As a living cell product, chimeric antigen receptor (CAR)-T cell therapy displays multiple characteristics including the diversity of raw materials, the complexity of manufacturing process and the complementarity of quality control set. Pharmaceutical research and evaluation of CAR-T cell therapy are fundamentally different from small molecule and macromolecular recombinant proteins. Chemistry manufacturing and controls (CMC) review of investigational new drug (IND) submission for CAR-T therapy should especially pay attention to above unique characteristics and focus on potential risks to ensure clinical safety. Based on questions and concerns from recent CMC review practice and workshop on CAR-T cell therapy IND application, the critical points to consider for CMC study is proposed, and questions related to supplementation are also discussed in this review to accelerate the clinic translation of CAR-T therapy.
