Filter by:The aims of this prospective multicentric study is to determine the types of enteroviruses (EVs) responsible for hand, foot and mouth disease (HFMD) or herpangina in children seen within an ambulatory setting : - to detect an EV-A71 epidemic or another type associated with atypical forms of the disease at an early stage - to describe and compare the epidemiological, demographic, clinical and virological characteristics of these infections between the different types of EV.
Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
This study is a randomized, blinded study to evaluate the lot-to-lot consistency of immunogenicity, safety, and immune persistence of three consecutive manufacturing lots of EV71 vaccine, in 1500 children aged 6-35 months. The primary immunogenicity endpoint is the anti-EV71 neutralizing antibody geometric mean titer (GMT) 30 days after the final dose. The secondary immunogenicity endpoints are the geometric mean fold increases and seroconversion rates of anti-EV71 neutralizing antibodies 30 days after the final dose. The immune persistence endpoints are the seropositive rates as well as GMT of anti-EV71 neutralizing antibodies 12 and 24 months after the final dose. The safety endpoints are the number of adverse events/reactions within 30 minutes after each dose, the number of solicited adverse events/reactions within 7 days after each dose, the number of unsolicited adverse events/reactions within 30 days after each dose, and the number of serious adverse events (SAE) from the first dose to 6 months post the final dose.
The Phase I clinical trial is divided into two parts. The first part uses an open-label design, while the second part uses a randomized, double-blind, and controlled design. The goal of this clinical trial is to evaluate the tolerability and safety of a bivalent (EV71/CA16, Enterovirus 71/Coxsackievirus A16) inactivated enterovirus vaccine (Vero cell) developed by Sinovac. The vaccine will be administered to healthy adults, children aged 6 to 12 years, and children aged 6 to 71 months. The Phase II clinical trial will also use a randomized, double-blind, and controlled design to evaluate the safety and immunogenicity of the same bivalent inactivated enterovirus vaccine (Vero cell) developed by Sinovac. This trial will involve healthy children aged 6 to 71 months.
The objectives of this study are to evaluate the EV71vaccine efficacy, immune response and safety profiles after two injections of the cell culture-based inactivated EV71 vaccine with adjuvant Al(OH)3 administrated in pediatric population aged 2 months to 6 years old.
The purpose of the trial is to evaluate CUR-N399, a PI4KB inhibitor, in a first-in-human trial to evaluate the safety, tolerability and pharmacokinetics profile of single and multiple ascending doses in healthy adults. In the SAD part of the trial, single oral doses of CUR-N399 will be administered in 5 sequential cohorts. In all cohorts, safety and PK will be assessed before and after dose. Exploratory nasopharyngeal swab for assessment of airway infectants will be performed before dose and in the morning of Day 3. In SAD part Cohort 4: A urine sample will be taken from the first morning void on Day 1 and urine will be collected for potential quantification of CUR-N399 (and metabolites) during the first 24 hours post-dose. The MAD part of the trial will explore multiple ascending dosing of CUR-N399. The initial dose, dose escalation and dosing schedule will be based on emerging knowledge of safety, tolerability and PK of CUR-N399 observed in the SAD part of the trial. CUR-N399 will be administered in 3 sequential cohorts. An additional MAD cohort will evaluate CUR-N399 in older adults ≥65 years. All SAD and MAD cohorts will evaluate 8 subjects. Within each cohort, subjects will be randomised in a 3:1 ratio to receive CUR-N399 (n=6) or placebo (n=2) in a blinded fashion.
A randomized, double-blind, placebo-controlled study in 96 children and adolescents age 6-15 newly diagnosed with type 1 diabetes to describe the influence of antiviral treatment (Pleconaril and Ribavirin) on progression of disease and residual insulin secretion.
Beyond EV-B, there are clinical observations to implicate other viruses in birth defects, including CHD. Since the Rubella epidemic of 1960s', however, viruses have received little attention and certainly no comprehensive study, especially using next generation sequencing (NGS), has been undertaken in this context. The current pandemic as well as those caused by Zika, influenza, Ebola and Lassa Fever (among many) have shown pregnant women and their baby are at high risk. Therefore, an open-minded approach is warranted when considering the role of maternal viral infections in CHD. Even less is known about maternal immune response, such as antibody production, to these viruses. The investigator's goal is to answer the above gaps in knowledge. The investigators propose to do that using two different approaches; one retrospective (analysis of samples in two existing, large biorepositories) and the other prospective. The investigator's have created a multi-disciplinary team to bring together the needed expertise from individuals who have overlapping and vested interest in this project. The investigator's specific aim is to examine the diversity of the gut virome in non-pregnant and pregnant women with and without diabetes, with special emphasis on known cardiotropic viruses (those with tropism for cardiac tissues). This study is seen by the investigator's as the first step prior to a larger prospective multi-institutional study to specifically assess the linkage between the maternal virome and CHD pathogenesis.
Enteroviruses (EV) are the most frequent cause of acute meningitis in the paediatric population. Detection of enterovirus in cerebrospinal fluid (CSF) specimens by Polymerase Chain Reaction (PCR) is the gold standard diagnostic test. Recently, our laboratory published the BLEDI study which highlighted the interest of detecting EV in the blood of the paediatric population : (i) EV was found in more than a quarter of cases in the blood of infants admitted to hospital with isolated fever and (ii) detection of EV was more frequent in the blood than in CSF in neonates and infants with isolated fever, sepsis or meningitis. However, the pathophysiology of EV infections is poorly understood and little work has been done on the inflammatory response to these infections. In EV meningitis, the inflammatory response has been studied primarily in children infected with enterovirus A71 (EV-A71). Indeed, in these children, inappropriate cytokine secretion (cytokine storm) leads to severe neurological and cardiopulmonary damage, which can progress to death. The study of the inflammatory response during meningitis due to other types of EV remains poorly The objective of BLEDI-CYTOKINES (ancillary study of the BLEDI study) is to study the inflammatory response during EV meningitis in neonates, infants and children, as assessed by cytokine levels in blood and cerebrospinal fluid, by comparing case-controls from an existing cohort.
CRISPR-enterovirus detection system was constructed in this study for detection variety genotypes of enterovirus rapidly in children suspected or diagnosed as enterovirus infection.
