A problem-oriented approach to safety issues in drug development and beyond.

Abstract

Human safety issues arise throughout the life cycle of pharmaceutical products and relevant information comes from a multitude of sources. Assessment and management of risks to humans requires a problem-based analysis to bring together relevant information regardless of source. The Safety Evaluation Plan (SEP) is a tool to support problem-oriented safety analysis. Safety issues are specified and the evaluation and management of each problem is based on a status summary that integrates the most current information from all relevant sources. The status summary is updated regularly during the course of clinical development to reflect the results of new studies and new clinical trials. In the postmarketing period, relevant postmarketing data is incorporated. Recent regulatory initiatives emphasise early identification of product safety risks so that appropriate risk-management measures can be instituted at the time of approval. A problem-oriented approach supports growing regulatory expectations regarding risk assessment and risk management. The problem-oriented approach facilitates early identification of safety issues and an evidence-based approach to their evaluation. Proactive management of safety problems leads to prompt assessment of risks and timely and appropriate steps aimed at risk reduction. The SEP provides a single global assessment for each safety issue. Regulatory submissions for pharmaceutical and biological products are organised by type of information. International Conference of Harmonisation documents covering clinical safety issues structure and analyse information separately by type, for example, adverse events, serious adverse events, laboratory data, vital signs, etc. A problem-oriented analysis would need to find a place in the regulatory process. A problem-oriented approach to safety cuts across typical structures in the pharmaceutical industry where different groups handle preclinical, clinical and postmarketing safety information. The SEP can improve communication within the company and externally. Nonetheless, supporting structures need to be adapted to support such an interdisciplinary process. Overall, the problem-oriented approach, supported by a SEP, contributes to realistic expectations and sustained credibility when dealing with safety issues.
