DNL151, DNL201, and BIIB094: experimental agents for the treatment of Parkinson's disease

Expert Opin Investig Drugs. 2023 Sep 27:1-6. doi: 10.1080/13543784.2023.2263357. Online ahead of print.ABSTRACTINTRODUCTION: Pathogenic mutations of the abundant leucine-rich repeat kinase 2 gene support the onset of familial and sporadic forms of Parkinson's disease. These genetic variants catalyze kinase activity by substrate phosphorylation. They promote the nigrostriatal neurodegenerative process, i.e. characterized by Lewy body formation.AREAS COVERED: This narrative review discusses leucine-rich repeat kinase 2 inhibitors as therapeutic concept for beneficial disease modification following a literature search.EXPERT OPINION: Leucine-rich repeat kinase 2 gene function contributes to the onset of microglia inflammation, cellular, and mitochondrial dysfunction. Leucine-rich repeat kinase 2 inhibition with oral application of DNL151, respectively DNL201, and intrathecal administration of the antisense oligonucleotide BIIB094 in a single and multiple ascending dose study was safe and well tolerated. Approval of Leucine-rich repeat kinase 2 inhibitors in case of positive clinical study outcomes will introduce personalized medicine for beneficial modification of progression as the most unmet need for treatment of patients with Parkinson's disease. In addition to the currently, preponderantly performed clinical rating with established scales, further clinical trial endpoints, such as dosing of dopamine substitution, may be considered in study designs to demonstrate therapeutic ...
