TRIAL DESCRIPTION
Public title A Phase 1, Open-Label, Dose-Escalation Study to Evaluate the Safety and Immunogenicity of the BPSC1001 (VSV¿G-ZEBOV) Ebola Virus Vaccine Candidate.
Official scientific title A Phase 1, Open-Label, Dose-Escalation Study to Evaluate the Safety and Immunogenicity of the BPSC1001 (VSV¿G-ZEBOV) Ebola Virus Vaccine Candidate in Healthy Adult Volunteers in Lambaréné, Gabon.
Brief summary describing the background and objectives of the trial The world is currently experiencing the worst Ebola outbreak in history, with its most devastating effects being felt in West Africa. Ebola has become epidemic and is claiming thousands of lives in Guinea, Liberia and Sierra Leone as well as isolated cases in other countries. In response, WHO is coordinating a global Response Road Map with the goal to stop Ebola transmission globally within 6-9 months. This study is part of a WHO facilitated consortium (the VEBCON consortium), and aims to provide first clinical data in Africa on a VSV¿G-ZEBOV Ebola candidate vaccine. It is designed to establish safety, tolerability and immunogenicity of VSV¿G-ZEBOV, a vaccine candidate by investigating 5 different dosages in sub-Saharan African adult populations living in Lambarene, Gabon. 115 volunteers were vaccinated into five groups and vaccination of subjects in each cohort will proceed in a staggered manner. Data will be obtained about immediate and long term reactogenicity and tolerabiltiy, adverse events and blood markers of immune response over a 5 years period after vaccination.
