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.
Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Infection by certain high-risk oncogenic types of HPV (HR-HPV) is the major cause of several cancers in men, notably squamous cell carcinoma (SCC) of the anal canal. Rates of anal infection with these HR-HPV strains and the resultant high-grade anal dysplasia and anal cancer are much higher in men who have sex with men (MSM) than in the general population. Co-infection with human immunodeficiency virus (HIV) further amplifies this burden, making the rates of anal SCC in HIV-positive MSM higher than the historic rates of cervical cancer prior to the adoption of routine cervical cytology screening. Despite these alarming statistics, there are no established protocols for optimal screening and treatment of anal HPV and cancer precursors, nor has there been any widespread rollout of organized screening programs anywhere in Canada. Further, not only does HPV directly cause significant disease in these men, but there is growing epidemiologic evidence that HPV infection may enhance sexual transmission of HIV. These significant knowledge gaps translate into fundamental deficiencies in care for HIV-positive MSM. The HPV Screening and Vaccine Evaluation in MSM (HPV-SAVE) study team will recruit a large group of MSM from various Ontario and Vancouver clinics, in order to carry out a number of different studies. The HPV-SAVE team brings together community and internationally-recognized experts in HPV and HIV disease and mucosal immunology, to better define the optimal approaches for primary and secondary prevention and treatment of HPV-associated anal disease among HIV-positive MSM, and to explore biological mechanistic evidence regarding the potential role of HPV as a co-factor for HIV transmission. This will yield critical information which can lead to improvement in the health of MSM, and will provide a foundation on which to build further, large-scale screening and treatment trials on a national level. The primary aim of the current study is to systematically compare ablative therapy versus intensive observation alone (also known as 'watchful waiting') in outcomes relating to high-grade anal dysplasia.
Prospective, randomized, placebo controlled, phase II clinical study of subjects crossing over from an approved inhaled antibiotic to inhaled nitric oxide as compared to a placebo control arm.
The purpose of the study is to collect and assess long term data on the safety, tolerability, and efficacy of pridopidine in patients with Huntington's disease (HD).
This randomized phase II study aims to investigate whether the addition of bevacizumab to standard corticosteroid therapy results in greater improvement in symptoms and less treatment-induced symptoms compared with standard corticosteroid therapy for patients with symptomatic brain radionecrosis following radiosurgery. It is hypothesized that the addition of bevacizumab to standard care corticosteroids will reduce treatment-induced toxicities and improve neurologic impairments in patients with brain radionecrosis following radiosurgery for brain metastases.
The purpose of this study is to evaluate the efficacy, safety and pharmacokinetics of HM61713 in patients with T790M-positive non-small cell lung cancer (NSCLC) after treatment with an epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI).
Sulfonylurea are known to be associated with a risk of hypoglycaemia. However, little is known about the real frequency of asymptomatic or unreported hypoglycemia and their impact on glycemic control and quality of life among patients using sulfonylureas (SUs). The frequency of hypoglycemia is probably underestimated since self-monitoring of blood glucose (SMBG) fail to identify asymptomatic episodes, especially among patients with higher risk of hypoglycemia unawareness (longer diabetes duration, elderly, recurrent hypoglycemia, etc.). No previous studies have reported total hypoglycemia as measured by continuous glucose monitoring system (CGMS) in a large group of Canadians, therefore underestimating the true incidence of these events. As with age hypoglycemia perception is reduced and consequences can be increased due to frailty, elderly could be especially sensitive to the risk of hypoglycemia. Documentation of the total number of hypoglycemia is a relevant objective to really appreciate the potential impact of SUs in the Canadian context. The investigators propose a multicenter observational prospective study in order to study the incidence of hypoglycaemia measured by CGMS among patients with type 2 diabetes mellitus (T2DM) newly prescribed a SU. The investigators propose to perform a baseline testing (pre-initiation of the SU), at initiation (first week after the first dose of the SU) and after a 3 months follow-up of treatment, including medical history measures, quality of life and diabetes treatment satisfaction. In patients with T2DM not at goal (A1c >7.0 mmol/L), and newly prescribed a SU, the objectives and hypotheses of the study are to estimate the incidence rate of hypoglycaemia as measured by continuous glucose monitoring system (CGMS) over a total of 3 weeks period following the initiation of the SU.
The primary objective of the study is to evaluate the efficacy of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) score as compared with placebo in participants with early AD. Secondary objectives are to assess the effect of monthly doses of aducanumab as compared with placebo on clinical progression as measured by Mini-Mental State Examination (MMSE), AD Assessment Scale-Cognitive Subscale (13 items) [ADAS-Cog 13], and AD Cooperative Study-Activities of Daily Living Inventory (Mild Cognitive Impairment version) [ADCS-ADL-MCI].
The purpose of the present study is to evaluate the safety and efficacy of Brainsway Deep TMS (DTMS) for the treatment of PTSD.
This study seeks to better characterize relationships between visual function and the progression (worsening) of geographic atrophy (GA) due to age-related macular degeneration (AMD). The study is also intended to generate new information on the relationship between genetics and GA progression. This is a global, prospective, multicenter, epidemiologic study enrolling participants with GA secondary to AMD. The study visits are scheduled to occur every 6 months. The anticipated duration of the study is up to 48 months. There is a planned interim analysis around the 2-year time window for the study.
In a previous study, the investigators established the dosage of foetal glycated hemoglobin (FGH). It represents the mean of blood sugar 4-6 before the delivery. The investigators also compared the FGH of newborn of women with and without gestational diabetes mellitus (GDM) and determined that newborn of women with GDM had significantly higher FGH that newborn of women without GDM. In this study, the investigators want to compare the FGH of newborn of GDM women randomized to a group reaching the Canadian Diabetes Association recommended blood glucose objectives treatment (fasting: 5.3 mmol/L and 2-hour after meals: 6.7 mmol/L) to a group reaching lower blood glucose objectives (fasting: 4.8 mmol/L and 2-hour after meals: 5.9 mmol/L)
