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 purpose of the study is to collect valuable data on the role of controlled humidity, temperature, airflow, and visual tasking in altering the tear film protein composition. The results from this preliminary study will help to explore the role of tear film markers in inflammatory and disease conditions. This can also be extended to understand the role of the tear film in protecting the ocular surface when individuals are exposed to low humidity environments which may incite discomfort symptoms.
The purpose of this open-label, multicenter, randomized, Phase III study is to evaluate the benefit of venetoclax in combination with rituximab compared with bendamustine in combination with rituximab in participants with relapsed or refractory CLL. Participants will be randomly assigned in 1:1 ratio to receive either venetoclax + rituximab (Arm A) or bendamustine + rituximab (Arm B).
The purpose of this clinical study is to evaluate the safety and efficacy of the Micra Transcatheter Pacing System and to assess long term performance.
Sunnybrook Health Sciences Centre is Canada's largest trauma centre, treating 1,100 patients annually. A traumatic experience can lead to post-traumatic stress disorder, which increases hospital stays, emergency visits and disability. Despite developing leadership to manage a "Code Orange" mass trauma, Sunnybrook lacks guidelines in the psychological management of patients who have experienced trauma. The department of psychiatry currently holds a Traumatic Brain Injury clinic and PTSD services for youth but lacks both immediate intervention, prevention and adult services. This research will enable us to gain best evidence expertise to develop guidelines as well as a sustainable PTSD treatment program, with clear outcomes to assess effectiveness, psychiatric morbidity, use of healthcare, disability and substance abuse. The five world-expert-consensus intervention resilience based principles will be operationalized in guidelines for the management of trauma patients, their caregivers and in routine nursing and trauma team care from the Emergency to the ward, and discharge, through to outpatient care. It is hypothesized that this will improve the psychological recovery of patients at risk of developing PTSD after a traumatic injury. In addition, early screening and intervention for increased risk of PTSD will be implemented one month after the trauma. It is hypothesized that such trauma informed psychological management, early screening and expert treatment using prolonged exposure will reduce hospital stays, functional disability, as well as longer-term psychiatric morbidity, including substance abuse.
Patients with localized prostate cancer are routinely treated with radiation therapy to the entire prostate gland. The investigators can identify where the cancer is concentrated in the prostate gland using a newer specialized imaging technique called 11C Choline PET (stands for choline positron emission tomography). This is different from the older type of PET scan that has been used in the past (called FDG PET) which has not been as accurate as the new PET scan for identifying where the cancer is in the prostate gland. It has also been shown that delivering higher doses of radiation to prostate cancer cells in the prostate have resulted in better cure rates in patients with prostate cancer. Therefore for goal number one the investigators want to give higher radiation dose to the prostate cancer cells. But the challenge has been that delivering higher doses of radiation to the prostate gland may also increase the chance of complications from the higher doses of radiation to the rectum, bladder and surrounding area. Therefore for goal number two the investigators want to minimize radiation dose to the rectum, bladder and surrounding area. 3-Tesla Magnetic Resonance Imaging (3T MRI) is a new kink of scan that will be used in this study to identify the urethra in the prostate so that the investigators can minimize the radiation dose to the urethra. The investigators believe the 3T MRI scan is able to point to the areas of cancer that may be able to predict how well the treatments may work, as well as which areas of the tumor appear to be responding to failing. In this study, the investigators will keep the dose of radiation to the rectum and bladder as low as possible while increasing radiation dose to parts of the prostate with more cancer cells. The investigators will compare the cure rates in this study with the cure rates of other patients receiving the standard treatment in which the same dose of radiation is delivered throughout the prostate gland. The investigators will also compare the rates of complications in this study with the rates of complications in patients receiving the standard treatment in which the same dose of radiation is delivered throughout the prostate gland.
This study will evaluate the effect of chloroquine in individuals infected with HIV. Researchers will aim to determine if chloroquine treatment in participants whose viral loads are suppressed on combination antiretroviral therapy (ART), results in improved immune activation and CD4 cell recovery. The study will recruit 20 individuals and will last approximately 44 weeks. Eligible participants will receive an oral dose of chloroquine (250 mg) once daily from week 8 through week 32. All participants will be asked to have rectal biopsy samples (week 0 and week 32) to study T cell immune activation in the mucosa rectal site.
Test the safety, immune response and efficacy of GVAX pancreas vaccine (with cyclophosphamide) and CRS-207 compared to chemotherapy or CRS-207 alone in adults with previously treated metastatic pancreatic adenocarcinoma
This study will evaluate the efficacy and safety of pertuzumab in combination with carboplatin-based standard chemotherapy in patients with platinum-sensitive recurrent ovarian cancer. The anticipated time on study treatment is 3-12 months.
The purpose of this study is to determine whether eculizumab long-term use is safe and effective in patients with relapsing NMO.
Individuals with Cystic Fibrosis (CF) have a defective protein, which is known as the cystic-fibrosis transmembrane regulator (CFTR). The CFTR transports salt and hydrates mucous. CFTR defects may result in the accumulation of thick mucous in the sinus cavities. As a result, the tiny hair-like structures that sweep mucous out of the sinuses cannot function properly, which can lead to recurrent infection and swelling of the sinus walls. When symptoms are persistent for more than 12 weeks, this is known as chronic rhinosinusitis (CRS). The symptoms that are associated with CRS are nasal discharge, congestion, facial pain or pressure and reduced sense of smell. CRS in non-CF patients affects a large number of individuals in Canada and has been found to be associated with poor quality of life. In the CF population the life expectancy is increasing but chronic disease like CRS is becoming increasingly prevalent. Investigators currently do not know the impact that CRS has on the health-related quality of life in adults with CF and how many suffer from symptoms. The investigators aim to determine the impact of CRS among adults with CF, in order to gain a better understanding of chronic disease among these individuals. The investigators strongly feel this research will improve the referral processes between Respirologists and Otolaryngologists, thereby improving treatment and quality of life for patients.
