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.
Intra-uterine insemination (IUI), generally in combination with ovarian stimulation, is one of the most commonly used treatments for infertility. Accurate timing of insemination, in order to coincide with ovulation, has an important impact on the success rate. Optimal timing of insemination is achieved either by monitoring follicular growth through serial ultrasound measurements followed by the administration of human chorionic gonadotropin (hCG) or by the detection of urinary luteinizing hormone (LH). However in cycles where follicular growth is monitored there is a possibility of premature LH rise before the administration of hCG, which may affect the outcome of the treatment. The goal of the study is to determine if adding the testing of urine LH in conjunction with ultrasound monitoring leads to an increase in pregnancy rates in IUI cycles when compared to ultrasound monitoring alone.
INTRODUCTION: There is an important need for inexpensive drugs that treat neuropathic pain. Early research suggests that methadone may be a good, inexpensive drug to treat neuropathic pain. Methadone is available in a low cost powder that is easily prepared for different routes of administration. This study will look at the effect and safety of methadone compared to the regular treatment of morphine for the treatment of chronic neuropathic pain. OBJECTIVES: First the investigators want to determine if methadone is effective and safe for the treatment of neuropathic pain. Since a placebo control group would be unethical, the proposed comparator will consist of the "gold standard" conventional treatment, controlled release morphine. The investigators will compare methadone to controlled-release morphine with regard to how it affects the level of pain and extent of side effects. Next the investigators want to examine safety as well as to determine whether methadone leads to improvements in physical and emotional functioning, and participants' satisfaction with the treatment. METHODS: A double blind, randomized trial comparing methadone and controlled release morphine is proposed. After 1-week, participants will be randomly assigned to either methadone or controlled release morphine and will gradually build to a dose at which they receive adequate pain relief without unacceptable levels of side effects. This 5-week phase will be followed by a 6-week dose phase and then a 4-week tapering off phase. Study drug: The study drug is methadone supplied in 2.5 mg tablets. The comparator will consist of controlled release morphine in 10 mg tablets. The dose of each will range from 1-12 tablets taken every 12 hours (dose ranges methadone 5-60 mg/day, controlled release morphine 20-240 mg/day). Setting: This is a 3-site study involving pain clinics in Halifax, Nova Scotia; London, Ontario; and Calgary, Alberta.
Background: Endovascular thrombolysis, with or without mechanical clot removal (ET), may be beneficial for a subgroup of patients with cerebral venous sinus thrombosis (CVT), who have a poor prognosis despite treatment with heparin. Published experience with ET is promising, but only based on case series and not on controlled trials. Objective: The main objective of the TO-ACT trial is to determine if ET improves the functional outcome of patients with a severe form of CVT Study design: The TO-ACT trial will be designed as a multi-centre, prospective, randomized, open-label, blinded endpoint (PROBE) trial. Study population: Patients are eligible if they have a radiologically proven CVT, a high probability of poor outcome (defined by presence of one or more of the following risk factors: mental status disorder, coma, intracranial hemorrhagic lesion or thrombosis of the deep cerebral venous system) and the responsible physician is uncertain if ET or standard anti-coagulant treatment is better. Intervention: Patients will be randomized to receive either ET or standard therapy (therapeutic doses of heparin). ET consists of local application of alteplase or urokinase within the thrombosed sinuses, and/or mechanical thrombectomy. Glasgow coma score, NIH stroke scale and relevant laboratory parameters will be assessed at baseline. Endpoints: The primary endpoint is the modified Rankin scale (mRS) at 12 months. The most important secondary outcomes are the mRS, mortality and recanalization rate at 6 months. Major intra- and extracranial hemorrhagic complications within one week following the intervention are the principal safety outcome. Results will be analyzed according to the "intention-to-treat" principle. Assessment of study endpoints will be carried out according to standardized questionnaires by a blinded neurologist or research nurse who is not involved in the treatment of the patient. Study size: To detect a 50% relative reduction in mRS≥2 (from 40 to 20%), 164 patients (82 in each treatment arm) have to be included (two-sided alpha, 80% power). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Included patients may benefit directly from ET. Complications of ET, most notably intracranial hemorrhages, constitute the most important risk of the study.
The primary purpose of the study is to evaluate the safety and PK profile of CC-930 in idiopathic pulmonary fibrosis patients.
The purpose of this study is to determine whether long-term treatment with a beta-blocker (BB) such as atenolol and/or an angiotensin receptor blocker (ARB) such as telmisartan, given to adult patients with bicuspid aortic valve (BAV) disease (aortopathy) reduces the widening (dilatation) of the aorta from its baseline size.
