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.
Prospective memory is the ability to implement an intention to the future (e.g. remember to take medication, attend a scheduled meeting), and has receive little attention in addiction. The investigators propose that prospective memory plays a critical, yet unrecognized, role in major human behavior change such as that required in addiction treatment. This study will determine the preliminary efficacy of prospective memory training in improving memory and executive functions while reducing illicit drug use in methadone patients. Participants will be randomly assigned to one of three conditions: an experimental memory training program or one of two comparator memory training programs.
This randomized pilot clinical trial studies how well circuit, interval-based aerobic and resistance exercise works in targeting metabolic dysregulation in stage I-III breast or prostate cancer survivors. Circuit, interval-based aerobic and resistance exercise may help to improve cardiovascular fitness, weight loss, healthy lifestyle behaviors, and muscle strength in breast or prostate cancer survivors.
The investigators' central hypotheses predict that the handheld spirometry device will be feasible for inpatient and at-home use, and is equally efficacious at determining lung function when compared to traditional, bedside spirometry measurements. To test these hypotheses, the investigators propose the following specific aims: Specific Aim 1: Determine the correlation of SpiroPD handheld spirometry measurements with bedside Koko spirometry lung function. Hypothesis: Correlation between the two lung function tests will be substantial for both hospitalized and ambulatory patients. Specific Aim 2: To determine the feasibility, adherence, and preliminary management efficacy of home SpiroPD testing. Hypotheses: (1) Patients will demonstrate substantial adherence to daily home spirometry testing; (2) medication adherence will increase significantly in patients who are adherent to daily home spirometry testing; (3) acute care utilization will decrease significant in adherent patients.
The purpose of this study is to evaluate the safety and tolerability of ATA188 as a monotherapy in Parts 1 and 2, to determine the recommended Part 2 dose (RP2D) of ATA188 as monotherapy in Part 1, and to evaluate the effect of ATA188 treatment on clinical disability, as assessed by confirmed Expanded Disability Status Scale (EDSS) improvement at 12 months in Part 2 in participants with progressive forms of multiple sclerosis (MS) (primary progressive multiple sclerosis [PPMS] and secondary progressive multiple sclerosis [SPMS]).
The purpose of this study is to investigate the use of an all-ceramic dental crown material to restore the abutment teeth of partially-edentulous patients who need removable partial dentures (RPD). The outcomes of the treatment group (all-ceramic crowns) will be compared to a similarly-treated control group whose RPD abutment teeth are restored using conventional metal and metal-ceramic crowns. Primary outcomes of interest include crown survival, abutment tooth survival and RPD survival.The null hypothesis is that at the conclusion of the study there will be no differences in outcomes between the two groups. All dental treatment, including dental hygiene and periodontal care, fillings, crowns and RPD fabrication will be provided by predoctoral dental students in the University of Kentucky College of Dentistry student clinics. Students treating the subjects will be supervised by licensed, technique-calibrated faculty specialists. Following the completion of dental treatment, enrolled subjects will be clinically re-evaluated by investigators at 6 months, and at annual intervals thereafter for 5 years following RPD delivery.
The goal of this protocol is to transfer autologous peripheral blood mononuclear cells (PBMCs) transduced with genes encoding a chimeric antigen receptor (CAR) that recognizes epidermal growth factor receptor variant III (EGFRvIII) tumor-specific antigen into patients with recurrent glioblastoma (GBM) following stereotactic radiosurgery (SRS). The CAR used is targeted to a tumor-specific mutation of the epidermal growth factor receptor, EGFRvIII, which is expressed on a subset of patients. Normal PBMCs derived from patients with GBM are genetically engineered with a viral vector encoding the CAR and infused directly into the patient's tumor with the aim of mediating regression of their tumors. Despite our CAR being targeted to a tumor specific antigen, given the prior toxicity using CARs that were not targeted to tumor-specific antigens, the investigators elected to begin with very low doses of cells. Enrollment on this study was suspended in April 2020 while an amendment to reduce the anticipated number of participants was under review and approved. The decision to terminate the study was made in January, 2021 to shift toward the next iteration of a related CAR T cell trial.
Deep brain stimulation (DBS) of different brain nuclei is a treatment for multiple brain disorders. The subthalamic nucleus (STN) and globus pallidus have been used to treat advanced Parkinson's disease for a long time. The ventral intermediate nucleus of the thalamus is an effective target for treating essential tremor patients. STN and the internal segment of the globus pallidus are useful targets for treating dystonia. To achieve this optimal electrode localization, many centers perform electrophysiological mapping of the target nuclei using microelectrode recording (MER). This way they can achieve precise localization of the electrode. During the mapping procedure, microelectrodes are passed through the target nuclei, and the electrical neuronal activity is observed and recorded. The surgical team can identify the precise location of the target nuclei and its borders according to the typical activity of its neurons. This study will compare the activity of neurons in several DBS targets before, during and after sedation with propofol, remifentanil and dexmedetomidine. The goal is to understand the effects of anesthetics on the neuronal activity in these targets, allowing us to choose the most appropriate sedation protocol to use during implantation of DBS electrodes in deep brain structures (bearing in mind that each structure may have a different optimal protocol).
The investigators propose an efficacy study (i.e., do salad bars work under controlled conditions in naturalistic settings) to test whether introducing salad bars in elementary, middle, and high schools that have never had salad bars affects students' FV consumption and waste during lunch. A cluster randomized controlled trial will test new salad bars against controls for 6 wks, with/without an additional 4-wk marketing phase .
This randomized pilot clinical trial studies how well preventive education works in decreasing caries formation in pediatric patients with leukemia. Prevention education may have an effect on factors important in causing cavities in pediatric patients with leukemia.
This study is a follow up study for subjects with Ulcerative Colitis (UC) in stable remission designed to evaluate flexible dosing of CP-690,550.
