COVID-19 Clinical Trials and Expanded Access

This study will assess the safety and immunogenicity of AG0301-COVID19 in healthy adult volunteers.

This Phase 1 single-dose, dose-escalation study is an open label trial evaluating the safety of CPI-006, a humanized monoclonal antibody targeting the CD73 cell-surface ectonucleotidase, as immunotherapy for stable hospitalized mild or moderately symptomatic COVID-19 patients with a parallel non-randomized Control Arm for treatment with standard of care only.

In recent months, a new coronavirus, SARS-CoV-2, has been identified as the cause of a serious lung infection named COVID-19 by the World Health Organization. This virus has spread rapidly among the nations of the world and it is the cause of a pandemic and a global health emergency. There is still very little scientific evidence on the virus, however epidemiological data suggest that one of the most frequent comorbidities is diabetes, along with hypertension and heart disease. There is no scientific evidence on the possible effects of this infection on the function of the β cell and on glycemic control. Clinical evidence seems to suggest that COVID-19 infection mostly affects the respiratory system, and an acute worsening of glycemic compensation is not described as generally observed in bacterial pneumonia. However, previous work on acute respiratory syndromes (SARS) caused by similar coronaviruses, had described that the infection has multi-organ involvement related to the expression of the SARS coronavirus receptor, the angiotensin 2 converting enzyme, in different organs, especially at the level of endocrine pancreatic tissue. In the population of this previous work, glucose intolerance and fasting hyperglycaemia have been described and in 37 of 39 diabetic patients examined, a remission of diabetes was observed three years after the infection. It is possible that the coronaviruses responsible for SARS may enter the pancreatic islets using the angiotensin 2 converting enzyme receptor, expressed at the level of the endocrine pancreas, thus causing diabetes. Additionally, previous literature on coronavirus infections (SARS and MERS or Middle-East Respiratory Syndrome) suggested that diabetes could worsen the evolution of the disease. In particular, in case of Middle-East Respiratory Syndrome-CoV infection, diabetic mice had a more prolonged serious illness and a delay in recovery regardless of the viremic titer. This could probably be due to a dysregulation of the immune response, which results in more serious and prolonged lung disease. There are currently no data on pancreatic beta cell function in patients with COVID-19.

The purpose of this prospective, Phase 2, multicenter, blinded, randomized placebo controlled study is to demonstrate that early treatment with mavrilimumab prevents progression of respiratory failure in patients with severe COVID-19 pneumonia and clinical and biological features of hyper-inflammation.

Epidemiological data have related particulate matter (PM), nitrogen dioxide (NO2) and ozone (O3) to COVID-19 morbidity and mortality at the population level. Air pollution may be related to an increase in the COVID-19 severity and lethality through its impact on chronic diseases such as cardiovascular and respiratory diseases and diabetes that are also the main comorbidities associated with COVID-19. Epidemiological studies using individual data are needed to provide more precise estimate of the association between air pollution exposure and COVID-19. In this multicenter prospective study, the investigators will analyze the number of deaths in COVID-19 confirmed cases in geriatric patients according to long-term exposure to air pollution, taking into account confounders such as diabetes, hypertension, age, and BMI. Exposure to air pollution will be estimated as the mean concentration of air pollutants at the residential address during the previous two years. In addition, the investigators will explore the relationship between short-term variations in air pollutants, relative humidity, temperature, UV radiations, pollen and the occurrence of COVID-19.

This study is a Phase 2b, Multicenter, Open-label, Randomized, Comparator- Controlled Study to Evaluate the Efficacy and Safety of Desidustat Tablet for the Management of mild, moderate and severe COVID-19 patients. 100 mg of Desidustat will be administered for a period of 14 days along with recommended standard care during the trial.

Impacts of the Covid-19 epidemic and associated lockdown measures on the management, health and behaviors of cystic fibrosis patients during the 2020 epidemic

This project will evaluate the benefit of an automated home symptom monitoring system, Symptom Care at Home, to track COVID-19 symptoms, provide instructions to reduce COVID-19 exposure, and reduce cancer symptom severity during the COVID-19 pandemic. The investigators will determine if Symptom Care at Home decreases the need for cancer patients to use emergency departments and hospitalization for cancer symptom care. The project addresses the urgent public health need for cancer patients to reduce their risk for COVID-19 exposure.

This study is 'A Randomized Phase 1 Double Blind Placebo Controlled, Single-Dose, Dose-Escalation Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Orally Inhaled Aerosolized Hydroxychloroquine Sulfate in Healthy Adult Volunteers.' The primary objectives are as follows: - To assess the safety and tolerability of AHCQ administered as a single dose by oral inhalation in healthy individuals at escalating doses until either the maximum tolerated dose (MTD) is identified or 1 mL of a 50 mg/mL solution is administered. - To determine the recommended Phase 2a dose (RP2D). Secondary objectives: • To characterize pharmacokinetics (PK) of single dose AHCQ in healthy individuals.

When the COVID-19 virus infects a person, it enters the lung epithelial cells of its host and uses its genetic material to replicate. The pulmonary epithelial cells of a part of the population, known as "secretors", are capable of expressing the antigens of the "ABO" system on their surface. This secretory status can be established by determining the antigens of the Lewis blood group system. When the virus replicates in an "secreting" individual, the antigens of the "ABO" system of the infected individual will be present on the surface of the viruses formed in his/her lungs. It was shown in 2003 that the response of a given individual to the transmission of a virus depends on his/her blood group and on the antigens of the "ABO" system carried by the virus. A patient of group "O" would thus defend himself much better against a virus carrying antigens of blood group "A", the natural antibodies "anti-A" of the patient reducing the ability of the virus to bind to its specific receptor on pulmonary epithelial cells, to penetrate them to replicate itself. The first data collected in Wuhan (China) seems to confirm this hypothesis. A COVID-19 virus transmission model can therefore be established on the basis of blood groups. In order to reduce the spread of the virus among nursing staff, it is possible to establish a preferential algorithm for patient management based on the "ABO" and "Lewis" blood groups of patients and "ABO" of nursing staff in health care units, if operational and human conditions allow.
