COVID-19 Clinical Trials and Expanded Access

The prevalence and typical patterns of neurological complications in hospitalized COVID-19 patients admitted to the intensive care units of the University Hospital Zurich will be investigated. The impact of neurological complications among COVID-19 patients on mortality, functional outcome, and organizational outcomes will be analyzed.

Background: Sickle cell disease (SCD) is a chronic illness. It affects about 100,000 people in the United States. People with SCD have red blood cells that are sickle-shaped and impaired in their function. This results in a lifetime of complications that affect every organ system. People with SCD also are at greater risk for respiratory infections and lung problems. Researchers want to study how this population s stress, anxiety, fear, pain, sleep, and health care use are being affected by the COVID-19 pandemic. Objective: To study the extent and impact of life changes induced by the COVID-19 pandemic on people living with SCD in the U.S. Eligibility: People age 18 and older with SCD who live in the U.S. Design: Participants will complete a survey online. The questions will focus on the following: Medical history Mental and physical health Demographics Stress Resilience Health care use COVID-19 Beliefs about medical mistrust and participation in research. At the end of the survey, participants will be asked if they would like to take the survey again in the future. If they reply "yes," then they will be contacted by the study team in 6-9 months to take the survey again. They may complete the survey again in 6-8 months, 12-15 months, and 18-21 months. The survey should take less than 40 minutes to complete. Participants' data will be coded to protect their privacy. The coded data may be shared with other researchers.

Randomized, double-blind, of standard of care vs additional communication and factorial design of intervention letter vs. control letter and EHR vs mail delivery mechanism in patients who canceled visits and did not reschedule over a 90 day period starting March 9, 2020.

According to epidemiological models, the seroprevalence of SARS-CoV-2 infection in Île-de-France as of 11 May was between 10 and 15%. Preliminary data on the number of professionals evicted from nurseries on suspicion of COVID-19 (on clinical grounds) seem to be of the same order of magnitude, but need to be confirmed by a biological technique. Children would be susceptible to infection but often asymptomatic.

Based on findings of the interim analysis of the ACTIVATE study showing 53% decrease of the incidence of all new infections with BCG vaccination, a new trial is designed aiming to validate if BCG can protect against COVID-19 (Corona Virus Disease-19).The aim of the study is to demonstrate in a double-blind, placebo-controlled approach if vaccination of participants susceptible to COVID-19 with BCG vaccine may modulate their disease susceptibility for COVID-19. This will be validated using both clinical and immunological criteria. At the same time, a sub-study will be conducted and the mechanism of benefit from BCG vaccination by assessing its effect on vascular endothelial function and mononuclear blood cells will be studied

This study intends to find out how a cloth mask may impact exercise capacity, to provide guidance for exercisers to adjust their expectations and training accordingly. The investigators plan to asses exercise capacity through estimated peak oxygen consumption (eVO2peak), oxygen saturation and level of perceived exertion during treadmill based exercise while wearing a cloth mask compared to exercising without a cloth mask. The potential significance of this study is to determine if subjects can exercise safely and if their exercise training needs to be adjusted while following the current recommendations of wearing a cloth mask in public. The degree of airflow limitation experienced will depend on the type and fit of the mask being worn, and inadequeate airflow could possibly result in CO2 re-breathing if all air was not fully discharged from the mask with each breath. This re-breathing of CO2 could potentially limit the workload leading to a detriment in performance, and increase in adverse symptoms such as dizziness, lightheadedness, chest pain or shortness of breath that does not improve with rest.

The actual worldwide context (disease outbreak, confinements instaured in many countries) is a stressful factor for many people. It can have consequences on mental health : separation from loved ones, loss of freedom, uncertainty about infection status, boredom. Patients with mental disorders are especially vulnerable. On march 17th, the french government ordonned a national confinement to slow the progression of the COVID-19 outbreak, for 15 days at first then renewed several times. This situation has led to a reorganization of care as requested on March 22nd, 2020 in the recommendations applicable to the organization of care in psychiatric services : priority to telephone contacts and teleconsultation by multiplying contacts and assessments. By the time the reorganization of care became operational, the most vulnerable patients may have experienced a decompensation of their disease. It is important to know if the COVID-19 outbreak combined with the confinement increased the number of unvoluntary commitment the month after the announce of the confinement. This could help us understand which patients are more vulnerable is this context, and improve our organization (ambulatory and hospitalization care) if this situation occurs again.

This proof of concept study will take place in the US and other countries in approximately 15 clinical sites and will enroll about 40 hospitalized patients diagnosed with COVID-19 infection who have developed pneumonia and require supplemental oxygen. 20 patients will receive opaganib in addition to standard of care twice each day for 14 days. 20 will receive matching placebo in addition to standard of care unless the patient has been discharged from the hospital without requiring supplemental oxygen, in which case study drug will only be administered for 10 days. All participants will be followed up for 4 weeks after their last dose of study drug.

The purpose of this study is to determine whether hydroxychloroquine is an effective prophylactic regimen to prevent SARS-CoV-2 infection among healthcare workers. Participants will be randomized into two parallel groups. The first arm will evaluate the use of hydroxychloroquine every-other-day plus standard measures of protection for the prevention of SARS-CoV-2. The second arm will evaluate the use of standard measures of protection for the prevention of SARS-CoV-2. The target enrollment is 320 participants. Each study participant will be monitored for SARS-CoV-2 seroconversion in weekly visits or for the development of COVID-19 symptoms for 8 weeks.

Since the start of this epidemic, numerous clinical and fundamental studies have been conducted to best adapt the individual management of COVID-19 cases [1-6]. In parallel with this work, it is necessary to better understand the characteristics of the epidemic in the general population but also in the population working in healthcare settings more exposed to SARS-CoV-2. Seroprevalence studies are therefore particularly useful in order to understand the collective immunization rate and the factors that can explain this immunization.
