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 is designed to determine the minimal effective oxytocin maintenance infusion required in labouring women undergoing cesarean delivery to achieve the best effect. Oxytocin is a drug that is routinely used to help the uterus to contract and keep it contracted after delivery. Consequently, it will help to reduce blood loss after delivery. In order to determine the minimal effective dose, the investigators will conduct a dose-finding study. The first patient will receive a set oxytocin infusion. The next patient's infusion dose of oxytocin, will either increase or decrease, depending on how the previous patient responds in terms of uterine tone. If the response is satisfactory with the infusion dose used, the next patient will either receive the same infusion dose or it will be decreased depending on a probability of 1:9. If the response is not satisfactory, then the infusion dose will increase for the next patient. The dose for each patient will be determined based on the results of the uterine contraction of the previous patient. The investigators hypothesize that the ED90 of the oxytocin infusion rate to maintain adequate uterine tone in labouring women with induced or augmented labour undergoing cesarean delivery, following an initial effective bolus dose, would be lower than 0.74 IU/min (44 IU/h), which was found as the ED90 in a previous study, without an initial bolus dose prior to the infusion.
Concussions are one of the most complex conditions to manage in sport medicine due to the individualized clinical presentation, caused by a complex neurometabolic cascade, and the lack of a diagnostic standard. There is currently no objective measurement for concussion and the reliance on subjective reporting and clinical judgement is imperfect. In previous clinical studies the investigators determined cutoff values of plasma phosphatidylcholines that provided strong indication that a concussion had occurred. Based on this data, the investigators have developed a custom assay, which will work together with a capillary blood collection device. The current clinical trial will be conducted in two parts. Part A will allow the investigators to determine precise AUC cut-off values for the propriety, novel custom assay, and in Part B the investigators will assess the safety and efficacy of this device for concussion diagnosis in adolescent athletes aged 13-17.
A multi-centre, non-blinded, comparative effectiveness, randomised controlled trial. Patients will be prospectively enrolled from Critical Care Units and will be assessed for study enrollment based on inclusion/exclusion criteria at the time of the onset of fast atrial fibrillation (AF)(irregular and often rapid heart rate). The authors hypothesize that high dose Magnesium Sulphate with the addition of Digoxin as a second line treatment will improve the success rate in returning the heart to normal rhythm as well as speed of resolution of critical illness in new onset rapid atrial fibrillation in the critically ill cared for in general ICUs.
The purpose of this study is to evaluate the safety and efficacy of the combination of retifanlimab plus INCAGN02385 and retifanlimab plus INCAGN02385 and INCAGN02390 compared with retifanlimab alone as first-line treatment in PD-L1-positive and systemic therapy-naive recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN).
Total Knee Arthroplasty (TKA) is also known as a knee replacement. It is one of the most common orthopaedic (bone) surgeries performed and is usually very successful, but some people who have had a knee replacement feel pain that lasts for at least 3 months after surgery and thus continue to take pain control/ analgesic (opioids) medication. Opiates are medications like morphine. Pain post-surgery can make it difficult to recover and return to daily activities. A better control of pain before the surgery, can help people feel less pain, recover faster, and use less opioids after surgery. Cryoneurolysis means freezing the nerves that can cause pain. It uses very low temperatures in a specific body part (e.g., nerves to the knee) to freeze the pain nerves and therefore reduce the pain. When applied before the surgery it might help with postoperative pain after knee replacement. This study will evaluate Iovera, a cryoneurolysis handheld device commercially available in Canada that delivers freezing cold to a target nerve by using nitrous oxide. Cryoneurolysis can relieve pain and symptoms associated with osteoarthritis of the knee for up to 90 days.
This phase I/II trial studies how well tiragolumab and atezolizumab works when given to children and adults with SMARCB1 or SMARCA4 deficient tumors that have either come back (relapsed) or do not respond to therapy (refractory). SMARCB1 or SMARCA4 deficiency means that tumor cells are missing the SMARCB1 and SMARCA4 genes, seen with some aggressive cancers that are typically hard to treat. Immunotherapy with monoclonal antibodies, such as tiragolumab and atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
MEKTOVI (binimetinib) is an oral, highly selective reversible inhibitor of mitogen-activated extracellular signal regulated kinase 1 (MEK1) and MEK2. The biological activity of binimetinib that has been evaluated bith in vitro and in vivo in a wide variety of tumor types In this Phase II, the drug will be used to treat pediatric patients diagnosed with recurrent Adamantinomatous Craniopharyngioma including patients who have undergone surgery and/or radiation therapy.
Background Some critically ill children have malnutrition which may worsen while they are in hospital and delay their return home. They can recover faster when they are given tube feedings to improve their nutrition. Unfortunately, in the hospital these feedings are often interrupted and so these children do not get all the nutrition they need. The usual procedure is to set hourly rates for the tube feedings and to accept that they get less when feedings are interrupted. The researchers would like to test if children are fed better if the bedside nurses were to check the volume provided through the day and then ensure the child gets closer to the prescribed volumes. Aim To determine the feasibility of performing a Randomized Control Trial assessing the use of a Volume-based feeding algorithm in critically ill children admitted to the Alberta Children's Hospital Pediatric Intensive Care Unit (PICU). Objectives 1. Obtain information to inform sample size calculations for nutrition and clinical outcomes for a larger RCT: energy adequacy and protein adequacy, feed tolerance, infections, changes in anthropometric measurements at transitions of care, 28-day ventilator free days, length of stay, 60-day mortality, and 60-day hospital readmission? 2. Assess adherence of medical staff to the study protocol 3. Evaluate the timing of study enrollment and participant allocation 4. Evaluate the proposed deferred consent strategy. Methods The researchers will conduct a randomized control feasibility trial of critically ill children admitted to the Alberta Children's Hospital (ACH) Pediatric Intensive Care unit who require tube feedings. Children will be randomly assigned to the intervention arm (Volume-based algorithm) or the comparison arm (rate-based algorithm). Significance The proposed study will provide evidence of whether a novel approach to feeding critically ill children is feasible during PICU admission. This trial will inform a larger Randomized Control Trial on this topic that will assess if using a Volume-based feeding algorithm will improve outcomes of clinical importance including energy adequacy, protein adequacy, feed tolerance, infections, changes in anthropometric measurements at transitions of care, 28-day ventilator free days, length of stay in PICU and hospital, 60-day mortality, and 60-day hospital readmission.
The purpose of this study is to determine the optimal radiation dose fractionation regimen for low grade follicular lymphoma. It is hypothesized that the complete response rate with the use of 12 Gy in 6 daily fractions is 80% (10% total width of the confidence interval) at 3 months. This phase II study will evaluate whether an intermediate dose for follicular lymphoma is associated with excellent response rates while minimizing acute and late toxicity.
Desmoid tumors (DT) are rare disease of intermediate malignancy with variable and often unpredictable clinical course. There is a growing interest in defining potential risk of recurrence or progression during or after pregnancy and in identifying potential obstetrical risks and infertility rate of desmoid patients. Aim of the study: - to define the impact of pregnancy on diagnosis, progression and recurrence of DT; - to define the risks related to DT of obstetrical risks and decisions to interrupt or avoid pregnancy after the diagnosis of DT.
