Active clinical trials for "COVID-19"

This is a 2-Stage, Phase III, randomized, active-controlled, observer-blind, parallel-group, multi-center study to compare the immunogenicity and safety of SK SARS-CoV-2 recombinant nanoparticle vaccine adjuvanted with AS03 (GBP510) to ChAdOx1-S in adults aged 18 years and older.

The project is essential to understand the impact of the COVID-19 pandemic in patients with Chronic Liver Disease (CLD). The impact has been felt due to direct risk of COVID infection in self, or in caregivers, lack of access to services during lockdown, interruptions in transplant listing and waitlist mortality. Briefly, the following points will be focused during the study. Long haul COVID-19 related symptoms. Impact on health and delay in interventions or drug therapy due to interruption of physical outpatient services. Impact on emergency admissions due to refractory ascites, new decompensation, variceal bleeding etc Impact on delayed transplant listing and waitlist mortality Impact on post-transplant patients with lack of access to drug monitoring/ physical OPD Impact on delay in interventions due to hepatobiliary malignancy. Effects of COVID-19 infection, vaccination (single dose, two doses) and no vaccination and protective antibody levels in patients with chronic liver disease and post-transplant recipients. Determination of dose protocol and need for booster vaccination in patients with CLD and post liver transplant recipients.

This is a Phase I/II trial to evaluate the safety and efficacy of intravenous (IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles (EV), ExoFlo, as treatment for Post-Acute COVID-19 and Chronic Post-COVID-19 syndrome.

A Randomized, Double Blind, Positive Control Clinical Study to Evaluate the Immunogenicity and Safety of Sequential Immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) Against COVID-19 in Healthy Adults Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines

DESIGN Longitudinal prospective observational multicentre study. Primary objective: Understand the immune mechanisms driving COVID-19 disease in patients with a history of lung disease

The aim of the study is to clinically use bovine Lf as a safe antiviral adjuvant for treatment and to assess the potential in reducing mortality and morbidity rates in COVID-19 patients. The study was approved by the ethical committee of the Egyptian Center for Research and Regenerative Medicine in 11-5-2020.

The primary objective of the study is to evaluate cardiac and pulmonary hemodynamic changes over time as predictor of disease progression and outcome in COVID-19 patients admitted to ICU. The primary endpoint is the occurrence of a major event predefined as either: death (all-cause mortality) or discharge from ICU (limit of 4 months). This is a uni-center prospective observational cohort study with an inclusion period of 2 months. The end of the study is foreseen in 6 months.

Background: People who get infected with COVID-19 have an unpredictable risk to worsen and die. This makes it hard to decide who can quarantine at home and who should be treated at a hospital. Researchers think the risk may be related to how a person s B and T cells respond to the virus. B and T cells are the major components of a person s immune response. B and T cells responding to the virus with a favorable pattern may lead to recovery, and this favorable pattern may be helpful to establish. If people in a vaccine trial get this same favorable pattern when responding to a vaccine, this may be a useful early signal that the vaccine will be successful. Objective: To examine how immune cells respond to COVID-19 infection. Eligibility: Adults ages 18 and older who have a confirmed or suspected COVID-19 infection or had COVID-19 in the past. Also, healthy donors with no suspected COVID-19 infection Design: Participants will be screened with medical record review. Participants will be tested with a research assay to determine who was infected with COVID-19 and who was not. This test will be used to understand research results, not to advise patients. Participants with active infection must be isolated, usually in a hospital. Other participants may give blood samples at NIH or at their local doctor s office or lab. Participants may give blood samples up to three times a week for a total of ten times, and may also give blood samples after starting a vaccine trial. Participants will be contacted by phone or email every 2 months for up to 2 years.

The aim of the study is to access the efficacy and safety of acupuncture for post COVID-19 fatigue.

To investigate whether treatment with Azvudine reduces the risk of severe illness or death in patients who are at a potential risk of progressing to severe COVID-19 infection.
