COVID-19 Clinical Trials and Expanded Access

Evaluating the rate of exposure to the virus in the close contact population who shared the home of a person infected with SARS-CoV-2 at the time of infection of the index case - adults or children - is a major factor in assessing the spread. virus in the family environment, assess the factors of circulation and determine whether immunity has been acquired. Screening for specific antibodies to SARS-CoV-2 will determine the exposure and protection acquired against this virus. Knowing the intra-family secondary transmission rate is essential for supporting the strategies for lifting the confinement envisaged and implementing a personalized approach. As of March 8, a platform for the home management of COVID + patients was set up when they, pauci or moderately symptomatic, do not require hospitalization. As of May 6, 2020, 881 patients have been registered in COVID and followed, constituting the active COVIDOM / PSL file. Of the 512 patients included between March 1 and 31, 45% have a household consisting of 3 people. All patients had weekly clinical follow-up by telephone for the duration of the disease with a maximum of 4 weeks having been achieved. If the recommendations of barrier gestures, isolation in an apartment were made during the symptomatic phase, the absence of masks available to all did not allow, in practice, to achieve the isolation and quarantine recommended ideally. to break the transmission of the virus. The FAMI-CoV study proposes to assess the rate of exposure to the virus in contacts sharing the same focus of index cases. A sub-study will assess the proportion of antibodies that have been neutralizing.

This is the first study of COVI-VAC in humans. The purpose of the study is to evaluate the safety and immune response of COVI-VAC (a live attenuated vaccine to prevent COVID-19) in healthy adults aged 18 to 30 years. Approximately 48 participants will be enrolled into 1 of 3 dose groups (low, medium, high). Within each of these dose groups, participants will be assigned randomly to receive either 2 doses of COVI-VAC 28 days apart, 2 doses of placebo (saline), or 1 dose of COVI-VAC and 1 dose of placebo. COVI-VAC or placebo is administered by drops into each nostril. Neither the participants nor the researchers will know whether COVI-VAC or placebo has been received. To assess the safety of the vaccine, each participant will record symptoms and oral temperature in a diary daily for 14 days after each dose. Safety laboratory tests, physical exams, ECGs, and a chest X-ray will also be performed, and peak expiratory flow and vital signs will be measured. Adverse events and medication use will be recorded. Blood samples and intranasal samples will be collected to assess the immune response from the vaccine.

This study is a randomized, double-blinded clinical Trial, to evaluate the non-inferiority of the commercial scale Inactivated SARS-CoV-2 vaccine against that of the pilot scale among adults aged 26-45 years, and the open-labelled, bridging non-inferiority of the vaccine induced immunogenicity in elderly against that in adults.

The hospital care of patients with cancerous pathology is part of a multidisciplinary care path that includes many stages. The treatment conditions in this course vary depending on the reasons that led to suspect the existence of a cancerous pathology: accidental discovery, screening, warning signs (sometimes expressed in an acute form) or referral for treatment in charge after the diagnosis has already been made. As soon as the patient presents to the hospital, various expertises are mobilized to establish the diagnosis, carry out the extension assessment and assess the comorbidities and conditions that may have an impact on the choice of treatments. During this initial evaluation, each file is evaluated in a Multidisciplinary Consultation Meeting to define the optimal therapeutic strategy which will often include several stages involving surgery, radiotherapy, medical oncology (chemotherapy, immunotherapy, targeted therapy, etc. hormone therapy), interventional radiology, and / or supportive oncological care (nutrition, pain treatment, correction of metabolic abnormalities, palliative care, etc.). This treatment path is considered to be very complex and the fluidity of its organization determines the processing times. The management of patients in a cancer department may vary depending on the organization specific to each hospital. The health crisis induced by the COVID-19 epidemic, associated with the containment measures put in place from March 19 to May 11, 2020, have limited the use of patients in hospitals, even for emergency activities. It has also led to a reorganization of scheduled activities within establishments, with a concentration of resources around unscheduled care, in particular COVID patients. In many establishments, the other activities were, for many, deprogrammed with postponed appointments. The impact of this epidemic on the hospital journey of patients with cancerous pathology is the subject of questions at the national level. The delays in diagnosis and treatment induced have possibly had an impact on the quality of the care and on the delays with, as a corollary, a possible loss of opportunity for the patient.

