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 pilot study is designed as a multi-centre cohort study determining the degree of LV reverse remodeling in patients with intermediate QRS widths (120-149ms) who undergo CRT implant with transseptal LV leads, and comparing to the average expected reverse remodeling rate in patients with standard transvenous coronary sinus leads and QRS widths ≥150ms.
The guided FNA by endobronchial ultrasound ( Endobronchial Ultrasound guided transbronchial Needle Aspiration or EBUS-TBNA) is a minimally invasive technique with an established role in the staging of lung cancer 1, and in the evaluation of intrathoracic lymph node metastases from extrathoracic primary cancer2 . There is also a role in cases of isolated hilar and mediastinal lymph nodes in which the differential diagnosis includes mostly sarcoidosis, lymphoma and tuberculosis. 3 Various studies have evaluated more recently the diagnostic yield of EBUS-TBNA specifically for sarcoidosis 4 and thoracic lymphoma 5-6. Although there is emerging data supporting the usefulness of EBUS-TBNA in the investigation of these two pathologies, the efficacy results vary according to the target populations and certain parameters. Moreover, although a large randomized study demonstrated e superiority of EBUS-TBNA over conventional bronchoscopic sampling methods [ bronchoalveolar lavage (BAL) and trans-bronchial biopsies (TBB ] for the diagnosis of sarcoidosis , 7 the results suggest that there is still room for optimizing the performance of EBUS-TBNA [b] . In the field of lymphoma, obtaining large enough specimens for adequate subtyping also remains a concern. 8 In order to improve the performance of EBUS -TBNA , new needles have been developed with the aim to provide biopsies for histological evaluation rather than purely cytological. The ViziShot FLEX © (Olympus) 19 gauge needle (19 gauge or 19G) is a large needle, which can provide both tissue and needle aspiration , and has the advantage of being more flexible. For this study, the investigators want to compare the diagnostic yield of EBUS-TBNA using needle ViziShot FLEX 19G (1.11 mm) with that of the standard 22G needle ( NA-201SX; Olympus) , in the investigation of hilar or mediastinal lymphadenopathy suspected to be sarcoidosis or lymphoma.
The primary objective of this study was to assess the efficacy and safety of two doses of vilaprisan compared to placebo in women with symptomatic endometriosis. The secondary objective of this study was to evaluate the safety and tolerability of two different doses of vilaprisan in women with symptomatic endometriosis. With the implementation of protocol version 4.0 dated 11-Dec-2018, no new subjects were enrolled. The objectives above cannot be reached as only limited data is available from subjects recruited before the temporary pause.
The purpose of this study is to compare the efficacy and safety of ixekizumab to guselkumab in participants with moderate-to-severe plaque psoriasis.
The purpose of the study is to identify the maximum tolerated dose (MTD) of JNJ-64619178 in participants with relapsed/refractory B cell non-Hodgkin lymphoma (NHL) or advanced solid tumors and also to identify the recommended Phase 2 dose(s) (RP2Ds) of JNJ-64619178 for NHL and advanced solid tumors (Part 1) and to confirm the tolerability of JNJ-64619178 in participants with lower risk myelodysplastic syndromes (MDS) (Part 2).
During end-stage kidney disease, clinical guidelines suggest reducing elevated phosphate levels in the blood. However, the effect of lowering blood phosphate levels on important patient-centred outcomes has never been tested. This trial will evaluate whether compared to high levels, lowering blood phosphate levels would reduce death or major events due to heart disease, improve physical health, and be cost-effective.
Nonalcoholic fatty liver disease is the most common liver disease in Western countries, due in large part to its association with type 2 diabetes and obesity. The more advanced form of this disease is known as nonalcoholic steatohepatitis (NASH). If left untreated, NASH can evolve to cirrhosis, the late stage of fibrosis. Once cirrhosis is established, patients are at increased risk of developing gastrointestinal bleeding, liver cancer and liver failure that may require transplantation. A liver biopsy is currently needed to diagnose the severity of fatty liver disease but this is usually not indicated in asymptomatic patients. This procedure requires the insertion of a needle inside the liver to remove a small piece of tissue for examination under microscope. Liver biopsy is an invasive procedure with a small risk of major complications such as bleeding in 0.5% of cases. It is also affected by sub-optimal sampling leading to diagnostic errors Ultrasound is optimum for screening patients with or without symptoms because it is a safe and widely available technology to scan the whole liver. Members of our team have developed Advanced ultrasound techniques that provide unique information not possible with state-of-the-art techniques. Unlike liver biopsy, these techniques would be applicable even in asymptomatic patients because it is non-invasive. This research proposal proposes a novel approach for diagnosis of NASH and will be the first study to measure individual components of NASH (fat, inflammation and fibrosis) with quantitative ultrasound (QUS) scores. This study is timely because NASH is the second leading cause of liver transplantation in North America and is predicted to become the leading indication in the near future.
Assessment of the upper sensory block level during neuraxial analgesia for labor and delivery is an essential component of clinical management and patient safety. A variety of methods have been used for testing the sensory block such as cold, light touch, sharp touch or prick and transcutaneous electrical stimulation. In addition to the diversity of methods, the endpoints used by investigators have also been variable, considering total or partial responses as endpoints. Not surprisingly, a variable sensory block level could be identified as a result of the different methods and types of question asked by the examiner. Another complicating factor is the lack of standardization of the direction of the testing as it relates to anesthetized and non-anesthetized areas. This lack of standardization may result in a difference of several dermatomes in the level that two different assessors might record for the same patient. Considering a clinical research scenario, it may be difficult to replicate results and implement clinical practices. The objective of this study is to determine the degree of agreement between two methods of assessing the sensory block level to cold in women receiving epidural analgesia for labor (anesthetized to non-anesthetized segments versus non-anesthetized to anesthetized segments).
This observational study will gather outcome and experience data of patients living with advanced colorectal cancer and their caregivers. The primary objective is to measure how quality of life in this population changes over time (before, during, and after a palliative pathway becomes the new standard of care in Calgary, Alberta, Canada).
This study is a randomized controlled trial (RCT) of the Weight Watchers (WW) Freestyle ® (Flex® in UK) weight loss program compared to a control group following a do-it-yourself (DIY) approach for 12 months. Participants in the United States, Canada and the UK (n=360 total) will be randomly assigned to either participate in the commercially available WW program in their local community or to follow their own approach for weight loss. This study will examine the impact of the WW program on weight, fitness levels, quality of life, health behaviors and other health outcomes in overweight and obese adults after 3 and 12 months.
