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.
The primary objective of this study is to assess the safety and efficacy of risankizumab 180 mg and 360 mg versus placebo for the treatment of signs and symptoms of moderate to severe hidradenitis suppurativa (HS) in adult participants diagnosed for at least one year before the Baseline visit.
The reason for this study is to see if the study drug mirikizumab is safe and effective in participants with moderately to severely active Crohn's disease.
The main purpose of this study are to determine the recommended Phase 2 dose (RP2D) regimen and the maximum tolerated dose, and to determine the safety of JNJ-63898081.
The purpose of this study is to evaluate a recovery-oriented group counselling program for post-discharged critical illness survivors and their caregivers.
Quality of life of people living with HIV is strongly affected by the presence of one or more symptoms, such as sleep problems, fatigue, muscle pain, anxiety and depressive symptoms. Autogenic training has shown positive effects on these symptoms in different populations, but there is very little evidence on the effects of this relaxation technique in people living with HIV.
This is a study of perioperative pembrolizumab or enfortumab vedotin in combination with pembrolizumab in participants who are cisplatin-ineligible or decline cisplatin with muscle-invasive bladder cancer (MIBC). The primary hypothesis is that perioperative pembrolizumab plus radical cystectomy (RC) plus pelvic lymph node dissection (PLND) and perioperative enfortumab vedotin in combination with pembrolizumab plus RC+PLND will achieve superior event-free survival (EFS) compared with RC+PLND alone. With Amendment 5, outcome measures for programmed cell death ligand 1 (PD-L1) combined positive score (CPS) were removed. With Amendment 8, the primary outcome measure of pathologic complete response (pCR) rates was changed to a secondary outcome measure.
The purpose of this study is to assess the efficacy and safety of stereotactic body radiotherapy (SBRT) plus pembrolizumab (MK-3475) in the treatment of adult participants with unresected stage I or II (Stage IIB N0, M0) non-small cell lung cancer (NSCLC). The primary study hypothesis is SBRT plus pembrolizumab prolongs Event-free Survival (EFS) compared to SBRT plus placebo (normal saline solution).
A global study to evaluate peri-operative pembrolizumab with chemotherapy versus placebo to pembrolizumab plus chemotherapy in cisplatin eligible patients.
Despite being studied less than half as frequently, autonomic dysfunction is a greater priority than walking again in spinal cord injury. One autonomic condition after spinal cord injury is orthostatic hypotension, where blood pressure dramatically declines when patients assume the upright posture. Orthostatic hypotension is associated with all-cause mortality and cardiovascular incidents as well as fatigue and cognitive dysfunction, and it almost certainly contributes to an elevated risk of heart disease and stroke in people with spinal cord injury. In addition, autonomic dysfunction leads to bladder, bowel, sexual dysfunctions, which are major contributors to reduced quality and quantity of life. Unfortunately, the available options for treating this condition, are primarily limited to pharmacological options, which are not effective and are associated with various side effects. It has been recently demonstrated that spinal cord stimulation can modulate autonomic circuits and improve autonomic function in people living with spinal cord injury. Neuroanatomically, the thoracolumbar sympathetic pathways are the primary spinal cord segments involved in blood pressure control. Recently, a pilot study has been published demonstrating that transcutaneous spinal cord stimulation of thoracolumbar afferents can improve cardiovascular function. However, some studies have shown that lumbosacral transcutaneous spinal cord stimulation can also elicit positive cardiovascular effects. Therefore, there is no consensus on the optimal strategy in order to deliver transcutaneous spinal cord stimulation to improve the function of the autonomic system, and it may be that lumbosacral (i.e. the stimulation site being used most commonly for restoring leg function is sufficient). Another key knowledge gap in terms of transcutaneous spinal cord stimulation is whether or not the current is directly or indirectly activating these spinal circuits. Last but not least, the effects of epidural spinal cord stimulation on the function of cardiovascular, bladder, bowel and sexual system in spinal cord injury have been investigated in no study yet. AIMS AND HYPOTHESES: Aim 1. To examine the effects of short-term (one session) transcutaneous spinal cord stimulation on the frequency and severity of episodes of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. These effects will be compared at two sites of stimulation. Hypothesis 1.1: Short-term transcutaneous mid-thoracic cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 1.2: Lumbosacral transcutaneous spinal cord stimulation will improve bladder, bowel, and sexual functions. Aim 2. To examine the effects of long-term (one month) transcutaneous spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 2.1: Long-term stimulation of the mid-thoracic cord will result in sustained improvements in mitigated severity and frequency of orthostatic hypotension/autonomic dysfunction that is not dependent on active stimulation. Hypothesis 2.2: Long-term lumbosacral transcutaneous spinal cord stimulation will result in sustained improvements in bowel, bladder, and sexual function that is not dependent on active stimulation. Aim 3: To examine the effects of short-term (one session) epidural spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. Hypothesis 3.1: Epidural spinal cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction and improve bladder, bowel, and sexual function. Hypothesis 3.3: There is no significant difference between immediate effects of lumbosacral transcutaneous spinal cord stimulation and epidural spinal cord stimulation on bladder, bowel, and sexual function. For aim 1, 14 participants with spinal cord injury and no implanted electrodes on the spinal cord will be recruited. Participants will randomly receive one-hour stimulation under each of the two stimulation conditions in a crossover manner: Mid-thoracic and Lumbosacral. For aim 2, 28 individuals with spinal cord injury and no implanted electrode will be pseudo-randomized (1:1) to one of two stimulation sites. Participants will receive one-hour stimulation, five sessions per week for four weeks. Cardiovascular and neurological outcomes will be measured before the first stimulation session and after the last stimulation session. For aim 3, 4 participants with spinal cord injury with implanted electrodes on the spinal cord will be recruited to study the immediate effects of invasive epidural spinal cord stimulation. All outcomes will be measured in two positions: a) Supine, b) ~ 70° upright tilt-test. Additionally, bowel, bladder, and sexual functions in project 2 will be assessed weekly.
The purpose of this study is to determine the effective regimen for definitive surgical therapy of bilateral kidney stones. It is unknown whether patients who undergo simultaneous bilateral percutaneous nephrolithotomy (PCNL) experience improved post-operative outcomes compared to patients who have staged unilateral procedures.
