Germany-based Merck KGaA has concluded the acquisition of Mirus Bio for €500m ($600m), enhancing its viral vector bioprocessing capabilities.

The companies entered a definitive agreement in May 2024 under which Merck’s Life Science business in the US and Canada, MilliporeSigma, would acquire Mirus Bio.

The deal aligns with Merck’s strategy to offer comprehensive solutions across the entire viral vector manufacturing spectrum, from preclinical stages to commercial production.

Mirus Bio, previously part of Gamma Biosciences, focuses on the development and commercialisation of transfection re-agents, essential in the production of viral vector-based gene therapies.

The acquisition of Mirus Bio’s transfection re-agents, such as TransIT-VirusGEN, will enhance Merck’s upstream portfolio, enabling the company to offer an integrated approach to viral vector manufacturing.

The integration of Mirus Bio’s transfection technologies into Merck’s portfolio strengthens the company’s position in the viral vector manufacturing market.
