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.
Hypomagnesemia (hMg) is a common side effect of important anti-cancer therapies such as epidermal growth factor receptor inhibitors (EGFRIs) and platinum-containing anti-cancer drugs. EGFRIs, including cetuximab (cmab) and panitumumab (pmab), have been estimated to cause hMg in over 18% and 27% of patients respectively1, while 90% of patients receiving cisplatin will develop hMg if left untreated. The development of severe hMg may result in increased symptoms such as fatigue, neuromuscular changes, mental status changes and cardiac arrhythmias which could result in treatment delays and may compromise treatment efficacy. Despite the common occurrence of this toxicity, little is known regarding the optimal magnesium management strategy. As physicians do not know what the "best" treatment for patients is, genuine uncertainty ("clinical equipoise") exists. Physicians will choose between different "standards" of magnesium replacement in their personal practice, using idiosyncratic decision making processes, without the physician or the patient knowing the optimal option. This is not good for patients, physicians and society as a whole. Determining the optimal treatment remains an important medical issue for patients, physicians and society. This study will use a novel method to allow comparisons of established standard of care prophylactic treatment using the "integrated consent model" as part of a pragmatic clinical trial7. By integrating medical and clinical practices, physicians will be able to inform their patients about the randomized control trial, akin to a typical conversation between the physician and patient, without written informed consent. This clinical interaction would then be documented, as ordinarily done in practice. Medical and clinical practice will be intertwined with the patients' welfare at the forefront of our best interests.
This main purpose of this clinical study is to learn about the safety and activity of margetuximab and pembrolizumab combination treatment in patients with HER2+ gastric and gastroesophageal junction cancer.
GSK1278863 is an orally available, hypoxia-inducible factor - prolyl hydroxylase inhibitor, currently being investigated as a treatment for anemia associated with chronic kidney disease. GSK1278863 has been given as a once daily regimen in clinical studies to date. However, physicians in countries that use a three-times weekly hemodialysis schedule prefer to give the anemia medicine at the same time as the dialysis session. This study will test how well GSK1278863 can maintain hemoglobin levels when given three-times weekly, for 29 days. This study will describe the relationship between hemoglobin and GSK1278863 given three-times weekly. The data from this study will allow for conversion of once daily doses to three-times weekly doses.
This phase IV clinical study trial will be conducted among persons who require treatment for LTBI treatment in Iqaluit, Nunavut and Ottawa, Ontario. The primary objective of this study is to compare the proportion of people who complete directly observed prophylactic treatment (DOPT) using the new 3HP regimen to the current standard of 9 months INH.
In the REaCT-Vascular Access Her2 negative study, the investigator will use a novel method to allow comparisons of established standard of care vascular access strategies using the "integrated consent model" as part of a pragmatic clinical trial. Determining the optimal vascular access strategy remains an important medical issue for patients, nurses, physicians and society. A novel method to allow comparison of established standards of care is needed as part of an increasing internationally mandated incentive to perform more pragmatic clinic trials.
This is an open-label, multicenter, biomarker study designed to be hypothesis-generating in order to better understand the mechanism of action of ocrelizumab and B-cell biology in RMS or PPMS. The study will be conducted in two cohorts i.e. RMS cohort (4 arm group) and PPMS cohort (one arm group). RMS cohort: Ocrelizumab will be administered as two intravenous (IV) infusions of 300 milligrams (mg) on Days 1 and 15. Subsequent doses will be given as single 600-mg infusions at Weeks 24 and 48. Participants will be randomized in 1:1:1 ratio to receive lumbar puncture (LP) post-treatment at Week 12, 24, or 52 following the first dose of ocrelizumab in three arm groups. A fourth RMS arm with delayed treatment start (Arm 4 [control group]) will not be a part of the randomization and will be recruited separately, wherein treatment with ocrelizumab will be delayed for 12 weeks from pre-treatment baseline. PPMS cohort: Ocrelizumab 600 mg will be administered as two 300-mg IV infusions separated by 14 days at a scheduled interval of every 24 weeks. Participants will receive a LP at the start of the study before dosing with ocrelizumab and second LP at Week 52 following the first dose of ocrelizumab. A long-term extension will be conducted for participants that complete the study and continue to receive ocrelizumab. Treatment with ocrelizumab in the entire study will continue for approximately 4.5 years after the first infusion.
