An observational study in Respiratory Tract Infections and Gastrointestinal Infection, sponsored by BioFire Diagnostics, LLC. Status unknown at 1 site in United States. Per ClinicalTrials.gov, last updated 2019-01-15.
Sponsored by BioFire Diagnostics, LLC · Observational
The purpose of this study is two-fold. In the first phase, the goal is to characterize the stability of respiratory (nasal swab, nasopharyngeal swab, and throat swab; NS, NPS, TS) and stool (raw stool and rectal swab) specimens collected using various standard, medically established procedures with and without transport media and tested at various time points and under different temperature conditions, and also to look at variation between repeat sampling events. The intention is for these data to support decisions made by BioFire regarding the appropriate specimen type and handling guidelines for future tests. In the second phase of the study, collection and transport conditions identified in Phase 1 will be used to collect specimens for pilot performance evaluations of a new molecular diagnostic test.
This evaluation will be initiated at several sites in the US. In the first phase of the study, multiple specimens will be collected from each subject and tested using various pre-analytical techniques. Current BioFire FilmArray test panels will be used to assay each specimen and evaluate the multiple variables: repeat sampling, native specimen stability, or other post-collection variables. In the second phase of the study only two specimens will be collected from each subject: one for testing with the new test (using handling procedures identified in Phase 1) and another for testing with the reference method. Up to 2,000 subjects will be enrolled across all sites in each phase (up to 4,000 subjects total). Enrollment is expected to last approximately 18 months to cover both phases of the study. All specimens and subject data will be de-identified and coded. Prior to study initiation, each participating site will have the necessary Institutional Review Board (IRB) reviews. Specimens in both phases will be tested at the study site using various BioFire test platforms and cartridges.
751 studies on the registry are indexed under Respiratory Tract Infections; 114 are open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Subject presents with signs/symptoms of respiratory infection including but not limited to fever, cough, sore throat (pharyngitis), runny nose, myalgia, headache, chills, or fatigue
Diagnostic Test: BioFire test platform
Subject presents with suspected gastroenteritis (e.g. diarrhea, vomiting, nausea, etc.) with duration of symptoms less than or equal to 7 days
Diagnostic Test: BioFire test platform
Analysis of analyte stability under various conditions as measured by BioFire test platforms
Analyte stability (as measured by nucleic acid detection)
Sensitivity (or positive percent agreement) and specificity (or negative percent agreement) of the assays comprising the FilmArray Panel with respect to reference methods will investigate analyte stability for the various pre-analytical steps. Analyte stability will be measured by assessing nucleic acid level using real-time PCR.
Time frame: Through completion of Phase 1 (approximartely 9 months)
Device performance relative to reference methods
Sensitivity (or positive percent agreement) and specificity (or negative percent agreement) of the assays comprising the FilmArray Panel with respect to reference methods will determine device performance relative to reference method(s) i.e. if an anlyte is detected (or not) by each method (presence or absence)
Time frame: Through completion of Phase 2 (approximately 9 months)
Plan to share: No

Started Oct 2017 (actual). Primary completion is estimated for Oct 2019, 24 months after the start.
Of 85 observational studies under Respiratory Tract Infections, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 42. This study's planned 24 months is above that.
