There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Drugs used in chemotherapy, such as topotecan, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Topotecan may make tumor cells more sensitive to radiation therapy . Giving topotecan and G-CSF together with radiation therapy may be an effective treatment for brain stem glioma. PURPOSE: This phase I/II trial is studying the side effects and best dose of topotecan when given together with G-CSF and radiation therapy and to see how well they work in treating young patients with newly diagnosed brain stem glioma.
This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Combivir in HIV infected, untreated subjects.
This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Kaletra in HIV infected, untreated subjects.
This 2 arm study will compare the efficacy of intravenous Bondronat with that of zoledronic acid in patients with malignant bone disease experiencing moderate to severe pain. Patients will be randomized to receive either Bondronat (6mg iv on days 1, 2 and 3 and then every 3-4 weeks) or zoledronic acid (4mg iv on day 1 and then every 3-4 weeks). The anticipated time of study treatment is 6-12 months, and the target sample size is 100-500 individuals.
This randomized phase III trial is studying whole-brain radiation therapy and stereotactic radiosurgery with or without temozolomide or erlotinib to see how well they work compared to whole-brain radiation therapy and stereotactic radiosurgery in treating patients with brain metastases secondary to non-small cell lung cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Stereotactic radiosurgery may be able to deliver x-rays directly to the tumor and cause less damage to normal tissue. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop tumor cells from dividing so they stop growing or die. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth and by blocking blood flow to the tumor. It is not yet known whether radiation therapy and stereotactic radiosurgery are more effective with or without temozolomide or erlotinib in treating brain metastases.
The is a double-blind, placebo-controlled, randomized, and multicenter study consisting of a first treatment (FT) period followed by either an observation (OB) period and a re-treatment (RT) period or an open-label (OL) treatment period, depending on FT period response, and a 4-week safety follow-up (FU) period. The purpose of this study is to evaluate the safety and efficacy of onercept, to be administered as 150 milligram (mg) three times a week, compared to matching placebo, for the induction of remission in subjects with moderate to severe plaque psoriasis.
The main purpose of this study is to determine if XL119 is more effective than the combination of 5-fluorouracil (5FU) and leucovorin (LV) in prolonging the survival of subjects with advanced biliary tumors.
The purpose of this study is to compare the duration of survival between GVAX® immunotherapy for prostate cancer and chemotherapy treatment in patients with prostate cancer who no longer respond to hormone therapy, who have documented metastases, and who have not been treated with chemotherapy in the past.
RATIONALE: Mycophenolate mofetil added to immunosuppressive treatment regimens may be effective in treating newly diagnosed chronic graft-versus-host disease caused by stem cell transplantation. It is not yet known whether immunosuppressive treatment regimens are more effective with or without mycophenolate mofetil in treating chronic graft-versus-host disease. PURPOSE: This randomized phase III trial is studying whether the addition of mycophenolate mofetil improves the efficacy of immunosuppressive treatment regimens in patients with newly diagnosed chronic graft-versus-host disease.
The purpose of this study is to evaluate the safety and efficacy of five fixed dosage levels of FK962 or placebo for 24 weeks in subjects with mild to moderate Alzheimer's disease. Patient visits are every six weeks with limited efficacy measurements at week 6 and 18.
