Visit CDER Small Business and Industry Assistance Page

THIS WEBINAR will discuss:

• The importance of assessing the drug interactions involving therapeutic protein products, interactions cause by change of gastric pH level, and interactions affecting combined oral contraceptives.
• How to evaluate those drug interaction potentials for investigational drugs
• General considerations for designing clinical drug interaction studies and how the results may inform drug labeling
• Utility of the lists of drugs available on the FDA drug interaction websites and the relevance to drug development and clinical practice

INTENDED AUDIENCE

• Scientists and consultants involved with drug interaction assessments conducted to support IND/NDA/BLA/ANDA applications
• Academic researchers in fields investigating drugs interactions
• Regulatory reviewers and policy makers
• Healthcare providers prescribing drugs to patients or consulted by patients

TOPICS COVERED

• Updates on the FDA drug interaction websites
• When and how to evaluate the impact of investigational drugs on combined oral contraceptives
• When and how to evaluate the effects of gastric pH elevation caused by acid reducing agents on investigational drugs
• When and how to evaluate the drug interactions involving therapeutic protein drugs.

LEARNING OBJECTIVES

• Describe the FDA drug interaction website, understand the clinical relevance of the tables, and how those tables can be used by drug developer and health care providers to assess drug interaction risks.
• Discuss the framework to determine the need to conduct clinical studies to evaluate the effects of investigational drugs on combined oral contraceptives, how such studies may be performed, and how to communicate recommendations for use in drug labeling to mitigate the risk of drug interactions.
• Address the circumstances when clinical studies are needed to evaluate the impact of acid-reducing agents on investigational drugs and alternative approaches, how such assessments can be conducted, and how the results may inform drug labeling.
• Review various mechanisms of drug interactions involving therapeutic protein drug products, a framework to determine the risk of such interactions, and how to communicate the drug interaction risks and mitigation strategy in drug labeling.
