Pharmacokinetics (PK) and pharmacodynamics (PD) play a key role in drug development, and a good understanding of the implications of PK/PD data is crucial when designing clinical trials or preparing a drug submission dossier. As a professional working with PK/PD data on a regular basis, you must have a solid understanding of the topic to communicate effectively with the development teams – a daunting and challenging task, due to the breadth and complexity of the topic area.
This course assumes no prior PK knowledge and aims to give you a broad understanding of this fascinating subject, using multiple case studies and relevant examples. You will learn what pharmacokinetics involves, what data is collected, and its impact on the drug development process. By learning these skills, you will be able to understand, communicate, and challenge the data presented to you.
Why Should You Attend
To get a better understanding of the different aspects that contribute to the pharmacokinetic profile of a new chemical entity. PK studies asses drug exposure to facilitate drug development. PK studies offer great support to learn and confirm the key characteristics of new molecular entities in a quantitative manner. This provides evidences for optimizing drug development plans and enabling critical decision-making. Drug development without PK is considered at a higher risk of failure.
Key Learning Objectives
The course reviews the general concepts and basic elements of pharmacokinetics. The course will describe the processes that a drug undergoes after administration such as the absorption (when not administered intravenously), the distribution, including plasma protein binding, the metabolism (the biotransformation of the drug into its metabolites) and the excretion (via the bile in faces and via the kidney in urine). The use of PK during drug development will also be described. PK studies can facilitate knowledge management and decision making to streamline drug discovery and development and to reduce the attrition rate. The following topics will be discussed in details:
- Volume of distribution
- Plasma protein binding
- Elimination half-life
THE ROLE OF PK IN DRUG DEVELOPMENT
- What is PK?
- Pharmacology, pharmacodynamics, and pharmacokinetics
UNDERSTAND THE PK/PD MODEL OF THERAPEUTICS
- Dose, concentration, biophase, effect, clinical endpoints
THE IMPORTANCE OF PK THROUGHOUT DRUG R&D
- The Increasing Importance of PK In the Go/No Go Decision
- Inter disciplinary Interaction in The Pharmaceutical Industry – Let’s all Speak the Same Language
