Merck, known as MSD outside the United States and Canada, announced two regulatory milestones for the company’s investigational vaccine for Ebola Zaire, V920 (rVSV∆G-ZEBOV-GP, live attenuated): the U.S. Food and Drug Administration (FDA) has granted the vaccine candidate Breakthrough Therapy Designation, and the European Medicines Agency (EMA) has granted PRIME (PRIority MEdicines) status.
PRIME is an approach from the European Medicines Agency (EMA) to enhance support for the development of medicines that target an unmet medical need. PRIME is intended to optimize development plans and speed up assessment of the medicine’s application so these medicines may potentially reach patients earlier. PRIME focuses on medicines that may offer a major therapeutic advantage over existing treatments, or benefit patients without treatment options. These medicines are considered priority medicines by EMA. To be accepted for PRIME, a medicine has to show its potential to benefit patients with unmet medical needs based on early clinical data.
“The granting of Breakthrough Therapy Designation by the FDA and PRIME status by the EMA will enable us to continue to accelerate development of V920, and we greatly appreciate the collaboration of these agencies in moving this vaccine candidate forward in potentially meeting this public health need,” said Paula Annunziato, M.D., vice president for clinical research, Merck Research Laboratories.
V920 was initially engineered by scientists from the Public Health Agency of Canada’s National Microbiology Laboratory and subsequently licensed to a subsidiary of NewLink Genetics Corporation. In late 2014, when the peak of the Ebola outbreak in western Africa was at its worst, Merck licensed V920 from NewLink Genetics, with the goal of accelerating the development, licensure, and availability of this candidate vaccine. Since that time, Merck has worked closely with NewLink Genetics and a number of external collaborators to enable a broad clinical development program with funding from the U.S. Government including the Department of Health and Human Service’s Biomedical Advanced Research Development Authority (BARDA) and the Department of Defense’s Defense Threat Reduction Program/Joint Vaccination Acquisition Program (DTRA/JVAP) among others. Additional research evaluating V920 is ongoing.
