What is the purpose of this trial?

This trial tests a new treatment called Afimkibart (also known as RO7790121) for people with Crohn's disease, which causes inflammation in the digestive tract. The study aims to determine the effectiveness and safety of Afimkibart for individuals with moderately to severely active Crohn's disease who haven't found success with other treatments. Participants will receive either Afimkibart or a placebo (a harmless, inactive substance) to compare results. Suitable candidates have Crohn's disease that hasn't responded well to other therapies and are experiencing significant symptoms. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop your current medications. However, it mentions that certain medicines are prohibited, including anti-TL1A therapy, so you may need to discuss your current medications with the trial team.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research shows that afimkibart (RO7790121) is being tested for safety in people with Crohn's disease. Earlier studies on afimkibart, which targets a protein linked to inflammation, found it to be generally well-tolerated. Some participants experienced mild side effects, such as headaches and injection site reactions. The current studies aim to gather more detailed safety information, but existing evidence suggests that afimkibart is safe enough for further testing in larger patient groups. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Crohn's disease?

Unlike the standard treatments for Crohn's Disease, which often include medications like corticosteroids, immunosuppressants, and TNF inhibitors, afimkibart offers a novel approach. Researchers are excited about afimkibart because it introduces a unique mechanism of action, potentially targeting pathways not addressed by current therapies. Additionally, it offers a new delivery method, combining intravenous (IV) and subcutaneous (SC) administration, which might enhance its effectiveness and patient convenience. This fresh approach could bring new hope to those who haven't responded well to existing treatments.

What evidence suggests that RO7790121 might be an effective treatment for Crohn's disease?

Research shows that afimkibart, a type of medication, may help treat moderate to severe Crohn's disease. Earlier studies found that afimkibart had a good balance of benefits and risks. Some patients noticed significant improvements in their symptoms. Specifically, about 48% of patients in one study reported positive effects during the initial treatment phase, and 59% experienced benefits during ongoing treatment. In this trial, participants will receive afimkibart in one of the experimental arms. These findings suggest that afimkibart could be a useful option for managing Crohn's disease symptoms. ^{1 2 3 4 6}
