Emerging data suggest that clinical trials suffer from under-reporting of demographic data and under-representation of minorities. Literature on diversity of dermatologic clinical trials is limited, warranting further research. Objective: The study aims to describe the demographic composition of dermatologic clinical trial participants in the U.S. for psoriasis, atopic dermatitis and acne vulgaris reported between 2014 and 2019. Study design: A systematic review of literature on psoriasis, atopic dermatitis and acne vulgaris phase 3 clinical trials published between 2014 and 2019. Data will be compiled from two sources?for studies conducted exclusively in the US, demographic data reported in the published articles and among international studies, descriptive analysis and summary for each clinical trial requested from study sponsors. Final data includes descriptive summaries from each clinical trial obtained from different sources. Participants: Dermatologic clinical trial participants, specifically from psoriasis, atopic dermatitis and acne vulgaris trials reported between 2014 and 2019 and enrolled in the US. Main Outcome Measures: Participant enrollment in the US measured by mean/median age of the participant pool and proportion by sex and race/ethnicity. Statistical Analysis: Collective data will be weighted for the total population across the clinical trials and descriptive data analysis using weighted study population will be conducted."

  string(1131) "The US population is rapidly diversifying, and according to the US Census Bureau?s 2014 National Projections report, more than half of the US population is projected to be represented by minority groups by 2044(L.Colby & Ortman, 2015). Existing literature supports that responses to and adverse events due to drugs, including dermatologic drugs(Taylor, 2002), can differ between population subgroups(Conforti et al., 2018; Ramamoorthy, Pacanowski, Bull, & Zhang, 2015). NIH and FDA policies and guidelines call for adequate inclusion of women and minorities in clinical trials and other clinical research(Health, 2001, 2017). However, despite federal efforts, emerging data suggest that clinical trials, including for dermatologic conditions, suffer from under-reporting of demographic data and under-representation of minorities(Charrow, Xia, Joyce, & Mostaghimi, 2017; Chen, Lara, Dang, Paterniti, & Kelly, 2014). There is limited literature on the diversity of clinical trials in dermatology, thus, additional and more detailed studies describing the current composition of dermatologic clinical trial populations are warranted."

We hypothesize that there is under-representation of racial/ethnic minorities among all clinical trials for psoriasis, atopic dermatitis, and acne vulgaris in the U.S."