Study Rational Since December 2019, outbreak of COVID-19 caused by a novel virus SARS-Cov-2 has spread rapidly around the world and became a pandemic issue. First data report high mortality in severe patients with 30% death rate at 28 days. Exact proportions of the reasons of death are unclear: severe respiratory distress syndrome is mainly reported which can be related to massive cell destruction by the virus, bacterial surinfection, cardiomyopathy or pulmonary embolism. The exact proportion of all these causes is unknown and venous thromboembolism could be a major cause because of the massive inflammation reported during COVID-19. High levels of D-dimers and fibrin degradation products are associated with increased risk of mortality and some authors suggest a possible occurrence of venous thromboembolism (VTE) during COVID-19. Indeed, COVID-19 infected patients are likely at increased risk of VTE. In a multicenter retrospective cohort study from China, elevated D-dimers levels (>1g/L) were strongly associated with in-hospital death, even after multivariable adjustment. Also, interestingly,the prophylactic administration of anticoagulant treatment was associated with decreased mortality in a cohort of 449 patients, with a positive effect in patients with coagulopathy (sepsis-induced coagulopathy score ≥ 4) reducing the 28 days mortality rate (32.8% versus 52.4%, p=0.01). However the presence/prevalence of VTE disease is unknown in COVID-19 cancer patients with either mild or severe disease. Cancer patients are at a higher risk of VTE than general population (x6 times) and could be consequently at a further higher of VTE during COVID-19, in comparison with non-cancer patients. The exact rate of VTE and pulmonary embolism during COVID-19 was never evaluated, especially in cancer patients, and is of importance in order to understand if this disease needs appropriate prophylaxis against VTE. The largest series of cancer patients so far included 28 COVID-19 infected cancer patients: the rate of mortality was 28.6%. 78.6% of them needed oxygen therapy, 35.7% of them mechanical ventilation. Pulmonary embolism was suspected in some patients but not investigated due to the severity of the disease and renal insufficiency, reflecting the lack of data in this situation. The aim of the present study is to analyze the rate of symptomatic/occult VTE in a cohort of patients with cancer. Expected benefits Anticipated benefits of the research are the detection of VTE in order to treat it for the included patient. For all COVID-19 positive cancer patients it will enable to provide some guidelines and determine which patient are at risk for VTE and which will need ultrasound to detect occult VTE. Foreseeable risks Foreseeable risks for patients are non-significant because the additional procedures needed are ultrasound exam, and blood sample test. Methodology Retrospective and prospective (ambispective), multicentric study to evaluate the occurrence of venous thromboembolism during COVID-19 infection. Indeed, because the outbreak can end within the next 3-6 months, Investigators may not be able to answer the question if Investigators only focus on patients investigated prospectively. Investigators then decided to include patients from medical team who are already systemically screening patients with COVID-19 disease for VTE. Trial objectives Main objective To evaluate the rate of venous thromboembolism at 23 days during COVID-19 infection in cancer patients.

Vascular leakage following endothelial injury, responsible for interstitial and alveolar edema, is a major feature of pathogen induced acute lung injury. As acute respiratory distress syndrome (ARDS) due to pandemic Covid-19 is associated with more than 60% mortality, controlling vascular leakage may be a major target to decrease the mortality associated with the spreading of the disease in France. FX06, a drug under clinical development containing fibrin-derived peptide beta15-42, is able to stabilize cell-cell interactions, thereby reducing vascular leak and mortality in several animal models, particularly during lipopolysaccharide-induced and dengue hemorrhagic shock . A phase I study was conducted in humans, with no specific adverse event detected with a dose up to 17.5 mg/kg. In a phase II randomized multicentre double-blinded trial in 234 patients suffering from ST+ acute coronary syndrome, FX06 treated patients exhibited a 58% decrease in the early necrotic core zone. Importantly, adverse events were highly comparable between groups, indicating a high safety profile for the drug . Lastly, the drug was used as a salvage therapy in a patient exhibiting a severe ARDS following EBOLA virus infection . Altogether, those data indicate that FX06 is well tolerated in humans and is a potent regulator of vascular leakage. Our hypothesis here is that FX06 may decrease pulmonary vascular hyperpermeability during ARDS following SARS-CoV-2 infection, thereby improving gas exchanges and the outcome of infected patients.

