NCT00288275
Chemoresponse assays (lab test) measure the effect that chemotherapy treatment has on a patient's cancer cells in the lab. This test has shown success in a retrospective study in predicting how an individual patient's tumor will respond to a given chemotherapy and how treatment utilizing an agent that the test said that a patient's cells would be sensitive too corresponds to a longer progression free interval. This study will determine the ability of two tests used to predict the success of chemotherapy in recurrent, persistent, or refractory cancer of the ovaries, fallopian tube(s) or peritoneum by measuring how long patients live without progression.
NCT00457821
The purpose of this study was to evaluate the safety and tolerability of ivacaftor in patients with cystic fibrosis (CF) who were aged 18 years or older and have a G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective CFTR potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic AMP-dependent protein kinase A (PKA) activation.

NCT00521534
Background and Introduction: SDB is increasingly recognized as a co-morbidity with significant impact on overall health. The disorder has been implicated in the development of hypertension, atherosclerotic cardiovascular disease as well as arrhythmia, stroke and the progression of congestive heart failure. The disorder is prevalent among males, estimated to affect upto 24% of the general population. Its prevalence increases with age, and it is particularly prevalent among patients with congestive heart failure with the prevalence rising to 51% in that group. Interestingly, recent evidence points to a potential impact for treating sleep disordered breathing, on heart failure patients. At the same time, recent reports of a beneficial impact of atrial overdrive pacing on SDB, have stirred interest in a potentially effective and well tolerated non-pharmacologic means of therapy for this disorder. Particularly at a time when cardiac resynchronization therapy utilizing biventricular pacing has demonstrated significant impact on heart failure, the interplay between CHF and SDB pacemaker based therapy begs further exploration. The interdependence of potential positive impact on each entity needs to be elucidated for further research and refinement of therapeutic tools. Furthermore, this study aims to explore potential neurohormonal influence on and affection by each of these disorders. Specific Aims and Hypotheses: Specific Aim #1: To assess the effect of cardiac resynchronization therapy (CRT) with or without atrial pacing on SDB in patients with advanced CHF at 8 and 16 weeks after implementation of therapy. Hypothesis #1: Resynchronization therapy improves SDB, the effect may anticipate or lag improvement in heart failure. Atrial pacing has a beneficial effect in addition to CRT. Specific Aim #2: To explore the effect of CRT on cardiac neuro-hormonal activity in relation to its effects on CHF and SDB. Hypothesis #2: CRT neuro-hormonal modulation is a common path in its effects on SDB and CHF. Specific Aim #3: To assess prevalence of sleep disordered breathing (SDB) in patients with advanced congestive heart failure (CHF). Hypothesis #3: SDB is prevalent yet under recognized in this patient population. Research Design: This is an observational study with a built in double blinded prospective randomized interventional substudy of a potential confounder i.e. atrial pacing. All patients will receive CRT with defibrillator for clinical indications (CRT-D). Investigators other than the EP physicians as well as patients will be blinded to the pacing mode. After screening and a run in period of back up pacing a baseline polysomnogram (PSG) will be performed. Patients will be randomized between atrial overdrive or atrial tracking pacing modes for six months, all patients receiving CRT. Sleep studies will be performed at baseline and at three month intervals. Subjects: Patients referred for implantation of CRT -D will be recruited for this trial. Patients are included only if they are indicated for such a device on clinical grounds. Outcome Measures: 1.Sleep quality related Parameters:The following will be collected at times of each PSG: MAP-PSQI, PSG parameters of sleep quality and architecture, apnea hypopnea index, and oxygen saturation as well as biochemical markers of sleep efficiency. 2.Heart Failure Parameters: The following will be obtained at times of each PSG: Minnesota Living with Heart Failure Questionnaire, Clinical and echocardiographic measures of heart failure progression and biochemical markers of heart failure severity. Power Analysis: An improvement in SDB in both initial randomization arms is assumed, however we further assume the atrial overdrive arm will offer improvement over the atrial tracking arm of equal magnitude. An arbitrary estimate would be twenty percent improvement in atrial overdrive arm. The corresponding estimate is 40% improvement due to CRT. To achieve 0.80 power thirty four data sets need to be collected.

NCT00785369
The purpose of this study is to image pigmented skin lesions suspicious for melanoma with an imaging technology called in vivo reflectance confocal microscopy. This technology uses low intensity laser to image below the surface of the skin. The confocal images of the suspicious skin lesion will be examined. The goal of this study is to compare the results of the confocal image examination to the pathologic diagnosis of the skin lesion. The technique being evaluated in this study uses reflectance confocal microscopy in vivo. The term "in vivo" means in/on a living subject. In this study you will be the living subject and the confocal microscope will be placed on your skin to look at your skin lesion. The confocal microscope uses a weak laser light and a sophisticated lens to image the individual cells that make up the skin. Your lesion will be photographed with high resolution photography.

NCT00833248
The purpose of this phase 3B trial was to see how well a new trial drug (degarelix) works in terms of reducing the size of the prostate volume in prostate cancer patients who were scheduled to undergo subsequent radiotherapy for treatment of their prostate cancer. Prior to receiving radiotherapy, it is recommended that patients with intermediate to high risk prostate cancer are pre-treated with hormone therapy (so-called neoadjuvant therapy) which is known to reduce the size of the prostate and thereby decrease the required radiation field and enable a more safe and effective treatment. In this trial, participants were randomly selected (like flipping a coin) to receive either degarelix given alone or a standard hormone therapy (combination of goserelin and bicalutamide. The treatment was given for three months and the prostate size was measured by ultra sound at the beginning and at the end of the trial. The participants were required to come to the clinic for 5 or 6 visits during the three months.
