Cardiac remodeling involves myocardial hypertrophy and fibrosis which impairs cardiac function and, ultimately, contributes to heart failure (HF) and mortality. Fibrosis largely develops due to excessive matrix deposition and lysyl oxidase(s)-dependent collagen cross-linking. In particular, lysyl oxidase-like 2 (LOXL2) has a critical role in disease progression, representing a promising therapeutic target and rationale for the development of novel, efficacious LOXL2 inhibitor(s). Herein, we describe the pre-clinical validation of a potent small molecule LOXL2 inhibitor as an anti-fibrotic agent, along with its clinical suitability, as high levels of target engagement were sustained in Phase 1 clinical trials while also being well tolerated. We show that LOXL2 concentration is increased in the plasma of patients with HF due to existing hypertension or aortic stenosis. Plasma LOXL2 concentration were correlated with the left ventricular mass index. A novel LOXL2 inhibitor, SNT-5382, was characterised, including in vitro and in vivo assessment of potency and mode of action, which showed beneficial drug-like properties. Preclinically, SNT-5382 reduced fibrosis and improved cardiac function in a myocardial infarction (MI) mouse model. Phase 1 clinical studies demonstrated a good safety and a PK profile capable of eliciting high and prolonged LOXL2 inhibition following repeated once daily oral dosing. Our findings underscore the pivotal role of LOXL2 in the development of HF. SNT-5382 exhibited potent anti-fibrotic efficacy in a MI model and sustained clinical target engagement.
