COVID-19 Clinical Trials and Expanded Access

This is a longitudinal study in which participants that have been confirmed by a National Health Service (NHS) swab test as COVID-19 positive will be asked to provide faecal and saliva samples, and complete short health/lifestyle questionnaires at the time of sampling (referred to as a sample set). The number of sample sets collected from any participant will be dependent on how long the SARS-CoV-2 virus persists within the stool. The investigators aim to collect a minimum of 4 and a maximum of 8 sample sets, and will target all COVID-19-positive subjects, with the exception of those severally ill (e.g. in the intensive care unit (ICU)). The investigators aim to recruit a minimum of 100 and up to 200 participants. To obtain the desired numbers, it may be necessary to continue recruitment during any further United Kingdom (UK) COVID-19 infection peaks.

The purpose of the study is to determine if Liquid Alpha1-Proteinase Inhibitor (Human) (Liquid Alpha1-PI) plus SMT can reduce the proportion of participants dying or requiring intensive care unit (ICU) admission on or before Day 29 or who are dependent on high flow oxygen devices or invasive mechanical ventilation on Day 29 versus placebo plus SMT in hospitalized participants with COVID-19.

Part I: 12 subjects will receive an open-label 500 µl subcutaneous injection via needle and syringe of the study IMP (CoVac-1). No more than one subject per day will be enrolled. 28 days following vaccination of the 12th volunteer, there will be an interim analysis of safety and a safety review by the data safety monitoring board (DSMB) as well as an amendment to the regulatory authorities (Paul-Ehrlich Institute and Ethics Committee) before proceeding to Part II. Part II: 12 subjects will receive an open-label 500 µl subcutaneous injection via needle and syringe of the study investigational medicinal product (IMP) (CoVac-1). 28 days following vaccination of the 12th volunteer, there will be an interim analysis of safety and a safety review by the DSMB whether to proceed to next Part III. Part III: 12 subjects will receive an open-label 500 µl subcutaneous injection via needle and syringe of the study IMP (CoVac-1). The aim of the clinical is to evaluate the safety and immunogenicity of a single use of a SARS-CoV-2-derived multi-peptide vaccine in combination with the toll like receptor (TLR)1/2 ligand XS15 in adults

The Paris Fire Brigade staff have been particularly exposed to COVID-19 due to rescue and care activities for victims at risk in Paris area (where the virus was actively circulating). In addition, when the pandemic began in France, they had to take care of patients before procedures to protect caregivers were implemented. The contamination of young military personnel, whose physical capacity was put into strain at work, raises the question of the consequences of COVID-19 on their physical fitness. At the time, the medium- and long-term evolution of this disease and its possible repercussions on physical fitness are unknown. Moreover, like any soldiers who have been confined, they may present at least a cardio-respiratory deconditioning (sometimes independent of the disease making it difficult to distinguish between a sequelae of the infection or rehabilitation). Based on previous coronavirus epidemics (Sars-Cov 1 and Mers-Cov), it appears that long-term sequelae are possible even in mild forms and can result in an alteration of exertion ability. In the current context and in the absence of national or international recommendations on the return to physical activity, the French Armed Forces Health Service has proposed a simple management plan aiming at: i) allowing mass screening for possible exercise intolerance and targeting at-risk personnel, ii) allowing individualized re-training and iii) guaranteeing that military personnel can carry out their mission without jeopardizing their health.

Safety and Effectiveness Evaluation of Seraph 100 Microbind Affinity Blood Filter (Seraph 100) in the treatment of patients with COVID-19

The current project is based on the immunological studies covering the potential of disease induced immunoglobulins as treatment regime. We would be able to generate the concentrated antibodies specific against coronavirus (Covid-19). These antibodies can be used as serum therapy. Aside from a Covid-19 vaccine, antibodies from recovered patients could provide a short-term "passive immunization" to the disease. Those antibodies can be extracted from the blood serum of surviving patients and then injected into infected people. Passive immunization usually lasts for a few weeks or months, after which those borrowed or donated antibodies, get broken down by the host body within about 30 days. While drugs to treat patients with covid-19, and vaccines to prevent infection are being developed, a fast acting, stopgap serum therapy could be useful as a first aid for high-risk patients.

Plasma, the supernatant part of blood, contains a variety of different proteins, including immunoglobulins. These proteins, also called antibodies, are directed to previous foreign infecting organisms, such as virus, bacteria or parasites. Patients recovering from SARS-Cov-2 infection may develop protective antibodies which can prevent reinfection with the same agent or similar organisms with shared molecular structures. Those antibodies may be transferred to other patients through collection of such convalescent plasma from recovered donors and its transfusion to ill patients. In this research, the primary hypothesis is that those antibodies can exert passive immunization and help ameliorate symptoms from COVID-19 (Coronavirus Disease 2019), resulting in higher clinical improvement rates at day 28, especially when administered early in the infection course.

This study aims to determine if a strategy of recommending prone (on stomach) positioning of patients positive or suspected positive for coronavirus disease 2019 (COVID-19) requiring supplemental oxygen, but not mechanically ventilated, Is feasible in the inpatient setting. This study will be performed as a pragmatic pilot clinical trial to gain information relevant to the future conduct of a larger trial.

Viral pandemics, such as HIV and SARS-Cov-V1, have shown that they can lead to acute and / or delayed neurological complications. At the actual context of the pandemic Coronavirus disease 2019 (COVID-19), neurological manifestations seem to be confirmed since in 85% of COVID-19 patients, present neurological symptoms, including anosmia, ageusia, periorbital pain, dizziness, fatigue, even moderate headache, moderate memory and/or behavioral disorders. However, these neurological manifestations are not well studied and their radiological features are not well described. It is therefore important to assess these potential neurological complications in COVID-19 patients. To the investigator knowledge, there is no previous study in the literature describing spectral brain changes in COVID + patients. Thus, the goal of this work is to describe the radiological semiology using MRI and particularly Magnetic Resonance Spectroscopic (MRS) biomarkers in the evaluation of acute and / or delayed brain damage in COVID + patients presenting a neurological manifestations that are initially related to the cranial nerves damage.

The goal of the study is to examine whether a shared decision making intervention improves decision making about colon cancer screening for patients who had their colonoscopy delayed or postponed due to the COVID pandemic. Eligible patients (n=800) will be randomly assigned to either the intervention or control arm. A subset will be surveyed about 6-8 weeks post intervention to measure shared decision making, their intention to follow through with screening, and their decisional conflict. Study staff will conduct medical chart review to track receipt of colon cancer screening within 6 months. The statistician will test whether patients in the intervention arm report more shared decision making, less decisional conflict, higher intention to follow through on screening and have higher screening rates compared to those in the control arm.
