COVID-19 Clinical Trials and Expanded Access

Prospective assay for SARS-CoV-2 antibody detection indirectly by immunofluorescence: SARS-CoV2 IIF method

The emergence and rapid spread of the coronavirus disease 2019 (COVID-19) since December 2019 across 188 countries globally has become a major public health crisis. COVID-19 was declared a pandemic by the World Health Organisation (WHO) on the 11th March 2020. To date, more than 14,000,000 cases and 600,000 deaths have been reported. COVID-19 is an acute respiratory disease caused by the novel SARS-CoV-2 virus from the Betacoronavirus genus, just like SARS-CoV and MERS-CoV. SARS-CoV-2 is primarily transmitted person-to-person through respiratory droplets or close contact. Fomite transmission has also been implicated as a transmission route. Common respiratory symptoms such as fever, sore throat, cough and shortness of breath, may appear 2 - 14 days after exposure. About 20% of infected cases progress to severe disease resulting in an estimated 2 - 5% mortality reported. With the unrelenting increase in cases being reported worldwide, there is thus an urgent need for therapeutics to be developed and used to disrupt the ongoing pandemic. To date, there is no specific proven antiviral treatment for COVID-19. Supportive care is recommended for symptom relief and for severe cases, organ support is critical for optimal outcome. Numerous vaccine candidates against SARS-CoV-2 are under development and a couple have entered Phase 1 clinical trials. Remdesivir, a nucleotide analog, developed by Gilead Sciences as a treatment for Ebola virus disease is currently being repurposed and undergoing multiple clinical trials to evaluate safety and efficacy in COVID-19 patients. In a preliminary study, convalescent plasma containing neutralizing antibodies against SARS-CoV-2 has also been experimentally administered in critically ill COVID-19 patients with promising results. Donor plasma used was rich in virus specific IgG and IgM antibodies as determined by ELISA. Within days of convalescent plasma treatment, patients showed decrease in viral load (via qRT-PCR), as well as improved clinical status being observed. Tychan's TY027 will be the first biologics in the world, specifically targeting SARS-CoV-2, to enter human clinical trials. It is anticipated that a SARS-COV-2 specific monoclonal antibody therapeutic administered to acutely infected patients could reduce disease severity as well as prevent transmission by reducing viral load and viral shedding. It could also be used as prophylaxis against COVID-19 amongst high risk contacts.

France and especially the region "Grand Est" have been damaged by the COVID-19 pandemic. This pandemic resulted in a reorganization of the hospitalization sectors. In order to better understand the disease, the investigators wish to carry out a descriptive analysis of hospitalized patient data. This study would notably allow us to identify some prognostic factors. The main objective of this study is to identify individual factors that are associated with a poor prognosis (with ICU admission or death).

This is a randomized, double-blind, placebo-controlled, in which one dose of nangibotide will be tested versus placebo. All patients with a diagnosis of COVID-19, and a requirement for respiratory support will be considered for study participation. The applicable local requirements for informed consent will be followed. Where permissible, an emergency consent procedure will be followed for patients unable to provide consent by themselves. All potential study patients will receive standard of care treatment throughout the study. Patients will receive a continuous intravenous (i.v.) infusion of nangibotide at 1.0 mg/kg/h or a matching placebo. Treatment with study drug must be initiated as early as possible but no later than 48 hours after the initiation of ventilatory support (Patients will be treated for 5 days or until discharge from critical care, whichever is sooner). Follow-up visits will be performed on days 8 and 14. The end of study visit is at day 28. A further follow up visit will be undertaken on day 60.

Understanding the SARS-Cov2 epidemic is a major public health issue, both in the community and in the hospital sector. Because of their central position in the management of patients infected with COVID-19, hospital staff may be considered at high risk of infection. The development of serological tests makes it possible to reliably document a contamination, symptomatic or not, that is more than 3 weeks old. These tests, combined with clinical questioning of the symptoms, make it possible to determine the proportion of asymptomatic infections whose impact in the transmission of this disease appears to be major. The duration of the presence of the antibodies that are hoped to neutralize after infection with CoV2-SARS remains uncertain. Documenting the evolution of antibody levels and their monitoring in a population at high risk of re-exposure to CoV2-SARS is a major issue in understanding this disease and in assessing the risk of infection among healthcare workers.

The disease caused by the new coronavirus, SARS-CoV-2, called COVID-19, it has considered a worldwide pandemia by the WHO. Suddently, it produces a lot of patients severe ill, in a little geographic area, that could surpase the resourses of the any health system in the world. There is no documentation of an effective alternative for the treatment of the severe ill patients, that can reduce the mortality or the adverse events suffered by these people. It is has suggested the usefulness of the Mesenchymal Stem cells (MSC) for the management of these patients, thanks to their direct and indirect antiviral capacity, and its potency as immunomodulator, that could ameliorate the lung disease and the severity of COVID-19.

The primary objective is to assess the impact of hydroxychloroquine in hospitalized patients with COVID-19 and risk factors for severe/critical disease.

Ivermectin which is an FDA-approved broad spectrum anti-parasitic agent, has also anti-viral activity. In vitro study have shown its activity against SARS-CoV-2, however its clinical effect on patients with COVID-19 never been tested. In this RCT we would like to evaluate the effect of Ivermectin on reduction of viral shedding among mild to moderate COVID-19 patients, and in shortening the symptom resolution time.

This a phase II, proof-of-concept study. In the present study, we investigate if the administration of blood-plasma from patients recovered from COVID-19, could be effective to treat patients who are severely ill because of a COVID-19 infection. The general idea behind the transfusion, is that plasma of recovered patients contains antibodies that could eliminate the novel coronavirus causing COVID-19, and lead to a less severe course of the disease, or a faster healing. Simply put, in this study we would like to investigate whether 'borrowed immunity' from a person who has cured from this disease, could be applied to cure other patients more rapidly.

To limit the pandemic Covid-19 infection, the French government imposed a closure of all Intensive Care Unit (ICU). The family's visitations are prohibited during active Covid -19 pandemic in 2020 and in 2021. This restrictive visit policy could result in an increase in symptoms of anxiety, depression or post-traumatic stress disorder for relatives of ICU patients. The aim of this study is to compare symptoms of anxiety, depression or post-traumatic stress for relatives of ICU patients during Covid period with those during no Covid period (2020 and 2021) with those no Covid period (2022)
