Company Background

Arvinas was established in 2013 with the ambitious goal of addressing diseases that have failed to respond to conventional therapeutic interventions. The company has its headquarters in New Haven, Connecticut, and has continuously expanded its research scope by investing in next-generation modalities. Leveraging discoveries from academic research—particularly the work emerging from Yale University—the company has evolved into a critical player that bridges basic science with clinical applications. Its background is characterized by the formation of a strong scientific and operational foundation, enabled by a relentless pursuit of innovation within the realm of targeted protein degradation.

Mission and Vision

Arvinas’ mission is centered on developing novel therapies that degrade disease-causing proteins, thereby offering groundbreaking therapeutic alternatives for patients suffering from life-threatening and debilitating diseases. The company’s vision is to democratize access to innovative treatments by addressing previously “undruggable” targets through the unique mechanism of action provided by proteolysis-targeting chimeras (PROTACs). Their goal is not only to provide effective treatments but also to fundamentally alter the drug development paradigm by shifting from traditional inhibition-based approaches to those that induce the selective degradation of pathogenic proteins.

Key Research Areas

Arvinas is primarily focused on the exploration and development of targeted therapies utilizing the principles of protein degradation. Their research is structured around several interrelated key areas: targeted protein degradation itself, oncology projects, and neurodegenerative disease programs. These areas are underpinned by a consistent commitment to innovative science, rigorous preclinical exploration, and clinical advancement.

Targeted Protein Degradation

At the heart of Arvinas’ approach is the concept of targeted protein degradation. This area represents both the company’s foundational technology and the strategic conduit through which it is expanding therapeutic possibilities. The PROTAC® Discovery Engine platform employed by Arvinas is engineered to harness the body’s natural protein disposal system—the ubiquitin–proteasome system—to selectively degrade disease-causing targets.

- Mechanism and Innovation:
The targeted protein degradation mechanism involves the design of bifunctional small molecules, known as PROTACs, that bind simultaneously to both a target protein and an E3 ubiquitin ligase. This dual-binding induces ubiquitination and eventual degradation of the target protein. This mechanism provides a catalytic, rather than stoichiometric, approach to therapy, meaning that lower doses may be effective and degradation of the protein can be sustained over time.

- Advantages Over Traditional Inhibitors:
The degradation approach circumvents a major limitation of traditional occupancy-based inhibitors which need to maintain continued binding to the target. By removing the target entirely, PROTACs can mitigate issues with drug resistance and offer a route to address proteins previously considered “undruggable” due to the absence of defined binding pockets.

- Preclinical and Clinical Validations:
Arvinas has demonstrated through robust preclinical pipelines that its PROTACs effectively degrade proteins in models of cancer and other diseases, thereby laying the groundwork for their progression into clinical trials. The success of ARV-110 (targeting the androgen receptor) and ARV-471 (targeting the estrogen receptor) exemplifies the potential of PROTAC technologies to offer rapid and sustained therapeutic benefits.

Oncology Projects

The oncology portfolio at Arvinas is one of the most advanced and diversified components of its research and development efforts. The primary focus in this area involves leveraging the targeted protein degradation platform to address cancers driven by specific, and sometimes resistant, protein targets.

- Prostate Cancer Initiatives:
Arvinas is aggressively pursuing programs aimed at treating metastatic castration-resistant prostate cancer (mCRPC). Their lead candidate, ARV-110, is a PROTAC designed to degrade the androgen receptor (AR), including both wild-type and mutant forms that may contribute to therapeutic resistance. Additionally, ARV-766 and bavdegalutamide represent complementary strategies for targeting AR-driven cancers, with ARV-766 specifically designed to overcome resistance mechanisms already observed with current AR inhibitors.

- Breast Cancer Therapeutics:
The company’s work in breast cancer focuses on vepdegestrant (formerly known as ARV-471), a protein degrader targeting the estrogen receptor (ER). ARV-471 is currently in clinical development phases for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer. The clinical programs include single-agent approaches as well as combination therapies with other agents such as CDK4/6 inhibitors, which are designed to enhance the therapeutic impact and delay progression.

- Clinical Trial Initiatives:
Arvinas has strategically structured various clinical trials to assess the safety, efficacy, and optimal dosing of its PROTAC candidates. The continued evaluation in Phase 1, Phase 2, and Phase 3 settings across multiple oncology indications underscores the broad applicability of the degradation technology in oncology. The integration of biomarker-driven patient selection into these trials further optimizes patient outcomes and accelerates the road to potential regulatory approvals.

- Addressing Drug Resistance:
Recognizing the challenge posed by resistance to existing therapies, Arvinas has emphasized the potential of its degraders to overcome these hurdles. For example, the preclinical models for ARV-766 have shown activity in resistant cancer models, thereby indicating its utility in cases where standard AR inhibitors like Xtandi or Zytiga fail to produce desired outcomes.

Neurodegenerative Disease Programs

In addition to oncology, Arvinas is pioneering research into therapies for neurodegenerative diseases. This area involves advancing novel PROTAC agents that are capable of crossing the blood-brain barrier and degrading proteins implicated in neurodegeneration.

- ARV-102 – A First-in-Class Candidate:
One of the cornerstone programs in the neurodegenerative space is ARV-102, which is designed as an oral PROTAC degrader for neurodegenerative disorders. ARV-102 targets leucine-rich repeat kinase 2 (LRRK2), a protein linked to the development and progression of diseases such as Parkinson’s disease and progressive supranuclear palsy. Preclinical data have shown that ARV-102 can achieve significant degradation levels of LRRK2 within deep-brain regions in non-human primates, hinting at substantial clinical promise.

- Capability to Cross the Blood-Brain Barrier:
A critical challenge in neurotherapeutics is the delivery of drugs to the brain. Arvinas’ developers have put significant emphasis on the optimization of its PROTAC molecules to cross the blood-brain barrier effectively. This feature distinguishes ARV-102 and potentially other future candidates as they seek to offer therapeutic benefits in central nervous system disorders where conventional drugs have limited penetration.

- Broader Implications for Neurodegenerative Therapy:
The development of ARV-102 represents a paradigm shift in the management of neurodegenerative diseases. Instead of merely inhibiting pathological proteins, the approach focuses on their active removal, thereby potentially providing a more sustained therapeutic impact. This strategy is underpinned by the firm scientific rationale that persistent degradation of disease-causing proteins can interrupt or even reverse deleterious neurodegenerative processes.
