Shionogi Invests Over $600M in BioVersys' Antibiotic Program to Combat Antibiotic Resistance

Japanese pharmaceutical giant Shionogi has entered into a significant collaboration with Swiss biotech company BioVersys, investing more than $600 million in a preclinical antibiotic program. This strategic partnership aims to bolster the fight against antibiotic resistance, particularly focusing on nontuberculous mycobacterial (NTM) infections.

Deal Structure and Financial Details

Shionogi will make an upfront payment of 5 million Swiss francs ($6.3 million) to BioVersys for its BV500 program. The agreement includes potential regulatory and sales milestones totaling up to 479 million Swiss francs (approximately $604 million), as well as tiered royalties. This substantial investment underscores the pharmaceutical industry's commitment to addressing the growing concern of antibiotic resistance.

Scientific Focus: Ansamycin Antibiotics for NTM Infections

The collaboration centers on the development of ansamycin antibiotics, a class of compounds produced by Actinomycetes bacteria. These antibiotics work by disrupting RNA manufacturing within targeted bacterial cells. BioVersys' research teams in France and Switzerland have already developed multiple ansamycin compounds that have shown efficacy in killing NTMs.

NTM infections, primarily caused by Mycobacterium avium complex and Mycobacterium abscessus subspecies, affect approximately 250,000 people annually. These infections are particularly challenging to treat, often requiring years of therapy with multiple antibiotics. The most common NTM lung infections typically occur in patients with pre-existing lung conditions such as chronic obstructive pulmonary disease.

Strategic Implications and Industry Context

This collaboration represents a significant step in addressing unmet medical needs in infectious diseases. Dr. John Keller, Senior Vice President of Shionogi's R&D supervisory unit, emphasized the company's commitment to advancing innovative treatments in this field.

For BioVersys, the partnership offers an opportunity to reduce research and development risks while maintaining financial discipline. Dr. Marc Gitzinger, Co-founder and CEO of BioVersys, highlighted that the collaboration would expand the reach of their pipeline and ensure expedited development of their drug candidates.

The deal with BioVersys follows Shionogi's previous $100 million investment in F2G's antifungal olorofim in 2022, demonstrating the company's continued focus on combating infectious diseases. However, the F2G investment has yet to yield significant returns, with the FDA rejecting olorofim in 2023.

As antibiotic resistance continues to pose a global health threat, collaborations like this between large pharmaceutical companies and innovative biotechs may become increasingly crucial in developing new and effective treatments for resistant infections.
