Sofinnova Partners Announces Myricx Bio Agrees to Be Acquired by Novartis
The deal includes $1.1 billion upfront and could expand Myricx Bio’s NMTi payload platform for antibody-drug conjugates, Novartis said.
On Monday, Novartis agreed to acquire UK-based oncology company Myricx Bio for up to $1.5 billion, including $1.1 billion in upfront cash plus potential milestone payments.
Myricx specializes in next-generation N-myristoyltransferase inhibitor payloads for antibody-drug conjugates , aiming to overcome toxicity and resistance limitations of earlier TOPO-1 and tubulin inhibitor classes.
Brandon Capital and Sofinnova Partners, both venture capital firms, backed Myricx from its 2019 founding at Imperial College London. The company raised $114 million in a Series A during mid-2024 under CEO Mohit Rawat.
Novartis plans to integrate Myricx's two lead ADC assets targeting B7-H3 and HER2 into its global oncology portfolio. Rawat said the combination will help "transform the landscape of cancer treatment" with more effective therapies.
The transaction is expected to close in the second half of 2026, subject to regulatory approvals. This marks Sofinnova's seventh exit in three years, demonstrating its model of backing early-stage European biotechnology.
