• Data demonstrate that ARV-102 was well tolerated, orally bioavailable, and brain-penetrant; ARV-102 achieved central and peripheral LRRK2 reduction indicating substantial LRRK2 protein degradation in healthy volunteers
• Findings support continued evaluation of ARV-102 in neurodegenerative diseases associated with LRRK2 dysfunction; a Phase 1 trial in patients with Parkinson's disease has been initiated and is currently enrolling

NEW HAVEN, Conn., April 04, 2025 (GLOBE NEWSWIRE) -- Arvinas, Inc. (Nasdaq: ARVN), a clinical-stage biotechnology company working to develop a new class of drugs based on targeted protein degradation, today presented data from the first-in-human clinical trial of ARV-102, the Company’s investigational PROteolysis TArgeting Chimera (PROTAC) leucine-rich repeat kinase 2 (LRRK2) degrader. In the trial, ARV-102 demonstrated substantial reduction of LRRK2, a multifunctional protein that has been implicated in Parkinson’s disease (PD) and progressive supranuclear palsy (PSP), in cerebral spinal fluid (CSF), with a promising safety/tolerability profile and favorable pharmacodynamic outcomes. Results from the randomized, double-blind, placebo-controlled single ascending dose (SAD) cohort of the Phase 1 healthy volunteer trial, and initial results from the multiple ascending dose (MAD) cohort, were shared in a presentation at the 2025 International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD™ 2025) in Vienna, Austria.

The SAD cohort evaluated ARV-102 doses ranging from 10 mg to 200 mg. The MAD cohort evaluated doses ranging from 10 mg to 80 mg. Key findings from the trial showed:

• ARV-102 was generally safe and well tolerated with no serious adverse events reported after single or multiple doses.
• ARV-102 exposure in the CSF increased in a dose-dependent manner after single and multiple doses, indicating brain penetration.
• At a single oral dose of at least 60 mg, and once daily repeated oral doses of at least 20 mg, ARV-102 achieved greater than 50% LRRK2 reduction in the CSF and greater than 90% LRRK2 reduction in the peripheral blood mononuclear cells (PBMCs), indicating substantial central and peripheral LRRK2 protein degradation.
• Inhibition of Rab10 phosphorylation in PBMCs and reduction of bis(monoacylglycerol)phosphate (BMP) in urine following single doses of ARV-102, signifying downstream LRRK2 pathway engagement.

ARV-102 is a novel investigational oral PROTAC designed to cross the blood-brain barrier and target LRRK2. While LRRK2 is primarily known for its role in PD, emerging evidence suggests that it also plays a role in tauopathies, including PSP, and that LRRK2 dysfunction may contribute to the development and progression of both diseases.

“The ability of ARV-102 to cross the blood-brain barrier and degrade the LRRK2 protein offers a potentially transformative therapeutic approach in the treatment of devastating neurodegenerative diseases,” said Noah Berkowitz, M.D., Ph.D., Chief Medical Officer at Arvinas. “We believe these results support continuing our ARV-102 clinical program and building upon our body of evidence for this lead PROTAC degrader candidate in our neuroscience pipeline.”

Data presented at AD/PD™ 2025

The ARV-102 Phase 1 study is designed to assess the safety, pharmacokinetics, and pharmacodynamics of orally administered ARV-102 in healthy male volunteers. This is a single-center, randomized, double-blind, placebo-controlled trial evaluating outcomes in both SAD and MAD cohorts. In the SAD cohort, volunteers were randomized 3:1 to either placebo or a single dose of ARV-102 (10 mg, 30 mg, 60 mg, 90 mg, 150 mg, or 200 mg) on day 1 with follow-up until day 10. In the MAD cohort, volunteers were randomized to either placebo or a once daily dose of ARV-102 (10 mg, 20 mg, 40 mg, or 80 mg) for 14 days with follow-up until day 28.

Safety Profile

• At the time of data cutoff (March 13, 2025), the SAD cohort of the Phase 1 clinical trial is completed and the MAD cohort is ongoing. Based on evaluation of the available data from single and multiple oral doses, ARV-102 was well tolerated in healthy volunteers.
• Of the 47 volunteers across all SAD dose levels, the primary treatment related adverse events were headache and fatigue. Headaches occurred in 17.1% (6/35) of treated individuals compared to 0% (0/12) in placebo controls. Fatigue occurred in 8.6% (3/35) of the treated individuals compared to 25% (3/12) in placebo controls.
• Procedural pain associated with the lumbar puncture occurred in 28.6% (10/35) of treated individuals compared to 41.7% (5/12) in placebo controls. Post lumbar puncture syndrome was only observed in the treated cohort, at a rate of 17.1% (6/35).
• No serious adverse events were reported in either the SAD or MAD cohorts.

ARV-102 Exposure in Plasma and CSF

• ARV-102 exhibited median maximum concentration (T_max) 6 hours after oral administration.
• The area under the concentration-time curve in the first 24 hours post dosing (AUC_0-24) and the maximum plasma concentration (C_max) increased in a dose-dependent manner and the median terminal plasma half-life (t_1/2) was 73 hours.
• ARV-102 levels in CSF increased in a dose dependent manner in both the SAD and MAD cohorts.

Pharmacodynamic Evaluation

• At single doses of greater than or equal to 60 mg and repeated doses of greater than or equal to 20 mg, LRRK2 reduction of greater than 90% in PBMCs was observed.
• ARV-102 at single doses of greater than or equal to 30 mg induced greater than 50% decreases in peripheral phospho-Rab10^T73, a LRRK2 substrate and biomarker for downstream LRRK2 activity; data for this endpoint in the MAD cohort is pending.
• ARV-102 at single doses of greater than or equal to 30 mg resulted in greater than 90% decrease of BMP in urine, a biomarker of lysosomal function; data for this endpoint in the MAD cohort is pending.
• In CSF, ARV-102 induced dose-dependent LRRK2 reduction, with greater than 50% LRRK2 reduction at single doses of greater than or equal to 60 mg and repeated doses of greater than or equal to 20 mg.

Arvinas believes these results support continued investigation of ARV-102 in neurodegenerative diseases associated with LRRK2 and lysosome dysfunction.

• In the fourth quarter of 2024, Arvinas initiated dosing in the SAD cohort of the Phase 1 clinical trial with ARV-102 in patients with PD (EUCT 2024-516888-84-00). The Company expects to complete enrollment and present initial data from the ongoing SAD cohort of the Phase 1 clinical trial in patients with PD and initiate the MAD cohort of the Phase 1 clinical trial in patients with PD, in 2025.
