New digital pathology, quantitative image analysis and quantitative AI method for liver tissues is presented for the continuous assessment of the histological phenotype(s) of fibrosis, including severity and regression of fibrosis in Human in-vitro 3D NASH Spheroid models, NASH rodent models, Clinical Phase2b NASH Studies at the Liver Meeting Digital Experience™ 2021

PRINCETON, N.J. - November 12, 2021 - (Newswire.com)

PharmaNest is a digital pathology and artificial intelligence company that is focused on the development and validation of novel standards for quantification of the histological phenotype(s) of fibrosis and associated histological features for drug discovery and development. Launched in 2019, PharmaNest's FibroNest™ multi-vendor Quantitative Image Analysis and Quantitative AI platform automates the quantification of fibrosis and disease activity (Steatosis, Ballooning and Inflammation) for both non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH), using digital images of stained tissues. It is a for-research-only-use project at this time.

As a multi-vendor platform, FibroNest is compatible with all kinds of digital image formats, including conventional digital pathology-stained slides (Picro Sirius Red, Trichrome or Antibody stains for fibrosis) acquired by both FDA-approved, digital pathology scanners and other digital microscopes.

At the 2021 AASLD | The Liver Meeting Digital Experience™ (TLMdX), PharmaNest and its world-class academic and industry collaborators present results that demonstrate the translational capabilities of FibroNest across the drug discovery and development continuum including:

• The quantification of the progression of fibrosis in Human in-vitro 3D NASH tissue models and their response to Alk5 inhibitors and anti-TGB beta treatments - showing the utility of the combined technologies to accelerate the discovery of novel anti-fibrotic compounds, in a collaboration with InSphero (Schlieren, Switzerland).
• The comparison of Whole Slide Digital Imaging and Two Photon (Second Harmonic Generation) digital imaging using FibroNest™ to evaluate the anti-fibrotic and anti-steatotic effects of FXR agonists in Leptin-deficient mice food with high-fat diets (NASH model), in a collaboration with Intercept, Inc. (New York, USA).
• The development and validation of a highly sensitive, continuous digital pathology score, used to classify patients between NASH Fibrosis stages of F2 and F3, with a sensitivity and specificity performance of more than 90%, in a collaboration with Virginia Commonwealth University (Richmond, USA), Bristol Myers Squibb (Princeton, USA) and University of California (San Diego, USA).
• The quantification of the histological phenotypes of fibrosis in LEAN and OBESE patients with NAFLD and F2 / F3 fibrosis, and the comparison of these phenotypes, in a collaboration with the Yokohama City University School of Medicine (Yokohama, Japan) and The Chinese University of Hong Kong (Hong Kong).
• The development of a digital pathology score to automatically classify F1 NASH patients into sub-stages, such as F1a, F1b and F1c, in a collaboration with Lipocine, Inc (Salt Lake City, USA) and University of California (San Diego, USA).

In addition, several other communications at AASLD | TLMdX, 2021 will present the contribution of FibroNest's Digital Pathology and Quantitative AI platform in the quantification of novel drugs investigated in Phase2b studies, such as the LPCA 1144 Therapy (a collaboration with Lipocine, Inc., Salt Lake City, USA).

These results will be presented at The Liver Meeting Digital Experience™ (TLMdX) 2021 at the following poster presentations.
