Edge Therapeutics Receives Pediatric Investigation Plan Waiver from the European Medicines Agency

BERKELEY HEIGHTS, N.J., June 08, 2017 -- Edge Therapeutics, Inc. (Nasdaq:EDGE), a clinical-stage biotechnology company developing novel hospital-based therapies in the management of acute, life-threatening conditions, today announced that it received a product-specific pediatric waiver from the European Medicines Agency (EMA) for EG-1962, Edge's lead product candidate, which is currently in Phase 3 clinical development for the treatment of aneurysmal subarachnoid hemorrhage (aSAH). The European pediatric waiver for EG-1962 applies to all subsets of the pediatric population.

“This waiver represents an important milestone in the regulatory process in Europe, and will allow Edge to submit a marketing authorization application for EG-1962 to the EMA following completion of the Phase 3 NEWTON 2 study, without the requirement to conduct clinical studies in a pediatric population either pre-approval or post-approval,” said Brian A. Leuthner, Edge’s President and Chief Executive Officer.

As part of the regulatory process for the registration of new medicines with the EMA, pharmaceutical companies are required to provide a Pediatric Investigation Plan (PIP) that outlines the clinical development strategy for studying the investigational product in the pediatric population. In some instances, a waiver from developing a PIP for certain conditions may be granted by the EMA when development of a medicine for use in children is not feasible or appropriate.

EG-1962 has been granted orphan drug designation and Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with subarachnoid hemorrhage (SAH). The European Commission has granted orphan drug designation to EG-1962 for treatment of aSAH. In the U.S., products with indications having an orphan designation, such as EG-1962 in SAH, are exempt from requirements to assess the safety and effectiveness for the claimed indication in a pediatric population to support a new drug application submission.
