Study of AZD7798 compared to placebo in patients with moderate to severe Crohn’s disease

2 1

What is this study about?

This study focuses on people with moderate to severe Crohn’s Disease, a condition that causes inflammation in the digestive system. The study will test a new medication called AZD7798, which is given as an injection under the skin. Some participants will receive the actual medication, while others will receive a placebo.

The purpose of this study is to determine how effective and safe AZD7798 is in treating Crohn’s Disease. The medication will be provided as a freeze-dried powder that is mixed into a solution before injection. The study will look at how well the treatment works in reducing disease symptoms and improving the condition of the intestines.

During the study, participants will receive subcutaneous (under the skin) injections of either AZD7798 or placebo for up to 48 weeks. The study will monitor various aspects of the disease, including symptoms such as abdominal pain and stool frequency, as well as examining the healing of the intestinal lining. Blood samples will be taken to measure the amount of medication in the body and to check for the development of antibodies against the study drug.

1 Initial assessment

Your eligibility for the study will be evaluated based on your Crohn’s disease diagnosis and current condition.

A video recording of your intestines (ileocolonoscopy) will be performed to assess inflammation levels.

Your disease activity will be measured using a special score called CDAI (Crohn’s Disease Activity Index).

2 Treatment assignment

You will be randomly assigned to receive either AZD7798 or a placebo (inactive substance).

Neither you nor your doctor will know which treatment you are receiving during the study.

3 Treatment administration

You will receive injections under the skin (subcutaneous) of either AZD7798 or placebo.

The medication comes in the form of a solution prepared from a freeze-dried powder.

4 Monitoring and evaluation

Your disease activity will be regularly monitored using the CDAI score.

The effectiveness of the treatment will be measured by checking if your CDAI score becomes less than 150 (indicating remission).

Additional evaluations will include checking your stool frequency and abdominal pain levels.

Another video recording of your intestines will be performed to measure changes in inflammation.

5 Study duration

The study is scheduled to run from June 2024 to May 2027.

Blood samples will be taken to measure the amount of medication in your body and check for antibodies against the study drug.

Trial locations

Investigated Drugs:

AZD7798 is an investigational medication being studied for treating moderate to severe Crohn’s Disease. This medication is being tested to see if it can help patients achieve remission of their Crohn’s Disease symptoms. It is being compared to a placebo to determine its effectiveness and safety in controlling inflammation and reducing disease activity in patients with Crohn’s Disease.

Crohn’s Disease – A chronic inflammatory bowel disease that can affect any part of the digestive tract, from the mouth to the anus. The condition typically causes inflammation of the deep layers of the digestive tract, leading to abdominal pain, severe diarrhea, fatigue, and weight loss. The disease often develops gradually, with symptoms worsening over time, and can affect different parts of the digestive tract in different people. The inflammation can spread deep into the layers of affected bowel tissue, and healthy parts of the digestive tract can be interspersed between inflamed areas. Crohn’s Disease is characterized by periods of active symptoms alternating with periods of remission.
