CAMBRIDGE, Mass., Nov. 01, 2022 (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 the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to VGL101 for the treatment of patients with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP). VGL101, Vigil’s lead product candidate, is a monoclonal antibody TREM2 agonist currently being evaluated in a Phase 1 trial in healthy volunteers.

“ALSP is a devastating disease that affects an estimated 10,000 people in the US with no approved treatments. We believe this Fast Track designation by the FDA recognizes the significant unmet need of ALSP patients and the therapeutic potential of VGL101,” said Ivana Magovčević-Liebisch, Ph.D., J.D., President and Chief Executive Officer of Vigil. “We are excited about the progress we’ve made in advancing VGL101 and we remain on track to report Phase 1 topline data and to initiate a Phase 2 proof-of-concept trial for VGL101 in ALSP this quarter.”

Fast Track designation is designed to facilitate development and expedite the review of therapies for serious conditions, such as ALSP, and fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communications with the FDA as well as the potential for priority review and a rolling submission of the marketing application.

About VGL101
VGL101, Vigil’s lead product candidate, is a fully human monoclonal antibody targeting human triggering receptor expressed on myeloid cells 2 (TREM2), which is responsible for maintaining microglial cell function. TREM2 deficiency is believed to be a driver of certain neurodegenerative diseases. VGL101 is in development for the treatment of rare microgliopathies, such as ALSP, as well as other neurodegenerative diseases for which TREM2 and/or microglia deficiency is believed to be a key driver of disease pathway.
