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 Fetal Atrial Flutter and Supraventricular Tachycardia (FAST) Therapy Trial is a prospective multi-center trial that examines the efficacy and safety of standard prenatal antiarrhythmic treatment. Study components of FAST include three prospective sub-studies to determine the efficacy and safety of commonly used transplacental drug regimens in suppressing fetal AF without hydrops (Randomized Clinical Trial (RCT) A), SVT without hydrops (RCT B), and SVT with hydrops (RCT C). All RCTs are open label phase III trials of standard 1st line therapy, which either is started as monotherapy (no hydrops) or as dual therapy (hydrops).
The purpose of this pilot study is to determine the effect of 3 months use of enhanced Oral Nutritional Supplement (ONS) on physical function and functional performance in malnourished elderly patients.
The human papilloma virus (HPV) is known to be an important cause of cervical and anal cancers. Studies on patients who have received a solid organ transplant (such as a liver or kidney transplant) have suggested the risk of HPV-related cancers may be higher in this population. The HPV vaccine, Gardasil®, has been approved for use in males and females by Health Canada. In studies on healthy subjects this vaccine is nearly 100% effective at preventing infections from HPV serotypes that are in the vaccine. These serotypes, representing different viral strains, are known to cause 70% of cervical cancers and 90% of genital warts. The vaccine was also shown to be very safe and well tolerated in healthy subjects. Transplant patients are at higher risk of HPV related complications and cancers. As a result transplant experts have recommended this vaccine for use in their patients; however there have been no studies looking at the response to vaccination or safety of this vaccine in solid organ transplant recipients. Our objective is to study the immune response and side effects of Gardasil® in children who have received kidney or liver transplants. We will study this by comparing immune responses to the vaccine in healthy adolescent females compared to female liver and kidney transplant recipients. We will be recruiting females ages 12-19, as the province of Ontario funds the vaccine for this group. We will evaluate the transplant subjects for side effects after they receive the vaccine. Our hypothesis is that transplant recipients will have lower immunogenicity than healthy controls.
Colorectal cancer (CRC) is one of the leading causes of cancer mortality in Canada. Rectal cancers are now known to be hypoxic which is a negative prognostic factor and predictive of metastatic spread and poor responsiveness to treatment. This has also been shown in preclinical xenograft models. Hence there is a need for identification of hypoxic rectal cancers. In this pilot study the investigators intend to non-invasively assess the tumor and nodal metastasis using an integrated Positron Emission Tomography-Magnetic Resonance Imaging scanner (PET/MRI) with 18F-Fluoroazomycin Arabinoside (18F-FAZA) a radiopharmaceutical for assessing tumor hypoxia. The hypoxic rectal tumors will show an increased uptake of 18F-FAZA on PET which will have morphological correlation on MRI. The patient will then undergo neoadjuvant chemoradiation therapy (CRT) followed by repeat 18F-FAZA PET/MRI and rectal cancer surgery with pimonidazole staining. Pimonidazole is an extrinsic marker of hypoxia that is selectively reduced and covalently bound to intracellular macromolecules in areas of hypoxia within normal and tumor tissue with current approval for use in humans for research studies. The primary goal of this pilot trial is to validate FAZA-PET as a biomarker of hypoxia by correlating its uptake in rectal tumors to pimonidazole staining in histopathology specimens. If the investigators pilot study successfully demonstrates the uptake and correlation of pimonidazole and FAZA-PET, the investigators would like to initiate a larger study examining hypoxia in rectal cancer. The investigators aims would be to image patients with locally advanced rectal cancer before CRT to ascertain whether high FAZA-PET uptake correlates with poor outcome to CRT. The ability to preoperatively predict the patient sub-population that will respond best to CRT, will help to identify the "complete pathological" responders and avoid unnecessary surgery. Furthermore, the FAZA-PET high subset of patients may benefit from other treatment strategies including clinical trials of anti-hypoxic agents.
The purpose of the study is to determine whether in patients with early type 2 diabetes,a short-term intensive metabolic intervention comprising of sitagliptin, metformin, basal insulin glargine and lifestyle approaches will be superior to standard diabetes therapy in achieving sustained diabetes remission.
Study Design: Phase 4, pilot, single center, observational study. MEP's will be obtained twice, two weeks apart at baseline and every 6 months for 36 months (total of 14 sessions of MEP's) MEP's will include: 1. Onset latencies and CMCT to bilateral abductor pollicis brevis and tibialis anterior muscles 2. MEP amplitudes and the ratio of the central to peripherally obtained motor amplitudes (MEP-M ratio) to bilateral abductor pollicis brevis and tibialis anterior muscles Clinical measures (EDSS, MEP's, T25FWT, 6MWT, 9HPT) will be obtained at baseline and every 6 months for 36 months. Study location: Single center in Canada Study Objectives: Primary: To evaluate the reliability of MEP's in Alemtuzumab treated MS patients over a 36 month period. Secondary: To determine the degree of correlation between MEP's and presently used clinical measures of efficacy (EDSS, 6MWT, T25FWT, 9HPT) and to determine if MEP's can predict who will require a third cycle of Alemtuzumab.
Dairy products consumption is widely recommended in a healthy diet not only for bone growth and maintenance, but also as a protein, calcium and magnesium sources for an adequate diet. However, dairy products are a major dietary source of saturated fat that is associated with increased risk of coronary heart disease. ln this context, dietary guidelines still advocate a restriction in dietary saturated fat for optimal heart health. Nevertheless, the association between saturated fat and the risk of heart disease remains highly controversial within the scientific community. There is also emerging evidence that the impact of dietary saturated fat will be significantly influenced by the food matrix through which it is provided. Recent studies indicate that cheese could have a major influence on intestinal fat absorption and the magnitude of the after meal release of fat in blood circulation. This is of interest because substantial evidence exists indicating that elevated levels of the after meal fat levels are associated with increased cardiovascular risk. Therefore, the improvement of the after meal fat levels produced by cheese consumption could well be part of novel therapeutic approaches contributing to improve cardiovascular risk. The general objective of the proposed research is to investigate how cheese consumption affects the after meal release of fat in blood circulation in healthy subjects. Our hypothesis is that, compared to butter, cheese consumption will have a beneficial impact on the after meal fat levels in healthy subjects. Favourable results from the proposed study will provide novel and much warranted evidence on the importance of considering changes in the after meal fat levels, not only bad cholesterol, as part of the on-going saturated fat-heart disease debate and that cheese should indeed be part of a healthy diet.
The primary objectives of Parts A and B of this study are to evaluate the safety, tolerability, and pharmacokinetics (PK) of ascending doses of tofersen in adults with ALS and a documented superoxide dismutase 1 (SOD1) mutation. The primary objective of Part C of this study is to evaluate the clinical efficacy of tofersen administered to adults with ALS and a confirmed SOD1 mutation. The secondary objective of Parts A and B of this study is to evaluate the effects of tofersen on levels of total SOD1 protein in the cerebrospinal fluid (CSF). The secondary objectives of Part C are to evaluate the safety, tolerability, pharmacodynamic (PD), and biomarker effects of tofersen.
The Macular Edema Ranibizumab v. Intravitreal anti-inflammatory Therapy (MERIT) Trial will compare the relative efficacy and safety of intravitreal methotrexate, intravitreal ranibizumab, and the intravitreal dexamethasone implant for the treatment of uveitic macular edema persisting or reoccurring after an intravitreal corticosteroid injection. MERIT is a parallel design (1:1:1), randomized comparative trial with an anniversary close-out after 6 months of follow-up. The primary outcome is percent change in central subfield thickness from the baseline OCT measurement to the 12 week visit.
