Sanofi has agreed to acquire Vigil Neuroscience in a $470 million deal, reinforcing its investment in Alzheimer’s disease and neuroinflammation. The acquisition includes VG-3927, a TREM2 agonist designed to restore microglial function and slow Alzheimer’s progression in its early stages.
The deal includes $8 per share upfront plus a $2 CVR tied to drug milestones. It builds on Sanofi’s earlier $40M equity stake and gives them exclusive rights to Vigil’s neuroinflammation pipeline, while excluding their prior VGL101 program, now returned to Amgen.
Spencer Knight notes this gives Sanofi a new foothold in Alzheimer’s innovation, placing them in competition with Denali, Biogen, and Eisai.
