BIOFREEDOM Stent Versus ORSIRO Stent: SORT OUT IX

Randomized Comparison of a Polymer-Free Biolimus-eluting BIOFREEDOM Stent With a Biodegradable-Polymer Sirolimus-eluting ORSIRO Stent in Patients Treated With Percutaneous Coronary Intervention

The aim of the Danish Organization for Randomized Trials with Clinical Outcome (SORT OUT) is to compare the safety and efficacy of the polymer-free Biolimus-eluting BIOFREEDOM stent with a biodegradable-polymer Sirolimus-eluting ORSIRO stent in a population-based setting, using registry detection of clinically driven events

SORT OUT IX is a randomized, multicenter, all-comer, two-arm, non-inferiority trial comparing the polymer-free Biolimus-eluting BIOFREEDOM stent with a biodegradable-polymer Sirolimus-eluting ORSIRO stent in treating atherosclerotic coronary artery lesions.

Patients will be enrolled by the investigators and randomly allocated to treatment groups after diagnostic coronary angiography and before percutaneous coronary intervention. Block randomization by centre (permuted blocks of random sizes (2/4/6)) will be used to assign patients in a 1:1 ratio to receive the polymer-free Biolimus-eluting BIOFREEDOM stent (Biosensors) or the biodegradable-polymer Sirolimus-eluting ORSIRO stent (Biotronik). A web based Trial Partner randomization system will be used.

Inclusion Criteria:

• Patients aged 18 years or over with chronic stable coronary artery disease or acute coronary syndromes, and at least one coronary artery lesion with more than 50% diameter stenosis, requiring treatment with a drug-eluting stent.

Exclusion Criteria:

• Life expectancy of less than one year; an allergy to aspirin, clopidogrel, ticagrelor, prasugral, biolimus or sirolimus; participation in another randomized trial; or inability to provide written informed consent.
