Recent FDA approval of MI Cancer Seek as the first simultaneous whole exome and whole transcriptome sequencing-based companion diagnostic strengthens Caris' regulatory position 7 8 18.

Regulatory Environment and Recent Approvals

FDA Approvals and Market Access

A significant quality of earnings positive development was the November 2024 FDA approval of MI Cancer Seek as a companion diagnostic test 7 8 18. This approval represents the first and only simultaneous whole exome and whole transcriptome sequencing-based assay with FDA-approved companion diagnostic indications for solid tumors 7 19. The test includes one pan-cancer and five tumor-specific indications for numerous FDA-approved therapies, available for both adult and pediatric patients (ages 1-22) 7 19.

This regulatory milestone provides several business benefits: enhanced reimbursement prospects, competitive differentiation, expanded market access, and validation of Caris' scientific approach 7 8. The companion diagnostic designation links specific biomarker results to FDA-approved therapies, potentially improving payer coverage and physician adoption 19 18.
