Office of Study Integrity and Surveillance
To ensure data supporting regulatory decisions are reliable by conducting and directing inspections of bioavailability/bioequivalence (BA/BE) and nonclinical (GLP) studies submitted to FDA.
OSIS staff support FDA's mission to protect the public health by:
- Conducting comprehensive study-directed and surveillance inspections of firms that conduct pharmacokinetic, bioavailability/bioequivalence (BA/BE), Good Laboratory Practice (GLP), and Animal Rule (AR) studies in support of human drug applications.
- Developing and refining strategies to improve inspection planning, execution, evaluation, and provide recommendations to CDER review divisions, while focusing on human subject safety and data integrity.
- Conducting outreach through participation in national and international conferences and workshops, and collaborating with international regulatory agencies by conducting joint inspections, observed inspections, and shared training.
