About this study

Official title: The Safety and Clinical Effectiveness of Pipeline™ Flex Embolization Devices With Shield Technology™ in Patients With Intracranial Aneurysms: a Multicentre Retrospective Study of an Australian Cohort (SCOPE-AUS)

This observational, retrospective, single-arm, multi-centre cohort study will use real-world data (RWD) to develop real-world evidence (RWE) of the safety and clinical effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in Australian patients that have received a flow diversion device to treat an intracranial aneurysm (IA). The medical records from 500 procedures completed at Gold Coast University Hospital in Queensland (QLD), Prince of Wales Hospital in New South Wales (NSW), and Sir Charles Gardiner Hospital in Western Australia (WA), will be analysed.

The study will report the risk and likelihood of stroke (ischaemic and haemorrhagic), delayed neurological adverse events and incomplete aneurysm occlusion within sub-groups of the patient cohort and determine the predictive or confounding factors that influence clinical outcomes under pragmatic or 'real-world' conditions.

Read the detailed description

Methodology summary: Single-arm, longitudinal, retrospective, multi-centre cohort study. A collaboration of Australian Interventional Neuroradiologists will create a data bank of existing clinical and angiographic data extracted from medical records review. The data collection variables are pre-specified using grading scales and clinical assessment with the greatest reliability or significant to to accurately represent patient cohorts receiving treatment within all indications of use. The study will establish a minimum dataset to collect patient socio-demographics, aneurysm characteristics, device characteristics, and clinical outcomes for up to 500 procedures completed using Pipeline™ Flex Embolization Device with Shield Technology™. A framework for data ab The prevalence, severity and outcomes of neurological adverse events of interest and bleeding events will be reported . Independent physician assessments of complete aneurysm occlusion from completed computed tomography scans (CT), Magnetic Resonance Imaging (MRI) scans and Digital Subtraction Angiography (DSA) procedures will be determined according to the Raymond Roy Occlusion Classification (MRRC), O'Kelly Marotta scale (OKM) for aneurysm occlusion using flow diverting devices and the Consensus grading scale for endovascular aneurysm occlusion up to 12 months post procedure. Assessments of wall apposition and in-stent stenosis (ISS) will also be completed.

Quality Assurance plan includes - Framework data abstraction - manual of procedures, data dictionary, data abstraction manual, desired inter-rater reliability +0.80; intrarater reliability, intraclass correlation coefficient (ICC) 0.75 - 0.9;

Medical imaging review assessed by assess aneurysm occlusion by an independent interventional neuroradiologist or a local physician operator that did not complete the primary procedure. Physician level of agreement - interrater reliability to be reported;

Independent physician review of all post-op strokes (ischaemic, haemorrhagic) cases to determine aetiology/mechanism;

Study personnel training; Site visits; remote data monitoring, data audits.

Statistical analysis plan include descriptive statistics and regression models to report prevalence, mortality, time-to-event analyses and estimations of risk; Counts of medical records with insufficient data for analysis or where the patient is identified as 'lost follow-up', this will be reported.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pipeline™ Flex Embolization Device with Shield Technology™Device

    Also called Neurointerventional procedure

    Neurointerventional procedures to treat intracranial (cerebral) aneurysms are minimally-invasive procedures performed by Interventional Neuroradiologists. The physician accesses the arterial system through a blood vessel in the groin followed by the insertion of a catheter. Pipeline™ Flex Embolization Device(s) with Shield Technology™,a flow diversion device, is implanted under high-magnification subtraction fluoroscopy, requiring the use of ancillary devices, such as micro-catheters and guidewires to complete the procedure under general anaesthetic. Procedural heparinisation and preloading with dual antiplatelet therapy (DAPT) using acetyl-salicylic acid and P2Y12 inhibitors such as clopidogrel or prasugrel are required.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

Contact Maame Amma P Owusu RN, BSc, MNurSt, NVRN-BC (+61 7 5687 6447, maame.owusu@health.qld.gov.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prevalence of stroke (short-term) (time frame: 30 days). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2019.
