Over the past 2 decades, there has been a marked increase in globalization of randomized clinical trials (RCTs); many RCTs led by high-income countries (HICs) are now enrolling patients from upper middle–income countries (UMICs) and lower middle–income countries (LMICs).
1,2 Although enrolling diverse global populations promotes research collaborations and may improve access to novel therapies, ethical concerns have arisen regarding industry-led clinical trials in lower-resource settings. Several issues remain, including the population that benefits from the globalization of RCTs, potential exploitation of research participants in settings with less regulatory oversight, and whether novel therapeutics will be available in participating countries following completion of the RCTs.
