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 reason for the study is to find out if an experimental combination of an oral medication called osimertinib (TAGRISSO®) when used in combination with chemotherapy is more effective than giving osimertinib alone for the treatment of locally advanced or metastatic non-small cell lung cancer. Some lung cancers are due to mutations in the Deoxyribonucleic acid (DNA) which, if known, can help physicians decide the best treatment for their patients. One type of mutation can occur in the gene that produces a protein on the surface of cells called the Epidermal Growth Factor Receptor (EGFR). Osimertinib is an Epidermal Growth Factor Receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets Epidermal Growth Factor Receptor (EGFR) mutations. Unfortunately, despite the benefit observed for patients treated with osimertinib, the vast majority of cancers are expected to develop resistance to the drug over time. The exact reasons why resistance develops are not fully understood but based upon clinical research it is hoped that combining osimertinib with another type of anti-cancer therapy known as chemotherapy will delay the onset of resistance and the worsening of a patient's cancer. In total the study aims to enroll approximately 586 patients, consisting of approximately 30 patients who will participate in a safety run-in component of the trial, and approximately 556 who will receive osimertinib alone or osimertinib in combination with chemotherapy in the main trial. In the main part of the trial there is a one in two chance of receiving osimertinib alone, and the treatment is decided at random by a computer. The study involves a Screening Period, Treatment Period, and Follow up Period. Whilst receiving study medication, it is expected patients will attend, on average, approximately 15 visits over the first 12 months and then approximately 4 visits per year afterwards. Each visit will last about 2 to 6 hours depending on the arrangement of medical assessments by the study centre.
This is an open-label, multicenter, Phase 1/2 study evaluating the safety and efficacy of CTX110 in subjects with relapsed or refractory B-cell malignancies.
Intravitreal injection (IVI) is an ophthalmological procedure used worldwide to treat ocular conditions. Its use has been steadily increasing for several years, because this method of drug delivery minimizes systemic exposure and allows for intraocular drug levels not achievable through systemic or topical drug administration. IVI of agents such as anti-vascular endothelial growth factor (anti-VEGF) or corticosteroids are efficacious for several retinal diseases, including age-related macular degeneration, macular edema due to retinal vein occlusion or diabetic macular edema, and uveitis, among others. But IVIs are not without their risk of complications and the most feared of which is infectious endophthalmitis, which can occur following intravitreal injections and has potentially devastating visual consequences, including loss of vision and/or the eye itself. Although endophthalmitis´s incidence ranges from 0-0.2% per infection, the cumulative risk for patients under sequential treatment may equate to more than 1% after 2 years of treatment. Endophthalmitis management following IVIs generally consists of a vitreous tap and inject (TAI) and/or a pars plana vitrectomy (PPV) with intravitreal injection of antibiotics. However, there is no consensus on the optimal treatment of IVI-related endophthalmitis. Thus, an established treatment protocol for IVI-related endophthalmitis is warranted to optimize patient outcomes. The aim of this study is to determine whether PPV or TAI is superior for the treatment of IVI-related endophthalmitis.
Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. It is thought that the retina slips inferiorly due to the residual subretinal fluid shifting as the patient transitions from the supine position intraoperatively to the sitting up position in the immediate postoperative period. By having the patient immediate position facedown or according to the retinal break, the risk of slippage is theoretically decreased.
This study will evaluate the efficacy and safety of ocrelizumab ( Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study focuses on upper limit disability progression. This study will consist of the following phases: screening, double-blind treatment, follow-up 1 (FU1), an optional open-label extension (OLE), follow-up 2 (FU2), and B-cell monitoring (BCM).
