Lyme disease: a problem seeking a diagnosis
  • Lyme disease is the fastest growing vector-borne disease in the US according to the CDC. 

  • It is often erroneously considered a regional disease limited to the Mid-Atlantic, Northeastern, and Upper Midwestern regions of the US 

  • Cases have been found in all 50 states

  • It is rapidly spreading into the Southeastern US, the mountain Western states, and into California making it a national problem.

  • Lyme disease is easily treated IF DETECTED WITHIN 10 WEEKS OF EXPOSURE

  • The lack of effective diagnosis Is the largest hurdle to addressing the Lyme disease epidemic

Poor current testing methods
  • ​The current CDC recommended Lyme disease diagnostic test is only 50% effective when treatment is effective.

  • The CDC assay detects antibodies developed after exposure to Lyme disease, or the body’s response to infection, and not the infection itself. 

  • This approach has significant issues

    • Slow production of antibodies results in a high false-negative rates (up to 60%) 

    • It is impossible to differentiate recent exposure for past exposure

      • Once antibody levels reach detectable levels, it remains high for up to a decade

  • CDC test is ineffective in:

    •  patients who are tested < 30 days following infection, 

    • those who have weak or suppressed immune responses. 

  • Identification of an active infection soon after exposure is critical

    • treatment is most effective with 6 weeks of exposure

Ionica's solution: IonLyme
  • IonLyme improves Lyme disease testing in two ways:

    • Detection within the time that treatment is effective

    • Allows differentiation between new and old exposures

  • IonLyme™ directly detects a protein, called Outer Surface Protein A (OspA) present only during active Lyme disease infections. 

  • OspA is found only when an active Lyme case is present. 

  • This change in testing paradigm provides capabilities not currently available to the clinician:

    • Provide accurate detection of Lyme disease within the effective treatment window

    • follow the efficacy of treatment 

    • determine if a patient has been re-infected

IonLyme: How it works
  • The IonLyme assay uses two well established technologies, aptamers​ & Surface Enhanced Raman Scattering (SERS)​, in a cutting edge method.

  • This combination produces a test capable of rapidly and specifically detecting OspA in serum samples obtained from human Lyme disease patients.
