Summary

This Phase 2 study tests a new drug, telisotuzumab adizutecan (ABBV-400), combined with standard chemotherapy and an immunotherapy drug for people with advanced stomach, gastroesophageal junction, or esophageal cancer that cannot be removed by surgery. About 180 adults will receive either the new combo or standard treatment to see which works better at slowing cancer growth. The study will also find the best dose of the new drug.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Telisotuzumab adizutecan (ABBV-400) combined with budigalimab, fluorouracil, and leucovorin
What this could lead to
If successful, this could offer a new first-line treatment option for people with advanced stomach or esophageal cancer, potentially improving how long they live without their cancer growing.
What could go wrong
This is an early Phase 2 trial with only 180 participants, so results may not apply to everyone. The new drug combination may cause side effects or not work better than current treatments.
