NCT ID NCT04704661
First seen Nov 01, 2025 · Last updated May 06, 2026 · Updated 28 times
Summary
This early-phase trial tests a combination of two drugs—trastuzumab deruxtecan (a targeted chemotherapy) and ceralasertib (a cell-growth blocker)—in people with advanced solid tumors that have a HER2 mutation. The study first finds the safest dose, then compares the combo against the single drug in colorectal and gastroesophageal cancers. About 51 adults with various advanced HER2-positive cancers are participating.
