Shifting Sociodemographic Characteristics of a Phase I Clinical Trial Population at an NCI-Designated Comprehensive Cancer Center in the Southeast

Abstract

Racial and ethnic minority populations are consistently under-represented in oncology clinical trials despite comprising a disproportionate share of a cancer burden. Phase I oncology clinical trials pose a unique challenge and opportunity for minority inclusion. Here we compared the sociodemographic characteristics of patients participating in phase 1 clinical trials a National Cancer Institute (NCI)-designated comprehensive center to all patients at the center, patients with new cancer diagnosis in metropolitan Atlanta and patients with new cancer diagnoses in the state of Georgia. From 2015 to 2020, 2325 patients (43.4% female, 56.6% male) consented to participate in a phase I trial. Grouped self-reported race distribution was 70.3% White, 26.2% Black, and 3.5% other. Of new patient registrations at Winship Cancer Institute (N = 107 497) (50% F, 50% M), grouped race distribution was 63.3% White, 32.0% Black, and 4.7% other. Patients with new cancer diagnoses in metro Atlanta from 2015 to 2016 (N = 31101) were 58.4% White, 37.2% Black, and 4.3% other. Race and sex distribution of phase I patients was significantly different than Winship patients (P
