Filter by:This is a multicenter, Phase III, randomized, double-blind, double-dummy, parallel-group study to evaluate the safety, efficacy, and tolerability of etrolizumab compared with infliximab in treating participants with moderate to severe ulcerative colitis (UC) who are naive to tumor necrosis factor (TNF) inhibitors. Participants will be randomized in a 1:1 ratio to receive either etrolizumab 105 milligrams (mg) by subcutaneous (SC) injection once every 4 weeks (Q4W) + placebo (intravenous [IV] infusion at Weeks 0, 2, and 6, then once every 8 weeks [Q8W]) or infliximab 5 milligrams/kilogram (mg/kg) IV at Weeks 0, 2, and 6, then Q8W) + placebo (SC Q4W). Time on treatment is 54 weeks.
Diabetes is a multiorgan disease and considered a major health problem in different societies. One of the complications the pain particularly in the extremities resulting from a process known as diabetic foot ulcer. The diabetic patients are subjected to many complications because of foot ulcers, many of them like as chronic wound disease or pressure ulcers (bed sore). Routinely used medical measures for diabetic foot ulcers are depended to nursing care and take too long until pain relief. Among many tested materials and works for wound healing such as debridement, tissue oxygenation, and skin transplantation, platelet-derived compounds are allocated the pivotal position between investigators to tissue regeneration and shortening the wound healing process. Many of platelet components are procured from platelet rich plasma (PRP) from whole blood donation. Furthermore, it requires to an additional purification step to diminish the volume and facilitate handling in some studies. It means that platelet concentrates (PCs) may be obtained leading to more concentrated platelets in lower volume. Two types of granules in platelet is responsible for storage of many useful and different growth factors: dense or delta and alpha granules. Platelet-derived growth factors have the ability to growth and differentiation of numerous cells. Also, the antibacterial effect of these growth factors has been reported. To better efficacy and comfortable utilization of platelet, it is feasible to form the platelet gel and then apply on wound sites. This study is a double blind randomized controlled trial to evaluate the positive effects of umbilical cord blood-derived platelet gel in 244 patients with diabetic foot ulcers.
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.
Ulcerative colitis (UC) represents one of the major entities of idiopathic inflammatory bowel diseases which are defined as chronically relapsing inflammations of the gastrointestinal tract not due to specific pathogens. It is characterised by a superficial, continuous mucosal inflammation, which predominantly affects the large intestine. The clinical course is typically marked by periods of asymptomatic remission punctuated by unpredictable recurrent attacks. The symptoms of the patients are marked by persistent diarrhoea with severe faecal urgency and often incontinence, rectal bleeding, abdominal cramping and weight loss. Uncontrolled activation of mucosal effector T cells has been identified as the main pathogenic mechanism involved in the initiation and perpetuation of intestinal inflammatory reactions. Patients with moderate UC are initially treated with mesalazine, applied both orally and rectally. If symptoms do not improve, systemic corticosteroids are to be administered. Patients who do not respond to systemic corticosteroids may become eligible for treatment with a calcineurin inhibitor or an anti-tumor necrosis factor (TNF)α antibody. Alternatively, patients may have to undergo major colorectal surgery. Patients who do not adequately respond to these treatment strategies exhibit serious drawbacks. Colorectal surgery may result in a severely compromised quality of life. Therefore, patients with moderate or severe UC may significantly benefit from new therapeutic alternatives. The transcription factor GATA-3 is an interesting target for a novel therapeutic strategy in UC. GATA-3 is the key regulation factor of Th2-driven immune responses. It is indispensable for the differentiation and activation of Th2 cells, integrates Th2 signals, and induces Th2 cytokine expression. Results of a recent clinical trial in children showed that GATA-3 is involved in the pathogenesis of the acute phase of UC. The investigational product SB012 contains the DNAzyme hgd40 that targets GATA-3. By cleaving GATA-3 mRNA hgd40 reduces specific cytokine production and thereby reduces key features of mucosal inflammation. DNAzymes are completely generated by chemical synthesis, not by use of any living organism and are therefore not biological drugs. This study will evaluate the efficacy, safety, tolerability and pharmacokinetics of the topical formulation SB012 available in a concentration of 7.5mg/ml hgd40 in 30ml PBS once daily as a ready-for-use enema in patients with active UC.
The purpose of this study is to assess an iPhone application to increase adherence to maintenance medications in subjects with ulcerative colitis.
This is an open label study of subjects who have failed Protocol PGN-1300. Adult subjects (greater than 18 years old) who present with a mildly infected diabetic foot ulcer (IDSA criteria) having full thickness (i.e., through the dermis but not involving joint capsule, tendon, and bone) and have failed PGN-1300. Subjects must also provide informed consent and meet all other entry criteria to be enrolled and receive PluroGel PN.
This two-part, part 1: open-label extension (OLE) and part 2: safety monitoring (SM) study will examine the efficacy and safety of continued etrolizumab treatment in moderate to severe ulcerative colitis (UC) participants previously enrolled in etrolizumab Phase II/III studies. Participants with moderate to severe UC who were enrolled in the Phase II OLE study (GA27927 [NCT01461317]) or the Phase III studies (GA28948 [NCT02163759], GA28949 [NCT02171429], GA28950 [NCT02100696], GA29102 [NCT02165215], and GA29103 [NCT02136069]) were included. Participants from the Phase II OLE study or the Phase III studies who are not eligible or willing to receive etrolizumab in the OLE-SM study, and who have completed the 12-week safety follow-up period will be enrolled in Part 2. Part 1 of OLE-SM will continue for up to 9 years after the first participant is enrolled into the study. Following Part 1, participants will enter Part 2 for a period of 92 weeks.
The current trial examines the potential benefits of continuous 12 week treatment with Santyl, measured in terms of wound bed appearance. The visual appearance of granulation tissue will be recorded at each visit for the purpose of examining the relationship between wound bed appearance and progress towards healing. In support of this longer treatment regimen with Santyl, a recent animal study found that application of Santyl for 12 weeks was safe and well tolerated. Therefore, the present study is designed to test the hypothesis that daily treatment of diabetic foot ulcers (DFU) with Santyl for up to 12 weeks will result in more rapid development of granulation tissue than DFU treated with supportive care.
The aim of this study is to evaluate scintigraphic methods as objective factors for functional outcome in patients treated with ileal-pouch-anal anastomosis (IPAA). The gastrointestinal transit-time and the degree of evacuation are evaluated in relation to the functional outcome.
A disturbance in the diversity of gut bacterial composition could be linked to several immune mediated diseases including inflammatory bowel diseases (IBD). IBD can be classified into Crohn's Disease (CD) and Ulcerative Colitis (UC). Both these diseases occur from abnormal immune reaction to resident gut bacteria.The process of fecal microbiota transplantation (FMT) where fecal bacteria from a healthy individual is transferred into a recipient, has recently received attention as an alternative therapy for individuals affected with these life-altering diseases. In this study, the investigators will perform fecal transplantation on the subjects meeting inclusion criteria, to determine the efficacy and safety of this therapy in subjects with IBD (CD and UC) who are not responding to first line therapy, and are in a flare.
