Filter by:The purpose of this first time in human (FTiH) study is to assess the safety, reactogenicity and immunogenicity of 2 doses of the RSV investigational vaccine, when administered intramuscularly according to a 0, 1 month schedule, in healthy adults aged 18 to 45 years.
The primary objective of this study was to evaluate the efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) with or without ribavirin (RBV) in Egyptian adults with chronic genotype 4 hepatitis C virus (HCV) infection.
This is a clinical trial in which healthy volunteers will be administered two experimental Ebola vaccines: ChAd3-EBO Z and MVA-EBO Z. Two groups of volunteers will be vaccinated with both vaccines one after the other in a prime/boost regimen. All ChAd3-EBO Z doses are 2.5 x 10^10 - 3.7 x 10^10 vp and all MVA-EBO Z doses are 1.0 x 10^8 pfu. All volunteers will receive a ChAd3-EBO Z priming vaccine and a MVA-EBO Z boosting vaccine 7 days later. The site of administration of the MVA-EBO Z vaccine differs between the two groups: Group 1 will receive the MVA-EBO Z vaccine in the same arm as the ChAd3-EBO Z vaccine. Group 2 will receive the MVA-EBO Z vaccine in the opposite arm from the ChAd3-EBO Z vaccine. The study will assess the safety of the vaccinations, and the immune responses to vaccination. Immune responses are measured by tests on blood samples. The ChAd3-EBO Z and MVA-EBO Z vaccines are called viral vectored vaccines. They are made from viruses which are modified so that they cannot multiply. The viruses have extra DNA in them so that after injection, the body makes Ebola proteins (but Ebola does not develop), so that the immune system builds a response to Ebola without having been infected by it. Healthy volunteers will be recruited in Dakar, Senegal. The study will be funded by GSK.
The purpose of this study is to assess the safety and immunogenicity of the investigational ChAd3-EBO-Z vaccine administered to approximately 3 000 adults in Africa as a single IM dose Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all subjects in the study will receive the investigational ChAd3-EBO-Z vaccine. The subjects in the Group EBO-Z will receive the vaccine at Day 0 of the study, whereas the subjects in the Group Placebo/ EBO-Z will receive a placebo at Day 0 (as a control) and will receive the investigational ChAd3-EBO-Z vaccine at Month 6, provided that no safety concerns are raised. In addition, vaccinating all subjects in the study with the investigational ChAd3 EBO Z vaccine will allow an increase of the safety database of the investigational vaccine. In case the geographic range of Ebola virus Zaire (EBOV) transmission expands to encompass any of the regions where this trial is conducted, earlier administration of the investigational ChAd3-EBO-Z vaccine to the subjects in the Group Placebo/ EBO-Z will be considered in that region.
The primary objectives of this study are to evaluate the efficacy, safety and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) for 12 weeks in participants with chronic HCV infection who were coinfected with HIV-1.
This phase II trial studies how well donor cytotoxic T lymphocytes work in treating patients with malignancies with BK and/or JC virus. Cytotoxic T lymphocytes are made from donated blood cells that are grown in the laboratory and are designed to kill viruses that can cause infections in transplant patients and may be an effective treatment in patients with malignancies with BK and/or JC virus.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of ALS-008176 following oral administration of single ascending dose of ALS-008176 in healthy Japanese adult participants.
The study is a single centre, single arm, open-label, proof of concept study enrolling 20 adult primary liver transplant recipients with genotype 1 HCV infection. Subjects will receive Sofosbuvir (SOF) and Ledipasvir (LDV) starting at time of liver transplantation (OLT) and continues for 12 weeks. Subjects will be receive 24 week post-treatment follow up.
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) with or without ribavirin (RBV) in adults with chronic hepatitis C virus (HCV) infection.
Administration of DPX-RSV(A), a Respiratory Syncytial Virus vaccine containing Respiratory Syncytial Virus (RSV) SHe antigen and DepoVaxTM adjuvant to healthy adults ≥50-64 years of age.
