Drug discovery and development is difficult and requires knowledge, commitment, insight and perhaps an attitude best described by Winston Churchill (1874-1965)....
“Success is the ability to go from one failure to another with no loss of enthusiasm....”
A major reason for new drug candidate failure 24 years ago was lack of adequate pharmacokinetics (PK) in humans (the ability of the drug to be absorbed into the body, reach the target organ and remain there long enough to yield therapeutic effect)- 48% of new candidates failed in 1991 because of inadequate PK. Seventeen years later in 2008 this rate of attrition was reduced <1% until at present drug failure due to inadequate PK is nearly nonexistent.
This is because of the tremendous increase in the number of inexpensive and predictive in vitro PK assays now available to discovery teams in the development process. My course,Application of Pharmacokinetics and Safety Pharmacology for Chemists in Drug Development, guides students in the optimal use of these new assays to achieve acceptable PK for new drug candidates. After attending this course students will be able to define PK/PD principles and terminology, review developments in drug discover, investigate the application of drug development principles, and much more.
