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.
Hypothesis: Sealing moderate SVG lesions with paclitaxel-eluting stents reduces cardiac events (death, myocardial infarction, target vessel revascularization) over the duration of follow-up. Primary objective: To evaluate the efficacy of stenting moderate SVG lesions with paclitaxel-eluting stents on reducing the first occurrence of the composite of cardiac death, myocardial infarction or repeat revascularization related to the target SVG over the duration of follow-up (minimun of 2-year follow-up.
This is a phase I/II open-label study that is evaluating the toxicity and efficacy of nilotinib combined with mitoxantrone, etoposide, and high-dose cytarabine (NOVE-HiDAC) chemotherapy for patients with poor-risk acute myeloid leukemia (AML). There are two parts to the study. The first part (Phase I) will determine the maximum dose of nilotinib that can safely be given when combined with NOVE-HiDAC. This dose will then be used in combination with the NOVE-HiDAC regimen in the second part of the study (Phase II), which will evaluate the antileukemic activity of the treatment. The patients who achieve complete remission from the induction therapy (1 cycle) will then receive consolidation therapy combined with nilotinib (maximum of 2 cycles). The patient population for this study will have AML and will fall into a poor risk category. This means they have persistent leukemia after induction therapy, they relapse within two years of achieving complete remission with induction therapy, or they have certain poor risk features at diagnosis. The AML cells will also be positive for c-kit (a stem cell factor receptor), which is involved in cancer cell growth. Nilotinib is a drug that blocks the effects of c-kit. Using this drug in combination with chemotherapy may improve ability of the chemotherapy drugs to kill leukemia cells. This may then increase the chances of the leukemia going into complete remission.
Antidepressant medications known as selective serotonin reuptake inhibitors (SSRIs) are most commonly prescribed to treat depression and anxiety. How antidepressants work on the brain to alter mood and behaviour is not well understood. This study will use a brain scanning technique (functional magnetic resonance imaging) to examine how aging impacts brain activation during emotional tasks after the administration of intravenous (IV) citalopram (this is the only SSRI available in this form, and is well tolerated and safe in young and old adults). The investigators will further determine what role genetic differences play in this relationship. The investigators expect to see an increase in brain signal as the concentration of IV citalopram increases. However, the investigators propose that the brain signal in older adults will not be as strong as in younger adults. Furthermore, the investigators expect that participants genetically predisposed to have fewer serotonin transporters (the site of action of SSRIs) will show greater decreases in brain activation with citalopram.
To evaluate the effects of Trientine Hydrochloride in prevention of post-laser (pan-retinal photocoagulation) macular edema in the eyes for subjects with diabetic retinopathy. Trientine hydrochloride can limit secondary inflammatory damage to retinal vessels following the administration of pan-retinal photocoagulation therapy for severe non-proliferative diabetic retinopathy or retinal neovascularization due to diabetic retinopathy, resulting in less macular edema and improved visual outcomes.
The purpose of this research study is to determine if adding or increasing the dose of CellCept while lowering the dose of tacrolimus (Prograf or Advagraf) or cyclosporine (Neoral), and/or steroids can reduce the likelihood of developing coronary heart disease in the next 10 years. The investigators will calculate the change in risk of developing coronary heart disease using the Framingham score. The Framingham score is a mathematical equation that includes the following information: Age, Gender, Diabetes status, Smoking status, Lipids, Blood Pressure. The Framingham score estimates how likely it is that someone will develop coronary heart disease over the next 10 years.
This randomized, double-blind, placebo-controlled study will evaluate the safety and efficacy of RoActemra/Actemra (tocilizumab) in patients with ankylosing spondylitis (AS) who have failed treatment with non-steroidal anti-inflammatory drugs and are naïve to tumor necrsos factor (TNF) antagonist therapy. In Part 1 of the study, patients will be randomized to receive either RoActemra/Actemra 8 mg/kg intravenously (IV) or placebo every 4 weeks for 12 weeks. In Part 2, patients will be randomized to receive RoActemra at either 8 mg/kg or 4 mg/kg IV or placebo every 4 weeks for 24 weeks. The double-blind treatment period will be followed by open-label treatment with RoActemra/Actemra 8 mg/kg iv every 4 weeks until Week 208 for all patients. Anticipated time on study treatment is 208 weeks.
This randomized, double-blind, placebo-controlled study evaluated the safety and efficacy of tocilizumab (RoActemra/Actemra) in patients with ankylosing spondylitis (AS) who had an inadequate response to previous tumor necrosis factor (TNF) antagonist therapy. Patients were randomized to receive tocilizumab at a dose of either 8 mg/kg or 4 mg/kg intravenously (iv) or placebo every 4 weeks for 24 weeks. The double-blind treatment period was followed by open-label treatment with tocilizumab 8 mg/kg iv every 4 weeks until Week 104 for all patients. This study and all further clinical development of tocilizumab AS was halted after a review of 12-week data from Study NA22823, a randomized double-blind, placebo-controlled study in TNF antagonist naïve AS patients, failed to demonstrate efficacy.
The purpose of this study is to evaluate the safety and tolerability of PF-03049423 following multiple dose administration to subjects with ischemic stroke. The study will also evaluate the efficacy of PF-03049423, relative to placebo, in subjects with ischemic stroke following 90 days of therapy. The study will also explore the relationship between PF-03049423 concentration and blood pressure.
The specific aim of the proposed study is to conduct a pilot study involving 160 critically-ill lean and obese patients enrolled at 11 sites in Canada, the United States of America, Belgium and France in order to: Specific Aims - Confirm that we can achieve a clinically significant difference in calorie and protein intake between the two intervention groups. - Estimate recruitment rate i.e. number of eligible and enrolled patients per month per site. - Evaluate the safety, tolerance, and logistics around providing supplemental PN in the study population in the context of a multicenter trial, e.g. - To ensure adequate glycemic control in both groups. - To ensure that the other metabolic consequences of the feeding strategies are minimized. - To establish adequate compliance with study protocols and completion of case report forms A secondary aim of this pilot study will be: • To explore the effect of differential effects of calorie and protein delivery on muscle and mass function.
This trial is conducted in Europe and North America. The aim of this trial is to investigate if liraglutide treatment can increase the proportion of insulin-independent subjects one year after islet cell transplantation who required only one (single-donor) islet cell transplant.
