Filter by:This study will involve healthy volunteers and patients with Type 2 diabetes. Eligible healthy volunteers will be invited to enroll into one of two protocols (A or B) and eligible patients with diabetes will be enrolled into protocol A.
The study is an investigator-sponsored, retrospective cohort study designed to compare efficacy and safety of ticagrelor in elderly patients undergoing percutaneous coronary intervention.
ASA inhalation powder is an inhaled nonsteroidal anti-inflammatory drug-device combination that has been developed to reduce the risk of vascular mortality in patients with suspected acute myocardial infarction (MI), an FDA approved indication for oral formulations of aspirin. The primary goal of study OTP-P0-926 is to collect pharmacokinetic (PK)and pharmacodynamics (PD) pilot data to determine onset and extent of aspirin response after administration of varying doses of inhaled ASA (50-100mg) and 162 mg Non-Enteric-Coated Chewable ASA. PD will be assessed using standard methods to measure platelet inhibition by aspirin including platelet aggregation, serum thromboxane,and urinary thromboxane. Furthermore, the pharmacokinetics (PK) of ASA will be determined and compared to PD measurements. Results of this pilot study will guide dosing in a subsequent larger Phase II study.
A nationwide retrospective cohort study. To investigate the real world medication compliance and the relation with clinical outcomes. The persistence and compliance to dual anti-platelet therapy(DAPT) and dyslipidemia agents are important for the patients undergoing percutaneous coronary intervention. But, the discontinuation and compliance rate are unknown in the real world setting.
This is a multi-center, randomized, double-blind, triple-dummy, parallel-controled, dose-exploration phase II trial. Patients with coronary atherosclerotic heart disease and planned percutaneous coronary intervention （PCI） will be randomized after informed consent, in a 1:1:1:1 ratio to the following treatment groups: Experimental group 1 : Vicagrel 20mg loading followed by 5mg/day for 28 days; Experimental group 2 : Vicagrel 24mg loading followed by 6mg/day for 28 days; Experimental group 3 : Vicagrel 30mg loading followed by 7.5mg/day for 28 days; Control group : Clopidogrel 300mg loading followed by 75mg/day for 28 days. The primary purpose of this trial is to evaluate the efficacy, safety of vicagrel antiplatelet therapy and explore dose in patients with coronary atherosclerotic heart disease during and after PCI compared with clopidogrel.
The GLOBAL LEADERS Adjudication Sub-StudY, GLASSY, is based on a re-assessment of all the events reported in the dataset of the parent trial (COMPARATIVE EFFECTIVENESS OF 1 MONTH OF TICAGRELOR PLUS ASPIRIN FOLLOWED BY TICAGRELOR MONOTHERAPY VERSUS A CURRENT-DAY INTENSIVE DUAL ANTIPLATELET THERAPY IN ALL-COMERS PATIENTS UNDERGOING PERCUTANEOUS CORONARY INTERVENTION WITH BIVALIRUDIN AND BIOMATRIX FAMILY DRUG-ELUTING STENT USE) by an independent Clinical Event Committee (CEC), composed of three physicians not involved in the main trial. The substudy include the first 19 top-enrolling sites of the GLOBAL LEADERS to reach the estimated sample size of 7,186 patients for the two co-primary outcomes of death, any non-fatal myocardial infarction, any non-fatal stroke or urgent target vessel revascularization and bleeding events classified as 3 or 5 according to the Bleeding Academic Research Consortium (BARC) criteria. To ensure a comprehensive assessment of clinical events, a triggers logic is adopted to identify other potential events qualifying for study endpoints but not reported as such by local investigators.
This study evaluates the efficacy of Prasugrel and Ticagrelor in the treatment of acute myocardial infarction.
Background: Clopidogrel, an antiplatelet prodrug, is widely used for prevention of the recurrent cardiovascular events. CYP2C19 is one of the crucial enzymes for the activation of clopidogrel. Recent studies, mostly done in cardiovascular patients, showed association of the CYP2C19 genotypes with recurrent cardiovascular events. However, prospective data on the impact of the genetic variants in stroke patients are limited. Methods: Five hundred and eighteen Japanese non-acute stroke patients treated with clopidogrel were registered at 14 institutions. Three CYP2C19 variants (CYP2C19*2, *3, *17) were genotyped and the patients were classified into three clopidogrel metabolizer groups inferred from the CYP2C19 genotypes: extensive (EM: *1/*1), intermediate (IM: *1/*2 or *1/*3), and poor (PM: *2/*2, *2/*3, or *3/*3). The CYP2C19*17 carriers were excluded from the analysis. The antiplatelet effects of clopidogrel were assessed by Adenosine diphosphate (ADP) -induced platelet aggregation and vasodilator-stimulated phosphoprotein (VASP) phosphorylation, expressed as VASP index. The endpoint was the composite incidence of stroke, transient ischemic attack, myocardial infarction, revascularization, other thromboembolic disease, or cardiovascular death during 2 years of follow-up.
A single-center, randomized trial of admitted patients with ischemic heart disease receiving percutaneous coronary intervention and stent implantation will be conducted at University Hospital of Ferrara. Patients will be randomized to either the control (standard care) or the bundle group in which patients will receive counseling regarding dual antiplatelet therapy management, advantages and side effects, screening for depression or anxiety, standardized education. The primary endpoint will be the difference in the quality of life as assessed by EQ-5D questionnaire.
The purpose of this study is to determine whether adjunctive cilostazol loading/maintenance to standard treatment (aspirin, clopidogrel, and statin) is effective in reduction of major adverse cardiovascular events, platelet activation, inflammation and myonecrosis in patients with non-ST-elevation acute coronary syndrome (ACS)undergoing percutaneous coronary intervention (PCI).
