20,000 cancer patients to get genetic profiling in hunt for new treatments
NCT ID NCT04932525
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will collect blood and tumor samples from 20,000 adults with solid tumors to perform detailed genetic analysis. The goal is to find how many patients have at least one genetic change that could be targeted by existing or experimental therapies. This is a research study, not a treatment, and aims to improve future cancer care by identifying more personalized treatment options.
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 help identify more genetic targets for cancer treatments, potentially leading to personalized therapies for many patients.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly benefit participants, and finding a targetable alteration does not guarantee an effective therapy exists.
