What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying Crohn's disease, a condition that causes inflammation in the digestive tract, leading to symptoms like abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition. The trial will evaluate a treatment called risankizumab, which is administered as a solution for injection using a pre-filled syringe. Risankizumab is being compared to a placebo to determine its effectiveness and safety for individuals with moderately to severely active Crohn's disease.

The purpose of the study is to assess how well risankizumab works and how safe it is for patients. Participants in the study will receive either risankizumab or a placebo through subcutaneous injections, which means the medication is injected under the skin. The study will monitor participants over a period of time to see if there is an improvement in their symptoms and overall health. The trial aims to find out if risankizumab can help achieve clinical remission, which means a significant reduction in disease activity, and if it can lead to an endoscopic response, indicating healing of the intestinal lining.

Throughout the study, participants will be closely observed to ensure their safety and to gather information on how the treatment affects their condition. The trial will also look at secondary outcomes, such as changes in fatigue levels and other symptoms related to Crohn's disease. The findings from this study could provide valuable insights into the potential benefits of risankizumab for people living with Crohn's disease.

The research process

The trial runs in 6 steps – from screening to follow-up. Each step says what happens and what the team monitors.

Step 1
Initial visit
Upon joining the study, you will attend an initial visit. During this visit, your eligibility for the trial will be confirmed based on specific criteria, such as age, diagnosis of Crohn's disease, and previous treatment history.
You will undergo a series of assessments, including a review of your medical history and a physical examination. This is to ensure that you meet all the necessary requirements to participate in the trial.
Step 2
Baseline assessments
Baseline assessments will be conducted to evaluate the current state of your Crohn's disease. This includes measuring your Crohn's Disease Activity Index (CDAI) and performing an endoscopy to assess mucosal inflammation.
These assessments help establish a starting point for your condition, which will be used to measure the effectiveness of the treatment.
Step 3
Treatment administration
You will be randomly assigned to receive either the study medication, risankizumab, or a placebo. The medication is administered as a subcutaneous injection, which means it is injected under the skin.
The treatment will be given according to a specific schedule over a period of 12 weeks. The exact dosage and frequency will be explained to you by the study team.
Step 4
Regular follow-up visits
Throughout the 12-week treatment period, you will have regular follow-up visits. These visits are important for monitoring your health and the effects of the treatment.
During these visits, you will undergo various assessments, including physical examinations, blood tests, and questionnaires about your symptoms and overall well-being.
Step 5
End of treatment assessments
At the end of the 12-week treatment period, you will have a final set of assessments. These will include another measurement of your CDAI and an endoscopy to evaluate any changes in mucosal inflammation.
The results of these assessments will help determine the effectiveness of the treatment in managing your Crohn's disease.
Step 6
Post-trial follow-up
After completing the treatment phase, you may be asked to participate in follow-up visits. These visits are designed to monitor your long-term health and any lasting effects of the treatment.
The study team will provide you with detailed information about the schedule and nature of these follow-up visits.

Investigated drugs

Risankizumab is a medication used in this clinical trial to help people with Crohn's Disease, which is a condition that causes inflammation in the digestive tract. This medication is given as an injection under the skin. It works by targeting a specific part of the immune system that is involved in causing inflammation. By doing this, Risankizumab aims to reduce the symptoms of Crohn's Disease, such as abdominal pain and diarrhea, and help patients feel better. The trial is designed to see how effective and safe Risankizumab is for people with moderate to severe Crohn's Disease.

Risankizumab

What is already known about the treatment

Risankizumab – Risankizumab is administered as a subcutaneous injection, meaning it is given under the skin. It is currently being studied in clinical trials for its effectiveness and safety in treating Crohn's disease, a condition that causes inflammation of the digestive tract. The medication works by targeting a specific protein in the body called interleukin-23 (IL-23), which plays a role in inflammation. By blocking IL-23, risankizumab helps reduce inflammation and alleviate symptoms of Crohn's disease. It is classified as a monoclonal antibody, a type of drug designed to target specific molecules in the body.

Investigated diseases

Crohn's disease – Crohn's disease is a chronic inflammatory condition of the gastrointestinal tract, primarily affecting the small intestine and colon. It is characterized by periods of active disease, known as flares, and periods of remission. During flares, individuals may experience symptoms such as abdominal pain, diarrhea, fatigue, and weight loss. The inflammation can lead to complications like strictures, fistulas, and abscesses. The disease can affect any part of the gastrointestinal tract from the mouth to the anus, and the inflammation can penetrate through the entire thickness of the bowel wall. The exact cause of Crohn's disease is unknown, but it is believed to involve a combination of genetic, environmental, and immune system factors.
