Study of blood thinner response after carotid stent
This study looks at how well clopidogrel works in adults who receive a carotid artery stent and are on dual blood thinners. It may help doctors understand why some people don’t get the expected benefit and improve treatment after stenting.
San Donato Milanese, MilanAges 18 years+ - NCT05638867RecruitingPhase 4
Blood thinner choice guided by risk score for heart attack patients
This trial is testing whether a newer type of blood thinner (called a NOAC) can be used safely right after a heart attack or related event, in addition to the standard two antiplatelet medicines. It focuses on patients who have higher risk signs, like elevated D-dimer levels or a higher PARIS risk score, to see if this approach is safe and effective at preventing future heart problems.
Beijing, Beijing MunicipalityAges 18–75 - NCT07265466RecruitingPhase 1
Safety study of JP-1366 with common heart and blood medications
This trial tests how a new drug, JP-1366, interacts with several common heart and blood medications (clopidogrel, aspirin, atorvastatin, and apixaban) in healthy volunteers. It aims to see if the combination is safe and how the drugs affect each other in the body.
Seongnam-si, Gyeonggi-doAges 19–64 - NCT06650488RecruitingPhase 4
Clopidogrel vs. Aspirin for Heart Protection in Blood Infection Patients
This trial tests whether switching from aspirin to clopidogrel better protects your heart and blood vessels during recovery from a serious staph infection in the blood. You may be eligible if you currently take aspirin for heart or stroke prevention.
Montreal, QuebecAges 18 years+ - NCT06692933RecruitingEarly Phase 1
How hemp affects a common blood thinner
This study tests if a hemp product changes how the body processes the blood thinner clopidogrel (Plavix). You must be healthy, have used cannabis before without problems, and have a specific gene type that affects how these substances break down.
Spokane, WashingtonAges 21–64 - NCT06588595RecruitingPhase 4
Switching Blood Thinners After Stent Placement
This study compares two ways to manage blood thinners after a stent. It tests whether switching from stronger drugs (prasugrel or ticagrelor) to clopidogrel is safe and effective for long-term heart protection.
Jacksonville, FloridaAges 18 years+ - NCT04937699RecruitingPhase 4
Switching anti-platelet tablets after a heart stent
This trial studies whether changing the timing and type of blood-thinner tablets after a heart stent is as safe and effective as continuing the same plan. It may help some people by simplifying treatment while preventing dangerous clotting after a coronary procedure.
Hangzhou, ZhejiangAges 18–80 - NCT05320926Recruiting
Clopidogrel vs aspirin after heart stent treatment
This trial compares two blood-thinning medicines—clopidogrel and aspirin—after you have finished a short period of dual therapy following a special type of drug-eluting heart stent. It may help find which medicine works better and is safer for preventing future heart problems.
SeoulAges 19–84 - NCT05493657Recruiting
Aspirin vs clopidogrel after TAVR valve procedure
This trial compares aspirin and clopidogrel (two blood-thinning medicines) after TAVR to see which is safer or more effective for preventing clots. You may be able to join if you recently had a TAVR for severe aortic valve narrowing and can follow the study plan.
SeoulAges 19 years+ - NCT05845489RecruitingPhase 4
Clopidogrel to prevent heart problems from minor artery plaque
This trial tests whether clopidogrel (a blood-thinning medicine) can prevent future heart attacks or strokes in people who have early, “subclinical” plaque in their heart arteries. You may be considered if scans show plaque but not major artery blockage that needs a procedure.
Seoul, OtherAges 40 years+ - NCT05885932Recruiting
Stent treatment versus medicines for blocked neck artery
This study compares a drug-coated stent placed in a neck (vertebral) artery versus best medical treatment with medicines and risk-factor control. It aims to reduce problems caused by a badly narrowed artery after recent stroke-like symptoms.
BeijingAges 18 years+ - NCT05926271RecruitingPhase 2
Genotype-guided clopidogrel alone after stent placement
This trial looks at whether using clopidogrel by itself (without aspirin) works for people after a new drug-eluting stent, based on a blood test of how your body processes the drug. It may help reduce “extra blood-thinning” if you have a certain genetic type that responds well to clopidogrel.
Nieuwegein, UtrechtAges 18 years+ - NCT06228456RecruitingPhase 4
Low-dose ticagrelor vs clopidogrel for stable heart patients after stent
This trial tests whether a lower dose of the blood thinner ticagrelor works better than clopidogrel in people with stable coronary artery disease who are getting a planned stent. It aims to find which drug is safer and more effective for preventing future heart problems.
Jacksonville, FloridaAges 18 years+ - NCT06276374Recruiting
Dual antiplatelet therapy after carotid artery stenting for high bleeding risk
This trial tests if taking two blood thinners (dual antiplatelet therapy) after a carotid artery stenting procedure is safe and effective for patients who have a higher risk of bleeding. It focuses on people with significant blockages in the neck arteries who are also at increased risk for serious bleeding or brain bleeds.
SeoulAges 19 years+ - 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 - NCT06360120RecruitingPhase 3
Clopidogrel plus a statin for large-vessel stroke recovery
This study tests whether adding clopidogrel (a blood thinner) to atorvastatin or rosuvastatin (cholesterol-lowering drugs) helps people who had a first-time large-vessel ischemic stroke. It aims to find the best way to prevent another stroke.
Kafr ash ShaykhAges 18–75 - NCT06402747RecruitingPhase 4
Comparing clopidogrel vs cilostazol for diabetes-related artery thickening
This trial compares two blood-thinning drugs (clopidogrel and cilostazol) to see which one better prevents artery problems in people with diabetes and thickened carotid arteries. It may help you if you have diabetes and are already on stable medications.
Seongnam-si, Gyeonggi-doAges 19 years+ - NCT06591299RecruitingPhase 3
Aspirin plus cilostazol or clopidogrel for minor stroke or TIA
