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.
Tranexamic acid (TXA) is an antifibrinolytic agent that has been shown to reduce blood loss and blood transfusion requirements in the following patient populations: multisystem trauma, liver transplantation, cardiac surgery and spine surgery. Patients undergoing major liver resection are at risk of severe perioperative blood loss and may also benefit from perioperative TXA administration. This open label, non-randomized study to evaluate the pharmacokinetic and pharmacodynamic properties of two well studied dosing regimens of TXA will provide guidance in determining the optimal TXA dosing regimen for patients undergoing major liver resection. Compelling evidence of the effectiveness of TXA comes from the large multicentred, multi-national CRASH-2 trial where TXA was administered as a 1 g bolus + 1 g infusion over 8 hours. In liver transplant surgery, the following dose regimen has been shown to have great effect:10 mg/kg/h from the start of surgery until 2 hours after reperfusion of the liver transplant. Although TXA is not currently approved for use in patients undergoing major liver resection, Health Canada has allowed the use of tranexamic acid for use in this research study.
Post-partum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most common uterotonic drug used to prevent and treat PPH in North America, however, there are some limitations to its use. Oxytocin has a very short duration of action, which requires a continuous infusion to achieve sustained uterotonic activity. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recently recommended a single 100mcg dose of carbetocin at elective Cesarean delivery to promote uterine contraction and prevent post partum hemorrhage (PPH), in lieu of the more traditional oxytocin regimens. Carbetocin lasts 4 to 7 times longer than oxytocin, with a similar side effect profile and apparent greater efficacy rate. However, a dose response study to determine the minimum effective dose of carbetocin has not yet been published. The investigators hypothesize that the minimum effective dose (ED90) is at least 20mcgs (or perhaps below) in women undergoing elective Cesarean delivery.
Currently, standard wound care practice is suboptimal at assessing wound remodeling and bacterial infection in real-time. An alternative and complimentary means of providing real-time imaging of connective tissue re-modeling and bacterial infection may greatly increase the early detection of infection thus leading to rapid therapeutic intervention. Our new device, PRODIGI(TM), images tissue and bacterial autofluorescence (without agents) and may provide this clinically-important capability. In preliminary preclinical testing, the investigators have discovered that when wounds are illuminated by violet/blue light, endogenous collagen in the connective tissue matrix emit a characteristic green fluorescent signal, while most pathogenic bacterial species emit a unique red fluorescence signal due to the production of endogenous porphyrins. Therefore, with autofluorescence imaging, no exogenous contrast agents are needed during imaging, making this approach particularly appealing as a diagnostic imaging method for clinical use. The investigators hypothesize that real-time imaging of tissue autofluorescence signals emanating from endogenous connective tissue (e.g. collagen) and pathogenic bacteria within complex wounds can be used to determine healing status (i.e., collagen re-modeling and wound closure), detect wound bacterial contamination and/or infection that is occult under standard clinical white light evaluation, and guide intervention and wound care.
This study will assess the serum uric acid lowering effects and safety of lesinurad over a long-term timeframe.
Forty percent of patients that require dialysis for kidney failure die within three years mostly due to heart disease. Heart failure and high blood pressure are common problems in patients that require dialysis and are key causes of death due to heart disease. Eplerenone is a drug that is very effective at improving heart failure and reducing blood pressure in patients that do not require dialysis. There is currently no evidence to tell physicians whether eplerenone would have similar benefits in patients that require dialysis. This evidence can only be reliably generated by performing a large scale study. Before such a study is undertaken, the investigators must determine whether eplerenone will be well tolerated and safe in patients that require dialysis. The investigators will perform an initial small trial called the Pilot trial in Hemodialysis patients undergoing Aldosterone antagoniSm with Eplerenone (PHASE) to determine if eplerenone is a well tolerated, safe medication to use in a very large, global study that will show whether or not eplerenone reduces important outcomes for patients like death from heart causes.
This multicenter, randomized, open label parallel-group study will evaluate the efficacy and safety of subcutaneous versus intravenous MabThera/Rituxan (rituximab) in combination with CHOP chemotherapy in patients with previously untreated CD20-positive diffuse large B-Cell lymphoma. Patients will be randomized to receive either MabThera/Rituxan 1400 mg subcutaneously or MabThera/Rituxan 375 mg/m2 intravenously on Day 1 of each cycle for 8 cycles, in combination with 6-8 cycles of CHOP chemotherapy. Anticipated time on study treatment is 6 months.
This study assessed the efficacy and safety of secukinumab in patients with active ankylosing spondylitis who were tolerant to or had an inadequate response to NSAIDs, DMARDs and / or TNFα inhibitor
The aim of this study is to investigate the efficacy and safety of two doses (high and low) of empagliflozin as add-on therapy to metformin in patients with type 2 diabetes mellitus (T2DM) and insufficient glycaemic control. Both doses may be given once daily or split to a twice daily dosage. This results in 4 different dosage regimens of empagliflozin (high dose once daily or split vs. low dose once daily or split). This is done to evaluate whether a twice daily dose regimen of empagliflozin results in a loss of efficacy relative to once daily dosing when given on top of metformin background therapy.
Many patients with chronic obstructive pulmonary disease (COPD) also have other diseases referred to as comorbidities. Often these patients require health care by a variety of health care professionals from services linked to hospitals and in the community. Unfortunately, sometimes it may be difficult for these patients to receive appropriate care in a timely manner resulting in a trip to the emergency department. As well, patients may benefit from education that enables them to recognize early signs indicating they are getting sicker and to self-manage their disease. Our study will examine a strategy that includes a case manager who will make weekly phone contact with COPD patients with comorbidity that present either to the emergency department or are admitted to hospital. Weekly contact will focus on teaching patients to recognize worsening symptoms and self-management strategies. The case manager will work with patients, caregivers, community health care providers and hospital specialists to promote communication and optimize care delivery. The investigators will examine the impact of our intervention on the need for emergency department visits and hospital admission. The investigators will also examine the impact on patients' health related quality of life, number of COPD exacerbations, and disease progression.
Life-threatening infections account for 10% of all intensive care unit admissions and constitute the second more frequent cause of death in the ICU after heart diseases. The most common cause of death in patients admitted with life-threatening infections is multi-organ failure that is mediated by severe inflammation. Given the relationship between inflammation and blood clotting, blood-thinners (also called anticoagulants) have been used to decrease inflammation and the formation of small clots. Several lines of evidence suggest that heparin, a proven and inexpensive blood-thinner, may reduce improve survival in patients diagnosed with life-threatening infection. The primary objective of this study is to demonstrate the feasibility of enrolling patients in a large randomized controlled trial investigating heparin in patients with severe infections. In this study, patients with life-threatening infections will have an equal chance of receiving an intravenous infusion of heparin, or a low dose of a similar drug to prevent of blood clots while patients are immobile. The primary purpose of the study is to demonstrate that an average of 2 patients per site, per month, can be enrolled. Other measures of feasibility include the consent rate, the number of protocol violations that occur during the trial, and the number of dose reductions needed due to excessive anticoagulation. To study the biologic effects of heparin in patients with severe infection, specific laboratory markers will be measured and analyzed. If the feasibility of the trial is confirmed, a large randomized trial designed to tell if heparin can safely improve survival will be conducted. Given its low cost and availability, if heparin is shown to improve survival in patients with severe infection, adoption of this therapy on a global scale is anticipated.
