NCT01537393
The purpose of this study is to determine if the 3-year graft failure rate following endothelial keratoplasty performed with donor corneas with a preservation time of 8 to 14 days is non-inferior to the failure rate when donor corneas with a preservation time of 7 or fewer days are used.
NCT01773889
This study will test the hypothesis that adding pegylated IFN (IFN)a-2b to denileukin diftitox improves the potential of denileukin diftitox alone to deplete regulatory T cells (Tregs) and will thereby boost tumor immunity in patients with advanced-stage epithelial ovarian cancers, enhancing treatment efficacy.
NCT00880360
This study tests whether denileukin diftitox will deplete regulatory T cells, boost tumor-specific immunity and treat epithelial ovarian cancer in patients who have failed, or who are ineligible for front line therapy.

NCT02678286
The primary objective of this study is to evaluate the analgesic efficacy of N1539 in subjects with acute moderate to severe pain following abdominoplasty surgery.
NCT00845182
Pioglitazone, a drug used in treatment of type 2 diabetes has been shown to improve insulin sensitivity in skeletal muscle, liver, and fat cells. Despite the beneficial effects of pioglitazone to improve insulin sensitivity and reduce cardiovascular disease in high risk type 2 diabetic patients, weight gain has been a limiting factor. Exenatide, another agent used for treatment of T2DM, improves glycemic control and promotes moderate weight loss. In this proposal we will examine the effect of combination therapy with pioglitazone plus exenatide on body weight, fat topography, beta cell function, glycemic control, and plasma lipid levels in subjects with type 2 diabetes mellitus compared to treatment with each drug separately. Assessment of beta cell function will be performed by measuring the maximal insulin secretory capacity using a maximal hyperglycemic stimulus combined with an intravenous arginine stimulus.
NCT01107314
In this study we hope to delineate the typical vasoactive mediator response of trauma patients to shock. We plan to assess serum levels of vasopressin and also catecholamines, angiotensin, and cortisol during resuscitation of trauma patients to delineate high risk populations for vasopressin deficiency.
NCT01572298
When a tooth or teeth are extracted, a defect in the bony ridge often forms. This loss of bone may make it impossible to place a dental implant. Guided bone regeneration procedures are used to re-establish a bone dimension sufficient to place a dental implant. The primary objective of the study is to determine whether there is any difference in the gain of horizontal alveolar ridge width following guided bone regeneration surgery using a combined autogenous/allogenic particulate bone graft versus a particulate allograft alone. Autogenous bone has historically been considered the gold standard for alveolar ridge grafting; however, other materials including allografts and xenografts have also been used with excellent results. This study evaluates the potential benefits, or lack thereof, for using a combined autogenous/allograft approach versus an allograft alone. The investigators will clinically evaluate the efficacy of this technique and determine the difference in bone formation between groups following healing at 5 months by observing bone growth relative to heads of the tenting screws placed horizontally in the locations of greatest defect in the alveolar ridge. A biopsy of the healed site will be taken at the time of implant placement. The null hypothesis is that there will be no difference in the amount of horizontal ridge width gain at 5 months post-grafting between the two different grafting materials (allograft alone versus allograft combined with autogenous bone). Furthermore, the null hypothesis is that histologically, the combination graft (MinerOss®/particulate autograft) will have a similar percentage of vital bone present at 5 months compared to the allograft-alone group (MinerOss®).
NCT02514772
The study objective is to identify potential safety risks of the transition from US-licensed Rituxan® or EU-approved MabThera® to GP2013 (proposed biosimilar product) as compared to continuous treatment with the originator product in terms of general safety and immunogenicity.
NCT00408694
This phase II trial is studying how well giving bevacizumab together with cisplatin, radiation therapy, and fluorouracil works in treating patients with stage IIB, stage III, stage IVA, or stage IVB nasopharyngeal cancer. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of nasopharyngeal cancer by blocking blood flow to the tumor. Drugs used in chemotherapy, such as cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving bevacizumab together with chemotherapy and radiation therapy may kill more tumor cells.
NCT02327013
The purpose is to determine the effect of vortioxetine treatment on ADHD symptoms in adult patients with ADHD in a 12 weeks study.
NCT01622348
The purpose of this study is to evaluate different dose levels of IMO-3100 compared to placebo administered for 4 weeks to patients with moderate to severe plaque psoriasis.
NCT00789958
RATIONALE: Drugs used in chemotherapy, such as capecitabine and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving more than one drug (combination chemotherapy) together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving capecitabine together with gemcitabine followed by capecitabine and radiation therapy works in treating patients with cholangiocarcinoma of the gallbladder or bile duct.
NCT00435942
The purpose of this study is to evaluate the safety and efficacy of the Relay thoracic stent-graft system to treat thoracic aortic aneurysms. Efficacy will be evaluated by the device-related adverse event rate of endovascular repair (via Relay Thoracic Stent-Graft) through 1-year. Safety will be evaluated by comparing major adverse events through 1-year in subjects treated with the Relay Thoracic Stent-Graft to those who underwent surgical repair. Long term follow-up is conducted through 5 years.
NCT00360971
RATIONALE: Growth factors, such as palifermin, may lessen the severity of mucositis, or mouth sores, in patients receiving radiation therapy and chemotherapy for head and neck cancer. It is not yet known whether palifermin is more effective than a placebo in lessening mucositis in patients receiving radiation therapy and chemotherapy for head and neck cancer. PURPOSE: This randomized phase III trial is studying palifermin to see how well it works compared to a placebo in lessening oral mucositis in patients undergoing radiation therapy and chemotherapy for locally advanced head and neck cancer.
NCT00231478
This 2 arm study will evaluate the efficacy and safety of a single intravenous injection of Kytril in preventing postoperative nausea and vomiting (PONV) in children. Patients will be randomized to receive a single dose of either 20 micrograms or 40 micrograms Kytril intravenously (iv) 15 minutes prior to the end of surgery with general anesthesia for tonsillectomy or adenotonsillectomy. The anticipated time on study treatment is \<3 months, and the planned sample size was 170 patients.
NCT02013258
Individuals with Prader-Willi syndrome (PWS) have been found to have a deficit of oxytocin-producing neurons and decreased oxytocin receptor gene function, so the purpose of this study is to determine if oxytocin (OT) administration will improve some of the aspects of Prader-Willi syndrome that are particularly troublesome for children and their families (the insatiable appetite and social behaviors). The research questions are: 1. Does intranasal oxytocin cause any side effects in children with PWS? 2. Does intranasal oxytocin administration alter appetite or behaviors in PWS?
