COVID-19 Clinical Trials and Expanded Access

Comparison of the effects of CYT107 vs Placebo administered IM at 10μg/kg twice a week for three weeks on immune reconstitution of lymphopenic COVID-19 patients

This is a bicentric, phase 2, randomized, open-label study to evaluate the efficacy and safety of maraviroc associated with standard treatment in hospitalized patients with pulmonary SARS-CoV-2 infection (COVID-19).

Aim of the study is to investigate whether the Covid-19 is found in the vaginal swab samples of female patients diagnosed with covid-19, to evaluate the presence of Covid-19 and the risk of transmission of Covid-19 by intercourse or vaginal delivery.

SARS-CoV-2 induced by COVID 19, involved the hospitalization of 101,932 patients in France, including 4,007 in intensive care (source: Santé Publique France). Alsace was one of the most affected regions on the metropolitan territory with a large number of patients hospitalized at the University Hospital of Strasbourg. In view of the seriousness of the epidemic and the rapid arrival of new patients requiring mechanical ventilation, 3 new intensive care units have been created on the NHC site alone, making it possible to accommodate a maximum of 111 patients (compared to 52 during normal periods).

Patients who are ill with COVID-19 may benefit from receiving convalescent plasma infusions containing antibodies from donors who have recovered from the disease and are proven to no longer be infected. Given the current public health emergency due to COVID-19, the FDA has recently fast-tracked the use of convalescent plasma. The purpose for this study is to assess if convalescent plasma collected from donors previously infected with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, can provide clinical benefit to those acutely ill with the virus and to evaluate if such treatment is safe. There will be two arms in the interventional study, where subjects will either be treated with convalescent plasma or fresh frozen plasma in a randomized and blinded manner. As an additional comparison, the clinical course of subjects enrolled during the period of the study who do not receive an alternative treatment for COVID-19 will be assessed.

A population-based COVID19 surveillance in a household cohort will be set-up using an existing Household demographic surveillance system (HDSS). From any individual in this population with any respiratory symptom or loss of smell or taste, with or without fever, investigators will collect a respiratory specimen and test these for SARS-CoV-2 virus, during 12 months. Demographic, epidemiological and clinical data of possible cases and of the source population will be recorded at baseline. An age-stratified serial sero-survey will be conducted at baseline in a subset of the population in the population-based COVID19 surveillance, and at 3, 6 and 12 months, after confirmation of community transmission.

The aim of this preliminary study is to describe the potential decline in forced expiratory volume in 1 second (FEV1) or forced vital capacity (FVC) as measured by home spirometry in high-risk subjects infected with COVID-19. We hypothesize that the magnitude of such a decline in FEV1 and/or FVC may be associated with clinical deterioration and hospitalization. The study will ultimately inform a larger subsequent RCT that will evaluate the efficacy of home spirometry in the early detection (pre respiratory symptoms) of respiratory complications and therefore prompt early medical attention which is a key for improving outcome.

This is a Phase 2, multicentre, randomized, double blind, 2 arm placebo-controlled study in adults with moderate COVID-19 with gastrointestinal signs and symptoms.

Hospital mortality attributed to SARS-CoV-2 in France increased daily by 28% in the week before confinement. The week following this decision, the daily increase was 30%. During the week of the second week of confinement, it started a decline of 19% estimated over the last 5 days, reaching the cumulative number of 2606 deaths on 29/3 (site https://www.eficiens.com/coronavirus- personal statistics / and calculation). The diagnosis of viral carriage by RT-PCR is reserved for symptomatic cases among caregivers, due to the shortage of available tests and the cumbersome implementation. The carrier diagnosis is the benchmark, on which are implemented the therapeutic strategies and established the national statistics. It can present false negatives, linked to a research too early or too late in relation to the infection, or to a technical defect of the nasal swab sample. Caregivers on the front line in patient care, in hospitals or in the city, have only partial access to this diagnostic test, depending on the existence of symptoms. The implementation of a systematic serological screening, planned by the government and which cannot be based only on the search for the virus, will make it possible to inform the caregivers presenting symptoms or not, of their serological status, and therefore of their degree immunity or, on the contrary, susceptibility to infectious contacts. It should therefore be very voluntarily requested. On the occasion of this screening, the constitution of the COVID-3S cohort will make it possible to verify the degree of contamination in an asymptomatic population, information which is sorely lacking for the estimation of the immune coverage of the population. The implementation of the Covid-3S study will be based on the work of the National Reference Center of Pr B Lina, from the COVID-SER cohort, for the selection of the most efficient test (s). It seems useful to initiate the constitution of this cohort as soon as possible in relation to the evolution of the epidemic. Pending receipt of official recommendations, the lack of knowledge of the performance of serological tests means that it should be applied first to health professionals, better able to appreciate its limits, for the initial period before determining a validated serological screening strategy. Once the strategy has been specified, the gradual expansion of screening to the patient population will provide a more representative basis for the construction of epidemiological models for evaluating strategies.

The purpose of this study is to evaluate the safety and effectiveness of NasoVAX in preventing worsening of symptoms and hospitalization in patients with early COVID-19.
