CEL-SCI to Present Novel Data at AHNS 11th International Conference on Head and Neck Cancer—New Patent to Be Filed

CEL-SCI Corporation (NYSE American: CVM) today announced it will present the new data from its pivotal Phase 3 study, the largest study ever conducted in newly diagnosed locally advanced squamous cell carcinoma of the head and neck (SCCHN), at the American Head and Neck Cancer Society’s (AHNS) 11^th Annual International Conference on Head and Neck Cancer on July 8-12, 2023 in Montreal, Canada.

“This data to be presented at AHNS, in our view and also in the view of our clinical consultants, is quite remarkable and has the potential to help many more people than just the study population in our recently concluded Phase 3 clinical trial,” stated CEL-SCI CEO, Geert Kersten. “In fact, these findings are so novel that we are currently preparing to file a new patent application. Details will be announced once the presentation has been given.”

CEL-SCI’s IT-MATTERS pivotal Phase 3 study reported a statistically significant 14.1% absolute 5-year overall survival (OS) benefit in the intent to treat (ITT) subjects who received Multikine followed by surgery and radiotherapy, as compared to control subjects who received only standard of care (SOC) (surgery plus radiotherapy). The Company is pursuing marketing approval for Multikine in the treatment of head and neck cancer in the U.S., Canada and the European Union.

About CEL-SCI Corporation

CEL-SCI believes that boosting a patient’s immune system while it is still intact should provide the greatest possible impact on survival. Therefore, in the Phase 3 study, CEL-SCI studied patients who were newly diagnosed with locally advanced primary squamous cell carcinoma of the head and neck with the investigational product Multikine first, BEFORE they received surgery and radiotherapy or surgery plus concurrent radiotherapy and chemotherapy (the current standard of care for these patients). This approach is unique. Most other cancer immunotherapies are administered only after conventional therapies have been tried and/or failed. Multikine (Leukocyte Interleukin, Injection) received Orphan Drug designation from the FDA for neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck. CEL-SCI believes that this Phase 3 study is the largest Phase 3 study in the world for the treatment of locally advanced primary head and neck cancer.

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. The Phase 3 study was started in early 2011 and was fully enrolled with 928 patients in September 2016 and concluded in December 2020. To test for an overall survival benefit, the study required CEL-SCI to wait until at least 298 (deaths) events had occurred among the two main comparator groups.

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