Active clinical trials for "Infections"

Gut microbiome manipulation to alter the gut-lung axis may potentially protect humans against respiratory infections. However, clinical trials of synbiotics, one of the microbiota-targeted intervention, in this regard is few. Therefore, this study aims to examine the effect of synbiotics on the incidence and severity of upper respiratory tract infection, gut microbiota composition and function, as well as biomarkers of immune function.

To assess the effectiveness of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing and treatment during pregnancy to reduce adverse pregnancy and birth outcomes compared to the standard of care (treatment based on symptoms and signs).

It is known that the pretreatment with exogenous interferon blocks SARS-CoV-2 infection, but intervention is much more effective if administered prior to infection. In this study the primary aim is to investigate 28-day regime of nasal interferon gama use in healthy participants for COVID-19 and other respiratory infections prevention.

This study is designed to assess the safety and efficacy of Rosmalip® nutritional supplement compared to placebo in subjects with solid cancer for the prevention of infections including COVID-19.

The purpose of the study is to investigate the safety and immunogenicity of the Ad26.RSV.preF based vaccine in adults 18 to 59 years of age who are healthy or at risk for severe Respiratory Syncytial Virus (RSV) disease, compared to adults 65 years and above.

This is a randomized, double-blinded, Phase 3, multi-center trial of the clinical and microbiologic response of patients with a respiratory tract infection (RTI) due to coronavirus treated with a combination of azithromycin and hydroxychloroquine. Approximately 200 patients with symptoms of an RTI who test positive for SARS-CoV-2 by polymerase chain reaction (PCR) will receive a combination of azithromycin 500 mg and hydroxychloroquine 600 mg or matching placebos for six consecutive days. There will be two treatment regimens into which patients are randomized so that all patients will receive some active therapy.

This is a Phase 2 single-center, open-label, single-arm, study of a microbiological endpoint using antimicrobial photodynamic therapy (aPDT) for nasal disinfection in all patients (universal) presenting for surgery at an acute care hospital for a wide range of surgical procedures.

This is a Phase 2, randomized, placebo-controlled, double-blind, proof-of-concept study of intranasal foralumab in hospitalized subjects with severe COVID-19 and pulmonary inflammation. Foralumab is a fully human second generation anti-CD3 mAb with a modified Fc unit (two amino acid substitutions) composed of 2 heavy chains with an immunoglobulin (Ig) G1constant region and 2 light chains with a kappa constant region. In a separate Phase 2 randomized, controlled, pilot trial conducted to assess safety, tolerability, and efficacy in 39 patients with mild to moderate COVID-19 in Brazil, showed that intranasal foralumab may be of benefit in modulating immune reactivity and in reducing pulmonary inflammation. Importantly, intranasal administration of foralumab was well tolerated with no clinically significant changes in blood cell counts (including blood lymphocytes), no evidence of hypersensitivity, and no serious adverse events (SAEs) were reported in the study.

The purpose of this study is to assess SARS CoV-2 infection, viral shedding, and subsequent potential transmission in individuals immunized with the Moderna COVID-19 vaccine.

This is a dose optimisation study in healthy adults aged 18-30 who will be experimentally inoculated with SARS-CoV-2. The aim is to cause PCR-confirmed upper respiratory infection in the majority of challenged individuals with minimal or no illness, providing data on the course of COVID-19 and the immune response to SARS-CoV-2 infection. This will establish an optimised dose and study design that will then be used to evaluate the efficacy of treatment and vaccine candidates plus level and duration of immune protection in follow-on trials.
