Active clinical trials for "COVID-19"

The objective is to evaluate the safety and immunogenicity of AZD1222 given in combination with (either before or after) rAd26-S, for the prevention of COVID 19 in adults ≥ 18 years of age.

The primary aim of this study is to examine whether lower-risk activities displace participation in higher-risk behaviors during COVID-19. Investigators will test this aim by promoting specific activities that are expected to be low-risk when it comes to COVID-19 transmission (e.g., participating in a hiking challenge) and assessing impacts on participants' activity choices. Investigators also aim to describe adults' activity participation during COVID-19 generally and to examine secondary outcomes, including reported stress and sleep.

TAK-019 is a vaccine in development to protect people against Covid-19. The main aims of the study are to learn if TAK-019 can protect people from Covid-19 and to check for side effects from TAK-019. At the first visit, the study doctor will check if each person can take part. Those who can take part will be chosen for 1 of 2 treatments by chance. Participants will either receive an injection of TAK-019 or a placebo in their arm. In this study, a placebo will look like the TAK-019 vaccine but will not have any medicine in it. 3 times as many participants will receive TAK-019 than placebo. Participants will receive 2 injections of TAK-019 or placebo, 21 days apart. Participants will be asked to record their temperature and any medical problems in an electronic diary for up to 7 days after each injection. During the study, participants will visit the clinic for regular check-ups, blood tests, and sometimes for nose swab samples. When all participants have attended a clinic visit 28 days after their 2nd injection, the study sponsor (Takeda) will check how many participants have made enough antibodies to protect them against Covid-19. The participants will stay in the study for up to 12 months after they have had their 2nd injection. During this time, the study doctors will continue to check how many participants have made enough antibodies to protect them against Covid-19. Also, they will check if participants have any more side effects from TAK-019 or the placebo.

As no curative treatment for SARS-CoV-2 is currently available, most public health measures to contain the pandemic are based on preventing the spread of the pathogen. The virus is transmitted by the respiratory route and by direct contact with contaminated surfaces and subsequent contact with nasal, oral or ocular mucosa. Although patients with symptomatic coronavirus disease 2019 (COVID-19) have been the main source of transmission, observations suggest that asymptomatic and incubating patients also have the ability to transmit SARS-CoV-2. Angiotensin II converting enzyme (ACE2) is the main cellular receptor for SARS-CoV-2, which interacts with the spike protein to facilitate its entry. ACE2 receptors are highly expressed in the oral cavity and present at high levels in oral epithelial cells. The mean expression of ACE2 was higher in the tongue compared to that in other oral tissues and it has been found to be higher in the minor salivary glands than in the lungs. These findings strongly suggest that the oral cavity and specifically the saliva may be a high-risk route for SARS-CoV-2 infection. Thus, strategies reducing salivary viral load could contribute to reduce the risk of transmission. Furthermore, studies using macaques as animal models have shown that SARS-CoV persists for two days in oral mucous membranes before its diffusion to the lower respiratory tract. This offers an interesting preventive and therapeutic window of opportunity for the control of this disease. For this reason, the use of mouthwashes with antiseptics that have virucidal activity can be a simple preventive strategy that could easily be applied both by infected patients before being examined by sanitary personnel and in the general population. This study is a multi-centered, blinded, parallel-group, placebo-controlled randomised clinical trial that tests the effect of four different mouthwashes (CPC, chlorhexidine, povidone-iodine and H2O2) in the salivary viral load of SARS-CoV-2 measured by qPCR at three different timepoints. A fifth group of patients using a distilled water mouth rinse is used as a control. Viral particles per ml of saliva are quantified at baseline and 30, 60 and 120 minutes after a 1-minute mouth rinse with the antiseptic or water. Our study aims to test whether any of these standard oral antiseptics appear to diminish viral load in saliva and could therefore be used as a strategy to reduce transmission risk in clinical and social settings.

This is a randomized, double blind, placebo parallel-controlled phase III clinical trial to evaluate the efficacy, immunogenicity and safety of the inactivated SARS-CoV-2 Vaccine (Vero cell) in Argentine healthy population aged between 18 and 85 years old.

The primary objective of Part 1 (Single Ascending Dose) is to assess the safety and tolerability of anti-SARS-CoV-2 IgY when given as single-ascending doses administered intranasally to healthy participants. The primary objective of Part 2 (Multiple Dose) is to assess the safety and tolerability of anti-SARS-CoV-2 IgY when given as multiple doses administered intranasally to healthy participants. A secondary objective is to assess the pharmacokinetics of anti-SARS-CoV-2 IgY when given as multiple doses administered intranasally to healthy participants. Safety will be evaluated using adverse event (AE), physical examination (including vital signs), electrocardiogram, and clinical laboratory data. Pharmacokinetics will be evaluated by serum anti-SARS-CoV-2 IgY concentration.

Kit for reading vital signs (thermometer, wrist blood pressure device, finger oximeter) and with study drug is overnighted to qualified subjects with early symptoms of COVID-19. Subjects take a 20-milligram (mg) tab of famotidine or matching placebo twice a day, increase to 1 tablet every 8 hours if not better the 2nd day, and continue same for 30 days. Vital signs, symptoms, compliance etc are rechecked daily for the 30 days and once again 60 days after starting study drug. Consent, baseline, and follow-up are handled via internet plus calls/texts/virtual visits from study nurse or doctor as needed for clarifications and compliance.

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.
