An overview of cancer drugs approved through expedited approval programs and orphan medicine designation globally between 2011 and 2020.

The use of expedited approval pathways for anticancer drug development, which provide the advantages of high efficiency and cost-effectiveness, has expanded significantly in recent years. During the past decade, a total of 410 new molecular entities have been approved by the US Food and Drug Administration (FDA), with a steady growth of 6.5% in the US. In Europe, 9-75% of approved anticancer drugs were granted at least one expedited approval program. Various expedited pathways have also been implemented worldwide to address underrepresented medical needs rapidly. China has adapted several expedited approval programs, including breakthrough therapy designation, priority review, and conditional approval, to keep up with the growth in pharmaceutical development. It is expected that worldwide standards for drug approval will become more standardized in the next decade.
