WATERTOWN, Mass., March 13, 2025 (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 financial results for the fourth quarter and full year ended December 31, 2024, and provided updates on recent progress.

“We are entering 2025 with strong momentum, driven by significant progress in the development of our TREM2 programs, VG-3927 and iluzanebart,” said Ivana Magovčević-Liebisch, Ph.D., J.D., President and Chief Executive Officer of Vigil. “We recently reported positive Phase 1 data for VG-3927 that support the advancement of this differentiated clinical candidate, and we plan to initiate the Phase 2 trial in the third quarter of 2025. As the first and only, Phase 2-ready oral small molecule TREM2 agonist, VG-3927 has the potential to provide a novel, next-generation therapy for Alzheimer’s disease. Additionally, with the upcoming Phase 2 data readout for iluzanebart in ALSP in the second quarter we are excited to advance closer to providing a potential breakthrough therapy for this devastating disease with serious unmet need. With a number of upcoming catalysts for our two TREM2 agonist programs, 2025 is set to be a pivotal year for Vigil.”

Recent Business Highlights and Upcoming Milestones

Iluzanebart, Monoclonal Antibody TREM2 Agonist

Final analysis from IGNITE Phase 2 clinical trial planned for second quarter of 2025:

  • The Company plans to report the final analysis from the IGNITE Phase 2 clinical trial, including all patients at 12 months dosed with either 20 mg/kg or 40 mg/kg of iluzanebart in the second quarter of 2025.

  • The Company intends to pursue an accelerated approval pathway for iluzanebart in ALSP and expects to share an update on its progress when the final analysis is reported.

VG-3927, Small Molecule TREM2 Agonist

Positive Phase 1 data from VG-3927:

  • In January 2025, the Company reported positive data from its completed Phase 1 clinical trial evaluating VG-3927 for the potential treatment of AD. The Phase 1 single and multiple ascending dose (SAD/MAD) trial assessed the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of VG-3927 across 14 cohorts, including 8 SAD cohorts of healthy volunteers up to a 140 mg dose and 4 MAD cohorts of healthy volunteers up to a 50 mg dose. The trial also included a multiple dose elderly cohort and a single dose cohort of AD patients, including some participants who carry TREM2 or other genetic risk factors for AD. The trial enrolled a total of 115 participants with 89 participants receiving VG-3927, including 34 participants that were 55 years of age and older.

  • These data demonstrated a favorable safety and tolerability profile across all cohorts, including the elderly cohort. All related adverse events were mild or moderate in severity and self-resolving without drug discontinuations. No serious AEs were reported.

  • VG-3927 was observed to be highly CNS penetrant with a favorable and predictable PK profile that supports once-daily dosing. Importantly, VG-3927 achieved a robust and dose-dependent reduction of sTREM2 of up to approximately 50% in the cerebral spinal fluid (CSF) demonstrating a strong PK/PD relationship, sustained target engagement and TREM2 agonist activity.

  • Vigil will present the Phase 1 data in an oral presentation at the AD/PD™ 2025 International Conference on Alzheimer’s and Parkinson’s Disease taking place April 1-5, 2025, in Vienna, Austria and virtually.

  • The Company plans to advance a once-daily oral dose of 25 mg that fully engages the desired pharmacology and expects to initiate the Phase 2 trial in the third quarter of 2025.
