ClinConnect Summary

This clinical trial is studying a new treatment called RO7790121 for people with moderately to severely active Crohn's disease, a condition that causes inflammation in the digestive tract. The trial aims to understand how effective and safe this treatment is. It is currently recruiting participants aged 18 years and older who have been diagnosed with Crohn's disease and have not responded well to other treatments. To join the study, individuals must weigh at least 40 kilograms and meet specific health criteria.

Participants in this trial can expect to receive either the active treatment or a placebo (a substance with no active effect) during the study. The trial is double-blind, meaning neither the participants nor the researchers will know who is receiving the active treatment, which helps ensure the results are unbiased. It's important to note that certain health conditions, like other types of inflammatory bowel diseases or specific infections, may prevent someone from participating. This study provides a chance to contribute to research that could improve treatment options for Crohn's disease.
