Why This Matters

Long-term Phase 3 extension data suggest guselkumab (Tremfya) may provide sustained clinical and endoscopic remission for some adults with moderate-to-severe Crohn's disease, which could expand treatment options for patients who have not responded to other therapies.

Who Should Pay Attention

Adults with Crohn's disease, patients considering or currently on biologic therapy, gastroenterologists, and researchers following IL-23 inhibitors and long-term Crohn's outcomes.

What To Know

The report highlights high clinical remission rates at three years in patients remaining on study treatment, plus meaningful endoscopic remission percentages and high corticosteroid-free remission. Safety through Week 144 was reported as consistent with prior experience.

The findings are presented as long-term extension data from Phase 3 programs (GALAXI 2 and 3) and were presented at the ACG 2026 meeting, per the article.

Before making treatment decisions, patients should discuss with their gastroenterologist whether these trial populations and dosing schedules match their situation, and should review full study results (peer-reviewed publication or conference poster/abstract) for detailed methods, intent-to-treat analyses, and safety event rates.
