NCT ID: NCT05663671 Not yet recruiting - Ulcerative Colitis Clinical Trials

Evaluate Established Anti-DEFA5 mAbs Diagnostic Efficacy and Safety in IBD

Start date: June 1, 2023
Phase:
Study type: Observational

Investigators propose to validate efficacy and safety of the detection of DEFA5 in the diagnosis of the colonic IBD using longitudinal vs. cross-sectional studies of known patient clinical data to correlate with their endoscopy biopsy data. 30% of colonic IBD patients cannot be accurately diagnosed (CC vs. UC) in a timely manner even when a state-of-the-art classification system of combined clinical, endoscopic, radiologic and histologic tools are used. When the diagnostic classification for these two diseases is inconclusive, the condition is termed indeterminate colitis (IC). Here, the central medical challenge is the discrimination of IBD into the specific subtypes with high accuracy, as it greatly effects surgical care of patients. Diagnostic accuracy of IC into either authentic UC or CC is of utmost importance when determining a patient's candidacy for RPC-IPAA surgery, the standard curative surgical procedure for UC. Further, incorrect diagnosis and treatment carry potential morbidity from inappropriate and unnecessary surgery and costs. The success outcomes of RPC-IPAA surgery and convalescence depend on correct diagnosis. To address IBD diagnosis ambiguity and delays in IBD clinical settings, investigators developed a proteomic signature to discriminate between UC and CC patients that also will predict the outcome of IC patients for their eventual progress to either UC or CC. Our published data has shown robust evidence supporting presence of human alpha-defensin 5 (DEFA5) in areas of the colon mucosa with aberrant expression of apparent Paneth cell-like cells (PCLCs) or crypt cell-like cells (CCLCs), which identifies an area of colonic ileal metaplasia, consistent with the diagnosis of CC. DEFA5 bioassay discriminated CC and UC in a cohort of all IC patients with accuracy. A fit logistic model with group CC and UC as the outcome and the DEFA5 as independent variable differentiator with a positive predictive value of 96%. These findings were obtained solely from colectomy specimens for both the discovery and validation analyses. Investigators believe that use of endoscopy biopsies would be indifferent, which is the purpose of this prospective patient centered clinical study. Investigators propose to demonstrate that UC and CC, the two unsolved medical subtypes of pathology with no drugs for a cure, can accurately be distinguished molecularly by examining CCLCs-secreted DEFA5 in colonic endoscopy biopsies instantly. Our proposal is highly innovative, as it highlights the robustness of DEFA5 and its clinical relevance to IBD is both in science and the anticipated impact, as investigators seek to better understand difficulty to determine 'subtypes" and translate that to improve diagnosis, treatment, clinical outcomes, and quality of life for patients and the realm of clinical care. DEFA5 immunoreactivity in colonic endoscopy biopsies could be a rapid potential diagnostic signature to resolve IC into authentic UC and CC with a first clinic endoscopy biopsy. IC is likely to be eliminated for good.

NCT ID: NCT05653791 Active, not recruiting - Ulcerative Colitis Clinical Trials

Early Intestinal Ultrasound in Predicting Treatment Response to Filgotinib in Ulcerative Colitis

STEER
Start date: October 1, 2022
Phase:
Study type: Observational

Objective disease assessment in inflammatory bowel diseases at the time of treatment initiation and during follow-up has become gold standard. However, biomarkers, such as C-reactive protein and fecal calprotectin, fail to provide information on disease extent, location or complications. Repeated endoscopic assessments are performed to evaluate mucosal response to treatment, though associated costs, availability, invasiveness and patient preference are considerable limitations. Recently, intestinal ultrasound (IUS) has gained significant momentum as a non-invasive, easily accessible and low-cost alternative for objective assessment. Accordingly, the ECCO-ESGAR guideline recognizes IUS as a potential tool for the diagnosis and for the monitoring of IBD. Our study aim is to evaluate the change in intestinal ultrasound parameters (as measured by B-mode and SWE at baseline and week 4) to predict endoscopic response and remission as defined by the follow-up endoscopy and measured by the Mayo endoscopic subscore and the UCEIS during treatment with filgotinib

These patients were initially treated with VDZ. VitD3 supplementation was defined as 400IU/d vitD3 supplementation during the first infusion of VDZ and continued throughout the follow-up period. Disease activity was assessed using the modified Mayo score.

NCT ID: NCT05649332 Not yet recruiting - Burn Wound Clinical Trials

Study to Evaluate the Performance and Safety of the Medical Device Argogen

Start date: May 1, 2023
Phase: N/A
Study type: Interventional

A wound, i.e., a break in the skin, can result from several reasons. Pressure ulcers (also called pressure sores, bed sores and decubitus ulcers) are localized damage to the skin and underlying soft tissue usually over a bony prominence or related to a medical or other device, occurring as a result of intense and/or prolonged pressure or pressure in combination with shear. Burn wounds result from traumatic injuries to the skin or other tissues primarily caused by heat, electrical discharge, friction, chemicals, or radiation. Burns are acute wounds caused by an isolated, non-recurring insult. The Medical Device Argogen® (adsorbing spray powder for exudates with silver ions) consists of silver zeolite powder, combining in a single physical form the adsorbing properties of the zeolite structure and the antimicrobial properties of silver. Its action is due to the porous structure of zeolite that actively absorbs and control wounds exudate, keeping clean and dry the environment of small skin lesions, as wounds, abrasions, minor burns and bedsores. The association with silver ions gives to the medical device the additional property of an antimicrobial effect. The present study is to confirm that in a population of men and women presenting minor burn wounds (superficial or superficial / deep partial thickness) or chronic pressure ulcers stage 2 or 3 - NPUAP Classification (partial-thickness skin loss with exposed dermis or full-thickness skin loss) the medical device already CE marked Argogen® (adsorbing spray powder for exudates with silver ions) safely attests its capacity to promote wound healing, evaluated as percentage (%) of subjects with objective signs of wound healing (evaluated by mean of VSS score reduction for burn wounds or PUSH tool score reduction for pressure ulcers), results observed after 2 and 4 weeks after the beginning of the treatment.
