IndObufen Versus asPirin After Coronary Drug-eluting Stent implantaTION in Elderly Patients With Acute Coronary Syndrome
Summary: The OPTION2 trial (randomized controlled trial of IndObufen versus asPirin after coronary drug-eluting stent implantaTION in elderly patients with acute coronary syndrome) was designed to compare the 1-year clinical efficacy and safety of indobufen-based dual antiplatelet therapy (DAPT) (indobufen 100mg bid plus ticagrelor 90mg bid) or conventional DAPT (aspirin 100mg qd plus ticagrelor 90mg bid) ...
Evaluation of an asPirin-free Strategy With ticAgrelor in patieNTs witH a Myocardial Infarction treatEd Medically alONe (PANTHEON)
Summary: In patients with a myocardial infarction (MI) treated medically alone, the objective of the PANTHEON trial is to evaluate if ticagrelor monotherapy reduces bleeding events, without an increase in patient-oriented ischemic events, compared with standard dual antiplatelet therapy (DAPT) with aspirin and ticagrelor for 12 months.
Tailoring Bleeding Reduction Approaches in Patients Undergoing Percutaneous Coronary Interventions: Comparative Pharmacodynamic Effects of Potent P2Y12 Inhibitor Monotherapy Versus Dual Antiplatelet Therapy De-escalation
Summary: Two strategies have both proven to be effective in reducing bleeding complications while preserving efficacy compared with maintaining long-term DAPT with aspirin and a potent P2Y12 inhibitor: a) DAPT de-escalation (i.e., switching from prasugrel or ticagrelor to clopidogrel while maintaining aspirin) and b) potent P2Y12 inhibitor monotherapy (i.e., maintaining prasugrel or ticagrelor and dropping...
Comparison of ABCD-GENE Score-Guided Versus Unguided DAPT De-Escalation: A Prospective Randomized Pharmacodynamic Study in Patients Undergoing PCI The Switching Antiplatelet-9 (SWAP-9) Study
Summary: The purpose of this study is to compare the pharmacodynamic effects of ABCD-GENE guided vs. unguided de-escalation strategies among patients on dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI).
Clinical Outcomes of Colchicine Therapy Following Percutaneous Coronary Intervention in Patients With Acute Coronary Syndrome: the MACT (Mono Antiplatelet and Colchicine Therapy) Prospective Multicenter Study
Summary: The previous Mono Antiplatelet and Colchicine Therapy (MACT) pilot study (NCT04949516) demonstrated that it was feasible to discontinue aspirin therapy and administer low-dose colchicine on the day after percutaneous coronary intervention (PCI) in addition to potent P2Y12 inhibitors in patients with acute coronary syndrome (ACS). However, the efficacy and safety of MACT have not yet been investiga...
Switching From Dual Antiplatelet Therapy to Monotherapy With Potent P2Y12 Inhibitors: Pharmadodynamic Comparison Between Prasugrel and Ticagrelor Monotherapy. The Switching Antiplatelet -7 (SWAP-7) Study
Summary: Ticagrelor currently represents the most tested and commonly used P2Y12 inhibitor monotherapy following percutaneous coronary intervention. The purpose of this study is to conduct a head-to-head comparison on the pharmacodynamic efficacy of ticagrelor-based and prasugrel-based single antiplatelet therapy. To determine if the PD profiles of ticagrelor- and prasugrel-based SAPT are comparable, we ai...
Pharmacodynamic Effects of Low-dose Ticagrelor vs. Clopidogrel in Stable Patients Undergoing Elective Percutaneous Coronary Intervention Who Are At Risk of Peri-PCI Myocardial Infarction Using a Precision Medicine Tool
Summary: The proposed study aims to assess the antiplatelet effects of more potent oral P2Y12 inhibition with low-dose ticagrelor (60 mg bid) compared with standard of care clopidogrel in patients with a high ABCD-GENE score (≥10). We hypothesize that ticagrelor is associated with better pharmacodynamic effects (i.e., lower platelet reactivity and high platelet reactivity rates) compared with clopidogrel i...
ST-segment Elevation Myocardial infArction Treated With a Polymer-free Sirolimus-based nanocarrieR Eluting Stent and a P2Y12 Inhibitor-based Aspirin-free Single Antiplatelet Strategy Versus Conventional Dual AntiPlatelet Therapy
Summary: Primary percutaneous coronary intervention (PCI) is the preferred revascularization strategy for patients with acute ST-segment elevation myocardial infarction (STEMI). Compared with bare-metal stents (BMS) and early-generation thick-strut polymer-based drug-eluting stents (DES), newer-generation DES with thinner strut stent platforms and durable or biodegradable polymers have been shown to improv...
International, Multicenter, Investigator-driven Randomized Clinical Trial to Assess the Single vs. Dual Antiplatelet Therapy in Elderly or HBR Patients Undergoing Percutaneous Intervention With Drug-coated Balloons (PICCOLETO IV-EPIC 38)
Summary: This international, multicenter, open-label, randomized clinical trial evaluates the safety and efficacy of single antiplatelet therapy (SAPT) compared to dual antiplatelet therapy (DAPT) in elderly or high bleeding risk patients undergoing percutaneous coronary intervention (PCI) with the latest generation drug-coated balloon (DCB). The study includes patients with stable or unstable coronary syn...
Precision Antiplatelet Therapy Guided by Platelet Aggregation Function in Patients With Acute Ischemic STROKE
Summary: The objective of this clinical trial is to evaluate the efficacy and safety of platelet aggregation function - guided precision anti - platelet therapy in patients with acute cerebral infarction. The main question it aims to answer is: among the cerebral infarction patients with possible clopidogrel resistance detected by platelet aggregation function tests, what is the efficacy and safety of usin...
Anticoagulation for New-Onset Post-Operative Atrial Fibrillation After CABG
Summary: The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery. All patients with a qualifying POAF event, who decline ra...
Assessment of an Early De-Escalation to a Low-potency Single Antiplatelet Therapy Guided by Genetics Versus a Systematic High-Potency Single Antiplatelet Therapy to Neutralize Bleeding Complications in Patients With High Bleeding Risk Beyond One Month After an Acute Coronary Syndrome
Summary: Patients who suffered from acute coronary syndrome (ACS) are usually treated with a long-term dual antiplatelet therapy (DAPT) to reduce stent thrombosis and recurrent ischemic event. Nonetheless, recent important data have demonstrated the efficacy of a short term DAPT and an early single antiplatelet therapy in high bleeding and ischemic risk patients. The bleeding risk is associated with a sign...
