There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Stent placement may help reduce symptoms caused by the tumor. Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment for cholangiocarcinoma. It is not yet known whether stent placement and photodynamic therapy using porfimer sodium are more effective than stent placement alone in treating cholangiocarcinoma. PURPOSE: This randomized phase III trial is studying stent placement and photodynamic therapy using porfimer sodium to see how well they work compared to stent placement alone as palliative treatment in treating patients with stage III or stage IV cholangiocarcinoma that cannot be removed by surgery.
The purpose is to evaluate safety and feasibility of the use of Rituximab as an adjunct to standard therapy (plasmapheresis + steroids) for patients with thrombotic thrombocytopenic purpura (TTP). This includes evaluating the rate and type of treatment failure.
The purposes of this study are the following: 1. To further characterize and quantify both CSF-1 and colony-stimulating factor-1 receptor (CSF-1R) expression from additional tumor specimens, specifically, tumors of high grade and from metastatic sites. 2. To assay using Enzyme-Linked ImmunoSorbent Assay (ELISA) sandwich monoclonal antibody methodology, CSF-1 expression in the peritoneal fluid and blood from patients with endometrial adenocarcinomas. 3. Using immunohistochemistry, to evaluate the presence of staining for CSF-1 and CSF-1R from additional patients with endometrial adenocarcinomas, especially of high grades and from metastatic sites. 4. To determine the extent of cytokine, specifically CSF-1, but also interleukin-1 (IL-1), IL-6, and granulocyte-macrophage colony-stimulating factor (GM-CSF), production, in endometrial carcinoma cells in primary cell culture. 5. To determine the responsiveness of epithelial cells on estrogen and antiestrogen binding, to determine if CSF-1 production is mediated, in these cells, by estrogen receptor binding, or alternative pathways of intracellular/cell-cell signal transduction. 6. The ultimate objective of these experiments is to characterize CSF-1 expression from benign and tumor cells in order to identify steps in the CSF-1 activated signalling pathways that may represent potential targets for therapy.
Our proposal is to study infants in the Neonatal Intensive Care Unit (NICU) who are undergoing a heel stick for blood sampling, a standard procedure in patient care. Currently, these infants do not get any pain relief for this procedure. Several recent clinical studies have shown the usefulness of nitrous oxide (laughing gas) for treating pain for minor procedures in children 0 to 18 years, but these effects have not been exclusively studied in the newborn and infant populations. Animal studies have questioned the anti-nociceptive (pain-blocking) effect of nitrous oxide in very young animals. It is unclear if this also applies to humans. The reason for this difference may be due to an immaturity of the neural pathways that modulate pain in the very young. The purpose of this study is to investigate whether or not nitrous oxide has an analgesic (pain-relieving) effect in infants undergoing minor procedures in the neonatal period (less than 3 months).
The purpose of this study is to determine the amount of Aerosolized Liposomal-Nitro-20 (S)-Camptothecin (L9NC) in a patients blood and tumor.
The purpose of this study is...to assess whether placing a substance abuse intervention for HIV+ methamphetamine users within an HIV medical care setting improves rates of follow-up on referral to treatment by primary care physicians; reduces drug use and sexual risk behaviors more than treatment-as-usual; and increases rates of adherence to HIV medication regimens.
Ionizing radiation produces cancer cell death by creating high levels of reactive oxygen species (ROS), such as superoxide and hydrogen peroxide, in irradiated cells. Cancer cells are preferentially affected by ROS. The investigators, therefore, propose that interfering with the detoxification of ROS will make radiation more toxic to cancer cells. Several cellular mechanisms exist to detoxify ROS, and glucose metabolism plays an important role in many of these mechanisms. The investigators propose that interfering with glucose metabolism will sensitize cancer cells to radiation. The investigators' central hypothesis is that 2DG will sensitize cancer cells to ionizing radiation by inhibiting the use of glucose to detoxify reactive oxygen species produced by radiation. As an initial step to evaluate this hypothesis, the investigators have designed this phase I study.
To measure the speed of bacterial eradication from the respiratory tract after administration of azithromycin or telithromycin.
Hepatic artery infusion (HAI) with oxaliplatin (OX), systemic 5 fluorouracil (5FU), and leucovorin (HAI/OX/FU) will be implemented using an interventional radiology technique to obviate the need for initial major surgery (catheter placement) in patients who have unresectable liver metastasis from colorectal cancer. The study goal is to reduce tumor size to make possible a complete resection of all lesions. Secondary goals are to reduce or eliminate the complexity usually associated with HAI, to accomplish most or all of the treatment as an outpatient, to reduce costs, and to avoid the hepatotoxicity associated with HAI/floxuridine (FUDR). Oxaliplatin has been selected because of its ease of use, known toxicology, and established efficacy in colorectal cancer.
The purpose of this prospective randomized study is to evaluate the risks and benefits of using bimodal analgesia, (i.e. Narcotics and NSAIDS) vs Narcotics alone post long bone fracture.
