Participate in Research

Research studies help find new methods for diagnosing, treating, managing, and preventing Crohn's disease and ulcerative colitis. Even the most promising scientific findings must first be proven to be safe and effective before they can be used in the management of inflammatory bowel disease (IBD).

If you are interested in learning more about participating in a research study or clinical trial, speak with your doctor.

For Researchers recruiting patients for study participation

  • Transcranial magnetic stimulation (TMS) is a safe, non-invasive, FDA approved technique that uses non-invasive magnetic fields to stimulate targeted brain cells. This has been found to help improve mental health conditions like anxiety & depression, and also reduce the use of psychotropic medications. The purpose of this study is to determine if patients with Crohn’s disease or ulcerative colitis who have anxiety, depression, or other symptoms respond to TMS treatment.

    Who can participate?
    Male and female Crohn’s disease and ulcerative colitis patients who have anxiety, depression, or abdominal pain, despite being on stable IBD medications.

    You must reside in or be able to commute to Calgary

  • The use of medical cannabis has received increasing attention for its potential role in inflammation and immune function for IBD. In this study, we explore patients' perceptions and experiences with cannabis to manage IBD symptoms and improve quality of life and disease outcomes. 

    This survey is open to all patients with IBD who live in Saskatchewan. We would like to hear from everyone with IBD regardless of their personal history with cannabis. Everyone is welcome – those who are currently using cannabis products to those who have never used it before.

    The research aims are to 1) develop a better understanding of cannabis use in IBD; 2) explore patient's experiences/beliefs on medical cannabis use for IBD, and to 3) improve outcomes for patients with IBD and ensure that medical cannabis is used safely and effectively. The survey will take 10-15 minutes to complete. 

    Who can participate?
    1) diagnosed with IBD; 
    2) 18 years of age and older; 
    3) residents of Saskatchewan.

  • The purpose of this study is to obtain an understanding of perceived health-related quality of life (HRQOL) and care experiences in older adults with IBD. The objectives are to: 1) assess perceived HRQOL and chronic illness care in older adults with IBD; and 2) explore the care experiences of older adults with IBD living in Canada. The older adult age group is the fastest growing group of individuals with IBD and obtaining perspectives about older adult’s goals of care and how the care received impacts their quality of life are important considerations for future health service delivery plans. There is not a lot of information on the perspectives from older adults with IBD and our research team wants to increase knowledge in this area. 

    This project is a 1 year study with 2 ways to participate (You can participate by selecting one or both options). 

    1. An anonymous online or paper survey – The survey will take you about 20-40 minutes to complete. 

    2. A confidential telephone or online interview - The research team is looking to conduct 30-60 minute interviews with older adult patients who have IBD. The interview questions will ask you about your IBD history and what it is like living with IBD as an older adult. 

    Who can participate? You can help us if you: 
    1. Have been diagnosed with Inflammatory Bowel Disease (IBD) (either Crohn’s Disease or Ulcerative Colitis). Diagnosis could have occurred at any age
    2. Are currently 60 years of age or older. 
    3. Are able to read and speak English fluently. 
    4. Live in Canada

  • This study is part of a global research effort to follow IBD patients at infusion centers around the world. We will measure the baseline prevalence of SARS-CoV-2, the virus that causes COVID-19, exposure by antibody testing (involves taking a blood sample) and follow with scheduled testing (blood sample at each of the visits) every 8 weeks over a 48-week period.

    Through analysis of clinical data and patients’ social behaviors(questionnaire), we will be able to identify social, treatment-related, and biological factors that determine whether patients acquire mild, asymptomatic, or severe disease. This study could lead to improvements in understanding the effects of medications and viral infections in IBD and help on future pandemic preparations and epidemiological studies.

    Who can participate? 
    1. Participants 18 years or older
    2. Been diagnosed by your physician with IBD (Crohn’s Disease, Ulcerative Colitis, IBD-U)
    3. Currently receiving treatment for IBD with Infliximab, other biologics or Vedolizumab
    4. May or may not been diagnosed with COVID-19.

  • Patients with ulcerative colitis (UC) may undergo colectomy due to a variety of reasons. Ileal-pouch anal anastomosis is often offered to these patients. Unfortunately the pouch commonly develops inflammation, known as pouchitis, which is the most common complication of this procedure and occurs in approximately 50% of patients, with the majority of these patients having multiple episodes.

    Enrolling now for Fecal Microbiota Transplant (FMT) for Patients with Active Pouchitis. The study focuses on use of fecal microbiota transplantation for treatment of pouchitis. The study objectives are to learn about a) if alteration of the microbiota in pouchitis helps improve disease symptoms; and b) understand the changes that occur in the gut bacteria during fecal transplantation. This is a randomized controlled trial of fecal microbiota transplantation versus placebo for treatment of pouchitis.

    Who can participate?
    1. Be 18 or over and be able to give informed consent.
    2. Have symptoms of active pouchitis.
    3. Have evidence of active pouchitis in screening pouchoscopy.

    Qualified Participants Receive:
    1. Study-related care from gastroenterologist including screening pouchoscopy and final pouchoscopy.
    2. Once weekly FMT enemas for at least 6 weeks.
    3. Compensation for parking.
