CEL-SCI Corporation (NYSE MKT:CVM) (“CEL SCI” or the “Company”) today announced that Spain’s Agency for Medicinal Products and Medicinal Devices has authorized the Company to commence patient enrollment for its ongoing Phase 3 trial of its investigational immunotherapy Multikine* (Leukocyte Interleukin, Injection) in patients with advanced primary squamous cell carcinoma of the oral cavity/soft palate, a type of head and neck cancer. Spain is the 22nd country to authorize CEL-SCI’s Phase 3 trial for patient enrollment.

CEL-SCI recently announced it had reached a key milestone of receiving authorization to conduct the Phase 3 study from 21 countries, as originally planned. The Company is aiming to expand the trial into a total of approximately 100 clinical centers in about 25 countries. As of April 30, 2015, 437 patients had been enrolled in the global Phase 3 study.

About the Multikine Phase 3 Study

The Multikine Phase 3 study is enrolling patients with advanced primary squamous cell carcinoma of the head and neck. The objective of the study is to demonstrate a statistically significant improvement in the overall survival of enrolled patients who are treated with the Multikine treatment regimen plus standard of care (“SOC”) vs. subjects who are treated with SOC only.

About Multikine

Multikine (Leukocyte Interleukin, Injection) is an investigational immunotherapeutic agent that is being tested in an open-label, randomized, controlled, global pivotal Phase 3 clinical trial as a potential first-line treatment for advanced primary squamous cell carcinoma of the head and neck. Multikine is designed to be a different type of therapy in the fight against cancer: one that appears to have the potential to work with the body’s natural immune system in the fight against tumors.

Multikine is also being tested in a Phase 1 study under a Cooperative Research and Development Agreement (“CRADA”) with the U.S. Naval Medical Center, San Diego, as a potential treatment for peri-anal warts in HIV/HPV co-infected men and women. CEL-SCI has also entered into two co-development agreements with Ergomed Clinical Research Limited to further the development of Multikine for cervical dysplasia/neoplasia in women who are co-infected with HIV and HPV and for peri-anal warts in men and women who are co-infected with HIV and HPV.

About CEL-SCI Corporation

CEL-SCI’s work is focused on finding the best way to activate the immune system to fight cancer and infectious diseases. Its lead investigational therapy, Multikine (Leukocyte Interleukin, Injection), is currently being studied in a pivotal Phase 3 clinical trial as a potential neoadjuvant treatment for patients with squamous cell carcinoma of the head and neck. If the study endpoint, which is a 10% improvement in overall survival of the subjects treated with the Multikine treatment regimen plus the current SOC as compared to subjects treated with the current SOC only, is satisfied, the study results will be used to support applications that the Company plans to submit to regulatory agencies in order to seek commercial marketing approvals for Multikine in major markets around the world. Additional clinical indications for Multikine that are being investigated include the treatment of cervical dysplasia in HIV/HPV co-infected women, and the treatment of peri-anal warts in HIV/HPV co-infected men and women. A Phase 1 trial of the former indication has been completed at the University of Maryland. The latter indication is now in a Phase 1 trial in conjunction with the U.S. Naval Medical Center, San Diego, under a CRADA.

CEL-SCI is also developing its pre-clinical L.E.A.P.S. (Ligand Epitope Antigen Presentation System) technology for the potential treatment of pandemic influenza in hospitalized patients and as a potential vaccine for the treatment of rheumatoid arthritis.

The Company has operations in Vienna, Virginia, and in/near Baltimore, Maryland. For more information, please visit www.cel-sci.com.
