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.
San Diego, 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 - 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+ - NCT07631078Recruiting
Brain Stimulation to Improve Arm Movement After Stroke
This pilot study tests whether a combination of brain stimulation (TMS) and physical therapy can help improve arm and hand function in people who had a stroke at least one year ago. The goal is to see if this approach helps patients regain better control and strength in their affected arm.
San Francisco, CaliforniaAges 18–80 - 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+ - 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+ - 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+ - 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+ - 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.
Oxnard, CaliforniaAges 18–80 - 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+ - 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 - NCT06402968Recruiting
Clevidipine for treating high blood pressure after a brain bleed
This trial tests a blood pressure medicine called clevidipine given through an IV to people with a brain bleed (intracerebral hemorrhage). The goal is to see if quickly lowering blood pressure helps prevent more bleeding and improve recovery.
Irvine, CaliforniaAges 18–100 - 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 - 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+ - 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+ - NCT03737786Recruiting
Sedation with collateral support for stroke clot removal
This trial tests a specific sedation approach, along with support during the procedure, for people having emergency clot removal (mechanical thrombectomy) for a certain type of acute ischemic stroke. It may help make the procedure safer and more effective by improving how patients are managed during endovascular treatment.
Los Angeles, CaliforniaAges 18–110 - NCT03821129Recruiting
Reduce recurrent stroke with a PFO closure device and antiplatelet pills
This study looks at whether closing a heart opening called a patent foramen ovale (PFO) with a special septal occluder, along with antiplatelet medications, can lower the risk of another stroke. It is for people who recently had a stroke thought to be caused by a clot that traveled from the heart but without another clear source.
La Jolla, CaliforniaAges 18–70 - NCT03968393RecruitingPhase 4
Blood thinner to prevent stroke after stress-related irregular heartbeats
This trial tests whether taking a blood thinner can lower the risk of stroke in people who had atrial fibrillation (an irregular heartbeat) that happened temporarily around a stressful illness or surgery. It looks especially at people at higher risk for stroke after that episode.
Los Angeles, CaliforniaAges 55 years+ - NCT04829071RecruitingEarly Phase 1
Testing brain and movement training after a one-sided stroke
This early research study looks at a way to improve thinking and movement after a stroke that happened more than 6 months ago. It may help people who still have problems using one side of their body to walk and learn new movement skills.
Los Angeles, CaliforniaAges 45–85 - NCT04916210Recruiting
Study how stroke type affects thinking and recovery
This study looks at what predicts memory and thinking problems after different types of stroke or brain bleeding, and how blood-vessel changes relate to recovery. You may be invited if you recently had a stroke/bleed and can complete a baseline check within 6 weeks.
Los Angeles, CaliforniaAges 18 years+ - NCT04994756Recruiting
Stroke and brain blood-vessel procedure registry study
This study collects information from people who undergo a procedure for a problem in brain or blood vessels (such as stroke-related vessel blockage). It does not test a new drug; it helps doctors understand outcomes and care patterns after these procedures.
Santa Barbara, CaliforniaAges 1–120 - NCT05611242RecruitingPhase 3
Thrombectomy for acute stroke caused by blocked neck and brain arteries
This Phase 3 trial studies whether removing a clot using a catheter (endovascular thrombectomy) works better for certain types of acute ischemic stroke. It focuses on people with a blocked neck artery plus a blockage in the brain, and who can’t get or didn’t respond to IV clot-busting medicine.
Pomona, CaliforniaAges 18–79 - 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.

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.
