Active clinical trials for "COVID-19"

AICOVI (Adaptive Immune Response to COVID-19 Vaccination) is a prospective clinical cohort study aiming at studying the kinetics of vaccine-specific antibody production after COVID-19 vaccination in health care workers.

During the study, members of different online and offline communities will be followed post COVID-19 vaccination. Injection-site (local) and systemic reaction data will be assessed on vaccination day and afterwards using either web surveys or personal communication, depending on study participant preference. Hypothesis to be tested: The safety profile and the magnitude and durability of immune responses to the COVID-19 vaccines as well as adverse reactions depend on health conditions, metabolism and microbiomes.

Treatments for COVID-19 are urgently needed. Emricasan (EMR) is a pan caspase inhibitor. Caspase-1 plays a role in a form of cell death called pyroptosis. EMR inhibits pyroptosis. The Investigators have shown that peripheral blood lymphocytes of COVID-19 patients overexpress caspase-1, providing evidence for pyroptosis. A recent European study corroborate the Investigators finding as they have shown evidence for the activation of the inflammasome in COVID-19.

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.

To date, no treatment has demonstrated clinical efficacy on COVID 19. However, several therapeutic strategies are being considered and are being evaluated in numerous clinical trials. Among these strategies, the use of hydroxychloroquine (HCQ) seems promising. There is very little information on how to precisely administer hydroxychloroquine to patients infected with SARS-CoV-2 in intensive care, which may be responsible for side effects, some of which are potentially serious. In addition, this treatment has a long half-life which increases the risk of accumulation and therefore toxicity. In view of the lack of knowledge on the pharmacokinetic / pharmacodynamic properties of hydroxychloroquine in intensive care patients infected with SARS-CoV-2, we propose to perform a prospective multicenter cohort study in order to collect the biological data necessary for this evaluation.

The therapeutic hypothesis for the use of losmapimod in COVID-19 disease is that increased mortality and severe disease is caused by p38 mitogen-activated protein kinase (MAPK)-mediated exaggerated acute inflammatory response resulting from SARS-CoV-2 infection. The study Sponsor hypothesize's that the early initiation of p38α/β inhibitor therapy in patients hospitalized with moderate COVID-19 who are at increased risk of a poor prognosis based on older age and elevated systemic inflammation will reduce clinical deterioration including progression to respiratory failure and death. To address this hypothesis, Fulcrum Therapeutics is conducting a Phase 3, multicenter, randomized, double-blind, placebo-controlled study that will evaluate the safety and efficacy of losmapimod versus placebo in subjects 50 and older who are hospitalized with moderate COVID-19 disease.

Stress is underpinned by a biological reaction of the organism allowing the production of energy to respond to a change in the environment (or stressor). Stress reaction is expressed in behavioural, cognitive, emotional and physiological terms. This biological response is non-specific because it is the same regardless of the stressor. Its evolution over time has been conceptualised by Hans Selye (1956) in the General Adaptation Syndrome (GAS) which comprises three successive phases. (i) The first phase, known as the alarm phase, corresponds to the activation of all biological mechanisms according to a trend regulation, allowing a rapid response to the stressor. (ii) The second phase of resistance which adjusts the stress response to the intensity of the perceived aggression according to a constant regulation. (iii) When the aggression disappears, a recovery phase dominated by the return of the parasympathetic brake allows a return to homeostasis (eustress). The "primum movens" of all pathologies is therefore the inability of the individual to adapt his stress response in duration and/or intensity to the course of the phases of the GAS (distress). The perception of not being in control of the situation contributes to the perceived stress and constitutes a well-established risk of distress. It is a risk factor for the emergence of burnout. It induces a biological cost called allostatic cost. Allostasis is a concept that characterizes the process of restoring homeostasis in the presence of a physiological challenge. The term "allostasis" means "achieving stability through change", and refers in part to the process of increasing sympathetic activity and corticotropic axis to promote adaptation and restore homeostasis. Allostasis works well when allostasis systems are initiated when needed and turned off when they are no longer required. Restoring homeostasis involves effective functioning of the parasympathetic system. However, when the allostasis systems remain active, such as during chronic stress, they can cause tissue burnout and accelerate pathophysiological processes. The perception of uncontrollability depends on the stress situation, the psychological and physiological characteristics of the subject and his or her technical skills in responding to the stressors of the situation. In particular, subjects with a high level of mindfulness are more accepting of uncontrollability and less likely to activate the stress response. The COVID-19 pandemic situation is a situation characterized by many uncertainties about the individual, family and work environment and the risk of COVID infection. Healthcare workers, like the military, are high-risk occupations that are particularly exposed to these uncertainties in the course of their work and continue to work in an uncertain situation. These professionals are described as a population at risk of occupational/operational burnout that the level of burnout operationalises. This ancillary study in a population of civilian and military non-healthcare workers will complement the study conducted among military health care workers. It will make it possible to isolate the specificity of each profession (civilian or military, healthcare personnel or not) with regard to the risk of burnout in the COVID context. The objective of this project is to evaluate the impact of the perception of non-control in the operational burnout of experts in their field of practice and to study the psychological and physiological mechanisms mediating the relationship between the subject's characteristics, perceived non-control and burnout.

Study D822FC00005 will investigate the Phamacokinetics, Safety and tolerability of Acalabrutinib suspension when delivered via a nasogastric tube and co-administered with a Proton Pump Inhibitor, in the treatment of COVID-19.

The aim of this study is to test Cenicriviroc (CVC) as a means to reduce the severity of the lung disease COVID-19 caused by an infection with SARS-CoV-2. The safety of CVC, when administered to COVID-19 patients, will also be assessed. Furthermore, the clinical trial aims to answer the question of whether patients with pre-existing conditions, who have an increased risk of severe COVID-19 progression, benefit more and particularly from CVC. CVC is an orally available dual inhibitor of the chemokine receptors CCR2 and CCR5, which is expected to reduce (hyper-) inflammation in COVID-19. The main goal of the study is to determine whether CVC helps increase the number of patients who are symptom-free and not hospitalized after 14 days compared to a placebo. Approximately 66.7% of the patients enrolled in the study will receive CVC and 33.3% will get an optically identical pill (placebo). Subjects will be assessed daily while hospitalized. Discharged patients will be asked to attend study visits at Days 8, 15, 22, and 29 and 85. All subjects will undergo a series of clinical, safety, and laboratory assessments. Blood samples and oropharyngeal (OP) swabs will be obtained on Day 1; 3, 5 (while hospitalized); and Day 8, 15 and 29 (if able to return to clinic or still hospitalized). The presence of anti-SARS-CoV-2 antibodies will be determined on Days 29 and 85.

Disulfiram (DSF) a safe, easily dosed, FDA-approved drug for the treatment of alcohol dependence has been identified to be a potential therapeutic target for SARS-CoV-2 infection. Disulfiram may have both antiviral (inhibiting viral replication via blocking the Mpro protease and zinc ejection) and anti-inflammatory effects (via inhibition of NF-kB-induced and NLRP inflammasome-induced cytokine release) on SARS-CoV-2. We will study oral disulfiram given for 5 consecutive days (1000 mg/day in cohort 1; 2000 mg/day in cohort 2) in 60 symptomatic COVID+ individuals in a randomized (2:1) randomized, double blind placebo-controlled trial evaluating disulfiram's effect on COVID-19 symptom severity, SARS-CoV-2 viral load, and biomarkers of inflammation and pyroptosis (aberrant pro-inflammatory cell death) over 31 days.
