About fima Vacc This novel vaccine technology applies a unique mode of action, triggered endosomal release of antigens, to enhance the essential cytotoxic effect of therapeutic cancer vaccines and works in synergy with several other state-of-the-art vaccination technologies. The fima Vacc programme aims to enhance the cellular immune responses that are important for the therapeutic effect of vaccines, and the fima Vacc technology has proven excellent preclinical efficacy with protein- and peptide-based vaccines. The technology has shown particularly strong CD8 T-cell immune responses, which are important for therapeutic vaccination, as well as enhanced helper (CD4) T-cell and antibody responses.
PCI Biotech successfully translated the vaccination technology into humans through a Phase I study in healthy volunteers that was completed in May 2019. The study covered more than 90 subjects and established the tolerability of fima Vacc across a wide range of doses. The immune results provided proof-of-concept and demonstrates fima Vacc ‘s potential to enhance overall T-cell responses, by demonstrating improvement of the immunogenicity of vaccines in healthy volunteers.
Effective induction of cytotoxic T-cells will be critical to realise the huge potential of therapeutic cancer vaccines, but vaccines often fail to generate such responses. Insufficient delivery of vaccine antigens to the appropriate presentation pathway in the immune cells may be one of the main reasons for weak cytotoxic T-cell responses. The fima Vacc technology has the potential to effectively enhance vaccine presentation through these pathways.
PCI Biotech: US patent granted for the vaccine technology (fimaVACC) in combination with cytokines
Oslo (Norway), 21 January 2020 – PCI Biotech (OSE: PCIB), a cancer focused biopharmaceutical company, today announces that the U.S. Patent and Trademark Office (USPTO) has granted the company a US patent covering the use of fima Vacc in combination with cytokines.
