06722755Recruiting
CPAP for Sleep Apnea After Stroke
This study tests whether using a CPAP machine (a device that helps you breathe while sleeping) can improve recovery after a recent stroke or brain bleed. You may join if you had a stroke in the past month and are not already using CPAP.
Downey, CaliforniaAges 18 years+ - NCT06752707Recruiting
MiGo Tracker: home exercise monitoring after stroke
This study tests a wearable device called MiGo Tracker that tracks your arm and hand movements during home exercises after a stroke. It helps your therapist see how you're doing and adjust your rehab.
Downey, CaliforniaAges 18 years+ - NCT07172464Recruiting
Study of a new device to close a hole in the heart after a stroke
This trial tests a new device to close a PFO (a small hole between the upper chambers of the heart) in people who have had a stroke caused by a blood clot. The goal is to prevent future strokes by blocking the hole.
Los Angeles, CaliforniaAges 18–65 - NCT07681102Enrolling by invitation
Brain stimulation for arm recovery after stroke
This study tests a new type of brain stimulation to help people who have had a stroke and still have limited arm movement. The goal is to see if a specific pattern of stimulation can improve recovery more than others.
Berkeley, CaliforniaAges 18–80 - NCT07614074Recruiting
Understanding Recovery from Coma and Unconsciousness
This study follows patients who have been in a coma (deep unconsciousness) for at least 24 hours due to a brain injury. Researchers will track how patients recover over time to better understand which factors help predict who will wake up and how well they'll recover.
San Francisco, CaliforniaAges 18 years+ - NCT06961487Enrolling by invitation
Stroke treatment trial for large area brain damage
This trial tests if a procedure to remove a large blood clot from the brain (called a thrombectomy) can help people with severe strokes who have a large damaged area. It is for people who can be treated within 24 hours of their stroke starting.
Palo Alto, CaliforniaAges 18–90 - NCT06040255Enrolling by invitationPhase 4
Steroid treatment for focal brain artery inflammation in children
This trial tests whether short-term steroids improve recovery for children who recently had a stroke or mini-stroke caused by inflammation of a brain artery. If you qualify, you would receive steroids and follow-up imaging to see if it helps prevent further damage.
San Francisco, CaliforniaAges 1–18 - 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 - NCT07143019Recruiting
A new device for treating wide-necked brain aneurysms
This trial tests a special device (p48/64 MW HPC) to treat certain brain aneurysms that are wide-necked or have a shape that makes them hard to treat. It might help people with aneurysms that haven't ruptured or that have been treated before and are now coming back.
San Francisco, 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+ - NCT07528261Recruiting
Support Group for Family Caregivers of Stroke Survivors
This study tests whether a support group using acceptance and commitment therapy (a type of counseling that helps people cope with stress) can reduce caregiver burden and distress. You would meet online with other people caring for stroke survivors.
Alameda, CaliforniaAges 40 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+ - 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+ - 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+ - 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 - NCT05531461Recruiting

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.
