Question · Q3 2025
Simon Baker requested an update on confidence in Sonivodotin as the gastric phase III data approaches in H1 2026, and thoughts on the broader scope of Claudin 18 beyond gastric cancer.
Answer
EVP of Oncology R&D Susan Galbraith expressed encouragement for Sonivodotin, a Claudin 18.2 ADC, citing encouraging response rates in late-line patients and its potential in earlier-line settings and combinations with IO therapy. She noted Claudin 18.2's expression in over 50% of gastric cancer patients and its presence in pancreatic cancer, where AstraZeneca is also exploring its data.
