VIENNA, Va.--(BUSINESS WIRE)--CEL-SCI Corporation (NYSE MKT:CVM) today announced that Daniel Zimmerman, Ph.D., Senior Vice President of Research, Cellular Immunology, presented additional data on its LEAPS rheumatoid arthritis (RA) vaccine candidates CEL-4000 and CEL-2000 at IMMUNOLOGY 2017, the annual meeting of the American Association of Immunologists (AAI), May 12 – 16 in Washington, D.C.
The title of his poster is “Key serum cytokine markers for evaluating the efficacy of vaccine therapy in autoimmune models of rheumatoid arthritis.” The abstract can be viewed online or found through the conference website at: www.immunology2017.org.
Dr. Zimmerman and the research team concluded that serum concentrations and ratios of key disease-related cytokines can predict therapeutic efficacy in different animal models of RA. The data showed that a reduced RA disease progression was observed in mice treated with LEAPS vaccines and was accompanied by decreased pro-inflammatory cytokines level and increased ratios of anti-inflammatory/regulatory to pro-inflammatory cytokines. Thus, a successful vaccine therapy appears to be associated with a ratio shift in favor of anti-inflammatory/regulatory cytokines. The ability to predict cytokine responses to therapy should allow for better design or choice of the appropriate immunomodulatory LEAPS vaccines and other therapies in RA.
L.E.A.P.S. (Ligand Epitope Antigen Presentation System) is a CEL-SCI patented platform technology designed to stimulate antigen-specific immune responses in T-cells using synthetic peptides. LEAPS constructs physically link the antigenic peptide with a T-cell binding ligand and are delivered directly to the recipient by injection or through absorption onto mucosal surfaces, potentially enhancing T-cell responses to a particular antigen.
CEL-SCI's work is focused on finding the best way to activate the immune system to fight cancer and infectious diseases. The Company has operations in Vienna, Virginia, and in/near Baltimore, Maryland.
