Active clinical trials for "Respiratory Tract Diseases"

The purpose of this open label, randomized, study is to obtain information on the safety and efficacy of 80 ppm Nitric Oxide given in addition to the standard of care of patients with COVID-19 caused by SARS-CoV-2.

The purpose of this study is to assess the safety, reactogenicity and immunogenicity of the investigational GSK Biologicals' GSK3277511A vaccine in adults

This Phase 2 Quadrivalent VLP Vaccine study is intended to replicate and extend the immunogenicity and safety results obtained in earlier Phase 1-2 and Phase 2 studies. The study is being conducted to demonstrate that the immunogenicity profile of the Quadrivalent VLP Vaccine meets the US Center for Biologics Evaluation and Research (CBER) licensure criteria. The study will also help to define the optimal dose, establish potential competitive advantages, and support the design of future studies.

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)

Pre-hospital emergency health workers, who are on the front line among healthcare workers, are at greater risk in epidemic situations, as they are the first team to come into contact with the patient and are responsible for making necessary interventions by staying in close contact with the patient during the transfer process (1, 2). Health workers need to improve their knowledge, attitudes and skills during the pandemic process; on the other hand, they experience mental and communicative problems more strikingly. It is essential to increase the continuity of development, mental resilience, and communication of healthcare professionals(3). A randomised controlled study was planned to prepare a training program to improve pre-hospital emergency health workers' knowledge, attitudes, and skills about pandemic preparations and evaluate its effectiveness. The intervention study was conducted among pre-hospital emergency health workers in Eskişehir between July 2020 and December 2021. Ethics committee approval and administrative permissions were obtained. In the study, when the type 1 (α) error was 5%, and the type 2 error (1-β) was 95%, the effect size was accepted as 0.5, and it was calculated with the G*Power 3.1 statistical program that there should be at least 47 people in the groups. The study population consists of paramedics and emergency medical technicians(EMT) (N=420) in Eskişehir city, Turkey. Each participant in the study population was given a score by propensity score matching analysis according to age, gender, occupational group (paramedic and EMT), working time (year) variables. The study list was arranged according to the initials of their surnames, and the drawing method was used while assigning those with similar scores to four groups (experimental 1, experimental 2, control 1, control 2). Four groups, two interventions and two controls, were included in the study. The work consisted of five stages: Determining the needs in education, Development of educational materials, Making pre-training measurements, Implementation of the training program, Performing post-training measurements. As a result of the evaluation, the subjects that healthcare professionals need to train were determined as knowledge, attitude, skills, infection control measures, communication skills, psychological resilience and attitudes of healthcare professionals to the patient in a simulated case and pandemic. The appropriate data collection form was chosen after the training program's content was determined. Before the intervention, the first measurements were taken via the COVID-19 knowledge, attitude, skills, and perceived barriers to infection control questionnaire, the communication competence scale, the psychological resilience scale, and the data collection form, including the simulated case approach. After the training program's content was determined, training was given to the intervention group with a video screening and the control group with the classical training method. After the training program, a post-test was applied after a four-week follow-up.

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.

The purpose of this open label, 2-phase, study is to obtain information on the safety of 80 ppm and the safety and efficacy of 150 ppm Nitric Oxide given in addition to the standard of care of patients with COVID-19 caused by SARS-CoV-2.

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.

A phase I/II trial conducted in a single centre, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of a single intramuscular injection of plant-based Seasonal Quadrivalent VLP Influenza Vaccine administered to healthy adults 18-49 years of age. A total of one hundred and twenty (120) subjects will be randomized in four (4) groups of 30 subjects to receive one injection of either a low, a medium, or a high dose level of VLP of the quadrivalent VLP influenza vaccine or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80).

The main purpose of the study is to see how safe GSK1995057 is and how well it is tolerated after dosing. The study will also investigate how GSK1995057 is taken up, metabolised (chemically broken down), distributed through the body and excreted, and what some of the effects of the study drug are.
