NCT00501215
Primary hyperparathyroidism (PHPT) is an endocrine disorder that disrupts calcium metabolism and has a broad range of clinical manifestations. With respect to the nonclassic, subjective symptoms that have been reported to be associated with PHPT, such as sleep disturbance, neurocognitive dysfunction, mood disturbance, fatigue, and decreased quality of life, there is a lack of objective data on the extent to which these symptoms are affected by parathyroidectomy. There have been reports of improvements in sleep in patients following parathyroidectomy, but these have been based solely on subjective sleep surveys. To date, there are no published studies on objective sleep evaluations of patients with PHPT. The overall goals of this protocol are to ascertain the feasibility of performing sleep studies on patients with PHPT, and to obtain pilot data on the effects of parathyroidectomy on those sleep studies. It is hypothesized that it will be feasible to evaluate sleep parameters in patients with PHPT in the M. D. Anderson Sleep Center. Towards testing this hypothesis, the specific aims are: Specific Aim 1: To assess the feasibility of using nocturnal polysomnography (PSG) to evaluate the primary outcome measure of total sleep time. Specific Aim 2: To assess the feasibility of using nocturnal polysomnography (PSG) to evaluate the secondary outcome measures of sleep architecture, arousal index, sleep efficiency, wake after sleep onset, and sleep onset latency in patients with PHPT. Specific Aim 3: To assess the feasibility of evaluating the secondary outcome measures of subjective sleepiness as tested with the Epworth Sleepiness Scale (ESS), and of sleep quality as tested with the Brief Sleep Disturbance Scale (BSDS) in patients with PHPT. Specific Aim 4: To assess the feasibility using a randomized "wait-list"-control design to assess the effects of parathyroidectomy on sleep measures obtained with nocturnal PSG.

NCT01044186
The purpose of this open-label, non-comparative, multi-center protocol was to further evaluate safety and to provide treatment with ICL670 to patients who had or were at risk of life threatening complications due to transfusional iron overload with a documented inability to tolerate any of the commercially available iron chelators due to severe toxicity rendering continued therapy either impossible or hazardous. Patients who were also ineligible for all on-going registration trials with ICL670 were included in the study. In exceptional cases, patients with a degree of iron overload which was not immediately life-threatening and who were ineligible for the registration trials were also enrolled provided they had a well-documented, sound justification for alternative chelation therapy.
NCT00488514
This study was designed to determine long-term safety of TREXIMET (sumatriptan/naproxen sodium) in adolescents for the acute treatment of migraine.
NCT00434213
This is a study designed to characterize the dermal response of DAYTRANA. Subjects will visit the study site over a period of approximately 14 weeks.
NCT01175382
The primary aim of this project is to evaluate the effectiveness of combined behavioral + drug therapy compared to behavioral treatment alone and drug therapy alone as a way to improve outcomes in the treatment of OAB symptoms in men. We hypothesize that combined therapy will result in better outcomes than either behavioral or drug therapy alone. The second aim is to compare two methods of implementing combined therapy: simultaneously as initial therapy vs. stepped therapy, in which therapies are combined following initial behavioral or drug therapy alone. The third aim is to examine the costs and cost-effectiveness of combined behavioral + drug therapy compared to behavioral or drug therapy alone.

NCT02121210
Primary Objective: To evaluate the immunogenicity of sarilumab administered as monotherapy. Secondary Objectives: * To evaluate the other safety aspects of sarilumab administered as monotherapy. * To assess the exposure of sarilumab administered as monotherapy.
NCT00642616
Examine the effects of TI in combination with an anti-diabetic regimen including inhaled insulin versus anti-diabetic treatment without inhaled insulin on lung function \& pulmonary safety
NCT01519167
The objective of this study is to evaluate the safety of dexmedetomidine in a pediatric population requiring non-intubated, spontaneous breathing, moderate to deep sedation (NI-MDS) for elective diagnostic or therapeutic procedures, expected to take more than 30 minutes.
NCT01026493
RATIONALE: Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide. work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with temozolomide may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of giving veliparib together with temozolomide and to see how well it works in treating patients with recurrent glioblastoma.
NCT01871519
The study objective is to collect and report 12-month outcomes pertaining to activities of daily living, quality of life, and safety parameters in a Medicare population to be treated with balloon kyphoplasty in the treatment of painful, acute, vertebral body compression fractures (VCFs) associated with either osteoporosis or cancer. The primary objective is to show statistically significant improvement from baseline in the four co-primary endpoints (SF-36v2, PCS, EQ-5D, NRS back pain and ODI) at 3-months; study success will be declared if the primary objective is met. New radiographic fractures, non-surgical management received, VCF-related healthcare resource utilization, and vertebral body height restoration data will also be collected.

In addition, the study was designed to evaluate the impact of a CNI-free regimen on evolution of cardiovascular parameters in de novo renal allograft recipients
NCT00342758
Early life exposures now appear to be important in modulation of the immune response and tendency to develop asthma. We plan to enroll a cohort of children at birth to study early life factors in the development of wheezing and respiratory illness during the first six years of life in Mexico City. In particular, we will consider the role of early diet (particularly antioxidant intake, lactation and obesity), infections, dust mite and cockroach antigens, traffic related air pollution, and environmental tobacco smoke. We will also consider the potential modifying effect of genetic predisposition with respect to the exposures of interest. Approximately 6,800 children will be enrolled at birth. The goal is to follow the cohort though age 6. To increase the number of expected cases of asthma, we will partially enrich the cohort for increased risk of asthma by virtue of having a parent with doctor diagnosis of asthma or allergies; the remaining cohort will not be enriched to preserve generalizability. Pregnant women enrolled in a prepaid health plan in Mexico City (the Insituto Mexicano de Seguridad Social, henceforth referred to as IMSS) will be screened for the study and invited to enrolled their newborns when they come for delivery at one of two IMSS hospitals. An initial home visit during the first three months of life will include assessment of environmental exposures and infant diet. Children will be followed through age six with yearly home visits, monitoring of acute lower respiratory illness during the first year of life and periodic review of the IMSS medical records. We have chosen Mexico City because of the relatively low rates of asthma in the face of prevalent exposures to factors that are thought to increase asthma risk in urban areas in the United States. These include dust mites, cockroach, airborne pollutants and social factors such as low income and young maternal age. This pattern suggests that protective factors may be operating in Mexico City that could shed light on the etiology of worldwide childhood asthma epidemic. Potential candidates include exposure to certain early infections that shift the developing immune system away from the pattern of allergic asthmatic response. We are also especially interested in potential protective effects of early nutrition. Exposure to ozone in this population is the highest in North American and thus antioxidant intake may be especially important. In order to evaluate these protective hypotheses, we will also collect information on risk factors believed to be related to increased risk of asthma in US cities such as allergens, traffic related air pollutants, and lower respiratory infection with respiratory syncytial virus.
