Recruiting studies in California
- NCT03318432Recruiting
Stroke recovery research registry for people with ongoing symptoms
This study is a registry that enrolls adults who have had a stroke and still have symptoms. It helps researchers learn about stroke recovery over time and may connect you to future stroke research studies.
San Francisco, CaliforniaAges 18 years+ - NCT05911568Recruiting
Clot-removal treatment for stroke patients with existing disability
This trial studies whether an endovascular (catheter-based) procedure to treat a certain type of blocked artery can improve outcomes for people who already had trouble functioning before their stroke. You may be considered if your stroke is confirmed early and your scans show the right type and location of blockage.
Los Angeles, CaliforniaAges 18 years+ - NCT07631078Recruiting
Transcranial magnetic stimulation plus therapy for arm recovery after stroke
This trial tests a new type of brain stimulation combined with physical therapy to help people who have had a stroke regain arm and hand movement. It's for individuals who have some movement but could still improve, at least a year after their stroke.
San Francisco, CaliforniaAges 18–80 - NCT05338697Recruiting
Early testing after stroke to predict recovery outcomes
This study checks early brain and arm/hand signals soon after a stroke to better predict how well people recover by about 90 days. It may help future, better-targeted stroke recovery studies by improving how recovery chances are measured early.
Los Angeles, CaliforniaAges 18 years+ - NCT05065216RecruitingPhase 2/Phase 3
Study drug for acute ischemic stroke started within 24 hours
This trial tests whether an investigational study drug can improve outcomes after an acute ischemic stroke (a stroke caused by blocked blood flow). You may be eligible if you are able to start treatment quickly after symptom onset and have a moderate stroke severity on a standard stroke exam.
Arcadia, CaliforniaAges 18–90 - NCT07491952Recruiting
Continuous Dual Aspiration for Stroke With Zoom System
This trial tests a new way to remove blood clots from the brain using the Zoom System with a continuous double-suction technique (CDAT). It aims to see how well this approach works for people having a stroke caused by a large vessel blockage.
Walnut Creek, CaliforniaAges 18 years+ - NCT06999122Recruiting
Testing a new helmet-style brain scanner for stroke bleeding
This trial tests a new type of brain scanner (similar to a helmet) that looks for bleeding in the brain without radiation. It is for people who have had stroke-like symptoms in the last 24 hours and have not yet received treatment.
Los Angeles, CaliforniaAges 22 years+ - NCT06692686Recruiting
Testing ankle braces to improve walking after stroke
This trial is studying how different types of ankle braces (AFOs) affect walking ability in people who have had a stroke. It may help find the best brace to improve mobility.
Downey, CaliforniaAges 18 years+ - NCT05691244RecruitingPhase 3
Tested drug for acute ischemic stroke within 24 hours
This Phase 3 trial studies sovateltide (and a placebo) in adults with an ischemic stroke, aiming to improve safety and outcomes. It focuses on people who can start treatment quickly after stroke symptoms begin and who do not have bleeding in the brain on imaging.
Carmichael, CaliforniaAges 18–80 - NCT05518305Recruiting
Predicting recurrent stroke risk in people with artery narrowing
This study looks at blood markers and brain/artery scan results to predict who with intracranial artery narrowing is more likely to have another stroke. It may help doctors spot higher-risk people earlier and better target prevention.
Los Angeles, CaliforniaAges 30 years+ - NCT03399929Recruiting
Tracking long-term recovery after brain injury or stroke
This study looks at how people do over the long term after a stroke or a traumatic brain injury (brain injury from an accident). It may help researchers understand recovery and improve future support and care.
Encino, 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 - NCT07756476Recruiting
Fluid treatment guided by heart response for acute pancreatitis
This study tests whether giving IV fluids based on how your heart responds can improve recovery from acute pancreatitis, compared with usual care. It may help your body handle fluids better during treatment.
Los Angeles, CaliforniaAges 18–75 - NCT07737873Recruiting
Movement and brain function after chronic stroke
This study looks at how stroke affects your movement and nervous system over time. You will do simple movement tests and answer quality-of-life surveys to help researchers understand how to improve recovery.
Sacramento, CaliforniaAges 18 years+ - 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+ - NCT05625438Recruiting
Home video therapy for early arm recovery after stroke
This study tests a home-based (telerehabilitation) program to help people practice arm movement after a recent stroke (or certain brain injuries). It may help improve arm function when started soon after symptoms begin.
Fullerton, 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 - NCT07430917RecruitingPhase 2
Testing J147 for recent stroke from blocked artery
This trial tests a new drug, J147, for people who recently had a stroke caused by a blocked artery and have already had a procedure to reopen that artery. It aims to see if the drug can improve recovery.
Long Beach, CaliforniaAges 18–90 - NCT07392450RecruitingPhase 2
Study of TAK-755 for adults with acute ischemic stroke
This trial tests if TAK-755 can help people who have had a moderate to severe stroke within the last 24 hours. It aims to see if the drug can improve recovery by protecting brain tissue that is still salvageable.
San Francisco, 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 - NCT07042152Recruiting
Wearable device and coaching to improve arm use after stroke
This study tests whether a wearable device that tracks arm movement, plus coaching to use your weaker arm more, can help you recover better after a stroke. It's for people who are at least 6 months past their stroke and have some arm weakness but can still use their hand.
Irvine, CaliforniaAges 18–84 - NCT06961487Enrolling by invitation
Stroke treatment trial for large area brain damage

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.
