This study compares two approaches after a left atrial appendage closure (LAAC) procedure: taking no blood thinner versus taking just one antiplatelet medication. It aims to see which option is safer for people with atrial fibrillation who are at risk for bleeding.
Nagoya, Aichi-kenAges Any age - NCT06090890RecruitingPhase 4
Anti-inflammatory therapy for repeated stent blockages
This trial tests if anti-inflammatory drugs like prednisone or colchicine can prevent stents from blocking again in people who have already had multiple stent blockages. It may offer a new treatment option for those with recurrent in-stent restenosis.
Beijing, Beijing MunicipalityAges 18 years+ - 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 - NCT07494877Recruiting
Anticoagulant therapy for infertility in women aged 20-45
This study looks at whether blood-thinning medication can improve the chance of pregnancy in women who have trouble conceiving. It focuses on how the medication affects the lining of the womb and its ability to accept an embryo.
Xi'an, ShaanxiAges 20–45 - 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+ - NCT06165068RecruitingPhase 3
Antiplatelet and antioxidant drugs for dry AMD with drusen
This study tests whether antiplatelet drugs (like aspirin) and antioxidants can slow the growth of drusen (yellow deposits) in dry age-related macular degeneration (AMD). It may help prevent the disease from worsening.
Bangkok, DusitAges 50–85 - NCT06414499RecruitingPhase 3
Tenecteplase for mild stroke within 4.5 hours
This trial tests a clot-busting drug called tenecteplase for patients having a mild stroke (with weakness on one side or trouble speaking) who can get treatment within 4.5 hours. The goal is to see if this drug helps improve blood flow and reduces disability.
Beijing, Beijing MunicipalityAges 18 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+ - NCT03255928Recruiting
Study blood clot cell activity in people with a heart pump
This study looks at how your blood’s clot-forming cells (platelets) behave when you have a heart pump device placed (short-term or long-term). The results may help doctors better understand complications and how to manage them after implantation.
Milan, MIAges 18–75 - 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 - 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+ - NCT03957902RecruitingPhase 2
Aspirin blood markers to guide prevention after colon cancer
This Phase 2 trial studies how aspirin affects specific “biomarkers” (measurable body signals) in people newly diagnosed with colon or rectal cancer. The goal is to see whether aspirin-related changes can help design more personalized prevention treatment plans.
Zaragoza, ZaragozaAges 18–79 - 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+ - NCT04694248Recruiting
Blood thinner plus antiplatelet after iliac vein stent
This trial looks at whether taking a blood thinner and an additional clot-prevention medicine (antiplatelet) after iliac vein stenting can improve treatment of certain deep vein clots. It may help prevent the clot from coming back or spreading, but it also increases bleeding risk, so careful eligibility screening is important.
Hangzhou, ZhejiangAges 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+ - 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+ - NCT04847752Recruiting
