Webinar Description:
This webinar describes how the RareCyte platform for CTC analysis was validated in the Clinical Diagnostics Lab (CAP accredited CLIA Lab) at Eli Lilly. Validation studies including analysis of accuracy and precision of CTC enumeration will be presented. As these results met the requirements of the Clinical Drug Study Team, the team at Lilly added the RareCyte platform to a global clinical trial for further evaluation in collaboration with a CRO.

A short presentation on RareCyte CTC assays for enumeration, multi-biomarker analysis, and custom assay development capabilities will follow.

Learning Objectives:

  • Learn why Eli Lilly is interested in CTCs and how they implement CTC analysis in clinical trials
  • Learn what attributes of a CTC platform are important
  • Learn how Eli Lilly analytically validated the RareCyte platform for CTC analysis in a CAP/CLIA laboratory
  • Learn about validated CTC assays from RareCyte and options to create custom assays
