Résumé

PURPOSEIn October 2017, an ASCO, Friends of Cancer Research (FoCR), and US Food and Drug Administration (ASCO/FoCR/FDA) task force recommended that common eligibility criteria be modified to make trials more inclusive. We examined whether patterns of exclusions regarding patients with brain metastases changed over time in relation to these recommendations.METHODSTrial eligibility criteria were abstracted from ClinicalTrials.gov for phase I-III US-based interventional clinical trials for patients with advanced breast, colorectal, lung, or melanoma cancers from January 2012 to December 2022. Trials were examined to determine whether patients with brain metastases were not excluded, conditionally excluded (ie, excluded in some circumstances), or wholly excluded. An interrupted time series analysis with multinomial logistic regression was used to determine whether the ASCO/FoCR/FDA recommendations were associated with changes in brain metastases criteria.RESULTSWe evaluated N = 3,077 trials. Patients with brain metastases were not excluded in 506 trials (16.4%), conditionally excluded in 2,263 trials (73.5%), and wholly excluded in 308 trials (10.0%). In the postrecommendation period, we estimated a 68% increase in the odds of brain metastases not excluded compared with conditionally excluded (odds ratio, 1.68 [95% CI, 1.06 to 2.66], P =.03). The proportion of trials in which patients with brain metastases were not excluded increased (from 11.5% v 17.3%) and conditionally excluded decreased (from 82.3% to 75.2%, P =.03). We found no difference in the proportion of trials in which patients with brain metastases were wholly excluded (7.5% v 6.2%, P =.42). CONCLUSIONThe ASCO/FoCR/FDA task force recommendations were associated with a shift in patterns of brain metastases exclusion criteria from conditionally excluded to not excluded. These findings demonstrate that the cancer clinical trial community has begun to change the way trials are written to be more inclusive.
