Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key exclusion criteria
* Patient has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute myocardial infarction (MI)
* Patient has had a known diagnosis of recent MI (within 30 days prior to the index procedure) and has elevated enzymes at the time of the index procedure as follows.

* Patients are excluded if any of the following criteria are met at the time of the index procedure

* If creatine kinase, MB band (CK-MB) >2× upper limit of normal (ULN), the patient is excluded regardless of the creatine kinase (CK) Total.
* If CK-MB is 1-2× ULN, the patient is excluded if the CK Total is >2× ULN.
* If CK Total/CK-MB are not used and Troponin is, the patients are excluded if the following criterion is met at the time of the index procedure.

* Troponin >1× ULN with at least one of the following.

* Patient has ischemic symptoms and electrocardiogram (ECG) changes indicative of ongoing ischemia (e.g., >1mm ST segment elevation or depression in consecutive leads or new left bundle branch block [LBBB]);
* Development of pathological Q-waves in the ECG
* Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality.

Note: For patients who have had a recent MI, CK Total/CK-MB (or Troponin if CK Total/CK-MB are not used) must be documented prior to enrolling the patient

* Non-target vessel or side branch has been treated with any type of PCI (eg, balloon angioplasty, stent, cutting balloon, atherectomy) within 24 hours prior to the index procedure
* Planned or actual target vessel treatment with an unapproved device, directional or rotational coronary atherectomy, laser, cutting balloon or transluminal extraction catheter immediately prior to stent placement
* Planned percutaneous coronary intervention or coronary artery bypass grafting after the index procedure
* Patient previously treated at any time with coronary intravascular brachytherapy
* Patient has a known allergy to the study stent system or protocol-required concomitant medications (e.g., stainless steel, platinum, cobalt, chromium, nickel, tungsten, acrylic, fluoropolymers, everolimus, thienopyridines, aspirin, contrast) that cannot be adequately premedicated
* Patient has active peptic ulcer or active gastrointestinal (GI) bleeding
* Patient has one of the following:

* Other serious medical illness (eg, cancer, congestive heart failure) that may reduce life expectancy to less than 24 months
* Current problems with substance abuse (eg, alcohol, cocaine, heroin, etc.)
* Planned procedure that may cause non-compliance with the protocol or confound data interpretation
* Patient is participating in another investigational drug or device clinical trial that has not reached its primary endpoint
* Patient intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure
* Known intention to procreate within 12 months after the index procedure
* Female with positive pregnancy test within 7 days prior to the index procedure (a pregnancy test must be performed in women of child-bearing potential prior to enrollment), or lactating
* Patient has more than 1 target lesion or more than 1 target lesion and 1 non-target lesion, identified during screening for intervention

Angiographic

* Target lesion meets any of the following criteria:

* Aorto-ostial location (i.e., lesion located within 5 mm of the ostium)
* Left main location
* Located within 5 mm of the origin of the left anterior descending (LAD) coronary artery or left circumflex (LCX) coronary artery
