Brief Summary:
Ebola virus has infected and killed people, mostly in Africa. In 2014, the Ebola virus has affected several thousand people. There is no approved effective way to treat or prevent Ebola. Researchers are trying to develop a vaccine for it. This is a study of the anti-Ebola vaccine BPSC-1001 to see if it is safe and to see how it affects people's immune system.

Condition or disease Intervention/treatment Phase
Ebola Virus Biological: BPSC-1001 Vaccine Other: Placebo Phase 1

Detailed Description:

Between 1994 and the present, there have been many Ebola viruses (EBOV) outbreaks affecting mostly central Africa. However, the 2014 West African outbreak significantly exceeds all previous outbreaks in geographic range, number of individuals affected and in disruption of typical activities of civil society.

This is a Phase 1 safety and tolerability study to evaluate a novel vaccine to Ebola using a live replicating vesicular stomatitis virus (VSV) replacing the gene encoding the G envelope glycoprotein with the gene encoding the envelope glycoprotein from the Zaire strain of Ebola (VSVΔG-ZEBOV also known as BPSC-1001).
