Consideration of antibody drug conjugates development and regulation / 药学学报

Antibody drug conjugates (ADCs), as they combine the targetability of monoclonal antibody and cytotoxicity of small molecules, are a growing class of therapeutics for cancer. The key factor of ADCs development is the accurate selection of parameters including tumor target, monoclonal antibody, cytotoxic payload, and linkage strategy of antibody to payload. Here, we summarize the main elements in the structural design and the development of ADCs, as well as the regulatory consideration of product manufacturing and control, which would be helpful for the research and development of ADCs.

Chemistry, manufacturing and controls regulatory considerations for marketing authorization application of therapeutic antibody in China / 药学学报

The marketing authorization application is a milestone of drug life cycle, which indicates a candidate has potential to become a commercial drug. As of now, there are only 12 domestic therapeutic antibodies approved in China. The chemistry, manufacturing and controls (CMC) development and evaluation of monoclonal antibody were more challenging for both industry and authority agency. As the result of domestic biopharmaceutical industry development and implement of priority review system, the marketing authorization application of domestic antibody biosimilar and imported antibodies had dramatic increased in recent years. Thus, the CMC evaluation of monoclonal antibody become the important task of biological product's marketing authorization registration management. In the article, the CMC regulatory considerations for marketing authorization application based on author's review experience was proposed, in order to accelerate development and registration of commercial antibody in China.
