Vaccinex reports pepinemab boosts immune response in cancer

ROCHESTER, N.Y. - Vaccinex, Inc. (NASDAQ:VCNX), a clinical-stage biotechnology firm with a market capitalization of $1.98 million, is set to present new data at the American Association for Cancer Research (AACR) Annual Meeting in Chicago on Tuesday, April 29, 2025. According to InvestingPro analysis, the company appears undervalued at its current price of $0.74, despite facing significant cash burn challenges. The data will detail the mechanism by which its drug candidate pepinemab enhances immune responses in cancer therapy, particularly for melanoma and head and neck cancer patients.

The company’s findings suggest that pepinemab, which blocks Semaphorin 4D, plays a crucial role in facilitating immune cell interactions within tertiary lymphoid structures (TLS). These structures are important for amplifying mature T cell responses, which are essential for eradicating tumors. The presence of TLS has been linked to clinical benefits and positive responses to immune checkpoint therapy.

Clinical trials have shown that neoadjuvant treatment with pepinemab, in combination with immune checkpoint inhibitors, enhanced TLS maturity and correlated with longer recurrence-free survival in patients with metastatic melanoma. This development comes as InvestingPro data shows promising growth prospects, with analysts forecasting a 192% revenue increase for fiscal year 2025.

Additionally, pepinemab has demonstrated the potential to transform immunologically "cold" tumors into "hot" immune centers by inducing robust and mature TLS. This is particularly significant for tumors like HPV-negative and PD-L1-low head and neck cancer, which traditionally respond poorly to immunotherapies.

The ongoing evaluation of pepinemab in the neoadjuvant setting for head and neck cancer patients will be reported at an upcoming scientific meeting this spring. Vaccinex believes that the drug may offer a solution to the limitation of identifying safe and effective therapies that can induce the formation of TLS.

Pepinemab is a humanized IgG4 monoclonal antibody designed to inhibit the biological effects of SEMA4D. It has shown a favorable safety profile in various clinical trials across different cancer and neurological indications.

The upcoming AACR presentations by Elizabeth Evans, PhD, Senior VP of Discovery and Translational Medicine at Vaccinex, will shed further light on the clinical outcomes, biomarkers, and mechanisms of interactions in patients treated with pepinemab in combination with immune checkpoint therapy.

This announcement is based on a press release statement from Vaccinex, Inc. and aims to provide insights into the potential advancements in cancer immunotherapy. Vaccinex continues to evaluate pepinemab in collaboration with industry partners and maintains global commercial and development rights to the drug candidate.
