Filter by:A randomized, double-blind, placebo-controlled international multicenter clinical trial design will be adopted. A total of 29,000 subjects aged 18 years and above are planned to be recruited, including 750 subjects aged 18-59 years and 250 subjects aged 60 years and above in China; 21,000 subjects aged 18-59 years and 7,000 subjects aged 60 years and above will be recruited outside China. Safety and immunogenicity will be evaluated among the Chinese subjects, and efficacy, immunogenicity and safety will be evaluated among the subjects outside China. Among them, 750 subjects aged 18-59 and 250 subjects aged 60 and above from outside China and all subjects from China will be selected as the immunogenicity subgroup for immunogenicity bridging study. The IgG levels of SARS-COV-2 neutralizing antibody and RBD protein binding antibody will be detected by blood sampling before vaccination, 14 days and 6 months after full course of vaccination to evaluate the immunogenicity and immune persistence.
The gut immune system was shown as an effective target for inducing systemic immune signals against viruses. Oral administration of Travelan, an over the counter product which contains hyperimmune bovine colostrum was shown in preclinical studies to augment the anti-viral immune towards several strains of influenza viruses (RNA viruses). This study will evaluate the option that Trevalan may help improve the immune system reaction when introduced to COVID-19 proteins in-vitro. 5 healthy volunteers will receive a treatment regimen of 5 days with Trevalan. Before and after treatment, blood samples will be taken in order to test immune response towards viral proteins of the COVID-19 virus in vitro by measuring the number of T cell clone secreting IFNγ against viral antigens.
Clinical research study that evaluates the effect of Turkish Beam-Selective UV developed by RD GLOBAL ARAŞTIRMA GELİŞTİRME SAĞLIK İLAÇ İNŞAAT YATIRIMLARI A.Ş. use into Intravascular, Intrapulmonary, Intratracial, Intrarespiratory area. Bacteria, Fungal and Virus-based pathogens systematically to collect and evaluate specific clinical performance and safety data. This Clinical Research aims to investigate the effectiveness of the treatment group and control group mortality rates, intensive care hospitalization times, monitoring the virus load by PCR, and the treatment effectiveness of UVC application. This Clinical Research covers determining the treatment effectiveness and reliability of UVC application to patient groups, the details of which are determined in the protocol.
The BBV152 vaccine is being developed to prevent COVID-19, the disease resulting from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) infection. The study is designed to primarily evaluate the efficacy, safety, and immunogenicity of BBV152 to prevent COVID-19 for up to 1 year after the second dose of BBV152.
Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multi-Centre Phase II/III Adaptive Clinical Trial to Assess the Safety and Immunogenicity of Gam-COVID-Vac Combined Vector Vaccine for SARS-Сov-2 Infection in Indian Healthy Subjects.
This phase I trial evaluates the side effects and best dose of GEO-CM04S1 (previously designated as COH04S1), a synthetic modified vaccinia Ankara (MVA)-based SARS-CoV-2 vaccine, for the prevention of COVID-19 infection. COVID-19 infection is caused by the SARS-CoV-2 virus. SARS-CoV-2 has demonstrated the capability to spread rapidly, leading to significant impacts on healthcare systems and causing societal disruption. GEO-CM04S1 was created by placing small pieces of SARS-CoV-2 DNA (the chemical form of genes) into synthetic MVA, which may be able to induce immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The purpose of the Phase 1 study is to determine the safety and the optimal dose of the GEO-CM04S1 vaccine. The Phase 2 study is designed as a multi-center, double-blind, randomized, parallel, study to evaluate the safety profile of 2 dose levels of GEO-CM04S1 as a single booster shot to assess the immune response measured by the fold-increase in antibody against SARS-CoV-2 Spike protein at day 28 post-injection among healthy adult volunteers.
This Phase 2/3 study is a multi-portion design to confirm that the chosen formulation and dosing regimen of CoVLP has an acceptable immunogenicity and safety profile. The Phase 3 portion is an event-driven, randomized, observer blinded, placebo-controlled design that will evaluate the efficacy and safety of the CoVLP formulation compared to placebo. Subjects will be followed for safety and immunogenicity for a period of 12 months after the last vaccination.
Despite enormous progress in understanding COVID-19, there is little evidence that a solution, therapeutic or preventive, is close to being achieved. Repurposing of well known, widely available drugs represent an attractive approach to speed up availability of active treatments. Such substances as i.e. hydroxychloroquine and others, are already under investigation and in widespread off label use. For many reasons Methylene blue (MB), the oldest synthetic substance in medicine (1876 synthesized by BASF) is such a promising candidate for an active treatment against SARS-CoV-2 infected people and for COVID-19 patients.
This meta-trial is a prospective collaborative individual participant data meta-analysis of randomised controlled trials and early phase studies. Individual studies will be conducted in multiple countries, including Australia, the UK, the USA, Ireland, Argentina, Brazil and Egypt. Adult patients admitted to the hospital with confirmed SARS-CoV-2 infection, who do not require immediate mechanical ventilation, will be randomised to inhaled nebulised heparin or standard care for up to 21 days or until the patient has no respiratory symptoms. All studies will collect a minimum core dataset. The primary outcome for the meta-trial is the proportion of patients who receive invasive mechanical ventilation censored at day 28. Individual studies may have specific outcome measures in addition to the core set.
It is becoming increasingly evident that sleep plays an essential role for human health, and it represents an important biophysiological variable for athletes' well-being and recovery. The International Olympic Committee recently highlighted the importance of obtaining sufficient sleep volume and quality among athletes, but acute sleep deprivation is not unusual. Several factors, both endogenous and exogenous, are able to negatively influence sleep in athletes: body temperature, altitude, chronotype, training volume, anxiety, westward and eastward travels, and many others. Since December 2019, when a new coronavirus (SARS-CoV-2) was originally revealed by an ophthalmologist in Wuhan (Hubei province, China), a related severe acute respiratory syndrome - namely COVID-19 - has been spreading at a pandemic rate, putting global health systems under unprecedent pressure. Italy, as the first Western country tremendously hit by this disease outbreak, has become the iconic resilient outpost under international policymakers' attention. When initial clusters were identified, restrictive actions to curb isolated upsurges of infection were taken by the health region system of Lombardy, thereafter, were extended to all northern Italy and to the entire country. From February 21, when the first Italian COVID-19 case was diagnosed in southern Lombardy, to March 22, when Italian's government restrictions to contain the pandemic were extended, prohibiting all non-essential business activities and banning all movements of people nationwide, the country faced an unchartered scenario, from several standpoints, along with the psychosocial one. Inevitably, the Covid-19 outbreak has largely influenced the daily life of athletes too. Therefore, the primary aim of this study was to examine the differences in athletes' sleep quality, quantity and training volumes during the social confinement due to the virus outbreak. For this purpose, a survey will be used. This variables will be evaluated in 3 different time frames: 1) May 2020; 2) September 2020; 3) January 2021.
