Active clinical trials for "Virus Diseases"

This Phase 3 study was intended to assess the relative efficacy of the Quadrivalent VLP Influenza Vaccine during the 2018-2019 influenza season compared to a licensed vaccine in elderly adults 65 years of age and older. One dose of VLP Influenza Vaccine (30 μg/strain) or of Comparator (15 μg/strain) was to be administered to 12,738 participants.

The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) to prevent viral infections that may happen after allogeneic stem cell transplant. Allogeneic means the stem cells come from another person. VSTs are cells specially designed to fight viral infections that may happen after a stem cell transplant (SCT). Stem cell transplant reduces your ability to fight infections. Viral infections are a common problem after transplant and can cause significant complications. Moreover, treatment of viral infections is expensive and time consuming, with families often administering prolonged treatments with intravenous anti-viral medications, or patients requiring prolonged admissions to the hospital. The medicines can also have side effects like damage to the kidneys or reduction in the blood counts, so in this study we are trying to find a way to prevent these infections.

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.

RV 507 was a Phase I, open-label study to examine the safety, tolerability and immunogenicity of an investigational Marburg vaccine given by intramuscular (IM) injection to healthy adults. The study was a dose escalation of VRC-MARADC087-00-VP, a chimpanzee adenovirus serotype 3 (cAd3) vector vaccine, which encodes wild type (WT) glycoprotein (GP) from Marburgvirus.

This Phase 3 study is intended to assess the efficacy of the Quadrivalent VLP Influenza Vaccine during the 2017-2018 influenza season in healthy adults 18 to 64 years of age. One dose of Quadrivalent VLP Influenza Vaccine (30 μg/strain) or of placebo will be administered to approximately 10,000 participants

The purpose of this study is to continue the evaluation of antibody persistence through 11 to 15 years after first booster with Tick-Borne Encephalitis (TBE) vaccine. This study will further investigate the booster response in subjects who will receive their second booster dose* in this study. * Any booster given in this study will be the second that the subject has received (with regard to the follow-up of the previous study).

LA rVSVΔG-ZEBOV-GP -02-PED is a Phase 1/2, randomized, controlled open label trial. The LA rVSVΔG-ZEBOV-GP -02-PED trial aims primarily to assess the clinical significance of shedding of the rVSV RNA following vaccination with the rVSVΔG-ZEBOV-GP vaccine in children. The vaccine doses of ≥7.8 x 107 pfu will be evaluated and compared to vaccination with varicella vaccine as a control. In addition, the closest contact persons of the vaccinees will be monitored for possible transmission of the viral vaccine vector. The study will enroll children of two age groups living in Lambaréné, Gabon. Children will be followed-up for 12 months post vaccination. The 1-2 closest contact persons of each participant will be involved in the monitoring of rVSV transmission. They will be followed until day 56 post- vaccination of their children/ sibling.

An open label, dose escalation, and dose expansion study to evaluate the safety, reactogenicity and immunogenicity of two SARS-CoV-2 DNA plasmid vaccine candidates, VB10.2129 (C1) and VB10.2210 (C2). tThree dose levels will be tested. IM administrations 21 days apart. Part 1 is a dose escalation phase and Part 2 is a dose expansion phase. In Part 2 a selected dose will be tested further in additional healty volunteers.

This is a A Phase III, Open label, Multicenter, Single Arm Study to assess the Safety, Tolerability and Immunogenicity of VLA2001 in volunteers aged ≥ 56 years. Approximately 300 participants are enrolled in a non-randomized manner.

In the SAVE study patients with lower respiratory tract infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at high risk for progression to serious respiratory failure will be detected using the suPAR biomarker. They will begin early treatment with anakinra in the effort to prevent progression in serious respiratory failure.
