COVID-19 Clinical Trials and Expanded Access

The data obtained from Covid-19 infections seem to suggest that the immunogenesis ofCovid-19 could in some cases be the result of immune dysregulation. On the other hand,endocrine damage is possible at the tile of Covid-19 infection (mainly thyroid,adrenal,and hypothalamus). These disorders are autoimmune or linked to degeneration.The main objective is to assess the thyroid function (thyrotropic axis) as well as thecorticotropic adrenal function of patients who have had Copvid-19 pneumonia. Thesecondary objectives is to describe the pathophysiological mechanisms of pulmonary andvasculothrombotic involvement of Covid-19

This study aims to determine how long COVID-19 neutralizing antibodies can be detected inan elderly institutionalized population presenting fragility factors.This study also aims to stratify seroconversion by immunological profiles of the elderlypatients residing in the EHPAD. This stratification requires the measurement ofimmunological marker levels already described in immunosenescence and also involved inthe development of certain chronic infectious diseases more common in the elderlypopulation. This analysis will enable the investigators to describe an immunological,clinical and biological profile representing a patient who has developed an immunityagainst COVID 19. It will also help the investigators to understand the differentmechanisms leading to a reduced immune response after a potential administration of avaccine. Finally, it will help describe the immune profiles of elderly residents whopresented with non-severe forms of COVID-19.

This is a pilot phase, open label, non-randomized study for the treatment of ARDS inpatients infected with COVID-19. Subjects will be enrolled and treated with one dose ofmesenchymal stem cells and follow-up will occur 90 days post-treatment.

This is a phase 1/2a study including 2 parts, phase 1 and phase 2a. The phase 1 part isan open-label, single-arm, dose-escalating study to evaluate the safety and explore thedose limiting toxicity and maximum tolerated dose of a human umbilical cord derivedmesenchymal stem cell product (BX-U001) in severe COVID-19 pneumonia patients with acuterespiratory distress syndrome (ARDS). Qualified subjects after the screening will bedivided into low, medium, or high dose groups to receive a single intravenous infusion ofBX-U001 at the dose of 0.5×10^6, 1.0×10^6, or 1.5×10^6 cells/kg of body weight,respectively. The Phase 2a part is a randomized, placebo-controlled, double-blindclinical trial examining the safety and biological effects of BX-U001 at the appropriatedose selected from phase 1 for severe COVID-19 pneumonia patients with the sameinclusion/exclusion criteria as the phase 1 part.

The purpose of this study is to assess the safety and tolerability of the investigationalproduct, SBI-101, in subjects with an infectious etiology of Acute Kidney Injury (AKI).SBI-101 is a biologic/device combination product designed to regulate inflammation andpromote repair of injured tissue using allogeneic human mesenchymal stromal cells.SBI-101 will be integrated into the renal replacement circuit and patients will betreated for up to 24 hours.

Since the 1960s, studies have shown that oral polio vaccine (OPV) may have beneficialnon-specific effects, reducing morbidity and mortality from other infections than polio.Such beneficial non-specific effect have been observed for other live vaccines, includingmeasles, smallpox and BCG vaccine. For BCG, the vaccine for which the mechanism has beenstudied the most, the effects appear to be mediated through the innate immune system. TheCOVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 has now caused over 7.1million cases and >400,000 deaths worldwide. As everywhere else, it is anticipated thatin Africa the older part of the population will be at risk of severe COVID-19. OPV iswidely used in Africa, but for children. Both polio and coronavirus are positive-strandRNA viruses, therefore it is likely that they may induce and be affected by common innateimmune mechanisms.In a randomised trial at the Bandim Health Project in Guinea-Bissau, the investigatorswill assess the effect of providing OPV vs no vaccine to 3400 persons above 50 years ofage. The trial will have the power to test the hypothesis that OPV reduces the combinedrisk of morbidity admission or death (composite outcome) by at least 28% over thesubsequent 6 months.

: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acuterespiratory syndrome coronavirus 2 (SARS-CoV-2). SAB Biotherapeutics has developedSAB-185, an Anti-SARS-CoV-2 Human Immunoglobulin Intravenous (transchromosomic [Tc]bovine-derived), as a potential therapeutic to treat COVID-19. This study will evaluatethe safety, immunogenicity, and pharmacokinetics of SAB-185 in ambulatory participantswith COVID-19.

This Phase 2/3 study is a multi-portion design to confirm that the chosen formulation anddosing regimen of CoVLP has an acceptable immunogenicity and safety profile.The Phase 3 portion is an event-driven, randomized, observer blinded, placebo-controlleddesign that will evaluate the efficacy and safety of the CoVLP formulation compared toplacebo.Subjects will be followed for safety and immunogenicity for a period of 12 months afterthe last vaccination.

This phase I trial evaluates the side effects and best dose of GEO-CM04S1 (previouslydesignated as COH04S1), a synthetic modified vaccinia Ankara (MVA)-based SARS-CoV-2vaccine, for the prevention of COVID-19 infection. COVID-19 infection is caused by theSARS-CoV-2 virus. SARS-CoV-2 has demonstrated the capability to spread rapidly, leadingto significant impacts on healthcare systems and causing societal disruption. GEO-CM04S1was created by placing small pieces of SARS-CoV-2 DNA (the chemical form of genes) intosynthetic MVA, which may be able to induce immunity (the ability to recognize and fightagainst an infection) to SARS-CoV-2. The purpose of the Phase 1 study is to determine thesafety and the optimal dose of the GEO-CM04S1 vaccine.The Phase 2 study is designed as a multi-center, double-blind, randomized, parallel,study to evaluate the safety profile of 2 dose levels of GEO-CM04S1 as a single boostershot to assess the immune response measured by the fold-increase in antibody againstSARS-CoV-2 Spike protein at day 28 post-injection among healthy adult volunteers.

The goal of this project is to rapidly screen promising agents, in the setting of anadaptive platform trial, for treatment of critically ill COVID-19 patients. In this phase2 platform design, agents will be identified with a signal suggesting a big impact onreducing mortality and the need for, as well as duration, of mechanical ventilation.
