Your DNA could determine which heart drug works best
NCT ID NCT03161678
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This trial investigates whether a common genetic variation in the CES1 gene affects how the body processes two antiplatelet drugs, clopidogrel and ticagrelor. Healthy volunteers of Amish descent will take each drug for eight days in a crossover design, and researchers will measure platelet function before and after treatment. The goal is to see if genetic differences can predict which drug works better for a given person, potentially paving the way for personalized antiplatelet therapy.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- clopidogrel and ticagrelor
- What this could lead to
- If genetic differences are found to matter, doctors could one day choose the right antiplatelet drug based on a person's DNA, potentially preventing heart attacks and strokes more effectively.
- What could go wrong
- This is a small, early-stage study in healthy volunteers, not patients. The results may not apply to real-world heart attack patients, and the genetic effect may be too small to guide treatment.
