Filter by:This is a single center, open, dose-escalation phase 1 clinical trial. This study will determine the safety and side-effect profile, and immunogenicity of an investigational Ad5-EBOV vaccine in Healthy Adult Africans aged between 18-60 years in China.
The purpose of this study is to determine whether multiple therapeutic regimens are effective in the treatment of Ebola Virus Disease (EVD)
Ebola virus causes an infection known as Ebola virus disease (EVD). This it is generally a severe disease which can also lead to death. The 2014 outbreak of EVD in West Africa is the largest ever. Researchers want to develop a vaccine to prevent Ebola infection. This study will assess the safety of a single dose of the bivalent Ebola Zaire candidate vaccine VRC-EBOADC069-00-VP (cAD3-EBO) when administered to healthy Malian adult volunteers, age 18-65 years (mostly health care workers and other front line workers [e.g., individuals who incinerate contaminated materials]), at one of 2 dosage levels, 2.0 x 10(10) vp or 2 x 10(11) vp. It is impossible for someone to get an Ebola infection from this vaccine. Heterologous booster dose allocation - Each participant will be offered the opportunity to be included in the booster step of this study. After obtaining consent and the additional review of pertinent medical history, participants in each group will be randomized to receive the candidate booster vaccine, MVA-EbolaZ or placebo. This will be the first clinical trial in Mali with bivalent cAd3-based Ebola vaccine and the first where the dosage level contains > 10(11) vp. It follows completion of a Phase Ib trial in Malian health care workers that tested three dosage levels of monovalent cAd3-EBO Z vaccine. The data generated in West Africans (Mali) on the tolerability and immunogenicity of the bivalent vaccine will be compared to clinical and immunologic responses documented in in parallel studies in East African subjects (Uganda) and North American subjects (NIH, Bethesda, MD, USA). Objectives: - To see if an Ebola vaccine is safe and to study immune responses to it. - To study the effect of the MVA-EbolaZ booster on the immune response Eligibility: - Healthy adults ages 18-65.
A Phase I/II Pilot Clinical Trial to Evaluate the Efficacy and Safety of Ebola Virus Disease (EVD) Convalescent Plasma (ECP) for treatment of EVD.
There is no specific treatment for Ebola Virus Disease (EVD). Current EVD care are supportive, and includes intravenous or oral rehydration, nutrition, pain killers, treatment of coinfections with antibacterial and antimalarial drugs, and blood transfusion when appropriate. Despite these interventions, mortality remains high since the ongoing Ebola outbreak in West Africa was declared in April. Potential anti-Ebola specific interventions include convalescent plasma, monoclonal and polyclonal antibodies, small inhibitory RNA (siRNA), synthetic adenosine analogues or RNA polymerase inhibitors. All these interventions are considered investigational due to lack of data in humans with EVD. In this study, the investigators chose to study the efficacy of favipiravir because this drug: - showed anti-Ebola efficacy in immunodeficient murine models; - has been studied in thousands of adult humans participating in anti-influenza trials, with good tolerance; it has been approved for treating novel or resistant influenza infections in Japan; - is immediately available; - can be used orally, and can be easily given in both adults and children because pills can be crushed and mixed in food or liquids; - has recently been used in Europe for treating several patients with EVD; the French drug safety agency (ANSM) has reviewed published data as well as data provided by the firm (Toyama Chemical Co., Ltd), and approved its compassionate use in EVD. Here the investigators propose to assess the efficacy of high-dosed favipiravir in reducing mortality in humans with EVD. In the present trial "JIKI" (means "Hope" in "Kissi" language), investigators, sponsor, scientific advisory board and safety monitoring board will be coordinated in a very reactive way, so that any new fact can be discussed rapidly and the research plan can be adapted accordingly (change in drug dosage; use of drug combination; combination with another strategy such as passive immunization with convalescent plasma, etc.).
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℃. This is a single center, double-blind, placebo control, dose-escalation phase 1 clinical trial. This study will determine the safety and side-effect profile, and immunogenicity of an investigational Ad5-EBOV vaccine.
The purpose of this study is to evaluate the efficacy and safety of amiodarone in the treatment of patients afflicted with Ebola virus disease.
Previous Ebola outbreaks have been limited to individual countries and contained by infection control activities. The current outbreak in West Africa is international, and air travel has resulted in a number of infected travellers crossing national borders. There are currently no specific treatments generally available for Ebola and the mortality is high, particularly in countries with limited intensive care facilities. There is currently no vaccine and the personal protection required by healthcare workers treating patients is cumbersome and requires full compliance to be protective. There is now a consortium (VEBCON collaboration) of four clinical centres (in Kenya, Gabon, Switzerland and Germany), WHO and New Link Genetics (the vaccine manufacturer) under which this study will be conducted. The investigators are conducting this trial, a Phase I, open-label, dose escalation trial, designed to establish safety, tolerability and immunogenicity of two doses of VSVΔG-ZEBOV, an Ebola Virus Vaccine Candidate for the first time in sub-Saharan African populations. The investigators plan to vaccinate 40 volunteers in Kenya. The trial will be conducted at the KEMRI-CGMR Coast site where healthcare workers (both clinical and laboratory) will be the primary target population as they are likely to be the recipients of a protective vaccine. The investigators will vaccinate a cohort of 20 volunteers at a low dose and then vaccinate a further cohort of 20 volunteers at full dose. Each volunteer will receive one dose of the vaccine. The investigators will follow them up for a period of one year looking to their safety and immunogenicity endpoints.

This study will test two new vaccines, one for Ebola and one for Marburg virus, to see if they are safe, if they have side effects, and if they create an immune response in people who receive them.
