Active clinical trials for "COVID-19"

Why is the research needed? The pandemic known as COVID-19 is now spreading across the world with currently (April 10, 2020) more than 1 115 530 active cases and 96 791 deaths. In most affected countries the current goal is to 'flatten the curve' of the epidemic since there is no health care system that is able to treat an extremely high volume of patients all at once. There is a need for immediately applicable treatments for the patients at highest risk, which gains time until targeted therapies become available. A key feature in the pathomechanism of the disease is that the virus elicits an immunological over-reaction in the human body termed 'cytokine storm'. In susceptible patients this hyper-inflammation itself is a significant burden and may even inhibit the body to generate antibodies against the virus in adequate quantities. Therefore, identifying the subset of patients with excess cytokine response and supplementing them with convalescent plasma from recovered donors may be a life-saving treatment option. What is our study about? In light of recent promising data on plasma therapy in the treatment of COVID-19 and other viral epidemics, there is a need for better understanding the cytokine response to the virus in order to better characterize the target population for convalescent plasma therapy. Our hypothesis is that convalescent plasma transfusion from healthy donors who recovered from SARS CoV-2 is able to reduce the cytokine storm in addition to replenish the patient's own antibodies in the acutely infected phase of the disease. A plasmapheresis donation of 400ml will be performed in subjects who recovered from COVID-19 and who are otherwise eligible for plasma donation. The sample will be tested for anti-SARS CoV-2 neutralizing antibody titers and those that reach the level of 1:320 will be processed for transfusion at the Hungarian National Transfusion Service. Recipients will be COVID-19 patients requiring hospitalization regardless of the severity of the disease or other co-morbidities. A blood-type matched transfusion of 200 ml convalescent plasma will be infused in a single sitting through an iv. infusion of 4 hours. Recipients will be followed up at days 1, 3,7,12, 17, 28 for clinical symptoms, antibody levels and cytokine response.

Observe the efficacy and safety of G1(Sildenafil citrate tablets) in patients with COVID-19 under clinical actual diagnosis and treatment conditions

This is a Italian, superiority, open label cluster-randomised, interventional clinical trial aimed at assessing whether the treatment with Hydroxychloroquine can reduce the percentage of symptomatic subjects compared to observation only in household members/contacts of COVID-19 patients (Group 1) and if the treatment with Hydroxychloroquine could be introduced in early phase COVID-19 population (Group 2). The participants will be randomised to receive either: Arm A) hydroxychloroquine vs Arm B) Observation (2:1 randomisation).

This study will determine the effectiveness of training church health ministers to educate their congregations about the safety and efficacy of COVID-19 vaccines and booster shots for decreasing vaccine hesitancy and improving testing knowledge in underserved Black communities.

This is a randomized, double-blinded, placebo-controlled, dose-escalation study to valuate the safety and immunogenicity of RH109 as booster at 2 dose levels for ealthy adults who have received homologous or heterologous vaccination with 3 doses of COVID-19 inactivated and/or mRNA vaccine(s). The purpose of this study is to evaluate the safety and immunogenicity of RH109 as booster for healthy adults who have received homologous or heterologous vaccination with 3 doses of COVID-19 inactivated and/or mRNA vaccine(s).

Introduction: The COVID-19 epidemic and related mutations, which affect the whole world, continue to increase globally. In particular, this crisis adversely affects school-age children's quality of life. Method: The study was carried out between February and April 2022 following the experimental research criteria with the pretest-posttest-retest control group. The research population consists of 4th-grade primary school students studying in schools affiliated with the Siirt Directorate of National Education. The sample consists of 148 students studying in the 4th grade at two schools deemed suitable for the conduct of the study. Data were collected using data collection materials, the Descriptive Questionnaire, and the General Child Quality of Life Scale. Results: The mean age of all students participating in the study was 10.53±2.60, 53% of the students were girls, and 47% were boys. It has been determined that 36.0% of the Students have not received any training on COVID-19 before, 32.4% of them did not take precautions to defend themselves from COVID-19 disease, and it is not possible to protect 48.4% of them from COVID-19 disease even if adequate precautions are taken. It was found that the difference between the pretest, posttest, and retest mean scores of the Students in the experimental group on the quality of life scale was statistically significant (p < 0.05). It was determined that the mean of life quality increased immediately after the training but decreased in the measurements one month later. Conclusion: Education to be given to school-age children should be developed with animation-supported programs.

