Lrrk2 degrader discovery: a high throughput direct-to-biology screening platform (Neuroscience 2025) - "Notably, ARV-102, a selective LRRK2 degrader developed by Arvinas, crosses the blood-brain barrier (BBB) and induces degradation of LRRK2 in the cerebral cortex following a single oral dose in mice carrying the G2019S LRRK2 mutation...In conclusion, D2B platform enables rapid synthesis and evaluation of PROTACs, demonstrating its utility in LRRK2 degrader discovery. The approach is scalable, efficient, and adaptable to other neurodegenerative disease targets, such as mutant huntingtin (mHTT) and GSK-3β, broadening its potential impact in CNS drug discovery."

Parkinson’s therapy ARV-102 able to reach brain, where needed: Study (Parkinson's News Today) - "In the volunteers taking part in the Phase 1 study, once-daily dosing with ARV-102 reduced biomarkers of damaged lysosomes, which are the structures that break down waste products — such as the misfolded alpha-synuclein protein that is a hallmark of Parkinson’s — in the body. The experimental therapy also reduced the inflammatory status of microglia, the brain’s resident immune cells."

First-in-Human Study to Assess the Safety, Pharmacokinetics, and Pharmacodynamics of Single and Multiple Ascending Doses of ARV-102, a PROTAC LRRK2 Degrader, in Healthy Participants (MDS Congress 2025) - "At single (10–200 mg) and multiple (10–80 mg) doses, ARV-102 was well tolerated, orally bioavailable, and CNS-penetrant, and achieved substantial peripheral and central LRRK2 degradation and pathway engagement in healthy participants. Based on these findings, a phase 1 SAD/MAD study of ARV-102 was initiated in patients with Parkinson's disease."

First Clinical Trials of ARV-102, a PROTAC LRRK2 Degrader: Characterization of Pathway Engagement in Healthy Volunteers and Patients With Parkinson's Disease (MDS Congress 2025) - "Proteomic analyses using CSF from HVs treated with 80-mg doses of ARV-102 daily for 14 days (n=9) showed decreases (mean % of baseline) in lysosomal (78.5% cathepsin H, 71.4% GPNMB, and 78.5% granulin) and microglial (85.9% C1QTNF1, 84.8% ENTPD1, and 46.8% CD68) pathway markers known to be elevated in LRRK2 Parkinson's disease, indicating ARV-102 regulates pathways linking LRRK2 to neurodegenerative disease. In the phase 1 study, 19 pts with Parkinson's disease received a single dose of ARV-102 or placebo (50-mg cohort: n=12; 200-mg cohort: n=7). Median reductions in LRRK2 protein levels from baseline in PBMCs were -86% in the 50-mg cohort and -97% in the 200-mg cohort, consistent with dose-dependent peripheral LRRK2 degradation seen in HVs."
