Vicebio has entered an exclusive, definitive agreement to be acquired by Sanofi. Under the terms of the agreement, subject to customary conditions, Vicebio shareholders will receive up to a total of US$1.6 billion, including an upfront payment of US$1.15 billion as well as development and regulatory milestones payments of US$450 million.
Vicebio was created by Medicxi to develop next-generation vaccines for respiratory viruses utilizing its proprietary Molecular Clamp technology, discovered at The University of Queensland. This technology uniquely stabilizes viral glycoproteins to elicit strong protective immune responses and enables high-yield production for ready-to-use liquid multivalent formulations. The Molecular Clamp technology is applicable to a wide range of viruses including Respiratory Syncytial Virus (RSV), Human Metapneumovirus (hMPV), Parainfluenza viruses, Influenza and Coronaviruses. In September 2024 Vicebio announced a Series B financing, led by TCGX with investment from Life Sciences at Goldman Sachs Alternatives, Avoro Ventures, venBio Partners, and with participation from UniQuest and founding investor Medicxi, which enabled Vicebio to accelerate clinical development of VXB-241 and next generation products.
Vicebio is currently running an exploratory Phase 1 clinical trial with lead asset VXB-241, a bivalent vaccine targeting both RSV and hMPV viruses, pathogens that are a significant burden in the elderly and those with a weakened immune system. Interim analysis of the exploratory Phase 1 study showed a favorable safety and tolerability profile in adults aged 60 and above.
