Blood samples may unlock secrets of cancer drug resistance

NCT ID NCT05272423

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study collects blood samples from up to 500 adults in the US with KRAS G12C-positive cancer whose disease has progressed after treatment with a KRAS inhibitor. Researchers will analyze the samples to identify genetic changes that cause resistance. The goal is to compare resistance patterns between different drugs and cancer types, which may guide future treatment strategies.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this could reveal why some cancers become resistant to KRAS inhibitors, pointing toward better combination treatments.

What could go wrong

This is an observational study, not a treatment trial. It collects data only, so it won't directly help participants. Results may not lead to new therapies quickly.
