All Clinical Trials in Canada

Somatostatin receptor (SSR) imaging is a critical component of clinical care for many patients being investigated for or with confirmed SSR positive tumors. In the past, 111In-octreotide imaging has been used for this purpose but it has been recently supplanted globally by SSR positron emission tomography (PET) imaging due to better image quality and higher diagnostic accuracy. This study will assess the safety and diagnostic effectiveness of 68Ga-HA-DOTATATE produced a the Edmonton Radiopharmaceutical Centre (ERC). Read Less

Remote physiologic monitoring (RPM) of heart failure (HF) patients with a virtual platform is well established in adult care. However, this technology remains untested in pediatrics and care continues to rely on a hospital-based model which presents challenges in providing equitable access to care for those with lower socio-economic status or living remotely. Telemonitoring technology tailored for children with machine-based algorithms to predict deterioration is needed to facilitate the equitable provision of safe, home-based care, especially in vulnerable populations. This study will enroll 100 pediatric outpatients with or at risk of deteriorating HF from 4 tertiary pediatric heart failure care centres in Canada. We will use a wearable Bluetooth enabled textile (Skiin device), developed by Myant Inc (Toronto, ON), that can monitor heart rate, heart rhythm, respiratory rate and activity, together with additional home-based monitoring of blood pressure (BP), oxygen saturations and weight. The smart textile will be paired to an RPM platform, SphygmoTM (mmHG Inc). The goal of this project is to assess the feasibility and acceptability of RPM in pediatrics and validate a RPM-based risk prediction model for pediatric HF patients. Read Less

The goal of this 14-day randomized pilot trial is to assess the accuracy of a continuous ketone monitoring (CKM) system when compared to standard point-of-care capillary ketone monitors in individuals with type 1 diabetes on insulin pump therapy. The main question it aims to answer is: - Can a CKM system demonstrate equivalent ketone monitoring compared to a capillary ketone monitor with accuracy within a mean absolute difference of no more than ± 0.1 mmol/L. Participants will be asked to wear the SiBio KS1 CKM system for 14-days while undergoing two sequential ketogenic diets which are interspaced by an inpatient insulin-suspension period. Read Less

Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant. Regular treatment for patients with aplastic anemia who have a matched sibling (brother or sister), or family donor is a bone marrow transplant. Patients without a matched family donor normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone marrow transplant (BMT) is used as a secondary treatment in patients who did not get better with IST, had their disease come back, or a new worse disease replaced it (like leukemia). This trial will compare time from randomization to failure of treatment or death from any cause of IST versus URD BMT when used as initial therapy to treat SAA. The trial will also assess whether health-related quality of life and early markers of fertility differ between those randomized to URD BMT or IST, as well as assess the presence of marrow failure-related genes and presence of gene mutations associated with MDS or leukemia and the change in gene signatures after treatment in both study arms. This study treatment does not include any investigational drugs. The medicines and procedures in this study are standard for treatment of SAA. Read Less

Knee replacement surgery is the second most common surgery in Canada. People who have very painful knee arthritis usually receive a knee replacement where the surgeon aims to make everyone's knee as straight as possible (called mechanical alignment). Mechanical alignment focuses on making the implant last as long as possible. However, everybody's knee shape is different and we think that it is important to take individual differences into account. A newer technique that is more personalized is called restricted kinematic alignment. This technique customizes the placement of the new knee to reproduce each patient's unique knee shape, which may not be perfectly straight. We think this newer technique may feel more natural, be more stable, and lead to better knee function. Restricted kinematic alignment might last as long or longer than mechanical alignment, but the research that has been conducted to date is not clear. We are conducting this study to help surgeons better understand which technique is better. One of the reasons the existing research is not clear is because new developments in robotic technology now allow surgeons to place knee implants very precisely, which was not done in most previous research. In this study everyone will receive a robot-assisted knee surgery so we can be sure the implants are placed as precisely as possible. The purpose of this trial is to determine whether there are differences in patient outcomes using restricted kinematic alignment rather than the traditionally used mechanical alignment for total knee replacements. Participants who are having total knee replacements will be randomized to receive either a robot-assisted total knee replacement using mechanical alignment, or a robot-assisted total knee replacement using restricted kinematic alignment . We will ask participants to walk in a markerless motion capture system which will measure walking characteristics at pre-op, 6 months postop and 12 months postop. Participants will also complete a series of standardized questionnaires at preop and 6 months, 12 months, and 24 month postop. Read Less

This study will evaluate the safety of tisagenlecleucel that is out of specification( OOS) for release as commercial product. Specifically, this study will evaluate the safety of CTL019 in the patients treated within the approved label by Japan Health Authority in Part 2. Only for Part 1, in addition to safety, key efficacy of CTL019 will also be evaluated. Read Less

