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 will evaluate the ability of the vaccine to produce antibodies against herpes zoster virus (shingles) and safety of vaccination with Varicella Zoster Vaccine in patients with moderate to severe psoriasis who will initiate biologic therapy 4 to 6 weeks after vaccination. Varicella Zoster Vaccine will be administered 4 to 6 weeks prior to receipt of biological therapy and will be compared against placebo. This double-blind study will enroll approximately 50 adult patients with moderate-to-severe plaque psoriasis in approximately 3 centers in Canada. Study products will be assigned randomly at a 4:1 ratio. For each patient who is included, the study may last up to 22 weeks, including the screening and the follow-up period. During the study, subjects will come to the dermatology clinic up to 4 occasions: for a screening visit, Baseline visit, Day 42 as well as 84 days after they started taking the biological treatment for a last visit. If patients develop a varicella-like or shingles-like rash at any time after they received the vaccine, they will be requested to come back to the clinic within 72 hours of rash onset (preferably within 24 hours) for examination. Subjects will be asked to provide a lesion swab/vesicular fluid in this case.
In this study the investigators hypothesize that antidepressant therapy may improve the overall welling of patients with acute or chronic kidney disease when given around the time of starting chronic dialysis therapy. This study is a pilot, randomized controlled trial that aims to examine whether prescribing oral escitalopram to all incident dialysis patients is safe and feasible.
This study will primarily evaluate the safety and efficacy of andecaliximab in adults with active Crohn's disease. The study will consist of a Double-Blind Phase of 8 weeks followed by an Open-Label Extension. Participants who complete the Double-Blind Phase will be eligible to enroll in the optional Open-Label Extension for an additional 44 weeks. Participants who complete Week 52 assessments will be eligible to enter the Extended Treatment Phase to continue treatment with andecaliximab for an additional 156 weeks.
The primary objective of this study is to evaluate the safety of entospletinib in combination with vincristine (VCR), and dexamethasone (DEX) in adults with previously treated relapsed or refractory B-cell lineage acute lymphoblastic leukemia (ALL). This is a dose escalation study in which after 2 induction cycles participants may be put on maintenance for up to 36 cycles if they have obtained clinical benefit from the treatment.
This open-label extension and safety monitoring study is composed of two parts: Part 1 will evaluate the long-term safety and efficacy of continued etrolizumab treatment in participants with moderately to severely active Crohn's disease who were previously enrolled in the etrolizumab Phase III Study GA29144 (NCT02394028) and who meet eligibility criteria for enrollment into Part 1. In Part 2, participants who have stopped etrolizumab treatment (either by exiting Part 1 of this study or by entering directly from Study GA29144 [NCT02394028]) will be monitored for 92 weeks for progressive multifocal leukoencephalopathy (PML) and other safety events.
This study seeks to better characterize relationships between visual function and the progression (worsening) of geographic atrophy (GA) due to age-related macular degeneration (AMD). The study also will generate new information on the relationship between genetics and GA progression. This is a global, prospective, multicenter, epidemiologic study enrolling 200 participants with GA secondary to AMD. The study visits are scheduled to occur every 6 months. The anticipated duration of the study is up to 60 months.
Phase I/II study to assess the safety and performance of the Amphora OAB system for treatment of urgency and frequency with or without urge incontinence caused by an overactive bladder.
This is a medical research study designed to look at the safety and efficacy of 30-day course of fidaxomicin for treatment of recurrent CDI (Clostridium difficile Infection). CDI is an infection that results when the normal flora (resident bacteria) of the colon is substantially altered by antibiotic treatment. The decrease in this normal flora allows for the growth of the C. difficile bacteria. Fidaxomicin is an antibiotic which is approved by Health Canada for treatment of CDI. Only patients with a primary case of CDI or 1st episode of recurrent CDI have been studied using a 10-day course of fidaxomicin.
Epidural analgesia is highly effective for labor pain relief and is widely chosen by pregnant patients. However, placement of the epidural needle can be challenging in pregnant patients due to lax tissue ligaments and edema so that the traditional loss of resistance method (LOR) used to find the space may be subtle leading to retries which may delay onset of analgesia as well as increase the risk of complications. The ability to transduce a pulsatile pressure waveform from epidural needles placed in non-laboring patients correlates highly with successful placement of the epidural needle. We wish to evaluate the efficacy of obtaining a pulsatile pressure waveform with correct epidural needle placement in laboring women.
The primary goal of this proposal is to study the outcome of patients with recurrent Clostridium Difficile Infection (CDI) treated with frozen Fecal Microbiota Transplantation (FMT) in an open-labelled controlled trial. The specific objectives are to evaluate the safety of FMT and to determine the clinical response, treatment failure and relapse rate in patients treated with frozen-and-thawed FMT; to assess the functional health and well-being of patients in each arm using the validated tool, and to determine the feasibility of providing standardized FMT in multiple centres across Canada, including community hospitals. The metagenomics will also be conducted from the stool samples collected from select patients from each arm: pre and post treatment and the matching donors. The metagenomics data will be used to determine the bacteria which may have contributed to the cure of CDI.
