About this study

Researchers are testing a treatment with ceralasertib (AZD6738) and trastuzumab deruxtecan in people with advanced solid tumors that have HER2 changes or protein. The goal is to find the best dose of this combination for safety, side effects, and effectiveness. The trial also compares how colorectal and gastroesophageal cancers respond to treatment with ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone.

Based on ClinicalTrials.gov records.
