Phase 2/3

Research Study on Aspirin Resistance and Stroke Risk

We are conducting a study to learn more about how aspirin and similar medications work for people with past stroke or related conditions. We will use a test called Platelet Function Analysis (PFA) to see if it helps predict outcomes like stroke or bleeding.

  • Time Commitment: The study involves multiple visits for platelet tests.
  • Eligibility: You must be currently taking aspirin or Plavix, and have had a stroke, mini-stroke (also called TIA, or transient ischemic attack), or a similar condition.
  • Goal: To find out if adjusting medication doses based on PFA results could be safer and more effective.

Your participation could help us understand more about how these medications work and how to use them better in the future. If you are 18 or older and meet the criteria, you might be eligible to join this important study. 🏥

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
