Abstract: The present invention relates to antibodies having specificity to HER4 and uses thereof, which are able to induce biased 4ICD routing/signaling. The inventors have isolated by antibody phage display three fully human anti-HER4 single-chain variable antibody fragment (scFv), selected on human HER4 extracellular domain, referred as C6 mAb, D5 mAb and F4 mAb and one fully human anti-HER4 scFv named H2 mAb, selected on NRG 1?1-stimulated EGFR/HER4 JMaCYT1-transfected NIH3T3 cells. In particular, the present invention relates to an isolated anti-HER4 antibody, wherein said antibody binds to an epitope of the HER4 protein.

Abstract: The present disclosure relates to bispecific antibodies targeting EGFR and HER2, and methods for the production of these antibodies. The bispecific antibodies consist of one complete antibody on which two VH-VL chains are attached via a linker to each NH terminal region of both VH chains of the antibody. The bispecific antibodies constructed use the amino acid sequences of the heavy chain (VH) and the light chain (VL) variable regions of two monoclonal antibodies targeting EGFR and HER2, namely cetuximab and trastuzumab, respectively.

Abstract: In ovarian carcinoma, Müllerian Inhibiting Substance (MIS) type II receptor (MISRII) and the MIS/MISRII signaling pathway are potential therapeutic targets. Conversely, the role of the three MIS type I receptors (MISRI; ALK2, ALK3 and ALK6) in this cancer needs to be clarified. Using four ovarian cancer cell lines and ovarian cancer cells isolated from patients' tumor ascites, the inventors found that ALK2 and ALK3 are the two main MISRIs involved in MIS signaling at low and high MIS concentrations, respectively. Moreover, high MIS concentrations were associated with apoptosis and decreased clonogenic survival, whereas low MIS concentrations improved cancer cell viability. Finally, the inventors showed that MIS siRNA inhibited MIS pro-survival effect. These last results open the way to an innovative therapeutic approach to suppress MIS proliferative effect, instead of administering high doses of MIS to induce cancer cell apoptosis.

Abstract: The invention relates to the combined use of anti-EGFR antibodies and anti-Her2 antibodies for the treatment of cancer, especially suitable for cancer expressing high levels of the EGFR type and low levels of HER2. The invention refers in particular monoclonal antibody “trastuzumab” (HERCEPTIN®) directed against the HER2 receptors the efficacy of which can be significantly increased in vivo when combined with monoclonal antibody “matuzumab” (hmAB 425, EMD 72000) directed against EGF receptors. The combination treatment is suitable for patients suffering from cancer having said receptor profile, preferably pancreatic cancer.
