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.
Cardiac bypass surgery is an important treatment for patients with severely blocked arteries (tubes that delivery oxygen and nutrients to the heart). Hundreds of thousands of these operations are done each year to help relieve patients' chest pain and to prevent future heart attacks. The surgery is done by "bypassing" blood flow around badly clogged arteries by sewing on healthy vessels from another part of the body (usually from the leg or the chest). Aspirin (a blood thinner) is given to patients once a day after their surgery because it stops "sticky" cells in the blood (platelets) from blocking these new vessels (which may lead to a future heart attack). Research has shown that aspirin does not work as well in people after they have bypass surgery as the investigators might expect (for reasons that are not fully understood). One reason aspirin may not work as well after surgery is because the body makes many more platelets after surgery than it would under normal circumstances. All of these new platelets overwhelm the aspirin and continue to be "sticky" and ready to block off arteries. The investigators believe that giving multiple daily doses of aspirin following bypass surgery is more effective than giving aspirin once daily at blocking platelet activity.
Alirocumab (SAR236553/REGN727) is a fully human monoclonal antibody that binds PCSK9 (proprotein convertase subtilisin/kexin type 9). Primary Objective of the study: To evaluate the effect of alirocumab on low-density lipoprotein cholesterol (LDL-C) levels after 24 weeks of treatment in comparison with placebo. Secondary Objectives: - To evaluate the effect of alirocumab in comparison with placebo on LDL-C at other time points - To evaluate the effects of alirocumab on other lipid parameters - To evaluate the safety and tolerability of alirocumab
This trial is conducted in Asia, Europe and North and South America. The aim of the trial is to investigate the effect of liraglutide versus placebo when added to basal insulin analogues with or without metformin in subjects with type 2 diabetes.
The purpose of the study is to assess whether the use of I-scan during colonoscopy leads to an increased yield of adenomas in the colon among a population at increased risk for CRC. Primary Outcome: To estimate the mean number of adenomas per colonoscopy for both high definition white light colonoscopy and I-scan enhanced colonoscopy Secondary Outcomes: 1. To estimate the recruitment rate 2. Number of adenomas detected in the right colon during the second look
The aim of this study is to determine the best method of pain control that will help with rehabilitation after total knee arthroplasty (TKA). Currently, the best method for pain control after TKA appears to be continuous femoral nerve block (FNB) where a small tube is placed beside the nerve that provides sensation to a large part of the knee and local anesthetic infused after surgery causing numbness to the surgical site. A single injection method also exists and may provide similar benefits. Both methods require training and can result in side effects such as temporary weakness (while the local anesthetic is still working) that can inhibit rehabilitation. A newer method injecting local anesthetic into the joint after surgery (Local Infiltration Analgesia (LIA)) is becoming common, does not cause weakness and can be done quickly at the end of surgery. It is unknown if the pain control provided by LIA is as good as that of FNB. This study will compare the femoral nerve block, continuous femoral nerve block and LIA technique to determine which provides better pain relief after TKA.
In optimally managed HIV+ women with undetectable viral loads, who are on HAART and also receiving intrapartum IV ZDV, the risk of vertical transmission of HIV is independent of the length of time of rupture of membranes.
The overall objective of the CHANGE initiative is to change the delivery of care in primary care clinics to treat disease by reducing reliance on drugs and hospitals through the promotion of scientifically validated nutritional concepts and exercise. Specifically, the objective is to identify patients from primary care clinics with metabolic syndrome who are not morbidly obese and use diet and exercise interventions to reverse the changes, reduce reliance on pharmacotherapy and prevent progression to diabetes and cardiovascular disease.
The purpose of this study is to assess the quality of postoperative pain management in a Canadian teaching hospital following thoracic surgery. Hypothesis: Postoperative pain management following thoracotomy or thoracoscopy is still suboptimal despite the evidence that adequate pain relief improves outcome.
Radiation synovectomy by intra-articular injection of beta-emitting radionuclides is considered a reliable and easy-to-perform therapy without harmful side-effects for the treatment of inflammatory joint disease in many countries. The goal of this study is to demonstrate Yttrium-90 citrate colloid or Rhenium-186 sulfide synovectomy are appropriate therapeutic interventions in patients with persistent active synovitis of a joint (characterized by pain, tenderness, and effusion) which is resistant to systemic therapy and intra-articular corticosteroid injections. The primary objective will be to assess the safety of an intra-articular administration of Yttrium-90 citrate colloid or Rhenium-186 sulfide. The secondary objective will be to assess the efficacy on synovitis.
The purpose of this study is to evaluate whether biomarkers of inflammation, genetic thrombophilia and coagulation activation influence Post-Thrombotic Syndrome development in patients with symptomatic proximal deep venous thrombosis.
