Enrollment of Participants From Marginalized Racial and Ethnic Groups: A Comparative Assessment of the STEADY-PD III and SURE-PD3 Trials.

ABSTRACT:

Background and objectives

Representation of persons from marginalized racial and ethnic groups in Parkinson disease (PD) trials has been low, limiting the generalizability of therapeutic options for individuals with PD. Two large phase 3 randomized clinical trials sponsored by the National Institute of Neurological Disorders and Stroke (NINDS), STEADY-PD III and SURE-PD3, screened participants from overlapping Parkinson Study Group clinical sites under similar eligibility criteria but differed in participation by underrepresented minorities. The goal of this research is to compare recruitment strategies of PD participants belonging to marginalized racial and ethnic groups.

Methods

A total of 998 participants with identified race and ethnicity consented to STEADY-PD III and SURE-PD3 from 86 clinical sites. Demographics, clinical trial characteristics, and recruitment strategies were compared. NINDS imposed a minority recruitment mandate on STEADY-PD III but not SURE-PD3.

Results

Ten percent of participants who consented to STEADY-PD III self-identified as belonging to marginalized racial and ethnic groups compared to 6.5% in SURE-PD3 (difference = 3.9%, 95% confidence interval [CI] 0.4%-7.5%, p value = 0.034). This difference persisted after screening (10.1% of patients in STEADY-PD III vs 5.4% in SURE-PD 3, difference = 4.7%, 95% CI 0.6%-8.8%, p value = 0.038).

Discussion

Although both trials targeted similar participants, STEADY-PD III was able to consent and recruit a higher percentage of patients from racial and ethnic marginalized groups. Possible reasons include differential incentives for achieving minority recruitment goals.

Trial registration information

This study used data from The Safety, Tolerability, and Efficacy Assessment of Isradipine for Parkinson Disease (STEADY-PD III; NCT02168842) and the Study of Urate Elevation in Parkinson's Disease (SURE-PD3; NCT02642393).

Project description:ImportanceRacial and ethnic disparities in clinical trial enrollment are unjust and hinder development of new cancer treatments.ObjectiveTo examine the association of race and ethnicity with clinical trial enrollment among women with endometrial, ovarian, or cervical cancer.Design, setting, and participantsThis retrospective cohort study used data from the National Cancer Database, a hospital-based cancer registry, and the Surveillance, Epidemiology, and End Results Program (SEER), a population-based cancer registry. Population-based race and ethnicity-specific proportions for each cancer site were derived from SEER. Participants included women with an endometrial, ovarian, or cervical cancer diagnosed from 2004 to 2019. Analyses were performed from February 2 to June 14, 2023.ExposureRace and ethnicity were categorized as American Indian/Alaska Native, Asian, Black, Hispanic (any race), Native Hawaiian/Pacific Islander, White, and other (not defined in the National Cancer Database).Main outcomes and measuresThe primary outcomes were the odds of clinical trial enrollment and representation in clinical trials compared with the US population. Multivariable-adjusted logistic regression was used to estimate odds ratios (ORs) and 95% CIs for associations of race and ethnicity with clinical trial enrollment within the National Cancer Database sample. Participation-to-prevalence ratios (PPRs) according to diagnosis period (2004-2011 vs 2012-2019) were calculated by dividing the race and ethnicity-specific percentage of clinical trial participants in the study sample by the percentage of racial and ethnic groups in SEER.ResultsAmong 562 592 patients with gynecologic cancer (mean [SD] age at diagnosis, 62.9 [11.3] years), 1903 were American Indian/Alaska Native, 18 680 were Asian, 56 421 were Black, 38 145 were Hispanic, 1453 were Native Hawaiian/Pacific Islander, 442 869 were White, and 3121 were other race and ethnicity. Only 548 (<1%) were enrolled in clinical trials. Compared with White women, clinical trial enrollment was lower for Asian (OR, 0.44; 95% CI, 0.25-0.78), Black (OR, 0.70; 95% CI, 0.50-0.99), and Hispanic (OR, 0.53; 95% CI, 0.33-0.83) women. Compared with the US population, White women were adequately or overrepresented for all cancer types (PPRs ≥1.1), Black women were adequately or overrepresented for endometrial and cervical cancers (PPRs ≥1.1) but underrepresented for ovarian cancer (PPR ≤0.6), and Asian and Hispanic women were underrepresented among all 3 cancer types (PPRs ≤0.6).Conclusions and relevanceIn this cohort of patients with gynecologic cancer, clinical trial enrollment was lower among certain minoritized racial and ethnic groups. Continued efforts are needed to address disparate clinical trial enrollment among underrepresented groups.

Project description:ImportanceUrate elevation, despite associations with crystallopathic, cardiovascular, and metabolic disorders, has been pursued as a potential disease-modifying strategy for Parkinson disease (PD) based on convergent biological, epidemiological, and clinical data.ObjectiveTo determine whether sustained urate-elevating treatment with the urate precursor inosine slows early PD progression.Design, participants, and settingRandomized, double-blind, placebo-controlled, phase 3 trial of oral inosine treatment in early PD. A total of 587 individuals consented, and 298 with PD not yet requiring dopaminergic medication, striatal dopamine transporter deficiency, and serum urate below the population median concentration (<5.8 mg/dL) were randomized between August 2016 and December 2017 at 58 US sites, and were followed up through June 2019.InterventionsInosine, dosed by blinded titration to increase serum urate concentrations to 7.1-8.0 mg/dL (n = 149) or matching placebo (n = 149) for up to 2 years.Main outcomes and measuresThe primary outcome was rate of change in the Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UPDRS; parts I-III) total score (range, 0-236; higher scores indicate greater disability; minimum clinically important difference of 6.3 points) prior to dopaminergic drug therapy initiation. Secondary outcomes included serum urate to measure target engagement, adverse events to measure safety, and 29 efficacy measures of disability, quality of life, cognition, mood, autonomic function, and striatal dopamine transporter binding as a biomarker of neuronal integrity.ResultsBased on a prespecified interim futility analysis, the study closed early, with 273 (92%) of the randomized participants (49% women; mean age, 63 years) completing the study. Clinical progression rates were not significantly different between participants randomized to inosine (MDS-UPDRS score, 11.1 [95% CI, 9.7-12.6] points per year) and placebo (MDS-UPDRS score, 9.9 [95% CI, 8.4-11.3] points per year; difference, 1.26 [95% CI, -0.59 to 3.11] points per year; P = .18). Sustained elevation of serum urate by 2.03 mg/dL (from a baseline level of 4.6 mg/dL; 44% increase) occurred in the inosine group vs a 0.01-mg/dL change in serum urate in the placebo group (difference, 2.02 mg/dL [95% CI, 1.85-2.19 mg/dL]; P<.001). There were no significant differences for secondary efficacy outcomes including dopamine transporter binding loss. Participants randomized to inosine, compared with placebo, experienced fewer serious adverse events (7.4 vs 13.1 per 100 patient-years) but more kidney stones (7.0 vs 1.4 stones per 100 patient-years).Conclusions and relevanceAmong patients recently diagnosed as having PD, treatment with inosine, compared with placebo, did not result in a significant difference in the rate of clinical disease progression. The findings do not support the use of inosine as a treatment for early PD.Trial registrationClinicalTrials.gov Identifier: NCT02642393.
