Abstract
Importance Clinical trials remain the cornerstone for determining the safety and efficacy of an intervention. A diverse participant pool in dermatology clinical trials is critical to ensure that results are generalizable among the patient population who will ultimately depend on the efficacy of the intervention. The Skin of Color Society hosted the inaugural Meeting the Challenge Summit: Diversity in Dermatology Clinical Trials in Washington, DC, from June 10 to 11, 2022. The summit was an interactive and collaborative effort to advance discussions regarding the need for broader inclusion of racial and ethnic minority patients in dermatology clinical trials. Observations The summit focused on 3 principal areas: (1) understanding the current clinical trials landscape; (2) breaking down patient, clinician, industry, and regulatory barriers; and (3) effecting change through a diversity-focused strategy. The program hosted thought-provoking panel talks and discussions with various stakeholder groups, including a keynote presentation from the family of Henrietta Lacks. Conclusions and Relevance Panel discussions and insightful presentations from physicians, industry leaders, community trailblazers, and patients fostered new collaborations. The summit provided recommendations and suggested strategies for future initiatives designed to increase the representation of minority individuals in dermatology clinical trials.

Abstract
Filaggrins are an important class of intermediate filament-associated proteins that interact with keratin intermediate filaments of terminally differentiating mammalian epidermis. They show wide species variations and their aberrant expression has been implicated in a number of keratinizing disorders. We have isolated a cDNA clone encoding human filaggrin and used this to demonstrate that the human gene encodes a polyprotein precursor containing numerous tandem filaggrin repeats. This structure is similar to that of mouse; however, the human filaggrin repeat is much longer (972 base pairs; 324 amino acids) and shows little sequence homology to the mouse protein. Also, data presented here reveal that the human filaggrin repeats show considerable sequence variations; such polymorphism is not found in the mouse. Furthermore, chromosomal mapping data revealed that the human gene is located at 1q21, indicating that the polymorphism is confined to a single locus. By peptide mapping, we define a short linker sequence within the human filaggrin repeat that is excised by proteolysis to yield functional molecules. Finally, we show by in situ hybridization that human filaggrin precursor gene expression is tightly regulated at the transcriptional level in terminally differentiating epidermis and that this represents a useful system in which to study intermediate filament-intermediate filament-associated protein interactions as well as disorders of keratinization.
