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.

Alsym Energy Announces Na-Series Battery Success Developed With Physics-Informed AI Platform27.4.2026 22:25:00 EEST | Press release
Alsym Energy, a pioneer in non-flammable, high-performance sodium-ion batteries, today announced details of the proprietary physics-informed AI platform used to develop the company’s recently launched Na-Series sodium-ion batteries. By integrating fundamental physics models with AI, autonomous testing and proprietary molecular diagnostics in a closed-loop system, Alsym is accelerating the design of safer, inexpensive, commercialized batteries through all phases of the development cycle. As global demand for electricity surges, the limitations of lithium-ion batteries have become increasingly apparent, particularly around safety and supply chain constraints. Lithium-ion chemistry presents inherent challenges, including flammability and reliance on constrained global supply chains—issues that become more acute in large-scale energy storage, where higher energy densities considerably increase fire risks, and growing demand across sectors further strains the supply chain and imperils energ
