What is this Study About?

The IMAGINE Network is currently recruiting healthy individuals along with persons with inMammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Our goal is to recruit 8,000 subjects and will study how three important variables (genes, diet and mental health) impact the gut microbiome and, in turn, how together they impact the disease course.

Who can Participate?

Adults or children with IBD or IBS, or healthy subjects

This study has been approved by the Hamilton Integrated Research Ethics Board (REB #3000).

What is this Study About?

PALI-2108 is a new oral medication designed to treat ulcerative colitis (UC) by targeting the intestines. It works as a phosphodiesterase-4 (PDE4) inhibitor prodrug, meaning it becomes active only after being processed by bacteria in the colon. This targeted approach reduces the risk of side effects that can occur with other medications that affect the entire body.

Recent studies have shown that patients with active UC, especially those with moderate to severe symptoms, have higher levels of PDE4 and related biomarkers. These biomarkers are linked to the severity of their disease, suggesting that inhibiting PDE4 could help manage UC effectively.

The goal of this Phase 1 study is to evaluate the safety, tolerability, and how the body processes (pharmacokinetics) and responds to (pharmacodynamics) PALI-2108 in healthy volunteers. Although there are already PDE4 inhibitors on the market, PALI-2108 is a completely new compound that has not been tested in humans before.

Who can Participate?

You are invited to take part in this research study if:

• You are aged at least 18 years but not older than 70 years
• Your body mass index (BMI) is within 18.5 kg/m2 to 35.0 kg/m2, inclusively
• You have received a diagnosis of moderate to severe UC, established at least 6 months prior to screening
• You are located in Montreal, QC or are willing to commute to our location

Your Role in this Study

The study will involve two parts: first, participants will receive single doses of the drug, and then, in the second part, they will take it twice a day for seven days.

The twice-daily dosing schedule is designed to maximize drug exposure in the colon. The investigators will also investigate how food affects the drug's absorption.

Additionally, a small group of stable UC patients will be included in the study. These patients will also take PALI-2108 for seven days, allowing us to compare the safety and drug processing between healthy individuals and those with UC. The investigators will monitor important health markers and conduct tests on colon tissue to see how well the drug works and if it causes any changes in the tissue.

Including UC patients early in this research is important for understanding how the drug performs in real-world conditions. This data will help refine our approach to identify which patients might benefit most from PALI-2108 in future studies.

Overall, this study aims to gather crucial information about PALI-2108's safety and effectiveness, paving the way for new treatment options for patients with ulcerative colitis.

What is this Study About?

The aim of this initiative is to gather culturally relevant information on the care and management of inflammatory bowel disease (IBD). This information will be used to guide the development of educational materials presented in Arabic, Farsi, Filipino/Tagalog, Hindi, Mandarin, Punjabi, and Spanish. These materials will be made widely available to Canadians with the hope of making IBD resources more accessible.

Who can Participate?

You are invited to take part in this research study if:

• You have inflammatory bowel disease (IBD), Crohn’s Disease (CD), or Ulcerative Colitis (UC)
• You are not optimally fluent in English
• You are a speaker of one of the following languages: Arabic, Farsi, Filipino/Tagalog, Hindi, Mandarin, Punjabi, and/or Spanish
• You immigrated to Canada from another country (you are a new Canadian)

Your Role in this Study

Individuals who are living with IBD, were born outside of Canada, and are primarily fluent in Arabic, Farsi, Filipino/Tagalog, Hindi, Mandarin, Punjabi, and/or Spanish will be invited to participate in a 2.5 hour-long virtual focus group with 4-5 other individuals and 1 facilitator. During the focus group, participants will be asked to speak about their experiences around being diagnosed with IBD, making decisions around medications for their IBD, and about their diet and mental health as it relates to IBD. Conversations during the focus group will be audio recorded so they may later be used to develop educational materials in each language. No personally identifying information will be collected. Participants may refuse to answer any questions and if need be, withdraw from the group at any time. A token of appreciation will be provided to those who decide to participate in this educational initiative.

What is this Study About?

There are multiple treatments in Crohn's disease (CD). Most of the studies approving these drugs include a placebo arm with very few studies to date (SEQUENCE, SEAVUE, VIVID-1) including direct comparisons between drugs. One of the key research questions set out by the UK James Lind Alliance research priority setting partnership scheme is "what is the best treatment or sequence of treatments in Inflammatory Bowel Disease?"

To answer the question of which is the best treatment and which is the best sequence of treatment we have undertaken a network meta-analyses. The evidence (both the direct comparisons, real world data sets and the network-meta-analyses) show that most drugs are very similar in efficacy and it is still hard to decide which is the best treatment in CD. To best answer this question we feel that a multi-arm, multi-intervention strategy (MAMS) trial is needed to compare all present treatments in CD.

Moreover, small cohort studies are suggesting that combination of advanced therapies may be very effective. We plan a multi-arm multi-intervention trial to investigate and compare the efficacy of single and combination advanced therapies in CD.

Who can Participate?

• Adults (over 18 years of age) who have IBD
• Medical professionals
• Nursing professionals
• Pharmacists
• Healthcare service managers and commissioners

Your Role in this Study

We need your help to design this study. Everyones opinion and experiences will be helpful in helping the research team to design this clinical trial. We want to hear from all kinds of people with experiences of CD - including people living with the condition or caring for people who have it.

We are now investigating the opinions, perceptions and expectations of the appropriate population(s), intervention(s) and comparator(s) which should be included in a platform MAMS trial for assessing safety, efficacy and cost effectiveness of advanced therapies in CD. We  want your opinion if and when should combination advanced therapies be used in a research study in CD. The steering committee of this study have undertaken an initial discussion on the trial design for this study.

This study has been approved by the University of Nottingham's Research Ethics Board (REB #FMHS 54-1224).

What is this Study About?

Tulisokibart is an anti-TL1A monoclonal antibody. TL1A is shown to be upregulated in mucosa (colon) and serum (blood) of patients with IBD. Through this process, it has the potential to improve inflammatory and fibrotic diseases related to the immune system.

Who can Participate?

• Individuals 18-75 years of age (inclusive)
• Diagnosed with Crohn’s Disease or Ulcerative Colitis
• Located in Toronto, ON or is willing to commute to our location for treatment

Your Role in this Study

A phase 2 study was completed with Tulisokibart in patients with moderate to severe Crohn’s Disease and Ulcerative Colitis. Majority of the patients included in this study have failed infliximab (Remicade, Humira, etc) and/or vedolizumab (Entyvio). The phase 2 results were positive and demonstrated that patients treated with Tulisokibart were more likely to achieve clinical remission (0-2 more bowel movements than normal and no rectal bleeding), endoscopic improvement (no inflammation or mild inflammation), and clinical response (30% reduction in stool frequency and rectal bleeding) after 12 weeks of treatment compared to patients on placebo. As a result of these positive results, Health Canada, FDA, and EMA approved this phase 3 study.

This Phase 3 Study is placebo controlled with 25% chance of entering the placebo treatment group. However, if at the end of the first 12 weeks you are not responding to the medication (symptoms and inflammation in your colon does not improve), participants will be able to transition to a new group and receive Tulisokibart (no chance of placebo).
