WATERTOWN, Mass., May 07, 2024 (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 first quarter ended March 31, 2024, and provided an update on recent progress.

“During the quarter, we continued to progress iluzanebart, our monoclonal antibody, and VG-3927, our oral small molecule, through development and are well-positioned to deliver two value-driving data readouts from our clinical programs in 2024,” said Ivana Magovčević-Liebisch, Ph.D., J.D., President and Chief Executive Officer of Vigil. “These data will deliver important insights on TREM2 agonism in rare and common neurodegenerative diseases and will further support our commitment and mission to address the treatment needs for patients as quickly as possible.”

Recent Updates and Anticipated Milestones

Iluzanebart, Monoclonal Antibody TREM2 Agonist

  • Completed enrollment for Phase 2 IGNITE clinical trial: The Company completed enrollment of its IGNITE Phase 2 clinical trial in March 2024 with 20 patients enrolled in the trial, exceeding the initially planned 15 patients.
  • Presented key findings from ALSP studies at 2024 American Academy of Neurology Annual Meeting: Interim data from the first six patients following six months of treatment with 20 mg/kg of iluzanebart from the Company’s Phase 2 IGNITE proof-of-concept clinical trial in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) were presented in an oral presentation. In addition, two posters highlighting the ILLUMINATE Natural History Study of ALSP and the mechanism of action for iluzanebart were also presented. The posters and presentation can be accessed on the publications page of the Company’s website.
  • Next data readout from Phase 2 IGNITE clinical trial on track for third quarter of 2024: The Company is on track to report additional data from its Phase 2 clinical trial evaluating iluzanebart in ALSP in the third quarter of 2024. The analysis will include 12-month follow-up data from patients in the 20 mg/kg dose cohort and data from patients in the 40 mg/kg dose cohort who have completed 6 months.

VG-3927, Small Molecule TREM2 Agonist

  • Interim healthy volunteer data from Phase 1 clinical trial planned for mid-2024: The Company plans to report interim healthy volunteer data from the Phase 1 clinical trial evaluating VG-3927 for the treatment of Alzheimer’s disease (AD) in mid-2024. The Company plans to add a cohort of patients with AD in the Phase 1 trial to explore a biomarker response of VG-3927. The cohort will include genetically defined subpopulations of AD, including those who carry TREM2 and other variants. The Company will use these data to inform patient selection and the development strategy for its subsequent, larger trials in AD.


  • Appointment of biotech industry executive Petra Kaufmann, M.D., M.S., F.A.A.N, as Chief Medical Officer: The Company recently announced the appointment of Petra Kaufmann, M.D., M.S., F.A.A.N, as Chief Medical Officer. Dr. Kaufmann brings over 25 years of expertise in neurological and rare diseases and a track record of global drug development in transformative and innovative therapies.

First Quarter 2024 Financial Results

  • Cash Position: Cash, cash equivalents, and marketable securities were $101.6 million as of March 31, 2024, compared to $117.9 million as of December 31, 2023. The Company expects its cash, cash equivalents and marketable securities to fund its operational plans into the second half of 2025.
  • Research and Development (R&D) Expenses: R&D expenses for the first quarter ended March 31, 2024 were $14.3 million, compared to $13.8 million for the same period in 2023. This increase was driven by increased operational costs to support the progression of the Company’s pipeline.
  • General and Administrative (G&A) Expenses: G&A expenses for the first quarter ended March 31, 2024 were $7.1 million, which is consistent with the $6.9 million for the same period in 2023.
  • Net Loss: Loss from operations for the first quarter ended March 31, 2024 were $19.9 million, compared to $19.8 million for the same period in 2023.

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. Vigil is utilizing the tools of modern neuroscience drug development across multiple therapeutic modalities in its efforts to develop precision-based therapies to improve the lives of patients and their families. Iluzanebart, Vigil’s 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. Vigil is 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.
