Comparison of guidelines for biological ancillary materials used for the manufacture of gene and cellular therapy products in Asia

초록

Background aims: Although biologiocal ancillay materials (AMs) have specific risk associated with their deri-vations, it plays key role to manufature cell and gene therapy (CGT) products. It is important to understand the regulation relevant to AMs for developers.Methods: The authors investigated the guidelines and pharmacopeia (hereinafter referred to as "guidelines") for biological AMs used for the manufacture of CGT products in Asia (China, India, Japan, Korea and Taiwan). In addition, the authors benchmarked the relevant guidelines in the United States (US) and European Union (EU).Results and discussions: The guidelines could be classified into two types based on whether specific AMs are scoped: (i) general guidelines for risk assessment of AMs and (ii) guidelines for specific AMs. The authors com-pared the risk categories for each type of AM provided in the general guidelines between the US and China and the specific requirements for bovine serum and trypsin in the guidelines of China, Japan, Taiwan, US and EU. The authors further compiled in-depth descriptions of the respective regulations in China, India, Japan, Korea and Tai-wan. There is limited availability of some guidelines for specific AMs. Moreover, there are no common require-ments established across the surveyed countries and regions. Therefore, the authors suggest a risk assessment approach for AMs with consideration of their biological origin and traceability, production steps applied and abil-ity to control or remove AMs from the final medicinal product over the CGT manufacturing process.
