Background:
Real-world effectiveness and safety of upadacitinib in patients with Crohn's disease (CD) remain unclear.
Aims:
This study aimed to evaluate the effectiveness and safety of upadacitinib in a real-world cohort.
Methods:
From September 2022 to June 2024, all consecutive patients with refractory luminal CD treated with once daily upadacitinib 45 mg in 29 French GETAID centres were retrospectively included. The primary outcome was steroid-free clinical remission (SFCR) at week 12, defined as a Harvey-Bradshaw Index (HBI) of < 4. Clinical response (decrease of ≥ 3 points in HBI and/or HBI < 4), clinical remission, biomarker remission, endoscopic and/or radiologic response and safety were also assessed.
Results:
Among the 223 patients included, all were previously exposed to at least one biologic (median 4, IQR [3, 4]) and 119 (53.8%) had prior intestinal resection. At week 12, SFCR was achieved in 107/197 (54%), clinical response in 129/197 (65%) and clinical remission in 111/197 (56%). A total of, 90 out of 173 (52%) achieved biomarker remission. Endoscopic and/or radiologic response was observed in 18/38 (47%) patients. Clinical response of extraintestinal manifestations was observed in 37/47 (79%) patients and clinical remission in 29/47 (62%). A total of, 65 adverse events (AEs) occurred in 58 patients (26%), including 17 serious AEs, 16 disease exacerbation and one case of colonic EBV-associated lymphoproliferative disorder. Acne was reported in 24/223 (11%) patients.
Conclusion:
In this real-world cohort of highly refractory CD patients, upadacitinib induction resulted in a clinical response in about two-thirds of patients and in SFCR in half of the patients, with an acceptable safety profile.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
