WATERTOWN, Mass., June 27, 2024 (GLOBE NEWSWIRE) — Vigil Neuroscience, Inc. (Nasdaq: VIGL), a clinical-stage biotechnology company committed to harnessing the power of microglia for the treatment of neurodegenerative diseases, is pleased to announce that Sanofi (Nasdaq: SNY) has made a $40 million strategic investment in the Company at an as-converted price of $7.44 per share of common stock. Sanofi will purchase 537,634 of the Company’s Series A non-voting preferred shares, each share of which shall be convertible into ten shares of common stock. The Company will use the proceeds to fund its research and development activities.

“We are excited by this strategic investment from Sanofi, one of the world’s leading biopharmaceutical companies, for our research and development programs,” said Ivana Magovčević-Liebisch, Ph.D., J.D., President and Chief Executive Officer of Vigil. “We view Sanofi’s investment in Vigil as a validation of our promising precision medicine approach led by our two differentiated TREM2 modalities, iluzanebart and VG-3927, and Sanofi has provided valuable capital to help fund our pipeline. We look forward to the opportunity to work with Sanofi as we continue to advance our small molecule TREM2 agonist program.”

“Recent discoveries have highlighted the role of microglial signaling and neuroinflammation in neurodegenerative diseases. TREM2 is a well credentialed microglia target in this context,” said Erik Wallstroem, Sanofi’s Global Head of Neurology Development. “The investment in Vigil strengthens our commitment to immunoscience and neuroimmunology.”

In connection with the equity investment, Vigil has granted Sanofi the exclusive right of first negotiation (ROFN) for an exclusive license, grant or transfer of rights to research, develop, manufacture and commercialize the Company’s small molecule TREM2 agonist program, including its clinical candidate, VG-3927. VG-3927 is currently being evaluated in a phase 1 clinical study for the potential treatment of Alzheimer’s disease.

Based on current projections, the Company expects that the proceeds from Sanofi’s investment will extend its cash runway into 2026.
