Combined Therapeutics to Present its Next-Generation mRNA-Based Vaccine Platform at the World Vaccine Congress 2023

BOSTON, March 30, 2023 /PRNewswire/ -- Combined Therapeutics Inc. (CTx), a privately held biotechnology company developing the next generation of mRNA therapeutics with a novel modified-mRNA platform to treat and prevent infectious diseases and cancer, today announced its participation in the upcoming World Vaccine Congress 2023, taking place in Washington, D.C., April 4-6, where it will present its cutting-edge mRNA-based vaccine technology MOPCTx in a poster presentation and oral communication.

"We are eagerly anticipating showcasing our MOPCTx platform at the World Vaccine Congress 2023 and sharing our latest findings with the world leaders in vaccine technology," said Lauren Speciner, Ph.D., Associate Director of Formulation and Process Development at Combined Therapeutics. "In animal studies, our platform has demonstrated a significant reduction in protein expression in several key organs after intramuscular administration while maintaining expression at the site of injection."

The MOPCTx platform, comprised of a modified mRNA encapsulated in a lipid nanoparticle, can code for a viral or bacterial antigen or a molecular adjuvant. The modifications enable targeted expression of these proteins in selected tissues, such as the site of injection. This leads to improved biodistribution over existing mRNA-based vaccine technologies while maintaining strong immunogenicity. Our platform reduces antigen protein expression ~90% or more in key vital organs such as the liver, kidneys, and heart while still maintaining expression at the site of injection.  Our SARS-CoV-2 MOPCTx vaccine shows strong immunogenicity and protection in hamsters from COVID-19 challenge. Moreover, Combined Therapeutics' approach involves co-administering IL-12 mRNA with an antigen to enhance the immune system response, also known as molecular adjuvantation.

World Vaccine Congress brings together leading experts and researchers in the field of vaccines to share the latest scientific advancements and trends in the development of new vaccines and therapies. Dr. Speciner, a distinguished researcher and expert in the field of mRNA-based vaccines, will be presenting the latest preclinical research findings and advancements of the MOPCTx platform, including lowering the vaccine dose needed for both monovalent and multivalent vaccines, strengthening and extending vaccine durability, improving efficacy animal models mimicking vulnerable populations, enhancing cell-mediated immunity, and restricting the expression of the cytokine to targeted tissues.

The affiliations in the oral communication include Boston Children's Hospital and Harvard Medical School, underscoring the advantageous collaboration between academia and industry to advance innovative solutions for unmet medical needs.

"We are thrilled to unveil the results of our collaborative efforts, leveraging the exceptional research capabilities of Combined Therapeutics, alongside the expertise of Boston Children's Hospital and Harvard Medical School. With this partnership, we are confident in our ability to achieve remarkable progress in advancing novel mRNA solutions to the clinic," said Dr. David Dowling, faculty member at Harvard Medical School.
