Knowledge gained about drug safety and effectiveness from controlled environments (e.g. clinical trials), although essential, does not provide a complete picture of the impact of drugs in the larger population. Post-market research can fill this gap by tracking unexpected adverse events associated with particular drugs and drug combinations, as well as measuring new biological sources that may better indicate drug toxicity. Such data sources are massive in size and pose significant analytical challenges. We illustrate integrative statistical methods applied on these types of massive data in post-market research to gain insight into drug toxicity and underlying biological mechanisms.

Learning Objectives:

  1. To demonstrate the application of association rules to mine adverse event reporting databases.
  2. To illustrate the use of novel sparse multivariate statistical methods to uncover cross-correlations in toxicogenomics data.
  3. To highlight challenges in high-dimensional drug safety data analysis.
