14 Guidelines This presentation will focus on guidelines for CROs, then GCP and GLP What is a CRO: WHO: "any organization involved in the conduct or analysis of in vivo bioequivalence studies". Per ICH Tripartite Harmonized Guidelines: "a person or an organization (commercial, academic or other) contracted by the sponsor to perform one or more of a sponsor's trial-related duties and functions"

15 Research Organizations
Scope: Guidance to organizations involved in the conduct and analysis of in vivo bioequivalence (BE) studies Note: BE studies should be performed in compliance with: General regulatory requirements Good practices in the WHO bio- equivalence guideline, Good clinical practice (GCP) Good laboratory practices (GLP)

16 Research Organizations
Guideline provides information on: - organization and management; - study protocols; - clinical phase of a study; - bio-analytical phase of a study; - pharmacokinetic and statistical analysis; - study report.
