Filter by:Ulcerative colitis (UC) is a chronic inflammatory condition causing continuous mucosal inflammation of the colon, which is accompanied by episodes of bloody diarrhoea and abdominal pain. Both infliximab and adalimumab have been used with success for moderate-to-severe UC refractory to conventional therapy. More recently, golimumab, another anti-TNF antibody, has been added to the treatment armamentarium. In the multi-centre, double-blind, placebo-controlled PURSUIT trial, patients with moderate-to-severe UC randomized to induction therapy with golimumab (200-100 mg, or 100-50 mg at week 0 and 2) achieved clinical response, clinical remission and mucosal healing more frequent than patients randomized to placebo. In the PURSUIT maintenance trial, patients randomized to golimumab every four weeks (100 or 50 mg) maintained clinical response through week 54 significantly more often than patients randomized to placebo. Data on the use of golimumab in daily clinical practice are unavailable. The aim of the retrospective Belgian multi-centre BE-SMART trial is to evaluate the mid-term outcome of golimumab in patients with moderate-to-severe colitis. The primary endpoint will be steroid-free golimumab continuation at week 26. Secondary endpoints will include (steroid-free) clinical remission, (steroid-free) clinical response, (steroid-free) mucosal healing, (steroid-free) complete mucosal healing hospitalization-free survival, and colectomy-free survival.
The primary objective of this study is to observe the long-term safety of filgotinib in adults who have completed or met protocol specified efficacy discontinuation criteria in a prior filgotinib treatment study in ulcerative colitis (UC).
Leg ulcers are defined as wounds lasting for more than a month. They would receive 0.2% of the population of Western countries. In Europe, the cost per episode of leg ulcers is estimated at 6650 euros (10 000 euros for a foot ulcer). The cost of treatment of wounds would be 2 to 4% of the health budget. Infection is the most common complication of chronic wounds: in most cases, it results in delayed healing, at most, it can result in amputation or serious general complications Bacterial contamination of ulcers is constant. Over time for over 25 years, various studies have shown about relatively identical results. The bacteria are present in over 90% of the etiology of venous leg ulcers. These bacteria are divided into four most common classes: Staphylococcus aureus, Enterococcus, Streptococcus, Pseudomonas. The bacterial ecology changes over time. Indeed Staphylococcus aureus appears first, while the Pseudomonas is associated with ulcers lasting for several months. Anaerobic more difficult to find, are found in 30% of cases Cohabitation between leg ulcers and bacteria often without clinical consequence: These are the stages of infection and colonization. The infection is related to the proliferation of bacteria and their invasion into the skin, by increasing their virulence (virulence genes acquisition). The increase in the number of bacteria and the multiplicity of bacterial genera are one reason for the increased virulence of bacteria. When bacteria proliferate, because the host defenses are inadequate, or because there is a vascular disease which promotes the proliferation, clinical signs appear
Investigate the safety and effectiveness of the RelayPro Thoracic Stent-Grafts in subjects with thoracic aortic aneurysms (TAA) and penetrating atherosclerotic ulcers (PAU) of the descending thoracic aorta.
The purpose of this study is to describe the long-term safety risks in adult participants with moderate-to-severe ulcerative colitis who are treated with Simponi.
The cause of Inflammatory Bowl Disease (IBD) is not known, but studies from patients with IBD have found that these patients make unusually strong immune responses to their own intestinal tissues and to bacteria that normally live in the healthy gut. These overactive immune responses might result from an imbalance of T-lymphocytes, which are a type of white blood cell that recognize and respond to threats like infection or damaged tissues. In healthy tissues, a type of T-lymphocytes called T-regulatory cells control excess inflammation by preventing other T cells, called T-effector cells from responding. We believe that T-regulatory cells are somehow less active in IBD, resulting in damage to intestinal tissues by the T-effector cells. T-lymphocytes, including both T-regulatory and T-effector cells, are guided to different parts of the body by 'alpha4beta7-integrin' molecules. Vedolizumab or Entyvio works by blocking this homing molecule so that T cells do not reach the intestine, but stay in the blood where they cannot aggravate your IBD. This study will help in understanding how Vedolizumab helps to heal or decrease the symptoms of your Ulcerative Colitis. The effect of Vedolizumab on different types of T cells in the human intestine has not yet been studied. However, the investigators think that Vedolizumab will shift the balance of T cells in the intestine towards more healing T-regulatory cells and less damaging T-effector cells. The purpose of this study is to measure the different types of T cells in participants' blood and intestinal tissue before and during Vedolizumab treatment.
