• Second keynote invitation follows recent peer reviewed publications and growing international recognition of CEL-SCI’s Multikine Phase 3 research
• Multikine neoadjuvant immunotherapy is the first pre-surgery treatment to significantly increase overall survival (OS) of resectable locally advanced head and neck (oral/soft palate) squamous cell carcinoma patients in decades
• Biomarker-based patient selection method that identifies target patient population who can achieve OS benefit is being used in CEL-SCI’s 212-patient Registration Study
• Multikine increased the 5-year survival rate in this target patient population to 73% vs 45% in patients treated with standard of care alone and halved the risk of death from 55% to 27% in the now completed Phase 3 study

VIENNA, Va.--(BUSINESS WIRE)-- CEL-SCI Corporation (NYSE American: CVM) today announced that the Company’s Chief Scientific Officer and Multikine® (Leukocyte Interleukin, Injection)* inventor and developer, Dr. Eyal Talor, has received his second invitation to deliver a keynote address at an international head and neck cancer conference. Dr. Talor has been invited to speak at the 3^rd Global Congress on Otolaryngology, Head and Neck Surgery which will take place on June 9-10, 2027 in Lisbon, Portugal.

Dr. Talor’s presentation, titled “Disease/Tumor Biomarkers Prognosticate Overall Survival Benefit in Oral Squamous Cell Carcinoma: A Novel Neoadjuvant Cancer Immunotherapy” will address findings from CEL-SCI’s Phase 3 study of Multikine and the Company’s work using tumor and disease biomarkers to identify patients most likely to benefit from Multikine treatment before surgery.

This follows Dr. Talor’s recent keynote speech at the 6th World Congress on Otology, Rhinology and Laryngology in Rome on October 26. Both invitations came after recent peer-reviewed publications of CEL-SCI’s IT-MATTERS Phase 3 research. The series of scientific publications and keynote invitations is expanding the visibility of CEL-SCI’s biomarker-based approach among specialists who diagnose and treat head and neck cancer.

“We believe these keynote invitations reflect growing scientific interest in what we have demonstrated with Multikine: the first overall survival advantage for a neoadjuvant treatment in this patient population in many decades, and a biomarker-based method that can identify at diagnosis the patients most likely to achieve this substantial survival benefit,” said CEL-SCI CEO Geert Kersten. “This combination is what makes our findings potentially groundbreaking for head and neck cancer patients. We are now applying this patient selection method prospectively in our Registration Study of 212 patients.”

CEL-SCI’s completed 928-patient IT-MATTERS Phase 3 study identified disease and tumor biomarkers which can be applied at diagnosis to select previously untreated, locally advanced head and neck cancer patients most likely to benefit from neoadjuvant Multikine administration, a pre-surgery treatment. CEL-SCI is applying these biomarkers prospectively as patient selection criteria in its 212-patient Registration Study, which is designed with approximately 97% statistical power to detect the survival effect previously observed in this population.

Surgeons, healthcare professionals, academic scholars and researchers from around the world are expected to participate in the 3rd Global Congress on Otolaryngology, Head and Neck Surgery in Lisbon. The Congress provides a forum for scientific research, surgical advances and clinical developments in otolaryngology and head and neck surgery. The theme of the 2027 Congress is “Transforming ENT Care through Research, Innovation, and Clinical Excellence.”

About Multikine

Multikine is a novel cancer immunotherapy administered before surgery as a treatment for newly diagnosed previously untreated locally advanced head and neck cancer. Its goal is to activate a person’s immune system to fight cancer before the ravages of surgery, radiation and chemotherapy have weakened the immune system. In the world’s largest locally advanced, resectable head and neck cancer Phase 3 study, Multikine increased the 5-year survival rate of the target patient population to 73% vs 45% in patients treated with standard of care alone and halved the risk of death from 55% to 27%. The results of the IT-MATTERS global Phase 3 study represent the first overall survival advantage for a neoadjuvant treatment, in the treatment naïve resectable locally advanced head and neck squamous cell carcinoma (cancer) patients, in many decades.

About CEL-SCI Corporation

CEL-SCI believes that boosting a patient’s immune system before surgery, radiotherapy and chemotherapy have damaged it, should provide the greatest possible impact on survival. Multikine is designed to help the immune system "target" the tumor at a time when the immune system is still relatively intact and thereby thought to be better able to mount an attack on the tumor.

Multikine (Leukocyte Interleukin, Injection), given right after diagnosis and before surgery, has been administered to over 740 patients and has an excellent safety profile compared to other cancer drugs. It has received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck.

The Company has operations in Vienna, Virginia, and near/in Baltimore, Maryland.

Key Terms

neoadjuvant immunotherapy medical

Immunotherapy given before the main definitive treatment—typically surgery—to stimulate the patient’s immune system to attack a tumor, reduce tumor size, and improve the chances of successful removal. It differs from adjuvant immunotherapy (which is given after treatment) and is assessed in trials by measures such as tumor shrinkage or pathologic complete response at the time of surgery, but its effects on long-term outcomes must be demonstrated separately.

overall survival medical

Overall survival is the average or median length of time patients remain alive after starting a treatment or entering a clinical study, measured regardless of cause of death. Investors care because it is a clear, hard measure of a therapy’s real-world benefit — like timing how long a new battery actually runs — and strong improvements in overall survival can drive regulatory approval, market adoption and revenue potential.

squamous cell carcinoma medical

Squamous cell carcinoma is a type of skin cancer that develops when the cells in the outer layer of the skin grow abnormally and uncontrollably. It can also occur in other parts of the body, such as the mouth or throat. For investors, understanding diseases like this is important because they can impact healthcare companies, influence medical research funding, and affect overall public health trends.

biomarkers medical

Biomarkers are measurable indicators found in the body, such as substances in blood or tissues, that reveal information about health or disease. For investors, they can signal how well a medical treatment is working or whether a disease is developing, helping to assess the potential success or risks of healthcare companies or innovations. Think of biomarkers as biological signals that provide clues about a person’s health status.
