Expect Topline Data for Phase 1/2a Randomized SIGNAL-AD Study of Pepinemab for Alzheimer’s Disease in Q3 2024
Company raised
Alzheimer’s Disease (AD):
- In
June 2024 , anticipate completing planned 12-months treatment of patients with mild Alzheimer’s disease in the randomized, double-blind, Phase 1b/2a SIGNAL-AD trial of pepinemab vs placebo (NCT04381468). This study was funded in part by the Alzheimer’sDrug Discovery Foundation and by a grant from the Alzheimer’s Association. Topline data is expected in Q3 2024. - Following last patient last visit we will evaluate the impact of treatment on brain metabolic activity, a key biomarker of clinical progression in AD, together with other biomarkers of disease progression and initial assessment of treatment effects on cognition employing several validated, clinically meaningful cognitive scales for AD.
- An improving AD-drug development environment, based on FDA’s recent full approval of LEQEMBI®, enables the pathway to reimbursement and supports partnering and further investment in Alzheimer’s Disease drug development.
- As previously reported, pepinemab has a differentiated mechanism of action, blocking SEMA4D, which is upregulated in neurons during stress of Alzheimer’s and Huntington’s disease and triggers the transformation of astrocytes and microglia from normal homeostatic functions to neuroinflammatory activity. Blockade of SEMA4D is believed to reduce neuroinflammation and to protect and restore healthy astrocyte and neuronal functions (Nature Medicine 2022, https://doi.org/10.1038/s41591-022-01919-8).
- We believe that the prevalence of AD (6 million people diagnosed with AD in the US alone) and current concerns about the limitations of anti-Aβ amyloid antibodies would make pepinemab attractive as a potential alternative to anti-Aβ antibodies or possibly for use in combination with anti-Aβ for greater efficacy.
Head and Neck Cancer:
- As previously reported, analysis of interim data from the first 36 patients in the single-arm, Phase 2 KEYNOTE-B84 study (NCT04815720) evaluating pepinemab in combination with KEYTRUDA™ in patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) suggests that the combination treatment resulted in an approximately 2X increase in objective responses (ORR) and progression free survival (PFS) in the subset of patients with hard-to-treat PD-L1-low tumors compared to historical response rates for checkpoint monotherapy in this population.
- Biomarker data indicate that treatment induced the formation of highly organized lymphoid aggregates in tumor that correlate with disease control and have previously been shown to be predictive of positive response to checkpoint inhibitors.
- Further research has suggested strategies to exploit this unique feature of pepinemab treatment in combination with KEYTRUDA so as to further enhance and expand treatment benefit. This will be the focus of continuing development.

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 glial cells in the brain and dendritic cells in immune tissue. Over 600 patients have been treated or enrolled in clinical trials of pepinemab in different indications and pepinemab appears to be well-tolerated and to have a favorable safety profile.
About Vaccinex Inc.
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.

Forward Looking Statements
To the extent that statements contained in this presentation are not descriptions of historical facts regarding Vaccinex, Inc. (“Vaccinex,” “we,” “us,” or “our”), they are forward-looking statements reflecting management’s current beliefs and expectations. Such statements include, but are not limited to, statements about expectations and objectives with respect to the results and timing of the SIGNAL-AD clinical trial; our plans, expectations and objectives with respect to the results and timing of the KEYNOTE-B84 clinical trial; the use and potential benefits of pepinemab in R/M HNSCC, lung cancer, metastatic pancreatic adenocarcinoma (PDAC) and other indications; the potential for benefits as compared to single agent KEYTRUDA® or BAVENCIO®; expectations with respect to the collaboration of Merck; the potential to initiate a Phase 3 trial in Huntington’s Disease; and other statements identified by words such as “believe,” “being,” “will,” “appears,” “expect,” “ongoing,” “potential,” “suggest”, and similar expressions or their negatives (as well as other words and expressions referencing future events, conditions, or circumstances). Forward-looking statements involve substantial risks and uncertainties that could cause the outcome of our research and pre-clinical development programs, clinical development programs, future results, performance, or achievements to differ significantly from those expressed or implied by the forward-looking statements. Such risks and uncertainties include, among others, uncertainties inherent in the execution, cost and completion of preclinical studies and clinical trials, that interim and preliminary data may not be predictive of final results and does not ensure success in later clinical trials, uncertainties related to regulatory approval, risks related to our dependence on our lead product candidate pepinemab, the possible delisting of our common stock from NASDAQ if we are unable to regain compliance with the NASDAQ listing standards, and other matters that could affect our development plans or the commercial potential of our product candidates. Except as required by law, we assume no obligation to update these forward-looking statements. For a further discussion of these and other factors that could cause future results to differ materially from any forward-looking statement, see the section titled “Risk Factors” in our periodic reports filed with the Securities and Exchange Commission and the other risks and uncertainties described in the Company’s annual year-end Form 10-K and subsequent filings with the SEC.
