Active clinical trials for "COVID-19"

The purpose of this study is to assess the antibody response to COVID-19 vaccination in a cohort of patients with sickle cell disease (SCD) and to assess vaccine and SCD related complications around the time of vaccination.

To fast respond the coronavirus disease of 2019 (COVID-19) pandemic, the Indonesian government has launched "Vaksinasi Gotong Royong" (a mutual cooperation vaccination program) in which any company/legal entity/business entity may purchase vaccines to be given free of charge to their employees and families of employees (The Indonesian Ministry of Health, 2021). Vaccines provided for this program include the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inactivated vaccines produced by Sinopharm. The Indonesian National Agency of Drug and Food Control (NADFC) has issued an Emergency Use Authorization (EUA) for several COVID-19 vaccines, including the SARS-CoV-2 vaccine (Vero cell) inactivated produced by Sinopharm (NADFC, 2021). Following EUA, Kimia Farma Indonesia as the holder of EUA has the obligation to monitor the safety and effectiveness in Indonesian population.

This survey will be conducted for the subjects who participate in the priority survey (cohort survey) conducted by the Scientific Research Group of the Ministry of Health, Labour and Welfare at the initial stage of administration of the COVID-19 vaccination. The present study aims to collect information on serious adverse events or COVID-19 infection observed from 28 days after the last vaccination of VAXZEVRIA up to 12 months after the last vaccination and to evaluate the long-term safety of this vaccine.

The purpose of this study is to evaluate the efficacy and safety of XAV-19 drug in patients with moderate-to-severe COVID-19.

COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has a devastating effect on human lives, including over 6.6 million death as of November 2022. Furthermore, many individuals continue to experience persisting sequelae after the initial infection. Little is known about the impact of undergoing COVID-19 hospitalisation. Hence, the investigators propose an observational longitudinal study in a cohort of COVID-19 survivors after hospital discharge, to examine their perspectives on their health, health-related quality of life, and persistence of common COVID-19 symptoms, such as fatigue, dyspnoea and anxiety. Potential influencing socio-demographic and biological factors will additionally assessed.

The purpose of this research study is to see if participants who have SARS-CoV-2 and low levels of AT3 in the blood will benefit by being given AT3.

Contrasting hypotheses, including that of a protective role of nicotine, have been generated concerning the association between smoking and the occurrence of COVID-19 infection. The question has attracted a lively scientific and public debate. However, the studies conducted so far are based on clinical samples, with a majority of hospital case series, thus most likely suffering from bias due to selection. The investigators propose to conduct an analysis of the potential causal association between smoking or the use of the Swedish smokeless tobacco snus and the occurrence of COVID-19 using data from a newly identified retrospective cohort in Sweden. Information on tobacco use will be extracted by public dental clinic records in Stockholm Region between October 2015 and January 2020. Information on diagnoses of COVID-19 will be obtained through record linkage with health care registers of inpatient and outpatient care during the period February 2020-August 2021. Socio-demographic information will be accrued from the register of the total population in Stockholm Region (Statistics Sweden). The risk of COVID-19 for tobacco users compared to non-tobacco users will be calculated as a measure of association adjusting for potential confounders.

The purpose of this study is to evaluate the safety and tolerability of single ascending IV dose administrations of GIGA-2050 in patients hospitalized with COVID-19.

This is a 2 part study where the first part (Phase 1) evaluates the safety of XVR011 and aims to identify the recommended Phase 2 dose. The second part (Phase 2) follows after the part 1 and evaluates whether XVR011 added to standard of care in patients hospitalised for mild to moderate COVID-19 is a safe, well tolerated, and effective treatment. Part 1 (Phase 1) is completed as per protocol. The sponsor does not intend to start Part 2 (Phase 2) due to change in company strategy for phase 2 design.

The purpose of this study is to determine to what extent a short systemic steroid therapy with estradiol and progesterone, administered early to hospitalized and confirmed COVID-19 positive patients of both sexes in addition to standard of care (SOC) can reduce the severity of symptoms and outcomes compared to SOC alone.
