This randomized controlled comparative effectiveness study examines manipulation of a key component of an established and efficacious treatment for naming impairments in aphasia, along with cognitive and brain correlates of treatment success. Study participants will be randomly assigned to one of two treatment conditions comparing two different versions of Semantic Feature Analysis treatment. Their performance on standardized and study-specific measures will be used to determine which version of the treatment provides superior outcomes, and measures of automatic language processing and functional brain imaging will also be used to identify the underlying neurocognitive mechanisms associated with positive treatment response.

This is single arm study of a window of opportunity in which participants with previously untreated triple negative breast cancers (TNBC) who are candidates for potentially curative surgery will receive lenvatinib 12 mg daily for 7 and pembrolizumab 200 mg IV on day 1 prior to surgery

A randomized clinical trial to assess the efficiency of acetylsalicylic acid (aspirin) 150 mg/day started before 20 weeks of gestation in the prevention on maternal and fœtal complications in pregnant women with chronic hypertension.

GNB5 is an investigator-initiated multicentre non-inferiority randomized controlled trial which aims to assess the efficacy and safety of shortened antibiotic for patients hospitalized with a Gram negative bacteremia with a urinary tract source of infection (GNB). Five days after initiation of antimicrobial therapy for GNB, participants are randomized 1:1 to parallel treatment arms: 5 days (intervention) or minimum 7 days (control) of antibiotic treatment. The intervention group discontinues antibiotics at day 5 if clinically stable and afebrile. The control group receives antibiotics for a duration of 7 days or longer at the discretion of the treating physician. The primary outcome is 90-day survival without clinical or microbiological failure to treatment, which will be tested with a non inferiority margin of 10%.

The I-MAT trial is a randomised, placebo-controlled, phase II trial of adjuvant Avelumab in patients with stage I-III Merkel cell carcinoma aiming to explore the efficacy of avelumab as adjuvant immunotherapy.

This is a proposal, for the first time in Canada, to examine the comparative effectiveness of three commercially available devices (ASO, FSO, and GAO/GSO) for transcatheter closure of atrial septal defects (ASD) in adults using a pilot randomized controlled trial.

Long-term weight loss maintenance is seldom achieved by individuals with obesity owing to numerous biological adaptations occurring in the post-weight loss setting, including neuroendocrine-mediated changes in appetite/satiety and reduction of energy expenditure. Following weight loss, peripheral and central mechanisms respond in a way similar to starvation by conveying a sense that energy reserves have dwindled, activating a strong counter-response to increase caloric intake. Moreover, metabolic rate drops, further compounding the propensity for weight rebound. Adolescents with severe obesity are not immune to the vexing issue of weight regain; therefore, effective and scalable treatments are urgently needed. Pharmacotherapy has the potential to prevent weight regain by targeting counter-regulatory mechanisms in the post-weight loss setting. Unfortunately, only one obesity medication is FDA-approved for long-term use in adolescents and is seldom prescribed owing to modest efficacy and notable side effects. Among the most promising candidates in the pediatric pipeline is the combination of phentermine and topiramate, which is the most effective adult weight loss medication currently available. The mechanisms of action are thought to reduce appetite, enhance satiety, and potentially increase energy expenditure, making this medication particularly well-suited for the purpose of weight loss maintenance since it targets many of the biological adaptations known to induce relapse and subsequent weight regain. The investigators have generated preliminary data demonstrating that both phentermine and topiramate reduce BMI in adolescents with severe obesity and have acceptable safety profiles. In this clinical trial, the investigators will utilize combination phentermine/topiramate to target counter-regulatory pathways responsible for weight regain after meal replacement therapy (structured meals of known caloric content) in adolescents with severe obesity with a goal of enhancing weight loss maintenance and improving obesity-related complications. Importantly, the investigators will maximize the clinical utility and overall impact of the study by comprehensively characterizing the safety of phentermine/topiramate utilizing sensitive measures of cardiac autonomic function, arterial stiffness, cognition, and bone health as well as examine the extent to which this medication counteracts mechanisms of weight regain.

This Phase II study is designed to study the clinical and radiologic response, as well as, safety and tolerability of abemaciclib in combination with androgen deprivation therapy (ADT) in patients with localized high-risk or locally advanced prostate cancer who are eligible for definitive radiation therapy (RT) and androgen deprivation therapy (ADT).

The purpose of the study is to evaluate the efficacy and safety of tiragolumab plus atezolizumab compared with placebo plus atezolizumab in participants with previously untreated locally advanced, unresectable or metastatic PD-L1-selected non-small cell lung cancer (NSCLC), with no epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) translocation. Eligible participants will be randomized in a 1:1 ratio to receive either tiragolumab plus atezolizumab or placebo plus atezolizumab.
