CLARITY

What is Clarity?

Clarity is a stroke prevention study looking into a medicine called cilostazol (pronounced suh·laa·stuh·zaal).

Cilostazol is already FDA-approved for problems with blood vessels in the legs.

Adding cilostazol to current stroke prevention treatments may lower the risk of having another stroke, but more information is needed to be sure.

Clarity will enroll 2,000 stroke survivors from across the United States to find out if cilostazol helps prevent future strokes.

How can Clarity help me?

Routine visits to monitor your health:

• Clarity may help you stay engaged with your medical care.
• Clarity may allow you to discuss more about healthy habits that can help lower the risk of future strokes.

What can I expect?

You will be asked to:

• Take the medicine you are randomly assigned to: either cilostazol or a placebo (inactive pill).

• Attend visits every 3 months for the duration of the study (2 to 5 years).

• Complete short health surveys.

How we support you:

• Flexible visits in-person or by phone.

• The study medicine is available at no charge and will be mailed directly to you.
