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.
Bone fractures in traumatic brain-injured and spinal cord-injured patients often heal faster than in other patients. However, such patients are also occasionally prone to bone formation in soft tissues such as muscle. This process is called heterotopic ossification and tends to occur around joints. Patients with heterotopic ossification often suffer from complications such nerve compression, ankylosis, chronic pain, osteoporosis, and infections. Loss of movement can also interfere with function and the quality of life of patients already experiencing difficulties associated with their trauma. Positioning, transfers, and hygiene become difficult and even impossible, which worsens the loss of autonomy. Previous research has suggested that an osteoinductive factor (which has the capacity to induce the formation of bone) may be released into the bloodstream following a head or spinal cord injury. The investigators laboratory has shown that a growth factor called BMP-9, when injected into a damaged mouse muscle, has the ability to cause strong ossification in damaged muscle. The investigators would like to find out whether the levels of BMP-9 and/or its receptor (which is called ALK1) increase after traumatic brain and spinal cord injuries that occur at the same time as serious orthopaedic traumas. The main goal of the investigators study is thus to determine whether BMP-9 levels increase in the serum of trauma patients.
Treprostinil subcutaneous (under the skin) infusion is a very good medication for treating pulmonary arterial hypertension but infusion site pain may be very severe in some patients. The investigators plan to treat patients receiving treprostinil with a subcutaneous infusion of lidocaine (a local anesthestic) to treat the pain.
The Exalenz clinical investigation is a multicenter, non-randomized, study of the ¹³C-Octanoate Breath Test (OBT). The present study is a feasibility trial, which aims to evaluate the capability of the OBT measurement to differentiate between presence and absence of HCC determined by Magnetic Resonance Imaging (MRI) in patients with chronic liver disease.
For many patients with blood cancers, stem cell transplantation from a family member or from an unrelated donor remains the only potentially curative option. Unfortunately, up to 40% of patients develop chronic lung disease after the transplant, which substantially increases the risk of death in the long-term. Currently, patients with transplant-related lung disease are treated with some combination of steroids and other immunosuppressant drugs, but only about 1 out of 5 improve. The importance of our study is that the investigators aim to prevent the development of transplant-related chronic lung disease in the first place. Because a strong risk factor for such chronic lung disease is a prior viral respiratory tract infection, the investigators think there is a window of opportunity to intervene. As soon as "cold and flu" symptoms start, the investigators will treat patients with a combination of drugs aimed at eliminating damaging immune responses triggered by the virus. In the absence of such treatment, the investigators believe these lung-damaging immune responses would persist even after the virus disappears. Our hope is that preventive treatment might avoid the development of chronic lung disease, and this would substantially increase long-term survival in our transplant patients. This is a pilot study. Once feasibility is established, the investigators will seek to expand this study into a definitive clinical trial.
Individuals with kidney disease are at a higher risk for heart and vascular diseases, including heart attacks and strokes, than those with normal kidney function. The purpose of this research study is to collect information on the causes, complications and treatment of kidney disease. Patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data will be collected to examine relationships between biochemical and genetic markers and cardiovascular risk. Information on the health history of incident hemodialysis and peritoneal dialysis patients will be captured using structured patient interviews and review of medical records. Blood and urine specimens will be collected at the time of dialysis initiation and stored in order to perform novel biochemical and genetic assays in the future. The overall goal of the CKDCS/LUCID study is improve understanding of cardiac-associated risks and to improve treatment in patients with kidney disease. A cardiac imaging substudy will be performed in a subset of patients enrolled. The goals of the substudy are to examine whether the risks of developing common cardiac-related complications (coronary artery calcification [CAC] and left ventricular hypertrophy [LVH]) are associated with certain medications taken by individuals on dialysis and whether these risks are modified by a genotypic predisposition.
The main objective of this study is to assess the effectiveness and costs of magnetic resonance cholangiopancreatography (MRCP) and compare it to endoscopic retrograde cholangiopancreatography (ERCP) in the work up of patients with suspected bile duct obstruction on ultrasound. The investigators do not anticipate that a universal recommendation for a given diagnostic test (MRCP versus ERCP) will be applicable in all patients presenting with bile duct obstruction. Rather, the investigators hope to provide quantitative and comparative data relevant to the different clinical situations likely to be encountered in practice, in order to assist physicians in choosing the appropriate diagnostic modality. More specifically, the investigators feel that patients with intrahepatic or hilar obstruction (particularly those with malignant conditions), and those with partial common bile duct (CBD) obstruction (to rule out suspected choledocholithiasis) will benefit most from this new technology and the avoidance of an unnecessary ERCP to further determine the biliary anatomy.
The purpose of this study is to see if pralatrexate extends response and survival following CHOP-based chemotherapy (CHOP: cyclophosphamide, doxorubicin, vincristine, and prednisone) and if pralatrexate improves response in patients with partial response following CHOP-based chemotherapy. Patients will either receive pralatrexate or be under observation. All patients will receive vitamins B12 and folic acid and attend regular clinic visits to evaluate their disease and health.
This study will sought to determine if limited urine collections can provide similar or more informative data than standard 24-hour urine collections used to evaluate kidney stone formers.
This study will investigate the individual safety and efficacy of two dual PI3K/mTOR inhibitors in patients with recurrent endometrial cancer.
This is a Phase 3b, multicenter, international study conducted in 2 parts. Upon completion of the placebo-controlled period (Part 1), participants will have the option of enrolling in a 2-year open-label extension (Part 2). Part 1: The primary objective of the study is to investigate whether treatment with natalizumab slows the accumulation of disability not related to relapses in participants with secondary progressive multiple sclerosis (SPMS). The secondary objectives of Part 1 of this study are to determine the proportion of participants with consistent improvement in Timed 25-Foot Walk (T25FW), the change in participant-reported ambulatory status as measured by the 12-item MS Walking Scale (MSWS-12), the change in manual ability based on the ABILHAND Questionnaire, the impact of natalizumab on participant-reported quality of life using the Multiple Sclerosis Impact Scale-29 Physical (MSIS-29 Physical), the change in whole brain volume between the end of study and Week 24 using magnetic resonance imaging (MRI) and the proportion of participants experiencing progression of disability as measured by individual physical Expanded Disability Status Scale (EDSS) system scores. Part 2: The primary objective of Part 2 of the study is to evaluate the safety profile of natalizumab in participants with SPMS. The secondary objectives of Part 2 of the study are to investigate long-term disability (based on clinical or patient-reported assessments) in participants with SPMS receiving natalizumab treatment for approximately 4 years and to assess change in brain volume and T2 lesion volume.
