Filter by:The purpose of this study is to evaluate the post-vaccination immune status at different time points in subjects immunized against Ebola Virus Disease; to select an optimal regimen of product administration; and, to assess safety of medicinal product GamEvac-Combi - Combined Vector-Based Vaccine against Ebola Virus Disease, 0.5 ml+0.5 ml/dose, following the immunization with a half (0.25 ml+0.25 ml/dose) and full (0.5 ml+0.5 ml/dose) therapeutic doses.
Background: Some people have Ebola virus in their body for months after they recover from Ebola virus disease. Some may have health problems from the virus while others are fine. These people may be able to pass the virus to others. There are currently no drugs for people who have survived Ebola virus disease but still have the virus in their body. A new drug, GS-5734, might help get rid of Ebola virus in semen. Objective: To test if GS-5734 helps get rid of Ebola virus in semen and is safe for humans. Eligibility: Men who participated in the Ebola survivor study (PREVAIL III) and have evidence of the Ebola virus in their semen Design: Participants will be screened with: Questions Physical exam Eye exam Blood tests 2 semen samples if they have not had it tested recently Participants must live near the study site in Liberia for 6 months. Participants will be put into 1 of 2 study groups. They will have an infusion of either GS-5734 or a placebo every day for 5 days. A plastic tube is put into an arm vein. The infusion lasts 1 hour. Participants will be observed for 1 hour after. They will provide a semen sample on infusion day 4. After the infusions, participants will have 5 visits in the first month, then 1 per month for 5 more months. These include giving a blood and semen sample. Blood tests are performed before and after each infusion and the last visit (5 month visit) will also include an eye exam. When the study is over, if the study drug works and is safe, participants who got the placebo can get the study drug.
The purpose of this study is to assess the safety profile of the Zaire Ebola vaccine and the strength of the immune response.
The purpose of this study is to explore the therapeutic efficacy of Favipiravir, a broad-spectrum antiviral drug against severe cases of Ebola Virus Disease (EVD), which is the most difficult aspect for clinical management of EVD due to its high fatality rate.
The aim of our study is to assess the analytical and clinical performance of the FilmArray (FA) BioThreat-E test (BioFire®) for the diagnosis of Ebola virus disease in the field in Guinea versus conventional molecular techniques.
The purpose of this study is to assess the safety, tolerability and immunogenicity of different vaccination schedules of Ad26.ZEBOV and MVA-BN-Filo administered intramuscularly (IM) as 2-dose heterologous regimens in healthy and in HIV-infected adults.
A Single-Center, Randomized, Blind, Phase II Clinical Trial to Evaluate the Safety and Immunogenicity of the Adenovirus Type 5 Vector Based Ebola Virus Disease Vaccine (Ad5-EBOV) in Healthy Adults Aged Between 18 and 50 years in Sierra Leone.
The purpose of this study is to evaluate the safety, infectivity, and immunogenicity of the HPIV3-EbovZ GP Ebola vaccine candidate in healthy adults.
The purpose of this study is to assess the safety, tolerability and immunogenicity of three heterologous prime-boost regimens for Ebola vaccines Ad26.ZEBOV and MVA-BN-Filo. The study will include healthy adults and elderly participants, HIV infected participants and healthy children in 2 age strata.
Since its first outbreak occurred in 1976, Zaire Ebola virus have been associated with 14 outbreaks reported up to 2014. The Zaire Ebola virus in 2014 causing the most serious outbreak was considered to be a new epidemic strain, with GP homology of the gene was only 97.6%, compared to the GP gene of the strain in 1976. This investigational Ad5-EBOV vaccine was developed according to the 2014 epidemic Zaire strain and formulated as freeze-dry products which could be stored at 4℃. In 2014, a single center, double-blind, placebo control, dose-escalation phase 1 clinical trial was performed in Taizhou, China. Our findings show that the Ad5-EBOV vaccine is safe and robustly immunogenic. One shot of the high dose vaccine could mount glycoprotein-specific humoral and T-cell response against Ebola virus in 14 days. The investigators intent to evaluate the safety and immunogenicity of a booster dose of the recombinant Ebola adenovirus vector vaccine (Ad5-EBOV) in healthy adults after primary immunization in this add in study. The investigators expect that the boosting immunization with a same vaccine for primary immunization is possible and could confer a longer-lived protection when needed. The phase I trial has been unblind 28 days after the primary vaccination, but all the subjects are still kept blind as well as the laboratory staffs. Therefore, this booster vaccination trial will be conduct in single blind.
