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 EchoCRT trial evaluates the effects of Cardiac Resynchronization Therapy (CRT) on mortality and morbidity of subjects with heart failure due to left ventricular systolic dysfunction, already receiving optimized HF medication, with a narrow QRS width (< 130 ms) and echocardiographic evidence of ventricular dyssynchrony.
This study will determine if administration of an suspension of calfactant, a lung surfactant, intratracheally in patients with Direct Acute Respiratory Distress Syndrome within 48 hours of requiring mechanical ventilation can decrease the mortality in patients with lethal disease and shorten the course of respiratory failure in patients with sub-lethal disease.
Consecutive patients with a first diagnosis of breast cancer will be identified at the Tom Baker Cancer Centre (TBCC) and included into the study, if they are going to receive chemotherapy with anthracyclines and / or Trastuzumab and do not have contra-indications for the CMR study. Besides the usual clinical care for these patients (e.g. blood samples before each cycle of chemotherapy; MUGA scans to follow cardiac size and function), the patients will undergo serial contrast-enhanced CMR studies (before, during and 9-12 months after completion of the chemotherapy); patients will be seen at an outpatient clinic in the Dept. of Cardiac Sciences / Heart Function Clinic for a clinical assessment (including ECG, additional blood test like Troponin-T, BNP, 6-minute-walk-test) and recommendations will be made to medical treatment in patients with evidence for heart failure. Time points for the CMR and clinic assessments will be co-coordinated with regularly scheduled test by the TBCC to avoid unnecessary burden for the patients. The oncologists at the TBCC will be blinded to the results of the CMR studies and to laboratory results, unless the participating cardiologists identify a clinical need for communication. Standardized CMR protocols will be employed and all interpretations will be blinded to the time course of the chemotherapy and cardiotoxic side effects. We will test the hypothesis, whether CMR can be useful in patients with potentially cardiotoxic chemotherapy to: - Identify patients at risk for the development of grade 2-4 cardiotoxic side effects as classified by the NCI guidelines (common toxicity criteria, 2001, 1-12) - Identify imaging parameters to predict early or late Cardiotoxicity - Provide additional clinical information to optimize medical treatment for heart failure
The purpose of this study is to assess the ability of eltrombopag to elevate platelet counts thereby reducing the need for platelet transfusions in chronic liver disease patients with thrombocytopenia undergoing elective invasive procedures. The clinical benefit of eltrombopag will be measured by the proportion of subjects who avoid platelet transfusions, before, during and up to 7 days after undergoing an invasive procedure. In addition, bleeding events will be monitored during this time. The number of transfusions, safety events and medical resource utilisation will be monitored during this time and for up to 30 days after undergoing an invasive procedure to help further evaluate clinical benefit.
The objective of this study is to demonstrate a reduction of intrahepatic fat as measured with Proton Magnetic Resonance Spectroscopy after 12 weeks administration of oral acarbose. The study will also examine the hypothesis of whether the chronic administration of acarbose in patients with NAFLD will influence postprandial substrate metabolism reflected in the RQ measured by indirect calorimetry.
This study will compare the safety and efficacy of sunitinib in combination with prednisone versus placebo and prednisone in patients that have metastatic castration-resistant prostate cancer that has progressed after treatment with a docetaxel-containing chemotherapy regimen. This is a second-line study.
Rosuvastatin is a drug used to lower cholesterol, which also has other cardiovascular benefits. The goal of this project is to determine if rosuvastatin is effective at slowing the development of heart disease in people with HIV. We expect that after 2 years of treatment people treated with rosuvastatin will show significantly better results than people treated with a placebo.
The objective of this study is to test a clinical benefit of the addition of CP 751,871 to erlotinib therapy in patients with advanced NSCLC of non adenocarcinoma histology. The primary endpoint is Overall Survival (OS).
With over one million operations a year, cardiac surgery with cardiopulmonary bypass is one of the most common major surgical procedures worldwide (1). Acute kidney injury is a common and serious postoperative complication of cardiopulmonary bypass and may affect 25% to 50% of patients (2-4). Acute kidney injury carries significant costs (4) and is independently associated with increased morbidity and mortality (2,3). Even minimal increments in plasma creatinine are associated with an increase in mortality (5,6). Multiple causes of cardiopulmonary bypass-associated acute kidney injury have been proposed, including ischemia-reperfusion, generation of reactive oxygen species, hemolysis and activation of inflammatory pathways (7-10). COMT LL genotype appears to increase the risk of vasodilatory shock and AKI after cardiac surgery. To date, no simple, safe and effective intervention to prevent cardiopulmonary bypass-associated acute kidney injury in a broad patient population has been found (11-14). Urinary acidity may enhance the generation and toxicity of reactive oxygen species induced by cardiopulmonary bypass (10,15). Activation of complement during cardiac surgery (16) may also participate in kidney injury. Urinary alkalinization may protect from kidney injury induced by oxidant substances, iron-mediated free radical pathways, complement activation and tubular hemoglobin cast formation (9,17,18). Of note, increasing urinary pH - in combination with N-acetylcysteine (19,20) or without (21) - has recently been reported to attenuate acute kidney injury in patients undergoing contrast-media infusion. In a pilot double-blind, randomized controlled trial the investigators found sodium bicarbonate to be efficacious, safe, inexpensive and easy to administer. These findings now need to be confirmed or refuted by further clinical investigations in other geographic and institutional settings. Accordingly, the investigators hypothesized that urinary alkalinization might protect kidney function in patients at increased risk of acute kidney injury undergoing cardiopulmonary bypass needs to be confirmed in an international multicenter, double-blind, randomized controlled trial of intravenous sodium bicarbonate.
The purpose of this study is to compare the effectiveness of two types of operative treatment in terms of resolving symptoms, improving function and also with respect to x-ray outcomes. The hypothesis is that insertion of a spacer will provide similar symptomatic relief, but improved long term gains in key and tripod pinch strength when compared to LRTI.
