A New Method to Improve Identification of the Payload-Containing Catabolites of ADCs
Antibody-drug conjugates (ADCs) are a relatively new medicine with the potential to target cancer cells and deliver a toxic payload, all while minimizing any damage to otherwise healthy body parts. ADCs have a number of strengths, but perhaps chief among them is...
Improving PROTAC Drugs with MetID Studies
Most drugs undergo some level of transformation once they enter the body. This metabolism process allows a drug's active pharmaceutical ingredient (API) to achieve its desired effect and eliminate it from the body. But metabolism can also be tricky. Metabolizing a...
Using High Resolution Gas Chromatography to Keep Costs in Control While also Protecting Patients
High-resolution quadrupole time-of-flight (QTOF) gas chromatography–mass spectrometry (GC-QTOF-MS) provides a powerful combination of high mass accuracy with trace level detection capabilities. Applying the technique to extractables and leachables testing (E&L)...
What Are Metabolite Profiling & Identification Studies?
Drug metabolism studies (the “DM” of DMPK) are a critical part of understanding drug efficacy and safety across the entire drug development continuum. In this blog, we provide an overview of metabolite profiling and identification studies, including: four types of...
GLP vs. Non-GLP toxicology studies: When to use which guidelines?
Since 1978, when the U.S. FDA issued the Guidance for Industry Good Laboratory Practices Regulations, Good Laboratory Practices (GLP) have been an essential part of the quest to ensure the highest standards in drug development. GLP regulations have ensured that...
Drug-Drug Interaction: An Overview of Substrates and Metabolizing Enzymes
Drug-Drug Interactions (DDIs) occur when a drug affects the efficacy of another drug that is being co-administered, which can result in unexpected side effects. Most drugs are metabolized in the body by enzymes, and changes to these enzymes can alter the effects of...
The Inherent Challenges of Antibody-Drug Conjugate (ADC) Bioanalysis
Antibody-drug conjugates (ADCs) target and destroy cancer cells like few available therapies. Highly potent and laser-focused, these tools have been around since 2000; currently, just 14 of them have been approved for use. ADCs are made up of a monoclonal antibody, a...
4 Critical In Vitro Genotoxicity Assays for Preclinical Drug Development
Genetic toxicology studies are an integral part of the basic toxicological information package used in the risk assessment and decision-making process for a new drug. In this short guide, we walk through four critical in vitro genotoxicity assays drug developers need...
Reproductive Toxicology & the EPA’s Tiered Testing System
The endocrine system comprises myriad glands, hormones and receptors throughout the body that regulate biological processes from birth to death. Chief among those processes is the differentiation, growth and function of the human reproductive system. Human...
As Requirements for E/L Testing Continue to Increase—Here Is What You Need to Ask When Selecting A Testing Partner
U.S. Pharmacopeia (USP) recently issued two new chapters (665/1665) on production equipment and patient safety for polymeric components and systems used in biomanufacturing. These new requirements demonstrate a heightened focus on the extractables and leachables in...
5 Critical Nonclinical Toxicology Studies Required for IND Submission
Toxicology studies are required for Investigational New Drug (IND) and New Drug Application (NDA) submissions in order to fully define the safety profile of a drug – and maintain the highest level of patient safety. In this short guide, we cover the core battery of...
The Secret Recipe for Extractable/Leachable Testing Success
Every great chef has a secret "something" to their name—a recipe, a technique, an ingredient. It stands to reason that a lab essentially concerned with chemistry would also have its own special something. After all, cooking is a form of chemistry, isn't it? While some...
