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 Boston keratoprosthesis (KPro) is a special plastic device that is used to replace a sick cornea (transparent part of the eye, in front of the iris) in order to restore vision in patients who have failed traditional corneal transplants or have a very poor prognosis of success. Glaucoma is a chronic disease which causes optic nerve damage secondary to high pressure inside the eye and could lead to vision loss in the long term. Glaucoma is highly prevalent in patients who require a KPro and even more after their procedure. In order to decrease the intra-ocular pressure, surgeons can use multiple eyedrops. Unfortunately, following the KPro surgery, eyedrops lose their efficiency because they are less absorbed by the eye. The transscleral cyclophotocoagulation (TS-CPC) is a laser treatment used in advanced refractory glaucoma. This laser helps decrease the intra-ocular pressure and have a better control of the disease. There are different methods of laser transmission, including the continuous transmission (G-Probe) and the micro-pulsation method (Micopulse). Given the high prevalence of glaucoma in patients receiving a KPro, the investigators are studying the effect of giving the TS-CPC treatment prophylactically to patients before their Boston keratoprosthesis. Our hypothesis is that prophylactic TS-CPC will decrease glaucoma progression as well as the risks of developing glaucoma following the Boston keratoprosthesis . METHOD The investigators aim to recruit twenty (20) patients who are scheduled to receive Boston KPro. Participants will be randomized into two groups: 1) Groupe 1 will receive a prophylactic treatment of transscleral cyclophotocoagulation a G-Probe. 2) Groupe 2 will receive a prophylactic treatment of transscleral cyclophotocoagulation with a micropulse transmission (MicroPulse). The patients will receive their laser treatment by a glaucoma specialist 4 to 8 weeks before their KPro surgery. One week following their laser treatment, the participants will be examined by their glaucoma specialist. Following their KPro surgery, patients will have a follow-up at day-1, weeks 1 and 2, months 1 and 3, then every 4 to 6 months for 5 years. Additional non-invasive glaucoma tests will be performed twice during the first 3 months following the surgery and will be repeated every 4-6 months. Visual acuity results, the visual field tests and rates of post-operative complications will be compared between the different groups.
The objective of the current project is to pilot the evaluation of the health and economic benefits of having online access to health information in the context of providing telemedicine support for oncology patients receiving outpatient systemic therapy in Ontario. This pilot study will determine the feasibility of conducting a full-scale randomized controlled trial that could definitively determine whether the addition of access to patients' health information in the after-hours telemedicine program reduces emergency department use, affect patients' experience of care, or improve patient-reported health. The study will be conducted at, and with patients from, the Stronach Regional Cancer Centre (SRCC) at Southlake. Eligible patients will be adults (at least 18 years of age) with a confirmed cancer diagnosis, and initiating or continuing treatment with systemic therapy at the SRCC. Prospective patients will be randomized across two arms. Recruitment will take place during a 6.5-month recruitment period and followed up for a period of 3 months.
This is a pilot randomized, double-blind, active-controlled, 2-treatment, crossover study to evaluate the PK, user experience and abuse liability of manipulated ADAIR compared to a manipulated commercially-available d-amphetamine sulfate IR formulation administered intranasally in non-dependent recreational stimulant users. The study is comprised of 4 phases: Screening, Qualification, Treatment, and Follow-up/Early Termination.
The reason for this study is to determine the long-term efficacy and safety of the study drug mirikizumab in participants with Crohn's disease.
This study will examine the feasibility and effect of a program that combines exercise and feedback from a wearable device on upper limb movement practice and function in individuals with stroke.
During exercise in conditions of low oxygen (termed hypoxia), such as mountaineering at high altitudes, the lung blood vessels constrict in an attempt to protect the body from the negative effects of hypoxia. It appears that this blood vessel constriction may limit the heart to pump blood during heavy exercise, leading to reductions in exercise performance. Inhaled nitric oxide is a drug that is known to relax the lung blood vessels. Inhaled nitric oxide has been used to relax lung blood vessels and improve exercise capacity in patients with chronic disease. It is unknown if similar improvements would be observed during exercise in healthy individuals when exposed to low levels of oxygen. The goal of this study is to determine if inhaled nitric oxide can relax the lung blood vessels and improve the heart's pumping ability during exercise in low oxygen conditions. Further, the investigators will determine if these improvements in lung blood vessel and heart function increase exercise performance. Participants will complete 6 sessions over a three week period where they will perform exercise challenges while breathing low levels of oxygen with and without inhaled nitric oxide. The low oxygen conditions will be comparable to being at an altitude of 14,000-17,000 feet. 17,000 feet would be equivalent to standing on the summit of King Peak in the Yukon (the 4th tallest mountain in Canada).
This is a Phase 1, first-in-human, open-label, multicenter study of CC-97540, CD19-targeted NEX-T chimeric antigen receptor (CAR) T cells, in subjects with relapsed or refractory B-cell non-Hodgkin lymphoma. The study will consist of 2 parts: dose-escalation (Part A) and dose-expansion (Part B). The dose-escalation part (Part A) of the study is to evaluate the safety and tolerability of increasing dose levels of CC-97540 to establish a recommended Phase 2 dose (RP2D); and the dose-expansion part (Part B) of the study is to further evaluate the safety, pharmacokinetics/pharmacodynamics, and efficacy of CC-97540 at the RP2D.
Posttraumatic stress disorder (PTSD) is a common and disabling condition associated with intimate relationship problems and mental health problems in partners of those with PTSD. Recognizing the need to improve access to evidence-based interventions for those with PTSD and their families, our team has developed an Internet-delivered, self-help intervention to improve PTSD, enhance relationships, and improve partners' mental health: Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction). Couple HOPES presents text and video-based content across seven self-help intervention modules, with modest support from paraprofessional coaches. Although the Couple HOPES platform has been developed, it remains uncertain whether Couple HOPES is feasible, usable, and efficacious in reducing PTSD and enhancing intimate relationship functioning. The proposed project aims to refine and finalize Couple HOPES with couples that include a veteran, service member or first responder with significant PTSD symptoms. This project includes initial testing of the intervention's preliminary efficacy, safety, and feasibility in a series of 10 couples (Phase 1), then in an uncontrolled trial of 20 couples (Phase 2), and then a randomized clinical trial comparing its efficacy to a delayed intervention control condition in 70 couples. Potential benefits of this study include couples learning new skills to reduce PTSD symptoms and enhance relationship functioning, although this is not guaranteed. Risks include participants finding the assessments distressing, or possible worsening of PTSD symptoms or relationship functioning. These risks will be mitigated by continuous monitoring of PTSD symptoms, relationship functioning, and adverse events, and intervention by study staff.
This is a pilot study of combination therapy using FMT and vedolizumab for induction of UC. The investigators hypothesize that a combination therapy approach which addresses immune trafficking and microbial manipulation simultaneously will lead to superior outcomes than those seen with single agent therapy.
The primary objective of this study is to determine if hypofractionated RT delivered over 1 week to the breast or chest wall and regional nodes (26Gy in 5 daily fractions) following BCS or mastectomy, is non-inferior to conventional fractionation to the breast or chest wall and regional nodes delivered over 3 weeks (40Gy in 15 daily fractions) in patients with node-positive breast cancer.
