**"Evaluation of Adverse Drug Properties with Cryopreserved Human Enterocytes and Hepatocytes"**

Dr. Albert P. Li, CEO and President, IVAL

The liver and intestines are two major organs with extensive xenobiotic drug metabolism activities. The application of cryopreserved hepatocytes and enterocytes to evaluate drug metabolism, drug-drug and food-drug interactions, and drug toxicity will be described. A novel system, MetMax™ hepatocytes, as an exogenous metabolic activation system for proto-toxicants, will be introduced.

May  2016:

IVAL is named as a semi-finalist in the "Transform Tox Testing Challenge" created to improve chemical screening.

IVAL continues its series of innovative approaches to the comprehensive understanding of toxicity. The Transform Tox Testing Challenge was created by a coalition of Federal Agencies: the Environmental Protection Agency (EPA) and the National Institutes of Health (NIH) the National Center for Advancing Translational Sciences (NCTAS), National Institutes of Health NIH's Nation Toxicology Program (NPA) within the National Institute of Environmental Health Sciences (NIEHS). The purpose of the challenge is to more fully evaluate the potential harmful effects of chemicals found in the environment by using High Throughput Screening (HTS) approaches.

IVAL has developed a unique patent-pending approach using the Exogenous Metabolism System (EXM). The EXM consists of a transwell insert containing human or animal hepatocytes. The EXM insert is placed into a cell culture well containing the target cells used for toxicity evaluation, serving as an exogenous hepatic metabolic system.

IVAL Webinar: Hep-I-Spheres: 3D in vitro liver test systems for ADME-Tox research
February 24, 2016

Hep-I-Spheres, IVAL's newly-developed hepatocyte spheroids, are a useful tool for preclinical toxicity assessment of new compounds. These uniform and organized cell aggregates offer liver-like morphology and function in long-term cultures that can closely simulate in vivo drug exposure conditions.

This webinar will discuss our development of reproducible primary human hepatocyte spheroids, discuss data from both mono-culture and co-culture preparations, and help attendees better understand how studies performed using this test system bring additional value to their drug development program.

Webinar: "Enterocytes and their importance in preclinical pharmaceutical development efforts"
December 3rd, 2015
11:00 am Eastern / 8:00 am Pacific

Enterocytes are responsible for first-pass metabolism and are the key cell type for assessing oral bioavailability. With CYP3A4 activity comparable to that of human hepatocytes, enterocytes are a useful in vitro test system for the investigation of intestinal drug metabolism, drug-drug interactions, and toxicity assessments.

In this webinar, you will learn how IVAL's cryopreserved enterocytes maintain their enzyme activity after thawing and have been shown to produce clinically-observed phenomena, such as time-dependent inhibition of CYP3A4 by grapefruit juice.

The Novel IdMOC Experimental System for in Vitro Evaluation of Cell-Cell Interactions
Speaker: Albert P. Li, In Vitro ADMET Laboratories LLC, Columbia, MD

Date: Friday, March 6, 2015

Time: 1:00 – 3:00 PM

Room: Expo Hall, San Diego Convention Center

Poster Board Number: FRI-336

The novel integrated discrete multiple organ co-culture (IdMOC) experimental system allows the co-culturing of multiple cell types as physically separated entities but interconnected by a common overlying medium. The system employs a wells-in-a well concept, with multiple shallow wells inside a larger containing well. The formats include 6, 48, and 96 inner wells within each containing well. As the IdMOC plates have the same foot-print of regular 24- and 96-well plates, experiments can be performed with the plates without the need of special equipment as required for micro-fluidic co-culture systems. The IdMOC system can be used with adherent cells as well as non-adherent cells as matrigel entrapped cultures. Proof of concept experiments were performed demonstrating endocrinal cell-cell interactions, with soluble factors produced by one cell type interacting with a different cell type in the co-culture. Primary human hepatocytes and primary human splenocytes were plated in IdMOC-96 plates (96-well plate format, with 16 containing wells each with 6 inner wells). The co-cultures were treated with cyclophosphamide at 100, 200, 500, 1000 and 2000 uM. In vitro immunotoxicity was quantified via ATP contents in the presence and absence of phytoagglutinant A (PHA), with PHA-induced cell proliferation as a measurement of immune function. Cyclophosphamide induction of immunotoxicity was observed in splenocytes co-cultured with hepatocytes, but not in the absence of hepatocyte co-culture. The results suggest that IdMOC system can be used for in vitro evaluation of cell-cell interactions via secreted soluble factors. Examples of applications include the evaluation of endocrinal interactions among cells of different organs, and paracrinal interactions among cells from the same organ.
