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.
There are large inter-individual differences in the bleeding pattern of patients with moderate or mild hemophilia. The major determinant of bleeding phenotype is the level of coagulant factor VIII or IX. In hemophilia A, studies addressing the association between factor VIII level and the clinical bleeding pattern yield conflicting results. In hemophilia B such studies have not yet been performed. The primary aim of this project is to analyze the association between factor VIII and factor IX levels and the bleeding phenotype. The secondary aim is to analyze potential differences in phenotype between hemophilia A and B. The project is a multicentre observational cohort study. We will include 500 patients with moderate or mild hemophilia A (FVIII 0.02-0.35 IU/mL) and 500 patients with moderate or mild hemophilia B (FIX 0.02-0.35 IU/mL) who are 12 to 55 years old. The main cohort study consists of clinical data collection, one blood sample and an online questionnaire for patients. Data will be collected on the nature and duration of all bleeding episodes, disease and treatment characteristics, physical activity level and musculoskeletal status. One blood withdrawal will be performed for centralized laboratory assays for FVIII or FIX levels (both one-stage and chromogenic assays) and genetic analysis for the most prevalent prothrombotic mutations. The online questionnaire for patients focuses on bleeds experienced in the past. A subset of 200 patients aged 24 years or older (100 with moderate or mild hemophilia A and 100 with moderate or mild hemophilia B) will be investigated in more detail by longitudinal data collection including analysis of physical joint status, MRI imaging of joints and biomarkers for joint damage. This longitudinal observation will consist of two time points that lie two years apart, allowing us to identify any changes that occur over the observed time period with respect to joint status.
Randomized, controlled, multisite, subject-and observer-masked, 3-arm parallel group clinical trial of 36-month duration to evaluate the safety and efficacy of a novel spectacle lens design in reducing the progression of juvenile myopia.
The primary efficacy objective of this study is to test the hypothesis that DBS-f stimulation (ON) will slow cognitive and functional progression of AD, as compared to no stimulation (OFF), by measuring baseline (pre-implantation) to 12-month change in the integrated Alzheimer's disease rating scale (iADRS).
The goal of this project, is to better understand the fluctuation of the level of uric acid in traumatized patients by making serial measurements during their hospitalization in the intensive care unit. In addition, the determinants (e.g. type of trauma, diseases, interventions) of the blood level of uric acid and its association with the development of organ failure will be sought.
This study will evaluate the efficacy, safety, and pharmacokinetics of faricimab administered at 8-week intervals or as specified in the protocol following treatment initiation, compared with aflibercept once every 8 weeks (Q8W), in participants with diabetic macular edema (DME).
This study will examine how Brain Power Score, an objective measure of brain function, is affected by the presence of smartphone push notifications.
Patients with head and neck cancer typically undergo a surgical procedure to remove the lymph nodes that could contain disease on both sides of the neck. After surgery, radiotherapy is given (with or without chemotherapy) to the area that underwent surgery and both sides of the neck, even if disease was only found on one side. Giving radiotherapy to both sides of the neck commonly results in high rates of side effects, which in turn affects patient quality of life. There is growing evidence from some other studies that support the safety of omitting radiotherapy after surgery in the side of the neck with no disease. With this study, the investigators are hoping to justify its routine use and, if successful, the standard of care could be to receive radiation on only one side of the neck instead of both sides. This could alleviate the extent of some side effects and improve patient quality of life. Participants will be randomized into one of the following groups to receive radiotherapy as follows: Arm 1 (Non-experimental intervention): standard intervention: Radiotherapy to both sides of the neck. Treatment will begin a maximum of 8 weeks from the surgery date. Arm 2 (Experimental intervention): Radiotherapy to one side of the neck. Treatment will begin a maximum of 8 weeks from the surgery date.
3 clinical sites enrolling in the primary MINVI trial (NCT# ) will collect Near Infrared Spectroscopy (NIRS) data in the first 10 minutes of life on a subset of 200 non-vigorous term and near-term infants enrolled in the trial.
An extension of the MINVI trial, the MINVI Follow-Up trial will evaluate the neurodevelopmental outcomes at 22-26 months corrected age of term/near term infants who received UCM or ECC.
Diagnosis of melanoma involves physical examination of the lesion with many dermatologists adjunctively employing dermoscopes. The rate of misdiagnosis of melanoma remains significant, along with a high rate of referral to biopsy. Elucid Labs (Waterloo, Ontario) has developed a novel handheld, digital dermoscope with accompanying visualization and analysis software - the Artificial Intelligence Dermatology Assistant (AIDA™). Apart from collecting conventional demoscopic images, AIDA also collects images at various spectral bands. The aim of this study is to understand and quantify the value of this novel adjunctive information for dermatologists diagnosing atypical skin lesions.
