Novartis Acquires UK Biotech Myricx Bio to Enhance ADC Innovation

Novartis announced that it has entered into an agreement to acquire Myricx Bio, a privately held UK-based biotechnology company developing a new class of antibody-drug conjugates (ADCs), using N-myristoyltransferase inhibitor (NMTi) payloads.

The proposed acquisition would strengthen the Novartis oncology pipeline and advance next-generation targeted drug conjugates with novel payload mechanisms. Myricx’s approach is designed to deliver a differentiated cancer-killing payload directly to tumor cells, with the potential to address limitations of commonly used ADC payload classes such as TOPO-1 inhibitors. Myricx is developing two lead assets directed towards the targets B7-H3 and HER2, with potential across multiple solid tumor settings.

“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. “Myricx Bio has developed a promising NMTi payload platform with a differentiated mechanism that could broaden the use of ADCs across multiple tumor settings. This proposed acquisition reflects our strategy to scale innovative platforms, as we have with radioligand therapies, to deliver more durable, transformative treatments for patients.”
