TrondheimAges 18 years+ - NCT06168461RecruitingEarly Phase 1
Can daily aspirin help after preeclampsia?
This study tests whether taking a low-dose aspirin every day can help improve blood vessel health in people who had preeclampsia within the past 5 years. The goal is to see if aspirin can lower the risk of future heart problems.
Iowa City, IowaAges 18–50 - NCT06281665RecruitingPhase 4

This trial tests whether taking low-dose aspirin after giving birth can help people who had preeclampsia. It aims to see if aspirin can lower the risk of future heart problems.
Pittsburgh, PennsylvaniaAges 18–55 - NCT06336174Recruiting
Thinking and Memory in Brain Artery Narrowing: A Study
This study looks at how severe narrowing of brain arteries may affect memory and thinking over time. It involves people who have had a mini-stroke or mild stroke and aims to understand the changes in cognitive function.
Hefei, AnhuiAges 18–80 - NCT06451198RecruitingPhase 4
Indobufen vs aspirin after stent in older heart patients
This trial tests whether a blood thinner called indobufen works as well as aspirin for older people (65+) who have had a heart attack or unstable angina, received a drug-eluting stent, and are already taking two blood thinners. The goal is to find a safer or better option for long-term prevention.
Shanghai, Shanghai MunicipalityAges 65 years+ - NCT06530537RecruitingPhase 3
Cilostazol vs. Aspirin for recent stroke with brain microbleeds
This trial compares two medications—cilostazol and aspirin—to see which is better at preventing another stroke in people who have had a recent clot-caused stroke and also have tiny spots of bleeding in the brain (microbleeds). It aims to find a safer and more effective treatment for this specific group.
Hangzhou, ZhejiangAges 35 years+ - NCT06591338RecruitingPhase 3
Aspirin plus ticagrelor or clopidogrel for minor stroke
This trial tests whether adding aspirin to either ticagrelor or clopidogrel (two antiplatelet medicines) can help prevent another stroke in people who recently had a minor stroke or TIA affecting a large brain artery. It is for people who started antiplatelet treatment within 24 hours of their symptoms.
Kafr ash ShaykhAges 18–75 - NCT06591377RecruitingPhase 3
Aspirin plus a second drug for minor stroke or TIA
This trial tests whether adding ticagrelor or cilostazol to aspirin is better than aspirin alone for preventing another stroke. It is for patients who recently had a minor stroke or a transient ischemic attack (TIA) caused by a blockage in a large artery.

- How do I know if I qualify for a aspirin trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a aspirin trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
