PCI Biotech

US patent for the vaccine technology (fimaVacc) with a new important class of adjuvants - Seite 2

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 fimaVacc across a wide range of doses. The immune results provided proof-of-concept and demonstrates fimaVacc‘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, and is also important for vaccination against some viral and parasitic infections, 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 fimaVacc technology has the potential to effectively enhance vaccine presentation through these pathways.

About PCI Biotech         
PCI Biotech is a biopharmaceutical late stage clinical development company focusing on development and commercialisation of novel therapies for the treatment of cancer through its innovative photochemical internalisation (PCI) technology platform.  PCI is applied to three distinct anticancer paradigms: fimaChem (enhancement of chemotherapeutics for localised treatment of cancer), fimaVacc (T-cell induction technology for therapeutic vaccination), and fimaNAc (nucleic acid therapeutics delivery).

Photochemical internalisation induces triggered endosomal release that is used to unlock the true potential of a wide array of therapeutic modalities. The company’s lead programme fimaChem consists of a pivotal study in bile duct cancer, an orphan indication with a high unmet need and without approved products. fimaVacc applies a unique mode of action to enhance the essential cytotoxic effect of therapeutic cancer vaccines, which works in synergy with several other state-of-the-art vaccination technologies. fimaNAc utilises the endosomal release to provide intracellular delivery of nucleic acids, such as mRNA and RNAi therapeutics, thereby addressing one of the major bottlenecks facing this emerging and promising field.
