This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20220817005681/en/

Recent developments in the Company’s pipeline, collaborations, and operations, as well as financial results for the second quarter and first half 2022, are summarised below. In addition, Exscientia will host a conference call Thursday, August 18 at 1:30 p.m. BST / 8:30 a.m. ET to provide an overview of the company’s pipeline and corporate strategy.

“In the first half of 2022, we delivered on major new and existing collaborations, advanced our pipeline programmes, and marked the 10-year anniversary of Exscientia’s founding. Over the past decade, we’ve pioneered an AI-driven approach to modernising drug discovery and development, and it was fitting that this quarter we also announced topline data from our EXS-21546 programme, one of the first AI-designed molecules to enter clinical trials,” said Andrew Hopkins, D.Phil., Exscientia’s founder and Chief Executive Officer. “With over $730 million in cash, we believe we are in a strong position to deliver across our portfolio of drug projects for the long-term. Our strategy creates an agile interplay between our internal pipeline and partnered programmes, enabling us to move candidates between the two depending on the best fit for Exscientia and our partners, as well as how we can best impact the probability of success for patients.”

Recent Highlights

Progress across internal and partnered pipeline, leveraging the Company’s precision medicine platform, as well as key components of Exscientia’s technology and operations.

Internal pipeline

Wholly, majority and co-owned programmes focused on areas in which Exscientia believes it can improve the probability of success, including precision oncology

• Following topline data in June, the Company remains on track to initiate a Phase 1b/2 study of EXS-21546 (majority owned with Evotec) in the second half of 2022
  • Phase 1b/2 study will be optimised with simulation-guided clinical trial design principles as well as leverage Exscientia’s precision medicine platform to maximise potential impact to the most relevant patients
• GTAEXS-617 (co-owned with GT Apeiron) CTA submission expected by year-end 2022
  • CTA and IND-enabling studies are ongoing, including translational work to support planned clinical trials expected to start in the first half of 2023

Partnered programmes

Utilising a scalable end-to-end platform to advance a broad pipeline, while also generating significant cash inflows to support advancements

• First two targets identified in new Sanofi collaboration for oncology and inflammation & immunity, respectively
• First precision medicine project initiated; focused on patient enrichment for a Sanofi biologic in oncology
• Advancing Bristol Myers Squibb (BMS) collaboration with continued progress across both BMS1 and BMS2 collaborations
• Following the achievement of recent successful drug discovery milestone, Exscientia and Bayer have mutually agreed to end collaboration; Exscientia will retain optionality to develop one of the two targets pursued under the collaboration
  • The Bayer agreement was the last Exscientia partnership based on AI-only design services, which included lower economics and reduced operational involvement in comparison with more recent partnerships
  • This update aligns with Company strategy to increasingly focus on programmes where Exscientia’s AI design, experimental biology and precision medicine platforms can be integrated

Recent clinical progress highlights ability of the Company’s advanced, AI-based platform to create novel molecules with high level of translatability to human biology

• Announced topline data from EXS-21546 Phase 1a healthy volunteer study in June 2022
  • The study demonstrated that observed human pharmacokinetics for EXS-21546 were in line with what had been designed for and predicted in preclinical modelling, supporting a twice-daily (BID) dose for continuous A_2A receptor inhibition over a dosing interval
  • EXS-21546 signalled inhibition of A_2A receptor was sustained over the BID dosing period, demonstrating a level of lasting target engagement
  • EXS-21546 was well-tolerated with no CNS adverse events reported in the SAD portion at all doses (30mg, 90mg, 250mg, 400mg) and in the MAD portion at 150mg BID

Exscientia’s approach allows for significant cash inflows to drive the business

• $111.0 million cash flow from collaborations in second quarter 2022, including $100.0 million from Sanofi, ending the first half 2022 with $732.0 million in cash, cash equivalents and short-term bank deposits
  • Includes constant currency mark-to-market foreign exchange impact of negative 8%
  • During the quarter, Exscientia recognised realised foreign exchange gains net of forward contract settlements of $14.0 million. The Company holds its deposits in both GBP and USD intended to match expected cash needs while limiting the impact of exchange rate fluctuations
• Second quarter 2022 net positive cash inflows from operations of $72.9 million

Expanded leadership team in critical growth areas

• Eileen Jennings-Brown joined as Exscientia’s Chief Information Officer, reporting to Garry Pairaudeau, Chief Technology Officer, and responsible for overseeing IT and DevOps. Ms. Jennings-Brown brings more than 25 years of experience across IT roles, including most recently heading technology for the Wellcome Trust.
• Charlotte Deane, Ph.D., Chief Scientist of Biologics AI, who joined Exscientia in January 2022, was awarded an appointment to the Most Excellent Order of the British Empire (MBE) for leading the UK Research and Innovation’s rapid response call for projects addressing issues arising from the pandemic.

Select peer-reviewed publications and scientific meeting presentations during the quarter

• “Coverage Score: A Model Agnostic Method to Efficiently Explore Chemical Space,” was published in the Journal of Chemical Information and Modeling in July 2022. This advancement in active learning allows more efficient exploration of chemical space, potentially leading to increased diversity of candidates, faster model improvement and shorter time to candidate identification
• “Surface Plasmon Resonance Screening to Identify Active and Selective Adenosine Receptor Binding Fragments,” a study which further validates Exscientia’s innovative biosensor approach to screening wildtype GPCR targets to advance drug discovery, was published in the ACS Medicinal Chemistry Letters in June 2022
• Three posters presented at the AACR Annual Meeting in April, highlighting Exscientia’s human tissue precision medicine platform, including potential benefits of Exscientia’s AI-driven design to overcome known issues such as potency, toxicity and selectivity and improve patient outcomes
