A Systems Biology Phase 1 Evaluation of the Safety, Reactogenicity, and Immunogenicity of Chimpanzee Adenovirus Type 3- Vectored Zaire Ebolavirus (ChAd3-EBO-Z) and Modified Vaccinia Ankara- Vectored Multivalent Filovirus (MVA-BN(R)-Filo) Vaccine Candidates

In Brief

A Phase 1 clinical trial evaluating ChAd3-EBO-Z, MVA Multi-Filo Ebola Vaccine, and 1 other intervention for Ebola Disease and Immunisation. Completed, enrolled 61 participants across 1 site.

Detailed Summary

This initial, proof of concept study will focus on identifying significant differences in response to the Ebolavirus Zaire vaccine (ChAd3-EBO-Z) when administered with placebo, MVA-BN(R)-Filo, or ChAd3-EBO-Z boosters after 8 days. All 60 participants will receive the ChAd3-EBO-Z vaccine and then randomized into each booster group (20 receiving each type of booster). Subjects will be followed-up for 6 months to monitor for safety outcomes and efficacy measures. There is no formal hypothesis for this study. The primary objective of this study is to assess the safety and reactogenicity of study products by study group when administered IM to healthy adults.
