NCT ID: NCT05184387 Completed - Influenza Clinical Trials

A Prospective Epidemiological Cohort Study Evaluating Occurrences of Influenza-like Illness.

Start date: December 1, 2021
Phase:
Study type: Observational

This Prospective epidemiological cohort study is being conducted in order to generate epidemiological data in support of Osivax's clinical development of a broad spectrum influenza vaccine based upon the internal influenza nucleoprotein (NP) as a target for immune response.

NCT ID: NCT05170009 Recruiting - Influenza Clinical Trials

Baloxavir in Combination With Oseltamivir in Allogenic Bone Marrow Transplant Recipients With Influenza

Start date: April 22, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This is a randomized, double-blind, placebo-controlled pilot study of the efficacy and safety of baloxavir in combination with oseltamivir (standard of care) for the treatment of influenza in allogeneic stem cell transplant patients. Although there are no data about this treatment option currently available, the investigator hypothesizes that combination therapy may be more effective in clearing influenza virus infection and decreasing the rate of emergence of resistant influenza in immunocompromised human hosts.

NCT ID: NCT05152017 Completed - Influenza Clinical Trials

The Objectives of This Study Are Study the Safety, Reactogenicity and Obtain Preliminary Data on the Immunogenicity of Flu-M Quadro, 4-valent Inactivated Split Influenza Vaccine, in Healthy Volunteers

Start date: November 16, 2019
Phase: Phase 1
Study type: Interventional

The study the safety, reactogenicity and obtain preliminary data on the immunogenicity of Flu-M Quadro, 4-valent inactivated split influenza vaccine, in healthy volunteers

NCT ID: NCT05144464 Enrolling by invitation - Influenza Clinical Trials

A Clinical Trial of an Inactivated Quadrivalent Influenza Vaccine in Chinese Children Aged 3 to 8 Years

Start date: September 19, 2021
Phase: Phase 4
Study type: Interventional

Routine annual influenza vaccination is recommended for all persons aged ≥6 months who do not have contraindications. For those aged 6 months through 8 years who have previously received ≥2 total doses of trivalent or quadrivalent influenza vaccine ≥4 weeks apart, they require only 1 dose of influenza vaccine. For those who have not previously received ≥2 doses of trivalent or quadrivalent influenza vaccine, they require 2 dose of influenza vaccine. but the evidence on how to select vaccine doses for quadrivalent influenza vaccine is limited in China. The study is a prospective, open-label comparison of the immunogenicity and reactogenicity of 1 versus 2 doses of an inactivated quadrivalent influenza vaccine in subjects of 3-8 years old with different history of influenza vaccination.

NCT ID: NCT05126979 Completed - Influenza Clinical Trials

The Objectives of This Study Are Study of the Reactogenicity, Safety and Immunogenicity of Flu-M Inactivated Split Influenza Vaccine in Volunteers Aged 18-60 Years

Start date: March 9, 2016
Phase: Phase 1
Study type: Interventional

Study of the Reactogenicity, Safety and Immunogenicity of Flu-M Inactivated Split Influenza Vaccine in Volunteers Aged 18-60 Years

NCT ID: NCT05095844 Recruiting - COVID-19 Clinical Trials

National Vaccine Adverse Event Reporting Survey and Etiology

NVAERS
Start date: March 15, 2022
Phase:
Study type: Observational

If your serious vaccine-induced adverse event has been entered in the CDC Vaccine Adverse Event Reporting System (VAERS) we are interested in enrolling you for this study in order to log your symptoms. The primary goal of this study is to create a national database and gather vaccine-associated serious adverse events/injury data from newly vaccinated individuals in the US in order to identify the possible underlying causal relationships and plausible underlying biological mechanisms. The project aims to identify the genetic determinants of vaccine-induced adverse response by studying host genetics. We plan to use whole genome sequencing to identify single nucleotide polymorphisms associated with cardiovascular, neurological, gastrointestinal, musculoskeletal and immunological symptoms induced by vaccine administration. The secondary goal is to establish criteria that enable classification of vaccine-induced adverse events/injuries compare data from our database with the official Vaccine Injury Table National Vaccine Injury Compensation Program on or after March 21, 2017. The tertiary goal is to establish a database to gather detailed long-term adverse reaction data from subjects enrolled in FDA Emergency Use Authorized vaccine clinical trials.

NCT ID: NCT05095545 Completed - Influenza Clinical Trials

Dose Range Study to Evaluate the Efficacy and Safety of AV5080 in Patients With Influenza

Start date: November 13, 2017
Phase: Phase 2
Study type: Interventional

Assessment of the effect reached with the different doses of AV5080 on the duration and severity of influenza symptoms based on the incidence of their resolution within 96 hours from study treatment initiation compared to Placebo. The absence of influenza symptoms or their reduction to mild severity for at least 24 hours indicates the resolution of influenza.

NCT ID: NCT05093998 Not yet recruiting - Influenza Clinical Trials

Study Evaluating the Efficacy and Safety of AV5080 in Patients With Uncomplicated Influenza

Start date: January 15, 2022
Phase: Phase 3
Study type: Interventional

To evaluate the efficacy of AV5080 versus Placebo based on time to symptom resolution in patients with uncomplicated influenza.

NCT ID: NCT05089123 Completed - Influenza Clinical Trials

The Objectives of This Study Are Study the Immunogenicity and Safety of the Flu-M [Inactivated Split Influenza Vaccine], vs. the Ultrix® Inactivated Split Influenza Vaccine, in Volunteers Who Are Over 60 Years Old

Start date: March 3, 2020
Phase: Phase 3
Study type: Interventional

This trial by its design was a prospective, multicenter, double blind, randomized comparative clinical trial of the IIIb-IV phase which was carried out in parallel groups of volunteers over the age of 60

NCT ID: NCT05087355 Completed - Influenza Clinical Trials

Health Status Prior and Post Infection With Influenza or COVID 19: a Population Based Retrospective Analysis of 2016-2021

Start date: January 1, 2016
Phase:
Study type: Observational

The overall project aim is to study outcomes after COVID-19 and influenza hospitalisation from 2016 - 2021 by retrieving data from the main social security carriers in Austria for the years 2010-2018
