Phase 2 SIGNAL-HD Study Published in Nature Medicine
Patient enrollment continues in the Phase 1/2a SIGNAL-AD Alzheimer’s study
ROCHESTER, N.Y., Aug. 15, 2022 (GLOBE NEWSWIRE) -- Vaccinex, Inc. (Nasdaq: VCNX), a clinical-stage biotechnology company pioneering a differentiated approach to treating cancer and neurodegenerative disease through the inhibition of SEMA4D, today announced financial results for the second quarter ended June 30, 2022 and provided a corporate update on key events since April, 2022 (the last 5 months).
“Vaccinex has made excellent progress this year in its clinical programs to evaluate the potential use of our proprietary SEMA4D inhibitor, pepinemab, in oncology and neurodegenerative disease,” said Maurice Zauderer, Ph.D., President and Chief Executive Officer of Vaccinex. “We have previously reported several promising responses in the open label, Phase 1b/2 KEYNOTE oncology B84 trial to evaluate pepinemab and KEYTRUDA® (pembrolizumab, a PD-1 inhibitor) in patients with advanced recurrent or metastatic head and neck cancer (R/M HNSCC). An expanded interim analysis of study data is planned in Q4 2022. With continued positive results, we are hopeful that this combination could be a promising treatment option for patients with R/M HNSCC who have limited treatment choices,”
Dr. Zauderer continued, “Vaccinex is also very pleased to announce the recent publication of the results of the Phase 2 SIGNAL study of pepinemab in Huntington’s Disease (HD) in Nature Medicine. This is an important milestone for the neurodegenerative disease program. While, as previously reported, the study did not meet its pre-specified primary endpoints, we believe the results provide compelling signals of cognitive benefit, evidenced by multiple exploratory and post-hoc efficacy assessments, and support further development in HD and other neurodegenerative indications including Alzheimer’s disease. Importantly, treatment resulted in a statistically significant increase in brain metabolic activity (measured by FDG-PET) in 15 of 26 brain regions of patients with Early Manifest HD. Multiple studies have shown that reduced FDG-PET signal correlates with cognitive decline and clinical progression in Alzheimer’s Disease (AD). Based on these observations, we are excited to have initiated the randomized, double-blind, Phase 1/2a SIGNAL-AD study in 40 subjects with early AD. We expect this study will complete enrollment by Q1 2023.”
Dr. Zauderer continued, “Vaccinex’s clinical programs in oncology and neurodegenerative disease are poised to yield important data over the next twelve to eighteen months. We look forward to updating the clinical community and investors on our progress and thank all of the patients, caregivers, and participating clinical sites and investigators for their continued support of these promising clinical programs.”

Pepinemab Program Overview:
Oncology: Head and Neck Cancer
Rationale: Multiple prior studies suggest that inhibition of SEMA4D increases immune infiltration and alters the balance of cytotoxic and immunosuppressive cells in the tumor microenvironment. As SEMA4D is highly expressed in head and neck cancer, there is strong rationale for development in this indication.
Status: Enrollment is underway in the Phase 1b/2 KEYNOTE B84 clinical study evaluating pepinemab in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in recurrent or metastatic head and neck cancer. The study was designed to enroll up to 65 subjects across 18 U.S. trial sites to assess safety and efficacy of the combination pepinemab/pembrolizumab. Key endpoints of the study will include objective response, duration of response and overall survival.
Vaccinex has exclusive global commercial and development rights to pepinemab and is a sponsor of the KEYNOTE-B84 study which is being performed in collaboration with Merck Sharp & Dohme Corp, a subsidiary of Merck and Co, Inc. Kenilworth, NJ, USA. KEYTRUDA is a registered trademark of Merck Sharp & Dohme Corp., a subsidiary of Merck & Co. Inc., Kenilworth, NJ, USA.
Other Trials. Pepinemab is also being evaluated in multiple investigator-sponsored trials (ISTs) being conducted by the Winship Cancer Institute of Emory University to evaluate pepinemab in combination with checkpoint inhibitors in “Window of Opportunity” biomarker studies of head and neck cancer and melanoma.
Neurodegenerative Disease:
Rationale: SEMA4D appears to be upregulated on damaged neurons in the brains of people with either Huntington’s Disease (HD) or Alzheimer’s Disease (AD), leading to physiological changes in the structure and function of the major inflammatory cells of the brain, astrocytes and microglia, that express receptors for SEMA4D. Preclinical studies conducted by Vaccinex have shown that pepinemab can inhibit SEMA4D and reverse neuroinflammation and restore normal functions associated with astrocytes.
Alzheimer’s Disease: The Phase 1/2a SIGNAL-AD Study. Enrollment is underway in this randomized, double-blind, placebo-controlled, multi-center safety and biomarker study of pepinemab in early AD. The study is planned to enroll 40 subjects across 15 U.S. trial sites. The trial is being funded in part by the Alzheimer’s Drug Discovery Foundation and by the Alzheimer’s Association under their 2020 Part the Cloud Program.
Financial Results for the Three Months Ended June 30, 2022:

Research and Development Expenses. Research and development expenses for the quarter ended June 30, 2021 were
The slight reduction in Research and Development expenses in the period ended June 30, 2022 compared to 2021 is primarily attributed to reduced clinical trial costs as a result of the completion of the CLASSICAL-Lung and SIGNAL studies phase 2 trials, partially offset by setup expenses for the SIGNAL-AD and HNSCC KEYNOTE-B84 studies.
General and Administrative Expenses. General and administrative expenses for the quarter ended June 30, 2022 were
Essentially flat level of general and administrative expenses reflects careful cost control measures.

About Pepinemab
Pepinemab is a humanized IgG4 monoclonal antibody that inhibits SEMA4D, which regulates the actin cytoskeleton of cells that plays an important role in tumor immunity and in inflammatory reactions in the brain. Preclinical and clinical data show that by preventing inflammatory reactivity pepinemab during disease progression, pepinemab preserves normal function of astrocytes and microglia, two types of glial cells that play a crucial role in the development and maintenance of neurons in the brain. Additional data show that pepinemab promotes infiltration and activation of dendritic cells and CD8+ T-cells and reverses immunosuppression within the tumor microenvironment. Pepinemab is being evaluated in several studies in oncology and neurodegenerative disease.
About ActivMAb®
Vaccinex has developed a proprietary mammalian cell-based antibody discovery platform with unique multi-pass membrane target capabilities. The ActivMAb technology now has four main applications: complex membrane antigen presentation, antibody or antigen discovery, and protein optimization. Vaccinex has entered into an antibody license with Surface Oncology (Cambridge, MA) and into Material Transfer Agreements for drug discovery or process development with two major pharma utilizing this technology.
About Vaccinex, Inc.
Vaccinex, Inc. is pioneering a differentiated approach to treating cancer and slowly progressive neurodegenerative diseases through the inhibition of semaphorin 4D (SEMA4D). The Company’s lead drug candidate, pepinemab, blocks SEMA4D, a potent biological effector that it believes prevents immune infiltration into tumors and triggers inflammation in chronic diseases of the brain. Pepinemab is being evaluated in a Phase 1b/2 study in recurrent or metastatic head and neck cancer and in a Phase 1/2a study in Alzheimer’s Disease, with ongoing exploration of potential Phase 3 development in Huntington’s disease. The Company has also developed a proprietary drug discovery platform, ActivMAb®, that it is leveraging thru strategic collaborations, particularly by exploiting its unique capability to select high value antibodies against important multi-pass membrane receptors.
