Active clinical trials for "Ulcer"

The aim of this study is to determine if early angiographic embolization can forestall recurrent bleeding in selected high risk ulcers after their initial endoscopic control; to validate prospectively the investigators proposed in selecting high risk ulcers for recurrent bleeding in spite of maximal endoscopic control and profound acid suppression using high dose intravenous infusion of proton pump inhibitor; to characterize the nature of bleeding arteries in severely bleeding peptic ulcers and determine the efficacy of angiographic embolization in the prevention of recurrent bleeding and to establish safety profile of angiographic embolization as an early elective treatment to bleeding peptic ulcers.

This study is designed to evaluate the efficacy and safety of tofacitinib (CP-690,550) in patients with moderate to severe ulcerative colitis who have failed or be intolerant to one of following treatments for ulcerative colitis: oral steroids, azathiopurine/6-mercaptopurine, or anti-TNF-alpha therapy.

The DUAL-1 study is designed as a multicenter, double-blind two-period study with an initial fixed 16-week Period 1, followed by a Period 2 of variable duration. All patients completing Period 1 will continue on their original randomized treatment into Period 2, until the last randomized patient has completed Period 1. Patients will be randomized in a 1:1:1 ratio (macitentan 3mg: macitentan 10mg: placebo). The primary objective is to demonstrate the effect of macitentan on the reduction of the number of new digital ulcers in patients with systemic sclerosis and ongoing digital ulcers. Other objectives include: the evaluation of the efficacy of macitentan on hand functionality and DU burden at Week 16 in SSc patients with ongoing DU disease. the evaluation of the safety and tolerability of macitentan in these patients. the evaluation of the efficacy of macitentan on time to first DU complication during the entire treatment period.

This study is an open label, long-term extension study for subjects with moderate to severe ulcerative colitis designed to evaluate long term therapy of CP-690,550.

The LeucoPatch™ study goal is to investigate whether the fully autologous growth factor-containing dressing LeucoPatch™ has a positive effect on healing rates of diabetic foot ulcers. The study seeks to gather data for comparison with previous data from similar wounds (historical controls). By subgrouping of the treated wounds (similar to the historical controls used) an assessment of which of the patient and wound-related factors that might indicate a beneficial effect of LeucoPatch™ is sought.

The primary objective of this study is to evaluate the safety and preliminary performance of EASH dressing for 4 weeks followed by AQUACEL® dressing for 4 weeks on venous leg ulcers.

This study is an open-label extension (OLE) trial to evaluate the safety and tolerability of etrolizumab in participants with moderate to severe ulcerative colitis (UC) who were enrolled in the Phase II Study ABS4986g (NCT01336465) and meet the eligibility criteria for entry in the OLE study.

The purpose of this study is to determine the efficacy of TAK-438, once daily (QD), compared to lansoprazole in patients with duodenal ulcer.

The aim of this study is to assess the relationship between microscopic Geboes index of inflammation and clinical course of ulcerative colitis in patients treated with infliximab. The investigators propose to test the hypothesis if infliximab is able to induce histological remission and then change the clinical course of ulcerative colitis.

To determine the dose or doses of PF-00547659 that will be the most effective to improve or halt the disease symptoms in patients with moderate to severe ulcerative colitis.
