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 study is designed to evaluate the clinical changes in gingival health by measuring the reduction of gingival bleeding and inflammation over 4 weeks. Additionally, plaque removal will be evaluated after a single use (part 1) and over 4 weeks (part 2).
This phase III trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Whole brain radiation therapy delivers a low dose of radiation to the entire brain including the normal brain tissue. Hippocampal avoidance during whole-brain radiation therapy (HA-WBRT) decreases the amount of radiation that is delivered to the hippocampus which is a brain structure that is important for memory. The drug, memantine, is also often given with whole brain radiotherapy because it may decrease the risk of side effects related to thinking and memory. Stereotactic radiosurgery may decrease side effects related to memory and thinking compared to standard of care HA-WBRT plus memantine.
This study will assess the safety and efficacy of ARQ-151 cream applied once a day for 52 weeks by subjects with atopic dermatitis (eczema).
The variable clinical outcome of patients with G2 & G3 well diff GEP-NETs makes the selection of an optimal treatment strategy challenging. Initial data suggests that high DOTATATE uptake and low FDG uptake are suggestive of low grade disease, with an indolent course. Conversely, low DT uptake and high FDG uptake are suggestive of high-grade/ aggressive disease. G2/3 GEP NETs may be biologically diverse; clinically relevant cohort for dual-tracer PET imaging. Our secondary objectives are 1. To determine the distribution of PETNET scores derived from 18F-FDG & 68Ga-DT PET in patients with G2 & G3 well diff GEP-NETs. 2. To determine the proportion of patients in whom the addition of 18F-FDG PET data results in a change in planned clinical management. To assess intra-individual variability in SSTR expression & glucose metabolism (as seen on DT and FDG PET) across different tumor sites within the same patient. 2) To determine whether a correlation exists between tumor texture features on 68Ga-DT & FDG PET to tumor grade and Ki 67 index. 3) To assess for an association between tumor texture features on 68Ga-DT PET and glucose metabolism; and/or an association between tumor texture features on FDG PET and SSTR expression.
Crohn's disease (CD) is a lifelong incurable condition that causes inflammation of the intestinal tract of humans. The exact cause of CD is unknown, but genetics, diet, and the gut microbiome are all thought to play a major role. Many patients with CD will require surgery to remove affected portions of the gut, with ileocecal resections being the most common procedure performed. Regrettably, there is up to an 85% chance that disease returns to the surgical site. Strong immune suppressive medications may help to prevent disease relapse. However, patients are then at risk of serious side effects. Currently, no ideal post-op care exists for CD patients. This study aims to assess whether a post-op synbiotic therapy (i.e. probiotics plus dietary fiber) prevents disease relapse in participants with CD. To test this, participants will consume probiotics (strains of bifidobacteria) before their surgery and then probiotics plus fiber supplements after surgery. Probiotics are live bacteria that have been shown to reduce inflammation of the gut. Fiber is given after surgery to help promote beneficial bacterial taxa and prevent less favorable bacterial taxa from triggering CD relapse. Patients will take the supplements for 6 months following surgery. They will be seen monthly to assess the effects of treatment on quality of life, symptoms of disease recurrence, inflammatory markers, and the gut microbiome. All patients will also undergo a colonoscopy at the end of the study to check for endoscopic reoccurrence.
In light of the coronavirus pandemic, the challenge of physician burnout has taken on a new urgency. Long-hours and difficult, sometimes unsafe work conditions are creating a severe strain for emergency physicians and others on the frontlines of Ontario's response to COVID-19. There are a variety of evidence-informed ways that physicians can protect their wellbeing with modest investments of time and energy that will be applied. The evaluation will be a randomized trial comparing the outcomes from each of the three treatment arms. Researchers may also use a pre-post comparison with control parameters to conduct an exploratory analysis to assess efficacy.
A Phase IV trial of a hospital policy of Tranexamic acid to reduce transfusion in major non-cardiac surgery.
Study to compare the effects of the investigational new drug (PF-06946860) and a placebo on appetite and to find out how participants with advanced cancer and anorexia feel after receiving repeated subcutaneous (SC-injected under the skin) doses.
This clinical trial is designed to test whether surgically injecting nerve cells that make dopamine into the brain of Parkinson's disease patients is safe, and to monitor for potential side effects.
Mitochondrial DNA (mtDNA) depletion syndromes (MDS) are a genetically and clinically heterogeneous group of autosomal recessive disorders that are characterized by a severe reduction in mtDNA content leading to impaired energy production in affected tissues and organs. MDS are due to defects in mtDNA maintenance caused by mutations in nuclear genes that function in either mitochondrial nucleotide synthesis. MDS are phenotypically heterogeneous and usually classified as myopathic, encephalomyopathic, hepatocerebral or neurogastrointestinal. No efficacious therapy is available for any of these disorders. Affected individuals should have a comprehensive evaluation to assess the degree of involvement of different systems. Treatment is directed mainly toward providing symptomatic management. No treatment for MDS. Clinical trials studies and in vitro/in vivo research studies showed that the enhancement of the salvage pathway by increasing the availability of deoxyribonucleosides needed for each specific genetic defect prevents mtDNA depletion. Early recognition and immediate therapy to restore mitochondrial function could potentially improve clinical course. Confirming the benefit of deoxynucleosides as a safe and potentially efficacious therapy, will lead to the availability of the first specific and effective treatment for Mitochondria Depletion Disorders. In this phase II Trial a mix of Deoxynucleosides Pyrimidine (Deoxycytidine dC and Deoxythymidine dT) will be used as early treatment of MDS. The dose used has been already used in other clinical trials, and appears to effective and well-tolerated. The subjects included are children (0-18Y), with positive MDS diagnosis and express mutations in one of the following genes: POLG, C10orf2, RRM2B, MPV17, SUCLA2, SUCLG1, FBXL4. Subjects with MDS expressing neurological phenotypes dysfunction.
