Joanne Xiu: Real-world evidence provides clinical insights into tissue-agnostic therapeutic approvals

“In light of the increase in Tissue-Agnostic approvals by the FDA for cancer therapy, an extensive analysis of a vast real-world database at Caris Life Sciences reveals important clinical insights and highlights the transformative power of real-world data.

The research uncovered the potential to expand Tissue-agnostic approval for drugs of the same class, and unveiled important variation among tumor types for existing approvals; all these insights were made possible only through the extensive real-world dataset.”

Matthew Oberley, Chief Clinical Officer and Senior Vice President at Caris Life Sciences, shared this post on LinkedIn, adding:

“A concerning finding from this excellent study utilizing RWE from Caris Life Sciences and ConcertAI: Less than half of patients with pathogenic NTRK fusions get highly efficacious targeted therapy with NTRK inhibitors – I am concerned that Oncologists are not always seeing the results from molecular profiling before choosing a therapeutic pathway for their patients.

This observation supports findings of NTRKi underutilization noted previously in a survey of US oncologists.”
