• Denali Therapeutics has dosed the first participant in its Phase 2a BEACON study of BIIB122, a LRRK2 inhibitor, for LRRK2-associated Parkinson's disease.
• The BEACON study will assess the safety and biomarker effects of BIIB122 in approximately 50 participants with LRRK2-related Parkinson's.
• BIIB122 is also under investigation in the Phase 2b LUMA study for early-stage Parkinson's, with or without LRRK2 mutation, in collaboration with Biogen.
• LRRK2 inhibition targets lysosomal dysfunction, potentially modifying the course of Parkinson's disease rather than just treating symptoms.
