In Vivo PK/ADME Studies — Positioning, Planning and Best Practices

In vivo studies, such as pharmacokinetics (PK) and absorption, distribution, metabolism and excretion (ADME), are critical to your compound’s vitality as you prepare for regulatory submission.

Knowing when these studies should be completed can often be a pressure point for drug developers. The design of your in vivo studies should be tailored specifically to your drug, but understanding the key requirements is essential in order to avoid under– or over–testing. Variations in analytical activities or deliverables can occur if a drug developer performs these studies earlier on, during the IND-enabling phase, compared to waiting until post-IND for a full, definitive package of studies.

Alfred Lordi, Director of Preclinical Services at WuXi AppTec Laboratory Testing Division, elaborates on this step in your compound’s program during his latest webinar titled, In Vivo PK/ADME Studies —Positioning, Planning and Best Practices.’

Lordi discusses some of the most pressing questions drug developers have, including:

  • Why are these studies needed?
  • What are the driving requirements?  
  • How are these studies designed and performed?
  • When should these studies be conducted?

In addition, Lordi shares insights into the key differences between governing agencies, and what each one expects in a drug developer’s PK and ADME studies.

This webinar will provide you with the background information you need to determine the right path for your compound and its in vivo PK and ADME studies.

DAR Research on ADCs Using LC-MS

Antibody drug conjugates (ADCs) refer to conjugated drugs formed by linking monoclonal antibodies with small molecule drugs that exhibit strong cytotoxicity through specific linkers. Depending on the structure of the linker, ADCs can be divided into two types: fractured and non-fractured. This composition means that ADCs possess the targeting ability of monoclonal antibodies and the characteristics of small molecule cytotoxic drugs, or as they are colloquially known, “precision-guided biological missiles.”  This also makes the structure of ADCs complex and diverse, making the pharmacokinetics of ADCs extremely challenging and uncertain. Therefore, ADCs have garnered considerable attention as a new and efficient antibody-based drug. In recent years, with the successful approval of multiple ADC drugs worldwide, particularly since 2019, when a total of 10 ADC drugs were approved, a new wave of ADC research has begun.

Transforming Drug Development: How Smart Compound Management Safeguards Integrity and Boosts Efficiency

In the current era of high-throughput screening and expansive compound libraries, traditional methods of compound management are becoming increasingly obsolete. Reliant on human handling and manual documentation, traditional systems often faltered under the pressure of scale, risking sample degradation, process inefficiencies, and delayed timelines. Early automation efforts helped address some of the procedural challenges by streamlining tasks such as weighing, plating, picking, and liquid handling, but bottlenecks remained. Persistent pressure points like sample integrity and process flexibility required more advanced intelligent solutions.
