Researchers at Mayo Clinic at Jacksonville, led by Dr. Michelle Lin, MD, MPH are recruiting for a prospective, observational nested pilot randomized controlled study to discover retinal biomarkers that would predict cerebral small vessel disease progression, and evaluate the safety/efficacy of cilostazol in slowing SVD progression. Twenty CADASIL patients are being recruited for this interventional drug trial.

You may be eligible to participate if:

  • You are at least 18 years old
  • Confirmed or suspected diagnosis of CADASIL
  • Age-matched healthy control (eg. CADASIL patient’s spouse or friend without small vessel disease of a similar age)
  • Ability to travel to study location (no reimbursement available)

Participation requires a half day of testing and a follow-up visit with the same tests in 1 year apart. Study tests include MRI, blood draw, retinal imaging, cognitive testing, and physician visit.

For more information, please contact the study coordinator Ed Michel at 904-953-4519 or

CureCADASIL is collaborating with members of the Clinical Genome Resource (ClinGen) team to share genetic and health information from patients affected by CADASIL through the ClinGen Patient Data Sharing Program. This information will be collected through the CureCADASIL Family Registry.

Why is data sharing needed?

When a laboratory finds a genetic change (variant) for the first time, often little is known about it. Even if a genetic variant is well understood, data sharing helps increase understanding of a condition’s features, which may help identify possible interventions and treatments. The more information collected, the better researchers will understand how genes affect health and, ultimately, how best to care for patients.

Complete these 3 steps to participate:

1. Login to your account (or create an account if you have not) at: CureCADASIL Family Registry.

2. Review and complete the ClinGen Data Sharing Program informed consent.

3. Upload a copy of your genetic test report to your account, if you have not already. If you need help getting a copy of your genetic test, contact ClinGen at

For questions about the research study, call or email ClinGen at or 570-214-1721 (toll free 855-322-7683)

An observational research study led by Dr. Fanny Elahi, MD, PhD at the University of California San Francisco is seeking participation by CADASIL patients. The VascBrain study is a longitudinal study developing novel neuroimaging (images of the structure or activity of the brain) and serological biomarkers (obtained through analysis of bloodwork) to improve early detection and diagnosis of cerebrovascular disease. Annual participation requires 2 days of testing that do not have to be consecutive. Study tests include MRI, blood draw, retinal imaging, cognitive testing, and physician visit.

Participation requirements include:

  • Confirmed or suspected diagnosis of CADASIL (by genetic test or skin biopsy)
  • Ability to travel to study location (no reimbursement available)
  • Ability to cooperate with and understand medical tests
  • No pacemakers or metal implants

For additional information on participation please contact the study coordinator Sasha Saias ( and Dr. Fanny Elahi (

This study is sponsored by the NIH, National Heart, Lung, and Blood Institute (NHLBI). The study is currently recruiting and ongoing. Adults age 18 years and older can join.

CADASIL Disease Discovery Study

cureCADASIL is aware of three CADASIL Tissue Banks in the US supported by brain and tissue donations by surviving families of CADASIL patients. For researchers interested in CADASIL tissue for research, please contact cureCADASIL for requests.

Completed Studies


Results are expected in 2021. Thank you for your participation.

Researchers at Mayo Clinic at Jacksonville and The University of Utah are searching for people who are affected by both CADASIL and headaches. The purpose of this research study is to further understand the cause of headaches in this serious and rare condition.

Understanding Clinical Trials

Although there are many definitions of clinical trials, they are generally considered to be biomedical or health-related research studies in human beings that follow a pre-defined protocol. includes both interventional and observational types of studies globally. Interventional studies are those in which the research subjects are assigned by the investigator to a treatment or other intervention, and their outcomes are measured. Observational studies are those in which individuals are observed and their outcomes are measured by the investigators.

Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research.

All clinical trials have guidelines about who can participate. Using inclusion/exclusion criteria is an important principle of medical research that helps to produce reliable results. The factors that allow someone to participate in a clinical trial are called “inclusion criteria” and those that disallow someone from participating are called “exclusion criteria”. These criteria are based on such factors as age, gender, the type and stage of a disease, previous treatment history, and other medical conditions. Before joining a clinical trial, a participant must qualify for the study. Some research studies seek participants with illnesses or conditions to be studied in the clinical trial, while others need healthy participants. It is important to note that inclusion and exclusion criteria are not used to reject people personally. Instead, the criteria are used to identify appropriate participants and keep them safe. The criteria help ensure that researchers will be able to answer the questions they plan to study.
