Edge Therapeutics, Evonik Granted EG-1962 Composition Of Matter Patent

New Patent Protection Extends To At Least 2033

“We are pleased that the U.S. Patent and Trademark Office (USPTO) has issued this composition of matter patent, which builds upon our existing intellectual property portfolio for EG-1962,” said Brian Leuthner, Chief Executive Officer and President of Edge Therapeutics, Inc. “Together with our partners at Evonik, we are developing EG-1962 to improve patient outcomes in this vulnerable patient population.”

Edge is currently conducting the Phase 1/2 NEWTON study, evaluating the safety, tolerability and pharmacokinetics of EG-1962 compared to oral nimodipine, the current standard of care, in patients with aneurysmal subarachnoid hemorrhage. EG-1962 allows delivery of nimodipine directly to the site of injury in the brain through a single administration with a sustained drug exposure for 21 days. Evonik manufactures EG-1962 and other clinical materials at its Birmingham, Ala. site, using its proprietary FormEZE® microparticle technology and Resomer® Select biomaterials.

“We are pleased to partner with Edge Therapeutics for this important project that aims to treat patients suffering from aneurysms and improve their recovery,” said Jean-Luc Herbeaux, Head of Evonik’s Global Health Care Business Line. “Evonik is always excited to embark on new treatments that can revolutionize modern-day medicine. Our global network of experts and research and manufacturing facilities offer a vast array of technologies and competencies that can bring concepts to life and support such ventures.”

About EG-1962
EG-1962 is a novel polymeric nimodipine microparticle that is administered directly into the brain. A single dose of EG-1962, administered initially at the time of aneurysm repair delivers a high concentration of nimodipine directly to the brain, with sustained drug exposure over 21 days. EG-1962 utilizes Edge’s proprietary, programmable, biodegradable polymer-based development platform, known as Precisa™. The Precisa™ platform allows Edge to create therapeutics capable of delivering medicines directly to the site of injury, providing a delivery mechanism that enables targeted and sustained drug exposure while potentially avoiding the systemic, dose-limiting side effects often associated with current standards of care. EG-1962 is currently being evaluated in the Phase 1/2 NEWTON study, a safety, tolerability and pharmacokinetics clinical trial.

About Edge Therapeutics, Inc.
Edge Therapeutics is a clinical-stage biotechnology company that discovers, develops and seeks to commercialize novel, hospital-based therapies capable of transforming treatment paradigms in the management of acute, life-threatening neurological conditions. EG-1962, our lead product candidate, has the potential to fundamentally improve patient outcomes and transform the management of aneurysmal subarachnoid hemorrhage, or aSAH, which is bleeding around the brain due to a ruptured brain aneurysm. EG-1964, our second product candidate, is being evaluated as a potential prophylactic treatment in the management of chronic subdural hematoma (cSDH), to prevent recurrent bleeding on the surface of the brain.
