The purpose of this study is to determine the safety, tolerability, and pharmacokinetics of 500 mg oral BID dose of KD025 in healthy male and post-menopausal female participants.
The purpose of this study is to determine the safety, tolerability, and pharmacokinetics of multiple oral doses and regimens of KD025 in healthy male and post-menopausal female participants.
The investigators will conduct a randomized controlled trial (RCT) to examine how an online training and peer support platform could help the preparation to transition to adult care. Among 14-16 year old youth with Type 1 Diabetes (T1D), the investigators aim to assess the effect of an online training and peer support platform (Support-t) integrated in usual care, compared with usual care on Hemoglobin A1c (HbA1c), adverse outcomes and psychosocial measures during the preparation for transition to adult care. The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority RCT of adolescents with T1D (14-16 years of age) followed at one of 4 university teaching hospital-based pediatric diabetes clinics in the province of Quebec.
The purpose of this observational research study is to better understand immune responses to vaccines against viruses (influenza or SARS-CoV2). The goal is to determine any differences in immune responses to vaccines in uninjured people and in people living with spinal cord injuries, who are typically at increased risk of infections.
Systemic rheumatological diseases often occur in young women of childbearing age and can therefore impact fertility. There are diseases, such as arthritis, which present no contraindication to assisted reproductive techniques (ARTs), because there is no influence on the disease itself if the disease activity at conception is stable. On the other hand, patients suffering from connective tissue diseases, primarily Systemic Lupus Erythematosus (SLE) and patients suffering from primary or SLE-related Anti-Phospholipid Antibody Syndrome (APS), deserve more targeted therapies both in the context of ARTs and in the ensuing pregnancy. To evaluate the response to ARTs in patients with systemic rheumatological diseases, both in terms of reactivation of the underlying pathology and in terms of ARTs outcome.
The purpose of this study is to evaluate safety and pharmacokinetics (PK) effect of belumosudil on the uridine diphosphate glucuronosyltransferase (UGT)1A1 (Part 1), P glycoprotein (P-gp) (Part 2) and breast cancer resistance protein (BCRP)/organic anion transporting polypeptide (OATP)1B1 (Part 3) inhibition in the fed state in healthy male subjects.
Inborn Errors of Immunity (IEI) include clinically heterogeneous rare genetic diseases depending on mutations in about 300 different genes. Clinically, this group of diseases is characterized by the presence of infectious, inflammatory, autoimmune, and lymphoproliferative symptoms. Understanding the pathogenesis of these diseases can guide the implementation of targeted therapies and improve prognosis. In recent years, IEI have been described that do not necessarily present with repeated infectious symptoms but rather with autoimmune, lymphoproliferative, and autoinflammatory manifestations, or with forms of immunodeficiency with a spectrum of susceptibility to one or few infectious agents. In this case, simple laboratory tests are not sufficient to characterize the disease since no particular immunophenotypic changes are evident. To correct classify the patients and to improve knowledge on the pathogenesis of the diseases, complex immunologic-functional studies are required. These studies should be started prior to genetic analysis, with the aim of targeting and narrowing it down. Although the ever-decreasing costs of Next Generation Sequencing (NGS) methods make it convenient to analyse many genes or even the entire exome simultaneously, the analysis of the data resulting from NGS can be complex and provide results of uncertain interpretation. In these cases, immunologic-functional studies can clarify the real causal role of the identified genetic variants. The identification of genotype-phenotype correlation is crucial to establish new therapeutic targets for diseases orphan of specific etiological treatments. In vitro and in vivo disease models are key tools to test drugs repositioning, as was the case for Lapaquistat in the treatment of periodic fevers caused by de-regulation of the cholesterol metabolic pathway.
Over the past 10 years, the rates of multiple sclerosis (MS) have nearly doubled in the United States. This chronic, neuroinflammatory, and neurodegenerative disease is most often diagnosed between the ages of 20-40. Cognitive impairment effects up to 70% of people with MS (PwMS) and has a detrimental impact on mental health, social connections, and employment. Further, up to 50% of PwMS also struggle with depression. Numerous cognitive rehabilitation programs are available to address cognitive impairment, but few interventions have simultaneous effects on cognition and emotional well-being. Music interventions have potential to fill this gap. Brain imaging studies on music and emotion show that music can modulate activity in the brains structures that are known to be crucially involved in emotion. Further, music engages areas of the brain that are involved with paying attention, making predictions, and updating events in our memory. The purpose of this study is to determine the feasibility of an online musical training intervention (MTI) for PwMS and explore the potential effect on cognition, psychosocial, and functional well-being compared to an active control group (music listening (ML)). The specific aims are to: 1) determine the feasibility and acceptability of delivering the MTI virtually over three months to PwMS; 2) evaluate the effect of the MTI on cognitive functioning (processing speed, working memory, cognitive flexibility, response inhibition), psychosocial (anxiety, depression, stress, quality of life, self-efficacy) and functional (insomnia) well-being compared to ML; and 3) (exploratory aim) to utilize non-invasive neuroimaging to determine if pre-intervention brain activity predicts post-intervention cognitive functioning.
The researchers are doing this study to find out whether emapalumab or a combination of fludarabine and dexamethasone are effective in preparing people with a primary immune regulatory disorder (PIRD) and/or an autoinflammatory condition to receive a stem cell transplant. The researchers will look at how well the study treatments reduce inflammation and aid in the engraftment process (the process of donated stem cells traveling to the bone marrow, where they begin to make new immune cells.
