InSphero and Pharmaceutical Companies Form Pre-Competitive Consortium to Advance Development of In Vitro Tools to Screen and Predict Drug-Induced Liver Injury (DILI)

DILI is of significant concern to the pharmaceutical industry and regulatory authorities due to limitations of existing preclinical animal models. Founding members include Pfizer, Sanofi, Merck, and Genentech

Schlieren, Switzerland – June 16, 2021  InSphero AG, the pioneer of 3D cell-based assay technology today officially launched a pre-competitive consortium that brings together representatives from pharmaceutical companies engaged and invested in the development of cross-species drug testing and validation strategies for rapid, reliable drug-testing of drug-induced liver injury (DILI) and translation to humans.

The consortium will evaluate methods for recapitulating DILI-specific effects observed in animal models and patients using in vitro human and animal liver spheroid models and a DILI compound library.

“DILI is recognized as a significant cause of drug candidates being terminated during development or drugs being withdrawn from the market,” said Armin Wolf, Ph.D., Professor of Toxicology and Chief Scientific Officer at InSphero and former pharmaceutical industry executive.   “Preclinical safety assessment of drug candidates typically relies on animal testing. Unfortunately, this does not always reliably translate to humans. This shortcoming likely contributes to the prevalence of DILI reported in late-stage drug development. We intend to use 3D liver microtissues from animals and humans to evaluate DILI mechanisms leading to observed in vivo effects. Our goal is to help bridge the gap between human and animal in vivo and in vitro responses for a wide range of compounds and therapeutics.”

Each participating pharma member will provide a set of DILI compounds for 3D in vitro mechanistic investigations conducted by InSphero. These compounds may have failed or are from halted drug programs having a well-documented preclinical DILI-specific in vivo profiles and history in the most common regulatory animal models. For confidentiality reasons, the chemical structure and therapeutic target of test compounds will be blinded and not revealed in any consortium publications.

“The ability to accurately evaluate DILI potential in vitro across multiple species can be very useful to understand the human relevance of liver signals from in vivo preclinical studies” said Piyush Bajaj, Ph.D. senior principal scientist at Sanofi.

InSphero will employ a cross species DILI validation strategy to compare the documented in vivo response to the in vitro response in 3D liver microtissues derived from the corresponding preclinical animal models. Each type of drug-induced liver pathology will be investigated in vitro by the specific underlying DILI mechanism or biomarker. The validation criterion will be recapitulation of the documented in vivo DILI effect by mechanism in the relevant in vitro liver microtissue.

“Development of a reliable, in vitro hepatic platform capable of accurately translating the DILI risk of drug candidates across preclinical species and humans would help improve our ability to predict hepatic safety,” said Jonathan P. Jackson, Ph.D., senior principal scientist, Pfizer. This sentiment was emphasized by fellow consortium member Phil Hewitt, Ph.D. global head of early investigative toxicology at Merck Healthcare KGaA who noted “Having a validated liver model for all relevant preclinical test species would greatly improve our ability to both predict DILI and retrospectively assess potential clinical mechanisms.”

Another important aspect of developing robust and predictable in vitro models for safety assessment is the potential to reduce the use of animals for this purpose. “From a practical standpoint, the most important factor to enable utilization of these new models effectively is having enough foundational high-quality data available to understand the appropriate context of use,” said Leah Norona, Ph.D., scientist at Genentech, Inc. “This consortium will take the critical first steps towards that goal.”
