Vigil Neuroscience (VIGL) Files IPO Registration Statement

Vigil Neuroscience (NASDAQ: VIGL) has filed for a proposed IPO.

The company describes itself as: "We are a microglia-focused company dedicated to improving the lives of patients, caregivers and families affected by rare and common neurodegenerative diseases by pursuing the development of disease-modifying therapeutics to restore the vigilance of microglia. Microglia are the sentinel immune cells of the brain and play a critical role in maintaining central nervous system (CNS) health and responding to damage caused by disease. Leveraging recent research implicating microglial dysfunction in neurodegenerative diseases, we utilize a precision medicine approach to develop a pipeline of therapeutic candidates, initially addressing genetically defined patient subpopulations, that we believe will activate and restore microglial function. Our first therapeutic candidates are designed to activate Triggering Receptor Expressed on Myeloid Cells 2 (TREM2), a key microglial receptor protein that mediates responses to environmental signals in order to maintain brain health and whose dysfunction is linked to neurodegeneration. Our lead candidate, VGL101, is a fully human monoclonal antibody (mAb) that is designed to activate TREM2. In November 2021, the FDA cleared our Investigational New Drug application (IND) for VGL101 in ALSP at doses up to 20 mg/kg. We plan to begin our first-in-human Phase 1 clinical trial with VGL101 in healthy volunteers in December 2021 and expect to complete it in the second half of 2022. We are initially developing VGL101 for the treatment of adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), a rare, genetically defined, and fatal neurodegenerative disease caused by microglial dysfunction. We intend to expand development of VGL101 for the treatment of additional rare leukoencephalopathies and leukodystrophies in which microglia play an essential role, including cerebral adrenoleukodystrophy (cALD). We are also developing a novel small molecule TREM2 agonist suitable for oral delivery to treat common neurodegenerative diseases associated with microglial dysfunction. The initial focus of our novel small molecule TREM2 agonist program is for the treatment of Alzheimer’s disease (AD) in genetically defined patient subpopulations. We expect to select a development candidate by the first quarter of 2022 and, following IND-enabling studies, plan to initiate a first-in-human healthy volunteer trial. We believe our microglia focus, precision medicine approach, and pipeline, which spans multiple modalities, strongly position us to become a differentiated leader in the neurodegenerative therapeutic space."

Morgan Stanley, Jefferies, Stifel and Guggenheim Securities will serve as underwriters.
