COVID-19 Clinical Trials and Expanded Access

The purpose of this study is to assess the efficacy and safety of chloroquine prophylaxis on the incidence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infections in healthcare workers exposed to patients with confirmed Coronavirus Disease 2019 (COVID-19)

This is a Phase 1, open-label study to evaluate the safety profile of CORVax +/- pIL-12, (electroporated SARS-CoV-2 spike (S) protein plasmid DNA vaccine with or without the combination of electroporated IL-12p70 plasmid.

The primary objective of this study is to evaluate the efficacy of CKD-314 (Nafabelltan) compared to standard of care (SOC), with respect to clinical status assessed by a 7-point ordinal scale in hospitalized adult patients diagnosed with COVID-19 pneumonia

This multicentre prospective study will enroll a sufficient number of patients to afford approximately 30 positives and > 30 negatives (as determined by the SOC - Comparator method) in the United States and/or Canada. One to three sites in the Canada will participate over an approximate 6-week enrolment period. The actual enrolment period will be dependent upon prevalence of Covid-19, and site set up. Once positives sample size is achieved, expected SARC-CoV-2 negative subjects will be permitted. Once subjects are consented and recruited for the study, up to three (3) study-specific nasopharyngeal samples for each patient will be collected by trained operators at the clinical site: a single SOC swab, and two (2) Spartan swabs where the second swab is optional and used when the first Spartan swab test does not produce a positive or negative result ("inconclusive"). The first swab sample will be tested at the clinical site according to standard of care protocols currently in place for the sites' nasopharyngeal swab-based SARS-CoV-2 RT-PCR testing. The second nasopharyngeal sample will be tested at the site using the Spartan COVID-19 v2 System. A third, optional nasopharyngeal sample, if collected, will be tested using the Spartan COVID-19 v2 System only when the test conducted with the second nasopharyngeal swab does not produce a positive or negative result.

This is a phase I/II clinical trial using adoptive cell therapy with NK cells or memory T cells in patients affected by COVID-19. Severe cases with COVID-19 present a dysregulated immune system with T cell lymphopenia, specially NK cells and memory T cells, and a hyper-inflammatory state. This clinical trial proposes the use of cell therapy for the treatment of patients with worse prognosis due to SARS-CoV-2 infection (those with pneumonia and/or lymphopenia). This is an innovative and a non-pharmacological intervention.

Background: COVID-19 is a new disease caused by SARS-CoV-2 that was identified in 2019. Some people who get sick with COVID-19 become ill requiring hospitalization. There are some medicines that may help with recovery. Researchers want to see if a drug called fostamatinib may help people who are hospitalized with COVID-19. Objective: To learn if fostamatinib is safe in patients who are hospitalized with COVID-19 and gain earlier insight into whether it improves outcomes. Eligibility: Adults age 18 and older who are hospitalized with COVID-19. Design: Participants will be screened with a physical exam, including vital signs and weight. They will have a blood test and chest x-ray. They will have a COVID-19 test as a swab of either the back of the throat or the back of the nose. They will take a pregnancy test if needed. Participants will be randomly assigned, to take either fostamatinib pills or a placebo twice daily for up to 14 days in addition to standard of care for COVID-19. If they can swallow, they will take the pills by mouth with water. If they cannot swallow or are on mechanical ventilation, the pills will be crushed, mixed with water, and given through a tube placed through the nostril, or placed in the mouth, down the esophagus, and into the stomach. Blood samples will be taken daily. Participants will return to the Clinical Center for safety follow-up visits. At these visits, they will have a physical exam and blood tests. If they cannot visit the Clinical Center, they will be contacted by phone or have a telehealth visit. Participation will last for about two months

The purpose of this study is to investigate if Quercetin Phytosome is beneficial for the treatment of COVID-19.

CORONAVIT is an open-label, phase 3, randomised clinical trial testing whether implementation of a test-and-treat approach to correction of sub-optimal vitamin D status results in reduced risk and/or severity of COVID-19 and other acute respiratory infections.

Evaluating the efficacy of Tocilizumab in hospitalized patients in the inflammatory phase of COVID-19. Randomization 2:1 (TCZ:standard of care).

The purpose of this study is to measure immunity to the flu vaccine over time in patients who had COVID-19. Adults who have been diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.
