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.
Airway hyperresponsiveness is a characteristic feature of the asthma. It is known that there is an association between airway hyperresponsiveness and eosinophilic airway inflammation. However, even though inflammation can be reduced with appropriate asthma therapy, it is typical that airway hyperresponsiveness improves only modestly with treatment. The determinants of airway hyperresponsiveness are unclear. It is also not clear as to the site of airway narrowing in asthma. It is hypothesized that airways beyond the 4th order have the greatest resistance. We hope to determine the relationships between the airway inflammation, remodeling of the airway and airway hyperresponsiveness. Through local instillation of methacholine at bronchoscopy we will be able to study proximal and distal airways and the extent to which they constrict in vivo
This study is examining the effects of short daily hemodialysis on platelet function, fluid volume control, arterial stiffness and patient quality of life, as compared to conventional hemodialysis.
The primary purpose is to investigate the effect of Botox on the treatment of congenital muscular torticollis (CMT). The investigators' hypothesis is that a Botox injection will be an effective treatment when used in conjunction with current treatment procedures.
The safety and tolerability of tyrosine adsorbed ragweed pollen allergoid with monophosphoryl lipid A (MPL) was planned to be evaluated. For this purpose, a total of 4 injections of either increasing doses of the study drug or placebo (tyrosine) was planned to be administered in 7-day intervals to healthy volunteers.
This study will compare the effect of A4I antagonist and placebo on MRI lesions,on clinical endpoints, and safety in patients with relapsing Multiple Sclerosis (MS). Eligible patients will be randomized to receive placebo or A4I antagonist, 20mg, 80mg or 300mg, po bid. Patients will undergo MRI brain scans and MS clinical evaluations at intervals throughout the study. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: This phase II trial is studying how well alemtuzumab works in treating patients with Waldenstrom's macroglobulinemia.
The purpose of this research study is to obtain experience in the use of fondaparinux (Arixtra) as compared to heparin when administered to patients who undergo percutaneous coronary intervention (PCI). PCI is a mechanical procedure used to widen the narrowing in a coronary artery in patients with symptomatic coronary artery disease. Fondaparinux and heparin are drugs that inhibit blood clotting.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether cisplatin is more effective when combined with paclitaxel or gemcitabine in treating cervical cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of cisplatin combined with paclitaxel to that of cisplatin combined with gemcitabine in treating women who have recurrent, persistent, or metastatic cervical cancer.
RATIONALE: Drugs used in chemotherapy use 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. Drugs such as efaproxiral may make the tumor cells more sensitive to radiation therapy. It is not yet known if chemotherapy combined with radiation therapy is more effective with or without efaproxiral in treating non-small cell lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy combined with radiation therapy with or without efaproxiral in treating patients who have stage III non-small cell lung cancer.
RATIONALE: Drugs used in chemotherapy use 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 chemotherapy, radiation therapy, and surgery may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, radiation therapy, and surgery in treating patients who have primary or recurrent sarcoma.