Triple-negative breast cancer (TNBC) is a term applied to breast cancer cases that have <1% expression of the estrogen receptor (ER) and the progesterone receptor (PR) and do not over express HER2. TNBC is diagnosed in 15-20% of breast cancer cases and tends to occur in younger women and have biologically more aggressive high grade disease. Clinically, patients with TNBC have a poorer prognosis compared to patients diagnosed with other breast cancer subtypes. Because of the aggressive phenotype and due to observations that systemic chemotherapy offers significantly higher benefit in ER negative disease, current treatment guidelines from provincial and other organizations recommend that patients receive adjuvant systemic chemotherapy for any TNBC greater than 0.5 cm in greatest diameter or node positive independent of primary tumor size. Currently, there is no world-wide standard recommended chemotherapy regimen for the management of TNBC in the neoadjuvant/adjuvant setting, with treatments varying from region and institution. As physicians do not know what the "best" treatment for patients is, genuine uncertainty ("clinical equipoise") exists. Physicians will choose between different "standards" in their personal practice, using idiosyncratic decision making processes, without the physician or the patient knowing the optimal option. This is not good for patients, physicians and society as a whole. Determining the optimal treatment remains an important medical issue for patients, physicians and society. This study will survey opinions on a novel method to allow comparisons of established standard of care prophylactic treatment using the "integrated consent model" as part of a pragmatic clinical trial and attempt to compare head to head standard chemotherapy regimens in patients with TNBC.
Osteoarthritis (OA) of the knee is the most frequent cause of knee pain after the age of 50 years. OA is a joint disease characterised by articular cartilage loss associated with structural changes in the cartilage and adjacent structures. The main symptoms are pain and functional disability. The goals of OA therapy are to decrease pain and maintain or improve joint function. There is evidence that diacerein has both a symptomatic and a structural effect on cartilage, and clinical studies suggest that diacerein therapy significantly decreases OA symptoms when compared to placebo. Diacerein has been shown to inhibit interleukine-1 (IL-1β), and down-regulated IL-1β stimulated secretion of metalloproteinases and aggrecanases, and thereby prevent breakdown of cartilage by these enzymes. Diacerein has no effect on the synthesis of prostaglandins, and therefore no effect on the upper intestinal tract. The purpose of this phase III-IV international, multicentre, double-blind, non-inferiority, randomised, controlled study is to determine the efficacy and safety of diacerein vs. celecoxib on symptoms after 6 months of treatment, and on structural changes after 2 years of treatment in knee OA patients as assessed by magnetic resonance imaging (MRI).
The purpose of this study is to evaluate canagliflozin use in the treatment of type 2 diabetes mellitus (T2DM) and generate evidence of its effectiveness, safety and patient-reported outcome (PRO) in a usual clinical practice in Canada.
Falls have significant consequences for older adults, including fracture, disability, and death (1). Risk factors for falls include both impaired physical and cognitive function (1). Thus, older adults with chronic stroke are at significant risk for falls (2). Exercise is an evidence-based approach for reducing falls risk, even among those who are living with stroke-related impairments (3,4). More recently, mindfulness based meditation is gaining recognition for its positive impact on both physical and cognitive health (6,7). Thus, the investigators hypothesize that combining exercise with mindful meditation may be greater impact on falls risk reduction as compared with exercise alone. To begin exploring our hypothesis, we will conduct a 12-week proof-of-concept study among 20 older adults with chronic stroke (i.e., suffered their first clinical stroke > or = 12 months prior to study entry). Participants will be randomly allocated to either: 1) exercise; or 2) exercise + mindfulness based meditation. Outcomes will include measures of mobility, balance, and cognitive function. 1.
