IngentaConnect CIOMS and ICH Initiatives in Pharmacovigilance and Risk Managemen...

Abstract:

In this article we review the current initiatives by the Council for International Organizations of Medical Sciences (CIOMS) and the International Conference on Harmonisation (ICH) on pharmacovigilance planning that are due for general release during 2004. These initiatives could form the basis for applying concepts of risk management to medicines throughout their life cycle, from preclinical and clinical development to marketed use.

The CIOMS VI Working Group (with 28 senior scientists worldwide from drug regulatory authorities and pharmaceutical companies) is currently developing scientific guidance that relates to clinical trials for medicines during development. It recommends a developmental pharmacovigilance concept – a ‘living’ concept that would start early in drug development supporting the science and ethics of research leading up to licensing (marketing authorisation) and continuing to post-authorisation (postmarketing) pharmacovigilance.

This approach is seen as complementary to current ICH initiatives called ‘Pharmacovigilance Planning’. ICH will introduce two concepts in pharmacovigilance management of medicinal products: the ‘Pharmacovigilance Specification’ and the ‘Pharmacovigilance Plan’. The ‘Pharmacovigilance Specification’ will summarise important knowns and unknowns about the medicine. It will include safety risks identified at the licensing stage, potential risks and any key missing information. These elements will be essential to the formulation of pharmacovigilance plans.

Dialogue and common understanding between regulators and the pharmaceutical industry will be a key factor for developing pharmacovigilance plans during the life cycle of medicines. Appropriate interaction with health professionals and patients should also be planned for the future as regulatory systems become more transparent.

Where no significant issues are apparent at the licensing (marketing authorisation) stage, routine pharmacovigilance practices will be followed during the marketing phase. Where issues do exist or the data are limited, further study, including epidemiological approaches can be planned. All types of medicines (new drugs, biological agents, orphan drugs) may be involved in these concepts, as would major extensions to existing medicines.

Currently ongoing CIOMS and ICH initiatives are in line with emerging risk-management strategies in the US, the European Union and Japan aimed at early and proactive pharmacovigilance.
