Active clinical trials for "Ulcer"

The main purpose of this study is to evaluate the long-term efficacy of mirikizumab in pediatric participants with ulcerative colitis (UC) or Crohn's disease (CD). The study will last about 172 weeks and may include up to 44 visits.

The study will assess the efficacy and safety of oral MT-1303 compared to placebo at 12 weeks as the induction treatment in subjects with active mild to moderate ulcerative colitis (UC), as well as maintenance treatment with open-label MT-1303 for up to 36 weeks.

The purpose of this study is to assess the safety and preliminary efficacy of PalinGen® Flow for the treatment of chronic ulcers of the lower legs and feet.

This is a twelve-week single-center, randomized, double-blind, clinical study to evaluate the safety and efficacy of a folic acid wound treatment (FAWT) versus Placebo in the promotion of healing of chronic, early stage diabetic foot ulcer (ES-DFU) wounds. Male and female Veterans with type-2 diabetes mellitus and chronic ES-DFUs acceptable to the study inclusion/exclusion criteria will be considered for enrollment.

Approximately 20-40% of patients with ulcerative colitis (UC) are obese. The investigators have demonstrated that obesity adversely impacts disease course in patients with UC, leading to higher risk of persistently active disease, surgery, hospitalization, and treatment failure, particularly in biologic-treated patients. Intentional weight loss is effective in improving disease outcomes in patients with inflammatory arthritis, but there is limited data on its impact in UC. While dietary interventions for weight loss have limited efficacy and endoscopic bariatric interventions may be too invasive in patients with UC with active gastrointestinal symptoms, pharmacological weight loss with a highly effective oral agent may be a novel strategy to induce weight loss and augment the efficacy of biologic therapy in UC. Hence, the investigators are conducting a pilot, phase 2A, 22-week, randomized, placebo-controlled clinical trial of phentermine-topiramate in obese patients with active UC starting on a new biologic agent (infliximab, adalimumab, golimumab, vedolizumab). The overall objective is to (1) evaluate the efficacy, safety and tolerability of phentermine-topiramate, and (2) to assess the impact of pharmacological weight loss on clinical outcomes, inflammatory burden and biologic trough concentration in patients with UC. The central hypothesis is that phentermine-topiramate will be safe, effective, and well tolerated in patients with UC, and weight loss would achieve higher rates of clinical and biochemical remission, and higher biologic trough concentration.

In this FinUC study we are trying to find out the efficacy and safety of the Fecal microbiota transplantation (FMT) in newly diagnosed active ulcerative colitis patients. The study group with newly diagnosed active ulcerative colitis receive an FMT via colonoscopy from a tested general donor, frozen and thawed from a fecal bank at week 0 and at week 4 as an enema at the study nurse´s visit. The control group will be given colored water. The main aim of the FinUC study is to determine how the FMT change of the gut microbiota composition in newly diagnosed active ulcerative colitis patients. The other aim is to determine efficacy and mechanisms of fecal microbiota transplantation.

The aim of this clinical trial is to investigate the efficacy (by monitoring the wound size reduction of CVUs) and safety (by monitoring adverse events [AEs]) of three dose groups of the investigational medicinal product (IMP) allo-APZ2-CVU, topically administered on target wounds of patients with CVU compared to placebo.

The primary efficacy endpoint for this study is the proportion of subjects with complete closure of Target Ulcer during the 20-week Treatment Phase, which is assessed by the blinded independent evaluator.

This study is being conducted to evaluate the safety and effectiveness of using the PXL Platinum 330 System with riboflavin solution for performing corneal collagen crosslinking (CXL) for the treatment of previously untreated corneal ulcers. The PXL Platinum 330 System is a combination product consisting of an ultraviolet A (UV-A) 365 nm wavelength light source (PXL Platinum 330 Illumination System) and riboflavin (Riboflavin 0.23% PESCHKE-L Solution) administered in conjunction with the UV-A light as a photosensitizer. The PXL Platinum 330 System is intended to induce corneal collagen CXL to improve the biomechanical properties of the cornea by strengthening the corneal tissue in the anterior stroma. Corneal collagen CXL is performed by pretreating the cornea with riboflavin ophthalmic solution beginning 40 min before UV-A light exposure to saturate the corneal tissue with the riboflavin photosensitizer. The cornea is then irradiated with UV-A light (365 nm) at an irradiance of 18 mW/cm2 (5 seconds on, 5 seconds off) for 10 min. Exposure of the cornea to this UV-A light regimen after topical administration of riboflavin ophthalmic solution has been shown to induce CXL of the corneal collagen fibrils, with a resultant increase in tensile strength and diameter of the collagen fibrils. Clinically, CXL has been shown to stabilize the corneal curvature in eyes with progressive keratoconus, with no significant change in the refractive index of the cornea. Numerous reports and a few clinical trials have also shown benefit in aiding resolution of infective corneal ulcers.

The purpose of this study is to evaluate the efficacy and safety of JNJ-78934804 as compared to guselkumab and golimumab in participants with moderately to severely active ulcerative colitis who have had an inadequate initial response, loss of response, or intolerance to one or more approved advanced therapy.
