Cantargia AB today announced that the IND application regarding the antibody CAN04 has been approved by the US FDA. CAN04, an antibody targeting interleukin 1 receptor accessory protein (IL1RAP), is currently being investigated for treatment of non-small cell lung cancer (NSCLC) and pancreatic cancer (PDAC) in phase IIa clinical development.

7 Jun 2018 The company is developing humanised, monoclonal antibody (CAN04) against IL1RAP, expecting to induce ADCC in the cancer cells.

Although conventional cancer therapeutic strategies, such as chemotherapy, radiation and surgery, have improved survival in patients with localized EWS tumours, they are ineffective for patients with metastatic disease. This subsequent new element, IL1RAP, became the focus of potential novel therapeutic strategies against cancer disease. But within the large family of cancers (more than 200 different members), Myeloid Leukemia (AML & CML) diseases show specificity. A specificity that turns out to be an obstacle to therapeutic treatment. 2. IL1RAP is expressed in a number of tumor tissues, including lung and pancreatic cancer, both on tumor cells and on infiltrating immune cells. We have, using antibodies directed against IL1RAP, shown the ability to target and kill IL1RAP-expressing tumor cells by ADCC, to inhibit IL-1 signaling in those cells and to reduce growth of transplanted human tumors in vivo.

Il1rap cancer

Background: Interleukin 1 receptor Accessory protein, IL1RAP, is expressed in several solid tumors, both on cancer cells and tumor-associated inflammatory cells. CAN04 is a first-in-class fully humanized monoclonal antibody targeting IL1RAP blocking IL-1 alpha and beta signaling and triggering antibody dependent cellular cytotoxicity.

Il1rap cancer

Chronic tumor IL-1 signaling is involved in resistance to cancer therapies, immune evasion, and metastases. Interleukin-1 receptor associated protein (IL1RAP) is a co-receptor of the IL-1 receptor (IL1R1) and the IL-33 receptor (ST2) and is required for signaling through both receptor complexes. We have previously described IL1RAP as a cancer target on leukemic cells and shown that antibodies directed against Interleukin-1 receptor associated protein (IL1RAP) is a co-receptor of the IL-1 receptor (IL1R1) and is required for IL-1 signaling.

Interleukin-1 receptor accessory protein is a protein that in humans is encoded by the IL1RAP gene. Interleukin 1 induces synthesis of acute phase and proinflammatory proteins during infection, tissue damage, or stress, by forming a complex at the cell membrane with an interleukin 1 receptor and an accessory protein. This gene encodes an interleukin 1 receptor accessory protein. Alternative splicing of this gene results in two transcript variants encoding two different isoforms
