Experimental cancer drug trial halted early
NCT ID NCT04982926
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tested a new drug called TAS2940 in 29 people with advanced solid tumors (like lung, breast, or brain cancer) that had specific genetic changes (EGFR or HER2). The goal was to find a safe dose and see if the drug could shrink tumors. The study was stopped early, so results are limited.
