Active clinical trials for "COVID-19"

This study looks at the safety and effectiveness of PF-07304814 in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either PF-07304814 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H6.

Leronlimab (PRO 140) is a humanized IgG4,k monoclonal antibody (mAb) that recognizes the C-C chemokine receptor type 5 (CCR5). Disruption of the C-C chemokine ligand 5 (CCL5)-CCR5 axis via leronlimab-mediated CCR5 blockade might prevent pulmonary trafficking of pro-inflammatory leukocytes and dampen pathogenic immune activation in coronavirus disease 2019 (COVID-19). The purpose of the study is to assess the safety and efficacy of leronlimab plus standard of care in patients hospitalized with COVID-19 pneumonia who are not requiring mechanical ventilation or extracorporeal oxygenation (ECMO).

This is a pilot study in 24 subjects where half will be randomized to 10 treatments with hyperbaric oxygen (HBO). It will primarily study pulmonary sequelae with imaging and physiological measurements (low dose chest computer tomography (CT), Ventilation/perfusion with magnetic resonance imaging (VA/Q MRI), cardiopulmonary exercise testing with pulse oximetry (SpO2) and spirometry including diffusion capacity for carbon monoxide (DLCO). The target patient group will be previously healthy whom have had covid-19 with lingering symptoms past 12 weeks of recovery from the acute phase.

The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.

This retrospective study aims to perform a medication risk stratification using drug claims data and to simulate the impact of the addition of various repurposed drugs on the Medication Risk Score (MRS) in a health insurance population. Our clinical tool would enable us to identify potential multi-drug interactions and potentially reduce the risk of adverse drug events (ADE) developing in these patients infected with COVID-19.

Periodontal disease is a chronic condition affecting the teeth and surrounding support structures, characterized by tooth loss and alveolar bone loss. Sanative therapy (ST) is the gold standard non-surgical treatment for periodontal disease and involves mechanically removing the subgingival bacteria from the periodontal pockets. Regular periodontal maintenance appointments are needed to maintain periodontal health after ST. Moreover, the periodontal health of individuals not requiring ST is also dependent on regular hygiene appointments. Due to Ontario's March 2020 COVID-19-related clinic closure for approximately 3 months along with a reduced numbers of appointments available due to guidelines of professional bodies and public health beyond this period of time, many appointments were considerably delayed or cancelled. The effects of this disruption to periodontal health in male and female patients who have undergone ST and continue with maintenance appointments or who attend for regular hygiene appointments have not yet been investigated.

Many people who have had COVID 19 continue to experience symptoms long after they have recovered from the acute infection. This study will examine the clinical symptoms of people with "Long COVID" and measure various markers of inflammation in their blood.

Brain injury is one of the complications in COVID-19 intensive care unit (ICU) survivors, though the precise underlying mechanism is unclear. It is likely caused by a combination of prolonged hypoxia, a massive systemic inflammatory response, direct infection of the brain and small vessel vasculitis in combination with widespread hypercoagulopathy and thrombosis. Using novel MRI techniques, blood-brain barrier (BBB) permeability, as well as other microstructural and microvascular properties of the brain tissue, will be assessed non-invasively in COVID-19 ICU survivors approximately one year after ICU admission and compared to serial clinical and laboratory measurements of hypercoagulation and inflammation during the (ICU) admission. This study aims to relate factors of hypercoagulability, inflammation or general illness itself (all during ICU admission) to microstructural and microvascular abnormalities on follow-up brain advanced 3T and 7T MRI in COVID-19 ICU survivors. In addition, neuropsychological tests and an objective smell/taste test will be used to evaluate neuropsychological status and sense of smell/taste. By gaining more insight into the pathogenesis of brain injury, the treatment of COVID-19 patients in the acute phase might be improved.

A pneumonia of unknown cause detected in Wuhan, China, was first reported in December 2019. On 08 January 2020, the pathogen causing this outbreak was identified as a novel coronavirus 2019. The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020. On 12 February 2020, the virus was officially named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the WHO officially named the disease caused by SARS-CoV-2 as coronavirus disease 2019 (COVID-19). On 11 March 2020, the WHO upgraded the status of the COVID-19 outbreak from epidemic to pandemic, which is now spreading globally at high speed. There are currently few licensed vaccines to prevent infection with SARS-CoV-2 or COVID-19 and the duration of response is unknown. Given the rapid transmission of COVID-19 and incidence of disease on a worldwide basis, the rapid development of effective vaccines with sufficient protection and duration of response is of utmost importance. IAU has developed a thermally stable plasmid DNA (pDNA)-based vaccine candidate using a platform approach that enables the rapid development of vaccines against emerging viral diseases, including SARS-CoV-2. The pDNA vaccine developed by IAU is a synthetic, codon-optimized, encode either the full-length Spike (S) gene or S1 domain of SARS-CoV-2 as genes of interest. Here, we aim to test a synthetic, codon optimized pDNA encoding S.opt.FL as vaccine candidate against COVID-19. A key advantage of pDNA vaccine is that multiple immunization can be used without the limitations of anti-vector responses. This study is intended to investigate the safety, immunogenicity, and tolerbilty of this prophylactic vaccine against COVID-19 administered as intramuscular immunization (i.m.).
