Drug-induced liver injury (DILI) is the leading cause of acute liver failure and a major reason for liver transplantation. One of the most prominent forms of clinically observed DILI is cholestatic DILI. Cholestasis is characterized by impaired hepatic bile flow and may be induced by several different mechanisms. Cholestatic DILI can occur as the sole DILI phenotype or as a comorbidity with other DILI phenotypes. This from BioIVT looks at the effect of drugs that cause cholestatic DILI on bile acid transport and metabolism:https://assets.ctfassets.net/wirgejq7s9c7/41QTGN69yiDpteKZIzzvFV/a8e6cb6792c61eed25b324734ad27f84/ISSX_2022_Poster_Kralj_final.pdf

The unbound intracellular concentration (ICC) is the driving force for processes that occur inside , including , induction and inhibition (metabolic and ), efflux-based , and . The absence (or reduction) of any of these processes can result in sub-optimal predictions of effects. Model selection is critical for accurate prediction of in vivo effects.

We’re looking forward to presenting a on “Antibody drug conjugates (ADCs): In Vitro Evaluation of Potential” at next week’s Gordon Research Conference on progressing (https://www.grc.org/drug-metabolism-conference/2023/). Request a meeting with Dr. Limaye if you’ll be attending or would like to discuss: https://hubs.ly/Q01WwM5R0 and make sure to follow BioIVT to access the poster once it’s available: https://www.linkedin.com/company/bioivt/

Abstract: Antibody drug conjugates (ADCs) are a novel modality leveraging monoclonal antibody (mAb)-mediated delivery of a cytotoxic payload molecule to its target. The small molecule conjugated to mAb can be released in unconjugated form and contribute to the drug-drug interaction (DDI) potential, therefore, both the antibody and the small molecule drug component should be considered. Here we present the summary and outcome of in vitro DDI studies conducted for several ADC programs at our facility. These studies included metabolic stability, metabolite identification, reaction phenotyping of CYPs and UGTs, CYP inhibition and induction potential, UGT inhibition potential, and potential as a substrate or inhibitor of transporters…

With over 3500 respondents to our industry survey on when and why researchers are running various studies, including , and , 96% of respondents said they had experienced negative repercussions from postponing these studies.

Take a look at the survey results infographic to read about when most researchers are performing ADME/ & testing, see what the top 4 repercussions and risks are from postponing, and the top 3 benefits to running more testing during preclinical research: https://bioivt.com/resources/articles-publications?entry=vSvbCm8TSoCORIsRweJjT&utm_source=XTsocial&utm_medium=XTsocial&utm_campaign=XTFacebook&utm_id=XTFacebook&utm_term=IndustrySurvey

Since many compounds bind to red blood cells, which are 99% of cellular space in blood, determining parameters by only measuring drug concentration in plasma can significantly impact clearance and cause inaccuracies in calculations. That’s why the majority of polled researchers said they regularly conduct red blood cell partitioning with plasma protein binding studies.
