Merck Remains Steadfast in its Commitment to Supporting International Response Efforts to the Ebola Outbreak in the Democratic Republic of the Congo (DRC)


April 9, 2019 5:12 pm ET

KENILWORTH, N.J. April 9, 2019 — Merck (NYSE: MRK), known as MSD outside the United States and Canada, today re-affirmed its commitment to continue to work with the World Health Organization (WHO), Gavi (the Vaccine Alliance), the United States Government and other key stakeholders to provide supply of the investigational V920 Ebola Zaire vaccine as part of international response efforts to the current Ebola outbreak in the Democratic Republic of the Congo (DRC).

Merck recognizes the unique challenges this current outbreak presents, and we commend the Government of the DRC, the WHO and its Regional Office for Africa, Médecins Sans Frontières (MSF) and all involved for their leadership and courage in working tirelessly to stop this dangerous outbreak.

As this outbreak remains a challenge to all concerned, Merck continues to work urgently with our collaborators in three key areas:

  1. Pre-licensure preparedness: supporting outbreak response efforts prior to regulatory licensures by providing the investigational vaccine for use;
  2. Registrations: working rapidly to obtain regulatory licensures and WHO prequalification, including accelerated registrations in African countries at risk for Ebola outbreaks; and
  3. Post-licensure preparedness: if approved, supplying vaccine to support future, more permanent, stockpiles comprised of licensed vaccine.

As of April 8, 2019, Merck has donated and shipped nearly 145,000 doses of investigational vaccine to the WHO, based on requests by the WHO, in support of international response efforts to the outbreaks. At the time of this posting, according to the DRC Ministry of Health, it is estimated that more than 96,000 individuals have now been vaccinated as part of the ongoing response. Merck is working to maintain a stockpile of 300,000 dose-equivalents of investigational vaccine, as we have previously communicated. This stockpile consists of a mixture of the vaccine in bulk form not filled in vials and filled vaccine doses in vials. This stockpile, as with any vaccine stockpile, is inherently dynamic — numbers can change due to shipments, expiry and replenishment. Recognizing that the situation in the DRC is dynamic and that vaccine demand might increase, we are actively working with our collaborators to meet potentially evolving needs, including ongoing replenishment and potential expansion of the current stockpile beyond the doses already made available. Beyond doses already sent, there are approximately 195,000 doses available and ready to be shipped as needed, and Merck is expecting an estimated 100,000 additional doses to be available for shipment within the next three months. We are also working with collaborators to consider and pursue options that might allow for even more investigational doses to be available prior to licensure.

Merck is simultaneously making progress with regulatory submissions for V920. As previously announced in November 2018, the submission of a rolling Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for V920 is underway. The European Medicines Agency (EMA) recently accepted the Marketing Authorization Application (MAA) for V920 and will begin review of the application. In parallel, and in close collaboration with FDA and EMA, submissions have also been made to the WHO to achieve prequalification status and to health authority representatives of the African Vaccine Regulatory Forum (AVAREF). Thanks to strong collaborations across multiple partners, reviews are being pursued in as concurrent and accelerated a manner as possible. These regulatory submission milestones represent important progress toward registration, and if approved, helping enable more sustainable access of an Ebola vaccine to those who need it most, including communities in countries at risk for Ebola outbreaks in Africa.

About Merck’s Investigational V920 Ebola Zaire Vaccine

V920, Merck’s investigational Ebola Zaire vaccine, 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 Ebola outbreak in western Africa was at its peak, Merck licensed V920 from NewLink Genetics. Since that time, the company has worked closely with a number of external collaborators to enable a broad clinical development program with partial funding from the U.S. Government, including the Department of Health and Human Service’s Biomedical Advanced Research Development Authority (BARDA) under Contract No. HHSO100201700012C and other contracts, as well as the Department of Defense’s Defense Threat Reduction Program (DTRA) and Joint Vaccination Acquisition Program (JVAP), among others. Merck is responsible for the research, development, manufacturing and regulatory efforts in support of V920. The company has committed to working closely with other stakeholders to accelerate the continued development, production and, if licensed, distribution of the vaccine.
