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.
The purpose of this study is to determine the effectiveness of adjunctive treatment of pregabalin with [S,S]-Reboxetine against pregabalin monotherapy in patients with PHN
The clinical trial is designed to evaluate the safety of inhaled Technosphere/Insulin compared with non-inhaled anti-diabetic therapies in subjects with type 1 or type 2 diabetes mellitus and concurrent asthma.
The purpose of this study is to see whether care gap(s) exist in the management of obesity and its related conditions in obese patients seen by primary care physicians and specialists. The study will also look at whether there is a compliance and adherence gap that exists in patients prescribed medication for obesity management.
The purpose of this study is to determine the benefits of treating subjects with neovascular age-related macular degeneration (AMD) at an earlier stage of choroidal neovascularization (CNV) as compared to those with established CNV. Additionally, the study would like to determine the efficacy of Macugen in preserving visual function in those subjects having CNV secondary to neovascular AMD.
The objective of this study is to evaluate the safety and efficacy of aprotinin as compared to placebo, in reducing the need for blood transfusion in adult subjects undergoing elective spinal fusion surgery involving 3 to 7 vertebral levels with instrumentation
During their hospitalization, burn patients frequently require dressing changes that may be painful. Deep analgesia and sedation are used but carry the risk of remnant somnolence and other effects of anesthesia such as dizziness and nausea/vomiting. All these side effects may delay refeeding after the procedure, ambulation and physical therapy. Drugs from the opioid class are used to relieve pain during these procedures. Morphine with its slow onset and remnant sedation is difficult to use in these patients. Pro-emetic properties and histamine liberating effects also make this drug non optimal for iterative procedures. Fentanyl, a synthetic opioid with shorter onset and lower incidence of nausea and vomiting, is the standard drug used in dressing changes in burn patients. It is metabolized by hepatic glucoconjugation. Remifentanil, a well known novel opioid, that has a unique metabolism independent from renal or hepatic functions, is metabolized by a non specific esterase. It has a very short half-life (3.5 minutes) and should therefore be administered as a continuous infusion. The investigators hypothesized that the use of remifentanil for daily burn dressing changes is associated with less pain during procedures and faster recovery. Studied patients will be the ones requiring iterative dressing change procedures under sedation. The primary endpoint will be the maximal pain during the procedure. Secondary endpoints will be: average pain during and after the procedure; subjective sensation of comfort; total amount of opioids received; times to feeding after the procedure and ambulation after the procedure; comfort of the procedure according to the nurses; mobilisation according to the physical therapist; and safety of the analgesia technique. The study will be conducted according to the recommendations of the American Society of Anesthesiologists (ASA) that have been endorsed by the Canadian Anaesthetists' Society (CAS). All patients who consent will fast for at least 6 hours before the procedure. The two following regimens will be compared: a bolus infusion of fentanyl, starting with 1 µg/kg, followed by 0.5 µg/kg as needed every 5 to 10 minutes versus continuous infusion of remifentanil adapted to ensure analgesia. The initial dose of remifentanil will be 0.1 µg/kg/min to be adjusted between 0.05 µg/kg/min and 2 µg/kg/min. To allow blinding during the study, patients will receive a double-blinded protocol with sham (normal saline) in one arm. In other words: for each procedure, the patient will always receive boluses, either of fentanyl or saline, and a perfusion, either of remifentanil or saline. According to power calculations, 30 patients will be necessary to achieve the primary end-points. The investigators plan to enroll 40 patients in the study to allow for some drop outs and to increase their statistical power.
To conduct a pilot study to evaluate the feasibility of a large randomized controlled trial (RCT) of metformin in patients with heart failure and type 2 diabetes and to generate initial morbidity and mortality estimates in this patient population. The primary hypothesis is that subjects with heart failure and type 2 diabetes who receive metformin will have a significant reduction in the combined endpoint of all-cause mortality and all-cause hospitalization as compared to subjects who receive placebo therapy.
Patients with osteoporotic vertebral body compression fractures will be randomly assigned to treatment with balloon kyphoplasty or vertebroplasty. Over 2 years of follow-up, back pain, back function, quality of life, adverse events, subsequent fractures and cumulative healthcare costs will be compared.
Positron Emission Tomography (PET) is a Nuclear Medicine procedure that uses positron emitting radiolabeled tracer molecules to visualize biological activity. The presence of hypoxia (low oxygen) is associated with poor prognosis in a variety of tumour types and treatment strategies targeting hypoxic cells have been developed. The PET tracer [18]F-FAZA can identify hypoxic areas, and changes in uptake during treatment may predict tumour response.
This trial is conducted in the United States of America (USA) and Canada. The aim of this research is to compare the efficacy (reduction in HbA1c and blood glucose) and pulmonary safety (pulmonary function, chest x-rays) of mealtime inhaled insulin with subcutaneous insulin aspart both in combination with insulin determir in Type 1 Diabetes.
