Active clinical trials for "COVID-19"

The purpose of this initial study is to evaluate a new form of cognitive rehabilitation therapy for improving your ability to think, particularly how rapidly you process information that you receive from your senses, e.g., sight, hearing, and smell. The study will also test how often and how well you carry out tasks that rely on thinking in your daily life. You will be randomly assigned to receive the new therapy soon or about three months later. In other words, your treatment schedule will be determined by chance. The new therapy involves intensive, repetitive cognitive exercises (up to 3.5hr/day for 10 consecutive weekdays) with rest periods interspersed as needed.

Small molecule inhibitors have previously been investigated in different studies as possible therapeutics in the treatment of SARS-CoV-2. In the current drug repurposing study, the investigators identified the leukotriene (D4) receptor antagonist Montelukast as a novel agent that simultaneously targets two important drug targets of SARS-CoV-2. The investigators initially demonstrated the dual inhibition (main protease and Spike/ACE2) profile of Montelukast through multiscale molecular modeling studies. Next, the investigators characterized its effect on both targets by different in vitro experiments including the Fluorescent Resonance Energy Transfer (FRET)-based main protease enzyme inhibition assay, surface plasmon resonance (SPR) spectroscopy, pseudovirus neutralization on HEK293T / hACE2, and virus neutralization assay using xCELLigence MP real time cell analyzer.

In December 2019, viral pneumonia (Covid-19) caused by a novel beta-coronavirus (SARS-CoV-2) broke out in Wuhan, China. Some patients rapidly progressed and suffered severe acute respiratory failure and died, making it imperative to develop a safe and effective vaccine to treat and prevent severe Covid-19 pneumonia. Based on detailed analysis of the viral genome and search for potential immunogenic targets, a synthetic minigene has been engineered based on conserved domains of the viral structural proteins and a polyprotein protease. The infection of Covid-19 is mediated through binding of the Spike protein to the ACEII receptor, and the viral replication depends on molecular mechanisms of all of these viral proteins. This trial proposes to develop universal vaccine and test innovative Covid-19 minigenes engineered based on multiple viral genes, using an efficient lentiviral vector system (NHP/TYF) to express viral proteins and immune modulatory genes to modify artificial antigen presenting cells (aAPC) and to activate T cells. In this study, the safety and immune reactivity of this aAPC vaccine will be investigated.

A large proportion of persons who have had COVID-19 have reported persisted symptoms as fatigue and dyspnea months post infection which affect activities of daily living. The aim of the study is to examine the feasibility and safety of a concentrated rehabilitation program with a mobile application follow-up for persons with persistent symptoms post COVID-19 infection. We will examine recruitment availability, adherence to the program, goal achievement, and resources requirements. Methods: A feasibility study with one group pre-post test design with 10-20 persons between 18-67 years, with persistent symptoms post COVID-19 will be included. The intervention is 3+ 1-2 days concentrated rehabilitation with a mobile application follow-up for 3 months. Following assessments wil be used: Cardiopulmonary exercise testing, lung function, functional performance tests, questionnaires regarding dyspnea, fatigue, anxiety, depression, work-status, health status, sleep behavior, physical activity level. Demographic data before and after the intervention will be presented. Focus group interview will be done with the participants. The interview will be analysed using systematic text condensation.

The study will assess whether Niagen, a safe dietary supplement, improves recovery of COVID-19 related symptoms in individuals who were infected at least 2 months prior to study entry ("Long-COVID" "Long-haulers"). 60% of participants will receive Niagen and 40% will receive PBO. Outcomes will consist of standardized cognitive, neuropsychiatric, physical, functional and biomarker assessments.

This will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions.

Participants with moderate depressive symptoms measured by PHQ-9 will be randomized to receive auricular acupuncture. The triple blinded procedure will be conducted in 12 sessions (6 weeks). The primary outcome is the response to the treatment 3 months after inclusion.

The overall purpose of the trial is to evaluate the efficacy and safety of possible combination antiviral therapy DAA (remdesivir + nirmatrelvir/r)∞ versus the reference monotherapy (nirmatrelvir/r alone) and to assess the efficacy and safety of increasing the nirmatrelvir/r course from 5- to 10 days in immunocompromised patients diagnosed with asymptomatic or mild to moderate COVID-19.

The goal of this proof-of-concept clinical trial is to determine whether cardiac rehabilitation improves exercise capacity and chronotropic (heart rate) response to exercise among people with Long COVID. The study will include individuals with confirmed SARS-CoV-2 infection, symptoms not present prior to COVID-19 that are persistent for at least 3 months after acute infection ("Long COVID"), and who have reduced exercise capacity less than predicted and reduced heart rate response during cardiopulmonary exercise testing (CPET). In addition to the primary outcome of change in peak VO2, secondary outcomes will include change in symptoms including autonomic symptoms (COMPASS-31), anxiety (GAD-7), depression (PHQ-9), endothelial function with brachial artery flow-mediated dilation, and satisfaction (net-promotor score).

COVID-19 is currently one of the serious public health challenges worldwide, and there is a great need to develop effective treatments. Paxlovid is a Pfizer-developed oral new drug for the treatment of COVID-19. Paxlovid, which is used to treat adult patients with mild to moderate COVID-19 who have high-risk factors for progression to severe disease, was conditionally approved for marketing in the United States and China in December 2021 and February 2022, respectively. Clinical trials have shown that this drug can significantly reduce the progression from mild to severe disease and the rate of hospitalization and mortality. However, due to the limitations of clinical trials in the subject selection, there is still insufficient knowledge about the efficacy and safety of Paxlovid in a real-world population. Relevant studies on this drug in real-world people, especially in Chinese populations, have not been reported. Therefore, this study was designed to investigate the efficacy and safety of Paxlovid on sufferers of COVID-19 through a retrospective, real-world analysis.
