Dual therapy with a P2Y12 receptor antagonist in addition to aspirin is the antiplatelet treatment of choice in patients with acute coronary syndromes or undergoing percutaneous coronary intervention (PCI). However, available oral P2Y12 antagonists have several limitations, mostly due to their pharmacological profile, which can affect outcomes in certain clinical settings. Cangrelor is an intravenous, direct-acting, potent P2Y12 inhibitor with rapid onset and offset of action, which has been recently approved for clinical use in patients undergoing PCI...

Thrombotic events such as myocardial infarction or stent thrombosis are the major cause of adverse outcomes in patients undergoing percutaneous coronary intervention (PCI). While current antiplatelet agents, anticoagulants, and PCI techniques have reduced the risk of thrombotic events in PCI-treated patients, a considerable hazard still remains. Cangrelor is an intravenous P2Y12 receptor antagonist that provides a rapid onset and maximal platelet inhibition, which is quickly reversible. In the large-scale CHAMPION PHOENIX trial, cangrelor was shown to reduce ischemic events significantly, including myocardial infarction and stent thrombosis, without increasing the risk of severe bleeding across the full spectrum of patients undergoing PCI, with substantial benefits in all patient subgroups examined...

Ticagrelor is an antagonist of the platelet P2Y12 receptor for ADP, approved for the prevention of thromboembolic events in patients with acute coronary syndrome. Previous studies showed that ticagrelor has no significant activity versus P1 receptors for adenosine and other known P2Y receptors, with the exception of P2Y13, which was not tested. The P2Y12 antagonist cangrelor has been shown to also inhibit P2Y13 and to decrease the P2Y13-regulated capacity of megakaryocytes to produce pro-platelets. We tested whether or not ticagrelor inhibits P2Y13 signalling and function...

Oligodendrocyte precursor cells (OPCs, also called NG2 cells) are scattered throughout brain parenchyma, where they function as a reservoir to replace lost or damaged oligodendrocytes, the myelin-forming cells. The hypothesis that, under some circumstances, OPCs can actually behave as multipotent cells, thus generating astrocytes and neurons as well, has arisen from some in vitro and in vivo evidence, but the molecular pathways controlling this alternative fate of OPCs are not fully understood. Their identification would open new opportunities for neuronal replace strategies, by fostering the intrinsic ability of the brain to regenerate...

AIMS: The purpose of this study was to test whether different results between Cangrelor versus standard therapy to acHieve optimal Management of Platelet InhibitiON (CHAMPION) PCI/PLATFORM and PHOENIX trials are due in part to different definitions of percutaneous coronary intervention (PCI)-related myocardial infarction (MI). METHODS AND RESULTS: In patients with acute coronary syndrome (ACS), the definition of MI was identical in CHAMPION PCI and PLATFORM and did not require an assessment of baseline cardiac biomarker status, while in PHOENIX specific MI criteria were associated with different patient presentations...

This article reviews the pharmacology, clinical efficacy, and safety of vorapaxar in reducing cardiovascular risk. Vorapaxar is a tricyclic himbacine-derived reversible inhibitor of platelet surface protease activator receptor-1, which prevents thrombin from activating platelets. Two Phase III clinical trials and multiple subanalyses from the two trials with vorapaxar have been published. In patients with recent acute coronary syndrome, vorapaxar, when added to standard therapy, did not reduce the composite cardiovascular end point...

BACKGROUND: The Cangrelor Versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition (CHAMPION) PHOENIX trial demonstrated superiority of cangrelor in reducing ischemic events at 48 hours in patients undergoing percutaneous coronary intervention compared with clopidogrel. METHODS AND RESULTS: We analyzed all patients included in the modified intention-to-treat analysis in US (n=4097; 37.4%) and non-US subgroups (n=6845; 62.6%). The US cohort was older, had a higher burden of cardiovascular risk factors, and had more frequently undergone prior cardiovascular procedures...

BACKGROUND: Acetylsalicylic acid and clopidogrel are two antiplatelet agents currently used in the therapy of peripheral arterial disease. Cilostazol also inhibits platelet aggegration. These agents present limitations that novel antiplatelet agents may overcome. OBJECTIVE: The aim of this manuscript is to review current data on the use of novel antiplatelet agents in peripheral arterial disease. METHOD: An extensive search in the English medical literature has yielded a number of publications on a number of novel antiplatelet agents; atopaxar, vorapaxar, cangrelor, ticagrelor, elinogrel, and prasugrel...

The combination of aspirin and a P2Y12 receptor inhibitor is the cornerstone of treatment in patients with acute coronary syndromes (ACSs) and in those undergoing percutaneous coronary intervention (PCI). At the present time, 3 different oral P2Y12 receptor inhibitors are available on the market; 2 have obtained the indication for ACS (clopidogrel and ticagrelor) and 1 for ACS with planned PCI (prasugrel). An intravenous direct acting P2Y12 inhibitor, cangrelor, has also been recently approved by US and European regulatory agencies for patients undergoing PCI...

Oral ADP-receptor antagonists combined with aspirin are the standard for dual antiplatelet therapy (DAPT) during percutaneous coronary intervention (PCI). However, the oral route of administration of ADP-receptor antagonists leaves them vulnerable to unpredictable and often inadequate platelet inhibition at the time of PCI, while their prolonged effects often lead to the decision not to load them prior to PCI. Intravenous antiplatelet agents, including glycoprotein IIb/IIIa inhibitors (GPI) and cangrelor, a reversible P2Y12 inhibitor, address these shortcomings...

Antiplatelet therapy is the cornerstone of the therapeutic arsenal in coronary artery disease. Thanks to a better understanding in physiology, pharmacology and pharmacogenomics huge progress were made in the field of platelet reactivity inhibition thus allowing the expansion of percutaneous coronary intervention. Stent implantation requires the combination of two antiplatelet agents acting in a synergistic way. Asprin inhibit the cyclo-oxygenase pathway of platelet activation while clopidogrel is a P2Y12 adenosine diphosphate (ADP)-receptor antagonist...

BACKGROUND: The optimal anticoagulant for patients with acute coronary syndrome treated with percutaneous coronary intervention (PCI) has not been validated in current practice of radial approach and pretreatment with potent P2Y12 inhibitors. Several studies have indicated increased bleeding rate and, in some instances, even increased mortality by the routine use of heparin and glycoprotein IIb/IIIa inhibitors compared to bivalirudin. Direct comparison of bivalirudin versus heparin alone has yielded contradictory results depending on study designs...
