Recruiting studies
- NCT06100510Enrolling by invitationPhase 4
Platelet function test in healthy adults
This trial is collecting blood from healthy adults to establish a new reference range for a standard platelet function test. You may be eligible if you do not have any bleeding disorders, are not taking blood thinners or anti-inflammatory medications, and meet other lab criteria.
East Syracuse, New YorkAges 18 years+ - NCT03378934RecruitingPhase 4
Berberine after stent placement to reduce blood-platelet effects
This trial studies whether berberine changes how strongly your platelets “stick together” after a coronary stent. It may help reduce risk related to clotting while you continue standard heart medicines (aspirin and clopidogrel).
Beijing, Beijing MunicipalityAges 18–70 - NCT05997693RecruitingPhase 3
One month of blood thinners after heart bypass surgery
This trial tests whether taking just one month of two blood thinners after coronary artery bypass graft (CABG) surgery is safe and as effective as the standard longer course. It focuses on people having their first bypass surgery who receive at least one vein graft from the leg.
Englewood, New JerseyAges 18 years+ - NCT05955365RecruitingPhase 4
Single anticoagulant blood thinner after stent in atrial fibrillation
This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.
HasseltAges 18 years+ - NCT05681702RecruitingPhase 4
Personalizing medicines to reduce bleeding after stent procedure
This trial studies ways to reduce bleeding in people after a stent procedure (PCI) who have been taking two anti-platelet medicines (aspirin plus prasugrel or ticagrelor) for a set amount of time. It may help find a safer plan for preventing blood clots while lowering bleeding risk.
Jacksonville, FloridaAges 18 years+ - NCT05643651RecruitingPhase 4
Rivaroxaban for kids with large heart artery aneurysms after Kawasaki disease
This trial studies whether rivaroxaban (a blood thinner) can help prevent dangerous clots in children age 2 and older who have “giant” coronary artery aneurysms after Kawasaki disease. Doctors will see if it’s safe and tolerable for children who are also on standard anti-clot/anti-platelet medications for the next 3 months.
Shanghai, Shanghai MunicipalityAges 2–18 - NCT05577988RecruitingPhase 3
Genetic-guided weaker blood thinner vs stronger standard therapy
This study tests whether switching early to a weaker anti-platelet medicine based on your genetics can reduce bleeding problems in people at high risk for bleeding after a heart attack. It compares this approach to the usual strategy of staying on a stronger anti-platelet medicine.
Paris, IDFAges 18 years+ - NCT05418556RecruitingPhase 4
Comparing antiplatelet strategies after heart stent
This study compares two ways of choosing blood thinners after a heart stent procedure. It aims to see if using an imaging-guided strategy leads to better outcomes than usual care.
Bucheon-siAges 19 years+ - NCT05283356RecruitingPhase 4
Ticagrelor or aspirin after heart valve replacement
This trial compares two blood thinners (ticagrelor and aspirin) to see which one works better at preventing blood clots after a less-invasive heart valve replacement (TAVI). It is for people with severe aortic stenosis who also have diabetes, heart disease, or artery disease.
Vigo, PontevedraAges 18 years+ - NCT05287321RecruitingPhase 3
Aspirin plus hydroxychloroquine to prevent preeclampsia in high-risk pregnancy
This trial tests whether adding aspirin and hydroxychloroquine can lower the risk of preeclampsia during pregnancy in people considered high-risk. If you qualify, you may be assigned to take the study medicines to help protect you and the baby.
SeoulAges 19–50 - NCT04796714RecruitingPhase 4
Aspirin and clopidogrel after left heart appendix closure
This trial studies a “double anti-platelet” medicine plan (aspirin plus clopidogrel) after closing the left atrial appendage, a procedure used to reduce stroke risk in some heart rhythm conditions. It aims to find a safer, better medicine strategy for people who cannot take standard blood thinners.
PessacAges 18 years+ - NCT04695106RecruitingPhase 4
Blood Thinner and Heart Attack Prevention Study
This study tests whether taking dabigatran (a blood thinner) combined with ticagrelor (a blood clot preventer) is safe and effective for patients with irregular heart rhythm (atrial fibrillation) who recently had a heart attack and received a stent. The goal is to prevent future blood clots while minimizing bleeding risks.
Gdansk, Pomeranian VoivodeshipAges 18 years+ - NCT04770012RecruitingPhase 3
Aspirin or clopidogrel after heart transplant
This study tests antiplatelet medicines (like aspirin or clopidogrel) in people who have had a heart transplant. The goal is to see if these medicines can safely help prevent blood-related complications after transplant.
Vancouver, British ColumbiaAges 18 years+ - NCT04381936RecruitingPhase 3
Testing COVID-19 or pneumonia treatments in hospitalized patients
This trial tests different treatments for serious lung infections in people who are already in the hospital. It may help doctors learn which treatment works best for recovery and survival when pneumonia-like illness is suspected.
BrusselsAges birth+ - NCT04464070Enrolling by invitationEarly Phase 1
Study of how your body processes natural inflammation signals
This early study looks at how the body breaks down certain natural inflammation-related chemicals (“eicosanoids”). It aims to understand normal metabolism pathways, and you may help by sharing how your body responds while you avoid certain medicines.
Nashville, TennesseeAges 18–65 - NCT03907046RecruitingPhase 3
Blood thinner study to prevent stroke after brain bleed
This Phase 3 study tests whether a blood thinner (apixaban) can help prevent another stroke and support recovery after you’ve had a brain bleed. You would be assigned to a treatment group, and the study checks safety and whether strokes can be reduced without causing dangerous bleeding.
Birmingham, AlabamaAges 18 years+
Common questions
- Are there clinical trials studying Aspirin?
- Yes. Clin2 currently lists 136 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.
