Filter by:The purpose of the study is to evaluate whether bemnifosbuvir (BEM) is effective and safe in adults with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible subjects will be randomly assigned (by chance) to receive BEM or matching placebo orally for 5 days. Co-administration of locally available standard of care (SOC) is allowed. The total duration of the study is 60 days.
Fatigue is a common symptom and can be the most distressing symptom of a range of medical conditions. This Ecological Momentary Assessment study will investigate lived experiences of fatigue in detail in individuals with myeloma, long COVID, heart failure, and in healthy controls without fatigue. Participants will wear ECG patches and wrist-worn sensors that measure heart rate variability, activity levels, posture, and other parameters. They will self-rate their levels of fatigue four times daily and on-demand (when fatigue levels are noticeably good or troublesome). They will participate in an end of study interview and will have an optional feedback session with a researcher to make sense of the data they have provided.
The main objective of the study is to evaluate the effectiveness of the vaccine against covid-19, recommended by the national immunization program. This is a multicentric, observational, case-control study. Participants Cases with the disease will be compared to Control Participants, that is, without the disease, regarding the vaccination history for Covid-19.Complementarily, an evaluation of cellular and humoral immunity will be carried out in a sample of both case and control participants, taking into account the vaccination history.
The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.
This study will investigate whether pregnant and lactating women can develop similar protective immunity as non-pregnant women against Coronavirus Infectious Disease 2019 (COVID-19) upon vaccination, without safety issues. Immunogenicity and safety of all currently licensed COVID-19 vaccines that are administered to pregnant and lactating women in Belgium will be studied.
In collaboration with community partners, this study will identify disparities and dynamics of COVID-19 testing and infections in three Texas regions; and implement a multilevel intervention that increases access to testing and referrals to follow-up care among vulnerable populations. Using a three-arm group-randomized controlled trial, this study will assess the impact of multi-level interventions influencing motivation and access to testing. The outcomes of this study are measured at the population level and no individual data will be gathered. Analyses of de-identified PHI data from local and regional health departments on COVID testing and infection rates will be used to assess intervention outcomes.
This clinical trial is designed to assess the safety, tolerability and immunogenicity of a single dose of ChulaCov19 BNA159 and ChulaCov19 BNA159.2 vaccines as a booster dose, given at least 3 months after receipt of a previous booster dose of any authorized/approved COVID-19 vaccine.
Using detailed serial cross-sectional estimates of the age-specific distribution of SARS-CoV-2 Omicron variant-specific antibody positivity levels, we derived age-specific infection attack rates and age-specific population immunity levels and tracked the magnitude of individual-level and population-level waning immunity over time. Our findings will inform health policy makers on devising future public health and social measures and vaccination guidance in response to the ongoing COVID-19 pandemic.
It is a single center, randomized, open-labeled, exploratory clinical study to evaluate the safety and immunogenicity of Recombinant SARS-CoV-2 Fusion Protein bivalent Vaccine V-01-B5 as a second booster in adults aged 18-59 years after vaccinated with 3-dose of inactivated vaccines.
It is a single center, randomized, open-labeled, blind endpoint evaluation, exploratory clinical study to evaluate the safety and immunogenicity of bivalent vaccine V-01D-351 as a booster.
