NCT00465088
To demonstrate that niacin ER and simvastatin (NS) tablets, when compared to atorvastatin (Lipitor®; Pfizer, Inc.), has superior high-density lipoprotein cholesterol (HDL-C) elevating effects at Week 12 in subjects with type II hyperlipidemia or mixed dyslipidemia who are currently off lipid-modifying therapy. This was a prospective, randomized, open-label, blinded endpoint (PROBE) study.

NCT00164463
This substudy of TBTC Studies 27 and 28 compares 1) the pharmacokinetics of moxifloxacin alone versus moxifloxacin administered with rifampin in healthy volunteers and 2) the pharmacokinetics of moxifloxacin among patients with tuberculosis being treated with multidrug therapy (isoniazid or ethambutol, rifampin, and pyrazinamide) to those of healthy volunteers receiving moxifloxacin plus rifampin. It also evaluates the association between polymorphisms of MDR1 genotype (P-glycoprotein) and rifampin pharmacokinetic parameters, the effect of polymorphisms of MDR1 genotype and/or rifampin pharmacokinetics on isoniazid pharmacokinetic parameters adjusted for N-acetyltransferase genotype (NAT2), and determines by multivariate regression analyses the associations between moxifloxacin or rifampin pharmacokinetic parameters and markers of tuberculosis disease severity including the covariates of two-month culture positivity, cavitary lung disease, Body Mass Index, weight, duration of study treatment prior to PK, co-morbidities and C-reactive protein. Healthy volunteers and TB patients receive frequent scheduled blood draws during a 24 hour period after ingesting a dose of TB drugs.

NCT00419705
The purpose of this pivotal study is to demonstrate safety and effectiveness of the NeuroThera® Laser System (referred to hereafter as NTS) in the treatment of Subjects diagnosed with acute ischemic stroke. The initiation of NTS treatment must be feasible for each Subject within 24 hours of stroke onset.
NCT00235391
This is an open-label, non-randomized, multi-center trial designed to provide expanded access of deferasirox to patients with congenital disorders of red blood cells and chronic iron overload from blood transfusions who cannot adequately be treated with locally approved iron chelators.
NCT00024557
IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13 receptor-positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells. Patients will receive IL13-PE38QQR via a catheter placed directly into the brain tumor. Tumor recurrence will be confirmed by biopsy. The next day, patients will start a continuous 48-hour infusion of IL13-PE38QQR into the tumor. The dose (concentration) will be increased in the pre-resection infusion until the endpoint is reached (histologic evidence of tumor cytotoxicity or a maximum tolerated dose). Tumor resection will be planned for one week after biopsy, plus or minus 1 day. A histologically-effective concentration (HEC) will be determined using pathologic observations. At the end of resection, three catheters will be placed in brain tissue next to the resection site and assessed within 24 hours using MRI. On the second day after surgery, IL13-PE38QQR infusion will begin and will continue for 4 days. The lowest pre-resection IL13-PE38QQR concentration will be used as the starting dose for post-resection infusions. After an HEC or maximum tolerated dose (MTD) is determined, the pre-resection infusion will no longer be administered. Subsequent patients will have tumor resection and placement of three peri-tumoral catheters at study entry. IL13-PE38QQR will be infused starting on the second day after surgery and continuing for 4 days. Escalation of the post-resection IL13-PE38QQR concentration will be continued until the previously-defined HEC or MTD is reached, after which duration of the post-resection infusion will be increased in one day increments for up to 6 days. If a post-resection MTD is obtained, there will be no increase in duration of infusion. In the final stage of the study, catheters will be placed 2 days after tumor resection, and a 4-day IL13-PE38QQR infusion will begin the day after catheter placement. Patients will be observed clinically and radiographically for toxicity and duration of tumor control.

NCT00100386
Primary Outcome Measures:Incidence density of colonization with MRSA or VRE (number of new colonization events per 1000 patient days at risk) during the intervention phase. Secondary Outcome Measures:The effect of the 2 strategies on the incidence density of colonization with MRSA and VRE individually will be determined and compared descriptively. The effect of the strategies on the cumulative incidence of bacteremia caused by MRSA and VRE will be determined to assess the clinical relevance of the strategy in preventing infection. The trial will evaluate the frequency of hand hygiene and the use of gloves and gowns by healthcare workers to substantiate whether the effect of the intensive control strategy is mediated, as expected, by an increase in the use of gloves and gowns due to an increase in the number of patients cared for using Contact Precautions.

NCT00644293
To determine if a single 2.0-g dose of azithromycin SR is at least as effective as a 3-day course of azithromycin (500 mg once daily for 3 days) when used to treat adolescents and adults with strep throat, and to assess efficacy and safety for both treatment regimens.
NCT00761332

NCT00131560
This study uses autologous (one's own) CD4 T cells modified with a viral vector expressing a genetic antisense targeting HIV, this vector is called VRX496. Study treatment is by intravenous infusion of vector modified cells and infusions will be provided every other week for a total of 4 or 8 doses. These modified cells, once infused, may provide immune support and are not destroyed by HIV, and thus may delay or reverse HIV disease progression. The study will enroll up to 40 male and female HIV-positive subjects in up to 8 centers. Subjects will be 18 years of age and over who have failed or are intolerant to at least one triple combination of antiretroviral drugs. Subjects must have a viral load between 5,000 and 200,000 copies/ml and a CD4+ count of ≥150, be in good health and have no evidence of active opportunistic infection, heart disease, or bleeding disorders. Subjects must not be on corticosteroids, immunomodulating agents or hydroxyurea. Subjects must not have received an AIDS vaccine or any investigational gene therapy product at any time. Females must not be pregnant or breastfeeding.
