An interventional study of Aspirin and P2Y12 inhibitor in High Bleeding Risk, Coronary Artery Disease and PCI, sponsored by ECRI bv. Completed at 138 sites in 30 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-08-20.

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.
The study objective is to determine in a high bleeding risk patient population undergoing PCI under standardized treatment (within current guidelines and instructions for use and including the bioresorbable polymer coated Ultimaster sirolimus-eluting stent), whether abbreviated DAPT is non-inferior to prolonged DAPT regimen in terms of NACE within 12 months, whether abbreviated DAPT is non-inferior to prolonged DAPT regimen in terms of MACCE within 12 months and whether abbreviated DAPT is superior to prolonged DAPT regimen in terms of MCB within 12 months.
There are two treatment strategies:
The study design is an investigator-initiated, randomized, multi-center, clinical trial to be conducted in approximately 100 interventional cardiology centers in across the globe excluding USA. The study includes 2 x 2150 patients (i.e. 4300 patients) Randomization will occur at one month after the PCI procedure. The expected duration of participation for each patient is 14 months.
4,857 studies on the registry are indexed under Coronary Artery Disease; 890 are open to participants now.
This study's enrollment of 4,579 is above the median of 124 across 3,006 interventional studies indexed under Coronary Artery Disease.

After index PCI, patients aged 18 years or more are eligible for inclusion into the study if the following criteria are met.
At randomization visit (one month after index PCI), the following criteria must be met:

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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)

Ran from Apr 2017 to primary completion in Apr 2021, 48 months.
Of 177 industry-sponsored interventional studies with no phase under Coronary Artery Disease, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 40. This study's 48 months is above that.
Counting every sponsor, half of 930 studies reached it within 30 months; a quarter within 15 and three quarters within 50.