This study assesses the long-term safety and efficacy of adalimumab in pediatric subjects with ulcerative colitis.
The main aim of the study is to check for long-term side effects of Vedolizumab Subcutaneous (also known as Vedolizumab SC) in people with ulcerative colitis and Crohn's disease. Vedolizumab SC will be given as an injection just under the skin. This type of injection is called a subcutaneous injection or SC for short. Another aim of the study is to collect information on whether the participant's condition remains under control or improves during and after treatment with Vedolizumab SC. Participants who previously took part in studies MLN0002SC-3027 or MLN0002SC-3031 will be invited to visit the study clinic. At this visit, the study doctor will check if each participant can take part in this study. For those who can take part, participants will receive a subcutaneous injection of vedolizumab SC either once a week or once every 2 weeks. How often each participant receives vedolizumab SC will depend on their results from the previous study and on how active their condition is. Participants might be able to self-inject vedolizumab SC after being trained by the study doctors. During this study, the dose of vedolizumab SC might be increased for participants whose condition worsens. Participants will continue treatment with vedolizumab SC until it is approved in their particular country, the participant decides to stop treatment, or the sponsor stops the study. If the sponsor stops the study before vedolizumab SC is approved in all countries, the sponsor will make sure all affected participants will have access to vedolizumab SC outside of the study. After their final dose of vedolizumab SC, participants will visit the clinic 18 weeks later for a final check-up. Then, the clinic will telephone the participants 6 months after their final dose of vedolizumab SC to check if they have any health problems.
Phase III clinical trial, multicenter, controlled, randomized, double-blind, with two parallel groups (experimental and control). Both study groups will receive standard therapy currently available in treatment centers for diabetic foot ulcer (DFU). Associate with the standard therapy, it will be given the recombinant human Epidermal Growth Factor (rhEGF) to experimental group and in the control group, it will be given a formulation without pharmacological effect (placebo) in order to masking and control of intralesional application. Participants with type 1 and type 2 diabetes mellitus (DM) diagnosed with DFU for at least 4 weeks, treated in referral centers participating in the study, agreeing to participate after reading, understanding and signing of Informed Consent (IC); meet all the inclusion criteria; and presenting no exclusion criteria. The Informed Consent (IC) should be applied to potential participants, as recommended by the regulations and ethical consensus before beginning any procedure related to the clinical trial. In the early weeks, participants will be evaluated at the research centers by the study team (doctors and / or staff). The number of visits will be determined by the investigator, thus ensuring appropriate assistance to participants, and avoiding any complications with DFU. By meeting the eligibility requirements (inclusion and exclusion criteria), the participant will undergo a thorough evaluation of the DFU before the start of treatment. This assessment is precisely to classify the condition of the ulcer before treatment and provide relevant information for statistical analysis of the protocol. If eligible, the participant will be randomly set to treatment arm (placebo or rhEGF) and the administration of investigational product associated with predefined standardized outpatient therapy will be initiated. This administration occurs three times per week until the DFU is scarred, not exceeding 8 weeks of treatment (T.01 to T.08) .The study will be randomized and balanced according to the type and size of the DFU. This balancing is necessary to ensure that both treatment groups are homogeneous for participants under different conditions. All participants will be applied established standard therapy for the treatment of DFU. The objective is to provide regular care for healing and reduce possible bias in the efficacy analysis and product safety. After the treatment period (last dose of the experimental drug) the participant will start the follow-up period, with 16 weeks duration. The participant shall be subjected to weekly visits for ongoing assessment of DFU, however, according to the investigator, may result in unscheduled visits to assess local or general clinical events. After the monitoring period, the participant will be observed for 24 additional weeks, visits every 4 weeks (E.01 E.24 a) having beginning one week after the last visit of follow-up. This period is intended to assess possible events related to the efficacy and safety that can happen in the period, mainly for analysis of secondary endpoints.
