Exscientia Fires CEO for Inappropriate Relationships with Employees: Impact on Pharmaceutical Leadership


Exscientia has recently made significant leadership changes following the termination of its founder and former CEO, Andrew Hopkins, PhD. Hopkins was dismissed after the company’s board determined that he had inappropriate relationships with two employees, which went against the company’s values. This decision was announced in a regulatory filing and has had a noticeable impact on the company’s stock performance.

Leadership Changes

The company also saw the resignation of its chairman, David Nicholson. It was revealed that Nicholson had prior knowledge of Hopkins’ actions and chose to address the issue through outside counsel rather than bringing it to the board. Consequently, Exscientia appointed Dave Hallett, PhD, as the interim CEO and interim principal executive officer. Hallett, who joined Exscientia in January 2020, has an extensive background in medicinal chemistry and experience with companies such as Evotec and Merck & Co.

Elizabeth Crain has been appointed as the interim chair of the board. Crain is a co-founder of Moelis & Company and brings significant experience from her role on the board of Nokia Corporation.

Financial Impact

The leadership turmoil at Exscientia led to a sharp decline in the company’s stock, with shares dropping by 20% in early trading. Despite this, the company’s financial statements and internal controls remain unaffected by Hopkins’ conduct. It’s important to note that Hopkins’ termination is unrelated to Exscientia’s financial or operational performance.

Ongoing Commitments and Projects

Exscientia continues to focus on advancing its AI-driven drug discovery efforts. The company is committed to progressing its internal oncology pipeline and expanding its partnerships through innovative AI-based drug design and laboratory technologies. Despite the recent upheaval, Exscientia remains dedicated to its mission of discovering, designing, and developing effective drugs quickly and efficiently.

Key Collaborations

Exscientia has established several important collaborations with large biopharma companies. Notable partnerships include:

  • Sanofi: Up to $5.2 billion oncology and immunology partnership.
  • Bristol Myers Squibb (BMS): Over $1.3 billion partnership.
  • Merck KGaA: $20 million upfront with additional undisclosed milestone payments.

These collaborations underscore Exscientia’s strength in leveraging AI for drug discovery.

Recent Clinical Studies

One of the company’s latest developments is the launch of the EXCYTE-2 observational clinical study. This study aims to support the development of EXS74539, targeting acute myeloid leukemia (AML) and small-cell lung cancer (SCLC). The study will collect blood and bone marrow samples to explore the relationship between clinical response and drug response using deep learning and single cell precision medicine. Initial assessments will focus on newly diagnosed AML patients, with potential expansion to relapsing/refractory patients.

Drug Pipeline

Exscientia has streamlined its pipeline to focus on four key drug candidates:

  1. GTAEX617: A cyclin-dependent kinase 7 (CDK7) inhibitor for various cancer indications (partnered with GT Apeiron).
  2. EXS4318: A selective protein kinase C (PKC) theta inhibitor for immunology inflammation, partnered with BMS.
  3. EXS74539: A reversible lysine-specific demethylase 1 (LSD1) inhibitor for acute myeloid leukemia and small-cell lung cancer.
  4. EXS73565: A mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) inhibitor for hematological indications.

The decision to focus on these candidates reflects Exscientia’s goal of concentrating its R&D efforts on the most promising and differentiated oncology targets, ultimately aiming to bring new drug candidates to market.

Impactful Recognition

Despite the controversies, Exscientia and its former CEO were recently recognized for their contributions to AI in drug discovery. Andrew Hopkins was included in both Fortune magazine’s inaugural Fortune 50 AI Innovators list and Time magazine’s “The 100 Most Influential People in AI 2023.” This recognition highlights the significant impact Exscientia has made in the field.

Company Vision

Exscientia’s vision remains centered around using AI to revolutionize drug discovery. The company prides itself on its precision medicine approach, combining deep learning and laboratory technology to design effective drugs faster. This commitment was reinforced in the company’s statements following the leadership changes.

Organizational Structure

The company has restructured its board committees in light of the recent changes. Elizabeth Crain will serve on the Audit Committee, along with Robert Ghenchev and Franziska Michor. These committees will continue to oversee the company’s governance and strategic direction.

Financial Performance

Exscientia went public in September 2021, generating a significant $470.6 million in net proceeds. The stock performed well initially, peaking at $27.10 from an IPO price of $22. However, share prices have fluctuated, reflecting the dynamic nature of the market and recent events within the company.

Background of Andrew Hopkins

Before founding Exscientia, Hopkins had an impressive journey through academia and the pharmaceutical industry. He moved from South Wales to the University of Oxford, later working at Pfizer and the University of Dundee. At Dundee, he spun out a software company, laying the groundwork for what would become Exscientia.

Looking Ahead

Exscientia is in the process of looking for permanent successors to Hopkins and Nicholson. The company’s Nominating and Corporate Governance Committee has initiated the search for new leaders who can steer the company towards its future goals while maintaining its commitment to ethical standards and innovative AI-driven drug discovery.

Strategic Focus

Exscientia’s strategic pruning of its pipeline reflects a focus on the most promising drug candidates. By narrowing down to four key candidates, the company aims to enhance its R&D efficiency and deliver high-value oncology treatments.

Innovative Approaches

The company’s use of AI in drug discovery is a standout feature. By integrating deep learning and precision medicine, Exscientia aims to create highly differentiated molecules. This approach ensures that their drug candidates offer clear advantages over existing treatments, which is crucial for gaining regulatory approval and market success.


Despite a turbulent period marked by significant leadership changes, Exscientia remains focused on its core mission. The company’s commitment to leveraging AI in the drug discovery process positions it well for future success. By focusing on high-value oncology targets and forging strong industry partnerships, Exscientia aims to continue making substantial advancements in precision medicine. With a robust drug pipeline and ongoing clinical studies, the company is well-placed to meet its ambitious goals and deliver innovative treatments in the fast-evolving pharmaceutical landscape.
