The Nuclisome concept builds on a novel two-step targeting strategy with the aim to deliver short-range Auger-electron-emitting radionuclides to nuclear DNA of tumor cells. The concept is based on the use of Nuclisome-particles, i.e., tumor-targeted PEG-stabilized liposomes loaded with a unique DNA-intercalating compound that enables specific and effective delivery of radionuclides to DNA. The specific and potent two-step targeting leads to eradication of tumor cells while toxicity to normal organs is reduced to a minimum. Results of in vitro and in vivo studies point towards the Nuclisome concept as a promising strategy for the treatment of small tumor masses and, in particular, for the elimination of spread single cells and micrometastases.
