Protembis Announces First Patient Enrolled in the PROTEMBO IDE Pivotal Trial
2.4.2024 08:00:00 EEST | Business Wire | Press release
Protembis GmbH (Protembis), a privately-held emerging cardiovascular medical device company, announced today the enrollment of the first patient in the PROTEMBO Investigational Device Exemption (IDE) Pivotal Trial (NCT05873816). The trial will enroll between 250-500 randomized patients undergoing transcatheter aortic valve replacement (TAVR) in the USA and Europe with the ProtEmbo® System, an innovative next generation cerebral embolic protection device (CEP) providing complete 3-vessel coverage of the cerebral arteries. The PROTEMBO study aims to show superiority of the ProtEmbo® System against a hybrid control group: half receiving no CEP and half receiving the Sentinel™ CEP (Boston Scientific, Marlborough, MA, USA), which covers just two of the three cerebral arteries that originate from the aortic arch. The primary diffusion-weighted magnetic resonance imaging (DW-MRI) efficacy endpoint will use a novel adaptive statistical approach that includes pre-specified interim analyses with the possibility of early study completion in the instance of superiority. The primary safety endpoint is the rate of major adverse cardiac and cerebrovascular events (MACCE) assessed at 30-days.
The trial will be led by Dr Susheel Kodali (New York Presbyterian Hospital, NY, USA), Dr Raj Makkar (Cedars Sinai, Los Angeles, CA, USA) and Dr Stephan Haussig (Herzzentrum, Dresden, Germany), as the designated Global Co-Principal Investigators, with Dr Roxana Mehran (Mount Sinai, NY, USA) as the Chair of the Study Executive Committee.
“The novel adaptive statistical design of this clinical study will answer several important unanswered questions about the role of three-vessel cerebral protection in reducing new lesions in all areas of the brain,” said Dr Mehran. “The results will give the physician community increased confidence in offering patients cerebral protection when they undergo their TAVR procedures.”
“We are proud to be the first center to enroll a patient into this innovative international study,” said Dr Kodali. “The requirement for DW-MRI assessment means that we will be able to accurately quantify the fundamental effect of the technology on reducing the size and frequency of new cerebral lesions, which are very common during the TAVR procedure.”
“We are delighted to announce that the first patient has been enrolled in the trial, and that we are executing a cadenced plan to activate the other investigational sites in the next few months. We would like to express our gratitude to the teams at the sites for the hard work that each has invested in the study startup phase. This significant progress reflects the close collaboration between our study executive committee, our clinical research organization, and core lab partners in planning this complex trial,” said Karl von Mangoldt and Conrad Rasmus Co-CEOs of Protembis.
About ProtEmbo® and Protembis
The ProtEmbo® Cerebral Protection System is an intra-aortic filter device that protects the entire brain from embolic material liberated during TAVR. It is a low-profile non thrombogenic system that shields all cerebral vessels, delivered through the left radial artery for optimal placement and stability. This is an ideal access site enabling physicians to avoid interference with TAVR equipment typically delivered through the femoral artery.
Protembis is a privately held emerging medical device company that has developed the ProtEmbo ® Cerebral Protection System. The company strives to provide a simple and reliable solution to protect patients from brain injury during left-sided heart procedures, improving patient quality of life and reducing overall healthcare costs associated with brain injury during such procedures. The ProtEmbo ® System is currently undergoing clinical investigations.

New CSC Report Illustrates How AI Is Affecting Enterprise Security Leaders16.6.2026 16:00:00 EEST | Press release
CSC, an enterprise-class domain registrar and world leader in mitigating brand, fraud, domain, and domain name system (DNS) threats, today released new research on how chief information security officers (CISOs) are adapting to an evolving artificial intelligence (AI) ecosystem while managing traditional cyber threats, such as DNS outages. According to CSC’s CISO Outlook 2026 report, 73% of respondents say AI presents more of an opportunity than a risk for cybersecurity. However, these security leaders continue to face challenges in addressing attacks, including AI-powered domain generation algorithms (DGAs), which 86% of respondents cite as a threat. To thoroughly understand the CISO perspective on today’s cybersecurity landscape, CSC surveyed 300 senior executives—including CISOs, chief technology officers (CTOs), chief information officers (CIOs), and heads of cybersecurity—in Q1 2026. Key findings from the CISO Outlook 2026 report include: Respondents ranked the top three threats i
Airship Helps DIE ZEIT Turn Silent Advocates into 4.9-Star Rating16.6.2026 16:00:00 EEST | Press release
Airship, the mobile-first customer experience company, today announced that DIE ZEIT, one of Germany’s largest and most prestigious publishers, has successfully transformed its mobile app presence, lifting the Google Play app store rating from 2.7 stars in early 2026 to a near-perfect 4.9 stars. At a time when many traditional publishers are seeing readership numbers plummet, DIE ZEIT is growing — reaching an all-time high circulation in 2025 and building a digital ecosystem around the brand. The majority of the publication’s readers are now digital, but the publication’s app store rating for DIE ZEIT didn’t match this momentum. DIE ZEIT was up against a universal challenge faced by digital product teams and customer experience executives globally: the "silent advocate" problem. While highly satisfied customers rarely pause their reading experience to leave public reviews, users facing temporary, one-off frustrations are highly motivated to voice complaints. This discrepancy often lead
