Blood Cancer Research Releases Analysis Supporting Validation of AI-Based Precision Medicine Platform China Magazine

The results confirm that ex vivo deep learning screening of drugs from patient tissues is a promising tool for identifying effective individual treatments for advanced blood cancer compared to traditional methods.

Customized deep learning algorithms and single cell analysis of over 1 billion patient cells unlock additional potential to improve patient outcomes.

VIENNA AND OXFORD, England – (BUSINESS WIRE) – Exscientia (Nasdaq: EXAI), ETH Zurich, the Medical University of Vienna and the CeMM Molecular Medicine Research Center today announce a new publication in Blood Cancer Discovery, the journal of the American Association for Cancer Research, entitled “Deep Learning morphology enhances the accuracy of medicine with image-based ex vivo drug testing,” conducted by the laboratory of Professor Berend Snyder. This post hoc analysis is based on the pioneering work of the EXALT-1 study, published in the journal Cancer Discovery, using deep learning algorithms to classify complex cell morphologies into disease ‘morphotypes’ in patient cancer tissue samples.

EXALT-1 was the first prospective study to demonstrate significantly improved outcomes for patients with advanced hematologic cancer using an AI-based precision medicine platform to provide personalized treatment recommendations by comparing physician treatment choices. In the EXALT-1 study, 40% of patients experienced an exceptional response that lasted at least three times longer than expected for their respective disease. An a posteriori analysis published today in the journal Blood Cancer Discovery shows that the combination of the technology used in EXALT-1 with new advances in deep learning that take advantage of cell-specific characteristics in high-resolution image content has revealed potential for further improvement. these results for patients.

“Following the results of the EXALT-1 study, these observations continue to confirm that our AI-based precision medicine platform is able to identify actionable clinical recommendations for blood cancer treatment, our knowledge and improvement in the platform’s clinical predictive ability to help patients,” said Gregory Wladimir, MD. philosophy, vice president of translational research at Exscientia and co-investor in platform technology. “Cell morphology, or the evaluation of cell characteristics, is fundamental to the diagnosis of cancer. Through this study, we were able to use deep learning on the platform to improve our ability to identify personalized cancer treatments, leading to better clinical outcomes for patients. At Exscientia, we are excited to expand the platform’s applications to bring personalized medicine to a wider population. »

“We believe that performing drug screening directly in the tumor tissues of cancer patients is a big step forward in understanding the complexity of tumors compared to traditional cell model systems. The fact that we can now use the power of deep learning to turn these terabytes of images into useful information is really very encouraging,” added Prof. Berend Snyder, Principal Investigator at the Institute for Systems Molecular Biology at ETH Zurich.

The impact of deep learning on the clinical predictive power of ex vivo drug screening was assessed in a retrospective analysis of 66 patients over a three-year period in a combined dataset of 1.3 billion patient cells for 136 drugs tested ex vivo in hematology studies. diagnoses including acute myeloid leukemia, T-cell lymphomas, diffuse large B-cell lymphomas, chronic lymphocytic leukemia, and multiple myeloma. Patients treated with treatment recommended by platform immunofluorescence assay or deep cell morphology showed an increased rate of exceptional clinical response, defined as progression-free survival, that was three times longer than expected for each patient’s respective disease. Subsequent analyzes confirmed that clinical predictions became more accurate when the drug’s toxicity to healthy cells in the patient’s test sample was also taken into account.

Exscientia’s precision medicine platform uses special deep learning and computer vision techniques to extract meaningful single cell data from images rich in tissue samples from each patient. This analysis provides clinically relevant information about which treatment will be most beneficial for a particular patient. Further evaluating individual patient outcomes using Exscientia’s genomic and transcriptomic capabilities could help Exscientia better understand which other patients might benefit from a similar treatment. The underlying technology was developed by Dr. Gregory Vladimir and Prof. Berend Snyder while working in the laboratory of Giulio Superti-Furg at the CeMM Research Center for Molecular Medicine in Austria.
