COVID-19 Clinical Trials and Expanded Access

This study is a prospective, observational, open, monocentric multisite, pharmacokinetic study of hydroxychloroquine in critically ill patients. The aim of this study is to assess the pharmacokinetic behavior of hydroxychloroquine in COVID-19 critically ill patients treated with crushed hydroxychloroquine tablets (administered enterally using a nasogastric tube).

Our understanding of the clinical manifestations of COVID-19 is growing on a daily basis and there is evidence that increased age, cardiovascular risk factors and cardiac comorbidity are strongly associated with poor outcomes. Furthermore, myocardial injury occurs and is associated with a much worse outcome and rapid increase in mortality. There have been several reports of myocarditis and heart failure following infection. The mechanisms of myocardial injury and its consequences are not well understood. In an ongoing peer-reviewed and funded study, the investigators are evaluating the use of magnetic resonance imaging (MRI) to characterise and to understand the mechanisms of heart failure and myocarditis. Following strong encouragement by the British Heart Foundation, the investigators now propose to extend this investigation to patients who have recovered from COVID-19 infection to understand the mechanisms of myocardial injury that they have experienced. Using gadolinium and manganese-enhanced MRI combined with Computed tomography coronary angiography (CTCA), the investigators will assess the mechanisms and direct impact of myocardial injury in patients who have recovered from COVID-19 infection. This will help the investigators understand how best to manage individuals who demonstrate evidence of myocardial injury and potentially provide insights that could lead to novel treatment interventions to reduce such injury and improve patient outcomes.

This study will assess the safety and efficacy of a single dose of AZD7442(× 2 IM injections) compared to placebo for the prevention of COVID-19.

The investigators are conducting a pilot trial where they will study safety, efficacy and compliance in a cohort of ambulatory patients in the Ghent region with confirmed COVID-19 infection, in both an early stage of disease, defined as less than 5 days of symptoms and who at presentation do not meet any criteria for hospitalisation as well as asymptomatic individuals with a PCR CT value below 30. The primary endpoint is to assess the efficacy of the drug in terms of change from day 0 to day 5 in respiratory (oropharyngeal swab RT-PCR) log10 viral load. The aim of the study is to assess whether Camostat, a serine protease inhibitor available in an oral formulation has the potential to be studied as an antiviral drug in a large scale ambulatory setting to prevent transmission by decreasing viral load, to prevent symptoms after exposure (PEP) in asymptomatic individuals or to prevent disease progression in the occurrence of early symptomatology.

It is expected that large numbers of healthcare workers will experience a broad range of psychological reactions and symptoms including anxiety, depression, moral distress, and trauma symptoms that will cause both significant suffering as well as occupational and social impairment. The purpose of this study is to find interventions which are helpful in treating psychological distress in healthcare workers caring for COVID-19 patients. There are two phases of the study. All participants will take part in Phase I, which consists of 4 sessions over a two-week period of either a narrative writing intervention or a medical music intervention. Participants will be randomly assigned to the narrative writing intervention or medical music intervention. After Phase I, participants will be re-assessed. Healthcare workers who meet criteria for PTSD will be given the option to participate in Phase II of the study, in which they will be offered a choice between one of two evidence-based treatments for PTSD: Interpersonal Therapy (IPT) or Exposure Therapy (ET). Both treatments are comprised of ten 75-minute sessions scheduled twice weekly. Participants will be allowed to choose a preferred treatment in Phase II. After Phase II participants will complete a final assessment concluding the study. All interventions will be offered using distance technology.

Study objective is to evaluate the efficacy of the combination of masitinib and isoquercetin in adult hospitalized patients with moderate and severe COVID-19.

Although recognized as an autoimmune disease the etiology of type 1 diabetes remains unknown. Virus infections has been suggested as a possible agent triggering the autoimmune reaction finally resulting in beta-cell destruction and fate of insulin secretion. SARS Cov-2 virus enters the infected cells by binding to the ACE-2 receptor, which is abundant in many tissues including the pancreas. Accordingly, SARS Covid-19 infection may trigger the development of type 1 diabetes either by an activation of the immune system or directly via beta-cell infection and destruction. Our aim is to study the impact of the Covid-19 epidemic on the development of type 1 diabetes. This will be done in two ways: a clinical study and an epidemiological follow up. During the next two years, adult patients with newly diagnosed type 1 diabetes will be asked to participate. Type 1 diabetes will be diagnosed by usual means and a mixed meal tolerance test will be performed at time of diagnosis and after one year to evaluate beta-cell function. People with type 1 diabetes and serologically documented previous SARS Covid-19 will be compared with people with no previous infection regarding beta-cell function and fate of insulin secretion. In addition, we will estimate the number of new diagnosed type 1 diabetes patients compared to previous years.

The Coronavirus has caused containment of more than a third of the world's population. Containment can drastically change lifestyle habits, including eating habits such as the number of meals, meal times or their composition. However, there is currently no data on the influence of confinement on eating habits.

Bone and soft tissue sarcomas represent about 7-12% of all pediatric cancer and are a heterogeneous group of tumors arising in connective tissues embryologically derived from the mesenchyme. For some of these tumors relapse and mortality rates are still significantly high. Therefore, further studies are needed to better understand pathogenetic processes underlying sarcomas to offer new and more effective treatments. Next generation sequencing (NGS) has opened new frontiers for cancer research allowing to identify somatic or constitutional mutations known or yet unknown with the aim to better understand carcinogenesis. The establishment of the genomic profile of the tumor could also help clinicians to personalize patients treatment based on their genetic and molecular alterations.

COVID-19 has rapidly evolved into a generalized global pandemic. Post-exposure prophylaxis (PEP) against on COVID-19 was identified as an urgent research priority by the WHO, and lopinavir/ritonavir (LPV/r) is a promising candidate for both COVID-19 treatment and PEP, with a good safety profile and global availability. This is a cluster randomized controlled trial (RCT) of oral LPV/r as PEP against COVID-19, that will address the immediate need for preventive interventions, generate key data on COVID-19 transmission, and serve as a research platform for future vaccines and preventive agents.