Acoustic Neuromas (otherwise known as Vestibular Schwannoma -VS) are benign tumors which grow on the hearing nerve and can cause progressive hearing loss and compression of vital brain structures and even death if it continues. The primary objective of this study is to evaluate the efficacy of Nilotinib in the treatment of patients with progressing VS. Secondary objectives of this study is to evaluate the toxicity profile, quality of life and symptom management of Nilotinib in the treatment of patients with progressing VS.
This is a phase 3 randomized, active-controlled, open-label, multicenter study that will be conducted in approximately 120 investigational sites worldwide. Subjects with either recurrent or refractory NMIBC (Ta high grade, T1 low or high grade, CIS) will be eligible for participation in this study. Refractory disease is defined as evidence of persistent high grade bladder cancer (Ta HG, T1, and/or CIS) at least 6 months from the start of a full induction course of BCG with or without maintenance/re-treatment at 3 months. Recurrent disease is defined as reappearance of disease after achieving a tumor-free status by 6 months following a full induction course of BCG with or without maintenance/re-treatment at 3 months. Subjects with recurrent disease must have recurred within 18 months following the last dose of BCG. Approximately 450 subjects will be randomized. The primary objective of this study is to evaluate the efficacy of intravesical EN3348 as compared with mitomycin C in the treatment of subjects with recurrent or refractory NMIBC. The secondary objective is to evaluate the safety of EN3348 as compared with mitomycin C in the treatment of subjects with BCG recurrent or refractory NMIBC. This study will consist of 4 phases: Screening, Induction, Maintenance and Follow-Up and will be conducted over 3 years.
Balloon angioplasty is used to open up a narrowing that forms in hemodialysis fistula. Two areas of particular problems are the terminal portion of the cephalic vein near the shoulder and the central veins in the chest. Although angioplasty is standard of care the treated narrowed segments of vein mostly renarrow within 3 months requiring retreatment to keep your dialysis access functional. Recently there has been introduction of a new technology called a covered stent graft. Initial studies suggest that placing this device across the area of narrowing leads to dialysis access staying open longer and needing less angioplasty treatments. This study is designed to compare angioplasty (standard of care) versus using a covered stent graft. The investigators will then look at the dialysis records and future fistulograms to see if there is decreased flow through the fistula at 3, 6 and 12 months after the initial procedure.
This study is designed as a 2-part study, with Part 1 being open-label to best determine the appropriate dose levels to use in Part 2, which has a randomized, double-blind, placebo controlled design. The study aims to assess the safety and tolerability of BGS649, and determine whether or not BGS649 is able to normalize testosterone levels and improve insulin sensitivity in obese, hypogonadotropic hypogonadal (OHH) men
This was a multi-center, parallel, active comparator controlled, open-label, randomized (1:1) phase III study of single agent ofatumumab compared to single agent rituximab in subjects with rituximab-sensitive indolent B-cell non hodgkin lymphoma that has relapsed at least 6 months after completing treatment with single agent rituximab or a rituximab-containing regimen. Subjects must have attained a Complete Response or Partial Response to their last prior rituximab containing therapy lasting at least six months beyond the end of rituximab therapy. Subjects were to receive four weekly doses of single agent ofatumumab (1000 mg) or rituximab (375 mg/m2), followed by ofatumumab (1000 mg) or rituximab (375 mg/m2) every 2 months for four additional doses. Therefore, subjects were to receive a total of eight doses of anti-CD20 antibody over 9 months. Subjects were evaluated for response after completion of the first four doses of therapy, after six doses of therapy, and after completion of study therapy. Subjects were to be followed until the end of the designated follow-up period (total study duration of 200 weeks) or until they meet the withdrawal criteria. The primary objective of the study OMB157D 2303 was to demonstrate the efficacy of Arzerra based on the primary endpoint (Progression-free survival (PFS) as assessed by the IRC) in patients with Indolent B-cell Non-Hodgkin's Lymphoma Relapsed After Rituximab-Containing Regimen. The Independent Data Monitoring Committee (IDMC) met on November 22, 2015 and recommended the termination of the study due to futility (cut-off date = 12Jun2015). The IDMC reviewed analyses results for progression free survival (PFS), overall response rate (ORR), and overall survival (OS). Novartis accepted this recommendation and the study was closed. Final analysis was performed (cut-off date =19 Dec 2016). As the study was stopped for futility, the primary objective was not met and some secondary endpoints, supportive of primary objective (Duration of Response (DOR), time to next therapy, and pharmacokinetics) were removed as secondary end points.
