A new European consortium has been formed which includes GlaxoSmithKline (GSK) and three leading research institutions to help further advance development of a candidate vaccine against Ebola, which is being co-developed by GSK and the US National Institutes of Health (NIH).

The consortium is backed by funding of EUR 15.1 million ($18.9 million) from the European Commission (EC) Directorate General for Research and Innovation as part of its dedicated Horizon 2020 program supporting research into treatments and vaccines for Ebola. The consortium also expects to receive an additional EUR 1.4 million from the Swiss government.

The funding is already helping to implement an ongoing trial of an Ebola candidate vaccine being carried out in 120 healthy adult volunteers in Lausanne, Switzerland. If the safety and immunogenicity data from this and other ongoing Phase I trials are encouraging, the EC funding will enable the consortium to begin larger Phase II trials in Africa, which could start as early as January 2015.

These trials will evaluate the safety and ability of the GSK/NIH vaccine candidate to create an immune response against Ebola in adults and children and will be carried out at established clinical study centers in West Africa, outside the most heavily-affected areas. It is anticipated that they will also investigate the effect of booster vaccination, if early stage booster trials underway at the University of Oxford are successful.

Beyond this EbolaVac project, GSK is working with the World Health Organization (WHO), regulators, and other stakeholders to prepare for efficacy trials in Ebola affected countries including Sierra Leone and Liberia, should the Phase I trials be successful. Further work continues to determine how and when near-term supplies of the Ebola candidate vaccine could be made available for targeted vaccination of additional healthcare workers and other people at high risk of infection in the affected countries, where the impact would be most likely to limit the further spread of the epidemic. Its future use in mass vaccination campaigns will depend on whether the vaccine candidate provides protection against Ebola without causing significant side-effects and how quickly large enough quantities can be made. The vaccine consists of a single Ebola virus protein, which belongs to the Zaire strain circulating in West Africa, engineered in a chimpanzee adenovirus vector. As it does not contain infectious Ebola virus material, it cannot cause a person who is vaccinated to become infected with Ebola, but should generate immune responses aimed at protecting subjects when exposed to the Ebola virus.
