Immunicum AB and PCI Biotech Holding ASA announced an extension of their current collaboration. The companies jointly research the possibility to overcome current hurdles in cancer immunotherapy by introducing tumor independent immune targets into the tumor microenvironment, in combination with vaccination or adoptive immunotherapies. The so-called Tumor Independent Antigen concept, which has been invented by Immunicum, could benefit from PCI Biotech's antigen delivery technologies based on Photochemical Internalisation.

Following the encouraging results of the first set of in vitro experiments, during which the delivery protocol of the combination treatment has been optimized, the companies have decided to move ahead to evaluate the novel therapeutic concept in animal models. While the first experiments were conducted by Immunicum, this further in vivo evaluation will be carried out by PCI Biotech.
