A nucleic acid sequence encoding said antibody, a vector comprising the nucleic acid sequence, a host cell comprising said nucleic acid sequence or vector, an immunoconjugate comprising the said antibody, a pharmaceutical composition comprising the said antibody or immunoconjugate, and the use as a drug of the said antibody, cell or composition is also considered in the present invention.

Abstract: The present invention relates to a human AMHRII-binding agent for its use for preventing or treating a lung cancer, and especially a non-small call lung cancer (NSCLC), and even more especially a NSCLC selected in a group comprising epidermoid NSCLC, adenocarcinoma NSCLC, large cells NSCLC and squamous cell carcinoma NSCLC and neuroendocrine NSCLC.

Abstract: The present invention relates to an antibody drug conjugate (ADC) of general formula (I) (D-Lk1-C(O)-Lk2-C2H4—NH-Lk3)n-Ab. A pharmaceutical composition comprising, in a pharmaceutically acceptable medium, the said ADC is also concerned by the present invention, as well as the use of this ADC or composition as a medicament, and in particular in the prevention and/or the treatment of an anti-Müllerian hormone type II receptor (AMHRII) expressing cancer in an individual.

Abstract: The present invention relates to a human AMHRII-binding agent for its use for preventing or treating a cancer selected in a group of cancers comprising colon cancer, liver cancer, hepatocellular carcinoma, testis cancer, thyroid cancer, gastric cancer, gastrointestinal cancer, bladder cancer, pancreatic cancer, head and neck cancer, kidney cancer, liposarcoma, pleuramesothelioma, melanoma, sarcoma, brain cancer, osteocarcinoma and leukemia.

Abstract: The present disclosure relates to a neuregulin non competitive allosteric anti-human-HER3 antibody having a human constant region; and less than 65% of the glycan structures carried by the glycosylation site of the antibody comprises a fucose molecule. The antibody is characterized by its variable sequences.

Abstract: The present invention relates to a glyco-engineered Fc fragment-bearing compound for its use as an immunosuppression inhibitor in the treatment of a cancer-associated immunosuppression. The invention further relates to a pharmaceutical composition comprising at least this glyco-engineered Fc fragment-bearing compound.

Abstract: This invention relates to antibody drug conjugates (ADC), antibody conjugates (AC) and novel antibodies. Particularly, the ADC, AC and antibodies disclosed herein specifically bind to the human anti-Müllerian hormone type II receptor (AMHR-II) and can be used to treat and/or identify AMHR-II expressing cancers, such as prostate cancer, breast cancer and gynecologic cancers expressing AMHR-II, such as ovarian cancer, in particular metastatic ovarian cancer, serous cancer, hypernephroma, endometrioid, colloidal epithelium, prostate cancer, germ cell cancer, endometrial cancer, mixed Müllerian malignant tumor of the uterus, leiomyosarcoma, or endometrial stromal sarcoma.
