• Seagen has acquired ex-Asian rights to RemeGen's disitamab vedotin for $200 million upfront, with potential payments of $2.4 billion, targeting HER2-positive cancers including breast, bladder, and gastric tumors.
• The antibody-drug conjugate has already received conditional approval in China for HER2-positive gastric cancer and breakthrough designation from FDA for bladder cancer.
• The deal positions Seagen to compete with established HER2-targeting ADCs like AstraZeneca/Daiichi Sankyo's Enhertu and Roche's Kadcyla, while focusing initially on distinct market segments.
