What changed?
The CHALLENGER Registry marks a pivotal step in evaluating the innovative Numen SILK coil embolization system for treating Chronic Subdural Hemorrhage. The registry is designed to collect data on device performance and clinical outcomes under controlled conditions, enabling researchers to deepen their understanding of its procedural efficacy and safety profile for managing cSDH.
What is the Numen SILK device?
The Numen SILK coil embolization system is a medical device designed to perform embolization, a minimally invasive procedure commonly used in neurovascular intervention. The goal with this system, as applied to cSDH, is to embolize specific blood vessels to limit hemorrhaging and potentially reduce complications associated with chronic subdural bleeding. Data from this registry could provide insights into how this device improves clinical outcomes.
What is Chronic Subdural Hemorrhage?
Chronic Subdural Hemorrhage (cSDH) refers to the accumulation of blood between the brain and its outer covering over an extended period. This condition often stems from minor head trauma, age-related changes, or coagulopathy, and it can lead to significant neurological impairment if left untreated.
Who are the sponsors and collaborators?
The primary sponsor of the registry is the Icahn School of Medicine at Mount Sinai, renowned for advancing medical research. Collaboration with MicroPort NeuroTech Co., Ltd., a global leader in neurovascular device manufacturing, further emphasizes the significance of this trial. Both organizations aim to drive innovation and validate the device’s applicability in clinical practice.
Why is this partnership significant?
This collaboration brings together academic research expertise and industry-leading medical device innovation, ensuring robust trial design and execution to meet regulatory and clinical standards.
What is the status of recruitment?
Currently, the CHALLENGER Registry is listed as “Not yet recruiting.” This status indicates that preparatory steps, such as securing study sites and IRB approvals, are still ongoing. The clinical, quality, and regulatory teams should monitor updates closely since recruitment phases will signal the beginning of data collection pivotal to device assessment.
How does recruitment impact the timeline?
Recruitment is fundamental to the study’s execution. Delays in participant enrollment can extend timelines for analyzing findings and submitting regulatory documentation. Tracking updates on ClinicalTrials.gov will provide clarity regarding recruitment milestones.
