Patients frequently use more than one medication at a time. Unanticipated, unrecognized, or mismanaged drug interactions are an important cause of morbidity and mortality associated with prescription drug use and have occasionally caused the withdrawal of approved drugs from the market. Clinically relevant drug interactions between an investigational drug and other drugs should therefore be assessed during drug development using nonclinical and clinical assessment and are a regulatory requirement to obtain approval.

Course Objectives:

During drug development, the in vitro drug metabolism and drug transporter interaction studies should allow to understand the need for and the timing of clinical drug interaction studies. These in vitro studies should be completed before the product is administered to patients who are likely to take concomitant medications that could interact with the investigational drug. These studies should assess the effect of the investigational drug as a perpetrator on the marketed drugs that can be co-administered as victims. At the same time, these studies should assess the effect of the marketed drugs as perpetrators on the investigational drug as a victim. This information will also prevent patients from being unnecessarily excluded from any clinical study because of their concomitant medication use. Unnecessary restrictions on patient enrollment can result in clinical study populations that are not representative of the indicated patient population. Finally, an inadequate evaluation of the drug interaction potential will negatively affect the ability to determine the benefits and risks of an investigational drug. The objectives of the course are to cover and explain all these aspects.

Why Should You Attend:

Many drugs undergo metabolism to be eliminated from the body. Drugs can be metabolized in several organs; however, drug metabolism primarily occurs in the liver and intestine. These organs express a wide variety of drug metabolizing enzymes and are responsible for the biotransformation of many drugs. Hepatic metabolism occurs primarily through the CYP family of enzymes located in the hepatic endoplasmic reticulum. The potential for interactions between these metabolizing enzymes and investigational drugs, by initiating in vitro metabolic studies before first-in-human studies to inform the need for and design of clinical PK studies, are a regulatory requirement. In order to obtain a market authorization, drug makers need to assess the potential for a new drug to generate clinically relevant drug interactions. It is therefore important for all involved in this field to have a basic understanding of drug interactions and of how this is investigated during drug development.

Course Outline:

The topics that will be discussed during the webinar include the investigation of CYP enzyme- and transporter-mediated drug interactions to:
• Determine whether the investigational drug alters the pharmacokinetics of other drugs
• Determine whether other drugs alter the pharmacokinetics of the investigational drug
• Determine the magnitude of changes in pharmacokinetic parameters
• Determine the clinical significance of the observed or expected drug interactions
• Inform the appropriate management
