An Explorative Psoriasis Biomarker Study

An Exploratory, Single-center, Double-blinded, Healthy Volunteer Controlled Study to Characterize Psoriasis Patients and Explore Novel Biomarkers for the Treatment Response of Psoriasis With a Multimodal Patient Profiling Approach.

Plaque psoriasis may be an ideal model disease to explore potential therapeutic effects of immunosuppressive agents, given the easy accessibility of inflammatory lesions. In this study, the applicability of a systems dermatology approach is investigated in order to better assess the efficacy of psoriasis treatments at an early clinical stage. Up to this point, the clinical manifestation and regression of psoriasis is not yet sufficiently characterized with a multimodal state-of-the-art evaluation tool. The in-house developed 'DermaToolbox' enables the determination and subsequent integration of different diseaserelated biomarkers, including clinical, biophysical, molecular, cellular, and imaging markers as well as patient reported outcomes

Detailed Description

Psoriasis is a common skin disorder affecting up to an estimated 3% of the world's population. The most prevalent form of psoriasis, called psoriasis vulgaris or plaque psoriasis, is characterized by the presence of sharply demarcated erythematous plaques covered with white scales. These lesions can occur all over the body, but are most often seen on the extensor surface of the joints, nether regions and on the scalp. Patients can experience excessive itch, pain and sometimes bleeding of the lesions. Moreover, the visual appearance of psoriatic lesions can severely impact the patients psychological state and quality of life. An abundancy of different factors contributes to the pathogenesis of psoriasis. However, aberrant inflammatory reactions in the skin are thought to be the underlying cause. Excessive infiltration of immune cells in the skin and their interactions with cutaneous resident cells results in the hyper proliferation of keratinocytes and subsequent thickening of the epidermis. Indeed, more and more immunosuppressive biologicals targeting specific components of the immune system, like tumor necrosis factor alpha (TNFα), interleukin (IL-)17 and IL-23, have shown excellent efficacy in treating psoriasis Plaque psoriasis may be an ideal model disease to explore potential therapeutic effects of immunosuppressive agents, given the easy accessibility of inflammatory lesions and the good willingness of patients to participate in clinical studies. In this study, the applicability of a systems dermatology approach is investigated in order to better assess the efficacy of psoriasis treatments at an early clinical stage. Up to this point, the clinical manifestation and regression of psoriasis is not yet sufficiently characterized with a multimodal state-of-the-art evaluation tool. The in-house developed 'DermaToolbox' enables the determination and subsequent integration of different disease-related biomarkers, including clinical, biophysical, molecular, cellular, and imaging markers as well as patient-reported outcomes
