PCI Biotech file patents for combination of siRNA and the PCI technology

21 Mar 2007 - Photocure's daughter company PCI Biotech is developing a proprietary technology for site-specific drug delivery and drug enhancement called Photochemical Internalisation (PCI). PCI Biotech has, according to an agreement with Rikshospitalet-Radiumhospitalet HF, filed two patent applications covering the combination of siRNA (short interfering RNA) and the PCI technology. PCI Biotech plans to explore this field of the PCI-technology and will sponsor a dedicated research position within this field the next three years. Kjetil Hestdal, President and CEO of Photocure, says: "Achieving safe and efficient gene delivery in the body has been a major limiting factor in the development of gene therapy. Our goal is to develop an effective treatment of cancer therapy through the combination of siRNA and the PCI technology."
