Vaccinex, Inc. Presents Overview of the Clinical Development of VX15 (pepinemab) for the Potential Treatment of Huntington’s Disease at the Huntington Study Group’s 2018 Annual Meeting

Presentation and Poster Include Previously Announced Results of Cohort A of SIGNAL Trial

ROCHESTER, N.Y., Nov. 12, 2018 (GLOBE NEWSWIRE) — Vaccinex, Inc. (Nasdaq: VCNX), a clinical-stage biotechnology company engaged in the discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs, including cancer, neurodegenerative diseases, and autoimmune disorders, today announces details of a presentation and poster on November 8th and 9th at the Huntington Study Group’s 25th Annual Meeting: HSG 2018 in Houston, Tex.

Both the presentation and the poster outlined the action of VX15 (pepinemab) anti-semaphorin 4D antibody as ameliorating the neurodegenerative processes in preclinical and clinical studies.  The company has completed and analyzed data from Cohort A the SIGNAL trial, and expects to complete enrollment in Cohort B, a randomized, double-blind, placebo-controlled phase 2 study of VX15 (pepinemab) in approximately 260 patients with Huntington’s Disease.  Endpoints include quantitative cognitive and motor assessments and functional and patient-reported outcomes, as well as imaging measures of change in energy metabolism and volumetric MRI in defined brain regions.

The first cohort enrolled 36 patients, with all subjects either crossing over to or continuing with VX15 (pepinemab) treatment after 6 months.  To date, evaluated patients showed no concerning safety signals and biomarker imaging results have been encouraging.  In addition to safety and imaging, Cohort A data following 11 months of treatment and three months of safety follow up provided the company with important guidance in the design of the second cohort of the trial.

“As we continue enrollment into the second cohort of the SIGNAL trial, we are heartened by the potential for VX15 (pepinemab) in treating Huntington’s Disease, a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain in more than 30,000 symptomatic Americans and more than 200,000 at-risk of inheriting the disease,” commented Maurice Zauderer, CEO of Vaccinex, Inc.  “We look forward to providing updates on our progress in the trial as they become available.”
