Improving clinical trial enrollment in minority racial and ethnic patients with gynecologic malignancy.

PURPOSE

Racial and ethnic minorities remain underrepresented in clinical trials . Underrepresentation of racial groups leads to the selection of therapeutic interventions that may not be representative of the population expected to use the medicine. This study evaluates the effectiveness of a set of implementation strategies to increase underrepresented patients in gynecologic cancer clinical trials.

METHODS

An interrupted time series analysis evaluating implementation strategies (pre-screening and fast-track referral) was conducted from January 2021 to May 2022. Descriptive analysis of gynecologic oncology patient screening and accrual was compared before and after intervention implementation.

RESULTS

During the study period (pre- and post-intervention), 26 patients were screened, and 9 patients enrolled in therapeutic gynecologic cancer clinical trials. Prior to the intervention, 7 patients were screened and 2 patients enrolled onto a clinical trial. Following the intervention, 19 patients were screened and 7 patients enrolled in a cancer clinical trial. Black patients comprised 13 of 19 (68.4%) of patients post-intervention compared to 1 of 7 (14.3 %) of patients screened pre-intervention (p < 0.05). All 7 patients enrolled post intervention were racial and ethnic minorities (non-Hispanic Black [4 of 7] and Hispanic White [3 of 7]) compared to no minority patients enrolled pre-intervention (p < 0.05). Screening increased 2.5-fold for all patients, and 5- fold for minority patients. Clinical trial enrollment increased 3.5-fold following intervention.

CONCLUSIONS

A combination of pre-screening and fast-track referral intervention in a racial and ethnically diverse urban academic hospital was associated with a significant increase in minority screening and enrollment. Structured strategies to overcome barriers to underrepresented racial and ethnic patient accrual in academic hospitals are urgently warranted.
