Filter by:This Phase 1b basket trial will investigate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and preliminary efficacy of RAY121, a inhibitor of classical complement pathway, after multiple dose administration in patients with immunological diseases such as antiphospholipid syndrome (APS), bullous pemphigoid (BP), Behçet's Syndrome (BS), dermatomyositis (DM), immune-mediated necrotizing myopathy (IMNM) and immune thrombocytopenia (ITP).
This study is to describe the real-world treatment patterns and clinical outcomes in moderate-to-severe AD patients receiving abrocitinib over a 12-month observation period, and to describe patient demographic and baseline characteristics.
This pilot study will individually randomize 105 adolescents living with HIV 1:1:1 to standard of care, adapted intervention, or enhanced intervention. The intervention is called the Friendship Bench Intervention is a counseling intervention for depression and engagement in HIV care.
The pandemic associated with the SARS-CoV-2 coronavirus has affected over 760 million individuals worldwide, resulting in more than 6.9 million deaths. France has also been heavily impacted, with over 39.8 million infections and 167,000 deaths. SARS-CoV-2 primarily causes an upper respiratory tract infection transmitted through the air. When it reaches the lungs, it leads to a severe acute respiratory illness called COVID-19. The body's response to this viral assault primarily occurs at the level of the respiratory mucosa. This mucosal response is complex, involving various levels of activity. Mucosal immunity is therefore essential for an adequate and long-term immune response against viral respiratory infections, including SARS-CoV-2 infection. Infection with SARS-CoV-2 triggers a humoral immune response with the production of antibodies in the blood (serum antibodies) and antibodies in the upper respiratory tract (mucosal antibodies). It also induces a cellular immune response by activating specific blood T lymphocytes. Tests used to measure the humoral blood response against SARS-CoV-2 and their neutralizing capacity are now well identified, as are tests for assessing the serum cellular T lymphocyte response. However, tests for measuring mucosal immune responses are not routinely used. Our study aims to develop and qualify methods for analyzing mucosal immunity directed against SARS-CoV-2. These methods will be essential for a more precise analysis of the body's mucosal response to this virus. Once these analytical methods are validated, they will enable the study of mucosal responses to infection, as well as mucosal responses induced by vaccination against SARS-CoV-2, particularly in the context of future nasal vaccine use.
The investigators will conduct a trial to evaluate if an online training and support platform can help adults living with type 1 diabetes (T1D) in their diabetes self-management. Investigators will compare a group that has access to the "Support" platform through their usual medical care to a group that accesses the platform independently. The first group will be recruited through four participating clinics in the province of Quebec (Canada). The second group will be composed of adults living with T1D across Canada. Participants will have access to the platform for 12 months and will be asked to complete online questionnaires at the beginning and after 6 and 12 months, and share their glucose reader data with the research team. A subgroup of participants as well as healthcare professionals from the four clinics will be invited to participate in an individual interview aiming to understand the barriers and facilitators of integration "Support" in clinical care.
Ambispective, national, multicenter observational cohort study aimed at characterizing the satellite dysimmune manifestations of clonal hematopoiesis, including Vexas (Vacuoles, E1 enzyme, X-linked, Autoinflammatory and Somatic) syndrome.
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.
Vitamin D deficiency is common among pregnant women, despite daily vitamin D supplements. This study aims to investigate if maternal vitamin D intake of 90 vs 10 µg affects the overall health, growth, and immune system of the offspring at birth and after 1 year. Blood samples at birth and after one year, questionnaires and clinical 1-year examination will be performed on the children.
This research is being done to see if the immune (defense) system of people with Multiple Myeloma and Waldenstrom's Macroglobulinemia reacts to the COVID-19 vaccine.
There is considerable morbidity and mortality associated with cardiac surgery. Currently little effort is made to quantify how well the immune system of an individual can cope with inflammation or infection to which they are exposed during surgery. The investigators have previously demonstrated that having higher pre-operative antibody levels is associated with a lower risk of infection and a shorter stay in hospital after cardiac surgery. The investigators aim to study 150 patients undergoing aortic valve replacement and explore their dynamic immune responsiveness. The investigators will determine if this response is correlated with the post-operative outcome (development of post-operative infection or increased length of hospital stay). The investigators will compare this response with the previously measured static markers of immune competence and also with a novel device that may give a more rapid measure of dynamic immunity. The investigators will approach patients in the cardiac surgical pre-assessment clinic to see if they are willing to participate in the study. Immediately once under anaesthetic blood will be taken for testing and then again at the end of surgery, 24h after surgery, at discharge from hospital, and at follow-up clinic approximately 4 weeks later. There will be no additional needle insertions on top of those routinely performed. The investigators will collect data from the routine observations as far as 1 year after surgery. If the investigators can show an association between immune function and subsequent post-operative outcome it may be possible to determine ways to improve outcomes for patients undergoing heart surgery. This might include better information on risks and benefits of surgery, actively boosting immune function (vaccination, immune-nutrition), passively improving immunity (administering antibodies), or consider current alternatives to open heart surgery where the threat of infection or inflammation may be markedly reduced (eg trans-catheter aortic valve implantation)
