NCT00359424
The purpose of this study is to compare two different treatment approaches to recanalization started within 3 hours of symptom onset-combined intravenous (IV) and endovascular therapy and standard intravenous (IV) rt-PA alone.
NCT01322945
The purpose of this study is to evaluate patient nasal outcome following endo-nasal surgery. This type of surgery is conducted for pituitary and skull base tumors. There is no published data on trauma to the nose during surgery and how it impacts nasal functioning. The investigators propose to develop a survey and administer it to patients before and after surgery to learn about their perception of nasal functioning.

NCT00005959
RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one chemotherapy drug with rituximab may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of rituximab plus combination chemotherapy in treating patients who have intermediate-grade or high-grade non-Hodgkin's lymphoma.

NCT00405275
Rheumatoid arthritis (RA) is a chronic inflammatory disease of the joints leading to joint destruction, with significant long-term morbidity and mortality. Early treatment of RA patients with disease-modifying antirheumatic drugs (DMARDs) significantly decreases these complications. Methotrexate (MTX) is an excellent, economical first-line DMARD used to treat a majority of RA patients. While most patients respond well to MTX, many continue to have active disease. Therefore, understanding how to best treat RA patients with active disease despite MTX therapy is critically important. Although a number of therapies with significantly different economic implications have been shown to be effective when added to MTX, no trial has directly compared active therapies. This study will compare therapeutic strategies using two regimens with proven efficacy when added to MTX therapy; a) hydroxychloroquine and sulfasalazine (cost \~ $1000 per year); b) the tumor necrosis factor inhibitor, etanercept (cost \~ $12,000 per year). We propose a bi-national multi-center randomized, double-blind equivalency trial comparing (A) the strategy of initially adding hydroxychloroquine and sulfasalazine to MTX in patients with active disease despite MTX, with a switch at 24 weeks to etanercept in nonresponders to (B) a strategy of adding etanercept to MTX, with a switch to hydroxychloroquine and sulfasalazine in nonresponders at 24 weeks. If we find that the strategy of first adding hydroxychloroquine and sulfasalazine to MTX identifies a subset of responsive patients and that there is no harm to nonresponders because of early rescue with etanercept, then this less expensive option should become the standard treatment for MTX resistant patients. Four hundred and fifty RA patients with active disease despite treatment with MTX as indicated by a Disease Activity Score with 28 joints (DAS28) of \>4.4 units will be randomized. A DAS improvement of \<1.2 (validated as clinically significant) at 24 weeks will be used to identify early nonresponder who will switch therapy. Subjects with a DAS28 improvement of \> 1.2 at 24 weeks will remain on their initial therapy. The primary endpoint is the change of DAS 28 scores from baseline to 48 weeks. The secondary endpoint is comparison of radiographic progression of disease at 48 weeks, as measured by the change in Sharp score. Economic and functional outcomes will be assessed and a serum and DNA bank will be established to evaluate potential biomarkers predictive of treatment response/toxicity and disease progression. This trial will recruit 450 subjects over 40 months. At the end of the 48 week blinded active therapy portion of the trial, the blind will be broken and data will be collected in an open fashion until all 450 patients have completed the 48 week portion of the trial.
NCT00933543

NCT00005958
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy with gemcitabine and docetaxel plus filgrastim in treating patients who have locally recurrent or advanced urothelium cancer.
NCT00262067
This is a Phase III, multicenter, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of bevacizumab in combination with chemotherapy compared with chemotherapy alone in subjects with previously untreated metastatic breast cancer.
NCT01797250
To determine accuracy specifications of the pulse oximeter in the NEO/PEDS subject population
NCT00005960
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have prostate cancer that has not responded to hormone therapy.
NCT00003942
RATIONALE: Inserting the gene for RevM10 into a person's peripheral stem cells may improve the body's ability to fight cancer or make the cancer more sensitive to chemotherapy. PURPOSE: Phase I/II trial to study the effectiveness of RevM10-treated stem cells plus chemotherapy and peripheral stem cell transplantation in treating patients who have HIV-related non-Hodgkin's lymphoma.
NCT00033423
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody in treating patients who have relapsed or refractory non-Hodgkin's lymphoma.
NCT00597038
The purpose of this study is to: Phase I Objectives: * Find the most tolerated dose to use for Phase II * Collect information on how the body responds to this combination of study drug Phase II Objectives: * To determine the overall response of participants using this combination of study drug The expression of proto-oncogene tyrosine-protein kinase (Src), a substance present in a significant proportion of melanomas plays a role in the growth, multiplying, and dividing of cancer cells. Melanoma cells appear to be sensitive to these agents that block the action of Src in concentrations that can be achieved in patients. We suggest that Src inhibitors (such as Dasatinib) may be a good choice for treatment of melanoma in combination with Dacarbazine (a chemotherapy drug that can cause the shrinkage of melanomas). We wish to to evaluate the Src inhibitor Dasatinib in combination with the chemotherapy drug Dacarbazine. The novel oral Src inhibitor Dasatinib may be able to increase the effectiveness of chemotherapy for melanoma compared to chemotherapy alone. Dacarbazine is a standard treatment for melanoma currently. The effectiveness of this chemotherapy drug may be increased by combination with Dasatinib. Dacarbazine has been approved by the US Food and Drug Administration (FDA) for treating melanoma; Dasatinib has been approved by the FDA to treat leukemia, but it has not been approved alone or in combination with Dacarbazine to treat melanoma.

NCT01871948
Cancer patients often experience problems in their care, many of which are caused by communication breakdowns. Some communication breakdowns lead to adverse events and even harmful errors. Deficiencies in provider-patient communication can compound patients' distress, lower the quality of care, and disrupt patient-provider relationships. There is little research on patients' and providers' experiences of the communication breakdowns that precipitate adverse events and errors, or on effective responses to these events. Because of this, cancer providers are unsure how to communicate with patients in these difficult situations. The goal of the proposed study is to improve patient-centered communication around adverse events and errors in cancer care. Our specific aims are: 1) To describe patients' experiences with communication around adverse events and errors in cancer care, 2) To describe providers' experiences and practices with communication around adverse events and errors in cancer care, 3) To develop practical recommendations, provider training materials and patient educational materials for improving communication around adverse events and errors in cancer care, 4) To disseminate the recommendations and materials through three health plans, and 5) To conduct a preliminary evaluation of the perceived usefulness and impact of the materials. The investigators will first conduct interviews with breast and colorectal cancer patients who have experienced adverse events or errors at 3 Cancer Research Network (CRN) health plans (Atlanta, Georgia; Seattle, Washington and Worcester, Massachusetts). The interviews will focus on instances where patients believe that better communication might have prevented an adverse event or error, or mitigated the event's impact. Next the investigators will conduct focus groups to understand providers' attitudes and experiences with these communication dilemmas, and use simulations to describe providers' communication practices. Finally, the investigators will interview health plan leaders to identify the systems factors that influence communication with patients around adverse events and errors. These perspectives will be synthesized to create patient and provider educational material for improving communication. Three advisory panels: a Patient Advisory Panel, a Health Plan Advisory Panel and a Dissemination Advisory Panel (including all 14 CRN health plans) will help create and disseminate these educational interventions. Dissemination will occur at the three core clinical sites. The investigators use patient and provider surveys to evaluate the educational materials' impact. This evaluation will provide the evidence-base to refine the study products before widespread dissemination throughout the CRN and beyond. The project will have the advantage of the CRN infrastructure, the CRN Clinical Communication Research Center, and is led by nationally recognized communication researchers.
