Active clinical trials for "COVID-19"

In this phase 1 study, the inactivated virus vaccine National Research Centre (NRC) Vaccine-101 (VACC-101) will be investigated for its safety and immunogenicity in healthy volunteers with the aim of providing effective and safe protection against COVID-19.

This project capitalizes on a natural experiment imposed by the COVID-19 pandemic in conjunction with an extensive set of cognitive, emotional, biological, and neuroimaging variables already collected at multiple time points in older adults participating in a clinical trial of exercise and mindfulness. This project will elucidate the effects of stress on cognitive function and emotional health in later life, including biological measures of Alzheimer Disease risk, stress, and aging, with the ultimate goal of discovering how to mitigate these effects, among older adults who have made and maintained a lifestyle change.

This study aims to assess cerebral autoregulation by near-infrared spectroscopy (NIRS) in patients with severe coronavirus disease 19 (COVID-19). Results on COVID-19 participants will be compared with prior results of patients with septic shock and cardiac arrest, who participated in NCT03649633 and NCT02790788, respectively.

A Phase II/III Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Azvudine in Preventing SARS-Cov-2 Infection in Household Contacts of Individuals Infected with SARS-CoV-2

A phase III, randomized, observer-blind, active-controlled, parallel-group, multi-center study to evaluate immunogenicity and safety of a preventive COVID-19 vaccine EuCorVac-19 in healthy adults aged 18 years and older

This clinical trial is designed to assess the safety, tolerability and immunogenicity of a single dose of ChulaCov19 BNA159 and ChulaCov19 BNA159.2 vaccines as a booster dose, given at least 3 months after receipt of a previous booster dose of any authorized/approved COVID-19 vaccine.

The objective of this study is to evaluate the safety, tolerability, and immunogenicity of SCTV01C in healthy population aged ≥18 years previously vaccinated with inactivated COVID-19 vaccine.

A cluster randomized trial will be conducted to evaluate the difference between an Acteev™ system (Acteev™ N95 masks YQD8008 during shifts+ Acteev™ fabric masks in community) and a standard system (standard N95 masks during shifts+ fabric masks in community) in preventing Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2)in healthcare workers(HCWs).

To evaluate the effectiveness of the single dose Ad26.COV2.S COVID-19 vaccine plus a homologous boostwith Ad26.COV2.S COVID-19 vaccine among Sisonke participants as compared to unboosted Sisonkeparticipants; vaccinated; and unvaccinated populations in South Africa

The researchers will recruit volunteers from various organisations who are willing and able to be randomised to either working from home for 4 weeks followed by working in the office for 4 weeks, or vice versa. The goal is to assess whether working from home has an impact on the risk of symptoms of respiratory infection.
