NCT01074125
This is a research study for people with high blood phosphorus levels who are on dialysis. This medical condition can cause weakening of the bones and damage other organs. This can lead to many health problems, and sometimes death. Phosphorus is in much of the food we eat, and is helpful to us in small amounts. Patients with kidney failure have trouble getting rid of the phosphorus eaten in food. Dialysis can help remove some of the phosphorus, but often patients must take a phosphate binder like PhosLo®, Renagel®, or Renvela® to bring the blood phosphorus levels back to normal. The purpose of this study is to see if KRX-0502 (ferric citrate) is safe and effective as a phosphate binder.
NCT01014754
The primary objective of this study is to determine any causative or associated factors for the development of Nephrogenic Systemic Fibrosis (NSF), Nephrogenic Fibrosing Dermopathy (NFD), or related diagnosis. Our primary focus will be on the previous administration of gadolinium to these patients, but we will also look at other postulated causes and risk factors. The secondary objective of this study is to assess tissue gadolinium (Gd) levels in five groups of subjects: * Those affected by NSF. * Those with normal kidney function who have undergone a medical imaging procedure using Gd-based contrast agent (GBCA) in the 2 years prior to a skin biopsy. * Those with normal kidney function who have never been exposed to GBCA and have had a skin biopsy. * Those on dialysis or with eGFR ≤ 30 ml/min/1.73 m2 who have had a medical imaging procedure using GBCA in the 2 years prior to skin biopsy. * Those on dialysis or with eGFR ≤ 30 ml/min/1.73 m2 who have never been exposed to GBCA and have had skin biopsy. We hypothesize that there is a correlation between the administration of Gd-containing agents usually associated with MRI procedures and the development of NSF in those with renal failure and some other predisposing condition. We also hypothesize that tissue Gd levels in those with NSF will be higher than in those who have been exposed to GBCA but do not have NSF. Of the two groups without NSF but with exposure to GBCA, we hypothesize that those with kidney dysfunction will have higher tissue Gd levels than those with normal kidney function. We hypothesize that in the two groups of subjects without exposure to GBCA, there will be no detectable levels of Gd, regardless of kidney function status.
NCT00282087
The purpose of this trial is to study the benefits of giving chemotherapy to women after they have had surgical resection of their primary disease and have no evidence of disease remaining(known as adjuvant therapy). The major objective of this study is to determine the progression free survival. The goal is to prevent relapse or recurrence of their uterine leiomyosarcoma.
NCT00731549
To evaluate the overall effectiveness of aripiprazole intramuscular (IM) depot as maintenance treatment in patients with schizophrenia.
NCT01497431
This randomized phase I trial studies the side effects and the best dose of Se-methyl-seleno-L-cysteine or selenomethionine in preventing prostate cancer in healthy participants. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of Se-methyl-seleno-L-cysteine or selenomethionine, two different types of selenium compounds, may prevent prostate cancer from forming.
NCT01133665
The purpose of this study is to study specific FcRIIIa polymorphisms and their correlation with clinical outcome in subjects treated with cetuximab and lenalidomide.
NCT00532779
The purpose of this study is to determine whether 2 doses of the combination of naltrexone SR and bupropion SR are safe and effective in the treatment of obesity.
NCT01864356
The purpose of this study is to evaluate the efficacy, safety and tolerability of multiple doses of subcutaneous NT100 vs placebo following in vitro fertilization (IVF) in women with a history of repeated IVF failures.
NCT01905891
The purpose of this study is to correlate pathological features from specimens in order to determine if this new molecular diagnostic technique can be used to detect risk of skin cancer.
NCT00412061
The purpose of this study was to evaluate whether everolimus 10 mg / day added to treatment with depot octreotide prolongs progression free survival compared to treatment with octreotide alone in patients with advanced carcinoid tumor.
NCT01338818
This study will evaluate the long-term safety of methylphenidate hydrochloride extended release in adults with attention deficit/hyperactivity disorder
NCT01716663
This is a prospective, multicenter, non-randomized observational study of subjects 18 years and older undergoing RF ablation with drug refractory recurrent symptomatic paroxysmal Atrial Fibrillation (AF).
NCT01696058
The overall objective of this study is to assess efficacy and safety of 12 weeks, once daily, orally inhaled co-administration of olodaterol 5 µg (delivered by the Respimat® Inhaler) and tiotropium (delivered by the Handihaler® as Spiriva Handihaler®), compared to tiotropium (Spiriva Handihaler®) monotherapy on lung function in patients with COPD.
NCT00170547
This protocol is to compare the immune response of different influenza vaccines given by two different routes of administration in healthy adults ages 18 to 64 years.
NCT00050505
The purpose of this study is to determine the safety and effect of diluting smallpox vaccine, making a larger number of doses in case smallpox is released into the environment. A total of up to 927 healthy adults between the ages of 32 and 70 years who were already vaccinated against smallpox (but not since 1989) will volunteer for this study for up to 34 weeks and receive different strengths of vaccine. Some subjects may participate for longer if they choose to be revaccinated because the first vaccination does not take. The vaccine will be given by making small cuts in the skin and putting the vaccine into these cuts. After the screening visit, volunteers will be followed through study visits and follow up phone calls. Blood will be collected during some study visits to look at the immune system (body system that fights infection) response.
NCT01438814
The aim of this study is to investigate the impact of the combination therapy of linagliptin and metformin at submaximal doses in reduction of Glycosylated haemoglobin (HbA1c) and metformin pre-specified gastro-intestinal (GI) side effects in treatment naive patients of with type 2 diabetes mellitus.
NCT01869270
Hypothesis: To study the natural history of Tay-Sachs disease and evaluate therapeutic interventions. This study is intended to work in collaboration with NCT00668187 "A Natural History Study of Hexosaminidase Deficiency." Because so few patients with Tay-Sachs disease present annually, we will maximize both research projects by enrolling patients in both studies. For this present study, we will perform retrospective medical record review to gather data. Through this medical record review, we will collect biomarker analysis results, neuroimaging report data, quality-of-life questionnaire data and ophthalmology exam findings. If the subject has undergone therapy or treatment, the results will be noted.
NCT01877395
The aim of the study is to document the safety and immunogenicity of Purified Vero Rabies Vaccine (VRVg) when given in a simulated post-exposure regimen, i.e. with co-administration of human rabies immunoglobulins (Imovax® Rabies). Primary Objectives: * To demonstrate that VRVg is non-inferior to Imovax® Rabies in terms of proportion of subjects achieving a rabies virus neutralizing antibody (RVNA) titer ≥ 0.5 international units (IU)/mL at Day 14. * To demonstrate that the observed proportion of subjects achieving an RVNA titer ≥ 0.5 IU/mL at Day 14 is at least 99%, with a lower limit of the 95% confidence interval (CI) of at least 97%. Secondary Objectives: * To assess the clinical safety of each vaccine after each vaccine injection when administered in a simulated post-exposure schedule. * To describe the geometric mean titer ratio (GMTR) between the 2 vaccine groups at Day 14.
