Mutations in Leucine-Rich Repeat Kinase 2 (LRRK2) are the most common genetic cause of Parkinson’s disease, leading to the development of LRRK2 inhibitors as potential therapeutic approach. Among them, Compound A has recently been selected as a potent, selective and brain-penetrant LRRK2 inhibitor. In order to confirm its in vivo target engagement and equipotency on wild type and G2019S LRRK2 mutants, several Pharmacokinetic/Pharmacodynamic (PK/PD) studies were performed in rodent and non-rodent species.