Pompe disease is a genetic condition which causes muscle weakness over time. People with Pompe disease have a faulty gene that makes an enzyme called acid alpha-glucosidase (or GAA). This enzyme breaks down a type of sugar called glycogen. Without this enzyme, there is a build-up of glycogen in the cells of the body. This causes muscle weakness and other symptoms. Pompe disease can happen at any age, but in late-onset Pompe disease, symptoms generally start from 12 months old onwards. The standard treatment for people with Pompe disease is to receive regular infusions of the GAA enzyme. This is known as enzyme replacement therapy. However, people can build up antibodies against the GAA enzyme over time. Gene therapy is used to treat conditions caused by a faulty gene. It works by replacing the faulty gene with a working gene inside the cells of the body. The working gene is delivered into the cells using certain viruses as carriers (vectors). Viruses are often used as carriers as they can easily get inside cells. The genetic material of the original virus is replaced with the working gene, so only the working gene gets inside the cells. A common virus used as a carrier in gene therapy is the adeno-associated virus (or AAV). This is like an adenovirus, which causes the common cold. The original type of AAV does not cause any harm to humans. However, people that have previously been infected with the original type of AAV may have built up antibodies against AAV. These antibodies may stop the AAV carrier with the working gene getting inside the cells. Researchers want to learn more about antibody levels against AAV and the GAA enzyme in people with late-onset Pompe disease. They also want to learn about other substances in the blood that provide more information about late-onset Pompe disease. These are known as biomarkers. In this study, older teenagers and adults with late-onset Pompe disease will take part. They will not have had gene therapy using AAV. There will be 2 groups - those who have never had enzyme replacement therapy, and those who have had enzyme replacement therapy for 6 months or more. No study treatment will be given during the study, but blood and urine samples will be taken for testing. The main aims of the study are to check antibody levels against AAV8 (a type of AAV) in people with late-onset Pompe disease who had not received any treatment using AAV, to check antibody levels against the GAA enzyme in people previously treated with GAA as part of enzyme replacement therapy, to check levels of biomarkers for Pompe disease, and to check for medical problems. In the study, people will visit the study clinic several times. Some visits may be in the person's home. The first visit is to check if they can take part. Those who can take part will have a medical examination, and have their vital signs checked. Vital signs include blood pressure, heart rate, breathing rate and temperature. Blood samples will be taken to check antibody levels against the GAA enzyme and against AAV8. Blood and urine samples will also be taken to check for biomarkers for Pompe disease. Blood and urine samples will be taken about every 4 months for up to 2 years. Read Less

Temporal lobe epilepsy (TLE) is a common type of epilepsy and one of the most likely to not be controlled by medication. For patients who do not respond to medication, surgery can result in a cure of seizures. Given the fact that around 50% of patients who undergo surgery are seizure free at 10 years there is a need to improve the understanding of what factors best predict surgical outcomes in order to improve our ability to select candidates for surgery. The demonstration of abnormalities in the temporal lobe on MRI is one of the best predictors of seizure free surgical outcomes. Recent studies suggest that changes in specific subregions of the hippocampus could be the strongest predictors of surgical success, however the small size of these regions, (millimeters) make them very difficult to study with standard clinical MRI. Recently new MRI methods have been developed at Wayne State University to image hippocampal blood vessels using ferumoxytol infusion. Feraheme (ferumoxytol) is a drug that is approved in the United States for the treatment of iron deficiency anemia and is currently being studied as an MRI contrast agent in 8 active clinical trials in the United States as well as a Parkinson's Disease study in Canada.

Following a stroke, persistent residual muscle weakness in the upper limb (UL) drastically impacts the individuals' quality of life and level of independence. Training interventions are recommended to promote UL motor recovery, and recent studies have shown that training must be tailored to each individual's recovery potential to maximise training gains. Complementary to training interventions, non-invasive brain stimulation devices (NIBS) can help support the provision of post-stroke care by modulating brain excitability and enhancing recovery. Among NIBS, cranial nerve non-invasive neuromodulation (CN-NINM) is gaining increasing attention in rehabilitation since it can directly and non-invasively stimulate the tongue's cranial nerves. The impulses generated can then reach the motor cortex, induce neuroplastic changes and support recovery. Promising results in various neurological populations have been observed, but in stroke, the efficacy of CN-NINM at improving arm motor recovery and brain plasticity is yet to be determined. This is what the present project intends to address, using a stratified randomized controlled trial, where participants in the chronic phase of a stroke will take part in a 4-week individualized training program of their affected UL in combination with real or sham CN-NINM. Before and after the intervention, participants will undergo clinical and neurophysiological evaluations to thoroughly evaluate CN-NINM-induced changes in UL motor function and associated neuroplastic changes. The proposed study will allow an in-depth evaluation of the effects of CN-NINM for an eventual implementation in clinics and at home to support optimal post-stroke recovery. Read Less
