Celsion Reports T-cell , B-cell Response from In Vivo Studies of DNA Vaccine Platform

 Results Indicate Induction of Adaptive Immune Response Against SARS-CoV-2

Company Plans Additional Development Work to Further Optimize its Vaccine Platform Through Vector Compositions, Delivery Route, Dosing and Dosing Frequency, and Use of Molecular Adjuvant

Celsion Corporation (NASDAQ: CLSN), a clinical-stage company focused on DNA-based immunotherapy and next-generation vaccines, today announced results from preclinical in vivo studies showing production of antibodies and cytotoxic T-cell response specific to the spike antigen of SARS-CoV-2 when immunizing BALB/c mice with the Company’s next-generation PLACCINE DNA vaccine platform. Moreover, the antibodies to SARS-CoV-2 spike antigen prevented the infection of cultured cells in a viral neutralization assay. The production of antibodies predicts the ability of PLACCINE to protect against SARS-CoV-2 exposure, and the elicitation of cytotoxic T-cell response shows the vaccine’s potential to eradicate cells infected with SARS-CoV-2.

These findings demonstrate the potential immunogenicity of Celsion’s PLACCINE DNA vaccine, which is intended to provide broad-spectrum protection and resistance against variants by incorporating multiple viral antigens, to improve vaccine stability at storage temperatures of 4o C and above, and to facilitate cheaper and easier manufacturing. Celsion expects to report these data at the International Vaccines Conference to be held on October 19 – 21, 2021.
