In Vivo ADME Testing in Drug Development: A Short Guide
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...
How to Improve PROTACs’ Oral Bioavailability
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...
How to Tackle the Developmental Challenges of PROTAC Drugs
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...
A Guide to In Vitro ADME Testing in Drug Development
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...
Maximizing the Efficiency of Ocular Gene Therapies
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...
Preparing Drug Developers for Developmental and Reproductive (DART) Studies
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...

Q&A: How Preclinical Toxicology Contributes to Successful IND Applications
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...
The Vital Role Of Toxicity Studies In Evaluating New Drugs
The evaluation of toxicity in a new drug is a very thorough process, so that by the end of the testing, scientists will have compiled all the necessary data to understand the full safety profile of the potential new drug. During that nonclinical evaluation, there are...
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...
