Item 7.01 Regulation FD Disclosure

On March 18, 2026, Arvinas, Inc. (the "Company") issued a press release announcing positive Phase 1 clinical trial data for ARV-102, an investigational, orally bioavailable PROteolysis TArgeting Chimera ("PROTAC") designed to cross the blood-brain barrier and specifically target and degrade leucine-rich repeat kinase 2 ("LRRK2"), showing greater than 50% LRRK2 degradation in the cerebrospinal fluid ("CSF") of patients with Parkinson’s disease treated for 28 days. Data from the single-center, randomized, double-blind, placebo-controlled, multiple dose ("MD") cohort of the Phase 1 clinical trial in patients with Parkinson's disease were shared in an oral presentation at the 2026 International Conference on Alzheimer’s and Parkinson’s Diseases and Related Neurological Disorders ("AD/PD™ 2026") in Copenhagen, Denmark.

The full text of the press release issued in connection with the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated into this Item 7.01 by reference.

The information in this Item 7.01, including Exhibit 99.1 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 8.01 Other Events.

On March 18, 2026, the Company issued a press release announcing positive Phase 1 clinical trial data for ARV-102, an investigational, orally bioavailable PROTAC designed to cross the blood-brain barrier and specifically target and degrade LRRK, showing greater than 50% LRRK2 degradation in the CSF of patients with Parkinson’s disease treated for 28 days.

The ARV-102 Phase 1 clinical trial is designed to assess the safety, pharmacokinetics, and pharmacodynamics of orally administered ARV-102 in patients with Parkinson's disease. Data from the single-center, randomized, double-blind, placebo-controlled, MD cohort of the Phase 1 clinical trial in patients with Parkinson's disease were shared in an oral presentation at AD/PD™ 2026 in Copenhagen, Denmark. In the MD cohort, patients were randomized to either placebo or multiple oral doses of ARV-102 (20 mg, 40 mg, or 80 mg) for 28 days with follow-up at day 42.

Data presented from the clinical trial included the following:

Safety Profile

•Multiple oral doses of ARV-102 (20 mg, 40 mg, or 80 mg once daily for 28 days) were well tolerated in participants with Parkinson's disease.

•All treatment-emergent adverse events and treatment-related adverse events were mild in severity, with no serious adverse events, discontinuations, or deaths reported.

•No significant changes in lung functions or respiratory symptoms were observed during the 28 days of treatment or during follow-up.

Pharmacokinetic and Pharmacodynamic Evaluation

•ARV-102 levels in CSF increased in a dose-dependent manner after multiple doses, indicating brain penetration.

•The area under the concentration-time curve (AUC0-24) and the maximum plasma concentration (Cmax) after daily dosing increased with dose with a mean terminal plasma half-life (t1/2) of 68 hours.

•ARV-102 achieved peripheral LRRK2 degradation and dose-dependent degradation of LRRK2 in CSF, with approximately 50% or greater degradation observed at all doses by day 14 and maintained through day 28.

•Endolysosomal and neuroinflammatory pathway proteins that are elevated in LRRK2-related Parkinson's disease (e.g., CD68, GPNMB) were reduced with ARV-102.

•Pharmacology and changes in peripheral biomarkers in patients with Parkinson's disease were consistent with observations in healthy volunteers dosed with ARV-102.

Based on the data, the Company plans to continue investigation of ARV-102 in neurodegenerative diseases associated with LRRK2 and endolysosomal dysfunction. Pending regulatory feedback, the Company intends to initiate a Phase 1b clinical

trial in progressive supranuclear palsy in the second quarter of 2026, with the potential to initiate a registrational trial in late 2026, while it continues to evaluate development options for ARV-102 in Parkinson’s disease.
