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 aim is to investigate if changes in sex hormones during the menstrual cycle affects cough sensitivity in females and males with mild allergic asthma. Female subjects will be grouped according to natural cycle, or taking oral contraceptives. Male subjects will act as the control group.
This is a 2-part, phase 3 clinical study evaluating the antiretroviral activity and safety/tolerability of islatravir (ISL), doravirine (DOR), and a fixed dose combination (FDC) of DOR/ISL (also known as MK-8591A) in heavily treatment-experienced (HTE) participants with human immunodeficiency virus type 1 (HIV-1) infection. It is hypothesized that the percentage of participants receiving DOR/ISL to achieve ≥0.5 log10 decrease in HIV-1 ribonucleic acid (RNA) from study baseline (Day 1) to Day 8 is superior to placebo, each given in combination with failing antiretroviral therapy (ART).
This is a pilot randomized, double-blind, active-controlled, 2-treatment, crossover study to evaluate the PK, user experience and abuse liability of manipulated ADAIR compared to a manipulated commercially-available d-amphetamine sulfate IR formulation administered intranasally in non-dependent recreational stimulant users. The study is comprised of 4 phases: Screening, Qualification, Treatment, and Follow-up/Early Termination.
This study will examine the feasibility and effect of a program that combines exercise and feedback from a wearable device on upper limb movement practice and function in individuals with stroke.
During exercise in conditions of low oxygen (termed hypoxia), such as mountaineering at high altitudes, the lung blood vessels constrict in an attempt to protect the body from the negative effects of hypoxia. It appears that this blood vessel constriction may limit the heart to pump blood during heavy exercise, leading to reductions in exercise performance. Inhaled nitric oxide is a drug that is known to relax the lung blood vessels. Inhaled nitric oxide has been used to relax lung blood vessels and improve exercise capacity in patients with chronic disease. It is unknown if similar improvements would be observed during exercise in healthy individuals when exposed to low levels of oxygen. The goal of this study is to determine if inhaled nitric oxide can relax the lung blood vessels and improve the heart's pumping ability during exercise in low oxygen conditions. Further, the investigators will determine if these improvements in lung blood vessel and heart function increase exercise performance. Participants will complete 6 sessions over a three week period where they will perform exercise challenges while breathing low levels of oxygen with and without inhaled nitric oxide. The low oxygen conditions will be comparable to being at an altitude of 14,000-17,000 feet. 17,000 feet would be equivalent to standing on the summit of King Peak in the Yukon (the 4th tallest mountain in Canada).
This is a Phase 1, first-in-human, open-label, multicenter study of CC-97540, CD19-targeted NEX-T chimeric antigen receptor (CAR) T cells, in subjects with relapsed or refractory B-cell non-Hodgkin lymphoma. The study will consist of 2 parts: dose-escalation (Part A) and dose-expansion (Part B). The dose-escalation part (Part A) of the study is to evaluate the safety and tolerability of increasing dose levels of CC-97540 to establish a recommended Phase 2 dose (RP2D); and the dose-expansion part (Part B) of the study is to further evaluate the safety, pharmacokinetics/pharmacodynamics, and efficacy of CC-97540 at the RP2D.
Posttraumatic stress disorder (PTSD) is a common and disabling condition associated with intimate relationship problems and mental health problems in partners of those with PTSD. Recognizing the need to improve access to evidence-based interventions for those with PTSD and their families, our team has developed an Internet-delivered, self-help intervention to improve PTSD, enhance relationships, and improve partners' mental health: Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction). Couple HOPES presents text and video-based content across seven self-help intervention modules, with modest support from paraprofessional coaches. Although the Couple HOPES platform has been developed, it remains uncertain whether Couple HOPES is feasible, usable, and efficacious in reducing PTSD and enhancing intimate relationship functioning. The proposed project aims to refine and finalize Couple HOPES with couples that include a veteran, service member or first responder with significant PTSD symptoms. This project includes initial testing of the intervention's preliminary efficacy, safety, and feasibility in a series of 10 couples (Phase 1), then in an uncontrolled trial of 20 couples (Phase 2), and then a randomized clinical trial comparing its efficacy to a delayed intervention control condition in 70 couples. Potential benefits of this study include couples learning new skills to reduce PTSD symptoms and enhance relationship functioning, although this is not guaranteed. Risks include participants finding the assessments distressing, or possible worsening of PTSD symptoms or relationship functioning. These risks will be mitigated by continuous monitoring of PTSD symptoms, relationship functioning, and adverse events, and intervention by study staff.
