Ironwood Pharmaceuticals Enters into Agreement to Acquire VectivBio

Monday, May 22, 2023

Ironwood Pharmaceuticals and VectivBio Holding announced that they have entered into a definitive agreement for Ironwood to acquire VectivBio for $17.00 per share in an all-cash transaction with an estimated aggregate consideration of approximately $1 billion, net of VectivBio cash and debt (the “Transaction”).

This agreement with Ironwood will advance the development and commercialisation of innovative therapies targeted at GI and rare diseases, which is the mission of VectivBio. 

The acquisition of VectivBio and its lead investigational asset apraglutide provides a significant opportunity to accelerate the next growth horizon for Ironwood. The Transaction has the potential to deliver meaningful strategic and financial benefits, including:

Strengthens and complements Ironwood’s portfolio. Ironwood has a blockbuster asset in LINZESS, a strong GI commercial function, and an exciting pipeline of development assets. Ironwood believes that this transaction will further strengthen its portfolio and pipeline, with the potential to meaningfully accelerate its growth horizon.

Leverages Ironwood’s existing infrastructure. Ironwood has strong expertise in clinical development, regulatory pathways, and medical affairs, as well as a robust commercial infrastructure. Additionally, Ironwood also has existing relationships within the gastroenterologist community, and a knowledgeable speciality salesforce that currently addresses a significant portion of apraglutide’s potential prescriber base. Ironwood intends to leverage its proven expertise from LINZESS’s successful commercialisation and ongoing lifecycle management to maximise the apraglutide opportunity.
