Marks key achievement that is a prerequisite to filing a Biologics License Application with the FDA and other regulators for marketing approval

CEL-SCI Corporation (NYSE American: CVM) today reported that its Multikine^® (Leukocyte Interleukin, Injection)* cGMP state-of-the-art dedicated manufacturing facility commissioning has been completed.

“This is a very significant milestone in bringing Multikine to market since the manufacturing facility is part of a planned Biologics License Application required for approval of Multikine in the treatment of head and neck cancer,” stated CEL-SCI’s CEO Geert Kersten.

“The high degree of complexity involved in manufacturing Multikine has required tremendous investment and time on CEL-SCI's part. Our manufacturing trade secret, capability, and know-how are high-value key strategic assets that would be very difficult for others to replicate. This achievement marks a very big step towards the preparation of Multikine for marketing approval,” Kersten added.

Originally constructed to supply Multikine for the world’s largest global pivotal Phase 3 trial in locally advanced squamous cell carcinoma of the head and neck, CEL-SCI’s facility has been expanded and upgraded in preparation for the Company’s submission of Multikine for regulatory approval and commercial scale manufacturing. In keeping with CEL-SCI Validation Master Plan, industry standards, International Society for Pharmaceutical Engineering (ISPE) guidelines, International Conference for Harmonization (ICH), and in compliance with regulatory guidelines, CEL-SCI undertook commissioning and qualifying the facility’s utilities, systems, and equipment.

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. 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. In a Phase 3 study, CEL-SCI studied patients who were newly diagnosed with locally advanced primary squamous cell carcinoma of the head and neck (oral cavity and soft-palate) with the investigational product Multikine administered first, before they received the standard of care, which involved surgery followed by either radiation or chemoradiation. The Phase 3 study enrolled 928 patients. Our approach is unique because most other cancer immunotherapies are administered only after conventional therapies have been tried and/or failed.

After analyzing data from the Phase 3 study, we have better defined the target population, which is advanced primary head and neck cancer patients with no lymph node involvement and with low PD-L1 tumor expression. In the Phase 3 study, we observed statistically significant survival data in the final target population, showing that Multikine cut the risk of death in half at five years vs control. We plan to submit the proposed study protocol to the FDA in Q1 2024, with the goal to get FDA buy-in for a confirmatory clinical trial, and also to discuss potential accelerated approval pathways.

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.

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