How Amprion Helps Accelerate Drug Development

Amprion helps biopharma partners address the following challenging questions related to drug development in neurodegenerative diseases:

Patient Stratification & Early Identification

  • What underlying pathologies are in play?
  • Do patient genetics affect responses to each candidate?
  • Can patient genetics + PMCA effectively ID pre-clinical disease?
  • How do pre-dosing responses predict target engagement post-dosing?
  • Can PMCA inhibition pre-select patients most likely respond to each candidate?


Target Engagement

  • Measures binding/sequestration of CSF prion-like proteins by immunoprecipitation
  • How is binding affected by increasing concentrations of native protein?
  • What concentrations are required for 80% & 95% target engagement?
  • How do binding curves vary between different patients?
  • Do antibody combinations outperform single species?
  • How do monospecific versus bi-specific antibodies perform?


Direct Target Inhibition

  • Which candidates & structures can directly inhibit prion amplification?
  • How do IC50 levels correlate with CNS candidate concentrations?
  • How do various candidates modulate aggregation kinetics?
  • A single platform can evaluate antibodies, peptides, small molecules.


Disruption of Pre-formed Fibrils (Plaque/Tangle/Lewy Body)

  • Which candidate concentrations are most effective?
  • What is the disaggregation kinetics for each candidate?
  • Is it possible to shift the equilibrium towards more inactive fibrils?
  • Which candidates favor large fibrils versus smaller prion-like structures?
  • Which degradative enzymes impact fibril structures?

For the first time in history, we can track the misfolded proteins associated with brain diseases in the early stages. 

Please Note: Important Billing Info

To improve patient access to the SYNTap® Biomarker CSF Test, Amprion offers the following billing options:

  • List price of $1500, with courtesy billing for both Medicare and private insurance.
  • An affordable self-pay price of $995 (patients may qualify for financial assistance and/or interest-free payment options).
  • Prices are effective as of January 1, 2024, and are subject to change.

Please note: Amprion is a Medicare participating provider, however, the SYNTap test does not currently have Medicare coverage determination. Also, Amprion is not yet in network with most insurers.

The SYNTap Biomarker CSF Test has been issued a dedicated CPT® PLA code to be used when billing: 0393U.
