What the SEAVUE Trial Found — Ustekinumab vs. Adalimumab for Crohn's Disease

Researchers compared two biologic drugs, ustekinumab and adalimumab, in people with moderate to severe Crohn's disease who hadn't taken biologics before. After one year, both drugs worked about equally well at controlling symptoms.

What the trial was testing

The SEAVUE enrolled 386 patients with crohn's disease. The study was sponsored by Janssen Scientific Affairs, LLC 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

Around 65% of patients on ustekinumab and 61% on adalimumab were in remission after one year.

Lancet (London, England) · 2022 · NCT03464136

These findings — that both drugs brought about two-thirds of patients into remission with no clear winner — were published in the Lancet (London, England) and represent the headline result of the study.

Researchers tracked outcomes across 386 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

Both ustekinumab and adalimumab are FDA-approved for Crohn's disease. This trial showed they work about equally well for people starting their first biologic. Talk with your gastroenterologist about which option might fit your treatment plan and insurance coverage.

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.
