128 Background: Sparse data exists on the diversity clinical trial enrollment in community settings. This information is important to ensure equity of care and generalizability of results. Methods: We conducted a retrospective cohort study of members of an integrated healthcare system diagnosed with invasive malignancies (excluding non-melanoma skin cancers) between 2013-2017 to examine demographics of the oncology population compared to those who enrolled in a clinical trial. Logistic regression was used to assess correlates of clinical trial participation, comparing general and screened samples to enrolled sample. Odds ratios were adjusted for gender, geocoded median household income, cancer type, and stage. Results: Of the 84,977 patients with a cancer diagnosis, N = 2606 were screened for clinical trial participation and consented, and of those N = 1372 enrolled. The percent of Latinx (25.8% vs 24.0%; OR 0.9? CI 0.72-1.05) and African American/Black (10.9% vs 11.1%; OR 0.92 CI 0.75-1.11) clinical trial participation mirrored that of the general oncology population, respectively using Non-Hispanic Whites as reference. Asian/Pacific Islander had equal odds of clinical trial enrollment (OR 1.08 CI 0.92-1.27). The enrolled population was younger than the general oncology population. Conclusions: This study suggests that in an integrated healthcare system with equal access to care, the clinical trials population is well representative of its general oncology population.[Table: see text]
