The purpose of this study is to evaluate of the long-term safety and efficacy of KCT-0809 in dry eye patients with Sjögren's syndrome.
Peripheral nerve blocks with local anesthetics (LAs) have become an integral part of postoperative pain management particularly for patients undergoing major limb procedures such as such as Total Knee Arthroplasty (TKA). And while postoperative pain management in patients with a history of chronic opioid use may be difficult with systemic opioids because of opioid tolerance, there is anecdotal evidence suggesting that these patients may also be less responsive to LAs. Preliminary data from pre-clinical animal study show that there is a decreased LA potency in blocking sciatic nerve in opioid tolerant rats. And the decrease in LA potency is reversed by the knock-down of the beta4 subunits of Voltage-gated sodium channels along the sciatic nerves, suggesting the opioid induced intrinsic changes in the peripheral nerve as an underlying mechanism for opioid induced loss of LA potency. Study Goals: To determine the extent to which the changes in beta4 subunits of voltage-gated sodium channels are reflected in surgical patients. Experimental Design / methodology: This is a prospective, double-blind, active treatment controlled study. TKA Patients who receive nerve blocks will be grouped according to their history of pre-operative opioid use, and then tested for local anesthetic use for nerve block. Synovial tissues will also be collected for the analysis of beta4 subunits. Subject population: Patients who are scheduled for TKA procedure, and agree to receive peripheral nerve block for postoperative pain control, will be recruited for the study. Patients will participate in one of the three study groups: opioid naive, opioid history and opioid tolerant. 30 patients for each group with a total of 90 patients will be recruited. This study will not only determine the extent to which the preclinical findings are reflected in clinical patients, but also identify the underlying mechanisms that may suggest strategies for more effective post-operative pain management in the growing population of opioid tolerant patients
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. PURPOSE: Randomized phase III trial to compare the effectiveness of cyclosporine plus methotrexate with cyclosporine plus T cell depletion for prevention of graft-versus-host disease during peripheral stem cell transplantation in patients who have advanced leukemia or lymphoma who are eligible for transplanted peripheral stem cells from a donor.
RATIONALE: Methylphenidate may decrease side effects of radiation therapy. It is not yet known if methylphenidate is effective in improving quality of life in patients with primary or metastatic brain tumors. PURPOSE: Randomized phase III trial to determine the effectiveness of methylphenidate in improving quality of life in patients who have brain tumors and are undergoing radiation therapy.
This study was designed to find dose response and as extension in treatment of GW823093C.
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiolabeled monoclonal antibodies, such as yttrium Y 90 ibritumomab tiuxetan, can find cancer cells and carry cancer-killing substances to them without harming normal cells. Giving rituximab together with combination chemotherapy and yttrium Y 90 ibritumomab tiuxetan may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving rituximab together with combination chemotherapy and yttrium Y 90 ibritumomab tiuxetan works in treating patients with relapsed follicular non-Hodgkin lymphoma.
Objective: The objective of the study is to evaluate the ability of current vancomycin dosing strategies to attain the pharmacodynamic target of an area under the curve (AUC) to minimum inhibitory concentration (MIC) ratio greater than 400:1 for patients with a suspected or documented Staphylococcus aureus infection. Primary Outcome: The primary outcome is the percentage of vancomycin dosing regimens that achieve AUC:MIC ratio > 400 on the first occurrence of vancomycin use in patients with a suspected or documented S. aureus infection at The Nebraska Medical Center. Secondary Outcomes: 1. To assess the probability that vancomycin AUC:MIC ratios obtained from The Nebraska Medical Center patients exceed a therapeutic threshold using S. aureus MICs from isolates obtained from The Nebraska Medical Center. 2. Using MIC data from the TRUST Study database (large national surveillance database) and the vancomycin AUC data obtained from TNMC patients, perform a Monte Carlo analysis that will assess the probability of achieving a therapeutic vancomycin threshold with a large number of isolates.
This study will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083A vaccine given as a three-dose vaccination course at 3, 5 and 11 months of age.
The purpose of this clinical trial is to test the effectiveness and safety of a new anti-diabetes drug (Cyclo-Z) for the prevention and treatment of Type 2 diabetes. This study will determine dose-dependent efficacy and safety of this new drug for the treatment of human diabetes. The Food and Drug Administration has granted approval for the use of this investigational product to be used in a study [FDA approval (Investigational New Drug) IND #: 61,897]. This new drug is thought to work by increasing the amount of zinc in your body, which in turn should improve your sugar metabolism. If this study successfully proves that Cyclo-Z is effective for the treatment of diabetes and is without significant side effects, a large, multi-center study of diabetic patients will then be performed.
A study to evaluate the efficacy of lenalidomide as maintenance therapy after completion of first-line combination chemotherapy in patients with mantle cell lymphoma (MCL) who are not candidates for transplantation and have achieved partial response (PR) or complete response (CR). This study was prematurely terminated by the sponsor in light of new unpublished data that rendered the current design of the study no longer clinically relevant. A study design with the control arm of no active treatment was no longer appropriate. The termination of the trial was not based on any safety concerns in the study.
