Frequently asked questions about VG-3927

What is VG-3927?

VG-3927 is an investigational small molecule being developed by Vigil Neuroscience, Inc. for Alzheimer disease. It is designed to target TREM2, a protein involved in microglial function in the brain. VG-3927 has completed a Phase 1 clinical trial and is not approved for any indication.

What is VG-3927 used for in Alzheimer disease?

VG-3927 is being developed as a potential treatment for Alzheimer disease. It is an investigational therapy that has completed Phase 1 testing in healthy adults and patients with Alzheimer disease. It has not been approved by the FDA for Alzheimer disease or any other condition.

What does VG-3927 target?

VG-3927 targets TREM2, a protein expressed on microglia in the central nervous system. TREM2 is involved in microglial activation and phagocytosis, processes implicated in Alzheimer disease pathology. By targeting TREM2, VG-3927 aims to modulate neuroinflammatory responses associated with the disease.

Who is developing VG-3927?

VG-3927 is being developed by Vigil Neuroscience, Inc., a biotechnology company traded on the Nasdaq under the ticker symbol VIGL. Vigil Neuroscience focuses on developing therapies for neurodegenerative diseases, and VG-3927 is its small molecule candidate targeting TREM2 for Alzheimer disease.

What phase is VG-3927 in?

VG-3927 has completed a Phase 1 clinical trial. The trial, NCT06343636, was a randomized, double-blind, placebo-controlled study that enrolled 115 participants, including healthy adults and patients with Alzheimer disease, in the United States and Australia. VG-3927 remains investigational and has not been approved by the FDA.

What clinical trials is VG-3927 in?

VG-3927 has been evaluated in one completed Phase 1 clinical trial, NCT06343636, titled "A Phase 1 Study of VG-3927 in Healthy Adults and Patients With Alzheimer's Disease." The trial enrolled 115 participants across the United States and Australia and was randomized, double-blind, and placebo-controlled.
