FAQ: Phase 3 GALAXI 2 & 3: Extraintestinal Manifestations In Moderate to Severe Crohn’s Disease

Thank you to Johnson & Johnson for the support on this FAQ Video Module.

This FAQ video features Janette Villalon, PA, who reviews the role of guselkumab in treating extraintestinal manifestations in patients with moderately to severely active Crohn’s disease. In this expert-led discussion, she summarizes findings from the GALAXI 2 and GALAXI 3 clinical trials presented at a 2026 medical congress, which used a treat-through study design intended to reflect real-world clinical practice. The focus of the analysis is on how patients with Crohn’s disease respond over time when treated with guselkumab compared to placebo.

The data presented focuses on key outcomes such as improvement and resolution of extraintestinal manifestations, including joint and skin symptoms, along with measures like steroid-free remission and the emergence of new symptoms over time. At baseline, a notable proportion of patients in both the guselkumab and placebo groups had extraintestinal involvement, most commonly arthralgia, with skin manifestations occurring less frequently.

This educational FAQ highlights how clinicians are evaluating guselkumab as part of a broader strategy for managing Crohn’s disease, with attention to both symptom control and durability of response over time. It provides practical insights for gastroenterology advanced practice providers and healthcare professionals as they balance effectiveness, long-term disease control, and comprehensive care of patients with inflammatory bowel disease in clinical practice.
