Active clinical trials for "COVID-19"

Multi-center phase Ib study to evaluate the Modified Vaccinia Virus Ankara (MVA) vaccine against SARS-CoV-2 in seronegative (Part A) and previously SARS-CoV-2-vaccinated individuals (Part B).

This is a 4 dose study with 124 participants (7 adults ,117 children). Adults are considered to be participants 18 years of age or older. Participants are going to be enrolled based on conditions that make them immunocompromised. Participants are going to be followed up for 6 months after dose 4, and each participant is projected to be on the study for approximately 15 months. This study will be conducted in the United States, Brazil, Germany and Mexico.

Study into the effects of daily use of metformin and low-dose naltrexone (LDN) for 4 weeks to reduce symptoms, disease severity, and recovery time from COVID-19.

The study will evaluate the efficacy of Ad26.COV2.S in the prevention of molecularly confirmed moderate to severe/critical coronavirus disease-2019 (COVID-19), as compared to placebo, in SARS-CoV-2 seronegative adults in the double-blind phase and to describe COVID-19 outcomes, safety, and immunogenicity in the different study cohorts in open-label phase.

Study Rational Since December 2019, outbreak of COVID-19 caused by a novel virus SARS-Cov-2 has spread rapidly around the world and became a pandemic issue. First data report high mortality in severe patients with 30% death rate at 28 days. Exact proportions of the reasons of death are unclear: severe respiratory distress syndrome is mainly reported which can be related to massive cell destruction by the virus, bacterial surinfection, cardiomyopathy or pulmonary embolism. The exact proportion of all these causes is unknown and venous thromboembolism could be a major cause because of the massive inflammation reported during COVID-19. High levels of D-dimers and fibrin degradation products are associated with increased risk of mortality and some authors suggest a possible occurrence of venous thromboembolism (VTE) during COVID-19. Indeed, COVID-19 infected patients are likely at increased risk of VTE. In a multicenter retrospective cohort study from China, elevated D-dimers levels (>1g/L) were strongly associated with in-hospital death, even after multivariable adjustment. Also, interestingly,the prophylactic administration of anticoagulant treatment was associated with decreased mortality in a cohort of 449 patients, with a positive effect in patients with coagulopathy (sepsis-induced coagulopathy score ≥ 4) reducing the 28 days mortality rate (32.8% versus 52.4%, p=0.01). However the presence/prevalence of VTE disease is unknown in COVID-19 cancer patients with either mild or severe disease. Cancer patients are at a higher risk of VTE than general population (x6 times) and could be consequently at a further higher of VTE during COVID-19, in comparison with non-cancer patients. The exact rate of VTE and pulmonary embolism during COVID-19 was never evaluated, especially in cancer patients, and is of importance in order to understand if this disease needs appropriate prophylaxis against VTE. The largest series of cancer patients so far included 28 COVID-19 infected cancer patients: the rate of mortality was 28.6%. 78.6% of them needed oxygen therapy, 35.7% of them mechanical ventilation. Pulmonary embolism was suspected in some patients but not investigated due to the severity of the disease and renal insufficiency, reflecting the lack of data in this situation. The aim of the present study is to analyze the rate of symptomatic/occult VTE in a cohort of patients with cancer. Expected benefits Anticipated benefits of the research are the detection of VTE in order to treat it for the included patient. For all COVID-19 positive cancer patients it will enable to provide some guidelines and determine which patient are at risk for VTE and which will need ultrasound to detect occult VTE. Foreseeable risks Foreseeable risks for patients are non-significant because the additional procedures needed are ultrasound exam, and blood sample test. Methodology Retrospective and prospective (ambispective), multicentric study to evaluate the occurrence of venous thromboembolism during COVID-19 infection. Indeed, because the outbreak can end within the next 3-6 months, Investigators may not be able to answer the question if Investigators only focus on patients investigated prospectively. Investigators then decided to include patients from medical team who are already systemically screening patients with COVID-19 disease for VTE. Trial objectives Main objective To evaluate the rate of venous thromboembolism at 23 days during COVID-19 infection in cancer patients.

This study will assess the efficacy of AZD7442 for the post-exposure prophylaxis of COVID-19 in Adults.

This is a study to evaluate the efficacy, immune response, and safety of a coronavirus disease 2019 (COVID-19) vaccine called SARS-CoV-2 rS with Matrix-M1 adjuvant in adults aged 18-84 years in the United Kingdom. A vaccine causes the body to have an immune response that may help prevent the infection or reduce the severity of symptoms. An adjuvant is something that can make a vaccine work better. This study will look at the protective effect, body's immune response, and safety of SARS-CoV-2 rS with Matrix-M1 adjuvant in the study population. Participants in the study will randomly be assigned to receive SARS-CoV-2 rS with Matrix-M1 adjuvant or placebo. Each participant in the study will receive a total of 2 intramuscular injections over the course of the study. Approximately 15,000 participants will take part in the study. The first approximately 400 participants who meet additional criteria will receive a flu vaccine, in addition to the SARS-CoV-2 rS vaccine or placebo, as part of a sub-study. An effort will be made to enroll a target of at least 25% of participants who are ≥ 65 years of age, as well as prioritizing other groups that are most affected by COVID-19, including racial and ethnic minorities. Unblinding of treatment assignment may occur in order to allow a participant to make an informed decision regarding receipt of an already approved or deployed SARS-CoV-2 vaccine. Participants who choose to receive an approved or deployed SARS-CoV-2 vaccine as per UK government guidance will be encouraged to remain in the study for scheduled safety assessments.

The human immune system is enhanced by exposure to infrared radiation with the wavelength of 5 microns to 20 microns. Humans, at normal body temperature, radiate most strongly in the infrared at a wavelength of about 10 microns. Infrared energy sustains life and can be used to treat and prevent diseases, including Covid-19 infections. High temperature within the fever range obtained from infrared radiation causes the killer T-Cells to profilate. The Killer T-Cells improves ones immune system. The high temperature kills the Corona virus. In addition, multi-vitamins and minerals including high doses of Vitamin C, increase one's immune system. Vitamin C is an anti-oxidant, produces hydrogen peroxide and removes free radicals from the body. Pre-clinical trials conducted in Houston, Texas, using Vitality Therapy or the Bible Cure were successful in curing Covid-19 infections. It is therefore possible that Vitality Therapy or the Bible Cure can be used for the successful prevention and treatment of coronavirus infections.

This is a randomized, placebo-controlled study to assess the safety, PK profile, and efficacy of COVI-AMG in subjects with COVID-19.

The Michelle trial is expected to provide high-quality evidence around the role of extended thromboprophylaxis in COVID-19 and will help guide medical decisions in clinical practice.