Introduction: Clinical practice guidelines recommend shared decision making (SDM) to facilitate goals-of-care discussions. This study will train clinicians about how to use a context-adapted decision aid (DA) and SDM to conduct goals-of-care discussions with the elderly. The objectives of this study are to: 1) determine if the use of the DA and SDM training program: a) increase clinicians' engagement of patients in decision making regarding their goals of care; b) increase adoption of evidence-based behaviours regarding goals-of-care decision making; and 2) identify patients' most frequent incomprehension, concerns, questions and clinicians' opportunities to improve the skills in goals-of-care decision making. Methods: This study will have three phases. Phase I (May-June 2017) will be a baseline evaluation of the current goals-of-care decision making process with elderly patients in a single ICU setting (Levis, Quebec). Phase II (July-August 2017) will be an evaluation of the goals-of-care decision making process in the same ICU using a DA. Phase III (September-December 2017) will be the delivery of an online and in-person training session about the use of the DA and about how to conduct discussions about goals-of-care. The study will then evaluate the goals-of-care decision making process after completion of the training program and using the DA. The investigators will observe and audio- or video-record all eligible elderly-intensivist dyads discussing goals of care during each phase. Two investigators will analyse the recordings using the OPTION 12 scale (measuring the extent that clinicians engage patients in SDM) and the ACCEPT quality indicators (measuring the extent to which intensivists engage in best practice goals-of-care discussions). The investigators will conduct qualitative content analysis of the video and audio records to identify patients' most frequent incomprehension, concerns, questions and clinicians' opportunities to improve the goals-of-care decision-making skills. Deliverables: This study will produce evidence regarding the impact of a context-adapted DA and training program on clinicians' adoption of SDM and other best practice behaviors regarding goals-of-care decision making with the elderly, and evidence regarding the most frequent patients' incomprehension, concerns, questions and clinicians' opportunities to improve the goals-of-care decision-making skills.
This study will assess the safety and tolerability of a new liquid anti-adhesion device, Discrete(TM), in healthy volunteers, in order to determine the best volume of Discrete(TM) to go forward into clinical efficacy research. The clinical trial will progress in accordance with first-in-human study guidance from the United States Food and Drug Administration (US FDA) and European Medicines Agency (EMA). It will be conducted as a randomized, controlled, double-blinded, single ascending volume, single-center, interventional safety trial. Participants will remain blinded to treatment until end of clinical trial. A maximum of 7 cohorts will be studied to assess maximum tolerated volume of investigational medical device compared with Control Lactated Ringer's solution (LRS) administered intraperitoneally. The trial will commence with a low volume and progress in a sequential, stepwise volume-escalating schema until defined maximum tolerated volume criteria are met. Following determination of the maximum tolerated volume, it is anticipated that up to 2 additional cohorts will be enrolled, wherein all participants will also receive a single standard dose of a commonly used anticoagulant as used in surgeries. A maximum of 81 participants will be enrolled. Eligible and consented adult men and women will be sequentially enrolled within each cohort at a ratio of 6 participants on Discrete(TM) to 3 participants on Control LRS. Participants will be followed for up to 10 days after intraperitoneal application. An independent Data and Safety Monitoring Committee will closely review safety in the clinical trial.
Peritoneal dialysis (PD) is actively promoted as the preferred form of dialysis for patients with kidney failure. However, 1 in 5 patients will experience a signification catheter insertion-related PD catheter complication in the first 6 months following insertion. Little is known about the patient-, operator-, and center-level factors that influence PD catheter complications. There is a need to identify key modifiable practices to focus randomized trials and quality improvement efforts. We will leverage prior funding, a custom-built data collection platform, pilot data, and a group of engaged stakeholders, partners, and knowledge users to: a) Determine if method of insertion is associated with PD catheter complications b) Identify operator/center characteristics and practices associated with PD catheter complications c) Use a data-driven approach to achieve expert consensus on optimal practices for PD catheter insertion and care.
More than 10% of Canadians have gallstones, and approximately 10% of these individuals will develop gallbladder inflammation related to gallstones, which is referred to as acute cholecystitis (AC). Patients with AC who do not have their gallbladder surgically removed have a 30% risk of serious complications that can lead to death. Surgery is the only definitive treatment for AC, however, there is controversy regarding the ideal timing of surgery. The two main approaches are early surgery (typically within 7 days of diagnosis) or delayed surgery (7 days to 6 weeks after diagnosis). Although preliminary evidence suggests that early surgery is associated with shorter hospital length of stay, lower risk for complications, and lower costs, practice varies widely regarding the timing of surgery. The limitations of the existing studies include small sample sizes, varied definitions of early versus delayed surgery, and an imbalance of risk between study groups. The proposed pilot study aims to inform the design of a large clinical trial that will compare the outcomes of patients with AC who receive accelerated surgery (i.e., as soon as possible with a goal of surgery within 6 hours of diagnosis) with those who receive standard care.
This study seeks to explore the effects of transcranial direct current stimulation (tDCS), a non-invasive method of brain stimulation, as an adjunctive treatment to improve antipsychotic medication adherence in patients with schizophrenia (SCZ). The investigators hypothesize that 20 sessions of tDCS will improve medication nonadherence in patients with SCZ.
