Filter by:The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose lung cancer by comparing with clinical standard method (includes chest CT examination or pathological examination).
This randomized, double-blinded, placebo-controlled Phase 3 study is designed to evaluate the efficacy and safety of maternal immunization with RSVpreF against medically attended lower respiratory tract illness (MA-LRTI) in infants.
This phase 2b study will evaluate safety, tolerability, and immunogenicity of an RSV vaccine when given together with Tdap in approximately 710 healthy nonpregnant women 18 through 49 years of age. This study will evaluate non-inferiority of RSV vaccine when given with Tdap and vice-versa.
This Phase 2b study will evaluate the safety, tolerability, and immunogenicity of an RSV vaccine in pregnant participants who receive either one of 2 dose levels of the vaccine, formulated with or without aluminum hydroxide, or placebo, and investigate safety and characteristics of antibodies in their infants.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and incidence of anti-drug antibodies (ADAs) of single ascending doses of clesrovimab in healthy pre-term (born at 29 to 35 weeks gestational age) and full-term (born at >35 weeks gestational age) infants. Participants will be randomized into 1 of 4 dose escalation panels (Panels A to D); an additional panel (Panel E) of full-term infants will receive the same dose as Panel D. Key safety and tolerability variables will be reviewed after each dose panel prior to administering the next-highest dose.
The purpose of this study is to determine whether the consumption of a nutritional supplement with micronutrients and herbal extracts has an effect on the incidence of acute respiratory infections in susceptible adults. Our hypothesis is that subjects who consume the nutritional supplement will have a lower incidence and duration of acute respiratory infections in comparison with the placebo group.
This clinical study will investigate the relationships between sequential respiratory viral infections, patterns of intestinal and respiratory bacterial colonization, and adaptive cellular immune phenotypes which are associated with increased susceptibility to respiratory infections and long term respiratory morbidity in preterm and full term infants. This is a prospective, cohort study, enrolling at a single center via two sites (URMC and URMC-affiliated Highland Hospital and Rochester General Hospital). Enrollment will be accomplished in approximately 15 - 36 months. The study will enroll 280 subjects, 150 pre-term and 130 full-term.
xTAG RPP assay is a PCR-based assay to detect the presence or absence of viral and bacterial DNA / RNA in clinical specimens (nasopharyngeal swabs). The objective of this study is to establish diagnostic accuracy of the xTAG RPP.
This is a feasibility double-blind randomised controlled trial in 32 participants. It evaluates the feasibility of a full trial which will examine the efficacy of weekly supplementation of cholecalciferol (vitamin D3) relative to placebo on the subsequent frequency and severity of objectively-verified symptomatic acute respiratory tract infection, overall and as a proportion of detected colonisations of the upper respiratory tract by 9 of the most common aetiologic viral pathogens.
This study evaluates labeling comprehension, ease of use and effectiveness of a new device for nasal and sinus irrigation and/or aspiration. The device is currently cleared for professional use and home use with a prescription. This is a usability study to demonstrate that this device is appropriate for home use.
