"Risk Assessment and Mitigation Strategies" (REMS) are procedures used by the U.S. Food and Drug Administration (FDA) to manage known or potentially serious risks associated with a drug to ensure that the benefits of the drug outweigh its risks. CAR-T cell therapy has brought new hope and new options for cancer patients due to its excellent efficacy. However, due to the characteristics of its treatment principle, almost all CAR-T cell therapy may lead to some adverse reactions. Cytokine release syndrome (CRS) and neurologic toxicities (NT) are the most common. This paper intends to analyze the post-marketing risk management strategies of CAR-T drugs in the United States by exploring the content of REMS in the risk management strategies of CAR-T drugs, and takes Kymriah, a CAR-T product currently on the market in the United States, as an example to analyze the specific implementation of the strategies. The purpose of this paper is to provide reference for the authorities to develop related policies of CAR-T drug listing risk management in China.
