10 Clinical Trials for Various Conditions
BioFire Diagnostics, LLC (BioFire) has developed the FilmArray Gastrointestinal (GI) Panel, a rapid, easy to use PCR-based in vitro diagnostic test for the identification of 22 common microorganisms responsible for infectious gastroenteritis (http://filmarray.com/the-panels/) from a stool specimen collected in Cary Blair enteric transport media. The test was made available for sale in the US and EU following FDA clearance and CE marking in May, 2014. The FilmArray GI Panel offers improvements over conventional laboratory testing which include: reduced turnaround time from specimen to result, reduced laboratory labor costs, increased sensitivity and specificity relative to current clinical reference methods, and larger breadth of organism identification than is available using standard methods. Because of these attributes, the results from this test have the potential to enable clinicians to more accurately diagnose and treat GI illness in a reduced time frame. Collaborators at the University of Utah, Brown University/Lifespan, and BioFire Diagnostics have designed a study to evaluate health outcomes of pediatric subjects presenting to emergency departments with GI illness before and after establishing the FilmArray GI Panel as the standard of care method for stool pathogen analysis. It is hypothesized that the rapid (\~ 1 hour turnaround time), sensitive, specific, and comprehensive results provided by the FilmArray GI Panel will allow clinicians to more rapidly diagnose GI illness, initiate appropriate therapy and provide guidance when compared to the pre-implementation period.
The purpose of this study was to evaluate the efficacy of the Norwalk virus-like particle (VLP) vaccine as determined by the illness rate of viral acute gastroenteritis (AGE) during the inpatient stay.
This study is to determine the safety and immunogenicity of an Enterotoxigenic Escherichia coli (ETEC) candidate vaccine, attenuated recombinant Double Mutant Heat-Labile Toxin (dmLT) from ETEC, administered by the Intradermal (ID) route. The sample size has been determined based on the historic sample, not on power calculations.The study will involve 99 subjects (83 vaccinees and 16 placebo controls) in 4 consecutive cohorts of 16 individuals each (13 vaccinees and 3 placebo controls) and the final cohort of 35 (31 vaccinees and 4 placebos) subjects. The primary objective is to assess the safety and tolerability of dmLT vaccine when administered in three doses intradermally over a range of dosages in healthy adult subjects.
The ARIES C. difficile Assay is a real-time PCR based qualitative in vitro diagnostic test for the direct detection of C. difficile nucleic acid in stool specimens.
A Phase 1 dose escalating study of ETEC candidate vaccine to determine safety and immunogenicity of a multi-dose regimen in healthy adult volunteers. The study will be conducted at Cincinnati Children's Hospital Medical Center (CCHMC). The primary objectives assess the safety and tolerability of dmLT vaccine when administered in three doses sublingually over a range of dosages in healthy adult subjects. The secondary objectives assess long-term safety follow-up from immunization through Month 7 post vaccination, following three SL doses of dmLT vaccine over a range of dosages and comparing with three doses of a comparable dosage of oral vaccine. The study subject population is 52 healthy adult male and female subjects, ages 18 to 45. Subject participation duration is approximately 8 months with study duration of approximately 1.5-2 years, including 6-7 months of follow-up.
The xTAG Gastrointestinal Pathogen Panel (xTAG GPP) is a PCR-based assay to detect the presence or absence of gastrointestinal (GI) pathogens from human stool specimens. The objective of this study is to establish diagnostic accuracy of the xTAG GPP.
Rotavirus, sometimes called the "stomach flu," is the most common cause of severe diarrhea in children. Vaccines can prevent many types of infections and work by causing the body to make proteins called antibodies that fight infection. For some vaccines, more than one vaccination is needed so that the body will make enough antibodies to fight infection. The vaccines (RotaTeq® or Rotarix® oral vaccines) given in this study are recommended for infants by the Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP). These vaccines require either 2 or 3 vaccinations to be effective. Healthy infants between 6 weeks and 14 weeks, 6 days of age at Visit 1 will participate for about 10-12 months. Study procedures include reaction assessment and blood sample.
The goal of this research is to continue to develop a model of infection with Campylobacter jejuni, a bacterium that causes food and water-borne disease (mainly diarrhea). The objectives are to 1) determine if healthy subjects develop short-term (\<6 month) protection to reinfection with C. jejuni; and 2) characterize the immune responses to C. jejuni infection. Information obtained will be used in development of a vaccine against Campylobacter infections. Volunteers will be screened for eligibility within 60 days prior to enrollment. Screening will include obtaining informed consent prior to any study procedure. This will be followed by medical history, physical examination, review of current medications, blood samples for safety labs (WBC, Hct, Hgb, platelet count; chemistry panel; screening for HIV, HLA-B27, HBV, and HCV); urine pregnancy testing for females. Stool will be tested for infection. Eligible volunteers will be enrolled in the study and admitted to the GCRC on Day -1. They will drink a measured dose of C. jejuni on Day 0, and followed for approximately 9 inpatient days, during which time the investigators expect at least 75% to develop a diarrheal illness, which will be promptly treated with replacement fluids (oral or IV, as indicated) and antibiotics. During the inpatient period, subjects will be assessed for any adverse events, and blood and stool specimens will be analyzed for markers of infection and markers of immune response. Subjects must have resolved or resolving symptoms and two negative stool cultures ≥12 hours apart to be eligible for discharge, and will be seen in outpatient follow-up at 21, 28, 35, 60, and 90 days for additional AE assessments and blood and stool analysis. Eight subjects will return for redosing approximately 98 days after the initial dose, with the same inpatient and outpatient follow-up as above. Few or none should develop a diarrheal illness. Four naïve (previously unexposed) subjects will also receive the dose on Day 98 to confirm a 75% illness rate with this dose. They will be followed as the initial group was. All participants will be assessed by phone 6 months after the final dose they received.
Compare the effectiveness of automatic vs as-needed (PRN) post-hospitalization follow-up for children who are hospitalized for common infections.
We hypothesize the herbal preparation will enhance the preschoolers' immune response and when taken prophylactically for 12 weeks will decrease episodes of upper respiratory infections and gastroenteritis in the active versus the control group.
