Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Aspirin
Treatment: Drugs - P2Y12 inhibitor

Other: Abbreviated antiplatelet regimen - Dual antiplatelet therapy is discontinued immediately after randomization (i.e. 1 month post stent implantation), and a single antiplatelet agent is continued until at least 11 months post randomization (i.e. 12 months post stent implantation).
In patients on oral anticoagulants, dual antiplatelet therapy is discontinued immediately after randomization (i.e. 1 month post stent implantation), and either Aspirin or Clopidogrel is continued until 5 months post randomization (i.e. 6 months post stent implantation). Oral anticoagulation is continued until at least 11 months post randomization (i.e. 12 months post stent implantation)

Other: Prolonged antiplatelet regimen - Aspirin is continued for at least 11 months post randomization (i.e. 12 months post stent implantation), the P2Y12 inhibitor being taken at the time of randomization is continued for at least 5 months and up to 11 months post randomization (i.e. 12 months post stent implantation).
In patients on oral anticoagulants, aspirin and Clopidogrel are continued for at least 2 months post randomization (i.e. 3 months post stent implantation) and up to 11 months post randomization (i.e. 12 months after stent implantation). Either aspirin or Clopidogrel is continued up to 11 months post randomization (i.e. 12 months post stent implantation)

Eligibility
Key inclusion criteria
After index PCI, patients aged 18 years or more are eligible for inclusion into the study
if the following criteria are met.

1. At least one among the HBR criteria (as defined below) is met.

2. All lesions are successfully treated with Ultimaster stent in the context of routine
clinical care, i.e. post-procedural angiographic diameter stenosis <20% by visual
estimation

3. Free from any flow-limiting angiographic complications (i.e. significant untreated
dissection or major side-branch occlusion), which require prolonged DAPT duration
based on operator's opinion.

4. All stages of PCI are complete (if any) and no further PCI is planned.

At randomization visit (one month after index PCI), the following criteria must be met:

1. Fulfilment of at least one HBR criterion (as defined below), or on the basis of
post-PCI actionable (i.e. requiring medical attention) non-access site related
bleeding episode

2. Uneventful 30-day clinical course, i.e. free from spontaneous MI, symptomatic
restenosis, stent thrombosis, stroke and any revascularization (coronary and
non-coronary) requiring prolonged DAPT

3. If not on OAC,

1. Patient is on a DAPT regimen of aspirin and a P2Y12 inhibitor

2. Patient with one type of P2Y12 inhibitor for at least 7 days (i.e. no switching
between oral P2Y12 inhibitors has occurred in the previous 7 days)

4. If on OAC

1. Patient is on the same type of OAC (e.g. Vitamin K antagonist or NOAC) for at
least 7 days

2. Patient is on clopidogrel for at least 7 days

Definition of HBR

Post-PCI patients are at HBR if at least one of the following criteria applies:

- Clinical indication for treatment with oral anticoagulants (OAC) for at least 12
months

- Recent (<12 months) non-access site bleeding episode(s), which required medical
attention (i.e. actionable bleeding).

- Previous bleeding episode(s) which required hospitalization if the underlying cause
has not been definitively treated (i.e. surgical removal of the bleeding source)

- Age equal or greater than 75 years

- Systemic conditions associated with an increased bleeding risk (e.g. haematological
disorders, including a history of or current thrombocytopaenia defined as a platelet
count <100,000/mm3 (<100 x 109/L), or any known coagulation disorder associated with
increased bleeding risk.

- Documented anaemia defined as repeated haemoglobin levels <11 g/dl or transfusion
within 4 weeks before randomization.

- Need for chronic treatment with steroids or non-steroidal anti-inflammatory drugs

- Diagnosed malignancy (other than skin) considered at high bleeding risk including
gastro-intestinal, genito-urethral/renal and pulmonary.

- Stroke at any time or TIA in the previous 6 months

- PRECISE DAPT score of 25 or greater

Summary
Brief summary
The study compares two lengths of medication therapy (a shortened versus a prolonged dual
antiplatelet therapy) in order to prevent thrombus (blood cloth) formation after the
successfully treatment for coronary heart disease with a drug covered stent (metallic tube).

This comparison will be done in patients who, compared to the average patient, are more
likely to suffer from complications on antiplatelet therapy (bleeding). Both durations are
within the current medical recommendations. The aim of this study is to help improve further
standard antiplatelet duration guidelines.
