Active clinical trials for "COVID-19"

This phase 1 trial aims to assess the safety and tolerability of two doses of ABNCoV2, formulated with and without the adjuvant MF59, in healthy adult volunteers and to identify the dosage and formulation that optimizes the immunogenicity-tolerability ratio 14 days following first vaccination with ABNCoV2.

This study is a double-blind, randomized phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine (CoronaVac）manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the lot-to-lot consistency, immunogenicity and safety of CoronaVac in healthy adults aged 26-45 years.

Hydrogen peroxide is produced physiologically by oral bacteria and plays a significant role in the balance of oral microecology since it is an important antimicrobial agent. In the epithelial cells, the enzyme superoxide dismutase catalyzes a reaction leading from hydrogen peroxide to the ion superoxide. The induced oxidative stress stimulates a local innate response via activation of the toll-like receptors and the NF-κB. Those kinds of reactions are also activated by viral infections. Virus-induced oxidative stress plays an important role in the regulation of the host immune system and the specific oxidant-sensitive pathway is one of the effective strategies against viral infections. Therefore, nose/mouth/throat washing with hydrogen peroxide may enhance those local innate responses to viral infections. The investigators hypothesised that a treatment with a mouth wash and a nasal spray containing a diluted solution of hydrogen peroxide may accelerate the negativisation rate of a positive PCR swab test for SARS-CoV-2 (COVID-19).

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.

The purpose of this study is to assess the efficacy and safety of Proxalutamide as a treatment for COVID-19 patients in the intensive care unit

This is a randomized phase IV dose-optimization study evaluating the safety and immunogenicity of two doses of COVID-19 mRNA vaccines being authorized in the European Union since December 2020: Vaccine BNT162b2 (Comirnaty®; Pfizer-BioNTech) in healthy adults up to age 55 year. Immunogenicity will be measured 28 days after first and second dose, and day 180 and day 365 after first vaccination of 20 and 30 mcg of BNT162b2. The primary outcome is the level of binding antibodies for RBD 28 days after the second dose.

Novel Coronavirus is defined to be the cause of COVID-19, recently. It's known that COVID-19 goes with excessive immune reaction of human body in severe cases. The investigators hypothesize that quercetin, as a strong scavenger and anti-inflammatory agent, can be effective on both prophylaxis and treatment of COVID-19 cases. Therefore, the aim of this study to evaluate the possible role of quercetin on prophylaxis and treatment of COVID-19.

This is a multicentered, open-label, randomized controlled Phase 2 trial to evaluate the safety and efficacy of providing human coronavirus-immune convalescent plasma as treatment for COVID-19 disease in hospitalized children in the context of the COVID-19 pandemic.

COVID-19 was declared a pandemic on March 11th. Efforts to save lives are essential as we will face increasing morbidity with rising demands on health care resources. Since pregnant women with COVID-19 have systematically been excluded from drug trials, potential treatment options for these high-risk individuals remain untested. The aim of our trial is to determine whether hydroxychloroquine given to COVID-19 positive pregnant women can reduce COVID-19-related hospital admissions, thereby allowing women to stay at home while limiting utilization of hospital resources and resulting exposure of health care providers.

Clinical manifestations of Covid-19 are poorly characterised in HIV co-infection, which may predispose to more severe disease. Reducing hospitalisation and severe illness in this population has important individual and public health benefits. The investigators propose a pragmatic multi-centre, randomized controlled trial in South Africa to evaluate the efficacy and safety of chloroquine or hydroxychloroquine to prevent progression of disease and hospitalisation amongst HIV-positive people with Covid-19 not requiring hospitalisation at initial assessment.
