Filter by:This study learn how easily patients can use an educational tool that will be created for patients with melanoma and pre-existing autoimmune diseases who receive or will receive immune checkpoint inhibitor drugs. Patients will be asked their opinions about the design, accessibility, and content of the tool. Researchers will use the information collected to improve the educational materials that will help patients make future decisions about their treatment.
Pro-inflammatory cytokines are critically important drivers of inflammatory and autoimmune diseases and cytokine-targeted biologics have been transformative in the treatment of several inflammatory and autoimmune diseases. As the diversity of approved cytokine-targeted biologic therapies grows, it will become increasingly important to stratify patients on the basis of specific genetic or disease biomarker phenotypes to ensure that patients receive the appropriate cytokine-targeted biologic, at the appropriate dose, and at the appropriate time. This project aims to explore patterns of pro-inflammatory cytokine/chemokine expression within normal versus (i) psoriatic, (ii) eczematic, (iii) ichthyotic human skin, as well as in human and mouse models of skin inflammation, with the objective of identifying cytokine response profiles ('cytokine fingerprints') that will provide a molecular basis for (a) the stratification of patients into disease subtypes that (b) enable cytokine-directed biologics to be targeted towards patients that are most likely to benefit from them. The investigators anticipate that 'cytokine fingerprinting' will aid in the selection of the most appropriate biologics in patients that are most likely to benefit from such therapies.
Psoriasis is a chronic inflammatory disease with a multi-factorial etiology which affects the epidermis and dermis. It affects around 1-3% of the general population and its most frequent form is plaque psoriasis (around 80-90% of the overall psoriasis cases). Psoriasis severity and extension are usually measured through 2 scores: Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA). Periodontitis is a chronic inflammatory disease mediated by the biofilm and with a multi-factorial etiology. Its manifestation entails the destruction of the periodontal tissues surrounding the teeth; the final stage of disease is characterised by tooth loss. Periodontitis severity and extension are usually evaluated through surrogate variables such as: BoP (Bleeding on Probing), PPD (Probing Pocket Depth) e REC (Recession). Both diseases present overlapping genetic and pathophysiologic features, as well as common risk factors (e.g. genetic polymorphisms, smoking habit, obesity, diabetes etc.). miRNAs are small non-coding molecules involved in the regulation of various biologic processes thanks to their interaction with mRNAs. Active inflammatory processes either in the oral cavity or at a systemic level tend to alter the concentration of salivary miRNAs. No study so far has ever profiled the levels of specific salivary miRNAs in patients with psoriasis and periodontitis. Some case-control studies highlighted a higher prevalence of periodontitis in patients with psoriasis when compared to healthy controls. Nonetheless, epidemiological data regarding periodontitis prevalence in patients with psoriasis are lacking; moreover, few data are available regarding the relationship between the severity of psoriasis and the severity of periodontitis, together with the effect of common risk factors (e.g. diet, obesity, physical activity, sleep quality etc.).
The purpose of this study is to assess the effect of a biologic drug targeting the Interleukin (IL)-17 pathway (secukinumab) on brain plasticity and examine whether the plastic changes correlate with the improvement of perception of well-being, itch, and pain in participants with psoriasis.
Hashimoto's disease (HT) and psoriasis (PsO) have a significant impact on patient's quality of everyday life, and early diagnosis is critical for the symptoms management and prognosis. There is evidence that HT and PsO share common metabolic pathways that relate to their pathogenesis, and are affected by dietary and lifestyle factors. Previous studies have identified potential metabolic biomarkers, although the small number of studies hamper their validation. Of note, most studies are not longitudinal thus do not capture the metabolic fluctuations in response to disease progression or dietary changes. Thus, the purpose of this study is to identify metabolic biomarkers of HT and PsO and study the role of epigenetic factors (diet and lifestyle) on the involved metabolic pathways . In addition, a comparative analysis of the disease-related quality of life (QoL) will be performed in relation to dietary changes to unravel possible links between the QoL and the associated metabolic pathways in HT and PsO.
This is a two-arm open-label study to evaluate the clinical and immunogenetic responses of patients with plaque or guttate psoriasis to treatment with guselkumab.
Although the newly developed biologics (drugs derived from living cells cultured in a laboratory) are highly effective in controlling psoriasis, all the biologics should be continuously injected to suppress recurrence of the disease. In this regard, the observation in the phase II clinical trial conducted by us (Laboratory for Investigative Dermatology at the Rockefeller University) was groundbreaking that just a single dose of anti-IL-23p19 antibody (risankizumab, trade name: Skyrizi, study drug in this clinical trial) administration produced disease clearance up to 66 weeks in 46% (6 of 13) of patients. However, there is a lack of understanding about immune regulation in human skin induced by anti-IL-23p19 antibody injection, and there is a need to conduct a psoriasis clinical trial for single-cell sequencing immune cells in human psoriasis skin before and after anti-IL-23p19 antibody administration, and to correlate regulatory immune cell alterations with clinical disease progression. The overall objective of the clinical trial is to study regulatory immune cell alterations induced by anti-IL-23p19 antibody administration in psoriasis patients who achieve long-term disease clearance off drugs.
The purpose of this study is to examine the use of a new investigational medication for the treatment of moderate plaque-type psoriasis. The study medication is rimegepant, an orally administered small molecule competitive inhibitor of the calcitonin gene-related peptide (CGRP) receptor. This medication, rimegepant, has been approved by the FDA under the trade name Nurtec for the treatment of acute migraine. However, rimegepant has not been studied in the treatment of moderate plaque-type psoriasis and is investigational for this indication.
This is a multicenter, randomized, double-blind, placebo-controlled study in subjects with moderate to severe plaque psoriasis.
This is a single-center, open-label study. Approximately 30 qualified subjects will be enrolled in a study lasting 20 weeks which investigates the effect of Enstilar used in combination with Otezla to treat psoriasis.
