Quantitative whole-body autoradiography (QWBA) and mass balance testing are equally important processes to gather data on a drug candidate’s absorption, distribution, metabolism, and excretion (ADME) properties. While both QWBA and mass balance can give details...
IND-enabling testing is a cornerstone of the drug development process, helping researchers predict safety concerns and estimate safe and efficacious starting doses for clinical trials. Planning ahead, understanding the tests you need to conduct, and diligent tracking...
In vitro and in vivo ADME studies provide valuable data about a test article as it moves through preclinical development. In this short guide, we provide an overview of in vivo ADME testing, including why it’s important and how it works. For a successful...
PROteolysis TArgeting Chimera (PROTAC)* drugs hold enormous potential. No PROTAC drugs have earned FDA approval yet, but they are being widely explored across industry and academia for an ever-expanding range of treatments. Part of PROTACs’ appeal is in their...
PROteolysis TArgeting Chimera, the novel therapeutic modalities better known as PROTACs*, first emerged in 2001 but are just starting to emerge from clinical trials. Their unique structure and capabilities have excited drug developers; however, there are still...
Understanding the Absorption, Distribution, Metabolism and Excretion (ADME) properties of a compound is critical to drug discovery and development. In this short guide, we look at how in vitro ADME testing works and why it is important. To understand in vitro ADME...
Gene therapy is an exciting—and relatively new—area of medicine. Treatments were first introduced in the 1970s, but after decades of methodology challenges and scientific frustration, the concept of altering genes to address “untreatable” viruses and diseases gained...
In 1993, the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) published guidance entitled “S5 Detection of Toxicity to Reproduction for Medicinal Products.” The U.S. FDA interpreted the ICH guidance and...
A new 108,000-square-foot testing facility in Chengdu, China, will allow WuXi AppTec to help meet high global demand for toxicology testing in preclinical studies. The facility significantly expands WuXi AppTec’s testing capacity at a time when many customers’...
For more than 20 years, WuXi AppTec has been a leader in developing and validating biomarker methods to support drug development and clinical research. It has used cutting-edge technology to validate hundreds of biomarkers on most major platforms with the aim of...
WuXi AppTec Laboratory Testing Division experts continually weigh in on emerging trends and stay updated on salient drug development topics. Here is a rundown of the industry publications featuring WuXi AppTec experts in the second half of 2021. 1. Genetic Engineering...
Preclinical toxicology testing on new molecules is essential. Researchers use toxicity tests to identify specific adverse effects related to cancer, cardiotoxicity and skin/eye irritation and sensitization. These in vitro and in vivo studies combine with accidental...
