Merit Medical Highlights Success of WRAPSODY CIE Device
Overview of WRAPSODY CIE Efficacy
Recent studies reveal impressive milestones achieved by the WRAPSODY Cell-Impermeable Endoprosthesis (CIE) in enhancing vascular access for patients undergoing hemodialysis. At six months, this pioneering device demonstrated a target lesion primary patency of 89.8% and access circuit primary patency of 72.6%. The twelve-month outcomes continued to reflect its efficacy with figures reaching 70.1% for target lesion primary patency and 58.1% for access circuit primary patency.
Significant Trial Results
Merit Medical Systems, Inc. (NASDAQ: MMSI) recently shared these compelling results, originally from the randomized arm of the WRAPSODY Arteriovenous Access Efficacy (WAVE) trial. The six-month outcomes are set to be detailed in the upcoming April issue of Kidney International. Meanwhile, the twelve-month findings will be presented at the Society of Interventional Radiology’s annual scientific meeting, a platform for vital clinical discussions and innovations.
Importance for Hemodialysis Patients
The creation of an arteriovenous fistula (AVF) is essential for patients requiring hemodialysis, as it provides long-term access to blood vessels. However, stenosis, or narrowing of the blood vessels around the AVF, often poses significant challenges to treatment. The WRAPSODY CIE is meticulously designed to combat these obstacles and restore vascular access effectively.
Details of the WAVE Trial
The WAVE trial is an international and multicenter investigational device exemption (IDE) study that assesses the safety and efficacy of the WRAPSODY CIE over a two-year period. In this trial, 245 hemodialysis patients with venous outflow stenosis were treated with either the WRAPSODY CIE or the conventional percutaneous transluminal angioplasty (PTA). This thorough comparison sheds light on the potential benefits of the advanced device.
Defining Efficacy and Safety
Efficacy in the context of this trial focuses on the percentage of patients who did not require further interventions due to clinically driven target lesion revascularization or thrombosis. Another important measure is the proportion of patients who maintained vascular access within their circuit without needing reintervention.
On the safety side, the study monitored occurrences that negatively impacted vascular access or venous outflow, specifically avoiding complications associated with target lesion revascularization or thrombosis.
Impressive Efficacy Findings
The initial results at the six-month mark showed a striking difference between the WRAPSODY CIE and the PTA. The WRAPSODY CIE achieved a target lesion primary patency of 89.8%, significantly higher than the 62.8% seen with PTA. Likewise, the access circuit primary patency was recorded at 72.6% for WRAPSODY compared to 57.9% for PTA. These outcomes underscore the potential of the WRAPSODY CIE in improving patient care.
Expert Testimonials
Dr. Dheeraj K. Rajan, a key investigator associated with the WAVE trial, emphasized the importance of the one-year durability of the device, stating, "The WRAPSODY CIE’s positive outcomes at one year address an important knowledge gap regarding the potential durability of the device.” His insights highlight the potential this device has in extending functional vascular access for patients.
Commitment to Patient Care
Merit Medical, under the leadership of CEO Fred P. Lampropoulos, is dedicated to advancing healthcare technology. He remarked, “We are committed to improving patient care and providing clinicians with the data they need to make evidence-based decisions.” This ongoing commitment to innovation positions the company as a frontrunner in the medical device sector.
Regulatory Approvals and Market Presence
In December 2024, the WRAPSODY CIE received premarket approval from the U.S. Food and Drug Administration (FDA), paving the path for its commercial use. By January 2025, the device was available for use in the U.S. market. Additionally, it has been granted the Conformité Européenne (CE) Mark, affirming its availability across the European Union, and it is also accessible in Brazil.
