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.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Everolimus-Eluting Coronary Stent System (PROMUS Element) is a metal tube coated with the drug Everolimus. A single stent will be permanently implanted in the patient via use of a catheter inserted into the vasculature. The drug dosage depends on the size of the stent and varies from 57 micrograms (2.25x12mm stent) to 242 micrograms (4.0x38mm stent) and this drug is gradually eluted into the blood stream following implantation of the stent. Stent size is selected by the investigator based on vessel diameter and length. Typically stent diameter is selected to be slightly larger than the vessel diameter (ie a 3.0mm stent would be used to treat a 2.8mm vessel). Typically stent length is selected so that the stent is 2-4mm longer than the lesion length (ie a 28mm stent would be used to treat a 22mm lesion)

Outcomes
Primary outcome [1] 5009 0
Cardiac events at 30 days post index procedure: Myocardial Infarction, Cardiac Death Rate, Target Lesion Failure (TLF)Rate, Target Lesion Revascularisation (TLR) rate & Stent Thrombosis (ST) rate
Timepoint [1] 5009 0
Cardiac events will be assessed during hospitalization and at the 30 day follow up. Any adverse event experienced prior to the 30 day follow up must be reported within 24 hours. Source data regarding the event will be collected and sent to the Clinical Events Commottee (CEC) for adjudication.
Secondary outcome [1] 8456 0
Target vessel failure (TVF) is any ischemia-driven revascularization of the target vessel, Myocardial Infarction (MI) (Q-wave and non Q-wave) related to the target vessel or death related to the target vessel. If it cannot be determined with certainty whether the MI or death was related to the target vessel, it will be considered a TVF. Any of the component events (TVR, MI or death) must be reported to the sponsor within 24 hours. Source data regarding the event will be collected and sent to the Clinical Events Committee (CEC) for adjudication.
Timepoint [1] 8456 0
30 days, 9 months & 12 months post index procedure
Secondary outcome [2] 8457 0
Target vessel revascularization (TVR) is defined as a Target Lesion Revascularisation (TLR) or a TVR remote. Target lesion revascularization is any ischemia-driven repeat percutaneous intervention, to improve blood flow, of the successfully treated target lesion or bypass surgery of the target vessel with a graft distally to the successfully treated target lesion. A TLR will be considered as ischemia-driven if the target lesion diameter stenosis is 50% by QCA and there is presence of clinical or functional ischemia which cannot be explained by other coronary or graft lesions. Clinical or functional ischemia is any of the following:
* The patient has a positive functional study corresponding to the area served by the target lesion
* The patient has ischemic electrocardiogram (ECG) changes at rest in a distribution consistent with the target vessel
* The patient has ischemic symptoms referable to the target lesion
A TLR will be considered as ischemia-driven if the lesion diameter stenosis is 70% by QCA even in the absence of clinical or functional ischemia
Target vessel revascularization remote is any ischemia-driven repeat percutaneous intervention, to improve blood flow, or bypass surgery of not previously existing lesions diameter stenosis 50% by QCA in the target vessel, excluding the target lesion. A TVR will be considered ischemia-driven if the target vessel diameter stenosis is 50% by QCA and any of the following are present:

* The patient has a positive functional study corresponding to the area served by the target lesion

* The patient has ischemic ECG changes at rest in a distribution consistent with the target vessel
* The patient has ischemic symptoms referable to the target lesion
A TVR will be considered as ischemia-driven if the lesion diameter stenosis is 70% by QCA even in the absence of clinical or functional ischemia.

Any events must be reported to the sponsor within 24 hours. Source data regarding the event will be collected and sent to the Clinical Events Committee (CEC) for adjudication.
