Sanofi SA has announced an agreement to acquire Vigil Neuroscience, Inc., a clinical-stage biotechnology company specializing in therapies for neurodegenerative diseases. This acquisition will bolster Sanofi's neurology pipeline by introducing VG-3927, an investigational medicine aimed at treating Alzheimer's disease. The transaction is valued at approximately $470 million, with Vigil's shareholders receiving $8 per share in cash and a contingent value right for an additional $2 per share, dependent on the first commercial sale of VG-3927. The deal is expected to close in the third quarter of 2025, aligning with Sanofi's strategic focus on innovation in critical healthcare areas. Notably, VGL101, another molecule program from Vigil, will not be part of this acquisition.
