Description

Project Summary Objectives The long term objective of this application is to develop novel products for routine point of care POC genetic testing ranging from pathogen identification to early cancer detection by using an innovative biotechnology called Isothermal Chain Reaction ICR ICR is a disruptive and enabling technology platform that will offer a new class of reagents relevant to biomedical research and medical healthcare ICR does not require any enzymes primers nucleotides master mixes extension reactions cDNA intermediates or thermocycling These benefits overcome constraints of PCR based technologies by being resistant to enzyme inhibitors found in laboratory samples and clinical specimens having higher specificity for rare mutations and lowering reagent costs ICR is anticipated to enable selective rapid and affordable biomarker detection without having to invest in costly instruments and labor intensive sample preparation procedures The envisioned products will be assays panels and kits for the early detection of infectious and genetic diseases in non laboratory settings Specific Aims Development of ICR probes to sepsis target sequences We will design and develop ICR assays to rapidly and isothermally detect synthetic target sequences associated with sepsis in a mixed population of templates in less than minutes under isothermal conditions without enzymes primers nucleotides or master mixes Identification of known sepsis pathogens in blood samples We will use ICR assays from Specific Aim to identify known sepsis pathogens from retrospective blood samples ICR results will be benchmarked to blood cultures to demonstrate the feasibility of using ICR for rapid early detection of sepsis biomarkers Identification of unknown sepsis pathogens in blood samples We will use ICR assays from Specific Aim to identify unknown sepsis pathogens from retrospective blood samples ICR results will be benchmarked to blood cultures to demonstrate the feasibility that ICR has enhanced selectivity to detect pathogens missed by blood culture methods and ICR is more amenable to point of care sepsis testing Impact Accomplishing the Specific Aims could significantly impact rapid and early detection of sepsis pathogens when therapeutic interventions are much more effective and enable routine clinical testing and screening of the disease to improve clinical triage decisions routine monitoring and treatment outcomes Project Narrative The relevance of this project is to demonstrate the feasibility of rapid and early identification of sepsis pathogens using a novel isothermal nucleic acid amplification technology The methods assays panels and reagents used in this project relate to enabling routine early sepsis screening and stratification in point of care settings in a rapid selective cost effective and easy to use manner under isothermal conditions
