CERENOVUS Announces First Patient Enrolled in MEMBRANE Study on Chronic Subdural Hematomas

MEMBRANE study will evaluate TruFill® n-BCA Liquid Embolic System in the embolization of middle meningeal artery as a treatment of chronic subdural hematoma

IRVINE, CA – June 9, 2021 – Johnson & Johnson Medical Devices Companies* today announced the first patient was enrolled in the CERENOVUS-sponsored MEMBRANE study evaluating TruFill® n-BCA Liquid Embolic System in the embolization of middle meningeal artery (MMA) for treatment of chronic subdural hematoma (cSDH) as adjunct to surgical evacuation or as a stand-alone treatment. The randomized study is designed to evaluate the safety and effectiveness of TruFill® n-BCA for the treatment of cSDH, which is still in the investigational stages, and is an important step in the U.S. Food and Drug Administration’s (FDA’s) approval process.

Chronic subdural hematoma (cSDH) is a common neurological disease caused by the accumulation of blood clots on the surface of the brain beneath its outer covering and occurs frequently in older patients who have brain atrophy. As brain tissue shrinks or wastes away, minor head injuries can cause small tearing of blood vessels over the brain surface, leading to blood slowly accumulating over several days or weeks.1 Current trends predict that by 2030, more than 60,000 new cases of cSDH will occur in the United States each year, which will make cSDH the most common neurosurgical condition in adults.2

“As more people in the United States are diagnosed with cSDH, it is critical to explore and understand the potential of MMA embolization to treat this condition safely and effectively,” said Mark Dickinson, Worldwide President, CERENOVUS. “CERENOVUS is committed to developing differentiated solutions to meet physicians’ needs, so they can best support patient populations who face the burden of neurovascular disease.”

The MEMBRANE study will enroll over 300 participants in 35 sites across the United States over the next two years. Participants in the study will be followed for a one-year period. The first patient was enrolled at WVU Rockefeller Neuroscience Institute by Ansaar Rai, M.D. The primary investigators of the study are Dr. Rai, Professor and Chair of Neuroradiology at Rockefeller Neuroscience Institute, West Virginia University School of Medicine in Morgantown, West Virginia and Christopher Kellner, M.D., Assistant Professor in Neurosurgery and Director of the Intracerebral Hemorrhage Program at Mount Sinai Health System, New York.

“The first patient enrollment in the MEMBRANE trial is an exciting milestone for our teams in evaluating MMA embolization as a treatment option for cSDH,” said Dr. Kellner. “We are looking forward to exploring the potential of providing physicians additional ways to address and manage this disease, especially in older adults, who may be more at risk to undergo surgery,” said Dr. Rai.**
