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 study will evaluate the safety, tolerability, and immunogenicity of up to 7 different RSV vaccine candidates, some with adjuvant, when administered concomitantly with seasonal inactivated influenza vaccine (SIIV) and may evaluate a second dose of RSV vaccine administered12 months after the initial dose. In addition the study will evaluate a 2-dose regimen administered 2 months apart to 62 subjects.
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.
It is advocated that prolonged infusion of beta-lactamic antibiotics provides better bactericidal effect. The aim of the present study is to randomize patients a to extended cefepime infusion regimen (lasting four hours) or to a usual infusion regimen (not lasting more than thirty minutes) and evaluate the clinical efficacy of this theoretical pharmacokinetic advantage.
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.
The ARIES Flu Assay is a real-time PCR based qualitative assay for the direct detection and differentiation of respiratory viral nucleic acid in nasopharyngeal swabs specimens. The objective of this study is to establish the diagnostic accuracy of ARIES Flu Assay.
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.
