This acquisition in neurology, one of Sanofi’s four strategic disease areas, enhances Sanofi’s early-stage pipeline and includes VG-3927, which will be evaluated in a phase 2 clinical study in Alzheimer’s disease. 

Houman Ashrafian, Head of Research and Development, Sanofi commented: “This acquisition is fully supporting Sanofi’s strategic focus on neurology and on advancing science and leveraging our expertise in immunology to solve areas of critical unmet need. Vigil’s expertise is complementary to our capabilities in neurology and reinforces our dedication to developing innovative medicines to improve people’s lives. Vigil’s team are a welcome addition, and we look forward to working with them and the patient community.”

Ivana Magovčević-Liebisch, President & Chief Executive Officer, Vigil added: “We are incredibly proud of the extraordinary and diverse team at Vigil and the progress we have made in developing innovative TREM2-based therapeutics. We look forward to joining forces with Sanofi's team to leverage Sanofi’s resources, broad platform and far-reaching network to fully unlock and accelerate the development of VG-3927 for the potential treatment of Alzheimer’s disease – a devastating disease with significant unmet need.”

In June 2024, Sanofi made a $40 million strategic investment in Vigil that included the exclusive right of first negotiation for an exclusive license, grant, or transfer of rights to research, develop, manufacture, and commercialize VG-3927. 

The companies expect the transaction to close in Q3 2025. The acquisition will not have an impact on Sanofi’s financial guidance for 2025.
