The RACE Act and Pediatric Trials of Adult Cancer Drugs.

BACKGROUND AND OBJECTIVES: Adult cancer drugs have historically been exempted from pediatric testing requirements. In 2017, Congress passed the Research to Accelerate Cures and Equity (RACE) for Children Act to expand mandatory pediatric testing to cancer drugs; the law took effect in 2020. With this study, we sought to evaluate how the pediatric testing of molecularly targeted adult cancer drugs changed after the RACE Act. METHODS: In this retrospective cohort study, we used publicly available Food and Drug Administration data to compare pediatric post-approval requirements, trials, and trial characteristics, including timing, in adult cancer drugs before and after the RACE Act. RESULTS: Between 2017 and 2024, the Food and Drug Administration approved 61 adult cancer drugs with molecular targets relevant to pediatric cancer; 40 were submitted before 2020, and 21 were submitted after 2020. The 40 pre-RACE Act drugs were associated with no pediatric post-approval requirements, whereas the 21 post-RACE Act drugs were associated with 15 pediatric post-approval testing requirements. Approximately two-thirds (26/40, 65%) of pre-RACE Act drugs and 57% (12/21) of post-RACE Act drugs were evaluated in pediatric trials. Among pre-RACE Act cancer drugs, pediatric trials were initiated a median of 0.04 years after approval (interquartile range: -3.3 to 1.9 years), whereas post-RACE Act trials were initiated a median of 2.8 years before approval (interquartile range: -4.3 to 0.3 years). CONCLUSIONS: The RACE Act has been associated with greater numbers of pediatric postapproval testing requirements and the earlier initiation of pediatric trials, although early pediatric trial rates appear unchanged. Formalizing pediatric testing requirements may lead to the timely completion of pediatric studies to the benefit of pediatric patients with cancer. [ABSTRACT FROM AUTHOR]
