Edge Therapeutics Raises $18 Million to Advance Clinical Development of Potentially Life-Saving Hospital Products

NEW PROVIDENCE, NJ--(Jun 4, 2013) -  Edge Therapeutics, Inc., a clinical-stage biopharmaceutical company focused on developing and commercializing life-saving hospital products for acute, fatal or debilitating conditions, announced today that it has raised $18 million in a Series C financing. Maxim Group LLC was the sole placement agent and financial advisor for the offering.

Edge expects to use the proceeds to fund a Phase 2 study of its lead product candidate, EG-1962 (nimodipine microparticles), for the prevention of delayed cerebral ischemia (DCI), a life-threatening complication of subarachnoid hemorrhage (SAH). Results from the first open-label clinical study of EG-1962 are scheduled for oral presentation at Vasospasm 2013, the 12th International Conference on Neurovascular Events after Subarachnoid Hemorrhage, on Fri., July 12, 2013 in Lucerne, Switzerland. Edge also plans to advance EG-1964, its second product candidate, currently in early-stage development for the treatment of chronic subdural hematoma, another potentially lethal type of brain hemorrhage.

"This significant funding fuels ongoing research of potentially life-saving therapies for patients to prevent catastrophic complications of brain hemorrhage," said Brian Leuthner, President and CEO of Edge Therapeutics. "We are gratified by the enthusiastic response of our investors."

Sol J. Barer, Ph.D., Chairman of the Board of Directors for Edge Therapeutics, added: "This significant investment gives Edge the financial resources to grow the Company and further develop its pipeline of life-saving products."

About Delayed Cerebral Ischemia

Delayed cerebral ischemia (DCI) is a delayed life-threatening neurological condition that occurs as a result of subarachnoid hemorrhage (SAH), a neurovascular event that is most commonly caused by a ruptured brain aneurysm (aneurysmal SAH) or a traumatic brain injury (TBI). DCI is a major cause of death and disability in patients who are treated in the hospital for SAH.1,2,3 According to the World Health Organization and the International Brain Injury Association, at least two million people each year suffer conditions that put them at risk for DCI. DCI commonly affects the working population (average age 50 years old) and occurs in approximately one-third of patients during the first two weeks after SAH, often resulting in substantial disability or death.1

About Edge Therapeutics, Inc.

Edge Therapeutics, Inc. is a private, clinical-stage biopharmaceutical company focused on developing and commercializing life-saving hospital products that improve patient outcome by addressing acute, fatal or debilitating conditions after brain hemorrhage that have no current effective treatment. The Company's patent-protected bio-absorbable microparticle formulations release drugs locally and consistently at therapeutic concentrations in the brain, with the objective of maximizing therapeutic activity and avoiding treatment-limiting systemic side effects seen with current treatments. Currently, oral- or IV-administered therapies are employed in suboptimal concentrations due to the generation of systemic side effects. Edge's lead products, EG-1962 (nimodipine microparticles) and EG-1964, are being developed to prevent various delayed complications after brain hemorrhage. EG-1962 is a proprietary microparticle formulation of the generic calcium channel blocker nimodipine, while EG-1964 delivers a hemostatic agent.
