Filter by:The purpose of this first time-in-human (FTiH) study is to evaluate the safety, reactogenicity and immunogenicity of different dose levels of an experimental rabies glycoprotein G (RG) vaccine (RG-SAM [CNE] vaccine), made using a new technology, when administered intramuscularly (IM) on a 0, 2, 6 *-month schedule to healthy adults. * There will be no vaccinations with the third dose of any of the study treatments.
The purpose of this study is to evaluate the effect of JNJ-53718678 on the development of respiratory syncytial virus (RSV) lower respiratory tract infection (LRTIs) in adult hematopoietic stem cell transplant (HSCT) recipients with RSV upper RTI.
This is a randomized, placebo-controlled, single-center, dose finding phase I trial in healthy adult volunteer participants consisting of two phases, an unblinded dose escalation and an observer-blinded treatment phase. The aim is to investigate the safety, tolerability and immunogenicity of MV-LASV after administration of two different dose levels of MV-LASV. Placebo will be applied to blind the different Treatment schedules.
MOSAIC is a single-blind experimental medicine study to determine the extent to which different prime-boost combinations of model immunogens based on HIV-1 envelope proteins influence the diversity of B and T cell responses.
The purpose of this study is to assess the efficacy of a fixed dose combination (FDC) of glecaprevir/pibrentasvir (G/P) given for 4 weeks in acute hepatitis C (HCV)-infected participants, with or without HIV-1 coinfection.
Globally, about 248 million people are chronic HBV surface antigen carriers, and about 5% of them also had hepatitis delta virus (HDV) infection as well. The prevalence of HBsAg in Egypt is intermediate (2-7%) . Hepatitis D virus (HDV) is an incomplete RNA virus that needs hepatitis B surface antigen (HBsAg) to help its replication. HDV is considered a subviral particle because it depends on HBV for its propagation. Combined HDV- HBV infection produces more severe liver affection than HBV alone. HDV infection leads to both of acute and chronic liver illnesses. Acute HDV infection can occur at the same time with acute HBV infection (coinfection) or can be superimposed on the top of chronic HBV infection. About 20% to 30% of coinfections of HDV and HBV in humans develop fatal fulminant hepatitis versus 2% of patients with acute hepatitis B mono-infection. Worldwide, Hepatitis D virus (HDV) infection present in more than 15 million people and it is endemic in the Middle East . In Upper Egypt, data about the prevalence, clinical, laboratory and virological characters of Hepatitis D virus-infected patients is rare. This study aims were: 1. To estimate the prevalence of hepatitis D virus infection among HBsAg positive individuals. 2. To determine the clinical, laboratory and virological characters of HDV infected patients.
An open-label, single arm phase II study of the candidate Ebola Vaccine Ad26.ZEBOV/MVA-BN®-Filo
This study collects data on microbiological factors and lung function parameters (e.g. spirometry, body plethysmography, lung-MRI) to assess their interaction on the lung growth and lung development of infants and children with Cystic Fibrosis (CF).
The study will assess the safety and efficacy of AT-527 in combination with daclatasvir after 8 or 12 weeks of treatment.
The purpose of this study is to use VSTs (virus-specific T cells) from a donor that is a partial HLA (human leukocyte antigen) match with the patient to treat viral infections after an allogeneic hematopoietic stem cell transplant (HSCT). These cells may also have value in CAR-T recipients who have received a product that depletes virus specific T cells. The patient must have had a myeloablative or non-myeloablative allogeneic HSCT using either bone marrow, single/double umbilical cord blood, or peripheral blood stem cells (PBSC) or CAR T cell product targeting an antigen expressed on virus specific T cells. After a transplant, while the immune system grows back, the patient is at risk for infection. Some viruses can stay in the body for life and are normally controlled by a healthy immune system, but if the immune system is weakened, like after a transplant, they can cause life threatening infections. He/she must have had an infection with one or more of the following viruses -Epstein Barr virus (EBV), cytomegalovirus (CMV), adenovirus (AdV), Human polyomavirus type I (BKV), and human polyomavirus type II (JCV)- that has persisted or recurred despite standard therapy. In this study, the investigators want to use white blood cells that have been trained to treat viral infections. In an earlier study the investigators showed that treatment with such specially trained T cells has been successful when the cells are made from the transplant donor. However as it takes 1-2 months to make the cells, that approach is not practical for patients who already have an infection. In a subsequent study, the investigators were able to create multivirus-specific T cells (VSTs) from the blood of healthy donors and created a bank of these cells. The investigators then successfully used these banked cells to treat virus infections after a stem cell transplant. In this study the investigators have further modified their production method to decrease the potential side effects and the investigators want to find out if they can use these banked VSTs to fight infections caused by the viruses mentioned above.
