Active clinical trials for "COVID-19"

During the COVID-19 (corona virus) pandemic the research arena has had to rapidly adapt and change in order to facilitate and deliver research. The UK (United Kingdom) government and Public Health England have stressed the importance of such research to find solutions to treating, preventing and stopping the spread of COVID-19. Due to national and international 'lock down restrictions' delivering research in care home settings has become even more challenging. The adaptations to conducting consultations have relied heavily on the use of technology, for example video calling, telephone, email, and teleconferencing. It is suggested that the use of technology in care home settings is already a barrier to effective research delivery. Nevertheless, as care home residents are a vulnerable group, it is critical to include these groups in research in order to enable improved and evidence-based care and their access to new and emerging treatments. This study aims to assess the opinions and experiences of key stakeholders to identify barriers, and enable better facilitation of research in these settings during and post pandemic.

It has been well documented that patients in the intensive care unit (ICU) are susceptible to developing neurocognitive and musculoskeletal complications because of various factors, including the nature of the critical illness, medications, over-sedation, and pain. Neuro-stimulants are used to speed up physical and mental processes through the increase in neurotransmitter, which translates into increase in arousal, wakefulness, attention, memory, mental and motor processing speed. The investigators reviewed the literature and described the clinical characteristics for a case series of adult patients admitted to COVID and non-COVID ICU between January 2017 and June 2020, who received modafinil to promote wakefulness and improve cognition at the King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Riyadh, Saudi Arabia. The secondary goals to describe the change of Glasgow Coma Scale (GCS) before and after the start of modafinil therapy, ICU and hospital length of stay, discharge disposition, adverse drug effects, and mortality rate.

The overarching objective for this prospective cohort study of COVID-19 in adolescents is to study the long-term effects, with particular emphasis on post-infectious chronic fatigue. A total of 500 individuals with a SARS-CoV-2 positive test will be enrolled in the acute phase of COVID-19 and followed for 6 months. A total of 100 individuals with SARS-CoV-2 negative test will be included during the same time period as a control group. Investigations include autonomic, pulmonary and cognitive assessement; a questionnaire charting symptoms, emotionality, personality, loneliness, life events and demographics; and extensive biobanking including genetic markers, viable PBMC, urine, feces and hair. A subgroup of 40 SARS-CoV-2 positive and 20 SARS-CoV-2 negative individuals will also undergo detailed cardiological examination by echocardiography. Primary endpoints are fatigue at 6 months as assessed by the Chalder Fatigue Scale and post-COVID-19 syndrome cases at 6 months according to the WHO definition

The study has a retrospective and a prospective component. The retrospective component aims to review data of all airway management related SAEs in COVID 19 patients (between April and July 2020); hypoxemia, hypotension and cardiac arrest within 15 min of intubation. The prospective component aims to assess the incidence of COVID-19 infection in Airway Management Team members by means of an interview assessing their COVID19 status after participating in airway management in the period outlined above. This prospective interview component is starting in December 2020.

Vitamin D is a secosteroid hormone which may have beneficial role in reducing COVID-19 adverse outcomes by first regulating the renin angiotensin system (RAS). Recent studies on animal in which acute respiratory distress syndrome (ARDS) was induced, showed that vitamin D lead to pulmonary permeability reduction by modulating RAS activity as well as the expression of the angiotensin-2 converting enzyme (ACE2). During COVID-19, downregulation of ACE2 leads to cytokine storm in the host, causing ARDS. In contrast, an experimental study conducted on mice in which ARDS was induced chemically, revealed that vitamin D admiration contributed to mRNA and ACE2 proteins levels improvement, ADRS milder symptoms as well as less lung damage. Additionally, vitamin D had shown antiviral effects on several previous studies, that though to be exerted either by antimicrobial peptides induction which subsequently had direct antiviral action or through immunomodulatory and anti-inflammatory effects. In addition, vitamin D stabilizes physical barriers which prevent viruses from reaching tissues susceptible to infection. Finally, previous studies demonstrated that hypovitaminosis D is accompanied by various comorbidities including diabetes mellitus, hypertension, chronic cardiovascular and respiratory diseases, and cancers, all medical conditions that are considered risk factors of COVID-19 infection deterioration and even high mortality rate. The objective of this study is to evaluate whether supplementation with high-dose vitamin D improves the prognosis of patients diagnosed with COVID-19 compared to a standard dose of vitamin D.

The study Global sponsor is planning several parallel studies of Sputnik-Light vector vaccine across the globe in United Arab Emirates, Russia and possibly in other countries in case of confirmation associated with the same medical product under similar protocols. The key objective of this study is to be conducted in several parallel studies of the same vaccine above the other countries. Using similar protocols on a portfolio basis of studies let us collect data for Efficacy, Immunogenicity, Safety and Tolerability confirmation of the Sputnik-Light vaccine.

Investigators study meet the World Health Organization definition of a clinical trial because it is a prospective study in which participants will be assigned to intervention groups to investigate the effects on health outcomes. Investigators highlighted clearly the real problem that indigeneous patients are facing now in the Democratic Republic of the Congo: Poverty meaning the lack of money to buy goods and drugs. From the news report, investigators learned that "In the Democratic Republic of the Congo, indigenous communities in Kananga, Tshikapa and in the Kasai region are increasing their consumption of "Vernonia amygdalina," a traditional plant believed to cure several diseases, including alleviating COVID-19." Based on an unpublished work, quite a few extract molecules of Vernonia amygdalina are excellent antiviral candidates which are the family members of Remdesivir in terms of their antiviral mechanisms. Furthermore, the antiviral capabilities of these molecules are significantly stronger than or at least equivalent to Remdesivir. The target zones of these molecules in the human body cover a set of important organs and tissues. For example, Vernolide (C19H22O7) is able to reside firmly at bronchi, the upper respiratory tract, and blood vessels. From the news report, investigators learned also that Herbs used in Tanzania include lemon, ginger, neem tree leaves, mango tree leaves, orange tree leaves. These traditional medicines contain, more or less, antiviral molecules whose capacities range from good to outstanding levels. Those herbs have been used worldwide to fight COVID-19. In conclusion traditional medicines have been playing important roles not only in Africa but also in Asia, in South America, etc. Herbs prove themselves with effective efficacies in many therapeutic practices. So maybe after careful considerations, the World Health Organization may support the use of herbs for poor patients who cannot afford modern drugs and used traditional medicines after a positive COVID-19 test in the Democratic Republic of the Congo. Investigators are talking about a randomisation's nuance process to follow participants who decide by themselves if diagnosed positive to COVID-19 to begin to take herbs not waiting for a physician prescription.

In this randomized double blind Phase 3 clinical trial we will study the efficacy and safety of oral polio vaccine with and without NA-831 versus placebo.

While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.

COVID-19, spreading rapidly all over the world, causes serious morbidity and mortality. In severe COVID-19 infections, after pulmonary inflammation, cardiovascular organ failure, cytokine storm, hemophagocytosis, septic shock, develops due to uncontrolled hypoxia, and isolated organ failure turns into multi-organ failure. It is noteworthy that it causes lymphopenia in patients. In the studies, the blood levels of certain inflammatory cytokines, interleukin-1β,interleukin-6 and TNF-α, were evaluated. In addition, blood values of a limited number of cytokines were investigated similarly in a limited number of studies published in our country.
