NCT01410097
Obesity is associated with physical disability through both direct pathways (e.g., lower extremity pain, insufficient muscle strength) and indirect pathways (obesity-related comorbidities and inflammation). Furthermore, diabetes, a major obesity-related health condition, is associated with increased risk of disability and accelerated declines in physical and cognitive function. The investigators preliminary data suggest that intentional weight loss improves physical function, and there is strong circumstantial evidence that it would also benefit cognitive function. To evaluate the role of intentional weight loss on physical and cognitive function, the investigators propose an ancillary study to the on-going Look AHEAD (Action for Health in Diabetes) trial. Look AHEAD is a multi-center, randomized clinical trial to examine the effects of a 4-year lifestyle intervention designed to achieve and maintain weight loss through decreased caloric intake and exercise in overweight or obese men and women aged 45-74 years with type 2 diabetes. The investigators propose to add validated and well-established measures of physical and cognitive performance to the year 8 follow-up visit - during the trial's weight maintenance phase - in \~1000 participants at 4 of the 16 Look AHEAD field sites (Colorado, Memphis, Pennington and Pittsburgh). The specific aims of this ancillary study are: 1) To determine the long-term effects of a lifestyle intervention designed to achieve and maintain weight loss on physical function; and 2) To determine the long-term effects of a lifestyle intervention designed to achieve and maintain weight loss on cognitive function. In addition, the investigators hypothesize that in the intervention group, larger initial weight loss, better weight loss maintenance, and higher physical activity will be associated with better physical and cognitive function. The investigators also hypothesize that in the control group weight loss will be associated with worse physical and cognitive function than in those who are weight stable or who have gained weight. The number of obese older adults is rising rapidly and there are few data to guide an evidence-based clinical response to their management. The results of this study will provide the first direct evidence of the role of long-term intentional weight loss on the maintenance of physical and cognitive function in older obese adults with diabetes. Since this study is being done as an ancillary study to an on-going trial it can be done in a timely and cost-efficient manner.
NCT00085098
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy alone is as effective as chemotherapy plus radiation therapy in treating germ cell tumor. PURPOSE: This randomized phase III trial is studying radiation therapy alone to see how well it works compared to chemotherapy and radiation therapy in treating patients with newly diagnosed primary CNS germ cell tumor.
NCT00523042

NCT01866904
THis study is intended to provide contemporary data on the burden of disease in patients 1 to 3 years post-MI, including a description of patient characteristics, current treatment patterns, rate of major CV events, and healthcare resource utilization in a 'real world' patient population at high atherothrombotic risk.
NCT00411892
This trial is conducted in the United States of America (USA). This trial will compare the changes in HbA1c after 26 weeks of inhaled insulin and pioglitazone combination therapy versus pioglitazone treatment alone.
NCT02242643

NCT00711802
This is a multi-center, evaluator-blinded, randomized, comparative study designed to assess the safety, efficacy, and pharmacokinetics (PK) of daptomycin in pediatric subjects ages 1 to 17 years, inclusive, with complicated skin and skin structure infections (cSSSI) caused by Gram-positive pathogens.
NCT00619983
The purpose of the study is to determine whether the combination of the the three drugs gabapentin, duloxetine, and donepezil are effective in treating pain in people with diabetic neuropathy or patients with failed low back syndrome (chronic back pain).
NCT00621530
Chronic pain in patients following total hip replacement seems to be a significant problem. Previous research has shown that more effective pain management in the early postoperative period may decrease the incidence of the development of chronic pain states. This study will evaluate whether ketorolac (a non steroidal anti-inflammatory drug) given into the spinal fluid before surgery will reduce the area of sensitivity (or pain to light touch) following surgery. Patients will be monitored during their postoperative hospital stay and then contacted by telephone at 8 weeks and 6 months after surgery and questioned about any pain they are having at their surgical site. Patients that are still experiencing pain at 6 months will be asked to return to the medical center for the study staff to assess their pain or sensitivity at the surgical site.
NCT02967523
This project involves the collection and analysis of retrospective and prospective data on patients diagnosed with hepatocellular carcinoma (HCC) in which the Surefire Precision Infusion System was used/will used be to deliver transarterial chemoembolization with doxorubicin-eluting beads (DEB-TACE). The purpose is to compare tumor and medical response in a real-world setting as well as identify potential areas for future clinical research.
NCT01473407
The purpose of this study is to demonstrate therapeutic equivalence of IV Epoetin Hospira compared to IV Epogen (Amgen), based on maintenance of Hb levels and study drug dose requirements in patients treated for anemia associated with chronic renal failure and on hemodialysis.

NCT00741260
This is a world wide phase 1/2, open-label, study of neratinib in combination with capecitabine, conducted in 2 parts. In Part 1, 3 to 9 subjects with solid tumors will be enrolled in each dose group of the combination of neratinib and capecitabine. Each subject will participate in only 1 dose group. Additional subjects may be included at any dose level to further assess the safety and tolerability at that dose level. In Part 2, up to 60 subjects with erbB-2 positive metastatic breast cancer will receive treatment with the combination of neratinib and capecitabine at the maximum tolerated dose level, as determined in Part 1. In addition 20 subjects with prior lapatinib exposure will be enrolled in Part 2. Depending on the safety and activity profile observed during the dose escalation phase, the dose selected for Part 2 may be adjusted, if appropriate. In case one test article of the combination is discontinued due to intolerance the other test article can be administered alone. The primary objectives of Part 1 are to assess the safety and tolerability, and to define the maximum tolerated dose (MTD) of neratinib in combination with capecitabine in subjects with advanced solid tumors. The primary objective of Part 2 of this study is to confirm the MTD determined in Part 1. The secondary objective of Part 1 is to collect information on preliminary anti-tumor activity of the combination of neratinib and capecitabine. Secondary objectives for Part 2 are to collect pharmacokinetic information and to obtain additional efficacy data, such as Objective Response Rate, for subjects with erbB-2 positive breast cancer treated at the MTD of neratinib + capecitabine.
NCT00652470
The purpose of this study is to study whether infants with triventricular hydrocephalus (TVH) have a better long-term outcome at 5 years when they are treated with a new procedure, endoscopic third ventriculostomy (ETV), than infants treated with the more traditional treatment, insertion of a cerebrospinal fluid (CSF) shunt.
NCT00675987
The main purposes of this study are to find out if the study drug losartan (Cozaar) or placebo ("sugar pill") has an effect on insulin sensitivity (how your body responds to insulin) and to measure the effect of the study drug losartan or placebo on how the arteries in your arm dilate (enlarge to carry more blood). We hope to learn if taking losartan changes the amount of certain proteins in the blood that effect blood vessel function. Losartan is approved by the US FDA to treat high blood pressure. It will take approximately 4 months for you to complete this study.
