Filter by:This study is randomized, double-blind (blinded for the trial subject and the study physician), placebo-controlled trial in the parallel assignment of the immunogenicity, and safety of the Gam-COVID-Vac combined vector vaccine against the SARS-CoV-2-induced coronavirus infection in adults in the SARS-СoV-2 infection prophylactic treatment.
All health care workers at the Department of Anesthesiology and Intensive Care at UMC Ljubljana will be tested for SARS-CoV2 with nasal swab test and blood withdrawal for SARS-CoV2 antibodies. At the same time a questionnaire with epidemiological anamnesis, risky contacts and the use of personal protective equipment will be fulfilled.
Currently, SARS-CoV-2 the novel member of the corona virus family, affecting the world leading to COVID-19 disease. It can result life-threatening condition by developing severe acute respiratory distress syndrome (ARDS). Based on previous evidence a group of patients with severe COVID-19 develop a cytokine storm syndrome which leads to hyper-inflammation lung tissue damage. Supportive care is the current management of COVID-19 is and management of ARDS as a main cause of mortality has been remained challenging. Therefore, an urgent effective treatment of COVID-19 regarding hyper-inflammation mechanism is required. Currently, development of novel anti-viral agents and vaccines are the main issues. However, it needs long time, from months to years, until suitable new medications and vaccines have been developed. An immune-modulatory tetra deca peptide (14-mer peptide) named Human Ezrin Peptide 1 (HEP-1) (trade name Gepon) was introduced by the group of Ataullakhanov in Russia. Regarding its proved anti-viral and anti-inflammatory effect, Russian authorities approved Gepon for treatment of ulcerative colitis treatment and Hepatitis -C. In this regard, it seems that Hep-1 is a very safe immune-modulatory agent which can be effective in the management of COVID-19 infection without any adverse effect for the patient.
An observational study is carried out in the university population of the University of Salamanca to know the impact of the COVID-19 pandemic and the influence of physical exercise on the severity of symptoms.
The purpose of this Pilot Study is to establish a hypothesis of whether or not intravenous immunoglobulin (IVIG) may impact the hospital length of stay, if started within 48 of mechanical ventilation in patients infected with SARS-CoV-2 virus.
Protocol summary Title A Prospective, randomized, adaptive phase II/III clinical trial, controlled, open-label, chemoprevention, 3-arms, parallel, multi-centred, to A Prospective, randomized, clinical trial, controlled, open-label, 3-arms, parallel, multi-centred, chemoprevention of COVID-19: Hydroxychloroquine Post Exposure Prophylaxis For COVID-19 Study Periods & Duration of Treatment Study Duration: 6 months Approval (IRB and regulatory bodies) 1 month Recruitment and follow-up: 3 months Analysis, report writing and submission of publications 1 month This study is a parallel study of one period with an expected duration of treatment (for each subject) of 28 days, Objectives - To evaluate if hydroxychloroquine with the proposed dose can provide potent chemoprophylaxis against the development of COVID-19 positive patients in subjects who had primary exposure to COVID-19 positive patients. - To measure the incidence of potential adverse drug reaction rates for giving hydroxychloroquine for prevention of COVID-19 amongst close contacts - To provide early analysis of results and redefine sample size accordingly. - identifying subjects most likely to benefit during the phase II and focusing recruitment efforts on them during phase III - stopping one arm or the whole trial at an early stage for success or lack of efficacy based on phase II study results Design Prospective, Randomized, open-label, three-arm, parallel, adaptive phase II/III controlled study in which subjects will be randomly assigned in a 1:1:1 ratio as per the following: Arm-1: hydroxychloroquine 800mg (400mg twice daily) given orally on day 1, (loading dose) hydroxychloroquine. Then 400mg (200mg 2 tablets) on day 2,3, 4 and 5. Arm-2: hydroxychloroquine 400mg (200mg twice daily) Given orally first day (loading dose), then 200mg once daily on day 2,3, 4 and 5. Arm-3: No Intervention- SARS-CoV-2 surveillance Standard control measures in the country of interest such as self isolation, good personal hygiene and good nutrition.
This study is a multicenter, randomized, open, parallel-controlled study. Qualified subjects will randomly be assigned to the experimental arm or the control arm according to the ratio of 1:1, with age (> 60 years or ≤ 60 years), smoking status (yes/no) and forced expiratory volume in one second/prediction (FEV1 %pred > 60% or ≤ 60%) as the random stratification factors.
1.5. Why this clinical study? The prevalence of seropositivity following SARS-CoV 2 infection might have its own potential benefits in terms of predicting the end of pandemic and the validity of herd immunity. It is not clear if SARS-CoV 2 infection would have a long-lasting antibody-mediated immunity, and if the antibodies' persistence is dependent on disease severity.depends on the severity of illness. If evidence is provided about the persistence of antibodies that is reflective of the protective immune response, serodiagnosis will be an important tool to identify individuals with various risk for infection, and those who are in need of receiving the forthcoming vaccines. The here proposed prospective clinical study will test the prevalence of seropositivity following SARS-CoV 2 infection in critically ill patients compared to those who do not require intensive care unit (ICU) admission or invasive ventilation with respect to the IgM and IgG levels.
Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.
This research aims to investigate the incidence, clinical condition, mode of transmission and laboratory data of women and their babies, who were exposed to COVID-19 infection during pregnancy. This project will consist of 4 subprojects, being that Subprojects 1 and 2, will be of the observational, longitudinal type of prospective Cohort; Subproject 3 will be of prevalence; Subproject 4 will be case-control. Subproject 1- This study aims to assess periodontal condition and quality of life before and after delivery of women with excess weight gain or not, with exposure to coronavirus-sars-cov2. Subproject 2- Identify the proteins differentially expressed in saliva associated with COVID-19 infection during the 3rd trimester of pregnancy in obese and eutrophic patients. Subproject 3- Assess the prevalence of congenital syndrome in babies associated with the presumed maternal infection with SARS-CoV-2. Subproject 4- Case-control study in which newborns are submitted to clinical examination, being a group with congenital malformations and their respective controls and an interview with the mother was carried out.
