COVID-19 Clinical Trials and Expanded Access

Primary Objective: To assess the effect of hydroxychloroquine versus placebo on nasopharyngeal SARS-CoV-2 viral load in outpatient adults with COVID-19 Secondary Objectives: - To assess the effect of hydroxychloroquine versus placebo on clinical signs and symptoms and progression of disease in outpatient adults with COVID-19 - To assess the safety and tolerability of hydroxychloroquine in outpatient adults with COVID-19

Currently there are no proven treatment option for COVID-19. Human convalescent plasma is an option for COVID-19 treatment and could be available from people who have recovered and can donate plasma.

Desynchronization of infection rates in healthcare workers will potentially reduce the early infection rates and therefore maintain workforce for late time points of the epidemic. Given the current threat of the COVID-19 epidemic, the department for Visceral Surgery and Medicine, Bern University Hospital, has decided to limit its elective interventions to oncological and life-saving procedures only. At the same time, the medical team were split in two teams, each working for 7 days, followed by 7 days off, called a desynchronization strategy. Contacts between the two teams are avoided. The main aim of present study is to determine, if the infection rate between the two populations (at work versus at home) is different. Secondary aims are to determine if the workforce can be maintained for longer periods compared standard of care, and if the infection rate among patients hospitalized for other reasons varies compared to the community.

A prospective, controlled, randomized, multicenter study whose goal is to compare the efficacy of an autophagy inhibitor (GNS561), an anti-NKG2A (monalizumab) and an anti-C5aR (avdoralimab) versus standard of care in patients with advanced or metastatic cancer who have Sars-CoV-2 infection not eligible to a resuscitation unit. According to their severity level at the time of enrolment, eligible patients will be randomized into 2 different cohorts: - COHORT 1 (mild symptoms or asymptomatic): GNS561 vs anti-NKG2A vs standard of care (randomization ratio 1:1:1). - COHORT 2 (moderate/severe symptoms): anti-C5aR vs standard of care (randomization ratio 1:1).

Background and Project Rationale: Degenerative aortic valve stenosis affects 2% of the elderly population aged 70 years or older and progresses insidiously with advancing age [1] before manifesting with symptoms such as decreased exercise tolerance, shortness of breath, chest pain and syncope on exertion. Without aortic valve replacement, the survival prognosis of patients with symptomatic aortic stenosis is poor. In the PARTNER 1B trial, all-cause mortality among 179 inoperable patients with severe symptomatic aortic stenosis allocated to conservative management amounted to 51% at one year [2]. Consistently, prospective registry data reported a mortality rate of 55% at 1 year in 78 patients with severe aortic stenosis undergoing conservative management [3]. The rapid spread of the SARS-CoV-2 pandemic represents an unprecedented challenge for healthcare systems. A limited number of ventilators and ICU beds call for a careful allocation of healthcare resources. On March 20 2020, the Federal Council prohibited elective interventions in all hospitals in Switzerland. Patients with untreated severe aortic stenosis are particularly vulnerable to SARS-CoV-2 infection [4] and face the dual risk of cardiac death from aortic stenosis on one side, and death from acute respiratory distress syndrome secondary to SARS-CoV-2 infection on the other. While the balance between the two risks is a matter of clinical judgement, the investigators established an algorithm for the management of patients with severe aortic stenosis during the SARS-CoV-2 pandemic. Patients with aortic stenosis deemed critical will undergo valvular replacement in spite of the ongoing pandemic while patients with severe but not critical aortic stenosis will undergo deferred intervention once the number of new SARS-CoV-2 infections flattens. In the current situation, aortic valve replacement in patients with severe, non-critical aortic stenosis will be deferred in order to give priority to SARS-CoV-2 patients. This unique situation allows the investigators to study the effect of deferral of aortic valve replacement in patients with severe aortic stenosis. The study is an amendment to the Swiss-TAVI registry. In contrast to the Swiss-TAVI registry, patients are not enrolled at the time of aortic valve replacement, but already at the time of referral for aortic valve replacement. Primary Objective: The aim of the present observational study is to explore the effect of deferral of valvular replacement in patients with severe but not critical aortic stenosis on morbidity and mortality. The primary objective is to describe rates of morbidity and mortality among patients with severe but not critical aortic stenosis in the interval from referral/indication for valvular replacement to intervention. Project Design: The study is a prospective cohort study of patients with severe aortic stenosis referred for aortic valve replacement. All referrals for aortic valve replacement will be allocated to either "transcatheter aortic valve replacement (TAVR)/ surgical aortic valve replacement (SAVR) (standard of care)" or "deferred intervention" based on prespecified criteria. Patients with critical aortic stenosis as defined by an aortic valve area (AVA) 60 mmHg or a history of cardiac decompensation during the previous 3 months or clinical symptoms on minimal exertion (NYHA III) will be allocated to TAVR or SAVR. All other patients with severe aortic stenosis defined by an AVA

The overall objective of the study is to determine the therapeutic effect and tolerance of Tocizilumab in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Tocilizumab (TCZ) is an anti-human IL-6 receptor monoclonal antibody that inhibits signal transduction by binding sIL-6R and mIL-6R. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Tocilizumab administration to patients enrolled in the COVIMUNO-19 cohort. Tocilizumab will be administered to consenting adult patients hospitalized with CORVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. Patients who will chose not to receive Tocilizumab will receive standard of cares. Outcomes of Tocilizumab-treated patients will be compared with outcomes of standard of care treated patients as well as outcomes of patients treated with other immune modulators.

This individually randomized telemedicine-based trial aims to evaluate the efficacy of a single dose of azithromycin for prevention of progression of COVID-19 in patients with a recent positive SARS-CoV-2 test who are not currently hospitalized.

The aim of the study is to evaluate whether the therapy with chloroquine phosphate (CQ, in combination with telemedical approach) in addition to standard care is effective and safe in reducing composite endpoint of COVID-19-related hospitalization or all cause death, in ambulatory patients with SARS-SoV-2 infection at particular risk of serious complications due to advanced age and/or comorbid conditions (in comparison with subjects not treated with CQ but receiving standard care and supervised telemedically).

COVID-19 is a respiratory disease caused by the new coronavirus (SARS-CoV-2) and causes considerable morbidity and mortality. Currently, there is no vaccine or therapeutic agent to prevent and treat a SARS-CoV-2 infection. This clinical trial is designed to evaluate the use of Tocilizumab in combination with hydroxychloroquine and azithromycin for the treatment of hospitalized adult patients with COVID-19.

The viral Covid-19 outbreak is now considered a pandemic according to the World Health Organisation (WHO). A free monitoring app 'COVID-19 Symptom Tracker' has been developed to record and monitor the symptoms of the COVID-19 coronavirus infection; tracking in real time how the disease progresses. The app also records how measures aimed at controlling the pandemic including self-isolation and distancing are affecting the mental health and well-being of participants. The data from the study will reveal important information about the symptoms and progress of COVID-19 infection in different people, and why some go on to develop more severe or fatal disease while others have only mild symptoms do not.
