Analysis of post-marketing requirements for oncology drug conditional approvals in the United States and China

Conditional approvals, also known as accelerated approvals, have been introduced by many pharmaceutical regulators around the world, allowing innovative drugs to enter the market earlier on the basis of limited evidence. This research aims to systematically analyze and compare the post-marketing requirements for conditional approvals of oncology drugs in China and the United States. By collecting and categorizing different types of post-marketing requirements, this study seeks to elucidate how these requirements are proposed and discern the underlying logic and patterns.
