You are warmly invited to our complimentary webinar, where industry experts and Key Opinion Leaders in Non-alcoholic Steatohepatitis (NASH) will share clinical data on the utility of stain-free AI digital pathology (AI-DP) and its potential impact in NASH drug development. The presentations are dedicated to all representatives involved in therapeutic discovery and drug development for NASH.

Known to many of us as the gold standard in the diagnosis and assessment of NASH, the liver biopsy is imperfect and has its limitations. Subjective inter- and intra-observer interpretations and staining variations are some of the issues that have been widely discussed in multiple presentations and publications. As biopsy-based endpoints are critical in determining key disease characteristics and therapeutic efficacy, more data is evolving from the evaluation of suitable and innovative approaches to overcome these limitations. We trust that the collective takeaways from these presentations will encourage attendees in harnessing the capabilities of stain-free AI-DP to enhance histopathological outcomes.

Find out how stain-free AI-DP – incorporating Second Harmonic Generation (SHG) technology – has aided current clinical studies in NASH by:

  • enabling augmented histological readouts and optimizing the assessment of treatment-induced responses on a granular level, and;
  • overcoming staining-related variations in a liver biopsy and providing consistent and reproducible AI readouts in a fully quantitative measurement.

Prof. Nikolai Naoumov MD, PhD, FRCP, FRCPath, FAASLD
Adviser for Digital Pathology and Drug Development in Liver Diseases 

Prof. Nikolai Naoumov is a physician-scientist with a professional career spanning academia, clinical care and drug development, all focused on liver diseases. He is Fellow of both the Royal College of Physicians (London) and the Royal College of Pathologists (UK). His research integrated immunology, molecular biology and translational medicine in elucidating virus-host interactions and mechanisms of liver injury. Prof. Naoumov led research teams at King’s College Institute of Liver Studies, London and subsequently as Professor of Hepatology at University College London. Between 2007 and 2021, Prof. Naoumov expanded his contributions to medical science and clinical hepatology as senior executive at Novartis Global Drug Development in Basel, Switzerland. As Global Head, Therapeutic area Hepatology and Transplantation he championed innovation, novel therapies and multiple industry-academia collaborations globally. In parallel, he continued contributing to liver research as Honorary Professor of Hepatology at UCL, trustee and adviser to the Liver Research Foundations in the UK and in Switzerland. Prof. Naoumov’s current work is focused on AI digital pathology, liver fibrosis, NASH and HBV cure.

Presentation Topic: Uncovering Novel Insights of Treatment-induced Fibrosis Regression in NASH with Stain-free AI Digital Pathology

Current scoring systems of NASH biopsies had been developed to assess fibrosis progression, and do not capture the full spectrum of treatment-induced changes. The second harmonic generation/two-photon excitation fluorescence (SHG/TPEF) microscopy provides a standardised and reproducible quantification of NASH fibrosis on a linear scale, as well as fine details of the collagen fibres.
At the EASL meeting in June 2021, we presented novel findings using SGH/TPEF microscopy with AI analyses in an exploratory investigation to gain in-depth understanding of the treatment response of tropifexor, a non-bile acid farnesoid X receptor (FXR) agonist, in patients with histologically proven NASH. The results, which will be presented and discussed during the webinar, demonstrate that SHG/TPEF assessment of unstained liver biopsies is a promising tool for quantitative evaluation of liver fibrosis with new parameters that cannot be detected by human eye. This approach provides new insights into the dynamics of fibrosis regression and treatment response, which are not captured by conventional staging systems.


Dr. Tim Kendall BM, PhD, FRCPath
Senior Clinical Fellow in Pathology and Honorary Consultant Pathologist, University of Edinburgh Centre for Inflammation Research; Edinburgh Pathology – The University of Edinburgh, UK

Dr. Kendall is a Senior Clinical Fellow in Pathology and Honorary Consultant Histopathologist. He obtained his Bachelor of Medicine and Ph.D. from the University of Southampton before undertaking post-graduate training in pathology in Southampton and then Edinburgh. He was appointed as an honorary consultant within NHS Lothian in 2011, specialising in liver pathology. Dr. Kendall is interested in hepatic myofibroblast biology, particular their role in liver scarring and primary and metastatic malignancy. He also undertakes histopathological review and scoring to facilitate translational and clinical research with local, national, and international collaborators. His particular interest is in quantitative and digital pathology in basic science and clinical research settings.

Presentation Topic: Overcoming Staining-related Variations in a Liver Biopsy with Stain-free AI Digital Pathology

Apart from gaining additional information from a liver biopsy that would prove valuable in determining treatment efficacy, AI-DP methods continue to show promise in potentially overcoming inherent inter-observer variation that occurs with manual scoring. A clinical study by the University of Edinburgh’s Centre for Inflammation Research and University of Nottingham’s Digestive Diseases Centre explored the pitfalls of staining and highlighted the following points on staining-related challenges:
– The study suggests that computational measures of liver scarring from stained sections are compromised by inter- and intra-laboratory staining.
– A stain-free quantitative SHG measurement avoids staining-related variations and shows potential in providing a more accurate and consistent detection of minute incremental changes in scarring that may arise in NASH clinical trials.
