Active clinical trials for "Hemorrhagic Fever, Ebola"

The study is designed to establish safety, tolerability and immunogenicity of rVSVΔG-ZEBOV-GP (BPSC1001), an Ebola Virus Vaccine candidate (recombinant vesicular stomatitis virus (VSV) expressing the envelope glycoprotein of Ebola Virus Zaire), investigated at three different dose levels in 30 healthy adults in Germany. This study is part of the WHO led VEBCON consortium that is aiming to generate harmonized data for the rVSVΔG-ZEBOV-GP (BPSC1001) vaccine candidate to allow optimized rapid decisions on dose and safety.

This is an emergency, phase 2/3, open-label, non-randomized, clinical trial that will evaluate Convalescent Plasma (CP) added to standardized supportive care (SC) in patients with confirmed Ebola Virus Disease (EVD). No patient will be refused CP when compatible products are available and all efforts will be made to maximize CP availability during the study. EVD patients recruited during the period before CP becomes available or for whom no compatible CP is available will be given SC and will be followed for study outcomes. Data from these SC patients will be the used as comparator in the analysis of the study. The primary objective of the study is to assess if CP + SC improves the 14 day survival of patients, compared to SC alone. The Investigators aim to enroll a total number of 130 - 200 patients who will be treated treated with CP assuming equal numbers of patients treated with SC alone. If there would be insufficient patients treated with SC, patients treated at the research site prior to study start may be included in the comparison group. Patients will be recruited in the Ebola Treatment centre managed by Medecins Sans Frontieres (MSF) in Conakry, Guinea. All patients and/or relatives presenting at the centre will be informed about the study, and will be invited to provide consent at the time of admission inside the treatment centre. Only patients for whom ebola infection is confirmed with polymerase chain reaction (PCR) will be enrolled in the study. After inclusion, eligibility to the intervention will be reassessed on regular intervals. If the eligibility criteria are not met by 48 hours after inclusion, only SC will be continued. In line with the guidance of the World Health Organization (WHO), two units of CP will be given. EVD patients will be transfused with ABO-compatible CP using standard procedures. Details on the modalities of transfusion can be found in the WHO guidance document and the MSF guidelines on blood transfusion. All patients will be under close observation for transfusion-related adverse reactions during and up to 4 hours after transfusion. 24 hours after the start of transfusion, a blood sample will be collected for viral load assessment. All other aspects of patient management will be according to MSF clinical guidelines. The decision to discharge a patient should be taken on clinical grounds, but can be supported by the laboratory results. After discharge, the patient will be followed up by the study team until day 30.

The purpose of this study is to characterize the safety and pharmacology of single administrations of AVI-6002, a post-exposure prophylaxis candidate treatment for Ebolavirus.

Background: - Ebola is a viral infection that can spread quickly and causes life-threatening disease. Right now there is an Ebola outbreak in many countries in West Africa. There are no approved treatments for Ebola. But possible treatments are being developed. Researchers need to study these treatments to see if they help people get better. Objective: - To identify possible Ebola treatments. Also, to learn if adding 1 or more experimental drugs to advanced Ebola care can reduce the risk of death. Eligibility: - People who have recently been diagnosed with Ebola, usually by a test called the Polymerase Chain Reaction (PCR), and have been hospitalized in an isolation unit for treatment. Design: Participants will be randomly assigned to Group A or B. Both groups will get advanced level care. One group will also get an experimental drug. Participants may have blood tests. They may have another PCR test. Researchers will try to learn how the participant got Ebola. Participants put in the experimental drug group may start taking medicine within 24 hours of enrollment. It may be given by mouth or intravenously. Additional doses may be needed. Participants may have a series of timed blood tests over the first 24 to 48 hours after they take the medicine. Blood will be drawn frequently. Other body fluids (urine, stool, vaginal fluid, etc.) may also be collected. Participants will be followed for up to 60 days. They may be evaluated for any long-term effects of the experimental treatment(s). They may be asked to return for 1 or more outpatient visits. For consenting participants, follow-up will be extended for up to one full year past Day 58 with contact/visits every 1-3 months to assess for a history of signs or symptoms potentially consistent with late onset of virologic relapse syndrome.

This is a 2-part, first-in-human dose-ranging study to evaluate the safety, tolerability and pharmacokinetics of escalating doses of BCX4430 administered via intramuscular (IM) injection in healthy subjects. In part 1, subjects will receive a single dose of BCX4430; in part 2 subjects will receive BCX4430 for 7 days.

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.

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℃. 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.

The purpose of the study is to assess the long-term safety profile of Ad26.ZEBOV and MVA-BN-Filo in participants previously exposed to these vaccines in Phase 1, 2, or 3 clinical studies.

The purpose of this study is to assess the safety profile of the Zaire Ebola vaccine and the strength of the immune response.
