E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |

|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The DEBATER 2 study is a single centre, investigator-initiated, prospective open 2x2 factorial randomized trial with independent data management, independent statistical analysis and blinded endpoint evaluation. The study is designed to determine the non-inferiority of TITANOX over EES and to determine the superiority of bivalirudin during 4 hours over bivalirudin during PCI in patients with ACS who are scheduled for primary PCI (STEMI) or for immediate PCI < 2.5 hours or early PCI < 48 hours (NSTEMI) and who are pre-treated with HLD clopidogrel, and post-treated with DD clopidogrel for 1 week after PCI. |
|
E.2.2 | Secondary objectives of the trial |
The composite of all-cause mortality, any myocardial infarction, bleeding and stroke at 30 days |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Patients who fulfill the inclusion/exclusion criteria but who are not selected or who refuse participation, will be treated according to our current routine, i.e. pre-treatment with 160 mg aspirin and HLD clopidogrel, followed by PCI with either DES or BMS, with or without GPI, with the decisions optional to the discretion of the attending intervention cardiologist. During the DEBATER 2 study a separate parallel registry will be kept of all patients referred to our centre for primary PCI and for immediate PCI or PCI <48 hrs after NSTEMI. - Correlation of ECG and coronary angiography - Fractional flow measurements - Subgroup analysis between the 4 allocations |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary Endpoints (for the comparison of stents): The device-oriented primary endpoint is the composite of cardiac death, myocardial infarction not attributable to a non-target vessel and target lesion revascularization (TLR) at 1 year.
The patient-oriented primary endpoint is the composite of all-cause mortality, any myocardial infarction (including non-target vessel territory), any repeat revascularization (includes all target and non-target vessels).
Primary Endpoints (for Bivalirudin): The device-oriented Primary Endpoint for the comparison of bivalirudin during PCI and bivalirudin during 4 hours and for the comparison of EES and TITANOX is the composite (in hierarchical order) of cardiac death, myocardial infarction not attributable to a non-target vessel and target lesion revascularization (TLR) at 30 days.
The patient-oriented Primary Endpoint for the comparison of bivalirudin during PCI and bivalirudin during 4 hours and for the comparison of EES and TITANOX is the composite (in hierarchical order) of all-cause mortality, any myocardial infarction (including non-target vessel territory), any repeat revascularization (includes all target and non-target vessels) at 30 days.
