ROCHESTER, N.Y., March 21, 2023 (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 the initiation of a single-arm open label, Phase Ib\/2 study to evaluate pepinemab in combination with avelumab as second line combination immunotherapy for patients with metastatic pancreatic adenocarcinoma (PDAC)<\/strong>, NCT05102721.<\/p>\n

The principal goal of this proof-of-concept study is to investigate the safety and efficacy of the combination of pepinemab and the PD-L1 immune checkpoint inhibitor (ICI), avelumab, in patients with PDAC, with particular attention to changes in the tumor microenvironment.<\/p>\n

\u201cWe are very pleased to be working with Dr. David Linehan and his team at the University of Rochester Cancer Center and Wilmot Cancer Institute to conduct this important proof-of-concept study evaluating pepinemab and avelumab in PDAC. The team received a grant from the Gateway Discovery Award<\/strong>to support the trial<\/strong> concept,\u201d said Maurice Zauderer, CEO of Vaccinex. \u201cMetastatic pancreatic adenocarcinoma is the third leading cause of cancer-related deaths. The profoundly immunosuppressive tumor microenvironment (TME) in PDAC remains a significant barrier to effective cytotoxic and immune based therapies. Low response rates to current chemotherapy regimens are evidenced by a 5-year survival rate of only 5-10%, underscoring the significant need for new treatment options. We believe that pepinemab has demonstrated<\/a> a favorable safety profile when used in combination with the immune checkpoint inhibitor (ICI) avelumab1<\/sup>, and the combination may represent a novel treatment option for patients with this devastating disease.\u201d<\/p>\n

Dr. Zauderer continued, \u201cThe hypothesis for evaluating pepinemab in combination with ICIs in PDAC is supported by a robust body of preclinical studies and human clinical data. These data suggest that treatment with the semaphorin 4D (SEMA4D) blocking antibody, pepinemab, may reverse immunosuppression to promote the infiltration and activation of dendritic cells and CD8+ cells into the TME, rendering \u201ccold\u201d tumors \u201chot\u201d and leading to enhanced efficacy of ICIs such as avelumab.\u201d<\/p>\n

Dr. Luis Ruffolo, MD, University of Rochester Medical Center, will be presenting details of these PDAC studies at SSO 2023, International Conference on Surgical Cancer Care in Boston, MA on March 23.<\/p>\n

\n Potential Mechanism of Action for pepinemab in combination with ICIs in PDAC<\/strong>
\n
Tumors that are characterized by a high level of immunosuppressive myeloid cells may be potential candidates for treatment with pepinemab. The tumor microenvironment (TME) of PDAC is characterized by dense fibrotic tissue and abundance of highly suppressive myeloid cells that creates an immunologically \u201ccold\u201d setting with a minimal adaptive T-cell response that limit the efficacy of immune therapies.<\/p>\n

In PDAC, both SEMA4D and PD-1 are expressed on CD8+T cells in the TME. Myeloid cells within the TME express a high level of SEMA4D receptors and signaling through this pathway induces their suppressive activity. This suggests that blocking SEMA4D may represent a novel immunotherapeutic strategy for PDAC. In preclinical oncogene driven PDAC tumor models, treatment with Sema4D blocking antibody in combination with immune checkpoint blockade and standard of care chemotherapy increased penetration of effector T cells and improved response to treatment.<\/p>\n

These observations in PDAC are consistent with a large body of preclinical and clinical data showing that pepinemab promotes infiltration and activation of dendritic cells and CD8+ T-cells and reverses immunosuppression within the tumor microenvironment.<\/p>\n

\n About the Phase 1b\/2 Study in Patients with PDAC<\/strong>
\n
The single-arm, open label Phase 1b\/2 study was designed to evaluate the use of pepinemab, a humanized IgG4 monoclonal antibody that inhibits SEMA4D, in combination with the anti-PD-L1 immune checkpoint inhibitor (ICI), avelumab, as second line treatment for patients with metastatic pancreatic adenocarcinoma who have received first line treatment with either 5-floururacil (5-FU) or gemcitabine.<\/p>\n

The trial was designed at the ASCO-AACR Clinical Trial workshop to integrate evaluation of safety and efficacy. The study will be conducted in two segments utilizing a Simon two-stage design. The Phase 1b stage is intended to establish the tolerability (defined as the maximally tolerated dose) of the combination. Phase 2 begins after 16 subjects are enrolled at the recommended Phase2 dose and successful completion of futility evaluation in Phase 1b. The Phase 2 expansion stage is intended to assess the efficacy of the combination therapy. Efficacy, defined as objective response rate, will be assessed by RECIST1.1 criteria and iRECIST. When combined with the 16 patients from the Phase 1b segment, the overall study cohort will have an evaluable sample of 40 patients. Robust correlative analysis of TME and genomic profiling of tumor biopsies will be conducted to ascertain mechanisms of treatment response and failure.<\/p>\n

Vaccinex\u00a0has global commercial and development rights to pepinemab. The Company is the sponsor of the study which is being primarily funded by a grant from the Gateway Discovery Award (administered by the Conquer Cancer Foundation\/ASCO). Pepinemab is being provided by Vaccinex and avelumab\/BAVENCIO is being provided by Merck KGaA. Additional information about the study is available at:\u00a0clinicaltrials.gov.<\/a><\/p>\n

\n About Vaccinex, Inc. <\/strong>
\n
Vaccinex, Inc.\u00a0is pioneering a differentiated approach to treating cancer and slowly progressive neurodegenerative diseases (NDD) through the inhibition of semaphorin 4D (SEMA4D). The Company\u2019s 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. In oncology, pepinemab is being evaluated in combination with KEYTRUDA\u00ae<\/sup>\u00a0in the Phase 1b\/2 KEYNOTE B-84 study in recurrent or metastatic head and neck cancer (R\/M HNSCC) and in combination with avelumab in a Phase 1b\/2 study in patients with metastatic pancreatic adenocarcinoma (PDAC). The oncology clinical program also includes several investigator-sponsored studies in solid tumors including breast and melanoma. In NDD, pepinemab is being studied as a monotherapy in a Phase 1\/2a study in the SIGNAL-AD Alzheimer\u2019s Disease study, with ongoing exploration of potential Phase 3 development in Huntington\u2019s disease. The Company has also developed a proprietary drug discovery platform, ActivMAb\u00ae<\/sup>, that it is leveraging through strategic collaborations, particularly by applying its unique capability to select high value antibodies against important multi-pass membrane receptors.<\/p>\n
