Company Has Reassured Nasdaq of Actions It Plans to Take to Meet Minimum Bid Price Requirement

Randomized Phase 2 Study in Alzheimer’s Disease on Schedule to Complete Treatment in June 2024

ROCHESTER, N.Y., Dec. 04, 2023 (GLOBE NEWSWIRE) -- Vaccinex, Inc. (Nasdaq: VCNX), a clinical-stage biotechnology company pioneering a differentiated approach to treating Alzheimer’s disease and cancer, previously reported that on October 10, 2023 it was advised by Nasdaq that the Company was no longer in compliance with Nasdaq’s minimum bid price requirement and that Nasdaq could move to suspend trading of the common stock and to delist the Company’s securities unless the company appealed Nasdaq’s determination. The Company appealed that decision and has been granted an exception until March 4, 2024 to address this issue. Subject to fulfilling its commitments to Nasdaq, it is expected that Vaccinex shares will continue to be listed on the Nasdaq Capital Market throughout this time and subsequently if compliance is restored.

Vaccinex continues to advance its key programs with particular focus on a potential near-term catalyst, the randomized phase 2 trial of its pepinemab antibody to counter neuroinflammation in Alzheimer’s disease (AD). The last patient in this trial is expected to complete the planned 12-months of treatment by early June 2024. Key endpoints include brain metabolic activity, a recognized biomarker of clinical progression in AD, as well as treatment effects on cognition employing several validated, clinically meaningful Alzheimer’s cognitive scales.

Investors will recall that Vaccinex has previously completed a randomized phase 2 study in Huntington’s disease (HD) in which it was demonstrated that pepinemab treatment significantly reduced characteristic decline in brain metabolic activity as measured by FDG-PET imaging and also reduced or prevented cognitive decline. There are numerous physiological parallels between neurodegenerative processes in Alzheimer’s and Huntington’s disease. A key common feature is the contribution of reactive astrocytes (astrogliosis) to brain inflammation and damage. Vaccinex scientists have demonstrated that the stress of disease in both AD and HD leads to upregulation of SEMA4D in neurons that can trigger astrogliosis resulting in a loss of normal supportive physiological functions such as brain metabolic activity and a gain of inflammatory activity marked by release of glial fibrillary acidic protein (GFAP) into the blood. Importantly, treatment with pepinemab in HD patients was shown to reverse disease associated changes in these two biomarkers, which we believe is evidence that pepinemab prevents astrocyte activation. Elevated plasma GFAP levels have also been reported to correlate with Aβ amyloid deposits in brain of patients with AD and to be associated with higher risk of dementia and faster rates of cognitive decline. We believe that these findings portend a potentially favorable clinical outcome for pepinemab treatment in AD.

About Pepinemab
Pepinemab is a humanized IgG4 monoclonal antibody designed to block SEMA4D, which can trigger collapse of the actin cytoskeleton and loss of homeostatic functions of astrocytes and other glial cells in the brain and of innate immune cells that regulate immune responses. Pepinemab has been administered to more than 400 patients and appears to be well-tolerated and to have a favorable safety profile.

About Vaccinex Inc. 
Vaccinex, Inc. is pioneering a differentiated approach to treating slowly progressive neurodegenerative diseases and cancer through the inhibition of semaphorin 4D (SEMA4D). The Company’s lead drug candidate, pepinemab, blocks SEMA4D, a potent biological effector that it believes triggers damaging inflammation in chronic diseases of the brain and prevents immune infiltration into tumors. In neurodegenerative diseases, pepinemab is being studied as a monotherapy in the Phase 1/2a SIGNAL-AD study in Alzheimer’s Disease, with ongoing exploration of potential Phase 3 development in Huntington’s disease. In oncology, pepinemab is being evaluated in combination with KEYTRUDA® in the Phase 1b/2 KEYNOTE-B84 study in recurrent or metastatic head and neck cancer (HNSCC) and in combination with BAVENCIO® in a Phase 1b/2 study, supported by funding from Gateway Discovery Foundation, in patients with metastatic pancreatic adenocarcinoma (PDAC). The oncology clinical program also includes several investigator-sponsored studies in solid tumors including breast cancer and melanoma.

Vaccinex has global commercial and development rights to pepinemab and is the 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. Additional information about the study is available at: clinicaltrials.gov.

KEYTRUDA is a registered trademark of Merck Sharp & Dohme Corp., a subsidiary of Merck & Co. Inc., Kenilworth, NJ, USA.

BAVENCIO®/avelumab is provided by Merck KGaA, Darmstadt, Germany, previously as part of an alliance between the healthcare business of Merck KGaA and Pfizer.
