Jeg synes det er mer og mer som vitner om at PCIB sin fimaVacc teknologi (spesielt med T Cell egenskaper i fase 1 studiet) er hyperaktuell som teknologi i nær fremtid for vaksinasjonsprogrammer!

fimaVACC – An innovative proprietary T-cell induction technology based on PCI
Effective induction of CD8 T-cells is key to realize the huge potential of therapeutic cancer vaccination, but this has been difficult to achieve with today’s vaccination technologies. The fimaVACC technology may provide a solution to this problem, thereby substantially improving the potential to trigger the immune system to fight both cancers and infectious diseases.
Mechanism of action:
• Induction of CD8 T-cells is essential for the generation of an immunological response that can attack the tumour cells. Induction of CD8 T-cells is typically mediated through MHC Class I antigen presentation by antigen presenting cells (APCs).
• The PCI technology can re-localise endocytosed antigens from endosomes to the cytosol in APCs, thereby making the antigens accessible for the MHC Class I presentation machinery.
Clinical Proof of Concept for fima VACC :
Successful clinical translation of fima VACC and proof-of-concept by a phase I study in healthy volunteers were reported early May 2019 (link to press release)
The results show that tolerable treatments with the fima VACC technology in combination with a state of the art adjuvant (Hiltonol) provides substantial increase in the number of T-cell responders already after two vaccinations and a clear enhancement in the magnitude of T-cell responses compared to the control group with the adjuvant Hiltonol. The important CD8 responses are more robust and exhibit increased functionality. The results are with HPV E7, an antigen known to be notoriously difficult to induce CD8 T-cell responses for in man.
PCI Biotech’s vaccination technology platform, fima VACC , is mainly directed at enhancing CD8 T-cell responses to therapeutic and prophylactic vaccines. By releasing antigens (peptides and protein antigens) from endosomes, MHC Class I presentation is enhanced, strongly stimulating antigen specific CTL responses. In addition, fima VACC enhances helper T-cell and antibody responses.

…« 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.»
