WHO/KFDA joint workshop on implementing WHO guidelines on evaluating similar biotherapeutic products, Seoul, Republic of Korea 24–26 August, 2010

AbstractIn August 2010, the World Health Organization and the Korea Food & Drug Administration jointly organized the first implementation workshop of WHO guidelines on evaluating similar biotherapeutic products (SBPs) at the global level. The objective of the Workshop was to facilitate implementation of the newly adopted WHO Guidelines into the practice of national regulatory authorities (NRAs). WHO Guidelines were recognized by the workshop participants as a tool for harmonizing regulatory requirements worldwide. By reviewing and practicing several case studies, better understanding and consensus on the principles of clinical trial designs were reached. However, variations in terms of the national requirements for quality, safety and efficacy of these products revealed diversity in the regulatory expectations in different countries and regions. In addition, lack of terminology for the products developed as copy products (so called "me too" products) with a partial comparability to an RBP, led to a great diversity in evaluating as well as naming these products. The workshop participants proposed the following actions: a) NRAs should make efforts to build their capacities for regulation of SBPs; b) WHO should revise WHO Guidelines for assuring the quality of products prepared by recombinant DNA technology (WHO TRS 814) and continue monitoring progress with the implementation of the Guidelines on evaluating SBPs. Publication of the outcome of the Workshop was recognized as another action that WHO should coordinate
