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 primary objective of this study is to further expand the body of clinical knowledge in patients undergoing Pipeline Embolization Device (Pipeline or PED) placement for intracranial aneurysms (IAs or ICAs) according to Pipeline's labeled indication.
Nimodipine (Nimotop® Bayer Pharmaceuticals Corporation), unlike other calcium channel blockers is fat soluble and therefore is able to cross the blood-brain barrier1. Gonadotropin releasing hormone (GnRH) neurons are clustered in the hypothalamus and are dependent on calcium flux to release GnRH responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. In a natural menstrual cycle a spontaneous LH surge occurs mid-cycle which triggers ovulation. The investigators hypothesized that nimodipine, by blocking calcium channels, may effectively suppress the release of GnRH and consequently the natural LH surge. In this prospective double-blinded randomized study the investigators will evaluate the efficacy of nimodipine to inhibit the natural LH surge in women undergoing controlled ovarian stimulation (COS) and intrauterine insemination (IUI). Nimodipine, if successful, may represent an inexpensive oral medication as an alternative to the currently used GnRH agonists or GnRH antagonists in assisted reproductive technologies like IVF.
This study aims to assess the effect of Avastin on brain vascularity and blood-brain permeability using dynamic contrast ct scans (DECT) and MRI imaging. Previous publications have documented the method by which DECT can determine alterations in vascular volume and tissue permeability within tumors and normal brain tissue. Functional maps of cerebral blood flow cerebral blood volume and permeability-surface area can be generated from the DECT studies to assess tumor perfusion. MRI spectroscopy analyzes brain chemistry to detect tumour versus edema versus normal brain. Thirty patients will receive MRI spectroscopy and DECT imaging at the time of presumed recurrence and 3 months later. 15 patients who do not receive Avastin and 15 patients who do receive Avastin as standard treatment for recurrence will be studied with DECT and MRI spectroscopy at baseline and then again in 3 months.
For patients undergoing treatment for head and neck cancer, this study will use dynamic contrast-enhanced CT scans to try to determine which lymph nodes in the neck contain cancer and require surgical removal.
The purpose of this study is to determine how safe and how well POL-103A works in preventing the relapse of melanoma after patients who have undergone surgery.
The goal of this trial is to test the impact of a step-wise approach for catheter ablation of recurrent ventricular tachycardia, (irregular heart rhythms that originate in the bottom chambers of the heart), in patients with a previous heart attack for whom catheter ablation is clinically indicated.
This study is being offered to patients who have hormone resistant prostate cancer (HRPC). This means that their prostate cancer is no longer responding to standard hormonal therapy. The purpose of this study is to determine whether Degarelix will be able to stop the PSA from rising in patients with hormone resistant prostate cancer.
This prospective blinded study will assess the diagnostic capability of an informatics enhanced SNP based technology (Parental Support) to identify pregnant women who are carrying a fetus with an aneuploidy from fee floating DNA in the maternal blood.
The purpose of this study is to investigate the effectiveness and safety of the drug Gleevec (imatinib) as a new treatment for patients with active diffuse scleroderma. This drug has not been used previously to treat scleroderma, but it has been found to advance the treatment and life span of patients with a type of leukemia called chronic myeloid leukemia or CML. Gleevec acts on chemical signals in the cells that may decrease fibrosis (the hardening of the skin that occurs in scleroderma). It works by interfering in the process that activates many molecules that cause fibrosis, including TGFbeta (which may be a key part of disease activity in scleroderma). This study proposes to treat patients that have significant diffuse scleroderma with Gleevec for 6 months and investigate several measures of scleroderma disease activity before, during and at the end of treatment (0, 3 months and 6 months). This is a randomized, double blind, placebo-controlled trial: 20 patients will be divided into two groups in a 4:1 ratio, with 16 patients taking 400mg of Gleevec per day and 4 taking a placebo. The differences between the groups that will be measured include safety, Modified Rodnan skin score (mRSS), Health Assessment Questionnaire (HAQ), global assessments (100mm VAS) and changes in biomarkers in blood and skin biopsies.
The purpose of this study is to characterize the safety, efficacy and dose response of BMS-945429 in subjects with moderate to severe Crohn's disease and who have had an insufficient response to conventional therapy or have failed Anti-Tumor Necrosis Factor (anti-TNF) therapy.
