U.S. Patent Office Issues CEL-SCI Two Patents for Its LEAPS Vaccine Platform Technology
- Patent #10,179,174 B2 titled “Method for inducing an immune response and formulations thereof” is focused on influenza
- Patent #10,179,164 B2 titled “Method for inducing an immune response for treatment of cancer and autoimmune diseases or conditions”
CEL-SCI’s LEAPS inventions relate to methods for diagnosing, preventing, and treating disease by generating or modulating the immune response through the use of specific peptides. LEAPS is a patented, T-cell modulation, peptide epitope delivery technology that enables CEL-SCI to design and synthesize proprietary peptide immunogens. LEAPS compounds consist of a small T-cell binding peptide ligand linked with a disease-associated peptide antigen.
The LEAPS platform technology is currently being developed as a therapeutic vaccine for rheumatoid arthritis (RA) under a $1.5 million grant from the U.S. National Institutes of Health (NIH). Upon completion of preclinical and Investigational New Drug (IND) enabling studies for the LEAPS-based rheumatoid arthritis vaccine candidate CEL-4000, CEL-SCI intends to file an IND application with the U.S. Food and Drug Administration.
“These patents will help provide the protection we need as development of our LEAPS candidates progress from preclinical to clinical studies and they strengthen our ability to attract potential partners to license this technology,” said Dr. Daniel Zimmerman, Senior Vice President of Research, Cellular Immunology.
This platform technology has been shown in several animal models to preferentially direct the immune response to a cellular (e.g. T-cell), humoral (antibody) or mixed pathway and has been shown to involve upregulation of T-regulatory (Treg) cells in some animal models. It has the potential to be utilized in diseases for which antigenic epitope sequences have already been identified, such as: a number of infectious diseases, some cancers, autoimmune diseases (e.g., RA), allergic asthma and allergy, and select CNS diseases (e.g., Alzheimer's).
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 treats patients who are newly diagnosed with advanced primary squamous cell carcinoma of the head and neck with Multikine first, BEFORE they receive surgery, radiation and/or chemotherapy. This approach is unique. Most other cancer immunotherapies are administered only after conventional therapies have been tried and/or failed. Multikine* (Leukocyte Interleukin, Injection), has received Orphan Drug designation from the FDA for the neoadjuvant therapy in patients with squamous cell carcinoma (cancer) of the head and neck.
CEL-SCI's Phase 3 study is the largest Phase 3 study in the world for the treatment of head and neck cancer. Per the study's protocol, newly diagnosed patients with advanced primary squamous cell carcinoma are treated with the Multikine treatment regimen for 3 weeks prior to the Standard of Care (SOC) which involves surgery, chemotherapy and/or radiation. Multikine is designed to help the immune system "see" the tumor at a time when the immune system is still relatively intact and thereby better able to mount an attack on the tumor. The aim of treatment with Multikine is to boost the body's immune system prior to SOC.
The Company's LEAPS technology is currently being developed as a therapeutic vaccine for rheumatoid arthritis and is supported by grants from the National Institutes of Health. The Company has operations in Vienna, Virginia, and in/near Baltimore, Maryland.
This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

Such statements include, but are not limited to, statements about the terms, expected proceeds, use of proceeds and closing of the offering. Factors that could cause or contribute to such differences include, an inability to duplicate the clinical results demonstrated in clinical studies, timely development of any potential products that can be shown to be safe and effective, receiving necessary regulatory approvals, difficulties in manufacturing any of the Company's potential products, inability to raise the necessary capital and the risk factors set forth from time to time in CEL-SCI's filings with the Securities and Exchange Commission, including but not limited to its report on Form 10-K for the year ended September 30, 2018. The Company undertakes no obligation to publicly release the result of any revision to these forward-looking statements which may be made to reflect the events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
* Multikine (Leukocyte Interleukin, Injection) is the trademark that CEL-SCI has registered for this investigational therapy, and this proprietary name is subject to FDA review in connection with the Company's future anticipated regulatory submission for approval. Multikine has not been licensed or approved for sale, barter or exchange by the FDA or any other regulatory agency. Similarly, its safety or efficacy has not been established for any use. Moreover, no definitive conclusions can be drawn from the early-phase, clinical-trials data involving the investigational therapy Multikine. Further research is required, and early-phase clinical trial results must be confirmed in the Phase 3 clinical trial of this investigational therapy that is in progress.
