argenx SE is to take back rights to the antibody therapeutic cusatuzumab after its partner Cilag GmbH International, one of the Janssen Pharmaceutical Companies of Johnson & Johnson Inc, announced plans to quit the three-year-old collaboration. Cusatuzumab is in a Phase 1b study in newly-diagnosed, elderly patients with acute myeloid leukaemia (AML). It is being tested with venetoclax and the chemotherapy azacitidine.
