Active clinical trials for "Ulcer"

This is a Phase I dose-escalation study of MDX-1100. patients with ulcerative colitis will be enrolled into one of four dose cohorts, to receive of MDX-1100 at 0.3, 1.0, 3.0 or 10mg/kg. Three to six patients will be enrolled at each dose level, starting at the lowest dose level, for a maximum of 24 patients to be enrolled into the study. The study is designed to establish the safety and tolerability of single doses of MDX-1100 administered in dose-escalating cohorts to patients with ulcerative colitis. Other study objectives include characterizing a pharmacokinetic profile and pharmacodynamic effects of MDX-1100 and determination of immunogenic response to MDX-1100.

In this trial we test the hypothesis that a probiotic containing Lactobacillus acidophilus and Lactobacillus rhamnosus is an effective therapy for patients with ulcerative colitis.

This study was designed to evaluate the clinical benefits and safety of OrCel in the treatment of venous ulcers. OrCel and standard care were compared to standard care alone. Standard care consisted of currently accepted compression therapy. Patients were treated for 12 weeks. Patients with healed ulcers were followed for an additional 12 weeks to assess durability of the healed wound.

This is a Phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of three different doses of topically applied telbermin in subjects ≥ 18 years old with diabetic foot ulcers. Approximately 160 adult subjects with Type 1 or Type 2 diabetes mellitus will be enrolled at approximately 40 investigational sites in the United States and Canada.

Ulcerative colitis (UC) is an acute and chronic inflammatory bowel disease, whose cause is unknown. However, it is widely accepted that bacteria living in the large bowel are essential for the development of the disease. Intuitively, therefore, a logical approach to treatment would be to use antibiotics. However, antimicrobial chemotherapy has been unsuccessful in managing acute colitis, and has had only limited benefit in long-term treatment. The failure of antibiotics in UC arises from the fact that no-one has tried to identify which bacteria are involved in causing disease, and equally importantly, nobody has targeted appropriate antibiotics to knock out the specific bacteria in question, in a systematic way. Despite this, increasing evidence implicates bacteria living on the lining of the bowel being involved in UC. Our aim, therefore is to identify bacteria colonizing the mucosal surface in the lower large intestine and to determine the antibiotic sensitivities of those the investigators believe to be particularly involved in the disease, such as enterococcit, peptostreptococci and enterobacteria. Because the investigators have already studied resistance to antimicrobial in many mucosal isolate, the investigators plan ot focus on using a combination of two antibiotics in this work. A controlled trial will test the benefit of using these antibiotics over a period of one month and then the patients will be followed up over a six month period. The investigators will be looking for significant long-term improvements, and a reduction in drug use following antibiotic therapy.

The objective of this study is to assess the efficacy and safety of adalimumab for the induction of clinical remission in subjects with moderately to severely active ulcerative colitis.

The purpose of this study is to evaluate the safety, tolerability and effectiveness of Thymosin Beta 4 administered topically in patients with Pressure Ulcers

Ulcerative Colitis (UC) is a life-long incurable disease with remissions and exacerbations. Inflammation confined to the rectum occurs in a quarter of patients and can be extremely hard to treat. Many medications have been tried in order to control the inflammation, but they do not always work. One of the newer medications is the immunosuppressing medication, tacrolimus that has been shown to be effective in UC when taken orally. Unfortunately, the oral use of this medication can have numerous serious side effects. In order to overcome these side effects, the use of topical rectal tacrolimus has been examined. Pilot studies in ulcerative proctitis (inflammation confined to the rectum) resistant to conventional therapies have demonstrated a clinical remission in 75% of patients and although the medication was well absorbed through the lining of the bowel, the levels in the blood were very low and no serious side effects were reported. The findings suggest that this preparation is indeed effective for inflammation in the distal bowel and that the method of administration reduces side effects. Further work, however, now needs to be undertaken to validate the original findings.

Chronic foot ulcers are particularly prevalent in patients with underlying diabetes mellitus. These ulcers are reported to be the leading cause of hospitalization among people with diabetes. The purpose of this study is to evaluate CureXcell® in treating chronic lower extremity ulcers in adults with diabetes mellitus. CureXcell® is a cell based therapy, containing activated homologous white blood cells prepared from donated healthy whole blood. A total of 280 patients will be randomized to receive either CureXcell® or sham.

The purpose of this research study is to: 1) Test the safety and tolerability of 2 different oral doses of SRT2104 in subjects with ulcerative colitis 2) Determine the amount of SRT2104 measured from a single blood sample in addition to colon and/or rectal tissue samples (biopsies) 3) Determine whether SRT2104 has any anti-inflammatory effect on the colon and/or rectum when taken orally for 8 weeks 4) Determine whether SRT2104 causes any detectable changes to specific biomarkers. A biomarker is a biological marker (or substance such as a protein) that is used as an indicator of changes in a biological state that corresponds to the risk or progression of a disease.
