Filter by:The purpose of the study is to design and execute a prospective, longitudinal, descriptive cohort study in a pragmatic clinical practice for adults with symptoms that may be related to COVID-19.
This trial has two parts. Part A and Part B. Due to changes in the overall clinical development plan, Part B will no longer be conducted. The objectives originally described for Part B have been implemented in the ongoing development via a pivotal Phase I/II/III trial BNT162-02/C4591001 (ClinicalTrials.gov NCT: 04368728). Part A is for dose ranging of four different vaccines (BNT162a1, BNT162b1, BNT162b2, and BNT162c2) which will be undertaken with dose escalation and de-escalation plus the evaluation of interim dose levels. It also includes dose ranging in older participants. The vaccines BNT162a1, BNT162b1, BNT162b2, and BNT162c2 will be administered using a Prime/Boost (P/B) regimen. The vaccine BNT162c2 will also be administered using a Single dose (SD) regimen. Three additional cohorts aged from 18 to 85 years receiving BNT162b2 only. BNT162b2 has entered a Phase II/III evaluation of efficacy, with the intent to support an application for marketing authorization. The dosing regimen under investigation is two BNT162b2 doses given ~21 d apart.
The new Severe acute respiratory syndrome coronavirus (SARS-CoV-2) named coronavirus disease 2019 (COVID-19) is currently responsible for a pandemic spread of febrile respiratory infections, responsible for a veritable global health crisis. In adults, several evolutionary patterns are observed: i) a/pauci-symptomatic forms; ii) severe forms immediately linked to rare extensive viral pneumonia; and iii) forms of moderate severity, some of which progress to secondary aggravation (Day 7-Day 10). Children can be affected, but are more rarely symptomatic and severe pediatric forms are exceptional. Like some other coronaviruses (SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV)), these differences in clinical expression could be based on a variability in the immunological response, notably either via inhibition of the type I interferon (IFN-I) response, or on the contrary an immunological dysregulation responsible for a "cytokine storm" associated with the aggravation. Little is known about the impact of these innate immune response abnormalities on the adaptive response. In addition, certain genetic factors predisposing to a state of "hyper-fragility" and certain viral virulence factors could also be predictive of the clinical response. In this context, the main hypothesis is that the virological analysis and the initial biological and immunological profiles are correlated with the initial clinical presentation of COVID-19 infection. In particular, children forms and pauci-symptomatic disease in adults may be linked to a more robust innate immune response, including better production of IFN-I.
This is a prospective study, involving contacting potential plasma donors and the use of their plasma to help fight off infections of those suffering from COVID19 in accordance to collection guidelines for plasma and FDA IND requirement. This study will include up to 240 participants potentially receiving convalescent plasma and up to 1000 potential donors. There are 3 basic arms to the study: mild, moderate and severe/critical severity. All 3 severity groups are eligible for enrollment, but mild severity will not be given plasma unless there is progression. Moderate severity will given up to 1 unit of plasma and severe/critical severity up to 2 units. There is no placebo group, however given the excepted issues of shortages of plasma, intention to treat will be used for analysis.
This study aims to investigate the effect of probiotic added to the diet of mothers on infantile colic in the postpartum period and the content of the neonatal intestinal microbiota.
An Open-label, prospective, randomized, comparative, multiple doses applied in addition to the standard of care treatment of patients with moderate to severe COVID-19 infection
The objective of this application is to increase PrEP uptake among AA women at-risk for HIV-infection in the rural South, specifically those seeking care at Federally Qualified Healthcare Centers (FQHC) in rural Alabama. The investigators will use a mixed-methods approach to adapt and pilot test a patient-provider communication tool from the CDC PrEP toolkit that focuses on the first three steps of the PrEP cascade (e.g., recognizing HIV risk, identifying as a PrEP candidate, and interested in PrEP) to increase PrEP uptake via referrals to local PrEP clinics.
Mandibular osteitis after flap reconstruction is rare but is a serious infection with significant sequelae. The aim of this study is to describe this type of infection
COHIVE is an observational cohort nested in four antiretroviral therapy research studies (ADVANCE - NCT03122262; D²EFT - NCT03017872; DolPHIN2 - NCT03249181 and NAMSAL-ANRS12313 - NCT02777229). COHIVE will include participants who are possible COVID-19 cases with symptoms or confirmed COVID-19 cases, and participants who agree to have a serology testing for SARS-CoV-2 regardless of COVID-19 history.
Patient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective - To determine the clinical characteristics and outcomes of Covid-19 in children. - To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives - To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. - To evaluate the duration of SARS-CoV-2 viral shedding in children. Exploratory Objective
