Rimegepant in Moderate Plaque-type Psoriasis
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.

Risankizumab Long-term Remission Study
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...

Role of Glucose Metabolism in Migration of Cutaneous Dendritic Cells in Psoriasis
Dendritic cells (DC) paly a key role in the induction and chronicity of psoriasis by capturing the antigenes and activating the T cell repsonse. This activation requires their migration from the cutaneous sensitisation site to the lymph nodes. This migration requires an important intracellular metabolic activity, with a strong involvmenet of glucdic metabolism. This activity is linked with the systemic activity. This study aims to compare the migration and the phenotypic and metabolic caracteristics of blood and skin DCs in patients with or without psoriasis and with or without type 2 diabetes,

Role of Insulin Action in Psoriasis Pathogenesis
The goal of this study is to collect more information from people with plaque psoriasis and to determine if insulin plays a role in the pathogenesis of psoriasis. The main question it aims to answer is if insulin action is preserved or even enhanced in psoriatic lesions despite insulin resistance elsewhere. Participants with plaque psoriasis will have punch biopsies taken of lesional and non-lesional skin after an overnight fast and then during an oral glucose tolerance test. Biopsy specimens will then be assessed for markers of insulin action.

Role of Intermittent Fasting in Psoriasis and Psoriatic Arthritis
Our study aims to determine whether intermittent fasting (IMF) is a valid method to improve psoriasis and psoriatic arthritis (PsA) disease severity and quality of life. Patients within OSU Dermatology with psoriasis and/or psoriatic arthritis will be enrolled in a dietary intervention for a 24-week period. A prospective, single-blind parallel group randomized control trial will include an IMF dietary intervention group and a standard routine diet group for a duration of 24 weeks. After the initial 12 weeks of the dietary intervention, patients will be followed for an additional 12 weeks to assess changes in their disease state and...

Safety and Efficacy of Capsule FMT in Treatment-naïve Patients With Newly Diagnosed Chronic Inflammatory Diseases
PURPOSE: The main purpose is to explore clinical efficacy and safety associated with capsule FMT (cFMT) performed in newly diagnosed, untreated patients with rheumatic and gastrointestinal chronic inflammatory diseases (CIDs). DESIGN AND METHODS: In this 1:1 double-blind, placebo-controlled, randomised, 12-month exploratory trial, 200 patients with at least one of 6 different diagnoses of CIDs fulfilling the study criteria will be enrolled at time of diagnosis. The patient groups are: rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), pulmonary sarcoidosis (PSar), Crohn's disease (CD), and ulcerative...

Safety and Efficacy of Fecal Microbiota Transplantation
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with...

Safety, Tolerability, PK, PD and Preliminary Efficacy of ONO-4685
This is an early phase study to assess the safety and tolerability of ONO-4685 in patients with psoriasis. In addition, the study will assess how the drug is distributed and eliminated by the body (pharmacokinetics) and how the drug affects the body (pharmacodynamics). This will be done by measuring the amount of drug in the blood and measuring other markers in the body that might have been affected by ONO-4685. The study will also look at preliminary information on whether ONO-4685 might be effective in treating psoriasis. The study will be split into three parts. Part A will assess a single dose of ONO-4685 in small groups of...