Depression and anxiety are common and prevalent conditions that are frequently under treated. In an attempt to increase timely and accessible psychological treatment, Internet-delivered Cognitive Behaviour Therapy (ICBT) has emerged. ICBT involves delivering therapeutic content to manage depression and or anxiety via structured online lessons. This is often combined with brief therapist guidance, for example once per week for 8 weeks via secure messaging or phone calls. Although outcomes of ICBT are very impressive, there is room for improvement in terms of completion rates and outcomes. Feedback from patients suggest that some patients would prefer longer term support or follow-up care. In this two-factorial randomized controlled trial, the investigators aim to contribute to the literature by examining whether the efficacy of ICBT is improved by offering an extended period of support to clients (from 8 weeks to 12 weeks) and being offered a booster session at 16 weeks after treatment enrollment (yes vs no). Follow-up assessments will be conducted at 8, 16 and 26 weeks after treatment enrollment. Primary outcomes are reduced anxiety and depression. Secondary outcomes include reduced panic, social anxiety, trauma, quality of life, disability, work productivity, and healthcare use.
Hip fracture is a major health problem facing older adults. Hip fractures result in higher mortality, morbidity, and costs than all other osteoporotic fractures combined. When returning home following hip fracture surgery, patients are at high risk of adverse outcomes (e.g., secondary fractures, institutionalisation, and death). Objectives: This study aims to finalize and pilot test a new program of care including a user-friendly toolkit containing a home-based physiotherapy exercise and pain management program to help community-dwelling older adults recover after hip fractures. Methods: This study will be two stages: First, finalizing the program. The investigators have created a self-explanatory toolkit that includes an illustrated exercise program based on a critical analysis of previous programs for hip fracture patients. The investigators will organize focus groups and conduct semi-structured interviews with patients, caregivers, policymakers, and healthcare providers to review the program and provide feedback. Second, conducting a feasibility study. The investigators will pilot the program in a randomized trial with community-dwelling hip fracture patients and compare the intervention with conventional care. Expected Outcomes: While the number of hip fracture survivors is increasing, they are becoming frailer, and their functional recovery has not improved, making this study timely and relevant. With the current focus on helping older adults "age in place," the proposed project addresses a vital health system challenge: helping older hip fracture patients access proper rehabilitation, so they can stay independent in their homes.
When a person living with dementia moves into a long term care facility, their family members remain involved in their care. They learn new roles and make significant and often stressful adjustments. These caregivers are an at-risk group, and evidence suggests that their mental health may actually worsen after the person they are caring for moves into long term care. The research team previously created a free, web-based, interactive, intervention called My Tools 4 Care-In Care (MT4C-In Care) and tested it with 37 caregivers in Alberta. Caregivers found the toolkit to be easy to use, feasible, acceptable, and satisfactory, and reported increased hope and decreased loss and grief, after using it. Additionally, they reported that the toolkit helped them through the transitions they experience when their family member lives in long term care. In this next study we want to see if MT4C-In Care can improve the quality of life, hope, social support, self-efficacy, and decrease the loss, grief and loneliness of family caregivers. During phase 1 the existing MT4C-In Care toolkit was reviewed with input from family caregivers of persons living with dementia in long term care through focus group interviews. The toolkit is now being revised and will be tested, during phase 2, with 280 caregivers of persons living with dementia in long term care across 4 provinces in Canada (Alberta, Ontario, Saskatchewan, and Manitoba). These caregivers will be randomly assigned into an intervention (caregivers with access to MT4C-In Care) and a control group (no access to MT4C-In Care).
