Publication number: 20140308294Abstract: The invention relates to polypeptides that block or inhibit the interleukin-1 receptor 1 (IL-1R1), the interaction of IL-1beta with IL-1R1 or the interaction between IL-1R1 and interleukin-1 receptor accessory protein (IL-1RaCP). The invention relates specifically to therapeutic polypeptides that target specifically IL-1R1 present on tumor cells, cancer stem cells, and cancer stem cells which are resistant to chemotherapy or radiotherapy. The invention specifically relates to cancer stem cells (CSC) that express IL-1R1 to which said inhibitors bind. Finally the invention relates to a combination therapy comprising killing tumorigenic differentiating cancer cells by means of standard chemo- or radiotherapy and prior or subsequent to that applying IL-1R1 inhibitors which target specifically CSC and strip the tumor of its capacity to generate cancer cell progeny.Type: ApplicationFiled: April 13, 2012Publication date: October 16, 2014Applicant: MERCK PATENT GMBHInventors: Anita Seshire, Michael Wolf, Robert Tighe, Helen Sabzevari
