Trials that select patients by Claudin 18.2 expression, the therapies approved for it, and who is developing what. Seen most often in gastric/GEJ, pancreatic.

Added in v3.0. Matches on this page are included in our accuracy checks (about 9 in 10 correct across all pages) but have had fewer checks than the original pages. Every trial shows the words that matched.

Approved therapies

Approvals in the United States (FDA) and the European Union (EMA), one row per drug, regimen and tumour type. Where we have them, the pivotal trial's results and side effects are shown under each therapy, from the official label. Results from different trials are not directly comparable: patients, earlier treatments and comparators differ.
