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...
Regulatory Expertise
Navigating 505(b)(1), 505(b)(2) and 505(j) Drug Approval Pathways
Introducing new drug candidates to preclinical testing is a complex and time-consuming endeavor. It can cost developers more than $1 billion and take a decade to bring a new drug to market. Success rates vary depending on therapeutic area, but a recent study from MIT...
The Complex Process of Developing a Living Protocol
There are times in the laboratory when experienced scientists may question the direction in a protocol. Their experience, having worked on so many studies, may tempt them to consider conducting the testing a little differently than the directions provided to them. If...
Understanding Oligonucleotides and Their Bioanalytical Considerations
As new modalities in drug development gain popularity, we are in an exciting place to treat and prevent complex disease states. Researchers have been making great strides in the development of oligonucleotides, otherwise known as “oligos.” Though these therapies...
Basic Questions Developers Are Asking About In Vitro-In Vivo Extrapolation
In Vitro-In Vivo Extrapolation (IVIVE) is an emerging discipline that helps researchers predict the rate at which compounds metabolize within the human liver and are eliminated from the body (i.e., human clearance rate). Put simply, IVIVE uses in vitro methods to...
In The News: WuXi AppTec Experts In The Drug Development Community (Jan-July 2021)
WuXi AppTec Laboratory Testing Division experts continually weigh in on emerging trends and stay updated on salient drug development topics. These experts routinely contribute to industry publications. Here’s where they’ve been featured in the first half of 2021....
Testing Toxicity to Advance to Phase I Clinical Trials
Preclinical research teams enter each drug testing project with the same hope – that the drug will meet all the safety requirements in order to advance to phase I clinical trials in humans. In laboratory experiments, scientists will test their ideas for new...
Managing Critical Reagents: An Essential Part of Your Bioanalytical Strategy
Critical reagents are an essential part of bioanalytical testing for large molecule preclinical and clinical studies. These essential components help determine the accuracy of the analyte, precision and performance of ligand binding assays (LBAs), which are key to...
PROTACs and Their Role in Catalyzing Health Solutions
PROTACs, otherwise known as PROteolysis TArgeting Chimera, emerged as a novel therapeutic modality in drug development and currently show promising clinical results for tackling some of the most complex diseases. PROTACs are designed to leverage the body’s internal...
PART 1 – Understanding New Modalities: Oligonucleotides and Bispecific Antibodies
As our understanding of genomics and biological pathways expands, human diseases, once thought untreatable through conventional therapies, are well within our realm of intervention. Oligonucleotides ("oligos") and bispecific antibodies (BsAbs) are two new modalities...
PART 2 – Understanding New Modalities: Prodrugs, Cell/Gene Therapy and Fusion Proteins
New drug modalities, including oligonucleotides, bispecific antibodies, prodrugs, cell and gene therapies, and fusion proteins, offer new ways to treat human diseases once considered "untreatable." Cell and gene therapies have been around for years, but advancing...
ICH M10: Preview New Bioanalytical Method Validation Guidance
The International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) is in the process of revising M10, a multidisciplinary guideline that governs bioanalytical method validation. Drugs need to contain the correct...
