Partnership for Research on Ebola Vaccines in Liberia (PREVAIL)

Ebola Virus

Background: - Ebola virus disease (EVD) affects many people in Liberia and other countries in West Africa. It is caused by the Ebola virus and makes people sick with fever, headache, vomiting, diarrhea, rash, and bleeding. About half the people with EVD die. There is no approved treatment for it. Researchers are studying two Ebola vaccines. The vaccines do not cause Ebola. Objectives: - To study the safety and efficacy of two Ebola vaccines. Eligibility: - Adults 18 and older who live in Liberia and are at risk for Ebola infection but have never had Ebola. Design: Participants will give information including birthdate, gender, occupation, and location of home. They will give contact information for themselves and 2 alternate contacts. They will give a history of their contact with people with Ebola. Some participants may have a physical. They may have blood taken. Participants will be injected with either an Ebola vaccine or a placebo with a needle in the upper arm. The placebo is a salt solution. Participants will have blood taken. Participants will be watched for 30 minutes. Participants will return to the clinic 1 week and 1 month after they get the shot. They will have blood taken. After that, participants will be contacted monthly to discuss how they are feeling. They may be contacted by phone, may visit the clinic, or may have a home visit. The study ends 8-12 months after participants get the shot. If one of the vaccines works against Ebola and does not have many side effects, participants can get the vaccine if they did not get it in the study.

Vaccine Treatment for Ebola Virus in Healthy Adults (V920-001)

Ebola Virus

This is a study of the anti-Ebola vaccine vesicular stomatitis virus (VSV) ZEBOV (Zaire ebolavirus) also known as V920 and BPSC-1001. The purpose of this study is to test how safe the vaccine is in humans and how well it makes the human immune system cause an immune- or defense-response to Ebola virus. This vaccine will be studied at different doses.

A Study of 2-dose Vaccination Regimen of Ad26.ZEBOV and MVA-BN-Filo in Infants

Ebola Virus Disease

The purpose of this study is to assess the safety and reactogenicity of a heterologous 2-dose regimen utilizing Ad26.ZEBOV (first vaccination; Dose 1) and MVA-BN-Filo (second vaccination; Dose 2) administered intramuscularly (IM) on Days 1 and 57, respectively (Main Study) and also to provide the heterologous 2-dose vaccination regimen (Ad26.ZEBOV on Day 1 and MVABN-Filo on Day 57) to participants in the control arm of the main study (Extension Phase).

Ebola Sudan Chimpanzee Adenovirus Vector Vaccine in Healthy Adults

Ebola Virus

RV 508 was a Phase I, open-label, dose-escalation study to examine the safety, tolerability and immunogenicity of an investigational Ebola vaccine in healthy adults. VRC-EBOADC086-00-VP, a chimpanzee adenovirus serotype 3 vector-based Ebola vaccine, encodes wild type (WT) glycoprotein (GP) from the Sudan strain of Ebolavirus and is administered intramuscularly (IM).

Placebo Controlled, Dose Response, Safety and Immunogenicity Study of Vesicular Stomatitis Virus...

Ebola Virus

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.

Experimental Vaccine for Prevention of Ebola Virus Infection

Ebola Hemorrhagic FeverEbola Virus Disease4 more

This study will determine if an experimental vaccine to prevent Ebola virus infection is safe and what side effects, if any, it causes. Ebola virus infection may range from mild to severe, and may cause breathing problems, severe bleeding, kidney problems and shock that can lead to death. The vaccine used in this study contains man-made genetic material similar to one part of the Ebola virus, which is designed to stimulate an immune response to the virus. The vaccine itself cannot cause Ebola virus infection because it does not contain any Ebola virus. Participants are assigned to one of three groups as they enter into the study. Of the first 16 people in the study, 12 receive the lowest study dose of vaccine and 4 receive placebo (an inactive substance). If this dose is safe, then of the next 16 people who enter the study, 12 receive a higher dose of the vaccine, and the remaining 4 receive placebo. If this dose is safe, the final 12 people in the last group of 16 receive the highest study dose, and 4 receive placebo. The vaccine is given as a single injection in the arm on the day of enrollment. Participants keep a diary for 5 days, recording their temperature, symptoms and any reaction at the injection site. They call a study nurse the day after vaccination to report how they feel, and they return to the clinic approximately six times for follow-up evaluations. These visits may include a check of vital signs, physical examination, blood and urine tests, or other medical tests if needed. ...

INO-4201 as Booster in Healthy VSV-ZEBOV Vaccinees

Ebola Virus Disease

Ebola virus disease (EVD) is a serious illness with a high fatality rate. Currently only one vaccine is available, VSV-ZEBOV/Ervebo; this vaccine is clinically effective and has been deployed as a preventive measure during recent Ebola outbreaks. The durability of protection afforded by this vaccine is unknown, however, and it is thought that a booster vaccination may be required to maintain immune responses. Recently, a synthetic DNA vaccine, INO-4201, was tested in humans and showed good immunogenicity and an enhanced safety profile. This study aims to test whether the DNA-based candidate INO-4201 can be used as a booster in healthy volunteers previously vaccinated with VSV-ZEBOV.
