Participation of underrepresented minority children in clinical trials for Fragile X syndrome and other neurodevelopmental disorders.

The purpose of this study was to identify demographic data, motivational factors and barriers for participation in clinical trials (CTs) at the University of California Davis, MIND Institute. We conducted a cross-sectional survey in 100 participants (81 females and 19 males). The participants had high education levels (only 2% had not completed high school), a mean age of 44 years (SD ± 9.899) and had at least one child with a neurodevelopmental disorder. The diagnosis of Fragile X syndrome (FXS) had a significant association with past participation in CTs (p < 0.001). A statistical significance for age of diagnosis and participation in CTs was also found (z = -2.01, p = 0.045). The motivating factors were to help find cures/treatments for neurodevelopmental disorders and to relieve symptoms related to child's diagnosis. Factors explaining lack of participation, unwillingness to participate or unsure of participation were: lack of information/knowledge about the trials, time commitment to participation (screening, appointments, assessments, laboratory tests, etc.) and low annual household income. These results show that a portion of underrepresented minorities (URM) not participating in CTs are willing to participate and suggests that reducing barriers, particularly lack of knowledge/information and time commitment to trials are needed to improve recruitment.
