WATERTOWN, Mass., Sept. 08, 2023 (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, today announced that it has received notification from the U.S. Food and Drug Administration (FDA) regarding its Investigational New Drug (IND) application to evaluate the Company’s oral small molecule TREM2 agonist VG-3927. The IND for VG-3927 is now open and the Company’s Phase 1 clinical trial in healthy volunteers is allowed to proceed with a partial clinical hold related to maximum exposure limit. At this time, the Company does not anticipate any delay in the current clinical development plans for VG-3927 and expects to commence dosing of the Phase 1 trial evaluating VG-3927 in healthy volunteers in October 2023.
Per the notification, the FDA has limited the maximum exposure of VG-3927 in healthy volunteers in the planned Phase 1 clinical trial. Based on preclinical studies, the Company believes that the maximum exposure limit exceeds the predicted efficacious dose of VG-3927. From the initial comments received from the FDA, the Company believes that the partial clinical hold was not a result of any preclinical toxicology findings or TREM2 pharmacology. The Company expects to receive additional details from the FDA within the next 30 days and will work closely with the FDA to address the partial clinical hold.
The Company also announced today that it will host a virtual R&D event highlighting its small molecule TREM2 agonist program for AD on Wednesday, September 13, 2023, from 7:30 a.m. to 9:00 a.m. ET.
The event will highlight new preclinical data for VG-3927, discuss current treatment approaches for AD, and Vigil’s TREM2-focused clinical approach for treating AD guided by its precision medicine strategy. Vigil’s management team will be joined by:
- Marco Colonna, M.D., Robert Rock Belliveau Professor of Pathology & Immunology, Washington University School of Medicine. Vigil Neuroscience Scientific Advisory Board Chairman; and,
- Samuel E. Gandy, Ph.D., M.D., Mount Sinai Professor of Alzheimer’s Disease Research, Professor of Neurology & Psychiatry and Associate Director of Mount Sinai Alzheimer’s Disease Research Center. Past Chairman, National Medical & Scientific Advisory Council of the Alzheimer’s Association.

About VG-3927
Vigil’s highly active, selective, and brain-penetrant small molecule TREM2 agonist, VG-3927, is designed to act as a molecular glue that potentiates the TREM2 signaling response to natural damage ligands. In preclinical studies, Vigil has established that VG-3927 demonstrated on-target TREM2 activation across both common and rare TREM2 variants. Additionally, VG-3927 demonstrated preclinically that it was able to deliver in vivo TREM2 responses within the central nervous system at a magnitude and specificity similar to VGL101.
About Vigil Neuroscience
Vigil Neuroscience is a clinical-stage biotechnology company focused on developing treatments for both rare and common neurodegenerative diseases by restoring the vigilance of microglia, the sentinel immune cells of the brain. We are utilizing the tools of modern neuroscience drug development across multiple therapeutic modalities in our efforts to develop precision-based therapies to improve the lives of patients and their families. VGL101, our lead clinical candidate, is a fully human monoclonal antibody agonist targeting human triggering receptor expressed on myeloid cells 2 (TREM2) in people with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), a rare and fatal neurodegenerative disease. We are also developing VG-3927, a novel small molecule TREM2 agonist, to treat common neurodegenerative diseases associated with microglial dysfunction, with an initial focus on Alzheimer’s disease (AD) in genetically defined subpopulations.
