Patent number: 12060360Abstract: This invention relates to compounds useful as lysyl oxidase (LOX) and lysyl oxidase-like (LOXL) family member (LOXL1, LOXL2, LOXL3, LOXL4) inhibitors. In addition there are contemplated pharmaceutical compositions comprising the compounds and the use of the compounds in the treatment of conditions mediated by LOX and LOXL, for example cancer. In particular a LOX inhibitor such as the present compounds may be for use in the treatment of a cancer associated with EGFR. The present invention also contemplates the identification of biomarkers that predict responsiveness to a LOX inhibitor.Type: GrantFiled: April 4, 2022Date of Patent: August 13, 2024Assignee: The Institute of Cancer Research: Royal Cancer HospitalInventors: Richard Marais, Caroline Springer, Dan Niculescu-Duvaz, Natalie Miller, Mohammed Aljarah, Alfonso Zambon, Leo Leung, Deborah Smithen, Michael Brown, Haoran Tang
