Filter by:The COVID-19 pandemic has disproportionately affected American Indian (AI) and Latino communities, and these groups also have increased risk of poor prognosis due to high rates of chronic disease such as diabetes, cardiovascular disease, and cancer. In the northwestern United States, AI and Latino communities already face significant disparities in health care access, which have been further exacerbated by the COVID-19 pandemic. In the proposed study, Protecting Our Community: A Pragmatic Randomized Trial of Home-Based COVID Testing with Native American and Latino Communities, the investigators will leverage our long-term community-based participatory research partnerships to test the hypothesis that home-based testing will be feasible, impactful, and better-accepted using active delivery of test kits by trusted community health educators in two vulnerable, high-risk rural communities. Our two long-term partner communities are the Flathead Indian Reservation of the Confederated Salish and Kootenai Tribes in Montana, and the Yakima Valley of Washington, a large Latino community. The investigators will determine the cultural, social, behavioral, and economic barriers to home-based SARS-CoV-2 testing; culturally adapt and enhance home-testing educational materials and create home-testing instructional graphics and YouTube videos; conduct a 2-arm pragmatic randomized trial of active (delivered by community health educator) vs. passive (without community health educator) home-based testing kits (n = 200/community) for testing completion; and create a model for community-driven testing protocols that can have significant impact for increasing home-based testing uptake among AI and Latino communities nationally. This work will enable underserved AI and Latino communities to take full advantage of the coming wave of rapid point-of-care home tests and decrease the significant impact of COVID-19 in their communities.
This is an open-label study to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1273 Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) vaccine in adults with a kidney or liver solid organ transplant (SOT) and in healthy adult participants. The primary goal of the study is to evaluate the safety of mRNA-1273 and the serum antibody (Ab) responses obtained 28 days after the last dose of mRNA-1273.
The primary objectives of this study are to evaluate the safety and reactogenicity profile after 1 and 2 dose administrations of investigational SARS-CoV-2 mRNA vaccine CVnCoV, and to evaluate the humoral immune responses 14 days after 2 dose administrations of CVnCoV.
This is an open-label, two arm interventional exploratory study to evaluate the safety and efficacy of 5-ALA-Phosphate-SFC during the vaccination of subjects against SARS-CoV-2 (COVID-19) virus infection to define the safety and to activate the immune system during SARS-CoV-2 vaccination. The primary objective of this study is to determine the safety of a 4 week daily oral administration of 5-ALA-Phosphate + SFC in subjects vaccinated with COVID-19 Vaccine
The use of amantadine in the prevention of progression and treatment of COVID-19 symptoms in patients infected with the SARS-CoV-2 virus. Multicenter randomized, double-blind, placebo-controlled, non-commercial clinical trial
The primary objective of this study is quantify the transmission risk posted by SARS-CoV-2 in pre/asymptomatic infected children in order to inform the public health response to the COVID-19 pandemic.
To investigate the incidence of SARS-CoV-2 infections after vaccination, to monitor the development of SARS-CoV-2 antibody levels after vaccination and to compare this in relation to both previous health & disease, previous antibody responses and in relation to future disease occurring after vaccination.
Approximately 28,000 subjects will be enrolled in this trial. Eligible subjects will be stratified by age (<60 years of age and ≥60 years of age, the proportion of elderly people ≥60 years old is planned to be ≥25%) and randomly assigned into the study group and the control group at a ratio of 1:1 (14,000 in each group) to be intramuscularly administered with the investigational vaccine or placebo in a 2-dose regimen at an interval of 28 days. The experimental vaccines will be cross-vaccinated after available data of the investigational vaccine show that expected efficacy and good safety have been achieved (i.e., subjects in the study group will be vaccinated with placebo and those in the control group will be vaccinated with the investigational vaccine in the same schedule as stated above ). After the completion of the second dose for crossover vaccination, subjects will be followed up for 12 months for safety observation. An immunogenicity subgroup (n≥3000) and a reactogenicity subgroup (n≥6000) will also be included in this trial to evaluate the humoral immunity induced by the investigational vaccine and the solicited adverse events observed within 7 days post immunization. All enrolled subjects will be followed up for the evaluation of protective efficacy as well, which will be primarily characterized by the incidence rate (person-year) of COVID-19 cases collected from 14 days after complete series. Adverse events will be collected over 0-28 days after each vaccination and serious adverse events will be collected from Dose 1 through 12 months post complete series.
This is a phase I, double-blind, placebo-controlled,dose-ranging clinical trial in healthy males and non-pregnant females, 18 to 55 years of age. The trial is designed to assess the safety, reactogenicity, and immunogenicity of VACCINE RNA MCTI CIMATEC HDT(HDT-301), which is a novel Lipid-Inorganic Nanoparticle (LION) formulated replicating RNA-based vaccine that encodes for a full-length spike (S) protein of the SARS-CoV-2 virus. As a replicating mRNA vaccine, VACCINE RNA MCTI CIMATEC HDT(HDT-301) has the potential to allow the advantages of dose sparing, and possibly administration as a single dose, compared with other mRNA platforms. Enrollment will occur at one domestic site. A total of 90 healthy subjects will receive multiple dosages of intramuscular (IM) injections of VACCINE RNA MCTI CIMATEC HDT(HDT-301). Participants will be enrolled sequentially in three dose cohorts (cohort 1 = 1 µg, cohort 2 = 5 µg, and cohort 3 = 25 µg), with each cohort consisting of a total of 30 subjects. Within each dose cohort, participants will be randomized (4:1 ratio for active vaccine:placebo) with equal probability of receiving a schedule of two doses, of the same concentration, on days 1 and 28 (group 1) or 1 and 56 (group 2), or a schedule of single dose administration (group 3) VACCINE RNA MCTI CIMATEC HDT(HDT-301). The main objective is to evaluate the safety and reactogenicity of 3 dose vaccination schedule of VACCINE RNA MCTI CIMATEC HDT(HDT-301) and 1 dose of placebo in healthy adults. Safety and tolerability will be the primary endpoint assessed by incidence of adverse events for each dose through 12 months after the vaccination. Scheduled interim immunogenicity evaluations will be conducted for pre-specified timepoints as secundary and exploratory endpoints.
Saliva sampling could serve as an alternative non-invasive sample for SARS-CoV-2 diagnosis while rapid antigen testing (RAT) might help to mitigate the shortage of reagents sporadically encountered with RT-PCR. Thus, in the RESTART study the investigators compare antigen and RT-PCR testing methods on nasopharyngeal (NP) swabs and salivary samples. The investigators conducted a prospective observational study among COVID-19 hospitalized patients between 10th December 2020 and 1st February 2021. Paired saliva and NP samples were investigated by RT-PCR (Cobas 6800, Roche-Switzerland) and by two rapid antigen tests: One Step Immunoassay Exdia® COVID-19 Ag (Precision Biosensor, Korea) and Standard Q® COVID-19 Rapid Antigen Test (Roche-Switzerland).
