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 Parkinson Progression Marker Initiative (PPMI) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson's disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.
The recent COVID-19 pandemic has affected many aspects of individuals social life and its negative consequences on Canadian public health go far beyond the direct overload of the hospital care system. Self-isolation and financial uncertainty can significantly deteriorate individuals' mental health, which is only going to aggravate with prolonged physical distancing strategies. Adding to this is the personal and public trauma of lost lives and soon there will be an unprecedented epidemic of mental health problems with crushing effects on the public health sector and economy. To meet this huge new demand for an already strained health system, there is a need for innovative new approaches that significantly expand the capacity of care delivery. While it may not be possible in the short term to increase the number of mental healthcare providers or the number of hours they work, improving their time spent efficiently might be the solution. Virtual care and online delivery of psychotherapy, shown to be clinically effective, efficient and cost-effective, might be the perfect solution to address the high demand faced now. The investigators aim to establish the first academic online psychotherapy clinic to manage mental health problems secondary to COVID-19. The goal is to evaluate the feasibility and efficacy of treating COVID-19 related mental health issues in this clinic, offering a 10-week, diagnosis-specific, online psychotherapy program. The investigators will use the Online Psychotherapy Tool (OPTT), a secure cloud-based digital mental health platform, developed by the PI, Dr. Alavi. Potentially, this method of care delivery could increase care capacity by four-folds. The findings from this project have the potential to influence clinical practice and policy and increase accessibility to care during COVID-19 pandemic, without sacrificing the quality of care.

To evaluate the efficacy and safety of INCB054707 in participants with hidradenitis suppurativa over a 16-week placebo-controlled treatment period followed by a 36-week open-label extension period. All eligible participants will be invited to continue treatment for an additional 48-week Long-term extension period (also open label).
This study will follow participants who are screened and confirmed with a genetic diagnosis of Limb-girdle muscular dystrophy type 2E (LGMD2E/R4), Limb-girdle muscular dystrophy type 2D (LGMD2D/R3), Limb-girdle muscular dystrophy type 2C (LGMD2C/R5), or Limb-girdle muscular dystrophy type 2A (LGMD2A/R1). These enrolled participants will be followed to evaluate mobility and pulmonary function for up to 3 years after enrollment. Additional participant data will be collected from the time the individual began experiencing LGMD symptoms to the present.
To determine the safety of antithrombotic treatment discontinuation 12 months following successful transcatheter PFO closure.
The purpose of this study is to determine if performing radiotherapy (SRS) prior to surgery results in better treatment outcomes than performing surgery before radiotherapy for patients with brain metastases. Brain metastases occur when cancer cells from a primary cancer (e.g. lung, breast, colon) travel through the bloodstream and spread (metastasize) to the brain. As these new tumors grow they apply pressure and change how healthy brain tissue works. This can lead to a loss of brain function and worsening quality of life. Treatments for patients whose cancer has spread to the brain is often surgery, radiation therapy (radiotherapy) or a combination of both. Surgery is one the main treatments for brain tumors. To remove the tumor, a neurosurgeon makes an opening in the skull and attempts to the remove the entire tumor. If the tumor is too close to important brain tissue, the surgeon may attempt to remove part of the tumor. Removal of the tumor from the brain tissue is called resection. The complete or partial removal of tumor helps to relieve symptoms by reducing pressure on healthy tissues and reduces the amount of tumor that needs to be treated by radiotherapy. One type of radiotherapy used to treat brain metastases is stereotactic radiosurgery (SRS). SRS uses many focused radiation beams to treat tumors within the brain. Unlike surgery, there is no incision or cut being made. Instead, SRS uses an accurate map of your brain to deliver a precise beam of radiation to the tumors. The radiation damages the tumor cells forcing them to shrink and die off. The focused radiation beams also limit damage to healthy brain tissue minimizing side effects. Surgery followed by radiotherapy is a standard treatment for brain metastases. However, there are still risks associated with the combination of treatments. This study plans to investigate whether performing surgery prior to SRS results in improved quality of life and decreased side effects.
This randomized, double-blind, placebo-controlled trial will seek to determine the efficacy of abatacept in GCA. To examine this objective, 62 eligible patients who have newly diagnosed or relapsing GCA within 8 weeks prior to screening will be randomized at a 1:1 ratio to receive subcutaneous abatacept 125mg/week or placebo. Patients who achieve remission will remain on their blinded assignment for 12 months at which time abatacept/placebo will be stopped. Patients who do not achieve remission by Month 3, who experience a relapse within the first 12 months will have the option of receiving open-label abatacept for a maximum of 12 months.
A)Background: Approximately 44% of patients with Inflammatory bowel disease have Ulcerative colitis(UC) which is a lifelong, chronic disease, starting in early adulthood, where the colon becomes inflamed and ulcerated due to a complex interaction between genetics, altered immune function, and environmental factors2such as dietary intake. While the etiology of UC is not clear, it is hypothesized the abnormal immune response and chronic inflammation may be caused by dysbiosis of the intestinal microbiota and decreased epithelial barrier function. Substantial evidence suggests that higher than normal levels of hydrogen sulfide (H2S) in the colon plays a role in the etiology of UC. The higher levels of H2S and sulfate-reducing bacteria (SRB) found in the feces of patients with UC is likely caused by the reduced conversion of H2S to thiosulfate by rhodanese (thiosulfate transferase enzyme)12, and increased colonization or activity of SRB. For example, SRB has been identified as the predominant bacterial group in patients with UC compared to the minority group in healthy individuals, and SRB growth is stimulated by the presence of sulfur-rich amino acids. Dietary intervention may help to repair the dysbiosis existing in the microbiome of the patient with UC, but research about food and recurrence of UC is conflicting. Dietary components such as sulfur and sulfates also appear to play a role in the recurrence of UC; although a recent review of the relationship between sulfur-containing foods and UC calls for more randomized controlled trials (RCTs) examining a reduced sulfur diet in UC. With the body of evidence described above, there is a compelling reason to consider that sulfur and sulfate-containing foods contribute to developing severe UC. Thus, understanding how dietary modulation of sulfur intake within the context of UC impacts disease status is the focus of this proposal.
Fetal complete (i.e., third degree, 3°) atrioventricular block (AVB), identified in the 2nd trimester of pregnancy in an otherwise normally developing heart, is almost universally associated with maternal anti-Ro autoantibodies and results in death in a fifth of cases. To date treatment of 3° AVB has been ineffective in restoring normal rhythm (NR) which may be because current surveillance is limited to once- weekly fetal echocardiograms. It is hypothesized that there may be a vital transition period of several hours in which incomplete block (2° AVB) may be successfully treated avoiding fully advanced irreversible 3° AVB. To optimize the likelihood of timely detection of the transition period this study comprises three steps: 1) to risk stratify for high titer anti-Ro antibodies, which are necessary but not sufficient to develop fetal AVB; 2) to empower mothers to identify 2° AVB by using fetal heart rate and rhythm monitoring (FHRM) at home, and 3) to rapidly treat mothers who detect an abnormality by monitoring with an urgent echocardiogram that confirms 2° AVB with the hope of reversing 2° AVB before it becomes permanent (3° AVB). In addition, it will be determined if FHRM reduces the need for weekly echoes. Although mothers with low titer anti-Ro will not be continued in Step 2 and therefore not followed by FHRM, birth ECGs will be collected to confirm that low titer antibodies do not confer risk. It is anticipated that this study will provide an evidenced based surveillance strategy for those mothers at high risk of having a child with 3° AVB.
