Vedolizumab, Adalimumab, and Methotrexate Combination Therapy in Crohn's Disease (EXPLORER)

Clin Gastroenterol Hepatol 2024;22:1487–96 doi: 10.1016/j.cgh.2023.09.010

This Phase 4, prospective, open-label study provides additional support for the utility of vedolizumab, adalimumab, and methotrexate combination therapy in biologic-naïve patients with newly diagnosed, moderate to high-risk Crohn's disease. Investigators examined the efficacy of this triple therapy for achieving endoscopic and clinical remission at Week 26.

More RA patients on upadacitinib versus adalimumab achieved clinical remission, LDA, and DAS28 (CRP) <2.6. Radiographic progression was less with continuous upadacitinib versus continuous adalimumab. Upadacitinib showed similar safety to adalimumab, with higher incidences of HZ, lymphopenia, CPK elevation, hepatic disorder and nonmelanoma skin cancer.
