(Nasdaq:EDGE), a clinical-stage biotechnology company developing novel hospital-based therapies in the management of acute, life-threatening conditions, today announced that the full dataset from its North American Phase 1/2 NEWTON (Nimodipine microparticles to Enhance recovery While reducing TOxicity after subarachNoid hemorrhage) study of EG-1962 has been accepted for an oral presentation at the International Stroke Conference 2016 (ISC), to be held February 17-19 at the Los Angeles Convention Center in Los Angeles, Calif. EG-1962, Edge’s lead product candidate, is in development to treat patients who have suffered an aneurysmal subarachnoid hemorrhage (aSAH) resulting from a ruptured brain aneurysm.

Details of the oral presentation are as follows:

Title: 190 – Safety, Tolerability, Pharmacokinetics and Efficacy of Intraventricular Sustained Release Nimodipine (EG-1962) for Subarachnoid Hemorrhage
Session: A29. SAH and Other Neurocritical Management Oral Abstracts
Location: Room 515 B
Date: Friday, February 19

About EG-1962

EG-1962 is a novel polymeric nimodipine microparticle suspended in a diluent of hyaluronic acid that utilizes Edge Therapeutics’ proprietary Precisa^TM development platform designed to improve patient outcomes following an aneurysmal subarachnoid hemorrhage (aSAH). EG-1962 has been granted orphan drug designation by the U.S. Food and Drug Administration (FDA) and the European Commission (EC) for the treatment of patients with aSAH.

About aSAH

An aneurysmal subarachnoid hemorrhage, or aSAH, is a brain hemorrhage after which blood from a ruptured aneurysm enters the subarachnoid space, the area between the middle and deepest protective layers of the brain. Approximately 600,000 individuals worldwide suffer an aSAH annually. In the U.S., approximately 35,000 aSAH patients, with an average age of 52, arrive alive at the hospital each year, and approximately 75 percent of these patients die or suffer permanent brain damage.

About the NEWTON Study

NEWTON was a multicenter, randomized, controlled, open-label Phase 1/2 study evaluating the safety, tolerability and pharmacokinetics of escalating doses of EG-1962 compared to the current standard of care, oral nimodipine, in subjects with an aneurysmal subarachnoid hemorrhage (aSAH). Fifty-four patients were randomized to receive EG-1962 and 18 patients were randomized to receive oral nimodipine. Pooled efficacy results of the NEWTON study showed that 60 percent of patients treated with EG-1962 achieved a favorable outcome (scores of 6-8 as measured by the Extended Glasgow Outcome Score [GOSE]) at 90 days compared to 28 percent of patients in the active control standard of care oral nimodipine arm who achieved a favorable outcome.

About Edge Therapeutics, Inc.

Edge Therapeutics, Inc. 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, Edge’s 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, Edge’s second product candidate, is being evaluated as a potential prophylactic treatment in the management of chronic subdural hematoma, to prevent recurrent bleeding on the surface of the brain.
