Assessing the Diversity of Participants in U.S. Colorectal Clinical Trials: a Systematic Review and Meta-Analysis

Research output: Contribution to conferencePosterpeer-review

Abstract

Purpose: Investigating diversity of participants in colorectal cancer clinical trials.

Methods: We conducted a systematic review and meta-analysis of clinical trials on CRC to assess trial representation. Relevant CRC articles were obtained using MEDLINE and Embase. Included studies had to meet the following criteria: evaluated the effect of an intervention for CRC, performed in the U.S., published or posted between January 1, 2018 – December 31, 2023, and written in English. Data, extracted in blinded/duplicate fashion, included information about age, race, sex, and ethnicity. A Participation-to-Disease Representation Ratio (PDRR) was generated from the data, allowing us to quantitatively assess the representation of subjects along with the prevalence of colorectal cancer. Outputs were assigned a score of ‘poor’, ‘fair’, or ‘good’ to denote the subgroup representation within each included CRC clinical trial.

Results: A total of 25 clinical trials met the inclusion criteria. Regarding race and ethnicity representation, 21 studies received a ‘poor’ rating, 4 received a ‘fair’ rating, and none received a ‘good’ rating. For sex representation, 9 studies received a ‘good’ rating, 7 received a ‘poor’ rating, and the remaining did not report sex.

Conclusion: CRC clinical trials in the U.S. predominantly overrepresented white populations while underrepresenting Asian, Black, and Hispanic populations. These findings highlight the need for more equitable representation in clinical trials to ensure that diverse populations benefit from medical research advancements.
