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.
BACKGROUND: Auto immune pancreatitis (AIP), a benign pancreatic disease has certain morphological forms which mimics pancreatic malignancy in radiological appearance. There is no singe diagnostic test which can accurately differentiate these two conditions. In the past, AIP accounted for up to 27% of Whipple resections performed for suspected adenocarcinoma. AIMS: To evaluate the efficacy of Secretin assisted Magnetic resonance cholangio pancreatography (MRCP) in differentiating AIP and pancreatic malignancy. METHODS: 100 patients suspected with AIP will be consented to participate in the study to undergo secretin MRCP in addition to their other standard investigations. Patients will be categorized as those with AIP and with pancreatic malignancy based on these results and will be followed. Follow up will eventually give the true diagnosis when patients with pancreatic malignancy undergo pancreatic surgery and their pancreatic tissue is examined by histopathologist. AIP patients will undergo steroid trial which will give the true diagnosis. The preliminary diagnosis results based on standard investigations with and without inclusion of secretin MRCP will be compared to the true diagnosis.
The purpose of this study is to determine whether sirolimus reduces the symptoms of cutaneous T-cell lymphoma (CTCL) and whether it causes any side effects.
Patients are being asked to take part because they have melanoma that has spread to other organs in their body (metastatic). As part of this study, patients will receive radiation therapy and an approved drug (Vemurafenib).
We hypothesize that the combination of natural cycle IVF or low dose gonadotropin injection combined with In Vitro Maturation (IVM) (Natural IVF/IVM) is a viable option for a selected population of infertility patients who cannot tolerate exogenous gonadotropins or are at risk of ovarian hyperstimulation syndrome.
This is an open label Phase 1 study of the Ad-PfCA vaccine designed to 1) provide reagents for the development and refinement of cell-mediated immunoassays for measuring the human immune response to candidate malaria vaccines (especially protective malaria vaccines such as DNA/Ad-PfCA where better assays are needed to identify the correlates of protective immunity) and 2) to provide a repository of antigen-specific PBMCs that can be used as positive and negative controls in cell mediated immunoassays.
This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug is effective in treating a specific cancer. "Investigational" means that sulindac is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not yet approved the use of sulindac for your type of cancer. Participants in this study must have undergone previous chemotherapy and achieved complete remission, which is the absence of disease activity in people with a chronic illness, in this case AML. Unfortunately, a significant number of patients with AML who achieve a complete remission with initial chemotherapy eventually experience a relapse, often within a few months. Previous research studies have demonstrated that a type of medication frequently used to treat inflammation, called a COX inhibitor, may suppress and kill leukemia cells. COX inhibitors work by blocking a class of proteins called COX proteins. Other commonly used COX inhibitors are ibuprofen and naproxen. For this study, the investigators are using a COX inhibitor called sulindac, which has been FDA approved and used to treat pain and inflammation for many years, and has also been studied in suppressing certain tumors of the gastrointestinal system. The main goal of this study is to determine whether sulindac can help participants remain in a state of complete remission following the initial course of chemotherapy for AML, and two cycles of chemotherapy that is standard of care for your cancer, called consolidation chemotherapy. During the course of this study, the investigators will also attempt to learn more about how COX inhibition suppresses the emergence of leukemia, at the molecular and cellular level, by studying the participants on this trial.
The purpose of this research study is to test which topical anesthesia: LMX4 (Lidocaine 4%) or BLT (Benzocaine 20%, Lidocaine 6%, and Tetracaine 4%) is more effective in reducing discomfort during treatment with the Fraxel DUAL 1550/1927 (Solta Medical, Hayward, CA). No studies have been done on the effectiveness of LMX4 versus BLT using the Fraxel DUAL, although individually LMX4, BLT, and the Fraxel DUAL have been studied extensively. The hypothesis is that there will be no clinical difference between the two topical anesthetics.
The purpose of this study is to treat children with severe, moderate, resistant or relapsing C. difficile infection and to determine the changes in the intestinal microbiome (all of the bacteria living in the intestines) in children receiving FMT for C. difficile infection. Data will be collected throughout the FMT procedure to determine effectiveness and to help standardize this procedure. Stool samples will be collected to look at the different bacteria that are in the intestines before and after FMT.
Methadone is effective for heroin addiction, but many methadone patients continue to use cocaine. High magnitude and long-duration voucher-based abstinence reinforcement, in which participants receive vouchers exchangeable for goods and services contingent on providing drug-free biological samples, is one of the most effective treatments for drug addiction and can maintain cocaine abstinence over extended periods of time. Our research on a model Therapeutic Workplace has shown that employment-based abstinence reinforcement, in which participants must provide drug-free urine samples to access the workplace and maintain maximum pay, can maintain cocaine abstinence and reduce drug-related HIV risk behaviors over extended time periods. Our next challenge is to disseminate employment-based reinforcement for the treatment of drug addiction. The investigators propose to develop, manualize, and pilot test a community-friendly Therapeutic Workplace intervention that can be implemented widely throughout the US and elsewhere. Methadone patients who use injection or crack cocaine during methadone treatment will be invited to participate (N = 58) and randomly assigned to one of two groups: Usual Care (control) group or Community Therapeutic Workplace group. As in our prior implementations of the Therapeutic Workplace intervention, Community Therapeutic Workplace participants will enroll in Phase 1 to initiate drug abstinence and acquire job skills. Participants who initiate abstinence and acquire job skills in Phase 1 will be hired into community workplaces with collaborating employers in Phase 2. During Phase 2, employment-based abstinence reinforcement contingencies will be implemented using procedures for workplace drug and alcohol testing overseen by the US Department of Transportation. Using this system, a national provider of Drug-Free Workplace Services will arrange random drug testing and employment-based abstinence reinforcement contingencies in which employees will be required to remain drug-free to maintain employment. The investigators hypothesize that participants in the Community Therapeutic Workplace group will provide more drug-free samples, and engage in fewer HIV-risk behaviors than participants in the Usual Care group. The study will provide vital information on the acceptability of the intervention to participants and employers, and provide preliminary data on the effectiveness of the investigators procedures to maintain abstinence and promote employment.
Rubidium myocardial perfusion PET is an imaging test used to diagnose patients with abnormal blood flow to the heart secondary to narrowing of the heart vessels. Phase analysis is a computer method that is applied after the PET test is done. It is used to determine when a region of the heart contracts relative to other heart regions in the heart beating cycle. Initial data suggest that regions of the heart with abnormal blood flow change the pattern of contraction from rest to stress conditions. That is, regions of the heart with abnormal blood supply become dyssynchronous when compared to the normal regions of the heart. This study will investigate whether phase analysis may aid the visual interpretation of rubidium myocardial perfusion PET studies by determining the areas of the heart that are not beating in synchrony with the normal heart regions. This information will be used as a proxy for poor blood supply. The gold standard will be coronary angiography by which the percent narrowing of the heart vessels is assessed.
