Organovo and Its Customers Present Data Supporting 3D Bioprinted Liver and Kidney Tissues for Drug Toxicity Testing

SAN DIEGO, March 13, 2017 (GLOBE NEWSWIRE) -- Organovo Holdings, Inc. (NASDAQ:ONVO) (“Organovo”), a three-dimensional biology company focused on delivering scientific and medical breakthroughs using its 3D bioprinting technology, today announced eight presentations at the Society of Toxicology’s (“SOT”) 56th Annual Meeting and ToxExpo, March 12–16, 2017, in Baltimore.  These presentations demonstrate the broad applicability of Organovo’s ExViveTM 3D Bioprinted Human Liver and Kidney Tissues for the assessment of drug safety and the detection of multiple clinically-relevant modes of liver injury and kidney toxicity.  In addition, Organovo has been invited to speak at a scientific symposium on next-generation models for toxicology.

“We’re pleased by the strong early feedback on our newest product, the ExVive Human Kidney Tissue, and the ongoing uptake and validation of ExVive Human Liver Tissue by our customers and partners,” said Dr. Sharon Presnell, chief scientific officer, Organovo.  “The commercial launch of our kidney proximal tubule model, in addition to our recent peer-reviewed publication highlighting its potential to become a key preclinical model for in vitro kidney toxicity testing, demonstrates our commitment to delivering novel tissue models using our platform technology.  We are expanding our portfolio by adding new tissues and by validating the use of our existing tissues across a broader set of applications.  The unique ability of our human liver model to reveal mechanisms of action for drug-induced livery injury (“DILI”) and model key aspects of chronic, progressive liver diseases such as fibrosis continues to put us at the forefront of in vitro human tissue modeling.”

"Our powerful and versatile technology platform delivers 3D bioprinted tissues that provide an accurate, predictive and reproducible model of human liver and kidney biology for preclinical toxicity testing,” said Paul Gallant, general manager, Organovo.  “Customer adoption of our NovoView Preclinical Safety Services for hepatoxicity testing continues to be strong, with a growing list of applications and use cases driving market adoption including investigative toxicology, evaluation of different compound modalities and fibrosis modeling for drug discovery.  The demand for our drug safety testing services has been growing since its introduction, and long-term market adoption is expected to be robust given the significant gap it closes against traditional preclinical models.  At this year’s SOT Annual Meeting, we will build on our sales momentum by continuing to show that our 3D bioprinted tissues effectively model in vivo composition and physiology.”

The presented data supports the use of the ExVive Human Liver and Kidney Tissue Models in:

  • Differentiating high-risk compounds from low-risk to evaluate the multiple pathways and mechanisms of DILI.
  • Identifying the metabolite-driven tox mechanisms of compounds such as acetaminophen in a concentration- and dose-dependent manner, thereby modeling tissue-level clinical outcomes in vitro.
  • Characterizing the role of Kupffer cells (KCs) in modulating the outcome of drug-induced liver fibrosis.
  • Demonstrating sustained metabolic capacity over time in terms of metabolic enzyme expression, metabolite formation, and gene expression levels to assess slow developing DILI toxicities.
  • Illustrating the multiple mechanisms of nephrotoxicity to evaluate the progression and subsequent recovery of tissue-level injury.
  • Assessing the expression, polarized localization and function of renal transporters involved in drug-induced renal toxicity.

In addition, the Colgate-Palmolive Award for Student Research Training in Alternative Methods, which is supported by Organovo, will be presented to a doctoral candidate to study the dose-dependent impact of an environmental toxin and the underlying mechanisms using ExVive Human Liver Tissue.
