Active clinical trials for "Virus Diseases"

The purpose of this study is the evaluation of the safety and immunogenicity of two candidate Ebola vaccines Ad26.ZEBOV and MVA-BN-Filo, in a 2-dose heterologous regimen.

This is a multiple sites phase II trial, randomized, observer-blind, dose ranging, placebo-controlled study to evaluate the immunogenicity, safety, and tolerability of a single intramuscular injection of plant-based Seasonal VLP Quadrivalent Influenza Vaccine administered in elderly subjects (50 years old and more). A total of four hundred fifty (450) subjects will be randomized in six (6) groups of 75 subjects to receive one injection of either a non-adjuvanted low, medium or high dose level of VLP, a low or high dose level of VLP of the quadrivalent VLP influenza vaccine combined with Alhydrogel® as adjuvant or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80)

The purpose of this study is to assess the safety and reactogenicity of a heterologous 2-dose regimen utilizing Ad26.ZEBOV (first vaccination; Dose 1) and MVA-BN-Filo (second vaccination; Dose 2) administered intramuscularly (IM) on Days 1 and 57, respectively (Main Study) and also to provide the heterologous 2-dose vaccination regimen (Ad26.ZEBOV on Day 1 and MVABN-Filo on Day 57) to participants in the control arm of the main study (Extension Phase).

The purpose of this study is to evaluate the safety and tolerability of MEDI8897 compared to palivizumab when administered to preterm infants entering their first RSV season and children with chronic lung disease (CLD) and congenital heart disease (CHD) entering their first and second RSV season.

The purpose of this study is to evaluate the safety, dose-requirements, and exploratory efficacy of twice-daily subcutaneous enoxaparin as venous thromboembolism prophylaxis in children (birth to 18 years) hospitalized with signs and/or symptoms of SARS-CoV-2 infection (i.e., COVID-19).

An open-label, single arm phase II study of the candidate Ebola Vaccine Ad26.ZEBOV/MVA-BN®-Filo

It is a single-center, randomized, open-label, phase IV study for the explorative investigation of the pharmacological mode-of-action of Echinaforce® extract in the form of Echinaforce® Chewable tablets"- Further, it is aimed to evaluate the effectiveness of the study product for the prevention and treatment of respiratory tract infections in generally healthy adults following a real-life setting. The study covers 2x2 + 1 month of prevention in 120 randomized participants following a tight sampling set-up for sensitive detection of viral infections by RT-qPCR analysis of nasal swabs and seroconversion of SARS-CoV2 IgG/IgM in serum samples.

This study is designed to test the efficacy and safety of combinations of two well-understood agents - famotidine and celecoxib in patients hospitalized with moderate-to-severe COVID-19 (based on World Health Organization [WHO] Ordinal Scale for Clinical Improvement). Both famotidine and celecoxib separately demonstrate clinical activity in mitigating COVID-19 disease symptoms or severity, and appear to have separate and complementary mechanisms of action.

This study will assess the safety, tolerability, and immunogenicity of VN-0200 after intramuscular injections in Japanese healthy adults and elderly subjects.

A phase 2, Randomized, Observer-blind, Multicenter, Dose-Ranging Study to Evaluate the Immunogenicity, Safety, and Tolerability of the plant-made H5 VLP Influenza vaccine adjuvanted with Alhydrogel or Glucopyranosyl-lipid adjuvant in squalene emulsion (GLA-SE), in healthy adults 18-60 years of age.
