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.

In addition we will study the safety and tolerability of these compounds over the 48 week study period in patients naive to anti-HIV therapy.
NCT01206621
For the patient with acute dyspnea in the ED, early differentiation between CHF and non-CHF causes is essential for proper management. The capacity to triage patients quickly and accurately has a beneficial impact upon outcome, disposition, stratification and length of stay in the ED and required length of hospital admission. The ability to assess pulmonary status rapidly by quantitative regional vibration technology offers significant potential advantage for earlier diagnosis. The VRI technique may provide a quick and accurate method of differentiating between dyspnea due to HF and dyspnea due to pulmonary causes; thereby improving management and outcomes.

NCT00616213
RATIONALE: Drugs used in chemotherapy, such as PR-104, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Colony-stimulating factors, such as G-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving PR-104 together with G-CSF may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of PR-104 when given together with G-CSF in treating patients with solid tumors.
NCT00644449
This study was performed to confirm that a single 2.0-g dose of azithromycin SR is at least as effective as 7 days of levofloxacin 500 mg/day in adults with acute exacerbation of chronic bronchitis Secondary objectives: To assess safety and the bacteriologic efficacy of both treatment regimens
NCT00311701
This retrospective study conducted in Canada and the US involves a chart review to assess the safety of oseltamivir (Tamiflu®) compared to alternate antiviral therapy, amantidine or rimantidine, administered to children less than 12 months of age with diagnosed or suspected influenza. The objectives are to describe the frequency of neurological and all other adverse events possibly related to administration of these antivirals in these infants. Investigators will also compare frequency of adverse events at various doses of oseltamivir in these children. Critical endpoints to be collected include frequency and severity of adverse events, particularly those relating to central nervous system complications. A sub-investigator will travel to each of the participating sites to collect data related to each infant's health prior to becoming ill, health status at time of influenza diagnosis, dosing regimen, reported neurological events post-dosing, and all reported adverse events post-dosing.

NCT00478075
RATIONALE: Radioactive drugs, such as samarium Sm 153 lexidronam pentasodium, may carry radiation directly to cancer cells and not harm normal cells. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Bortezomib may also make cancer cells more sensitive to radiation therapy. Giving samarium Sm 153 lexidronam pentasodium together with bortezomib may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of bortezomib when given together with samarium Sm 153 lexidronam pentasodium and to see how well they work in treating patients with relapsed or refractory multiple myeloma.
