ZURICH, July 6 (Reuters) – Swiss drugmaker Novartis said on Monday ‌it had agreed to pay ‌up to $1.5 billion for U.K.-based biotechnology firm ​Myricx Bio in a deal expected to close in the second half of 2026.

In a statement, Novartis ‌said it ⁠would pay $1.1 billion upfront, alongside up to $400 million in ⁠potential milestone payments, to acquire London-based Myricx Bio, which develops ​antibody-drug conjugates ​used for ​treating cancer.

“ADCs have ‌become an important part of cancer treatment, but there remains a clear need for new payload mechanisms to overcome resistance and expand ‌their impact for patients,” ​said Fiona Marshall, ​president of ​biomedical research at Novartis.

“This ‌proposed acquisition reflects our ​strategy ​to scale innovative platforms, as we have with radioligand therapies, to ​deliver ‌more durable, transformative treatments for ​patients.”
