ABSTRACT

Introduction:

Clinical trials often have low enrollment of minorities, particularly African-Americans (AAs), which may limit the generalizability of research findings. Previously identified barriers to AAs recruitment include historical abuses leading to mistrust, communication issues with providers, socio-economic factors, and a lack of access to clinical trials. In a Historically Black College and University (HBCU) serving a primarily AA population at a large safe-net hospital, we evaluated the enrollment of eligible AA patients for a colorectal cancer (CRC) screening clinical trial. This was compared to the enrollment rates across other study sites.

Methods:

A large, prospective, multi-centered clinical trial to validate a blood-based test for early detection of CRC (PREEMPT-CRC) was initiated at a HBCU, where 84% of patients are AAs. To maximize study recruitment, culturally sensitive methods were employed including racially congruent recruitment staff as well as synchronized timing of consent/study procedures with preendoscopy COVID testing/clinic visits. Detailed information for all eligible subjects was recorded. Demographic and socio-economic data including census information for enrolled and not enrolled subjects were compared. The enrollment rate (defined as enrolled/eligible patients) over the first 6 weeks at the HBCU and that of the other study sites providing screening logs was analyzed.

Results:

The enrollment rate at the HBCU was 55% (44 out of 80 eligible patients;95% CI 43.5- 66.2%), compared to 49.8% (258 out of 518 eligible patients;95% CI 45.4- 54.2%) at the other 26 study sites. While age and gender of enrolled patients at the HBCU were comparable to other sites, the main difference was race at the HBCU the study participants were 79.5% AAs and 9.1% whites, while at the other sites the participants were 11.5% AAs and 82.8% whites (p< 0.001). At the HBCU, the demographic characteristics and socio-demographic data including income, marital status insurance status/type, and census tract median household income of the 44 enrolled and 36 notenrolled subjects were similar (Table 1).

Conclusion:

Contrary to conventional belief that AAs do not want to be involved in clinical trials, we find their enrollment is similar to a predominant white study population when offered the opportunity in a culturally sensitive setting. Future trials should consider including HBCU sites in order to attain adequate AA enrollment to improve the generalizability of research findings. (Table Presented).
