PCI Biotech Holding ASA, a biopharmaceutical company, focuses on the development and commercialization of novel therapies for the treatment of cancer through its photochemical internalization (PCI) technology platform. The company's technology platform consists of a proprietary small molecule photosensitiser (fimaporfin) and a light source; and develops photochemical internalisation (PCI), inducing light-triggered intracellular release for various therapeutic modalities, as well as photochemical lysis (PCL) comprising light-triggered cell lysis, which enhances yield and purity in viral vector manufacturing. It also explores for intratumoural immunotherapy therapeutics that identifies novel treatment combinations to overcome resistance to immune-checkpoint inhibitors and safety-issues associated with treatments; and develops nucleic acid therapeutics to improve the treatment of dermatological diseases. In addition, the company develops fimaVACC for immunotherapy indications, which is in pre-clinical study; fimaNAc, a nucleic acid therapeutics delivery technology, which is in pre-clinical study for bioprocessing and dermatology indications; and technology for viral vector manufacturing and pre-clinical research for intratumoural immunotherapy. PCI Biotech Holding ASA was incorporated in 2007 and is headquartered in Oslo, Norway.
