Celsion Corporation announced the filing of a provisional U.S. patent application for a novel DNA-based, investigational vaccine for preventing or treating infections from a broad range of infectious agents including the coronavirus disease using its PLACCINE DNA vaccine technology platform. The provisional patent covers a family of novel composition of multi-cistronic vectors and polymeric nanoparticles that comprise the PLACCINE DNA vaccine platform technology for preventing or treating infectious agents that have the potential for global pandemics, including the SARS-CoV-2 virus and its variations, using the Company’s platform technology. PLACCINE is a natural extension of the Company’s synthetic, non-viral TheraPlas delivery technology currently in a Phase II trial for the treatment of late-stage ovarian cancer with GEN-1, Celsion’s DNA-mediated IL-12 immunotherapy. Celsion’s vaccine approach is designed to optimize the quality of the immune response dictating the efficiency of pathogen clearance and patient recovery. Celsion has taken a multivalent approach in an effort to generate an even more robust immune response that not only results in a strong neutralizing antibody response, but also a more robust and durable T-cell response. Delivered with Celsion’s synthetic polymeric system, the proprietary DNA plasmid is protected from degradation and its cellular uptake is facilitated. Celsion's proprietary multifunctional DNA vaccine technology concept is built on the flexible PLACCINE technology platform that is amenable to rapidly responding to the SARS-CoV-2 virus, as well as possible future mutations of SARS-CoV-2, other future pandemics, emerging bioterrorism threats, and novel infectious diseases. Celsion’s extensive experience with TheraPlas suggests that the PLACCINE-based nanoparticles are stable at storage temperatures of 4oC to 25oC, making vaccines developed on this platform easily suitable for broad world-wide distribution.
Imunon, Inc. is a clinical-stage biotechnology company. The Company is focused on advancing a portfolio of treatments that harness the bodyâs natural mechanisms across an array of human diseases. The Company is developing non-viral Deoxyribonucleic acid (DNA) technology across four modalities. The first modality, TheraPlas, is developed for the coding of proteins and cytokines in the treatment of solid tumors. The second modality, PlaCCine, is developed for the coding of viral antigens that can elicit a strong immunological response. The third modality, FixPlas, concerns the application of Imunonâs DNA technology to produce universal cancer vaccines, also called tumor associated antigen cancer vaccines. The fourth modality, IndiPlas, is in the discovery phase and is focused on the development of personalized cancer vaccines, or neoepitope cancer vaccines. Its lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer.
