Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All potential participants will be screened for general eligibility criteria following informed consent. Screening procedures will include baseline coronary angiography to assess if the target lesion and vessel meet eligibility criteria. Randomization will be handled either via phone call or web access to a central automated randomization service using which will provide treatment assignment. Investigators treating enrolled subjects will not be blinded to treatment assignment to ensure safe and proper use of both the control and investigational device. The subject will be blinded to treatment assignment unless for unforseen reasons, in the interest of the subject's safety, it is determined that unblinding is required to protect the individual.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be conducted using a centralized randomization service. Randomization will be done on a 1:1 basis within each site. The randomization schedule was constructed using a random permuted block scheme stratified by site and diabetic status within the site randomization block.