Introduction: During pandemics like the COVID-19, a significant number of the populace suffer from psychological distress (PD) that often abates naturally over time in the majority of people but persists in others to become pervasive and severe enough to trigger the onset of common mental disorders (CMD) like major depressive disorders (MDD), generalized anxiety disorders (GAD), post-traumatic stress disorders (PTSD) and substance misuse disorders (SUD). Once identified, psychological distress as well as CMD can be managed using psychotherapy or pharmacotherapy. However, low levels of mental health literacy (MHL) manifested by the individual's unawareness of CMD symptoms, limited human and mental health infrastructure resources and high levels of mental illness stigma (MIS), are barriers to integration of mental health care in general health care during pandemics and epidemics such as the COVID-19. The study objectives will include: (a) Documenting MHL, PD, MDD, GAD, PTSD and SUD levels in the study population, (b) Determining the effectiveness of a psycho-education intervention delivered by village health team (VHT) members on study outcomes Methods: We shall employ an open label cluster-randomized trial design, with each village as a cluster, to conduct the study in 24 villages (12 intervention and 12 control villages) in Kampala (n= 15), Wakiso (n= 3), Masaka (n= 2) and Mukono (n= 4) districts. To ensure balance between the two study arms, villages underwent stratified randomization on the basis of rural vs urban population. The second level of stratification will be achieved by a separate randomization procedure performed within each stratum to ensure gender balance within each cluster We will develop information education and communication materials (IEC) aimed at improving MHL and reducing MIS. In the intervention arm (n=12 villages), VHTs will distribute the IEC materials in every 12th household till they accrue 420 individuals (adults ≥ 18 years old) who express interest in participating in the study. In the control arm (n=12 villages), VHTs will distribute MOH COVID-19 information leaflets in every 12th household till they accrue 420 individuals who express interest in participating in the study. Within 7days after distribution of the materials, trained research assistants will schedule and assess participants (through a phone interview) for MHL, PD, MDD, GAD, PTSD and SUD. Individuals who don't have phones will be asked to provide a phone number of a friend or relative through which the interviews can be conducted; interviews could also be conducted using the VHTs' phone. Cost data will be collected using available implementation data. We will document the number of individuals from both arms who will contact the investigators Data analysis plans: We will (a) report frequencies and percentages and their 95% confidence intervals for the first objective, (b) use an intention to treat analysis to analyze the second objective, Conclusion: Findings from this research will guide policy and practice regarding the integration of mental health services in the community in the context of epidemic preparedness and response.

The study proposes to test photodisinfection (PDF) on SARS-CoV-2 in the nose. The study will use Health Canada approved Steriwave™ Nasal Decolonization (ND) in he nostril of patients infected with SARS-CoV-2. Participants are swabbed for SARS-CoV-2 before and after the PDF treatment. For the study, a small group of healthcare workers who have tested positive for SARS-CoV-2 will be included. They will not undergo the treatment but will need to swab their noses multiple times over the next 5 days. This nil group will provide the effect (if any) of swabbing SARS-CoV-2 levels in the nose.

Examination of the prevalence of thrombosis in COVID-patients, especially in an out-patient setting. Assessment by duplex sonography. If thrombosis is detected, we will correlate it with immunity status. Assessment of health issues and cognitive function as late complication after infection.

In the context of the actual pandemia of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which requires a better diagnostic strategy for the management of patients. The study of volatile organic compounds (VOC) detected in exhaled air or in sweat, is an innovative research area for respiratory diseases. The analysis of VOC can be done either by the technique of the mass spectrometry which allows the identification of each VOC in the exhaled air or by the technique of electronic nose, simpler and faster, which provides an idea of the general profile of the VOC without identifying them. The VOC have shown their interest in some situations, such as diagnostic or prognostic tool in patients followed for thoracic tumorous pathology or bronchial or pulmonary vascular diseases. Moreover, it has recently been shown that properly trained dogs would be able to detect an olfactory signature of SARS-CoV-2 infection with a specificity greater than 90%; this olfactory signature corresponds to VOCs detectable by the flair of dogs (Nosaïs-Covid19 study). Validation of the diagnostic value of VOC analyzes by non-invasive and rapid methods (electronic nose analysis or mass spectrometry; detection by the scent of dogs) for the rapid detection and early diagnosis of a SARS-CoV-2 infection warrants the performance of this clinical study.
