AstraZeneca drug doubles survival in gastric cancer
AstraZeneca's experimental stomach cancer drug, sonesitatug vedotin, extended survival by five months compared to standard treatments, according to a study presented at the European Society for Medical Oncology meeting. The drug showed greater benefits when administered after two prior treatments. AstraZeneca estimates potential annual sales of $3B-$5B, with analysts suggesting up to $2.2B if the survival benefit is confirmed. The company is discussing the data with health authorities.
