NCT ID NCT04932525

First seen Feb 06, 2026 · Last updated May 16, 2026 · Updated 13 times

Summary

This study aims to analyze the DNA of tumors from 20,000 adults with cancer to identify genetic changes that can be targeted with existing or experimental drugs. By profiling each person's cancer, researchers hope to learn how many patients have a 'targetable' mutation and how often that information leads to a personalized treatment plan. Participants provide a tumor sample for advanced genetic testing, but the study itself does not provide any treatment.
