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 purpose of this study is to establish the safety profile of oral (by mouth) abiraterone acetate and oral prednisone following short-term administration after standardized low-fat or high-fat meals to patients with metastatic (spreading) castration-resistant prostate cancer (mCRPC).
The purpose of this study is to assess the pharmacodynamic (PD) effects (Total Symptom Score (TSS) and its individual components: rhinorrhoea, nasal congestion, post-nasal drip) of intranasal, repeat dose SB-705498 in non-allergic rhinitis (NAR) patients elicited by a cold dry air challenge in an environmental exposure chamber (EEC). SB-705498 is a selective antagonist of the transient receptor potential vanilloid-1 (TRPV1) ligand gated ion channel. TRPV1 is a cation permeable ion channel that can be activated by several physiological factors, such as heat, protons (pH), osmotic stress, eicosanoid derivatives, anandamide, and by products of inflammation, such as histamine, prostaglandins and bradykinin. In the nose, the local TRPV1 expressing sensory C-fibres are thought to play a key role in the development of nasal hyper-responsiveness to environmental provocateurs. It has been proposed that blocking the nasal sensory nerve stimulation may control nasal hyper-responsiveness and therefore prevent the induction of rhinitis symptoms. In this context, preclinical evidence supports that targeting TRPV1 by SB-705498 may be an attractive option. In this study NAR patients will be randomised, in a double blind, placebo controlled cross over design to receive 14 day repeat doses of 12mg intra-nasal SB-705498 once daily. Whilst dosing at home, subjects will record symptom scores to document their symptoms. In addition, during visits to the clinical unit, acoustic rhinometry, quality of life questionnaires and safety assessments will be monitored.
The study objective is to compare the cost-effectiveness of VCE to push enteroscopy in patients with gastrointestinal bleeding of obscure origin with a negative initial work-up.
A growing body of evidence suggests that individuals with chronic lung disease have important deficits in balance control that may be associated with an increased risk of falls. The main purpose of this study is to examine the effects of a balance training program on measures of balance and fall risk in people with chronic lung disease.
Syncope affects about 50% of Canadians, is the cause of 1 - 2% of all emergency room visits, and probably is responsible for CDN $250 million in health care spending each year. It is associated with decreased quality of life, trauma, loss of employment, and limitations in daily activities. It is a particular problem for older people, partly because of increased frailty, and partly because of a difficult differential diagnosis. One of the causes in older adults is intermittent complete heart block in the setting of bifascicular heart block, but they may also faint due to a variety of tachyarrhythmias, sick sinus syndrome, and several neurally mediated syncopes. Often treatment decisions should be made before the true cause is apparent.
A prospective population-based cohort study is being conducted in Ontario to evaluate whether the performance of Oncotype DX® changes the treatment recommended and the treatment received in women or men with node negative, ER positive breast cancer who are receiving (or will receive) endocrine therapy and who are candidates for chemotherapy. One thousand eligible consenting women and men will have their tumor tissue specimen sent to Genomic Health where the Oncotype DX® assay will be performed.
The purpose of this study is to compare the toxicity of two new radiation schedules for the treatment of prostate cancer. Patients will be randomized to receive 5 treatments delivered every other day over 11 days, or once per week over 29 days. Both of these schedules are shorter than the standard treatment which is usually 39 treatments over 8 weeks.
In moderate to high risk patients, cardiovascular complications after surgery account for almost 60% of death after surgery. This study will randomize 140 patients into routine postop care with Holter monitoring versus routine postop care + remote ST monitoring + Holter monitoring. The response time to electrocardiographic (ECG) ST changes as well as the total ischemia time will be studied.
The primary objective of this study is to demonstrate the equivalence of rMenB+OMV NZ lot 1 to rMenB+OMV NZ lot 2 when administered to adolescents, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by ELISA geometric mean concentrations (GMCs) against vaccine antigen 287-953, approximately 30 days after a primary vaccination course of two doses administered one month apart.
The myeloproliferative neoplasms (MPN), most notably polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are a diverse but inter-related suite of clonal disorders of pluripotent hematopoietic stem cells (Tefferi et al., 2008). The MPN share a range of biological, pathological, and clinical features including the relative overproduction of one or more cells of myeloid origin, growth factor independent colony formation in vitro, marrow hypercellularity, extramedullary hematopoiesis, spleno- and hepatomegaly, and thrombotic and/or hemorrhagic diatheses (Tefferi et al., 2005). This is a multi-centre, open-label, non-randomized, dose-escalation study, to be conducted in two phases: a dose-escalation phase (Part 1), to determine the safety and tolerability of momelotinib (CYT387), and to identify a therapeutic dose for the expanded cohort; and a dose-confirmation phase (Part 2), which will be a cohort expansion at or below the MTD of momelotinib. In the Part I dose-escalation phase of the study, subjects will be assigned to dose levels in successive cohorts starting with a dose in the first cohort of 200 mg BID (twice daily with doses taken approximately 12 hours apart). Doses will be escalated by 50 mg BID per cohort until dose-limiting toxicities are observed. The dose level at which ≥2 of 6 subjects develop a first cycle dose-limiting toxicity (DLT) is defined as the DLT level. The maximum tolerated dose (MTD) is defined as the dose level below the DLT level. New dose levels may begin accrual only if all subjects at the current dose level have been observed for a minimum of 28 days from the first day of treatment. The dose level chosen for study in the dose confirmation phase of the study will be the MTD or a lower dose shown to have significant clinical activity (efficacy) as determined by the safety review committee. Subjects will be evaluated weekly for the first cycle, every 2 weeks during cycle 2, then monthly for 4 cycles for a total of 6 cycles. In the dose-confirmation phase of the study, approximately fifty (50) subjects will be treated at the MTD or at a lower dose shown to have significant clinical activity (efficacy) as chosen by the Safety Review Committee. In the dose confirmation phase of the study subjects will be evaluated every 2 weeks during the first treatment cycle, and then monthly for 5 cycles for a total of 6 cycles.
