An IL-23 Blocker Healed Intestines and Eased Crohn's Symptoms in 38% of Patients

Researchers tested mirikizumab, an antibody that blocks a protein called IL-23, in people with moderate-to-severe Crohn's disease who hadn't responded well to other treatments. After one year, 38% of patients on mirikizumab showed healing in their intestines and symptom improvement, compared to 9% on placebo.

What the trial was testing

The VIVID-1 enrolled 1,158 patients with crohn's disease. The study was sponsored by Eli Lilly and Company and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.

What the results showed

38% of patients showed intestinal healing and symptom relief after one year of treatment.

Lancet (London, England) · 2024 · NCT03926130

These findings — that patients showed both intestinal healing and symptom improvement after one year — were published in the Lancet (London, England) and represent the headline result of the study.

Researchers tracked outcomes across 1,158 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with crohn's disease, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

Mirikizumab is FDA-approved for Crohn's disease as of 2024. This large study showed it can help patients who haven't responded to other biologics or standard treatments. Talk to your gastroenterologist about whether mirikizumab might be right for you, especially if you've tried other medications without success.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Intermittent Caloric Restriction in Patients With Mild to Moderate Crohn's Disease

Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal (GI) tract. CD is a common inflammatory bowel disease (IBD), frequent (150,000 patients in France and 1.5 million in Europe), disabling and incurable. The environmental factors, and in particular diet, play a major role in the pathogenesis of CD. The prevalence of CD is steadily increasing in highly industrialized countries, where the Western diet rich in saturated fats and refined sugars, is blamed for this to explain this true pandemic. On the other hand, enteral nutrition, exclusive or partial, is known to be effective in the initial treatment of CD, especially in pediatrics. There are a number of evidence in favor of a nutritional management nutritional management of caloric restriction during inflammatory diseases such as psoriasis and rheumatoid arthritis,whose physiopathology is similar to that of IBD. To date, and despite patient concern, there is no consensus nutritional in the management of CD to influence the natural course of the disease. The investigators have decided to initiate a clinical study to evaluate for the first time the efficacy, acceptability and safety of intermittent caloric restriction in patients with CD.
