Active clinical trials for "COVID-19"

The clinical syndrome associated with infection of the Coronavirus Disease 2019 (COVID-19) is notable for its variable clinical expression. Infection and transmission of the virus by asymptomatic individuals have been noted and represent one end of the clinical spectrum, while multi-organ failure, particularly pulmonary failure, and death represent the most severe end of the clinical spectrum. In a recent study published from the investigator's institution about the first 393 patients with COVID-19, 77.1% had a fever, a mechanism driven by IL-1. This suggests that there may be an excess release of IL-1 present. Cytokine storm syndrome (CSS) has been observed in patients with COVID-19 and has been proposed to contribute to the acute pulmonary failure that occurs. In distinct clinical settings, macrophage activation syndrome, elevated levels of pro-inflammatory cytokines, including IL-1, IL-6, and others, as well as elevations in laboratory indicators, including ferritin, CRP, d-dimer, and lymphopenia, have been observed. IL-1 production is induced in response to inflammatory stimuli and mediates various physiologic responses including inflammatory and immunological responses. Anakinra, a recombinant IL-1 receptor antagonist, has shown promise in treating CSS. It inhibits both IL-1-alpha and IL-1-beta. It is an FDA approved medication used in rheumatoid arthritis (RA) and Cryopyrin-Associated Periodic Syndromes (CAPS). Anakinra's ability to inhibit both IL-1 subtypes and short half-life makes it favorable to some experts. In the investigator's case-series, using anakinra in patients with COVID-19 showed promising in preventing the need for mechanical ventilation, and mortality subsequently. This study will determine the efficacy of anakinra, an interleukin (IL) -1 receptor blocker, in reducing the need for mechanical ventilation and/or 28-day mortality among patients with COVID-19 who have features of CSS and severe respiratory failure. The investigators will test the hypothesis that the proportion of subjects with COVID-19, features of CSS, and severe respiratory failure (World Health Organization (WHO) category 4 or 5) alive and without having required mechanical ventilation at day 28 from randomization will be 18% higher among those that receive anakinra compared to those that receive a placebo. A secondary hypothesis is that the number of subjects alive at 60-days will be higher amongst those who receive anakinra compared to those who receive a placebo.

The purpose of this double-blind, randomized, controlled study is to evaluate the efficacy, immunogenicity, reactogenicity and safety of an adjuvanted recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) trimeric spike (S)-protein subunit vaccine (SCB-2019) for the prevention of SARS-CoV-2-mediated COVID-19 in Participants Aged 12 Years and Older.

The current research is a pilot study to determine the feasibility of recruiting and retaining 40 participants diagnosed with COVID-19. The purpose is to observe the early use of fluoxetine (commonly known as Prozac) to reduce the severity of the COVID-19 illness. Fluoxetine is a drug that has been approved by the U.S. Food and Drug Administration (FDA) since 1987 for various mental health disorders.

This is a Phase 1b study to assess the safety and efficacy of COVI-MSC in treating post COVID-19 "long haulers" with pulmonary compromise.

This study is a multi-center and open design, phase Ⅳ clinical trial of an inactivated SARS-CoV-2 vaccine (CoronaVac) manufactured by Sinovac Research and Development Co., Ltd.The purpose of this study is to evaluate the safety of the SARS-CoV-2 Inactivated vaccine in population aged 18 years years and older and in people with pre-existing disease to provide reference for improving the immunization strategy of COVID-19 vaccine.

Antibodies are an important part of the body's defense against infection. Individuals who have no antibodies or very low antibody levels are considered less well protected from Coronavirus Disease 2019 (COVID-19) than those who have higher antibody levels. What level of antibodies is necessary for protection is currently unknown. Inadequate antibody response to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination has been described among kidney transplant recipients. The aim of this study is to elicit an antibody response to vaccination against SARS-CoV-2 in kidney transplant recipients who have failed to respond to two doses of either the Moderna COVID-19 vaccine or Pfizer-BioNTech Coronavirus Disease 2019 (COVID-19) vaccine.

This is an extension study to evaluate the safety, tolerability and immunogenicity of one booster dose of UB-612 COVID-19 vaccine in adults who completed two vaccinations of UB-612 vaccine 10, 30, and 100 μg in V-122 study.

This is a randomized, observer-blind, parallel-controlled study, for evaluation of safety and immunogenicity of sequential immunization of a recombinant COVID-19 vaccine (adenovirus type 5 vector) in Chinese healthy adults aged 60 and above after the priming vaccination of inactivated vaccine. 300 healthy subjects aged 60 and above will be recruited in this study. Of them, 200 subjects who have been vaccinated with two dose of inactive SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 3~6 months later. Other 100 subjects who have been vaccinated with one dose of inactivated SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 1~3 months later. The occurrence of adverse events within 28 days and serious adverse events within 6 months after vaccination will be observed. In addition, blood samples will be collected on day 0 before the boosting with ad5 vectored vaccine and on day 14, 28 and month 6 after the boosting. Serum antibody levels, cellular immune responses and the subgroups or germlines of the specific B cells will be analyzed. Each subject will remain in this study for approximately 6 months.

To develop an effective vaccine against the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, Clover Biopharmaceuticals is conducting a Phase 1 study (CLO-SCB-2019-001) in healthy volunteers to evaluate the safety and immunogenicity of SCB-2019, a recombinant SARS-CoV-2 trimeric Spike protein (S-protein) subunit vaccine. This study, CLO-SCB-2019-002, will be a long-term follow-up study for subjects who have completed CLO-SCB-2019-001 in order to assess longer safety and immunogenicity up to 24 months after the 1st dose of vaccination.
