Summary

This trial is investigating the safety and preliminary effectiveness of a new cancer drug, trastuzumab deruxtecan (T-DXd), for treating HER2-positive gastric and esophageal cancers. The study will also look at whether T-DXd is more effective when given in combination with other cancer treatments.

Who is the study for?
This trial is for adults with advanced HER2-expressing stomach, GEJ, or esophageal cancer. Participants must have progressed after a trastuzumab regimen (Part 1) or be untreated for metastatic disease (Part 2), and have measurable disease. They need proper organ function and agree to contraception if of reproductive potential. Exclusions include active infections like HIV/HBV/HCV, uncontrolled illnesses, CNS metastases, lung issues like ILD/pneumonitis, and problematic fluid accumulation.
What is being tested?
DESTINY-Gastric03 tests the safety and effectiveness of T-DXd alone or combined with chemotherapy/immunotherapy in advanced gastric cancers expressing HER2. The study aims to find tolerable doses that show anti-tumor activity as a potential new treatment option for patients who haven't received prior therapy for their metastatic disease.
What are the potential side effects?
Potential side effects may include reactions related to immune system activation such as inflammation in various organs, infusion-related reactions from the drugs administered intravenously, fatigue due to treatment burden on the body's resources, digestive disturbances from chemotherapy agents affecting rapidly dividing cells including those lining the gut.
