Who may be able to join

  • 1. Successful PCI with optimal acute stent implantation results (based on local standard of care by angiography and/or findings from intracoronary imaging and on investigators' discretion) of one or more everolimus-eluting SYNERGY® stent(s). Typically, optimal acute coronary stenting result is a combination of successful stent implantation at the target lesion with absence of significant residual diameter stenosis (<20%), no edge dissection, no thrombus, no major side branch occlusion, "no-reflow", no major stent under-expansion or major stent incomplete apposition.

  • patients with at least one stenosis (angiographic, visually determined de novo lesions with ≥50% DS) in at least one major epicardial territory (LAD and/or side branch, CX and/or side branch, RCA and/or side branch) with a vessel size between 2.25 mm and 4.0 mm in diameter supplying viable myocardium without left main stem involvement;
  • Non-acute coronary disease, with normal cardiac troponin values prior to the PCI procedure, and evidences of myocardial ischemia by symptoms or non-invasive testing (e.g. treadmill exercise test, radionuclide scintigraphy, stress echocardiography);

Who cannot join

  • Candidates will be ineligible for enrolment in the study if any of the following conditions apply:
  • Under the age of 18 years or ≥ 75 years;

  • Female who is breastfeeding at time of enrolment;
Show all 14Show fewer

Patients treated with everolimus-eluting SYNERGY® stent(s) but who also concomitantly received any other non-study stent at the same procedure (all lesions must be treated with everolimus-eluting SYNERGY® stent); 11. Patients with planned PCI or surgical intervention to treat any cardiac or non-cardiac condition within the next 6 months; 12. Concomitant cardiac valve disease requiring surgical therapy (reconstruction or replacement); 13. Atrial fibrillation or other indication for oral anticoagulant therapy; 14. Known allergy to aspirin, prasugrel or diagnosed lactose intolerance; 15. Glomerular filtration rate below 60mL/min; 16. Previous stroke or transient ischemic cerebrovascular accident (TIA); 17. Previous history of intracranial haemorrhage or other intracranial pathology associated with increased bleeding risk; 18. Haemoglobin <10 g/dL or other evidence of active bleeding; 19. Peptic ulceration documented by endoscopy within the last 3 months unless healing proven by repeat endoscopy; 20. Any other condition deemed by the investigator to place the patient at excessive risk of bleeding with prasugrel; 21. Participation in another trial with an investigational drug or device; 22. Co-morbidity associated with life expectancy less than 1 year; 23. Assessment that the subject is not likely to comply with the study procedures or have complete follow-up; 24.

About this study

Official title: ASET Clinical Investigational Plan Acetyl Salicylic Elimination Trial: The ASET Pilot Study

A multicenter, single arm, open-label trial of prasugrel monotherapy after PCI with the new-generation thin-strut biodegradable polymer everolimus-eluting SYNERGY® stent in patients with chronic stable angina

Read the detailed description

Single antiplatelet therapy with prasugrel is safe in selected patients undergoing successful PCI with the new generation biodegradable polymer everolimus-eluting SYNERGY® stent.

To assess in a proof-of-concept study the safety of single antiplatelet therapy with prasugrel after PCI with a new generation biodegradable polymer drug eluting stent in terms of ischemic and bleeding outcomes.

The ASET Pilot study is a multicenter, single arm, open-label trial of single antiplatelet therapy with prasugrel for patients undergoing successful and optimal PCI for chronic stable angina with normal cardiac biomarkers values. The patients will be loaded with standard dual antiplatelet therapy according to local practice (usually aspirin 300 mg and clopidogrel 600 mg, unless patient is on long-term therapy) at least 2 hours prior to the diagnostic catheterization or PCI procedure. After PCI, if the results are considered to be satisfactory by the operator based on clinical (e.g. clinical status, ECG, etc.), angiographic and/or findings from intracoronary imaging, only then patients will be enrolled in the study and loaded with prasugrel 60 mg and continued with prasugrel only (10 mg once a day) for three months. Aspirin and clopidogrel will be discontinued. At the 3-months follow-up visit, prasugrel (only) will be replaced by aspirin (only) or dual-antiplatelet therapy according to local standard of care. Clinical follow-up with office visit will be performed at 3 months and telephone contacts at 1, and 4 months (final follow-up). All events will be adjudicated by an independent clinical events committee (CEC).

An independent Data Safety and Monitoring Board (DSMB) will monitor the individual and collective safety of the patients in the study during enrolment phase and up to 3 months follow-up (primary endpoint).

The ASET study is a proof-of-concept pilot, feasibility and safety study designed as a single arm, open label trial with a stopping rule based on the occurrence of definite stent thrombosis. Based on previous pilot studies, 200 patients will be enrolled. The trial will be terminated if more than three (>3) patients experience definite stent thrombosis following index procedure till 4 months follow-up.
