Sanofi, based in Paris, has invested $40 million in Vigil Neuroscience through the purchase of 537,634 Series A non-voting preferred shares at $7.44 per share. Each of these shares can be converted into 10 common shares of Vigil's stock. The investment will primarily fund the clinical development of multiple agents within Vigil's pipeline, focusing notably on an Alzheimer's drug targeted at a genetically defined population.
Vigil's flagship candidate, VG-3927, operates within its small molecule TREM2 agonist program, aiming to address dysfunctional microglia—a critical type of immune cell in the central nervous system. The drug is currently undergoing Phase I clinical trials among healthy adults. Research indicates that normally functioning microglia play a role in reducing beta-amyloid plaque levels in the brain, while a functional TREM2 is essential in preventing tau protein aggregates linked to Alzheimer's disease.
Sanofi's investment not only supports Vigil's immediate financial needs but also grants Sanofi the exclusive right to negotiate the licensing of agents from Vigil's TREM2 agonist program. Erik Wallstroem, Sanofi's global head of neurology development, emphasized the significance of microglial signaling and neuroinflammation in neurodegenerative diseases, underlining Sanofi's deepened commitment to immunoscience and neuroimmunology through this partnership.
Headquartered in Watertown, Massachusetts, Vigil anticipates that the infusion of funds will extend its financial runway through 2026. This strategic collaboration marks a significant step forward in advancing therapies targeting Alzheimer's and related conditions by leveraging insights into the role of microglia and TREM2 signaling pathways in neurodegenerative processes.
