Transient Ischemic Attack clinical trials at University of California Health
4 research studies open to eligible people
Milvexian in Participants After an Acute Ischemic Stroke or High-Risk Transient Ischemic Attack- LIBREXIA-STROKE
open to eligible people ages 40 years and up
The purpose of this study is to evaluate whether milvexian compared to placebo reduce the risk of recurrent ischemic stroke.

Test Asundexian for Preventing a Stroke Caused by a Clot in Participants After an Acute Ischemic Stroke or After a High-risk Transient Ischemic Attack, a So-called Mini Stroke
open to eligible people ages 18 years and up
Researchers are looking for a better way to prevent an ischemic stroke which occurs when a blood clot travelled to the brain in people who within the last 72 hours had: - an acute stroke due to a blood clot that formed outside the heart (acute non-cardioembolic ischemic stroke), or - TIA/mini-stroke with a high risk of turning into a stroke (high-risk transient ischemic attack), and who are planned to receive standard of care therapy. Acute ischemic strokes or TIA/mini-stroke result from a blocked or reduced blood flow to a part of the brain. They are caused by blood clots that travel to the brain and block the vessels that supply it. If these blood clots form elsewhere than in the heart, the stroke is called non-cardioembolic. People who already had a non-cardioembolic stroke are more likely to have another stroke. This is why they are treated preventively with an antiplatelet therapy, the current standard of care. Antiplatelet medicines prevent platelets, components of blood clotting, from clumping together. Anticoagulants are another type of medicine that prevents blood clots from forming by interfering with a process known as coagulation (or blood clotting). The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care without increasing the risk of bleeding. The main purpose of this study is to learn whether asundexian works better than placebo at reducing ischemic strokes in participants who recently had a non-cardioembolic ischemic stroke or TIA/mini-stroke when given in addition to standard antiplatelet therapy. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Another aim is to compare the occurrence of major bleeding events during the study between the asundexian and the placebo group. Major bleedings have a serious or even life-threatening impact on a person's health. Dependent on the treatment group, the participants will either take asundexian or placebo once a day for at least 3 months up to 31 months. Approximately every 3 months during the treatment period, either a phone call or a visit to the study site is scheduled on an alternating basis. In addition, one visit before and up to two visits after the treatment period are planned. During the study, the study team will: - Check vital signs such as blood pressure and heart rate - Examine the participants' heart health using an electrocardiogram (ECG) - Take blood samples - Ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, the participants will be asked to complete a questionnaire on quality of life at certain time points during the study.

Platelet Expression of FcγRIIa and Arterial Hemodynamics to Predict Recurrent Stroke in Intracranial Atherosclerosis
open to eligible people ages 30 years and up
An observational study to determine if individuals with increased platelet FcyRIIa will have a higher risk of ischemic events.

Somatic Dysfunction in Patients With Acute Cerebrovascular Disease
open to eligible people ages 18 years and up
The goals of this observational study are to test the reliability of a new, standardized physical examination method to identify motion problems within joints or groups of joints among adult asymptomatic volunteers and in patients hospitalized with stroke or stroke-like episodes (e.g., transient ischemic attack, TIA). The main questions this investigation aims to answer are: - Can different, independent providers reliability quantify motion pattern problems using a systematic approach called, The Functional Pathology of the Musculoskeletal System (FPMSS) model? - Are there differences in joint(s) motion patterns among asymptomatic volunteers, patients with TIA (people with brain disease without new neurologic disability), and recent ischemic stroke (patients with new stroke-related-disability, e.g., paralysis)? - Is there an association between joint(s) motion impairment severity and stroke survivor outcomes? Participants (asymptomatic and those with stroke) will undergo a set of repeated paired, musculoskeletal physical exams by independent providers blinded to each other's assessments and patient information. Researchers will compare the severity, location, and quantity of joint(s) motion impairment between these three groups with the physical examination methodology (FPMSS). Clinical information (e.g., test results, diagnoses, brain imaging, medical history) will be collected from patients admitted for TIA and stroke. Enrolled participants with recent stroke will complete a survey three months after hospitalization to determine their self-perceived quality-of-life.
