Intersectionality Between Country, Gender and Funding in Authorship for Phase III Trials Presented at the ASCO Annual Meeting 2022.

Purpose Multiple disparities have been recognized in the area of location, gender, and funding for leadership in oncology clinical trials. Understanding their intersectionality is crucial to be able to formulate policies and actions, to ensure research is representative of the global oncology community. Here, data from phase III trials presented at the ASCO Annual Meeting of 2022 (ASCO22) were analyzed.Methods The location of institution, gender of lead and senior authors, and funding source for solid tumor phase III trial abstracts presented at the ASCO22 were analyzed. World Bank analytical grouping version 2021-2022 was used to describe regions and countries as high (HIC), upper-middle (UMIC), lower-middle (LoMIC), and low-income (LIC).Results Across 239 phase III abstracts, lead and senior authors respectively represented HIC institutions in 83% and 85%, UMIC in 13% and 12%, and LoMIC in 4% and 3%. No authors worked in LICs or sub-Saharan Africa. Women accounted for 29% of lead and 23% of senior authors. This distribution persisted across regions, with women as lead authors ranging from 19% (UMIC) to 31% (HIC), and as senior authors from 7% (UMIC) to 25% (HIC). Industry funded 62% of trials, academia 17%, and others 15%; 6% lacked funding. Industry funding was highest in HIC trials (66% for lead and senior authors), followed by UMICs (55% lead, 53% senior) and LoMICs (11% lead, 0% senior). Industry-sponsored trials were proportionally equally represented among female and male senior authors (63% each).Conclusion There is marked intersectionality in leadership of oncology clinical trials presented at the world's largest oncology conference.
