AstraZeneca PLCPositive Phase III data for sonesitatug vedotin in gastric cancer improves survival.

AstraZeneca reported positive Phase III results for sonesitatug vedotin in Claudin 18.2-positive advanced gastric cancer, showing an improvement in overall survival, while also sharing mixed data for Ultomiris in post-stem cell transplant thrombotic microangiopathy, with benefit in paediatric patients but the adult trial not meeting its primary endpoint. The stock trades around £129.4, up 18.0% over the past year and 73.3% over five years, though down 9.6% over the past month. The strong gastric cancer outcome and more mixed Ultomiris signal may influence how investors weigh future trial updates and regulatory milestones across the oncology and rare disease portfolios.
