Active clinical trials for "Ulcer"

This study adopts a multicenter, randomized, double-blind, low-medium-high dose group and placebo parallel controlled clinical study design. After screening, patients with active ulcerative colitis who meet the inclusion criteria and do not meet the exclusion criteria will be randomized by 1:1:1:1 to Hemay007 400 mg BID group, 800 mg QD group, 600 mg BID group or placebo group, with proposed 72 cases in each group. After 12 weeks of double-blind inductive treatment period, the patients will enter the Hemay007 open treatment period of 12 weeks when Hemay007 600 mg BID will be used as the medication regimen. All randomized subjects who have received the investigational drug should be subjected to a 4-week observation after the end of treatment.

Diabetic foot ulcer is one of the most serious, most costly and at times life threatening complication of diabetes. The lifetime incidence of foot ulcer occurrence in diabetes is up to 25%. Despite the advent of numerous types of wound dressings and off-loading mechanisms, the ulcer healing rates in diabetes have remained dismally low. Hyperglycemia impairs the inflammatory, proliferative and remodeling phases of an ulcer. There are retrospective studies linking improvement of HbA1c to wound area healing rate. The investigators hypothesised that intensive glycemic control in a patient of diabetic foot ulcer improves the healing process. To explore this hypothesis, the investigators are conducting this randomized control trial with the primary aim of wound healing in patients of diabetic foot ulcer on either intensive glycemic treatment or conventional (pre-existing) glycemic treatment.

This study will employ two monitoring device prototypes. The devices are sensors containing accelerometers and gyroscope. The raw output data will be analyzed to determine when patients are moved or are repositioned in their beds. The data is captured within a modem which will correlate these movements with video recordings for interpretation by the research team. One sensor is wearable on the patient gown or sleepwear, and the other is placed underneath the frame of the hospital bed. The investigators propose a non-blinded trial with n=10 where all subjects will undergo the two devices. A video camera will be placed in each subject room for recording the repositioning events to correlate the monitor signals with the actual subject repositioning captured by the video. The goal of the trial is to validate the ability of each of the sensor prototypes to accurately detect when subjects are turned, in order to reduce stationary positioning which contributes to the incidence of pressure ulcers and to improve compliance with patient repositioning trials.

The purpose of this study is to investigate the accuracy of second generation colon capsule (C2) in evaluating colonic mucosal inflammation of ulcerative colitis patients, using conventional endoscopy as the gold standard.

The primary objective is to evaluate the clinical benefit of CureXcell® as adjunct to Standard of Care in the treatment of Chronic Venous Leg Ulcers. CureXcell® is a cell based therapy, containing activated homologous white blood cells prepared from donated healthy whole blood. A total of 252 patients will be randomized to receive either CureXcell® or Placebo.

Patients have a diabetic foot ulcer that is older than 4 weeks and has been treated with physician-selected standard of care treatment such as debridement, hydrogel or saline irrigation, primary dressing, and offloading will be randomized into one of two groups, the Standard of Care (SoC) or APIC-PRP + SoC. APIC-PRP has high level of platelets that produce growth factors that can help in wound healing.

The purpose of this study is to determine whether prophylactic injection therapy reduces recurrent bleeding rate for duodenal ulcers which has the endoscopic stigmata of recent bleeding.

Clopidogrel causes significantly less peptic ulcer disease (PUD) and ulcer bleeding than low-dose aspirin in general population. However, clopidogrel is not safe enough for gastrointestinal (GI) mucosa in patients who had past history of aspirin-associated ulcer or ulcer bleeding. Aspirin plus proton pump inhibitor (PPI) is superior to clopidogrel alone in preventing recurrent ulcer bleeding in these high risk patients. This study is to compare the ulcer healing rate and ulcer bleeding at 12 weeks in patients with aspirin-associated PUD when they take PPI (rabeprazole 20 mg/day) to treat their PUD and simultaneously take aspirin or clopidogrel for their cardiovascular (CV) prevention. Two hundred patients will be randomly assigned rabeprazole (20 mg/day) plus aspirin (100 mg/day) or rabeprazole (20 mg/day) plus clopidogrel (75 mg/day) for 12 weeks. The primary end point is treatment success (ulcer healing rate). The secondary end point is incidence of ulcer bleeding within 12 weeks. If rabeprazole plus aspirin in not inferior to rabeprazole plus clopidogrel in the incidence of ulcer healing and ulcer bleeding in the healing phase,PPI plus aspirin rather than PPI plus clopidogrel will be recommended during acute ulcer healing in patients who need antiplatelet therapy for their CV prevention.

The aim of the current study is to replicate the COXA-0508-258 study in a multicenter, US setting, using a lower dose of ASA. It is expected that this study will not only confirm the results of the 258 study but show that the incidence of UGI ulcers on celecoxib is significantly less than on traditional NSAIDs and the incidence of UGI ulcers on celecoxib increases with the addition of ASA, but still is lower than traditional NSAIDs plus/minus ASA. This 7-day study is designed to compare the incidence of gastroduodenal ulcers associated with celecoxib 200 mg QD and low dose aspirin 81 mg QD and with naproxen 500 mg BID plus low dose aspirin 81 mg QD in healthy adults(50-75 years of age).

Herpes virus type 2 (HSV-2) infection - as a cofactor of human immunodeficiency virus (HIV) transmission - can be targeted by anti-herpetic specific drugs, either as a continuous prophylactic treatment during its asymptomatic shedding phase, or as an episodic treatment during clinically-apparent genital ulcerations. The main objective of this trial will be to demonstrate that acyclovir treatment given during clinical episodes (primary infection or recurrences) can reduce genital shedding of HIV, thereby contributing to a reduction of HIV infectiousness of dually infected individuals (HIV+/HSV+).
