PROJECT OVERVIEW This research is a collaboration between the Centers for Disease Control and Prevention (CDC), the Health Resources and Services Administration (HRSA), and six university-affiliated HIV clinics in the United States. Study title: Intervention Trials to Retain HIV Patients in Medical Care Study sites: The study will be performed at six HIV clinics affiliated with academic medical centers. Objectives: Using HIV patients' clinical data (without personal identifiers) routinely archived in electronic databases at the six participating clinics do the following: • To examine the extent to which a client-centered intervention delivered by trained interventionists (Phase 2 trial of the project) improves patient attendance for HIV primary care over and above the effect of the clinic-wide intervention. Phase 2 is a three-arm randomized controlled trial conducted at each of the participating six clinics. 300 patients will be enrolled in the Phase 2 trial at each clinic. One hundred will be new patients and 200 will be patients with inconsistent attendance for HIV primary care at the clinic in the prior 12 months. Patients will be randomized to: (1) an enhanced contact plus behavioral skills arm or (2) an enhanced contact-only arm in which patients will receive a longer or a shorter client-centered intervention from two trained interventionists, or (3) the standard of care arm in which patients will receive the clinic-wide intervention and routine HIV clinical care only.
NCT01853254
This open-label, non-randomized, single arm study will provide treatment or re-treatment with Pegasys (peginterferon alfa-2a) as monotherapy or in combination with Copegus (ribavirin) to patients with chronic hepatitis C infection. Patients who have received prior Pegasys monotherapy or combination therapy or who were considered eligible for treatment with Pegasys in previous donor protocols will be eligible to participate in this study. Treatment will be on investigator's decision according to the approved label for up to 48 weeks, with a 24-week safety follow-up.
NCT00264810
The RNS® System Pivotal study is designed to assess safety and demonstrate that the RNS® System is effective as an adjunctive (add-on) therapy in reducing the frequency of seizures in individuals 18 years of age or older with partial onset seizures from no more than two foci (two areas of the brain) that are refractory (drug-resistant or hard-to-treat) to two or more antiepileptic medications. Patients continue to receive their epilepsy medications while participating in the study.
NCT00277524
The purpose of the OMNI study is to characterize therapy and diagnostic utilization in study participants implanted with study devices and to describe Implantable Cardioverter Defibrillator(ICD)therapy utilization for life threatening arrhythmias in primary and secondary prevention study participants. This study will assess therapies in Medtronic pacemaker, defibrillator, and cardiac resynchronization therapy devices. The first therapy is for reducing unnecessary pacing in pacemaker patients. The second therapy provides pacing therapy in an attempt to stop fast or life threatening ventricular arrhythmias in lieu of delivering a defibrillation shock. The third therapy is a diagnostic measurement of a patient's fluid status and provides the physician information on the patient's heart failure status. The study will also assess the time to a patient's first defibrillation shock and will verify that the shock was for a fast or life threatening ventricular rhythm.
NCT00002812
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia.
NCT00684918
This protocol will evaluate the efficacy of obatoclax in older patients with previously untreated AML.
NCT01205334
Patients have a type of brain cancer called glioblastoma multiforme. Because most GBMs come back after standard therapy, patients are being asked to volunteer to take part in a research study using special immune cells. They may have already thought about being in this study. Some patients with GBM show evidence of infection with a virus called Cytomegalovirus before the time of their diagnosis. CMV is found in the cancer cells of some patients with GBM, suggesting that it may play a role in causing the disease. The cancer cells infected by CMV are able to hide from the body's immune system and escape destruction. We want to see if special white blood cells, called T cells, that have been trained to recognize and kill special parts of CMV infected cells can survive in the blood and affect the tumor. We have used this sort of therapy to treat different types of cancer that are positive for other viruses and have had variable results. Some patients have had responses others did not. It is not possible for us to predict if this treatment will work for GBM. The purpose of this study is to find the largest safe dose of CMV-T cells, to learn what the side effects are, and to see whether this therapy might help patients with GBM.
NCT00003203
RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining carboplatin and vincristine with radiation therapy followed by adjuvant chemotherapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed adjuvant chemotherapy in treating young patients who have newly diagnosed high-risk CNS embryonal tumors.
NCT00005977
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have non-Hodgkin's lymphoma or acute lymphocytic leukemia.
NCT00043927
This study will gather and compare data about the effectiveness and safety of two different treatments for extensive Small Cell Lung Cancer (SCLC) in patients who have not received previous chemotherapy. One treatment will use an investigational drug in combination with an FDA approved chemotherapy. The other treatment will use a combination of two FDA approved chemotherapy drugs.

The purpose of this research study is to determine if Metanx improves sensory neuropathy in persons with Type 2 diabetes. Metanx is a medical food available with a prescription from a physician. It consists of L-methylfolate, Pyridoxal 5'-phosphate, and Methylcobalamin, which are the active forms of folate, vitamin B6, and vitamin B12, respectively. Subjects will be randomly assigned to receive either Metanx or placebo for 6 months.
NCT01932866
The purpose of this randomized, controlled study is to evaluate whether the knowledge of a personalized diabetes risk score affects adherence to a 12-week diet and exercise lifestyle change program in prediabetic patients. The intervention group will receive diabetes risk score results at the beginning of the twelve weeks, and the control group will not receive these results. Both groups will review their baseline and 12-week diabetes risk score results at the conclusion of the program and will be followed for an additional twelve weeks. Attendance rates and changes in weight, BMI, abdominal circumference, blood pressure, HgA1c, fasting blood glucose, cholesterol, and diabetes risk score will be compared between the groups.
NCT01161563

NCT00862082
The current understanding of PR104 justifies the evaluation of PR104 with sorafenib in patients with hepatocellular carcinoma. These include: * Hypoxia. Hepatocellular Carcinoma (HCC) is likely to demonstrate a level of hypoxia sufficient to activate PR104 to its active metabolites PR104H and PR104M. In addition, in preclinical models, sorafenib has been demonstrated to increase the degree of hypoxia in tumors following treatment. * Non-overlapping toxicity. PR104 and sorafenib do not share major toxicities. It is anticipated that both drugs can be administered at their full single agent dose when used in combination. * Aldo-keto reductase 1C3 (AKR1C3). HCC has been shown to express high levels of AKR1C3 which should lead to selective activation of PR104 within both hypoxic and oxic HCC cells. * Preclinical data. The use of sorafenib and PR104 alone and in combination in a hepatocellular carcinoma model demonstrates activity of PR104 as a single agent and increased activity when PR104 and sorafenib are used in combination. The current study will provide an estimate of the activity of PR104 in subjects with HCC. This information will prove valuable in defining the future clinical development of PR104, and in determining if PR104 has sufficient activity in HCC to warrant a larger phase III registration study in this indication. Primary objectives * Phase I: Determine the maximum tolerated dose (MTD) of PR104 when used in combination with standard dose sorafenib * Phase II: Estimate the response rate (RR) of PR104/sorafenib \[Note: Phase II was never initiated\] Secondary objectives * Evaluate survival * Evaluate Progression Free Survival (PFS) * Evaluate time to progression (TTP) * Evaluate safety * Evaluate the pharmacokinetics (PK) of sorafenib, PR104 and PR104 metabolites * Collect diagnostic biopsy samples for the determination of aldo-keto reductase 1C3 * Collect plasma samples for assessment of potential biomarkers of tumor hypoxia
