Aspirin plus one blood thinner versus aspirin plus clopidogrel
This trial compares two common “blood thinner” combinations to prevent problems after a PCI procedure for complex blocked heart arteries. It may help your care team find which combination works better for people with higher-risk artery patterns.
SeoulAges 19–75 - NCT04214990RecruitingPhase 3
Aspirin after early stomach precancer or early cancer removal
This trial tests whether taking aspirin after endoscopic removal of an early stomach condition can lower the chance of the cancer coming back or progressing. You may be considered if your early stomach findings were fully removed and you’re able to avoid certain medications that raise bleeding risk.
BusanAges 19–70 - NCT05347069RecruitingPhase 4
Aspirin study for people with stable heart artery disease
This trial tests whether daily aspirin is safe and effective for people who have stable (chronic) coronary artery disease but cannot have procedures to open blocked arteries. It may help reduce future heart problems, while also checking for side effects and risks from aspirin.
KyotoAges 20 years+ - NCT05633810RecruitingPhase 3
Testing colchicine plus coated aspirin to prevent heart events
This Phase 3 study tests whether colchicine and a special type of aspirin can lower the risk of future heart attacks, strokes, or other major heart problems in people with type 2 diabetes who have not had a prior heart event. It aims to reduce cardiovascular risk using medicines that may calm inflammation and protect blood vessels.
Bentley, Western AustraliaAges 55–80 - NCT06111079RecruitingPhase 3
Stopping Aspirin in High-Risk Pregnant Women
This trial tests whether stopping aspirin use in high-risk pregnant women can be safe. It aims to find the best time to stop taking aspirin to prevent preeclampsia, a condition that causes high blood pressure during pregnancy.
Guangzhou, GuangdongAges 18–45 - NCT06185621Recruiting

Common questions
- Are there clinical trials studying Aspirin?
- Yes. Clin2 currently lists 137 recruiting studies that include Aspirin, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Aspirin trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Aspirin an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Aspirin or a specific trial is right for you.