Rapid, accurate diagnosis of Covid-19 would greatly help to improve clinical management of patients presenting with symptoms of possible Covid-19. Currently results of the standard test for the virus take 2-3 days to be reported. Watford General Hospital has imported rapid antibody tests manufactured by Zuhai Livzon Diagnostics Inc in China and our team would like to evaluate their accuracy and clinical usefulness. The test involves taking a drop of blood from the patient (either from a venous blood sample taken for other blood tests, or from a fingerprick). This is applied to a test strip (similar to a pregnancy test) and two drops of diluent are added. If the patient has antibodies to Covid-19, two lines appear on the test strip (like a positive pregnancy test) whereas if the patient has no antibodies, only one line appears (like a negative pregnancy test). There are two different types of antibody: IgM is produced early in the course of the illness (day 7-14) and then IgG is produced later and continues to be present, probably for months or years. There are two test strips, one for each of these types of antibody. In this study we aim to evaluate the accuracy of this new test, in three groups of patients. Firstly those with proven Covid-19 and at least 7 days after the onset of their illness. We aim to recruit 200 patients in total: at least 138 patients with 10 or more days of symptoms, plus a subgroup of up to 62 patients with 7-9 days of symptoms (to explore the usefulness of the test earlier in the course of illness). The second group of 250 patients will be those hospital staff who report symptoms possibly caused by Covid-19 and are receiving a standard antibody test. The third group of patients will be those followed up in a "virtual hospital" for clinically suspected Covid-19 who had never been tested with a standard PCR test. As we are not sure of the accuracy of the new test, its results will not be used to make decisions about treatment for the patient. This study will enable us to discover rapidly whether the new test is accurate, and if so we will conduct further studies to assess how it can help to improve management of patients with suspected Covid-19.

In December 2019, a pneumonia due to a novel coronavirus (SARS-CoV-2) emerged in the city of Wuhan, in China. In a few weeks, the number of confirmed cases of SARS-CoV-2 infection has dramatically increased, with almost 150'000 cases and more than 6'000 reported deaths on March, 16th 2020. Little is known on the rate of human-to-human transmission of this new coronavirus SARS-CoV-2 in the community and within the hospital. Depending on the country, contact subjects considered to be at high or moderate risk of SARS-CoV-2 are, either isolated at home for a period of time defined by the health authorities or, on the contrary, continue their professional activity on the condition that they adopt measures to prevent transmission to those around them. In most European countries, healthcare workers adopt this second option. In all cases, it is most often recommended that contact persons monitor their state of health and communicate it to the persons dedicated to this action. Whether such subjects become spreaders of the virus is not known, nor is the proportion of viral spreader who will develop a symptomatic infection.

International guidelines suggest the administration of empirical broad-spectrum antibiotics for suspected bacterial co-infection in COVID-19 critically ill. However, data on associated respiratory infections is rare and antimicrobial stewardship interventions promoting antibiotic savings are non-existent in this context. The main objectives of the trial are: to evaluate the rate of co-infections among COVID-19 critically ill to evaluate the added value of a a rapid molecular diagnostic tool (FA-PNEU) to detect the presence of co-infecting pathogens in order to rapidly tailor the patient's antibiotic treatment

This study is a interventional study that present minimal risks and constraints to evaluate the presence of novel coronavirus (SARS-CoV-2) or antibodies among individuals living in households where there is a confirmed coronavirus case in order to provide useful information on the proportion of symptomatic forms and the extent of the virus transmission in tropical regions such as French Guiana, Guadeloupe and New-Caledonia.
