AstraZeneca and AgPlus present clinical data at ERS 2017

AstraZeneca and AgPlus Diagnostics present clinical data from a novel, 10 minute, electrochemical point of care assay system for the measurement of Eosinophil Derived Neurotoxin (EDN) at ERS 2017

AgPlus and AstraZeneca have worked together to develop a novel point of care test (based on AgPlus’ patented electrochemical immunoassay platform technology) for EDN and have reported the results from a successful pilot clinical study at ERS 2017. A copy of the poster is now available here: ERS 2017 AgAZ poster.

Increased blood eosinophils (EOS) are associated with increased exacerbations, disease severity and mortality in asthma. EDN is an alternative biomarker of eosinophilia that may better reflect eosinophil activity than EOS. EDN can be measured by immunoassay but a clinical diagnostic is not available. In this study, a prototype point of care assay system for the detection of EDN was assessed using a 20ul sample of venous blood, capillary blood or plasma from 10 patients recruited on their historical eosinophil levels to represent a wide range.

The key conclusions of the study were:

  • EDN was measurable in capillary blood, venous blood and plasma with the novel point-of-care electrochemical immunoassay platform giving a result in under 10 minutes.
  • The measured EDN levels were highly correlated to blood eosinophils.
  • EDN may be an alternative biomarker of eosinophilic asthma to EOS and is amenable to rapid, point of care diagnostic technology and since EDN release is an active process that can be triggered by inflammatory mediators, EDN may reflect active pathology in eosinophilic asthma better than eosinophil counts.
