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.
This study proposes to compare current multimodal analgesic treatment for TKA with a new multimodal analgesic regimen to demonstrate decreased opioid requirement, time to rehabilitation, and time to reach hospital discharge.
Placebo Controlled, double-blind randomized controlled trial (RCT) with 12 months Tenofovir Disoproxil and Raltegravir for primary biliary cholangitis (PBC) patients unresponsive to Ursodeoxycholic Acid (UDCA). Placebo patients will be offered 12 months open label therapy at unblinding. All patients will be offered an additional 12 months open label therapy. Observational, open label study will be performed in parallel using Emtricitabine (FTC)/Tenofovir Disoproxil (TDF) & Raltegravir in liver transplant recipients meeting all entry criteria except for use of immunosuppression.
The aim is to conduct a double-dummy multi-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TxA) versus the usual intravenous TxA in patients undergoing on-pump cardiac surgery.
Opioids (morphine and morphine-like substances) are often prescribed to patients to manage pain after an emergency department visit. In the past 20 years, opioid prescriptions have risen sharply, accompanied by a significant rise in opioid misuse (e.g., recreational or non-medical use, potentially leading to addiction or overdose). One explanation for this crisis is the availability and easy access of leftover opioid pills in Canadian homes, allowing family members (including children) and friends to take them for reasons other than pain relief. Canada has no recommendations for the dosage, duration, or quantity of opioids that physicians should prescribe to manage acute pain at home. Physicians are therefore left guessing as to how much to prescribe when a patient with a condition like a fracture or renal colic is discharged from the emergency department. Our preliminary study showed that two-thirds of the pills from the initial opioid prescription to treat acute pain actually remained unused and were therefore available for potential misuse. The investigators propose to determine how many opioid pills are consumed by patients who suffer from acute pain as they recover at home. The investigators will ask 2,560 patients (from 6 Canadian hospitals) to record their pain medication consumption in a 14-day diary. The investigators will also determine, their pain intensity level, whether or not they had new opioid prescriptions, and health services revisits. In case of missing information, patients will be contacted by phone at 2 weeks. The overall aim is to help emergency department physicians prescribe the right number of pills in order to manage patients' pain and at the same time reduce substantially leftovers available for potential misuse.
The purpose of the study is to evaluate effect of benralizumab on structural and lung function changes in severe eosinophilic asthmatics. Changes will be assessed over 48 week treatment period in patients with persistent symptoms despite standard therapy of inhaled corticosteroids (ICS) plus long acting B2-agonist (LABA) with or without additional controller medication. Patients who complete treatment will enter 4 weeks follow-up period.
With the advent of CT screening for lung cancer, an increasing number of NSCLCs are being detected at very early stages, and the demand for pulmonary segmentectomy is rising rapidly. As such, there is a need to develop new surgical techniques to facilitate minimally invasive pulmonary segmentectomy, as segmentectomy may provide a number of significant advantages over lobectomy for patients presenting with early-stage lung cancer, or for patients unable to undergo a full lobectomy due to existing comorbidities. This study will provide the first case series using preoperative 3D anatomical planning (Synapse 3D) added to ICG and NIF-guided robotic segmentectomy to date and will be the first reported use of Synapse 3D-guided targeted pulmonary segmental resection in Canada. As lung cancer is the most frequently fatal cancer in North America, many thousands of patients will be able to benefit from this operation every year.
The purpose of this study is to identify pharmacogenetic profiles associated with selective serotonin reuptake inhibitors (SSRI)-induced behavioral disinhibition in children with Major depressive disorder (MDD), anxiety disorders and/or obsessive-compulsive disorder (OCD) that could be used clinically to reduce the incidence of this adverse event and improve health outcomes.
Rhinitis is inflammation of the inside of the nose. Symptoms of rhinitis include itchiness, sneezing, and a "runny" nose (rhinorrhea). There are many different causes for rhinitis, including allergies, age, different irritants in the air, overacting nervous system, and others. Many current treatments for rhinitis are not helpful or are unable to be used for long periods of time. Capsaicin ("Kap-Sey-Uh-Sin") is a natural product that is found in many spicy foods, including hot peppers. This natural product has been used as a lotion to prevent pain, and scientists have found that it may reduce the symptoms of rhinitis when used as a spray in the nose. However, capsaicin is known to cause a burning sensation. This study is needed so we can figure out what doses of capsaicin cause this burning sensation, and to what level these doses cause discomfort. Capsaicin can also cause a small degree of tearing from the eyes when used as a spray in the nose, and can also cause the nose to become "runny" (rhinorrhea). When the safest dose of capsaicin spray is found, that dose can be used to treat people with rhinitis that is not getting better from standard treatments.
This phase II/III trial studies how well a reduced dose of radiation therapy works with nivolumab compared to cisplatin in treating patients with human papillomavirus (HPV)-positive oropharyngeal cancer that is early in its growth and may not have spread to other parts of the body (early-stage), and is not associated with smoking. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial is being done to see if a reduced dose of radiation therapy and nivolumab works as well as standard dose radiation therapy and cisplatin in treating patients with oropharyngeal cancer.
The British Columbia (BC) Farmers' Market Nutrition Coupon Program (FMNCP) provides low-income households with $21/week in coupons to purchase healthy foods at farmers' markets and supportive nutrition skill-building activities. This randomized controlled trial will assess the impact of the BC FMNCP on the overall diet quality (primary outcome), diet quality subscores, mental well-being, sense of community, experiences of food insecurity, risk of malnutrition (secondary outcomes) and subjective social status (exploratory outcome) of low-income adults immediately post-intervention and 16 weeks post-intervention.
